Who can get SSDI

You are entitled to SSDI while you are disabled and younger than full retirement age if all four of these are true:

• You are insured for disability. You worked long enough, and recently enough, under Social Security. The credits you need depend on your age; see the table below.20 C.F.R. § 404.130
• You have a disability as the law defines it. You cannot do any substantial gainful activity because of a medically determinable physical or mental impairment that is expected to result in death or has lasted, or is expected to last, at least 12 months.20 C.F.R. § 404.1505(a)
• You apply. Benefits are not automatic. Filing protects your right to back pay and your right to appeal.20 C.F.R. §§ 404.315(a)(2), 404.603
• You have served the waiting period. You have been disabled for 5 full consecutive months, unless no waiting period is required.20 C.F.R. § 404.315(a)(4)

There is no limit on your savings, your home or your spouse’s income for SSDI. That is the main difference from SSI.

How SSA decides you are disabled: the five steps

A state agency usually makes the medical decision for SSA. It follows the same five steps in order, and stops as soon as it can decide. 20 C.F.R. §§ 404.1503(a), 404.1520(a)(4)

1. 1Are you working at the substantial level? If your work is substantial gainful activity, SSA finds you not disabled, whatever your medical condition.
2. 2Is your impairment severe? It must significantly limit your ability to do basic work activities and meet the 12-month duration rule.
3. 3Does it meet or equal a listing? If it meets or equals one of the impairments in SSA’s listings (appendix 1) and the duration rule, SSA finds you disabled.
4. 4Can you still do your past work? SSA assesses what you can still do (your residual functional capacity) and compares it with your past relevant work: substantial work you did within the past five years.
5. 5Can you adjust to other work? SSA looks at that capacity together with your age, education and work experience. If you cannot adjust to other work, SSA finds you disabled.

Work credits: how many you need at your age

You earn up to 4 work credits a year. In 2026 you get one credit for each $1,890 of wages or self-employment income, and in 2027 for each $1,970. SSA calls a credit a quarter of coverage. 20 C.F.R. § 404.143(a) · Federal Register 2025-19763 and 2026-21796

To be insured for disability you need two things: enough credits in total (fully insured), and enough of them earned recently. The recent-work rule depends on your age when the disability began:

How the table is worked out: under 20 C.F.R. § 404.130(b) you need 20 credits in the 40 quarters ending with the quarter your disability began; before age 31, § 404.130(c) asks for credits in one-half of the quarters after the quarter you turned 21, and at least 6 in the last 12 quarters when that period is shorter than 12 quarters. Fully insured, under §§ 404.110(b) and 404.132, means 1 credit for each year after the year you turned 21 and before the year your disability began, never fewer than 6 or more than 40. The totals for ages 44 to 62 come from that count; SSA works out your exact quarters from your birth date and your earnings record. If you are statutorily blind, § 404.130(e) asks only that you are fully insured.

The 5-month waiting period, and back pay

• Five full months. SSDI is not paid for the first 5 full consecutive months of disability. The waiting period begins with a month in which you were both insured and disabled; if you became disabled on March 15, the first full month is April, and benefits can start with September.20 C.F.R. § 404.315(a)(4)
• The first month after the wait. Benefits begin with the first month after the waiting period that your application covers.20 C.F.R. § 404.316(a)
• Back pay, 12 months at most. If you apply late, SSA can pay benefits for up to 12 months immediately before the month you apply, but never for a month before the waiting period ends.20 C.F.R. § 404.621(a)(1)
• The wait cannot start too early. Your waiting period can begin no earlier than the 17th month before the month you apply, that is 17 months back, however long you were disabled before then. Waiting years to apply can cost months of benefits.20 C.F.R. § 404.315(a)(4)
• When there is no waiting period. If you were entitled to disability benefits at any time within 5 years of the month you became disabled again, or if you have ALS (amyotrophic lateral sclerosis) and SSA approved your application on or after July 23, 2020. The wait is then 0 months: benefits can start with the first full month of disability.20 C.F.R. § 404.315(a)(4)(i), § 404.315(a)(4)(ii)

How much SSDI pays

Your monthly SSDI benefit equals your primary insurance amount (PIA), worked out from your average indexed monthly earnings (AIME) over your working life (20 C.F.R. § 404.317). For a worker who first becomes eligible in 2026, the PIA is 90 percent of the first $1,286 of AIME, plus 32 percent of AIME between $1,286 and $7,749, plus 15 percent of AIME above $7,749. For 2027 the dollar amounts are $1,340 and $8,077. Federal Register 2025-19763 and 2026-21796

The benefit then rises each December with the cost-of-living increase: 2.8 percent for December 2025 and 3.6 percent for December 2026. Your spouse and children can also get benefits on your record, up to a family maximum. The estimate SSA keeps for you is in your Social Security Statement, in your my Social Security account at ssa.gov.

