The First Step: Decide Which Program Fits Your Situation

Social Security runs two separate disability programs, and which one you contact depends on your work history. Social Security Disability Insurance (SSDI) is for people who have worked and paid Social Security taxes. Supplemental Security Income (SSI) is for people with little or no work history, or very low income and resources. You cannot hold both at the same time, but you can switch from one to the other if your circumstances change.

If you have worked at least five of the last ten years, SSDI is your path. If you have never worked, or worked only briefly, SSI is what you need. If you are unsure about your work history, Social Security can tell you during your first contact — they have your earnings record on file.

The process process is nearly identical for both programs, but the financial rules are different. SSDI has no income or resource limits; SSI does. This matters because it affects what you can own and earn while waiting for a decision.

Key Takeaways

  • You can start a claim by phone, online, or in person at your local Social Security office, and the method you choose does not change how long the decision takes.
  • You will need your Social Security number, birth certificate, and medical records showing your condition and how it limits your work — gather these before you call.
  • The initial decision usually arrives within three to five months, but if Social Security denies you, you have the right to appeal and most people who appeal with a lawyer win.
  • While you wait, you can work part-time and still receive benefits under SSDI's work incentive rules, but SSI has stricter limits on how much you can earn.

Where to File Your Claim

You have three ways to start: by phone, online, or in person. All three routes lead to the same process and the same timeline. The fastest is usually online if you are comfortable with a computer, because you can do it at your own pace and do not have to wait for an appointment.

To file online, go to ssa.gov and look for "explore for Disability." You will create a my Social Security account if you do not have one. The form takes 15 to 20 minutes to complete. You can save your progress and come back later if you need to gather documents.

To file by phone, call Social Security's main number at 1-800-772-1213. Wait times are longest on Tuesdays through Thursdays. An agent will ask you the same questions as the online form and submit your process on the spot. You will receive a confirmation number.

To file in person, find your local Social Security office at ssa.gov/locator. You can walk in during business hours, but calling ahead to schedule an appointment usually means a shorter wait. Bring your Social Security card and photo ID.

Documents You Need Before You File

Social Security will ask for basic information during the process — your name, date of birth, address, and work history. But the real work comes after you file, when they ask for medical evidence. Gathering this before you explore speeds up the process.

You will need the names and addresses of all doctors, therapists, hospitals, and clinics that have treated your condition in the past 12 months. Include dates of visits if you have them. Social Security will contact these providers directly and request your medical records, so you do not have to collect them yourself — but having the list ready saves time.

You will also need your birth certificate, Social Security card, and proof of citizenship or legal residency (a passport, naturalization papers, or a green card). If you are filing for SSI, you will need proof of your income and resources — bank statements, rent receipts, proof of any money you receive.

If you have already been denied by another program (workers' compensation, unemployment, a private disability insurer), bring those denial letters. They do not determine Social Security's decision, but they can help establish the timeline of your condition.

What Happens After You File

Within a few days of filing, you will receive a notice with your claim number and the name of your assigned case worker. Keep this number — you will use it every time you contact Social Security about your claim.

Social Security then sends a form called the Function Report to your home. This is a detailed questionnaire about how your condition affects your daily life — what you can and cannot do, how far you can walk, whether you can lift things, whether you can concentrate. Answer it carefully and honestly. This form carries real weight in the decision.

At the same time, Social Security contacts your doctors and requests your medical records. This usually takes four to six weeks. If a provider is slow to respond, Social Security will send a follow-up request.

Once Social Security has your medical records and your Function Report, they send everything to a Disability information Services (DDS) office in your state. This is a state agency that works under contract with Social Security. The DDS office reviews all the evidence and makes the initial decision.

Timeline From Filing to Initial Decision

The initial decision usually arrives within three to five months of filing. Some cases move faster if the medical evidence is clear and straightforward. Others take longer if Social Security needs to order additional tests or clarification from your doctors.

You will receive your decision by mail. If Social Security approves you, the letter will say when your benefits begin and how much you will receive each month. If they deny you, the letter will explain their reason and tell you how to appeal.

Do not expect a phone call. Social Security communicates by mail for the initial decision. You can check the status of your claim anytime by logging into your my Social Security account or by calling your case worker.

What to Do if Social Security Denies Your Claim

Most first applications are denied. This does not mean you are ineligible — it means Social Security decided the medical evidence did not yet prove you cannot work. The denial is not final. You have the right to appeal.

You have 60 days from the date on the denial letter to file an appeal. The first appeal is called Reconsideration, and it goes back to the DDS office. A different examiner reviews your case and any new medical evidence you have gathered. Reconsideration takes another two to three months.

If Reconsideration is denied, you can request a hearing before an Administrative Law Judge (ALJ). This is where most people win. At a hearing, you can present new medical evidence, testify about how your condition affects you, and have a lawyer or representative argue on your behalf. Hearings usually happen four to six months after you request one.

Hiring a lawyer for the hearing is common and often worth it. Lawyers who handle Social Security cases work on contingency — they take a percentage of your back pay if you win, and nothing if you lose. The percentage is capped by law at 25 percent of back pay or $7,200, whichever is less.

How Your Work History Affects Your Claim

For SSDI, Social Security looks at whether you have worked long enough and recently enough to be insured. You need 40 work credits, and 20 of those credits must be earned in the 10 years before you became disabled. One work credit equals roughly $1,550 in earnings in a year (the exact amount changes yearly). Most full-time workers earn four credits per year.

If you do not have enough credits, you are not insured for SSDI. But you may still be able to file for SSI if your income and resources are low enough. SSI has no work requirement.

If you are approved for SSDI, you can continue to work part-time while receiving benefits. Social Security allows you to earn up to a certain amount each month without losing benefits — this is called the Substantial Gainful Activity (SGA) limit. For 2024, the SGA limit is $1,550 per month. If you earn more than that, Social Security will review whether you are still disabled.

Frequently Asked Questions

Can I file for disability if I am still working?

Yes. Social Security does not require you to stop working before you file. However, if you are earning more than the SGA limit (currently $1,550 per month), Social Security will assume you are able to work and will likely deny your claim. If you are working part-time or earning below the limit, you can file and still receive benefits.

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

Back pay covers the months between when your disability began and when Social Security approves you. Social Security assumes your disability started five months after you filed (this is called the "waiting period"). If you are approved eight months after filing, you would receive three months of back pay. The exact amount depends on your age and work history.

What if I cannot afford to wait for a decision?

Social Security offers an expedited review called Compassionate Allowance for conditions that clearly meet the disability standard — certain cancers, ALS, severe intellectual disability, and others. If your condition qualifies, the decision can come within weeks. Ask your case worker whether your condition is on the Compassionate Allowance list.

Do I need a lawyer to file?

No. You can file and handle your case yourself. However, if Social Security denies you and you appeal to a hearing, having a lawyer or representative increases your chances of winning. Most people do not hire a lawyer until the hearing stage, when the stakes are higher.

What happens to my benefits if I go back to work?

For SSDI, you can earn up to the SGA limit without losing benefits. Above that, Social Security reviews your case. For SSI, the rules are stricter — you lose $1 in benefits for every $2 you earn above $65 per month. Both programs have work incentive programs that let you test your ability to work without when ready losing all benefits.
