HMRC and Side Hustles 2025/26 - The £1,000 Trading Allowance, Platform Reporting Rules & What You Must Declare
Quick Summary: 47% of UK adults have a side hustle. From January 2025, every platform — eBay, Vinted, Airbnb, Etsy, Deliveroo, Fiverr — is automatically sending your earnings to HMRC. There is no “side hustle tax” — it’s just regular income tax. But the rules are frequently misunderstood. This guide explains exactly what’s taxable, what’s not, when you must register, and how to pay the least tax legally possible.

1. The “Side Hustle Tax” Myth: What Actually Changed in 2025 {#myth}
There is no new “side hustle tax.” Headlines about “HMRC taxing your Vinted sales” and “eBay side hustle crackdown” fundamentally misrepresent what happened in January 2025.
What actually changed:
Data sharing became mandatory. From 1 January 2024, digital platforms operating in the UK were required to collect seller data and report it to HMRC. The first reports arrived with HMRC in January 2025. Platforms including eBay, Vinted, Etsy, Airbnb, Uber, Deliveroo, Fiverr, Upwork, and OnlyFans now automatically submit annual reports of your earnings to HMRC.
HMRC’s visibility expanded dramatically. Previously, many side hustlers’ income was invisible to HMRC. Now it isn’t. This is not a new tax — it’s new enforcement capability.
Income that was always taxable is now harder to hide. If you earned £5,000 on Etsy and never declared it, that was always illegal. HMRC now has evidence of it without needing to investigate.
┌──────────────────────────────────────────────────────────────────┐│ THE REAL CHANGE: HMRC'S DATA PIPELINE 2025 ││ ││ Before January 2025: ││ Your eBay sales → eBay → [data gap] → HMRC sees nothing ││ ││ From January 2025: ││ Your eBay sales → eBay → Annual report → HMRC cross-checks ││ against your tax record → flags if not declared ││ ││ Platforms currently reporting to HMRC: ││ eBay, Vinted, Etsy, Depop, Amazon Marketplace, Airbnb, ││ Booking.com, Uber, Deliveroo, Fiverr, Upwork, OnlyFans, ││ YouTube (monetised), and many more ││ ││ Reporting trigger thresholds (for platform to report): ││ Goods: 30+ transactions OR €2,000+ in the year ││ Services: No threshold — all service income reported │└──────────────────────────────────────────────────────────────────┘
This is part of the OECD’s DAC7 framework — a global agreement requiring digital platforms to share income data across participating tax authorities. HMRC can also share UK seller data with overseas tax authorities and vice versa.

2. How HMRC Now Automatically Knows About Your Earnings {#how-hmrc-knows}
The platform reporting process works like this:
Step 1: At year end, each qualifying platform submits a report to HMRC listing every seller/earner who met the reporting threshold — name, address, NI number, bank account, and total earnings.
Step 2: HMRC’s systems cross-reference this data against tax records. If you declared the income — either through Self Assessment or via the trading allowance — no action is taken.
Step 3: If HMRC identifies income that wasn’t declared, they may:
- Adjust your tax code to collect the tax through PAYE
- Issue a Simple Assessment letter
- Open a formal compliance investigation
The “30 transactions or €2,000” threshold:
The platform reporting rule for goods (eBay, Vinted, Etsy) is triggered when you make 30+ transactions OR earn €2,000+ in the year. Below this, platforms are not required to report — but HMRC can still request data on specific sellers.
For services (Airbnb, Uber, Deliveroo, Fiverr), there is effectively no minimum threshold — all income is reportable. The reasoning: it’s almost always trading income, not personal asset disposal.
3. The £1,000 Trading Allowance: Your First Line of Defence {#trading-allowance}
The trading allowance is a flat £1,000 annual exemption from income tax on trading and miscellaneous income. It is your most important tool if you earn money from side activities.
Key rules:
┌──────────────────────────────────────────────────────────────────┐│ THE £1,000 TRADING ALLOWANCE: RULES ││ ││ Annual exemption: £1,000 gross income per person ││ Applies to: All self-employment/trading income ││ Per activity? NO — £1,000 total, all combined ││ Pro-rated? NO — full £1,000 even for part year ││ Separate from: Employment income (no overlap) ││ ISA equivalent? No — just exempts from declaring ││ ││ If gross income ≤ £1,000: No Self Assessment needed* ││ No income tax ││ No National Insurance ││ ││ If gross income > £1,000: Choose: ││ Option A: Deduct £1,000 allowance from gross, pay tax on rest││ Option B: Deduct actual expenses, pay tax on profit ││ Pick whichever gives lower taxable amount ││ ││ *Unless HMRC has issued you a notice to file SA │└──────────────────────────────────────────────────────────────────┘
The allowance is per person, not per platform:
If you earn £600 on Vinted and £600 on Etsy, your total trading income is £1,200 — above the £1,000 allowance. You cannot apply £1,000 to each platform. It’s one allowance across all activities.
