Quick Summary: Most foster carers looking after a child placed with them through a local authority cannot claim Child Benefit for that child, because the council is already paying toward the child’s accommodation and maintenance through the fostering allowance — and Child Benefit cannot be claimed where the local council is funding the child’s upkeep. However, important exceptions exist: connected persons and kinship carers with informal arrangements, carers whose council is not contributing to the child’s maintenance, and people in the process of adopting a child can all potentially claim. Foster carers are separately treated as self-employed for tax purposes and benefit from Qualifying Care Relief, which makes most fostering income tax-free. This guide explains every angle of how Child Benefit and fostering interact in 2026.

The Core Rule: Why Most Foster Carers Cannot Claim

The starting point for understanding Child Benefit and fostering is a single, clear rule from HMRC: you cannot claim Child Benefit for foster children in the standard local authority fostering arrangement, because the fostering allowance you receive already supports their needs.

This is confirmed directly by Kent Fostering’s guidance, echoing HMRC’s own position: you cannot claim child benefit for foster children, but if caring for disabled foster children you can apply for additional support separately (covered in section 14). The reasoning is straightforward and consistent with how Child Benefit operates throughout the system: it exists to help meet the cost of raising a child, and where another funding source — in this case, the local authority’s fostering allowance — is already meeting those costs, Child Benefit is not additionally payable.

This is not a punitive rule or a gap in the system. It reflects the basic design principle of Child Benefit: it is paid to the person who is financially responsible for a child’s upkeep, and in standard local authority fostering, that financial responsibility sits with the council, which is why the fostering allowance exists in the first place.

The Policy Logic Behind the Exclusion

It is worth understanding why this rule exists, rather than simply accepting it as an arbitrary administrative restriction, because the underlying logic helps explain many of the exceptions and edge cases covered later in this guide. Child Benefit was designed as a universal contribution toward the cost of raising a child, paid to the person bearing that cost. The fostering allowance system was separately designed, decades after Child Benefit’s introduction, specifically to ensure that local authorities meet the full cost of a looked-after child’s upkeep when that child is placed with a foster carer, recognising that fostering is fundamentally different from ordinary parenting: the local authority retains overarching responsibility for the child’s welfare, makes key decisions about the child’s care in partnership with (and sometimes independently of) the foster carer, and is legally obligated to ensure the child’s needs are met regardless of the carer’s personal financial circumstances.

Given this framework, paying Child Benefit on top of a local authority fostering allowance would mean the same underlying cost — supporting the child’s upkeep — was being met twice from public funds, once through the council’s children’s services budget and once through HMRC’s Child Benefit system. The exclusion exists to prevent this duplication, not to penalise foster carers, who in any case typically receive total fostering income (allowance plus professional fee) considerably higher than the value of Child Benefit alone, as illustrated in the payment level figures discussed later in this guide.

A Common Misconception Worth Addressing Directly

Some prospective and new foster carers approach fostering assuming that Child Benefit will be one of several income streams available to them, only to discover during the approval process that this is not the case. This is worth flagging clearly and early: the financial planning for any new foster carer should be based on the fostering allowance and professional fee structure offered by their specific local authority or agency, not on an assumption that Child Benefit will be separately available on top. Most fostering services explain this clearly during the assessment and approval process, but it remains one of the more frequently misunderstood aspects of the financial side of fostering, particularly among first-time carers who may be more familiar with Child Benefit from their own experience as parents than with the separate fostering payment system.

The Exact Legal Test HMRC Applies

HMRC’s own published guidance on Child Benefit eligibility sets out the precise test in plain terms: you’ll get Child Benefit if you foster a child, as long as the local council is not paying anything towards their accommodation or maintenance. This is the determinative question in every case — not whether you are formally a “foster carer,” but whether the council is contributing financially to the child’s upkeep.

Breaking Down the Test

The test is about the source and structure of funding, not the label attached to the arrangement. This is why “foster carer,” “kinship carer,” and “connected person” can all sit on different sides of the Child Benefit eligibility line depending on whether council money is funding the placement.

