Onset Date of Social Security Disability

When you apply for Social Security Disability benefits, you will have to state the date you became disabled. This is called the alleged onset date, or AOD.

If you are applying for Social Security Disability Insurance (SSDI), you determine the date of your AOD. However, the Social Security Administration will not allow you to receive benefits for any time when you were engaged in substantial gainful activity and earning too much money to qualify.

If you are applying for Supplemental Security Income (SSI), your onset date does not matter. That is because SSI benefits are never awarded for earlier than the first day of the month after you file for disability.

If you are applying for Social Security Disability benefits and have a question about your onset date, please contact The Sawaya Law Firm and we will be happy to help you with this issue.