Trading allowance vs actual expenses:
If your income is, say, £4,000 but your expenses are £3,200, your actual profit is only £800. Claiming actual expenses (£3,200) is better than the trading allowance (£1,000):
- Actual expenses route: taxable profit = £4,000 - £3,200 = £800
- Trading allowance route: taxable profit = £4,000 - £1,000 = £3,000
Always calculate both options.
4. What Counts as Taxable Trading Income {#taxable}
Trading income is income from:
- Regularly selling goods with the intention of making a profit (not one-off clearouts)
- Providing services through any platform
- Making items to sell (crafts, art, baked goods)
- Renting out property or assets
- Driving, delivering, tutoring, freelancing
- Creating content for money (YouTube ads, brand deals, subscriptions)
The key test is: Are you trading?
HMRC’s “badges of trade” test determines whether an activity is a business or personal:
┌──────────────────────────────────────────────────────────────────┐│ HMRC'S BADGES OF TRADE: THE TEST ││ ││ Factor Trading (likely taxable) ││ ────────────────────────────────────────────────────────────── ││ Profit motive? Yes → trading indicator ││ Regularity? Frequent, regular activity → trading ││ Nature of asset? Bought to resell, not for personal use ││ Volume? Large quantities → trading ││ Supplementary work? Repaired/improved before selling → trading││ How acquired? Bought for resale → trading ││ Method of sale? Organised, systematic → trading ││ ││ Not trading: One-off, personal items, no profit intent ││ Grey area: Occasional flipping, hobby income │└──────────────────────────────────────────────────────────────────┘
5. What Is NOT Taxable: Selling Personal Items {#not-taxable}
Selling your own personal possessions at a loss or for no profit is not taxable income. This is the most important fact that news headlines about “side hustle taxes” routinely obscure.
Not taxable:
- Selling old clothes, books, furniture, electronics you bought for personal use
- Car boot sales of household items
- Clearing out your attic
- Selling items for less than you paid for them
The principle: if there’s no profit, there’s no income to tax.
The complication: Capital Gains Tax on high-value items
If you sell a single personal item (other than your car or personal goods covered by the chattels exemption) for over £6,000, Capital Gains Tax may apply to any gain. This affects rare collectibles, artwork, jewellery, and similar assets — not typical second-hand clothes or household goods.
The Vinted question:
Selling your own wardrobe on Vinted is not trading — even if you do it regularly, as long as you’re selling for less than you paid and not buying items to resell. The moment you start buying clothes cheaply and selling for profit, you’re trading.

┌──────────────────────────────────────────────────────────────────┐│ PLATFORM-BY-PLATFORM HMRC TAX GUIDE 2025/26 ││ ││ Platform Activity Likely Treatment ││ ────────────────────────────────────────────────────────────── ││ Vinted/Depop Sell own clothes NOT taxable (personal) ││ Vinted/Depop Buy to resell Trading income (taxable) ││ eBay Sell old items NOT taxable (personal) ││ eBay Regular reselling Trading income (taxable) ││ Etsy Sell handmade Trading income (taxable) ││ Airbnb Rent room Property income (use £1k PA) ││ Airbnb Rent whole home Property income (taxable) ││ Deliveroo Food delivery Trading income (taxable) ││ Uber Taxi/private hire Trading income (taxable) ││ Fiverr/Upwork Freelance services Trading income (taxable) ││ YouTube Ad revenue Trading income (taxable) ││ OnlyFans Subscriptions Trading income (taxable) ││ TaskRabbit Odd jobs Trading income (taxable) ││ Rover Pet sitting Trading income (taxable) │└──────────────────────────────────────────────────────────────────┘
Airbnb: Rent a Room Relief
If you rent out a room in your own home (not a separate property), you can claim the Rent a Room Relief of £7,500/year tax-free. This is separate from and more generous than the £1,000 property allowance. Income above £7,500 is taxable.