A Note on How This Differs From Most Other Child Benefit Eligibility Rules

It is worth pausing on how unusual this particular rule is within the broader Child Benefit framework. Most Child Benefit eligibility questions, as covered in our comprehensive guide to Child Benefit eligibility rules, turn on relatively fixed and knowable facts about the claimant — their immigration status, their residency, their relationship to the child, the child’s age and education status. The fostering exclusion is different in character: it turns on an external, administrative fact about a third party’s (the local authority’s) funding decisions, which can change over time even where the underlying caring relationship between the adult and the child remains completely stable and unchanged. This is precisely why the transitions described throughout this guide — from informal to formal kinship care, from fostering into special guardianship, from placement into finalised adoption — each carry their own distinct Child Benefit implications, even though from the child’s perspective, very little may have changed about their day-to-day life and care.

When Foster Carers CAN Claim Child Benefit

Despite the general rule, there are several genuine scenarios where someone caring for a child outside their own birth family can claim Child Benefit. These exceptions matter significantly to thousands of carers across the UK who fall outside the standard local authority fostering model.

Summary Table

Connected Persons and Kinship Foster Carers

“Connected persons” is the formal term used within the care system for relatives or family friends who become a child’s foster carer — as distinct from a carer with no prior connection to the child. Connected person foster carers (a relative, friend, or other person connected with a child) typically receive the age-related maintenance element of fostering payments, and may receive less than mainstream foster carers unless they undertake the standard fostering training required to access full reward and maintenance payments.

The Child Benefit Position for Connected Persons

Where a connected person becomes a formally approved foster carer through the local authority’s fostering panel process, and the council is paying a fostering allowance (even if at the reduced “connected persons” rate rather than the full mainstream rate), the same core rule applies: Child Benefit cannot be claimed, because the council is contributing to the child’s maintenance.

This catches some grandparents and other family members by surprise. A grandmother who steps in informally to care for her grandchild, expecting to claim Child Benefit as she would for any child she is responsible for, may find that once the arrangement becomes a formal connected persons foster placement — with the council paying an allowance — her Child Benefit eligibility ends, because the funding source has changed even though her day-to-day relationship with the child has not.

Why This Distinction Matters in Practice

The transition from an informal family arrangement to a formal connected persons fostering arrangement often happens specifically because the local authority becomes involved — for example, following a child protection concern, a parent’s illness, or a court process. Families in this situation should understand that formalising the arrangement through the council, while often providing valuable financial support, training, and professional backup, also changes the Child Benefit position. This is an important practical trade-off to discuss with your social worker when considering whether to move from an informal to a formal fostering arrangement.

The Approval Process and Its Financial Implications

Becoming an approved connected persons foster carer typically involves an assessment process broadly similar to that for any other prospective foster carer, including background checks, home visits, and an assessment of the carer’s ability to meet the child’s needs, though local authorities often run an expedited or temporary approval process for connected persons given the urgency that frequently surrounds these placements (a child needing immediate alternative care due to a crisis). During this approval period, financial arrangements can sometimes be provisional or different from the eventual ongoing rate, and carers should ask their social worker directly and in writing what the Child Benefit position will be once approval is confirmed, rather than assuming either outcome.

Many local authorities and family support organisations now provide written guidance specifically addressing this transition, given how often it causes confusion and occasionally results in carers continuing to claim Child Benefit after their circumstances changed without realising the financial landscape had shifted alongside the change in legal/administrative status. Asking the question explicitly and getting a clear written answer from your fostering team — ideally cross-referenced with a call to the Child Benefit Office itself — is the most reliable way to avoid an inadvertent overpayment situation arising later.

Special Guardianship Orders and Child Arrangements Orders

Special Guardianship Orders (SGOs) and Child Arrangements Orders represent a different legal category from fostering, and they have a correspondingly different relationship with Child Benefit.

Special Guardianship

A Special Guardianship Order gives the special guardian parental responsibility for the child, generally on a more permanent basis than a standard fostering arrangement, while preserving the birth parents’ legal status in a limited way. Special guardians often receive a Special Guardianship Support payment from the local authority — but this is typically structured differently from an ongoing fostering allowance, and depending on the specific arrangements made by the local authority (which can vary), it may not constitute the same kind of “accommodation or maintenance” payment that blocks Child Benefit eligibility.

