What form you use depends on which stage of the process rejected you
Social Security uses different forms depending on where your case stopped. If the Social Security Administration (SSA) denied you at the initial stage, you file a Request for Reconsideration (Form SSA-561-U2). If you were already denied once and want to move forward, you file a Request for Hearing by Administrative Law Judge (Form HA-501). If you've had a hearing and lost, you can request Appeals Council Review (Form HA-520). Each form goes to a different office and triggers a different review process.
You do not have to use the official form to appeal—you can write a letter instead—but using the correct form speeds things up because SSA staff know exactly where to send it and what information they're looking at. The form also ensures you include the details SSA needs to find your file and understand what stage you're at.
Key Takeaways
- Form SSA-561-U2 (Request for Reconsideration) is what you file after an initial denial, and it asks SSA to review your case a second time with new or existing evidence.
- Form HA-501 (Request for Hearing) moves your case to an administrative law judge if reconsideration was denied, and this is usually where cases are decided in the applicant's favor.
- Form HA-520 (Appeals Council Review) is filed only after a hearing decision goes against you, and it asks a higher-level panel to review the judge's reasoning.
- You can submit a letter instead of a form, but the form includes checkboxes and fields that help SSA process your request faster and route it to the right office.
- The important date to file any appeal is 60 days from the date on the decision letter you received, though SSA may accept late filings if you have a good reason.
Form SSA-561-U2: Request for Reconsideration
This is the first form you file after SSA denies you at the initial stage. You send it to the same Social Security office that made the first decision. On the form, you check a box to say whether you want a new review based on new evidence, or whether you want SSA to look at the same evidence again with fresh eyes. Most people check "new evidence" and include medical records, test results, or statements from doctors that weren't in the first file.
The form asks for your name, Social Security number, the date of the decision letter you're appealing, and a brief statement of why you think the decision was wrong. You do not need to write a long explanation—SSA will read your whole file. The form itself is short, usually one page. You can get it from SSA.gov or ask for a copy at your local Social Security office.
Mail the completed form to the address listed on your decision letter, or bring it in person to your local office. Keep a copy for your records. SSA will send you a notice when they receive it and tell you roughly how long the review will take—usually 3 to 6 months.
Form HA-501: Request for Hearing by Administrative Law Judge
You file this form if SSA denied your reconsideration request, or if you skip reconsideration and go straight to a hearing (which you can do). This form tells SSA you want a hearing in front of an administrative law judge (ALJ), who is independent from the SSA office that made the first decision. The judge will review your entire file, read any new evidence you submit, and may hold a hearing where you or a representative can speak.
On Form HA-501, you list your name, Social Security number, and the date of the decision you're appealing. You can check a box to say whether you want a hearing in person, by video, or by phone. You can also write a statement explaining why you believe you are disabled. This statement matters—judges read it, and it gives you a chance to describe your condition in your own words rather than relying only on medical records.
You can also use this form to name a representative—a lawyer, advocate, or other person who will speak for you at the hearing. If you name someone, SSA will send them copies of documents and notices instead of sending them only to you. Mail the form to the address on your reconsideration decision letter, or submit it online through your "my Social Security" account if you have one set up.
Form HA-520: Appeals Council Review
This form is filed only after you have had a hearing in front of an administrative law judge and lost. It asks the Appeals Council—a panel that sits above the judge—to review whether the judge made an error in law or fact. You do not get another hearing; the Appeals Council reads the judge's decision, your file, and any new evidence you submit, then decides whether to overturn the judge or let the decision stand.
On Form HA-520, you explain what you believe the judge got wrong. You might say the judge ignored medical evidence, misunderstood your symptoms, or applied the wrong legal standard. Be specific: point to the page number in the hearing transcript or the date of a medical record. The Appeals Council is more likely to reverse a decision if you show them exactly what the judge overlooked.
You have 60 days from the date on the judge's decision letter to file this form. Mail it to the address listed on that letter. The Appeals Council usually takes 6 months to a year to issue a decision, though some cases move faster.
