Letter to the IRS (response to a notice)

When an IRS notice asks you to respond by mail, send your reply to the address printed on the notice and include the notice number, tax year and your taxpayer ID. Certified Mail gives you a postmarked receipt that shows when you mailed it.

Recommended: Certified + return receipt ($17.99)The IRS treats many documents as filed on the postmark date, and a certified mail receipt is the standard evidence of that date.

When to use this letter

  • Responding to a CP or LTR notice that asks for a written reply
  • Sending documents the IRS requested
  • Disagreeing with a proposed change and explaining why

Where to send it

Use the exact IRS address printed on your notice (often in the top corner or on the response form).

Tips before you mail it

  • Include a copy of the notice (upload it as a PDF page) so the IRS can match your reply.
  • Never write your full SSN in the letter body if it isn't needed; the last four digits plus the notice usually identify you.
  • We can't enclose checks. If you owe, pay through IRS Direct Pay or another IRS payment option.
  • Respond by the date on the notice; if you can't, contact the IRS at the number on the notice.
