Responding to a Tax Notice

Before you respond

What to do when an IRS or state tax notice arrives.

A notice is a request, proposed change, balance, or other agency communication—not a complete explanation of what happened. Start by identifying the agency, notice number, tax period, deadline, and requested action.

Read every page, verify that the notice is authentic, note the response deadline, identify the tax period and proposed action, compare it with the filed return and records, and avoid sending sensitive documents through ordinary email or a consultation form.

01

Identify exactly what arrived

Different notices can involve math changes, missing returns, information matching, identity verification, balances, collection, audits, penalties, or state-specific issues.

Agency name, notice or letter number, issue date, response deadline, tax form, tax year or period, and taxpayer name.
Proposed balance, adjustment, missing item, requested document, hearing or appeal right, and payment instructions.
Whether the notice is the first communication or follows an earlier notice, return, payment, audit, or identity issue.
The address, fax, portal, or other response method printed on the notice.
Signs of fraud: unusual payment demands, unofficial links, threats, or requests inconsistent with official agency practices.
Keep in mind: Use the phone number or account portal from an independently verified official agency source if authenticity is uncertain.

02

Compare the notice to the tax record

A notice may be correct, partly correct, or based on missing or mismatched information.

Locate the filed return, e-file acceptance, extension, payment confirmations, and prior correspondence for the period.
Trace the notice amount or item to the return line, form, schedule, account transcript, payroll report, or information statement involved.
Identify corrected forms, amended returns, identity issues, duplicate income, missing basis, misapplied payments, or state/federal differences.
Create a dated timeline of filings, payments, calls, letters, portal messages, and delivery confirmations.
Preserve original documents; prepare copies and a response index rather than mailing irreplaceable records.
Keep in mind: Do not file an amended return or make an unsupported payment solely because a notice arrived. First determine the correct procedural response.

03

Choose the response path

The next step depends on the notice, deadline, facts, amount, documentation, and available procedural rights.

If correct: confirm the amount, payment method, deadline, and whether other periods or returns are affected.
If incorrect or incomplete: prepare a focused written response tied to the notice and supporting records.
If more time is needed: determine whether the agency permits an extension or other procedural request before the deadline.
If the matter involves an audit, collection, appeals right, missing returns, identity issue, large balance, or multiple periods: consider professional representation promptly.
Keep a complete copy of the response and proof of timely delivery or electronic submission.
Keep in mind: Submitting a consultation request does not extend an agency deadline or create representation.

04

Protect sensitive information and follow through

Use secure channels and continue monitoring until the agency records the response and resolves the matter.

Redact unnecessary account or identity information from working copies.
Use the agency’s verified portal or a secure document process requested by the representative.
Do not attach notices, returns, Social Security numbers, bank details, or account numbers to a general consultation form.
Calendar the expected response window and check transcripts, account status, or new mail as appropriate.
Escalate if collection, levy, lien, default, petition, appeal, or other rights may expire.
Keep in mind: No professional can guarantee an agency outcome. Results depend on facts, law, records, procedure, timing, and agency action.

Sources and limits

Verify current rules before acting.

This guide does not replace advice about a specific notice and does not create representation. Deadlines and rights vary by agency and notice. Verify the current official instructions printed on the notice and with the issuing agency.

Should I call the number on the notice?

First verify that the notice is authentic and gather the return, payment, and records for the period. A call may be appropriate, but keep notes and understand the issue before making statements or agreements.

Should I pay the amount to stop interest?

That depends on whether the amount is correct, the procedural options, cash flow, and the type of matter. A payment can have consequences; review the notice and facts before acting.

Can I upload the notice with a consultation request?

No. Describe the agency, notice number, tax period, deadline, and issue at a high level. Use secure upload only after the team requests the document.

Does requesting a consultation pause the deadline?

No. A form submission does not extend a deadline, create an engagement, or establish representation. Preserve the agency deadline while fit and scope are reviewed.
