What You Actually Have to Do

Getting onto SSDI requires three concrete things: you must have worked long enough to earn work credits, you must have a medical condition that meets Social Security's definition of disability, and you must file a claim. Social Security does not reach out to you. You file the claim yourself, either online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. The process takes months—usually four to six months for an initial decision, sometimes longer if you are denied and file an appeal.

The work credit requirement depends on your age. If you are under 24, you need only six credits earned in the three years before you became disabled. If you are 24 to 31, you need credits equal to half the quarters since you turned 21. If you are 31 or older, you need 40 credits total, with at least 20 earned in the ten years before you became disabled. You earn one credit for every $1,730 of wages you report (in 2024; this amount changes yearly). You can earn up to four credits per year, so the 40-credit requirement takes a minimum of ten years of work.

Key Takeaways

  • You must file a claim yourself through ssa.gov, by phone, or at your local Social Security office—Social Security will not contact you.
  • Your medical condition must meet Social Security's definition of disability, which is stricter than most people's everyday use of the word and requires that you cannot do substantial work for at least 12 months.
  • You need a certain number of work credits based on your age, and you must have earned them recently enough that Social Security considers them current.
  • The initial decision usually takes four to six months, and if you are denied, you can appeal at multiple stages before a judge hears your case.
  • You do not need a lawyer to file, but many people hire one after a denial because the appeal process is complex.

How Social Security Defines Disability

Social Security's definition is narrower than you might expect. You must have a medical condition—physical, mental, or both—that prevents you from doing substantial work. "Substantial work" means earning more than a set monthly amount; in 2024, that threshold is $1,550 per month. If you can earn that much, Social Security considers you not disabled, even if you have a serious condition.

The condition must be expected to last at least 12 months or result in death. A temporary illness or injury, no matter how severe, does not may have access to. Social Security also looks at whether you can do any other work that exists in the national economy, not just your old job. If you were a carpenter but cannot do that work anymore, Social Security asks whether you could do sedentary office work instead. If the answer is yes, you will be denied.

Social Security uses a five-step process to evaluate your claim. First, they check whether you are working and earning substantial income. Second, they determine whether your condition is severe enough to interfere with basic work activities. Third, they compare your condition to conditions listed in Social Security's medical guide, called the Blue Book. If your condition matches a listing, you may be approved without further review. Fourth, if your condition does not match a listing, they assess whether you can do your past work. Fifth, they assess whether you can do any other work.

What Medical Evidence You Need

Social Security makes its decision based on medical records, not on your word alone. You need documentation from a doctor, psychiatrist, or other licensed medical professional who has examined you. Records should include diagnoses, test results, treatment history, and how your condition affects your ability to work. If you have been hospitalized, had surgery, or received ongoing treatment, those records carry more weight than a single office visit.

If you do not have recent medical records, Social Security may order a consultative exam—a one-time appointment with a doctor they choose and pay for. This exam is not a full evaluation; it is meant to fill gaps in the evidence you have already submitted. You cannot rely on a consultative exam alone to prove your case. You should gather your own medical records before you file, or as soon as possible after filing.

Mental health conditions require the same documentation as physical ones. You need records from a psychiatrist or licensed therapist showing diagnosis, treatment, and functional limitations. Social Security often denies mental health claims because the applicant has no recent treatment records. If you have stopped seeing a provider because you cannot afford it, explain that in your claim and ask about low-cost or free mental health services in your area.

The Filing Process Step by Step

Start by gathering documents: your Social Security card, birth certificate, proof of citizenship or legal residency, and a list of your doctors and hospitals. You will also need your work history for the past 15 years, including job titles and dates. Have your medical records ready or know where to get them.

File online at ssa.gov/applyfordisability if you prefer to do it yourself. The online process takes about 20 minutes and you can save your progress and return later. You can also call 1-800-772-1213 Monday through Friday, 7 a.m. to 7 p.m. your local time, and a representative will help you file over the phone. Or visit your local Social Security office in person; you can find the address at ssa.gov/locator.

