The form you use depends on whether you are explore for the first time or reporting a change
Social Security has different forms for different situations. If you have never received disability benefits, you will start with Form SSA-16, the process for Disability Insurance Benefits. If you are already receiving benefits and need to report that you returned to work, got married, or had another life change, you use Form SSA-777, the Report of Work Activity. If you are explore as a family member of someone who receives disability, you use Form SSA-8, the process for Family Member Benefits.
You can get these forms from your local Social Security office, by calling 1-800-772-1213, or by downloading them from ssa.gov. You do not have to print and mail them — you can also complete them in person at an office, or in some cases over the phone with a representative.
Key Takeaways
- Form SSA-16 is the initial process for disability benefits and asks about your medical condition, work history, and household income.
- Form SSA-777 is used to report changes like returning to work, marriage, or a change in living situation while you are already receiving benefits.
- You can submit forms by mail, in person at a Social Security office, or by phone with a representative.
- Social Security will ask for medical records, so having your doctor's contact information and dates of treatment ready speeds up the process.
- The form itself does not determine whether you receive benefits — a claims examiner reviews your medical evidence and work history after you submit it.
Form SSA-16: The Initial Disability process
Form SSA-16 is the document you complete when you are explore for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) for the first time. The form asks for your name, Social Security number, date of birth, and contact information. It then moves into questions about your medical condition: when it started, what doctors or hospitals have treated you, and what medications you take.
The form also asks about your work history — the jobs you have held in the past 15 years, what you did in each job, and when you stopped working. Social Security uses this to understand whether your condition prevents you from doing the work you did before. You will also report your household income and assets, because SSI has income and resource limits that SSDI does not.
You do not need to have the form completely filled out before you submit it. If you are missing information — such as the exact address of a doctor you saw years ago — you can leave it blank and Social Security will try to locate the records themselves. Submitting an incomplete form is better than waiting until you have every detail.
Form SSA-777: Reporting Work or Life Changes While Receiving Benefits
If you are already receiving disability benefits and your situation changes, you must report it to Social Security. Form SSA-777 is used to tell them about changes such as returning to work, earning more than the monthly limit, getting married or divorced, moving to a different state, or a change in your living arrangement.
The form asks which change you are reporting and the date it happened. If you returned to work, you will report your job title, the name and address of your employer, how many hours you work per week, and how much you earn per month. Social Security tracks this because SSDI has a trial work period and an earnings limit; SSI has a lower earnings limit and different rules about what counts as income.
You should report changes within 30 days of when they happen. If you do not report and Social Security finds out later, your benefits may be reduced or stopped, and you may have to repay money you received while ineligible.
Form SSA-8: explore as a Family Member
If someone in your household receives disability benefits, you may be able to receive benefits as their spouse, ex-spouse, or child. Form SSA-8 is the process for family member benefits. You will need the beneficiary's Social Security number and information about your relationship — your marriage certificate if you are a spouse, or a birth certificate if you are a child.
The form asks about your age, work history, and whether you are caring for the beneficiary's child under age 16. Social Security uses this information to determine whether you meet the rules for your category. A spouse must be at least 62 years old (or any age if caring for a child under 16); a child must be under 19 (or 19 if still in high school full-time); an ex-spouse must have been married for at least 10 years.
What Information You Should Gather Before You Start
Before you sit down with a form, collect the documents and information Social Security will ask about. Have your Social Security number, birth certificate, and proof of citizenship or legal residency ready. If you are explore for disability, gather the names, addresses, and phone numbers of all doctors, hospitals, and clinics that have treated you for your condition. Include the dates you saw each provider.
If you have medical records at home — test results, letters from doctors, hospital discharge papers — bring those too. Social Security will request records from your providers, but having copies on hand can speed things up. If you worked in the past 15 years, write down the names of your employers, the dates you worked, your job titles, and what you did in each job. If you are reporting a work change on Form SSA-777, have your pay stubs or a letter from your employer showing your current earnings.
Where to Submit Your Form
You have three main ways to submit a form. You can mail it to your local Social Security office — the address is on the form itself. You can walk into a Social Security office in person and submit it there; an employee can answer questions as you fill it out. You can also call 1-800-772-1213 and complete the form over the phone with a representative, who will file it for you.
If you mail the form, keep a copy for your records and consider sending it by certified mail so you have proof of the date you submitted it. Social Security's processing time varies depending on the form and your situation, but you should expect to hear back within 30 to 60 days for a change report, or several months for an initial process.
What Happens After You Submit
Once you submit your form, a claims examiner at Social Security will review it. For an initial process, they will request your medical records from the doctors and hospitals you listed. They may also send you to a doctor for an examination paid for by Social Security. The examiner will look at whether your condition meets Social Security's definition of disability — it must prevent you from doing substantial work for at least 12 months or result in death.
For a change report, Social Security will verify the information you provided. If you reported returning to work, they may contact your employer to confirm your earnings. If you reported a change in living situation, they may verify your new address. You will receive a notice in the mail telling you whether your benefits continue, change, or stop.
Frequently Asked Questions
