Identify the document

Find the CP or LTR number and look it up in the official IRS notice library. Record the tax period, amount, action requested, and response deadline.

Different letters can concern balances, return adjustments, refunds, identity checks, or other account matters. Do not infer the required action from the envelope alone.

Your focused reading: Returns in different places

Put this into practice.

Records often live across paper folders, software accounts, and old email. Start with a simple year-by-year index. Note where each return and supporting record is stored so a later review does not depend on memory.

  • Create a list of relevant years
  • Identify each record’s location
  • Separate complete and incomplete years
  • Use secure methods to retrieve sensitive files

Compare the records

Keep all pages and compare the notice with the relevant return, payment records, and earlier correspondence. Write down the precise figure or statement you need clarified.

A timeline can show what happened before and after a letter. Keep supporting records together so the issue can be reviewed without relying on memory.

Respond as instructed

If a response is requested, follow the stated instructions and date. If you disagree, use the described dispute procedure and include relevant evidence. Some notices do not require a reply.

Preserve the response and delivery evidence. Use the specific deadline on your letter rather than a general timeline found on a website.

Know what a referral call does

A call to the Republic Tax referral line can start a service discussion. It is not a response to the IRS, a payment, or an extension of a deadline.

When contacting the IRS, use verified official channels and the contact instructions on the letter. Confirm the identity of a private recipient before sharing tax records.