7. When You Must Register for Self Assessment {#register}
┌──────────────────────────────────────────────────────────────────┐│ SIDE HUSTLE: WHEN SELF ASSESSMENT REGISTRATION ││ IS REQUIRED ││ ││ Situation Must Register? ││ ────────────────────────────────────────────────────────────── ││ Gross side income ≤ £1,000 No (trading allowance) ││ Gross > £1,000, profit > £0 Yes ││ Gross > £1,000, profit < £0 Technically no ││ (but keep records) ││ HMRC issues a "notice to file" Yes, regardless ││ Foreign platform income Yes ││ Total income incl. side hustle > £100k Yes ││ ││ Registration deadline: 5 October following the tax year end ││ Example: 2025/26 income → register by 5 October 2026 ││ ││ Register at: gov.uk/register-for-self-assessment ││ Form CWF1 (new self-employed) │└──────────────────────────────────────────────────────────────────┘
The 5 October deadline is firm: Even if you haven’t calculated your tax bill yet, you must register by 5 October if you’ll have a Self Assessment liability. Late registration can trigger penalties even if you subsequently file and pay on time.
8. How to Calculate Your Side Hustle Profit {#calculate}
Step 1: Identify your gross trading income
Add up all income from all side activities in the tax year (6 April to 5 April). Include all platform payments received, regardless of whether they’ve cleared to your bank yet.
Step 2: Apply the trading allowance test
If gross income ≤ £1,000: stop. No further action needed (unless HMRC issues a notice).
Step 3: Compare allowance vs actual expenses
┌──────────────────────────────────────────────────────────────────┐│ SIDE HUSTLE PROFIT CALCULATION: EXAMPLE ││ ││ Freelance web designer, 2025/26 ││ Gross income: £6,500 ││ ││ Option A (Trading Allowance): ││ Taxable profit: £6,500 - £1,000 = £5,500 ││ ││ Option B (Actual Expenses): ││ Software subscriptions: £600 ││ Home office (proportion): £480 ││ Professional training: £350 ││ Marketing/website costs: £200 ││ Total expenses: £1,630 ││ Taxable profit: £6,500 - £1,630 = £4,870 ││ ││ Best option: Option B (actual expenses) → lower tax ││ Tax saving vs Option A: £5,500 - £4,870 = £630 × 20% = £126 │└──────────────────────────────────────────────────────────────────┘
Step 4: Combine with other income for overall tax position
Your side hustle profit sits on top of any employment income. Together, they determine your marginal tax rate.
9. Allowable Side Hustle Expenses {#expenses}
If claiming actual expenses rather than the trading allowance, keep receipts for everything business-related:
- Materials and stock — anything you buy to make or resell
- Postage and packaging — for goods sold online
- Platform fees — eBay, Etsy, PayPal, and similar selling fees
- Home office proportion — if working from home, a proportion of broadband, heating, electricity
- Equipment — camera, tools, laptop (business proportion)
- Software — editing tools, accounting software, design apps
- Marketing — advertising, social media promotion
- Professional subscriptions — memberships relevant to your trade
- Training — courses to develop your side hustle skills
- Travel — business mileage at 45p/mile (first 10,000 miles)
- Bank charges — for a dedicated business account
What you cannot deduct:
- Personal expenses (even if you use the same phone for business)
- Client entertainment
- Fines and penalties
- Your own salary or drawings
10. National Insurance for Side Hustlers {#ni}
Self-employed people pay National Insurance in addition to income tax:
┌──────────────────────────────────────────────────────────────────┐│ NATIONAL INSURANCE: SIDE HUSTLERS 2025/26 ││ ││ Class 2 NI: ││ Rate: £3.45/week (2025/26) if profit > £12,570 ││ Annual cost: £179.40 ││ Paid via: Self Assessment return ││ ││ Class 4 NI: ││ 9% on profits between £12,570 and £50,270 ││ 2% on profits above £50,270 ││ Paid via: Self Assessment return ││ ││ If side hustle profit < £12,570: ││ No Class 2 or Class 4 NI ││ ││ Already employed (paying Class 1 NI): ││ Still owe Class 4 on self-employment profit if above threshold ││ Class 2 may be waived — check with HMRC │└──────────────────────────────────────────────────────────────────┘
11. The Property Allowance: Airbnb and Short-Term Lets {#property}
The property allowance is a separate £1,000 exemption specifically for income from property — including Airbnb, renting a driveway, storage space, or garden.
