  • The 2026 SSI maximum is $994/month for individuals, $1,491/month for couples
  • The 2026 SSDI average is approximately $1,580/month; the maximum is $4,018/month
  • You can receive both SSI and SSDI at the same time — called “concurrent benefits”

What Is SSI?

Supplemental Security Income (SSI) is a federal program run by the Social Security Administration (SSA) that provides monthly cash payments to people who are:

  • Age 65 or older, OR
  • Blind, OR
  • Have a qualifying disability

…AND who have limited income and resources. SSI is a needs-based program — your financial situation is what determines eligibility, not your work history. Even someone who has never worked a day in their life can qualify for SSI if they meet the disability and financial criteria.

In 2026, SSI is funded entirely by general tax revenues — not Social Security payroll taxes. That’s a key distinction from SSDI.

What Is SSDI?

Social Security Disability Insurance (SSDI) is a federal insurance program that pays monthly benefits to workers who become disabled and can no longer work. The critical difference: you must have worked and paid Social Security taxes to qualify.

SSDI works like an insurance policy. Every paycheck you’ve ever received has had Social Security taxes withheld (6.2% of wages up to the taxable maximum). Those contributions earn you “work credits.” If you become disabled, SSDI pays out based on those credits.

In 2026, to earn one Social Security work credit you need to earn $1,810. You can earn a maximum of 4 credits per year. Most workers need 40 credits (10 years of work) to qualify for SSDI, but younger workers need fewer credits depending on their age when they become disabled.

SSI Eligibility Requirements 2026

To qualify for SSI in 2026, you must meet all of the following:

1. Disability, Blindness, or Age

You must be one of the following:

  • Age 65 or older (no disability required)
  • Legally blind (20/200 or less vision in the better eye with correction, or visual field of 20 degrees or less)
  • Have a medically determinable physical or mental impairment that prevents substantial work and has lasted or is expected to last at least 12 months, or result in death

2. Income Limits

In 2026, to qualify for SSI you must typically earn less than $2,073 per month in wages as a single person or less than $3,067 per month as a married couple. However, the SSA uses a complex formula that excludes certain income — the actual countable income limit is $994/month (the Federal Benefit Rate).

How income is counted:

  • The SSA disregards the first $20 of any income per month
  • For earned income (wages), the SSA also disregards the first $65, then half of the remainder
  • SNAP benefits, housing assistance, and most tax refunds are excluded entirely

3. Asset (Resource) Limits

The asset limits are fairly straightforward — you can’t have more than $2,000 in “resources” (assets) for a single person and $3,000 for a couple (not counting money in an ABLE account).

Excluded resources (do NOT count toward the limit):

  • Your primary home
  • One vehicle used for transportation
  • Household goods and personal effects
  • Life insurance with face value under $1,500
  • ABLE account funds
  • Burial funds up to $1,500

Important: The asset limits have remained unchanged for decades despite inflation. Advocacy organizations are pushing Congress to update these limits through the SSI Restoration Act, but no changes have passed as of March 2026.

4. Residency and Citizenship

  • Must reside in the 50 states, D.C., or Northern Mariana Islands (SSI is NOT available in Puerto Rico, Guam, American Samoa, or U.S. Virgin Islands)
  • Must be a U.S. citizen or a “qualified alien” meeting specific immigration criteria

SSDI Eligibility Requirements 2026

1. Work Credit Requirement

How many credits you need depends on your age when you become disabled:

Age When DisabledCredits NeededYears of Work Needed
Under 246 credits in the 3 years before disability1.5 years
24–31Credits for half the time since age 21Varies
31–4220 credits5 years
4422 credits5.5 years
5028 credits7 years
5436 credits9 years
6038 credits9.5 years
62 or older40 credits10 years

2. Disability Definition

The SSA uses the same definition for SSDI as for SSI: you must have a medically determinable impairment that prevents you from performing Substantial Gainful Activity (SGA) and has lasted or is expected to last 12+ months or result in death.

The SSA generally uses an earnings limit to determine if a person’s work activity is SGA, which for 2026 is $1,690 per month under SSI. For SSDI, the SGA threshold in 2026 is $1,620/month for non-blind individuals and $2,700/month for blind individuals.

3. No Income or Asset Limits for Initial Eligibility

Unlike SSI, SSDI has no income or asset limits to determine whether you qualify. Once approved, however, earning above the SGA threshold can affect your benefits (see Trial Work Period below).


