What form you need depends on how you're applying
Social Security has different forms for different situations, and using the wrong one delays your case. If you're applying for disability for the first time, you'll use Form SSA-16 (Application for Disability Insurance Benefits). If you're already receiving Social Security retirement or survivor benefits and now need to switch to disability, you'll use Form SSA-8 instead. If someone else is applying on your behalf — because you're unable to manage your own affairs — they'll file Form SSA-3368 (Supplemental Security Income Application for Adults).
You can get the correct form from Social Security's website, by calling 1-800-772-1213, or by visiting your local Social Security office in person. The office staff can tell you which form matches your situation and sometimes help you start filling it out while you're there.
Key Takeaways
- Form SSA-16 is for first-time disability applicants; Form SSA-8 is if you're already receiving other Social Security benefits.
- You'll need to provide your medical records, work history, and details about how your condition limits what you can do.
- Social Security will also ask for names and dates of doctors, hospitals, and therapists who have treated you.
- You can submit the form by mail, in person at a Social Security office, or sometimes online through your Social Security account.
- After you submit, Social Security sends your case to a state disability agency that reviews medical evidence and makes the decision.
What information you'll need to gather before you start
Have these documents and details ready before you sit down with the form. You'll need your Social Security number, birth certificate, and proof of citizenship or legal residency. Bring your driver's license or other photo ID.
Gather a list of every doctor, hospital, mental health provider, and therapist who has treated you for your condition. Include their names, addresses, phone numbers, and the dates you saw them. If you've had surgery, imaging, lab work, or other tests, write down where those happened and when. Social Security will contact these providers directly to get your medical records, so accuracy matters — a wrong phone number can delay your case by weeks.
Write down your work history for the past 15 years: the jobs you held, the dates you worked, and what you did. Include self-employment if you had it. Also list any schooling or training you completed after high school.
How to fill out the medical and work sections
The form asks you to describe your condition and how it affects your daily life and work. Be specific about what you cannot do, not just the diagnosis. For example, don't write "back pain" — write "cannot sit for more than 30 minutes without severe pain" or "cannot lift more than 10 pounds." Social Security reviewers need to understand the real limits your condition creates.
List every medication you take, including the dose and how often. If you've tried treatments that didn't work or had side effects, mention those too. The form also asks about your mental state — whether you have trouble concentrating, remembering things, or managing daily tasks. Answer honestly, even if it feels uncomfortable.
In the work section, explain when your condition started affecting your ability to work and what changed. If you tried to keep working but had to stop, describe what happened. If you're still working but struggling, say that too — Social Security needs to know your current situation.
Where to submit your form and what happens next
You can mail the completed form to your local Social Security office (the address is on the form itself), drop it off in person, or upload it through your Social Security account online if you have one set up. If you mail it, keep a copy for your records and consider using certified mail so you have proof of delivery.
After Social Security receives your form, they send it to your state's disability information agency. That agency reviews your medical records, may order new tests or exams, and makes the decision to approve or deny your case. This process typically takes three to six months, though it can take longer if your case is complex or if the agency needs more information from your doctors.
Social Security will contact you by mail if they need anything else. If you don't hear from them within a few weeks, call 1-800-772-1213 to confirm they received your form.
Common mistakes that slow down your case
Leaving sections blank or writing "see attached" instead of filling in the form itself creates delays. Social Security needs the information on the form itself, not in a separate letter. If a question doesn't apply to you, write "N/A" rather than leaving it blank.
Providing incomplete contact information for your doctors is one of the biggest causes of delays. A wrong phone number or address means Social Security can't reach them to get your records. Call your providers before you submit the form and confirm their current contact details.
Underestimating how your condition affects you is another common problem. Some people minimize their symptoms because they don't want to seem like they're complaining, or because they're used to pushing through pain. Social Security needs the full picture of what you can and cannot do. If your condition is severe enough that you can't work, say that clearly.
What to do if you're denied and want to appeal
If Social Security denies your case, you have the right to appeal. You'll receive a notice explaining why they denied you, and that notice will tell you how to request reconsideration. You typically have 60 days from the date on the notice to file an appeal.
For your first appeal, you can request reconsideration, which means a different Social Security examiner reviews your case. You can submit new medical evidence at this stage — if you've had additional treatment or testing since your first application, include those records. Many people are approved on reconsideration because they have more recent medical evidence.
If reconsideration is also denied, you can request a hearing before an administrative law judge. At a hearing, you can present your case in person and answer questions about how your condition affects you. Many people find it helpful to have a lawyer or representative at a hearing, though it's not required.
How to get help filling out the form
Social Security staff at your local office can answer questions about the form and sometimes help you complete it. Call ahead to ask if they offer this service, as some offices are busier than others.
If you have a lawyer or representative who handles disability cases, they can help you fill out the form and make sure you're providing the information Social Security needs. Many disability lawyers work on contingency, meaning they only get paid if your case is approved, and they take their fee from your back pay.
Some nonprofit organizations in your area offer free help with disability applications. You can find these through your state's disability information agency or by searching online for "disability application help" plus your county name.
Frequently Asked Questions
Can I submit the form online instead of mailing it?
You can create a my Social Security account and upload documents there, but you typically still need to complete the initial application by phone or in person at an office. Call 1-800-772-1213 to start your application, then ask whether you can submit the form online for your specific situation.
What if I don't have medical records from all my doctors?
List the doctors and providers you do remember, with as much contact information as you can find. Social Security will contact them and ask them to send your records. If you're missing records from a provider who's no longer in practice, write that on the form and explain what you remember about your treatment there.
Do I need a lawyer to apply for disability?
No, you can apply on your own. A lawyer is helpful if your case is denied and you're appealing, because the appeal process is more formal. For your initial application, having complete and accurate medical records matters more than having legal representation.
How long does it take to hear back after I submit the form?
Social Security typically contacts you within two to four weeks to confirm they received your application and to ask any follow-up questions. The full decision from the state disability agency usually takes three to six months, depending on how complex your case is and how quickly your doctors respond with records.
Can I work while my disability case is being decided?
Yes. You can work and earn money while your case is pending. However, if you're earning substantial income, it may affect your case, because Social Security looks at whether you can do any work. Be honest about any work you're doing when you fill out the form.
