Start a Social Security Disability Claim

A social security disability claim does not come with a filing date printed on the diagnosis. Social Security still wants it in as soon as you become disabled. The order on its own pages is apply, show that you cannot do substantial work, then wait for a medical decision.

Apply as soon as you cannot work

The SSA apply page says to apply as soon as you become disabled. You can file online or by calling 1-800-772-1213 between 8:00 a.m. and 7:00 p.m. A representative there can set an appointment if you cannot finish the application on the website.

Do not wait for a perfect folder. The SSA-16 page says not to delay because you do not have every document. Social Security will help you get many of them. Photocopies of W-2s, self-employment returns, and medical records are accepted. It still needs to see the original of most other proofs, such as a birth certificate, and it returns those.

If you already started an application and stopped, the apply page lets you finish with a re-entry number.

What Social Security means by disability

This is not a partial-disability program and it is not short-term sick pay. The eligibility page says Social Security pays only for total disability. All three of these have to be true:

• You cannot do work at the substantial gainful activity level because of the condition.
• You cannot do the work you did before, or adjust to other work, because of the condition.
• The condition has lasted or is expected to last at least 12 consecutive months, or to result in death.

In 2026, substantial gainful activity is $1,690 a month, or $2,830 if you are blind under Social Security's rules. If you are working and earning above that, Social Security generally will not find you disabled. Can I work while I apply for SSDI? covers the 2026 earnings numbers in more detail.

Work credits

SSDI is insurance you already paid for through Social Security tax. Credits are based on yearly wages or self-employment income. You can earn up to four credits a year. In 2026, one credit is $1,890, so $7,560 covers all four for the year.

How many you need depends on your age when the disability begins. The usual rule for adults is 40 credits, with 20 earned in the last 10 years ending with the year the disability begins. Social Security calls that the 20/40 Rule. Younger workers can qualify with fewer credits. The same page says that if you stop working under Social Security today, you may later fall short of the recent-work test even if you once had enough.

You can see whether you have enough work history by signing in at SSA.gov and looking under More Benefits, as the Who can get Disability page describes.

If the work credits are not there, SSI is the program that does not require them.

SSDI, SSI, or both

Social Security runs two disability programs. The adult medical standard is generally the same. The money and the other rules are not.

SSDI is paid from the disability trust fund and is based on your covered earnings. SSI is paid from general tax revenue and is for people with limited income and resources who are 65 or older, blind, or have a qualifying disability. You can apply for both. Social Security calls that concurrent.

On SSDI, there is usually a five-month waiting period. Payments do not begin before the sixth full month after the date Social Security finds your disability began. There is no waiting period if the disability is amyotrophic lateral sclerosis (ALS) and you are approved on or after July 23, 2020. SSI disability payments, when you qualify, start with the first full month after you file, or later if that is when you become eligible.

Social Security may also pay SSDI for as many as 12 months before the date you filed, if it finds you were disabled during that time and you meet the other rules.

Medicare for an SSDI recipient generally starts after 24 months of benefits. SSI recipients in most states can get Medicaid. The Red Book overview is the table that puts those side by side.

What to have ready

The SSA-16 list is long because the application is long. The pieces that come up first:

• The date you became unable to work, and whether you are still unable to work.
• Your doctors, clinics, tests, and an Adult Disability Report that describes the conditions and your work history.
• Medical records you already have. You do not have to wait for the rest.
• Last year's W-2s or self-employment tax returns.
• Proof of any workers' compensation or similar benefits.
• Names and dates for a spouse, former spouses, and unmarried children who might qualify on your record.

Keep Social Security numbers off this website. The form here never asks for one.

How Social Security decides

If you have enough work, Social Security uses five questions. The first one happens in its own offices: are you working above the 2026 earnings limit? If you are not, the file goes to Disability Determination Services in your state for the medical steps.

Those steps ask whether the condition is severe, whether it matches or equals a listing in Social Security's list of disabling conditions, whether you can do work you did before, and whether you can do any other work. Age, education, and transferable skills come in at that last step.

Two faster paths exist for some claims. Compassionate Allowances cover certain diagnoses that usually qualify once they are confirmed, including acute leukemia, ALS, and pancreatic cancer. Quick Disability Determinations use computer screening to find claims with a high probability of allowance. Neither path is something a website can promise.

How long an SSDI application takes separates the five-month waiting period from the time it takes to get a decision.

After a decision

A yes on SSDI still runs through the waiting period, unless an exception such as ALS applies. Benefits usually continue until you can work again on a regular basis. If you are still on SSDI when you reach full retirement age, the disability benefit converts to a retirement benefit in the same amount.

A no is not the end of the claim. You can ask for reconsideration within 60 days of when you receive the notice. If that is also a no, you can ask for a hearing with an administrative law judge, again within 60 days. What happens if Social Security denies my claim walks through those deadlines.

Where a representative fits

You can file every step yourself. If you want someone to file, gather records, or appear at a hearing, you appoint them with Form SSA-1696. The representative does not have to be a lawyer, but they do have to meet Social Security's rules, and Social Security has to approve any fee. How to choose a disability representative is the checklist for that call, including the partner who may call you through this site.
