Before calling the IRS

The IRS says representatives generally need to verify identity before discussing personal information. Individual callers should be prepared with Social Security or taxpayer identification numbers, birth dates, filing status, and a prior-year tax return. The correct preparation depends on who is calling and whose account is involved.

If the IRS has asked you to wait for correspondence or processing, its current guidance may recommend checking published processing times instead of calling or filing a duplicate submission.
