What applying for Supplemental Security Income generally involves: what to gather, what happens after you apply and what to do if you are denied.

Applying for SSI takes some preparation, and it helps to know the general shape before you start. This walkthrough covers what to gather, what the agency usually asks, what happens next and what to do if the answer is no.

Before you start: gather your papers

Having these ready can save time. Not everyone needs every item.

  • Proof of identity and age, such as a birth certificate
  • Proof of citizenship or immigration status
  • Your Social Security number, or the applicant’s
  • Information about where you live and who you live with, such as a lease or rent receipts
  • Records of income: pay stubs, benefit letters, support payments
  • Records of resources: bank statements, vehicle details, insurance policies
  • For disability claims: names of doctors, clinics and hospitals, dates of visits, medications and test results

Starting the application

In general, you can begin online, by phone or at a local office. If the application is for a child or for someone who needs help, a parent, guardian or representative can usually assist. Write down the date you first contacted the agency, as it can matter.

What you will be asked

Expect detailed questions about money, property, your household and, for disability, how your condition affects daily life and work. Answer honestly and completely. If you do not know something, say so and follow up.

After you apply

  • The agency checks your financial eligibility.
  • For disability claims, it gathers medical records and may ask for an exam.
  • You may be contacted for more information. Respond quickly.
  • You will receive a written decision.

This often takes time. Keep copies of everything you send and notes of every call.

If you are denied

A denial is not always the end. You generally have the right to ask for the decision to be reviewed, and there are several levels of appeal. Deadlines apply and are short, so read the letter carefully and act quickly. Many people find it helpful to get support from a legal aid organisation or an experienced advocate.

Once approved

Benefits come with responsibilities. Report changes promptly and keep records. Read what changes to report while on SSI.