Where to send each form and what happens next
Each form has a specific destination and triggers a specific process. The address where you send the form is always listed on the decision letter you received—do not guess or use an old address. Sending the form to the wrong office delays your case because it has to be forwarded, and you may not receive timely notice of what is happening.
After you mail the form, SSA or the hearing office will send you a receipt notice confirming they received it. Keep this notice. If you do not hear back within two weeks, call the office listed on your decision letter to confirm they have your form. If you submitted new medical evidence, ask them to confirm they received it as well.
| Form | When you file it | Where it goes | What happens next |
|---|---|---|---|
| SSA-561-U2 (Reconsideration) | After initial denial | The Social Security office that made the first decision | SSA reviews your file with new or existing evidence; sends you a decision letter in 3–6 months |
| HA-501 (Hearing Request) | After reconsideration denial, or instead of reconsideration | The hearing office listed on your reconsideration decision letter | An administrative law judge schedules a hearing; you present evidence and testimony; judge issues a written decision in 1–3 months after the hearing |
| HA-520 (Appeals Council Review) | After an unfavorable hearing decision | The Appeals Council office listed on the judge's decision letter | The Appeals Council reviews the judge's decision; sends you a written decision in 6–12 months |
How to fill out the form correctly so SSA doesn't delay your case
Use black or blue ink if you are writing by hand, or type the form on a computer. Print it clearly—SSA staff scan these forms, and if the scanner cannot read your handwriting, someone has to re-enter the information by hand, which slows everything down. Fill in every field that applies to you. If a field does not explore, write "N/A" instead of leaving it blank, so SSA knows you saw the question.
Always include your full name and Social Security number at the top of the form and on every page if the form is more than one page. Write the date you are signing the form. If you are using a representative, have them sign as well and write their phone number and address. If you are submitting new medical evidence, attach it to the form with a cover letter that lists what you are sending—for example, "Enclosed: cardiology report dated March 15, 2024; lab results dated April 2, 2024."
Do not assume SSA has your current address. Write your mailing address clearly on the form. If your address has changed since your last contact with SSA, call 1-800-772-1213 to update it before you mail the form, so SSA's decision letter reaches you.
What to do if you miss the 60-day important date
The important date to file an appeal is 60 days from the date on the decision letter you received. If you miss this important date, you can still file, but you must include a written explanation of why you missed it. SSA calls this a "good cause" statement. Common reasons SSA accepts are: you did not receive the decision letter, you were hospitalized or seriously ill, you did not understand you had to appeal, or your representative failed to file on time.
Write a short letter explaining what happened and attach it to your appeal form. Be honest and specific—"I was in the hospital from June 10 to July 5" is stronger than "I was sick." SSA will decide whether to accept your late filing. Even if they do not, you can still ask a judge to review the decision, so a late filing does not end your case.
Frequently Asked Questions
Can I write a letter instead of using the official form?
Yes. A letter works, but the form is faster because SSA staff know exactly what information to look for and where to send it. If you write a letter, include your name, Social Security number, the date of the decision you are appealing, and a statement of why you disagree with the decision. Mail it to the same address where the form would go.
Do I have to use a representative to appeal?
No, but many people do. A representative—a lawyer, advocate, or other person—can help you gather evidence, write your statement, and speak at a hearing. You name them on the form by checking the box and writing their name and contact information. They do not have to be a lawyer; they can be a family member or a disability advocate.
What if I want to submit new medical evidence with my appeal?
Attach it to the form with a cover letter listing what you are sending and the dates of the records. New evidence is especially important at the reconsideration stage—it gives SSA a reason to change the first decision. At the hearing stage, the judge will consider both old and new evidence together.
How long does each stage take?
Reconsideration usually takes 3 to 6 months. A hearing typically takes 3 to 6 months to schedule, then 1 to 3 months after the hearing for the judge to issue a decision. Appeals Council review takes 6 months to a year. Timelines vary by office and caseload.
What happens if I file the form but then decide to hire a representative?
You can name a representative at any point in the appeal. Fill out a new form or send a letter to the office handling your case, stating the representative's name and contact information. SSA will then send all future notices to the representative instead of to you.