After you file, Social Security sends your claim to your state's Disability information Services (DDS) office. DDS is a separate agency that makes the medical decision. They will request your medical records from your doctors and hospitals. This can take weeks. If records are missing, DDS may contact you or your doctors to ask for them. You can speed this up by sending records yourself.

Once DDS has reviewed everything, they send their decision back to Social Security. Social Security then notifies you by mail. If you are approved, you will receive a notice saying when your benefits start. If you are denied, the notice will explain why and tell you how to appeal.

What Happens If You Are Denied

Most people are denied on their first process. This does not mean your claim is hopeless. You have the right to appeal, and many people are approved on appeal. You have 60 days from the date on your denial notice to request reconsideration. Do not wait; if you miss the important date, you have to start over with a new process.

Reconsideration means a different DDS examiner reviews your case from scratch. You can submit new medical evidence at this stage. If you were denied because your medical records were incomplete, this is your chance to send the missing pieces. Many denials are reversed at reconsideration straightforward because the second examiner has better or more complete information.

If reconsideration is denied, you can request a hearing before an administrative law judge (ALJ). This is where many cases are won. The judge reviews the entire file and can ask you and your doctors questions. You can bring a lawyer or representative to the hearing. Many disability lawyers work on contingency, meaning they take a percentage of your back pay if you win, and nothing if you lose. The contingency fee is capped at 25 percent of back pay or $7,200, whichever is less.

Work Credits and Timing

Work credits must be recent enough to count. If you are 31 or older, you need 40 credits total, but at least 20 of those must have been earned in the ten years before you became disabled. This means if you worked steadily for ten years and then stopped, you still have current credits. But if you worked ten years ago and have not worked since, those old credits do not help you meet the recency requirement.

You earn credits based on wages reported to Social Security, not on how many hours you worked. Self-employment income counts the same way as wages. If you worked part-time or had gaps in employment, you may still have enough credits if you earned enough in the years you did work. You can check your work history and credits anytime at ssa.gov/myaccount.

When You Might Not Need to File Yourself

If you are already receiving retirement benefits or survivor benefits from Social Security, you do not file a separate disability claim. Instead, you can ask Social Security to convert your current benefit to a disability benefit. This is called a "deemed filing" and happens automatically in some cases. Contact Social Security to ask whether this applies to you.

If you are a widow, widower, or adult child of someone who received or was may have access to to Social Security benefits, you may be able to receive disabled widow's or widower's benefits or disabled adult child benefits. These are different programs with different rules, but the process is similar: you file a claim and Social Security evaluates your medical condition.

Frequently Asked Questions

Can I file for disability if I have never worked?

No. SSDI requires work credits, which you earn only through paid employment. If you have never worked, you may be able to receive Supplemental Security Income (SSI) instead, which is a needs-based program with no work requirement. SSI has strict income and asset limits. Contact Social Security to learn whether you might be may be able to access for SSI.

Do I need a lawyer to file for disability?

No. You can file and represent yourself throughout the process. However, many people hire a lawyer after a denial because the appeal process is complex and the rules about medical evidence are strict. A lawyer can help you gather evidence and present your case to a judge. You do not need to hire a lawyer upfront; you can file on your own and hire one later if you are denied.

How much back pay will I receive if I am approved?

Back pay is the amount of benefits owed from the date you became disabled to the date your claim is approved. Social Security does not pay back pay for the first five months you are disabled; this is called the waiting period. So if you became disabled in January and are approved in September of the following year, you receive back pay starting in June (five months after January). The amount depends on your average earnings history.

What if my condition gets worse while I am waiting for a decision?

You can submit new medical evidence at any time during the process. If your condition has worsened, send updated records from your doctors showing the change. This evidence will be reviewed along with everything else in your file. If you are denied and then your condition worsens significantly, you can file a new claim based on the new evidence.

Can I work while my disability claim is pending?

Yes. Working does not disqualify you from receiving benefits, but earning substantial income (more than $1,550 per month in 2024) may cause Social Security to deny your claim on the grounds that you are capable of substantial work. If you are working part-time or earning less than the substantial work threshold, you can continue while your claim is pending. Be honest about your work on your process.
