Error

The taxpayer identification number (TIN) on your return was already used on another accepted return for this tax year.

Solution

Review the taxpayer's TIN on your return.

For a given tax year and return type, a taxpayer's TIN can be used on only one accepted electronic return.

  • Verify that the TIN is entered correctly.
  • If you have already filed a return for this tax year, do not file another original return. File an amended return if changes are needed.
  • If you did not file a prior return and believe the TIN was used without your permission, contact the IRS for guidance on possible identity theft.

After resolving the issue, resubmit only if appropriate.