In many cases, special guardians are eligible for Child Benefit, because once the order is made, the child is generally regarded as living with the special guardian under their own responsibility, rather than being in local authority care with a parallel fostering allowance in place. However, the specific terms of any financial support package agreed with the local authority at the time the SGO was made should be checked, since arrangements vary between councils and individual cases. If in doubt, contact the Child Benefit Office directly to clarify your specific position before assuming either way.

Child Arrangements Orders

A Child Arrangements Order (which replaced the old Residence Order) similarly establishes who a child lives with as a matter of family law, separate from the care system. A person named in a Child Arrangements Order as the person the child lives with is generally in the same position as any other person responsible for a child — they can claim Child Benefit in the standard way, provided the council is not separately funding the child’s maintenance through an ongoing fostering arrangement running in parallel.

Informal Arrangements: Looking After a Friend or Relative’s Child

HMRC’s guidance specifically addresses informal kinship arrangements that fall outside the formal care system entirely: you may be able to get Child Benefit if you’ve got an informal arrangement to look after a friend or relative’s child. You might not qualify if your local council is paying toward the child’s accommodation or maintenance — contact the Child Benefit Office to find out.

What “Informal” Means Here

This covers situations such as:

• A grandparent looking after a grandchild while a parent deals with a personal crisis, with no social services involvement
• An aunt or uncle caring for a niece or nephew by family agreement, without a court order or council funding
• A family friend stepping in to care for a child with the birth parents’ agreement, again without formal council involvement

In all of these cases, provided no local authority money is flowing to support the child’s accommodation or maintenance, Child Benefit can generally be claimed by the person who has taken on day-to-day responsibility for the child — using the standard “responsibility for a child” test that applies to any non-parent carer, as covered in our broader guide to Child Benefit eligibility rules.

Checking Your Specific Position

Because informal arrangements can sometimes have partial council involvement — for example, a small one-off payment, or a referral that has not yet become a formal fostering placement — it is worth contacting the Child Benefit Office directly (0300 200 3100) to clarify your specific position before assuming you are entitled to claim, particularly if there is any council involvement at all in your arrangement, however limited.

Adoption: Claiming Before the Process Is Complete

One of the most valuable and least well-known rules in this entire area: you can claim Child Benefit as soon as any child you’re adopting comes to live with you — you do not have to wait until the adoption process is complete.

This means that during the period a child is placed with prospective adopters, before the adoption order is finalised by the court, the prospective adopters can claim Child Benefit for that child, provided the standard residency and other eligibility rules are met. You might be able to get Child Benefit for a period before the adoption itself — contact the Child Benefit Office to find out the specifics of your situation, since the exact timing rules can depend on how the placement was arranged.

Why This Matters

Adoption processes can take many months, and sometimes well over a year, between a child being placed with prospective adoptive parents and the final adoption order being granted by the family court. Without this rule, adoptive families could face a substantial gap in Child Benefit entitlement during a period when they are, in every practical sense, the child’s primary carers. The rule recognises this reality and allows the claim to begin from the point the child actually comes to live with the prospective adopters.

Evidence Required

For adoption-related Child Benefit claims, you will eventually need to provide the original adoption certificate once the adoption is finalised — but you can begin your claim before this document exists, sending it on to HMRC separately once it becomes available, as covered in our detailed guide to Child Benefit eligibility rules.

Private and Step-Parent Adoptions

The “claim before completion” rule applies regardless of whether the adoption is being arranged through a local authority adoption agency, a voluntary adoption agency, or as a private/step-parent adoption (where, for example, a step-parent formally adopts their spouse’s child). In each case, the relevant trigger for Child Benefit eligibility is the date the child actually comes to live with the prospective adopter in the adoptive household, not the date any particular procedural milestone in the legal adoption process is reached. Families pursuing a step-parent adoption, who may already have been living with the child for an extended period before formally starting the adoption process, should note that their Child Benefit position is generally unaffected by the adoption itself if they were already the qualifying claimant beforehand — the adoption simply formalises a legal relationship that does not, by itself, change who was already entitled to claim.

