Social Security Disability Back Pay: Which Months Count for SSI and SSDI?

November 10, 2026 · 8 min

Show notes

If Social Security approves your disability claim, which months will it pay you for? In this companion episode to the remastered January 9, 2017 Q&A Social Security Disability Today video,

“Understanding Back Pay,” I walk through three dates that can be easy to mix up: when you filed, when Social Security determines your disability began, and when your claim was approved. I explain how Supplemental Security Income (SSI) and Social Security Disability Insurance (SSDI) use those dates differently, where the SSDI waiting period comes in, and why your representative may hesitate to estimate your back pay before a decision.

A clarification for viewers of the remastered video
For an initial SSI claim, the earliest payable month is generally the month after you file or the month after you first meet all eligibility requirements, whichever is later. Keep that rule in mind when following the two SSI examples in the original recording.

Watch Understanding Back Pay (Remastered) on the Q&A Social Security Disability Today YouTube channel to follow the examples step by step.
