What to Do When You Receive an IRS Notice

Start With the Notice Number, Tax Period, and Deadline

Locate the notice or letter number, usually shown near the top right of the first page. Then record the tax form, tax year or quarter, response date, proposed balance, and IRS contact unit. A CP2000 underreporter notice follows a different process from a CP14 balance-due notice, a correspondence audit, or a final collection notice.

Use the deadline printed on the notice rather than a generic internet timeline. Some dates preserve appeal or Tax Court rights that cannot be restored by a phone call after they expire. The IRS maintains an official notice and letter lookup, but the document in your hand controls the requested action.

• Notice or letter number and the page showing the response address
• Taxpayer name, entity name, and taxpayer identification number shown
• Tax form and every tax period covered
• Exact response, appeal, payment, or petition date
• Whether the notice says proposed, assessed, final, intent to levy, or notice of deficiency

Verify the IRS Version of the Account

Compare the notice with the filed return, source documents, payments, and prior correspondence. An account transcript can show return processing, assessments, payments, credits, penalties, and certain notice activity. A wage and income transcript can reveal Forms W-2, 1099, 1098, and K-1 information reported under the taxpayer's identification number.

Transcripts are evidence, not a complete explanation. They may omit basis, business expenses, corrected forms, correspondence still being processed, and documents filed under a related entity. Obtain records through the IRS Get Transcript service or through an authorized representative before choosing a resolution path.

Choose the Response That Matches the Procedural Stage

A response may agree, partially agree, disagree, provide missing documents, request an appeal, correct a return, request penalty relief, or arrange payment after the tax is final. These actions are not interchangeable. Filing an amended return does not automatically answer every notice, and applying for a payment plan does not dispute an incorrect assessment.

Address each item separately. If one adjustment is correct and another is not, explain both instead of checking a broad box without a reconciliation. Preserve proof of what was sent, where it was sent, and when it was delivered.

• Use the response form and submission method stated in the notice
• Send copies of evidence unless the IRS specifically requests an original
• Label supporting documents and tie each document to a disputed item
• Keep the complete response package and delivery confirmation
• Continue monitoring the account until the IRS confirms the outcome

Know When Representation Changes the Risk

Professional representation is most valuable when the notice involves several periods, missing returns, business payroll, a large proposed adjustment, inconsistent records, an audit, a levy or lien warning, or a deadline tied to appeal or Tax Court rights. An Enrolled Agent can obtain transcripts, evaluate the procedure, prepare a written response, and communicate with the IRS under Form 2848 within the authorized scope.

The IRS publishes the Taxpayer Bill of Rights, including rights to be informed, challenge the IRS position, appeal in an independent forum, finality, privacy, and representation. A representative does not erase deadlines, but can help use the correct procedural right while it remains available.

After the Response: Track, Reconcile, and Escalate Deliberately

IRS processing can take time. Do not assume silence means acceptance. Track delivery, save call notes, and compare each follow-up letter with the response already submitted. If the IRS asks for more evidence, answer the new question without abandoning the original explanation.

When the tax is correct but cannot be paid in full, move from liability review to a collection option such as an IRS payment plan. If penalties are the remaining issue, evaluate penalty relief. If returns are missing, establish filing compliance before expecting a lasting collection resolution.
