Your Date Last Insured is when Social Security stops counting your work credits toward disability

Date Last Insured (DLI) is the final month Social Security will recognize your work credits if you become disabled. It is not the date you stop working — it is a important date Social Security uses to decide whether you have enough recent work history to receive SSDI. If you become disabled after your DLI passes, Social Security will deny your claim, even if you have accumulated 40 work credits total.

Social Security calculates your DLI based on when you last earned work credits. The agency assumes you stop earning credits when you stop working or when your income falls below the annual earnings threshold. Once 12 months pass without a new work credit, your DLI is set. After that date, you have a limited window — usually five years — to file a claim. If you file after that window closes, you lose the right to SSDI based on that work history.

Understanding your DLI matters because it determines whether you can receive SSDI at all. You cannot extend it by working again unless you earn enough credits to establish a new DLI. The date appears on your Social Security Statement and in any correspondence from Social Security about your account.

Key Takeaways

  • Your Date Last Insured is set 12 months after your last work credit and marks the important date for filing an SSDI claim based on that work history.
  • If you become disabled after your DLI passes and you do not file within five years of that date, you lose the right to SSDI under that work record.
  • You can establish a new DLI by returning to work and earning at least one work credit in a calendar year, which resets the 12-month countdown.
  • Social Security sends your DLI on your annual Statement, and you can also request it by calling 1-800-772-1213 or visiting your local office.

How Social Security calculates your Date Last Insured

Social Security assigns you a work credit each calendar quarter when you earn a minimum amount of income. In 2024, you need $1,730 in earnings per quarter to receive one credit; that threshold changes yearly. Once you stop earning credits, Social Security waits 12 months, then sets your DLI as the last month you earned a credit.

For example: if your last work credit was in the third quarter of 2022 (July–September), your DLI would be September 2023 — 12 months later. If you file an SSDI claim in October 2023, you are still within the window. If you file in October 2028 — more than five years after your DLI — Social Security will deny the claim because you filed too late, even if you have enough total credits.

The 12-month waiting period exists because Social Security assumes you may return to work temporarily. If you earn even one credit in that 12-month window, the countdown resets. Your DLI moves forward to 12 months after that new credit. This means working part-time or taking a short job can extend your DLI significantly.

The five-year filing window after your Date Last Insured

Once your DLI is set, you have five years from that date to file an SSDI claim. This is called the five-year window. If you file within the window, Social Security will review your claim using your work history up to your DLI. If you file after the window closes, Social Security will deny your claim outright — they will not even examine whether you are disabled.

The five-year window is separate from the 12-month waiting period. Here is the timeline: you stop working in September 2022 (last credit). Twelve months later, in September 2023, your DLI is set. You then have until September 2028 to file a claim. If you file in October 2028, you are outside the window and ineligible.

This rule applies even if you become severely disabled the day after your five-year window closes. Social Security will not make exceptions based on the severity of your condition or how close you came to the important date. The only way to reopen may be able to access is to return to work, earn new credits, and establish a new DLI.

What happens if you work again after your Date Last Insured

If you return to work after your DLI is set, you can establish a new DLI by earning at least one work credit in a calendar year. This resets the entire timeline. Your new DLI will be 12 months after that new credit, and you will have a fresh five-year window to file a claim.

This can be helpful if you become disabled years after your original DLI passes. Suppose your first DLI was September 2023, and you did not file by September 2028. If you then work part-time in 2029 and earn one credit, your new DLI becomes 12 months after that credit. You now have a new five-year window to file. However, Social Security will only count work credits earned after your previous DLI when determining your benefit amount — your earlier credits are no longer part of your insured status calculation.

Returning to work is not a straightforward solution if you are already disabled or unable to work. It requires earning enough income to meet the quarterly threshold, which may be impossible if your condition prevents employment. Speak with a Social Security representative about your specific situation before assuming you can extend your DLI through work.

Finding your Date Last Insured

Your DLI appears on your Social Security Statement, which you can view online at ssa.gov by creating a my Social Security account. The Statement lists your work history, total credits earned, and your current DLI. You can also request a printed Statement by mail, though online access is faster.

If you do not have a my Social Security account, you can create one at ssa.gov/myaccount. You will need your Social Security number, date of birth, and a valid email address. Once logged in, select "View your Statement" to see your DLI and earnings record. If you see an error — for example, a missing year of work — you can request a correction through the same account.

You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) to ask about your DLI. Have your Social Security number ready. A representative will tell you your DLI and explain what it means for your situation. Local Social Security offices can also provide this information in person, though wait times vary by location.

Correcting errors in your work history before your Date Last Insured passes

If you believe Social Security missed a year of work or recorded your earnings incorrectly, you should request a correction before your DLI passes. Errors in your work history can lower your DLI or reduce your benefit amount if you are later approved for SSDI.

To correct your earnings record, contact Social Security with documentation of your work — W-2 forms, pay stubs, or tax returns. You have a limited time to request corrections: generally three years, three months, and 15 days after the year in which you earned the income. After that period, Social Security will not adjust your record unless you have evidence of a specific agency error.

If your DLI is approaching or has already passed, correcting your record becomes urgent. A correction that adds a work credit could extend your DLI by 12 months, giving you more time to file a claim. Request corrections in writing through your my Social Security account or by visiting a local office with your documentation.

What your Date Last Insured means if you are already receiving benefits

If you are already receiving SSDI, your DLI does not affect your ongoing benefits. Social Security approved your claim before your DLI passed, so the important date no longer applies to you. Your DLI remains on your record, but it has no practical impact on your monthly payment or your status as a beneficiary.

However, your DLI may matter if you return to work and your benefits are suspended due to substantial gainful activity (SGA). If you later become unable to work again, Social Security may use your original DLI to determine whether you remain insured. In most cases, once you are approved for SSDI, you stay insured as long as you continue to meet the non-medical requirements of the program.

Frequently Asked Questions

Can I file an SSDI claim after my Date Last Insured has passed?

No. If you file more than five years after your DLI, Social Security will deny your claim without reviewing whether you are disabled. Your only option is to return to work, earn at least one work credit in a calendar year, and establish a new DLI. This resets your five-year filing window.

Does my Date Last Insured change if I work part-time?

Yes. If you earn at least $1,730 in a calendar quarter (the 2024 threshold), you receive a work credit and your DLI moves forward 12 months from that credit. Even a few months of part-time work can extend your DLI significantly, but you must earn enough to meet the quarterly threshold.

What if I disagree with the Date Last Insured on my Social Security Statement?

Request a correction through your my Social Security account or by contacting Social Security directly at 1-800-772-1213. Bring W-2 forms, pay stubs, or tax returns showing the work you believe was missed. Social Security can usually correct errors within three years, three months, and 15 days of the year the income was earned.

If I am disabled now but my Date Last Insured passed years ago, can I still get SSDI?

Only if you have returned to work since your DLI passed and earned at least one new work credit. That work credit establishes a new DLI and a new five-year filing window. Without new work credits, you are not insured and cannot receive SSDI, regardless of your disability.
