Who this service is for

For clients who received an IRS letter or notice and need to understand which return or issue it concerns, what the IRS is asking for, and whether a response deadline applies. A notice should not be evaluated only by its heading or by an amount shown on the first page.

Common situations

  • The IRS asks for support or clarification of an item on the return.
  • The notice proposes a change to income, a credit, or another reported amount.
  • The client is unsure whether a response is needed or what documents to gather.
  • A follow-up notice arrives about an issue that was already discussed with the IRS.

What to prepare

The general checklist covers basic documents and supporting records. This page lists only the documents relevant to this service.

  • A complete copy of the IRS notice, including all pages and attachments.
  • The tax return for the year referenced in the notice.
  • Income forms and other records connected with the issue described in the letter.
  • Earlier correspondence with the IRS about the same matter, if any.

General document checklist

What we review

We read the notice in full, identify the tax year and issue, and compare it with the filed return and the client’s records. That makes it possible to identify what information is missing and what next step is practical.

Some notices require only a review or clarification, while others may require supporting documents or a separate response. The specific content and deadline of the notice matter more than the general notice category.

What to do if you receive an IRS letter

An IRS letter does not always mean something is wrong, but it should not be ignored. First, identify what is being requested and what deadline applies.

Prior-year returns and amended returns

Sometimes a prior-year return needs to be filed, or a return that was already filed needs to be corrected. These are different situations and require different records.

How it works

Common questions

Can I contact you about an IRS letter?

Yes. You can start with an initial review of the IRS notice. We will look at what is being requested, the response deadlines, and which documents may be needed. If the issue is outside the scope of an initial review or requires separate professional representation, we will say that in advance.