Your Own Children While You Are Also a Foster Carer

A frequently asked and important question: does becoming a foster carer affect your ability to claim Child Benefit for your own children? The answer is no — these are entirely separate claims governed by entirely separate rules.

You can claim Child Benefit for your own children in the ordinary way, exactly as any other parent would, regardless of whether you are simultaneously fostering other children for whom you cannot claim Child Benefit (because of the local authority funding rule explained above). Your fostering activity and your status as a parent of your own children are assessed completely independently for Child Benefit purposes.

This sometimes causes confusion in larger blended households where a family has both their own birth children and one or more foster placements — the household may be claiming Child Benefit for the birth children while simultaneously receiving fostering allowances (not Child Benefit) for the foster children, with both income streams operating under entirely different rules and, as covered below, different tax treatment.

How Fostering Payments Actually Work

Understanding the structure of fostering payments helps explain why the Child Benefit exclusion exists and how it relates to other forms of support a fostering household might receive.

The Two Components of Fostering Payments

Fostering income typically has two distinct elements, paid together but conceptually separate:

The fostering allowance covers the child’s day-to-day needs, while the foster carer fee is the professional payment for time, care and commitment. Together, they form the total fostering income a carer receives — and it is specifically the maintenance/allowance element being paid by the council that triggers the Child Benefit exclusion, since that element is functionally serving the same purpose Child Benefit would otherwise serve.

Typical Payment Levels in 2026

Payment structures vary significantly between local authorities and independent fostering agencies, and by the carer’s skill/experience level, but illustrative figures from local authority schemes in 2026 show weekly allowances commonly ranging from roughly £280 to over £1,000 per week depending on the number of children placed, their ages, and the carer’s progression level, with additional payments for holidays, birthdays, religious festivals, school uniforms, and mileage layered on top of the base weekly figure.

Why Payment Levels Vary So Much

The wide range reflects several distinct factors operating together. First, most local authorities operate a tiered progression system — often labelled something like Level 1 through Level 4 — where carers move up through the tiers as they gain experience, undertake further training, and demonstrate the skills needed to manage increasingly complex placements, with payment increasing at each tier. Second, the number of children placed with a single household directly multiplies the weekly figure, since payments are made per child rather than as a flat household rate — a carer looking after three siblings receives substantially more than a carer looking after one child, reflecting the proportionally greater costs and demands involved. Third, specialist placement types — parent-and-child placements, where the carer supports a young parent and their baby together, emergency or short-notice placements, and placements for children with particularly complex needs — typically attract enhanced rates reflecting the additional skill and intensity required.

Independent fostering agencies, as distinct from local authority in-house fostering schemes, sometimes offer higher headline payment rates than local authorities for comparable placements, though the local authority remains the ultimate funder in most such arrangements (the agency acts as an intermediary providing additional training, support, and supervision), and the same Child Benefit exclusion rule applies regardless of whether the placement runs through a local authority directly or through an independent agency working on the local authority’s behalf.

Qualifying Care Relief: The Foster Carer Tax System

Although foster carers generally cannot claim Child Benefit for the children they foster, they benefit from a distinct and often very favourable tax treatment of their fostering income, known as Qualifying Care Relief (QCR).

How Qualifying Care Relief Works

All foster carers are required to register as self-employed with HMRC, since fostering income is treated as a form of self-employment for tax purposes. Foster carers can then benefit from Qualifying Care Relief, which allows them to receive certain payments tax-free up to a calculated threshold. The qualifying amount is made up of two parts: a fixed amount per household, plus an additional amount based on the number and ages of the children cared for.

2026/27 Qualifying Care Relief Figures

A worked example illustrates the scale of this relief: a carer looking after two foster children — one aged 8, one aged 13 — for a full tax year would have a total qualifying amount of £19,690 + £21,580 + £25,740 = £67,010, meaning their fostering income would need to exceed £67,010 in that year before any tax became due at all.

