When Will I Receive My Social Security Disability Back Pay?

For most disability claimants (applicants), approval for Social Security disability can take months or even years. By the time many applicants are approved, they’re already in serious debt. That’s why one of the first questions SSDI and SSI recipients often ask after approval is when they’ll receive past-due payments, or “back pay.” Back pay is the money you’re owed for the time you waited—from when you became eligible until the Social Security Administration (SSA) approved your claim.

Both SSDI and SSI disability back pay cover the period from your application to approval—often six months to two years. SSDI back pay can also include retroactive benefits for the time you were disabled before applying.

In most cases, Social Security sends back pay within a few weeks to a few months—usually about 30 to 60 days—but delays can occur in more complex cases. SSDI back pay is paid in a lump sum, while SSI back pay might be split into installments if the amount is large.

Below, we explain how long it takes to get SSDI and SSI disability back pay, what can affect the timeline, and what to do if it’s delayed.

How Long Does It Take to Get SSDI Back Pay?

Usually, a claimant will receive their SSDI back pay within 60 days of being approved. But it doesn't always work out that way.

Sometimes the back pay comes very quickly. In fact, your back pay might be deposited into your bank account before Social Security sends out the award notice. Other times, a claimant's back pay can seemingly fall into an abyss, and months will pass before it's received. Complex cases or very large payments (more than $30,000) usually take the longest.

Much of this inconsistency is because SSDI back pay isn't processed at the Social Security office where you apply (the field office) or the office where you’re approved for benefits (Disability Determination Services). Instead, Social Security’s payment centers, often in other states, handle SSDI back pay while managing large volumes of work.

When Will I Receive My SSI Back Pay?

SSI back pay is often sent within 30 to 60 days. Past-due benefits for SSI are processed at the local Social Security office, but payments can be delayed while Social Security requests your updated income and asset information to confirm you’re still eligible—the SSA checks financial eligibility both at the start of the disability process and again before sending your first payment.

In a survey of SSI recipients, we found the average time from the approval decision to the first payment was just over two months, with most receiving their checks within seven weeks.

Larger amounts of SSI back pay are often paid in up to three installments, spaced about six months apart. The installments might not be equal, as the first two can’t be more than three times your maximum monthly benefit amount.

So if you're owed more back benefits than three months' worth, expect to wait a while to get your money—unless you can show you need the money now for essentials. To learn more, read our article about SSI installment payments.

What Can Delay Disability Back Pay?

Delays can happen due to claim complexity, large payment amounts, missing information, or processing backlogs at Social Security. Here are several factors that can push your back pay past the typical 30–60 day window:

• Processing backlogs: Payment centers handle large volumes of claims and may be backlogged, especially during periods of high volume.
• Missing or conflicting information: Discrepancies in your earnings record, onset date, or work history must be resolved before payment can be released.
• SSA requests for updated documents: The agency may ask for additional records, proof of living situation (for SSI), or verification of other benefits you receive.
• Attorney fee calculations: If you used a disability attorney, SSA must calculate and withhold their fee (typically 25% of back pay, up to $9,200) before releasing the rest, which can add several weeks.
• Bank account or direct deposit issues: A closed account, name mismatch, or outdated routing number will cause the payment to be returned and reprocessed.
• Government debt offsets: The SSA will identify and deduct unpaid federal taxes, student loans, child support, and workers' compensation offsets.

Who Can You Contact About Your Missing Back Pay?

To find out the status of your payments, you can call Social Security at 800-772-1213 between 8:00 a.m. and 7:00 p.m. or visit your local field office. The claim specialist can tell you if your claim has reached the payment center.

You can also check Social Security's web portal if you've created an online mySocialSecurity account with the SSA. Once you log in, you'll be able to see information about the status of your claim and your payments, including back pay. If you applied for SSDI, you likely already have an online account.

If you've received an award letter and have been waiting months for your back payment, you might want to contact your congressperson for help expediting your payments.

FAQ: Your Questions About Disability Back Pay

How much will my SSDI back pay be?

How much you'll receive in SSDI backpay depends on when you applied for disability, when you became disabled, and when you're approved for benefits.