Key rules:
- £1,000/year tax-free property income (gross, before expenses)
- Separate from the £1,000 trading allowance — you can use both
- If property income exceeds £1,000: choose actual expenses or the £1,000 allowance
- Rent a Room Relief (£7,500) is available instead of property allowance for live-in hosts
Airbnb 2025 tax example:
┌──────────────────────────────────────────────────────────────────┐│ AIRBNB INCOME: TAX CALCULATION EXAMPLE ││ ││ Scenario: Own home, rent out spare room via Airbnb ││ Annual Airbnb income: £6,000 ││ ││ Option A (Property Allowance): ││ Taxable: £6,000 - £1,000 = £5,000 ││ ││ Option B (Rent a Room Relief — live-in host): ││ Taxable: £6,000 - £7,500 = £0 (under threshold) ││ Tax owed: £0 ✓ ││ ││ Scenario: Entire property let (not your home), income £8,000 ││ Option A (Property Allowance): ││ Taxable: £8,000 - £1,000 = £7,000 ││ Option B (Actual expenses): ││ Cleaning, insurance, depreciation: £2,200 ││ Taxable: £8,000 - £2,200 = £5,800 ││ Best: Option B │└─── ───────────────────────────────────────────────────────────────┘
12. Making Tax Digital: What’s Coming for Side Hustlers {#mtd}
Making Tax Digital for Income Tax (MTD ITSA) fundamentally changes how self-employed people and landlords report income:
- From April 2026: Mandatory quarterly digital submissions for self-employed people and landlords with gross income above £50,000
- From April 2027: Threshold drops to £30,000
- From April 2028: Expected to drop to £20,000 (subject to confirmation)
What this means for side hustlers:
If your side hustle gross income exceeds the MTD threshold, you’ll need to:
- Use HMRC-recognised accounting software (Xero, QuickBooks, FreeAgent, etc.)
- Submit quarterly summary updates to HMRC (instead of one annual return)
- File a final declaration at year end
For most casual side hustlers earning under £30,000, MTD ITSA won’t apply until at least 2027. But if you’re growing, plan ahead.
13. Penalties for Non-Declaration {#penalties}
With platform data now flowing automatically to HMRC, non-declaration is increasingly risky:
┌──────────────────────────────────────────────────────────────────┐│ HMRC PENALTIES FOR UNDECLARED SIDE INCOME ││ ││ Behaviour Penalty Range ││ ────────────────────────────────────────────────────────────── ││ Innocent error (prompted) 0–30% of tax owed ││ Careless error (prompted) 15–30% ││ Deliberate non-disclosure 20–70% ││ Deliberate and concealed 30–100% ││ Offshore evasion Up to 200% ││ ││ HMRC's "Let Property Campaign" and "Help for Hustlers" ││ offer reduced penalties for voluntary disclosure ││ ││ Best approach: If you've had unreported side income in prior ││ years, make a voluntary disclosure before HMRC contacts you. ││ Penalties are substantially lower when you come forward first. │└──────────────────────────────────────────────────────────────────┘
14. Practical 4-Step Compliance Checklist {#checklist}
┌──────────────────────────────────────────────────────────────────┐│ SIDE HUSTLE TAX COMPLIANCE: 4-STEP CHECKLIST ││ ││ Step 1: Total your gross side income for the tax year ││ ☐ Add all platform payments (eBay, Vinted, Etsy, Airbnb etc.) ││ ☐ Include cash payments, bank transfers, any other income ││ ││ Step 2: Apply the trading/property allowance test ││ ☐ Is total below £1,000? → No tax, no registration needed ││ ☐ Over £1,000? → Move to Step 3 ││ ││ Step 3: Calculate your taxable profit ││ ☐ Trading allowance (£1,000) vs actual expenses — pick best ││ ☐ Identify all deductible expenses and keep receipts ││ ││ Step 4: Register and file (if profit > £0 and income > £1,000)││ ☐ Register by 5 October (year after activity) ││ ☐ File Self Assessment return by 31 January ││ ☐ Pay tax by 31 January (+ set up POA if bill > £1,000) │└──────────────────────────────────────────────────────────────────┘
15. Frequently Asked Questions {#faq}
Do I have to pay tax on Vinted sales?
Only if you’re trading — buying items to resell for profit. Selling your own personal clothes and items for less than you paid is not taxable. If you regularly buy cheap and sell for a profit, that’s trading and is taxable above £1,000.
I earn £800 from Etsy selling handmade crafts. Do I owe tax?
No — under £1,000 is covered by the trading allowance. You don’t need to register or file a Self Assessment return just for this, as long as you have no other untaxed income. Keep records in case HMRC asks.
HMRC has my platform data. Does that mean I’ll automatically get a tax bill?
Not necessarily. Platform data is used to cross-check against your records. If you’re within the trading allowance or have declared your income, there’s nothing to worry about. If HMRC finds a discrepancy, they may write to you — but this is an opportunity to explain or correct your records, not an automatic fine.
I have both a job AND a side hustle. How is my tax calculated?
Your side hustle profit is added to your employment income. Together, they determine your total taxable income and marginal rate. If the combined total is under £50,270, you pay 20% on the side hustle profit. Above that, 40%.
Can I claim pension contributions to reduce my side hustle tax?
Yes. Pension contributions reduce your adjusted net income, potentially keeping you in a lower tax band. This is a legitimate and common tax-saving strategy for sole traders and the self-employed.