The Simplified Method

The relief is mandatory where it applies — carers cannot choose to calculate their fostering profit using ordinary self-employment expense rules instead. HMRC treats the carer as making neither a profit nor a loss where total receipts stay within the qualifying amount, meaning no Income Tax and no Class 4 National Insurance is due on the fostering income in those circumstances.

Carers still need to file a Self Assessment tax return each year and formally claim Qualifying Care Relief in the self-employment section, even where the result is that no tax is owed at all.

A Further Worked Example: Income Above the Qualifying Amount

Where a carer’s total fostering receipts exceed their qualifying amount, tax is due only on the excess, not on the full receipts. Consider a carer fostering one teenager for a complete tax year, with a qualifying amount of £19,690 (fixed) plus an age-related addition for the older child age band, bringing the total qualifying amount to roughly £41,270. If that carer’s total fostering receipts for the year were £45,000, the taxable profit using the simplified method would be calculated simply as receipts minus the qualifying amount: £45,000 − £41,270 = £3,730 in taxable profit. If the carer’s personal tax allowance is otherwise unused, this modest profit figure would likely result in no tax actually being payable in many cases, since it falls well within the standard personal allowance most taxpayers receive.

This illustrates why Qualifying Care Relief is often described as one of the most generous targeted tax reliefs in the UK system — a household fostering even a relatively high-income placement can frequently end up with no tax liability at all, while still building a full tax record through their Self Assessment filing.

What Counts as “Qualifying Care Receipts”

Qualifying care receipts include all income from a local authority, independent fostering provider, voluntary organisation, or social care scheme connected to providing care — both the maintenance/allowance element and the professional fee/reward element count together for the purposes of calculating whether receipts exceed the qualifying amount. Carers do not need to separate the two elements when applying Qualifying Care Relief; the relief applies to the combined total.

What Happens If You Don’t Use the Same Method Every Year

There are specific rules that apply if a carer does not use the same profit calculation method consistently from year to year — for example, switching between the simplified Qualifying Care Relief method and full profit/loss calculation in different tax years can affect what capital allowances are available in subsequent years. Carers considering departing from the simplified method in any given year, perhaps because they have significant allowable expenses that would produce a more favourable result under ordinary trading rules, should take specialist advice or consult HMRC’s detailed manual guidance before making that election, since the choice has knock-on consequences for later years.

Foster Carers and Self Assessment

The requirement to register as self-employed and file Self Assessment returns applies to foster carers regardless of whether Qualifying Care Relief reduces their tax bill to zero. You must still file a Self-Assessment tax return annually, even if you owe nothing.

Why This Still Matters Even With No Tax Due

Filing the return, even when no tax is owed, serves several purposes: it creates an official HMRC record of your fostering activity and income, which can be relevant evidence in other contexts (mortgage applications, other benefit assessments, or future disputes); it allows carers the opportunity to be treated as having paid voluntary Class 2 National Insurance contributions, protecting their state pension and other contributory benefit entitlements; and it keeps the carer compliant with their legal obligations, avoiding any risk of a failure-to-notify penalty even though the substantive tax liability is nil.

Record-Keeping Requirements

Foster carers should keep detailed records of their fostering payments and allowances for at least six years, covering both the gross payments received from the local authority or agency and any relevant expenses, even though the simplified Qualifying Care Relief method means most carers will not need to itemise individual expenses against their fostering income for tax purposes.

National Insurance, State Pension, and Home Responsibilities Protection

Voluntary National Insurance Contributions

Most foster carers will not need to pay National Insurance unless their taxable profit from fostering exceeds the relevant Class 4 threshold — which, given the generous Qualifying Care Relief amounts above, means most carers have no fostering income subject to NI at all. However, many choose to pay voluntary Class 2 National Insurance contributions specifically to protect their state pension and other contributory benefit entitlements, since fostering income that falls entirely within the tax-free Qualifying Care Relief threshold would not otherwise generate any NI record.

