What is my Date Last Insured?

Eligibility for the Social Security Disability Insurance program is based on your work history. When you work and pay taxes you are building “work credits”. Depending on your age, you must have a certain amount of work credits to be considered “insured”. Much like private medical insurance, once you stop paying a premium (taxes in this case) your insured status will eventually end. For SSDI purposes, the last date in which you are insured under the SSDI program is referred to as your Date Last Insured (DLI). In order to receive benefits from SSDI program, you must meet the disability requirements prior to your DLI. Your DLI will be one of four dates, March 31st, June 30th, September 30th or December 31st. These dates fall on the last day of each quarter.
