Why did I get this rejection?

The IRS checks that the date of birth for the primary taxpayer on your return matches what’s on file with the Social Security Administration.

This rejection means the date of birth entered on your return doesn’t match IRS records. In most cases, this happens because the information the IRS receives from the Social Security Administration is incorrect or outdated.


How to fix the rejection

There are a few steps you can take to get this resolved. Start with the checks below, then resubmit your return in april once everything’s updated.


Double-check the date of birth on your return

Start by confirming the date of birth you entered.

  • Compare the date on your return to an official document

  • Use a Social Security card, birth certificate, passport, or government-issued ID

  • Make sure the month, day, and year are entered correctly

Even a small typo can cause a rejection.


Correct the information and resubmit

If you find an error:

  • Update the date of birth in april

  • Save your changes

  • Resubmit your return electronically

If the mismatch was due to a data entry error, e-file should work once it’s corrected.


If the date of birth is correct but the rejection continues

If the date of birth on your return matches your official documents, the issue is likely with Social Security Administration records.


In this case:

  • Contact the Social Security Administration (SSA) to verify your records

  • Call 800-772-1213 or visit ssa.gov to find a local office

  • Ask when the update will be shared with the IRS

Updates can take four to six weeks to process and reach the IRS system.


If you need to file before the issue is fixed

If correcting Social Security records will take time and you’re close to the filing deadline:

Paper filing allows your return to be processed even if e-file isn’t available.


Preventing this issue in the future

To avoid this rejection next year:

The IRS relies on SSA data for identity verification.