Home Responsibilities Protection for Foster Carers

For periods of fostering before 2010 (when Home Responsibilities Protection, or HRP, was the relevant mechanism, before being replaced for most purposes by NI credits), foster carers may be able to retrospectively apply for HRP to be added to their NI record. If you think Home Responsibilities Protection is missing from your National Insurance record relating to a period of caring, you can apply online or by post. You will need to send a copy of an up-to-date letter of confirmation from the local authority or fostering agency with your application, along with evidence showing that the allowance or benefit paid covered at least 48 weeks of each year you are claiming HRP for.

This is a valuable but often-overlooked route for long-term foster carers, particularly those who fostered extensively during periods before more recent NI credit systems were in place, since correcting historic NI record gaps can have a meaningful positive effect on eventual state pension entitlement.

Fostering and Universal Credit

A consistent and important point across multiple authoritative sources: fostering allowances are disregarded when calculating Universal Credit, meaning your fostering income does not reduce your UC award. This is sometimes described as fostering payments being “ignored” for means-tested benefit purposes.

What This Means in Practice

The fostering allowance you receive from your fostering agency or local authority is not treated as income when working out your eligibility for most welfare benefits — Universal Credit, Housing Benefit, and Council Tax Reduction included. This means a fostering household can potentially still qualify for these means-tested benefits based on their other circumstances, without their fostering income counting against them.

Becoming a Foster Carer Does Not Affect Council-Paid Benefits

Becoming a foster carer does not affect your eligibility for benefits paid by, or on behalf of, your local council in a general administrative sense — but you should always confirm your specific position with your fostering supervising social worker or a benefits adviser, since individual circumstances and the specific benefits involved can introduce nuances not captured by this general rule.

Disabled Foster Children: DLA, PIP, and Carer’s Allowance

While Child Benefit itself cannot generally be claimed for foster children in standard local authority placements, disability-related benefits operate under different rules and can often still be accessed.

Claiming on Behalf of a Disabled Foster Child

If your foster child is eligible for Disability Living Allowance (DLA) or Personal Independence Payment (PIP), you can claim this on their behalf. These benefits help cover additional disability-related costs arising from the child’s condition and are not affected by your fostering income — they exist on an entirely separate track from both Child Benefit and the standard fostering allowance, recognising that a disabled child’s needs go beyond what either of those payments is designed to cover.

Why This Distinction Exists

DLA and PIP are not “child maintenance” payments in the sense that triggers the Child Benefit exclusion — they are specifically targeted at the additional costs and care needs arising from disability, regardless of who is funding the child’s general accommodation and maintenance. This means a local authority foster carer caring for a disabled child can be in the position of receiving a fostering allowance (blocking Child Benefit) while simultaneously being able to claim DLA or PIP on the child’s behalf (unaffected by either the fostering allowance or the Child Benefit exclusion).

Carer’s Allowance Considerations

Where a foster carer is providing a substantial level of care connected to a child’s disability, Carer’s Allowance may also be relevant in some circumstances, though the interaction between Carer’s Allowance, fostering income, and disability benefits for the child involves several moving parts that are best checked with a specialist benefits adviser given the carer’s specific hours of care and the level of any other income.

Why Disability Benefits Are Particularly Valuable in a Fostering Context

For foster carers looking after a child with significant additional needs, DLA or PIP can make a material difference to the household’s ability to meet costs that go well beyond what the standard fostering allowance is designed to cover — specialist equipment, additional transport for medical appointments, adapted clothing, or the time cost of additional caring responsibilities that reduce a carer’s capacity to take on further placements or other income-generating activity. Because these benefits sit entirely outside the Child Benefit and fostering allowance framework, carers sometimes overlook them, particularly if they have become accustomed to thinking of the fostering allowance as the single source of child-related financial support in their household. Specifically asking your supervising social worker, or a specialist disability benefits adviser, whether a foster child’s needs might support a DLA or PIP claim is worth doing proactively rather than waiting for the question to be raised by someone else, since these benefits are not automatically triggered by the existence of a fostering placement and require a separate application process with their own evidential requirements.

When a Foster Child Turns 18: What Changes

Child Benefit, fostering allowances, and the broader support framework all undergo significant change once a young person in care turns 18, since the legal framework shifts from children’s services to adult/leaving care provisions.

