Where to find your back pay amount

Social Security will tell you the exact amount of back pay you're owed in a document called the Award Notice. This is the official letter you receive after your claim is approved. The Award Notice lists three numbers: your monthly benefit amount, the date your benefits officially start, and the total back pay you will receive.

You can view your Award Notice in three ways. If you have a my Social Security account (the free online portal at ssa.gov), you can log in and find it under "Messages" or "Documents." If you don't have an account yet, you can create one with your email, Social Security number, and proof of identity. The second way is to call Social Security directly at 1-800-772-1213 and ask them to read the back pay amount from your file. The third way is to visit your local Social Security office in person and ask for a copy of your Award Notice.

Key Takeaways

  • Your Award Notice is the official document that shows exactly how much back pay Social Security owes you, and you receive it when your claim is approved.
  • You can access your Award Notice through your my Social Security account online, by calling 1-800-772-1213, or by visiting a local Social Security office.
  • The back pay amount is calculated from your official start date (the date your disability is determined to have begun) back to the date you filed your claim, minus any waiting period.
  • If you received Supplemental Security Income (SSI) while waiting for SSDI approval, Social Security will subtract that from your back pay to avoid overpaying you.

Understanding the dates on your Award Notice

The back pay calculation depends on two dates that appear on your Award Notice. The first is your established onset date (EOD) — the date Social Security determines your disability actually began. This is not the date you filed your claim; it's the date you became unable to work due to your condition. Social Security uses medical records and your own statements to set this date.

The second date is your date of award — the date your claim was officially approved. Your back pay covers the months between your established onset date and your date of award, minus the five-month waiting period that all SSDI recipients must serve. For example, if your established onset date is January 2023 and you were approved in September 2024, Social Security counts back from September 2024, subtracts five months, and pays you for the remaining months back to January 2023.

These dates are crucial because they directly determine your dollar amount. If you believe either date is wrong on your Award Notice, you should contact Social Security when ready to request a correction, because the dates cannot be changed after a certain point in the process.

What happens if you received SSI while waiting

If you were receiving Supplemental Security Income (SSI) before your SSDI claim was approved, Social Security will reduce your back pay by the amount of SSI you already received. This is called an SSI offset. The reason is that SSI and SSDI are both need-based programs, and the government does not pay you twice for the same months.

For example, if your total SSDI back pay is $8,000 but you received $3,000 in SSI during those same months, Social Security will pay you $5,000 in SSDI back pay. Your Award Notice will show both the gross back pay amount (before the offset) and the net amount (after the offset) so you can see the calculation.

If you think the SSI offset is calculated incorrectly, you can ask Social Security to review it. Keep records of all SSI payments you received, because you may need to show them as proof if you dispute the amount.

How to read the numbers on your Award Notice

Your Award Notice breaks down the back pay into separate line items so you can see exactly how it was calculated. At the top, it will show your monthly SSDI benefit amount. Below that, it lists the number of months you are owed back pay for. Then it shows the total back pay before any deductions.

Further down, the notice will list any deductions — such as an SSI offset, a workers' compensation offset, or a family maximum reduction. After all deductions are subtracted, the final line shows your net back pay, which is the actual amount Social Security will send you.

The notice also states when you will receive the back pay. Most people receive it as a single lump sum within two weeks of the approval date, though in some cases it may be split into multiple payments. The notice will specify the payment method — direct deposit to your bank account, a check, or a debit card.

Why your back pay might be less than you expected

Back pay is sometimes smaller than people anticipate because of reductions that are built into SSDI rules. The most common reason is the family maximum. If you have a spouse or children also receiving benefits on your record, there is a cap on the total amount the family can receive each month. When this cap is reached, individual family members' benefits are reduced proportionally, and this reduction also applies to back pay.

Another reason is the workers' compensation offset. If you are receiving workers' compensation benefits for the same disability, Social Security may reduce your SSDI back pay dollar-for-dollar by the amount of workers' compensation you received during the same period.

A third reason is that you may have worked and earned income during some of the months you are owed back pay. SSDI has a substantial gainful activity (SGA) limit — if you earned more than that amount in a month, Social Security may not count that month toward your back pay, even if you were disabled.

What to do if your Award Notice doesn't arrive

If you were approved for SSDI but have not received your Award Notice within two weeks of approval, contact Social Security at 1-800-772-1213 or visit your local office. Do not wait — the Award Notice is your proof of the back pay amount, and you will need it for your records and for tax purposes (back pay is taxable income).

If you have a my Social Security account, check there first before calling. Sometimes the notice appears in your online account before a physical copy arrives in the mail. If it is in your account, you can print it or save it as a PDF.

If you lost your Award Notice or need another copy, Social Security will send you one at no cost. straightforward call or visit your local office and request a duplicate.

Frequently Asked Questions

Can I get my back pay faster than two weeks?

No. Social Security processes back pay payments on a standard schedule, and the timing depends on your payment method. Direct deposit is fastest, usually arriving within two weeks of approval. Checks take longer. You cannot request expedited payment, but you can confirm the payment method on your Award Notice to make sure it is set to your preference.

What if Social Security says I owe them money instead of owing me back pay?

This happens when you received benefits you were not may have access to to — for example, if you worked and earned too much during a month but did not report it. Social Security will explain the overpayment on your Award Notice. You can request a waiver of the overpayment or set up a repayment plan, but you must act within 60 days of receiving the notice.

Is my back pay subject to taxes?

Yes. SSDI back pay is considered taxable income in the year you receive it. Social Security will send you a Form SSA-1099 showing the amount. You may owe federal income tax on it, depending on your total income for that year. Some people set aside money from the back pay to cover the tax bill when it comes due.

Can I appeal if I think my back pay amount is wrong?

Yes. You have 60 days from the date on your Award Notice to request an appeal if you believe the back pay calculation is incorrect. You can file the appeal online through your my Social Security account, by phone, or in person at your local office. Bring any documents that support your claim, such as medical records or proof of when your disability began.

What happens to my back pay if I'm also getting benefits for my children?

Your children's back pay is calculated separately from yours, but both are subject to the family maximum. Social Security will show on your Award Notice how much each family member receives and whether the family maximum reduced anyone's amount. If you think the calculation is wrong, you can request a detailed breakdown from Social Security.