Benefit Amounts: SSI vs. SSDI

SSI Benefit Amounts (2026)

For 2026, the Supplemental Security Income (SSI) Federal Benefit Rate is $994 per month for an eligible individual and $1,491 per month for an eligible couple.

Your actual SSI payment may be less if you have any countable income. The formula: Federal Benefit Rate − Countable Income = Your Monthly SSI Payment

Most states also offer a state supplemental payment on top of the federal amount. Arizona, Arkansas, Mississippi, North Dakota, Tennessee, and West Virginia do not offer supplements. States like California, Massachusetts, and New York have among the highest supplements.

SSDI Benefit Amounts (2026)

SSDI benefits are calculated based on your Average Indexed Monthly Earnings (AIME) — essentially your average career earnings, adjusted for inflation. The SSA applies a complex formula to your AIME to arrive at your Primary Insurance Amount (PIA).

Key 2026 SSDI figures:

  • Average SSDI benefit: ~$1,580/month
  • Maximum possible SSDI benefit: $4,018/month (requires very high career earnings)
  • 2026 COLA applied: 2.8% increase from 2025 levels

Can You Get Both SSI and SSDI?

Yes. Receiving both is called concurrent benefits and it’s more common than people realize. This happens when:

  • Your SSDI benefit is low (because your work history was limited or earnings were low)
  • Your SSDI benefit is below the SSI Federal Benefit Rate ($994)
  • You otherwise meet SSI’s financial eligibility requirements

In this case, SSI “tops up” your SSDI payment to bring you closer to the SSI maximum. For example: if your SSDI is $600/month and you meet all SSI criteria, you may receive an additional ~$394 in SSI (the difference, minus applicable income counting rules).


How to Apply

Applying for SSI

You cannot apply for SSI online (as of 2026). You must:

  1. Call SSA at 1-800-772-1213 to schedule an appointment, OR
  2. Visit your local Social Security office in person

Bring: proof of identity, Social Security card, proof of residency, bank account information, proof of income (all sources), proof of assets (bank statements, property), medical records documenting your disability or blindness.

Applying for SSDI

SSDI applications can be completed online at ssa.gov/apply or by phone at 1-800-772-1213.

Bring/have ready: Social Security number, birth certificate, proof of citizenship, work history (employers, dates, job duties), medical records including doctor names, hospital records, prescription list, and most recent W-2 or tax return.

Processing Times

  • Initial decision: 3–6 months on average
  • If denied and you appeal: 12–24 months for a hearing before an Administrative Law Judge
  • Apply as early as possible — your back pay (for SSDI) starts from your established disability onset date, not your application date

What Happens If You’re Denied

More than 60% of initial SSDI applications are denied. Being denied does not mean you don’t qualify. The appeals process has four levels:

  1. Reconsideration — request within 60 days of denial; a different SSA examiner reviews your case
  2. ALJ Hearing — if denied again, request a hearing before an Administrative Law Judge (most approvals happen here)
  3. Appeals Council — if the ALJ denies you, the Appeals Council reviews the decision
  4. Federal Court — last resort

Tip: Hiring a Social Security disability attorney or advocate significantly improves your odds at the ALJ hearing level. Most disability attorneys work on contingency — they only get paid if you win, and fees are capped by law at 25% of back pay or $7,200, whichever is less.


FAQ

How long does it take to get SSI or SSDI approved?

Initial decisions take 3–6 months on average. If you’re denied and appeal to the ALJ hearing level, expect 12–24 months. In total, many applicants wait 2+ years from application to final approval. Apply immediately — do not wait.


Can children qualify for SSI?

Yes. Children under 18 with a qualifying disability and limited family income and resources can receive SSI. The SSA evaluates the child’s disability differently from adults and also counts a portion of parents’ income when determining eligibility.


Does getting SSI or SSDI affect my family members’ benefits?

SSI is an individual benefit and does not directly affect other family members. SSDI, however, can generate auxiliary benefits for your spouse and dependent children — potentially worth hundreds of additional dollars per month.


Can I work while receiving SSI or SSDI?

Yes, both programs have work incentives designed to encourage employment. For SSDI, the Trial Work Period allows you to test your ability to work for up to 9 months without losing benefits. For SSI, the earned income exclusions mean working part-time usually reduces your benefit by less than you earn.


What’s the difference between SSDI and Social Security retirement?

Both are paid from the same Social Security trust fund and calculated using similar formulas. SSDI is for workers who become disabled before retirement age. When you reach full retirement age (66–67, depending on birth year), your SSDI automatically converts to Social Security retirement benefits — usually at the same payment amount.