The Transition at 18

Some young people continue to stay with their former foster carers after turning 18, often under “Staying Put” arrangements that many local authorities support. Once a young person turns 18, they become able to claim benefits in their own right — for example, Jobseeker’s Allowance, or Income Support if they remain in non-advanced education as a care leaver.

Staying Put Arrangements in More Detail

“Staying Put” is the policy framework that allows young people to remain living with their former foster carers beyond their 18th birthday, recognising that an abrupt transition to independent living at exactly 18 does not reflect how most young people actually move toward independence, whether in care or not. Local authorities are required to have a Staying Put policy and to provide financial support to former foster carers who agree to continue providing a home under these arrangements, though the specific level of support and the precise financial mechanics differ from the standard fostering allowance structure that applied before the young person turned 18, since the legal basis for the arrangement has fundamentally changed even though the day-to-day living situation may look very similar from the outside.

Housing and Council Tax Considerations

If the young person is receiving Income Support while in education as a care leaver, income-based Jobseeker’s Allowance, or is on a recognised training scheme, their continued presence in the former foster carer’s home will not normally affect any Housing Benefit or Council Tax Benefit the household receives until the young person reaches 25 — though the income the young person themselves receives may need to be factored into the household’s benefit calculations in other ways, depending on the specific arrangement and benefits involved, making it worthwhile to check the current position with the local authority or a benefits adviser at the point the young person turns 18 rather than assuming the pre-18 arrangements simply continue unchanged.

Leaving Care Support

Payments made under Leaving Care Act provisions for young people who have left foster care follow a different framework again, administered by the local authority’s leaving care team rather than through the standard fostering payment system, and are designed to support the transition to independent living rather than to replicate the earlier fostering allowance structure.

What Happens If You Claim Child Benefit by Mistake

Given the genuine complexity in this area — particularly around connected persons arrangements, the adoption transition period, and informal kinship care that later becomes formalised — it is possible for a carer to claim Child Benefit in circumstances where they were not actually entitled, or to continue receiving it after their circumstances changed in a way that ended their entitlement.

What to Do If You Realise This Has Happened

If you realise you have been claiming Child Benefit for a foster child in circumstances where the local authority was contributing to their maintenance, contact the Child Benefit Office promptly to report the change. Acting proactively to correct an overpayment, rather than waiting for HMRC to identify it through their own checks, generally leads to a more straightforward resolution and avoids any question of penalties for failing to report a relevant change in circumstances.

How This Connects to the Broader Appeals and Overpayment Framework

If HMRC subsequently seeks to recover an overpayment relating to a foster care arrangement, the general principles covered in our guide to the Child Benefit appeals process apply — including the right to dispute the amount of any overpayment and, in certain circumstances, whether you should be liable to repay it at all, particularly if the situation arose from a genuine misunderstanding about how the funding rules applied to your specific arrangement rather than any failure to report a change you were aware of.

Why Genuine Confusion Is Common — and Why It Matters for Any Dispute

Given everything covered in this guide — the distinction between formal and informal kinship arrangements, the special guardianship nuances, the adoption transition rules, and the fact that the determining factor is specifically about council funding rather than the carer’s relationship to the child — it should be clear that genuine, good-faith confusion about Child Benefit entitlement in fostering and kinship care contexts is common and understandable, not a sign of carelessness. This matters because, as covered in detail in our guide to Child Benefit appeals, a finding that a claimant had a reasonable excuse for an error, or that a change in circumstances was reported as promptly as could reasonably be expected given a genuinely ambiguous situation, can significantly affect both the existence and the recoverability of any resulting overpayment. Carers facing an overpayment demand connected to a change in their fostering or kinship care arrangement should not assume the debt is automatically and entirely their responsibility to repay in full without first understanding both the factual basis for HMRC’s calculation and their procedural rights to challenge it.

Practical Scenarios: Worked Examples

Scenario A: Standard Local Authority Foster Placement

Maria is an approved foster carer with her local authority, caring for an 11-year-old boy placed with her through the council’s fostering panel. She receives a weekly fostering allowance and professional fee from the council. She cannot claim Child Benefit for this child, because the council is funding his maintenance. She can claim Qualifying Care Relief on her fostering income for tax purposes, and her fostering payments do not affect any Universal Credit she may separately be entitled to.

