What to check before you answer
Is this letter really from the IRS?
The IRS writes first by mail. A real letter shows a notice or letter number, your name and part of your tax ID number. The IRS does not ask for payment by gift card, crypto or wire transfer. If in doubt, sign in to your IRS online account, where many notices are listed.
Common questions

If it’s been over 10 weeks since you sent us the return, send a signed copy of it to us again.
What if I had no employees during the tax period shown on the notice?
Please contact us at the toll-free number listed in the notice with that information.