Working while you get SSDI: the earnings limits

Earnings over the substantial gainful activity (SGA) amount ordinarily show that a person can do substantial work: $1,690 a month in 2026 and $1,770 in 2027, or $2,830 and $2,950 if you are statutorily blind. SSA subtracts subsidized earnings and the reasonable cost of impairment-related work expenses before it compares. 20 C.F.R. § 404.1574(b) · Federal Register 2026-21796

• Trial work period: 9 months. Once you get SSDI, you can test your ability to work in as many as 9 months, not necessarily in a row, within a rolling 60-month period, and still get your full benefit. A month counts if you earn over $1,210 in 2026 or over $1,270 in 2027.20 C.F.R. § 404.1592
• Extended period of eligibility: 36 months. After the trial work period, a reentitlement period of 36 months follows. The first time you do substantial work, SSA pays that month and the next two; after those three months, no benefit is paid for a month of substantial work, and benefits restart without a new application for a month you do not.20 C.F.R. § 404.1592a
• Report your work. Tell SSA when you start or stop work and when your pay changes, so that each month is counted correctly.20 C.F.R. § 404.1592a(a)

When Medicare starts

Medicare hospital insurance begins with the 25th month in which you are entitled to disability benefits, so 24 months after your first month of SSDI. Earlier months of disability benefits can count toward the 25 in some cases. 42 C.F.R. § 406.12(a), § 406.12(b), § 406.12(d)(1)

The 25 months are counted from your first month of entitlement, which comes after the 5-month waiting period: from the start of a disability to Medicare is usually about two and a half years. Until Medicare starts, a low income may qualify you for Medicaid.

SSDI payment dates for 2026 and 2027

SSA assigns your payment day from the birthday of the worker whose record pays the benefit. Born on the 1st through the 10th: the second Wednesday of the month. Born on the 11th through the 20th: the third Wednesday. Born after the 20th: the fourth Wednesday. Everyone paid on a record where someone applied before May 1, 1997, or where a person also gets SSI, is paid on the 3rd of the month. When the day falls on a Saturday, Sunday or federal holiday, the payment comes on the first day before it that is not. 20 C.F.R. § 404.1807(b)(2), § 404.1807(c)(1), § 404.1807(c)(2)

SSDI or SSI, or both

You can get both when your SSDI is small: SSA counts Social Security benefits as unearned income for SSI (20 C.F.R. § 416.1121(a)), pays SSDI on the 3rd and SSI on the 1st of the month. See SSI: who qualifies and how much it pays.

Is Social Security disability taxable?

Sometimes. Federal income tax applies to part of your SSDI only when your other income plus one-half of your benefits is more than a base amount: $25,000 for most single filers and $32,000 on a joint return (zero if you are married, file separately and lived with your spouse during the year). Up to one-half of the benefits can then be taxed, and up to 85 percent once that total passes $34,000, or $44,000 on a joint return. 26 U.S.C. § 86(a), (c)

Many people whose only income is SSDI owe no federal tax on it. State rules differ.

How long SSDI lasts, and what happens at retirement age

• Reviews. SSA reviews whether you are still disabled: every 6 to 18 months if improvement is expected, at least once every 3 years if it cannot be predicted, and every 5 to 7 years if your disability is considered permanent.20 C.F.R. § 404.1590(d)
• When it ends. Benefits end with the second month after the month your disability ends, or the month before you die.20 C.F.R. § 404.316(b)
• At full retirement age. SSDI stops the month before you reach full retirement age and changes automatically into retirement benefits.20 C.F.R. § 404.316(b)(2)

How to apply for SSDI

1. 1Gather your records. The names, addresses and dates for every doctor, hospital and clinic; your medicines and tests; and the jobs you held in the past five years, with what each one required.
2. 2Apply to SSA. Online at ssa.gov, by phone at 1-800-772-1213 (TTY 1-800-325-0778), or at a local Social Security office. Apply as soon as you can: back pay reaches back at most 12 months.
3. 3The medical decision. SSA sends the medical part to your state’s disability agency, which may ask for more records or for an examination.
4. 4Read the decision and the date on it. If SSA says no, you have 60 days after you receive the notice to ask for reconsideration, and SSA presumes you received it 5 days after its date.

Do you need an SSDI lawyer? What one can charge

A lawyer or another representative can help with the application or an appeal, such as the hearing before a judge (see appeal a disability denial). Whoever it is, SSA decides what a representative may charge: a representative must not charge or receive any fee SSA has not authorized, or more than the amount it authorizes.

• Fee agreement: 25% of back pay, up to $9,200. With a written fee agreement, which SSA must approve, the fee cannot be more than 25% of your past-due benefits (back pay) or $9,200, whichever is less. The $9,200 limit took effect on November 30, 2024, and SSA publishes a notice in the Federal Register only when it raises the limit.POMS GN 03940.003 · 90 FR 19241
• Fee petition: SSA sets the amount. Without an approved fee agreement, the representative files a written request after the case is over, listing the services and the time spent on each. SSA weighs the services, the complexity of the case, the time spent, the results and the level of appeal, among other factors, and decides the fee.20 C.F.R. § 404.1725
• SSA pays the fee from your back pay. For an attorney or an eligible non-attorney, SSA pays the authorized fee straight from your past-due benefits: the lesser of 25% of them or the fee it set, minus an assessment charged to the representative. The representative may not make you repay that assessment.20 C.F.R. § 404.1730(b), (d)
• Free representation. If the representative waives the fee and any expenses in writing, you are not liable to pay a fee or expenses to them or anyone else. Legal aid offices can often help with disability claims for free.20 C.F.R. § 404.1720(e)(1)

Before you sign, ask: whether the agreement uses SSA's fee agreement limit; which expenses, such as copies of medical records, you will be asked to pay; and what happens to the fee if the case goes on to federal court.

Getting help

A lawyer or another representative can help with the application or an appeal, but may not charge or receive any fee that SSA has not authorized (20 C.F.R. § 404.1720(b)(3)). Legal aid offices can often help with disability claims for free.