Scenario B: Grandmother With an Informal Arrangement

Pat’s daughter is going through a difficult period and Pat has informally taken over day-to-day care of her grandson, with no social services involvement and no council payments of any kind. Pat can likely claim Child Benefit for her grandson under the standard “responsible for a child” rules, since no local authority funding is involved in this informal family arrangement.

Scenario C: The Same Family, After Social Services Becomes Involved

Six months later, social services becomes involved due to ongoing concerns, and Pat becomes a formally approved “connected persons” foster carer, with the council now paying her a fostering allowance for her grandson. Pat’s Child Benefit entitlement for her grandson now ends, because the funding source has changed — even though her day-to-day care of the child has not changed at all. She should notify HMRC of this change promptly.

Scenario D: Prospective Adopters

James and Priya have a child placed with them by an adoption agency, ahead of the formal adoption order being granted by the court (a process expected to take a further eight months). They can claim Child Benefit now, from the date the child came to live with them, without waiting for the adoption to be finalised.

Scenario E: Special Guardian

Tom became his niece’s special guardian under a Special Guardianship Order two years ago, following a family court process. The local authority provided a one-off special guardianship support payment at the time but does not make ongoing maintenance payments. Tom can likely claim Child Benefit for his niece, since there is no ongoing council funding of her maintenance — though he should confirm this with the Child Benefit Office given his specific support package.

Frequently Asked Questions

Can foster carers claim Child Benefit for foster children?

Generally no. You cannot claim Child Benefit for a child placed with you through standard local authority foster care, because the council’s fostering allowance already supports the child’s maintenance needs. The key test is whether the local council is paying anything toward the child’s accommodation or maintenance.

Can I claim Child Benefit for my own children if I am also a foster carer?

Yes. Your status as a foster carer for other children does not affect your right to claim Child Benefit for your own birth or adopted children, which is assessed entirely separately.

Can kinship carers or connected persons claim Child Benefit?

It depends on whether the local authority is funding the placement. An informal kinship arrangement with no council payment can generally claim Child Benefit. A formally approved “connected persons” foster placement with the council paying an allowance generally cannot.

Can special guardians claim Child Benefit?

Often yes, since special guardianship typically does not involve an ongoing local authority maintenance payment in the way that fostering does. The specific support package should be checked, as arrangements can vary between local authorities.

Can I claim Child Benefit while I am still in the process of adopting a child?

Yes. You can claim Child Benefit as soon as the child you are adopting comes to live with you — you do not need to wait until the adoption process is legally finalised.

Does fostering affect my Universal Credit?

No, in terms of the fostering allowance and professional fee themselves — these are disregarded when calculating Universal Credit. Other income, such as employment earnings unrelated to fostering, is still assessed normally.

Can I claim disability benefits for a disabled foster child?

Yes. Disability Living Allowance (DLA) and Personal Independence Payment (PIP) can be claimed on behalf of a disabled foster child, and these are not affected by either your fostering allowance or the general Child Benefit exclusion for foster children.

Do foster carers pay tax on their fostering income?

Often very little or none, due to Qualifying Care Relief, which provides a substantial tax-free threshold (£19,690 fixed amount plus additional amounts per child based on age, for 2026/27). Foster carers must still register as self-employed and file a Self Assessment return, even where no tax is ultimately due.

What happens to Child Benefit and fostering support when a young person turns 18?

Child Benefit is not relevant to a young person once they turn 18 in any case. Fostering allowances generally end at 18, though “Staying Put” arrangements and leaving care support may continue in a different form, and the young person becomes able to claim benefits such as Jobseeker’s Allowance or Income Support in their own right.

What should I do if I am unsure whether my arrangement qualifies for Child Benefit?

Contact the Child Benefit Office directly on 0300 200 3100 to clarify your specific position, particularly in connected persons, special guardianship, or partially council-funded arrangements where the position is not immediately obvious from the general rules.
