Please answer a few questions to help us determine your eligibility.
1. What SSDI Back Pay Covers
- Back pay is typically owed for the months between your disability onset date (when you first became disabled) and the approval date of your SSDI application.
- You may also be entitled to retroactive payments for up to 12 months before your application, depending on the onset date and your work history.
2. How SSDI Back Pay is Calculated
- SSDI benefits are calculated based on your average lifetime earnings and your work history.
- Back pay is based on the benefits you would have received had your application been approved earlier.
- The SSA will determine how many months of back pay you are owed, factoring in the waiting period and approval delays.
3. How Long It Takes to Receive Back Pay
- Processing time for SSDI claims can be lengthy, often taking several months or even years.
- Once approved, the SSA will send the back pay in a lump sum or in installments.
- Typically, the SSA will issue back pay after approval but it can take anywhere from 60 to 90 days.
4. Maximum Waiting Periods and Delays
- SSDI applicants generally have to wait a five-month waiting period from their disability onset date before receiving any benefits.
- However, back pay can cover the months before the waiting period, depending on the exact onset date.
5. Receiving SSDI Back Pay in Oregon
- Back pay is usually sent directly to the beneficiary’s bank account or by check.
- If you’re approved for both SSDI and Supplemental Security Income (SSI), you may receive separate payments for both programs.
- It’s important to keep track of your benefits as back pay can affect other state benefits or programs you might be receiving.
6. What to Do if You Don’t Receive Your Back Pay
- If there’s a delay or error in the back pay process, contact the Social Security Administration immediately.
- You may also appeal decisions regarding back pay if you believe the amount or approval date is incorrect.

By understanding how SSDI back pay works in Oregon, individuals can better manage their expectations and plan their finances accordingly while waiting for their benefits.
