Don't panic. A step-by-step guide on how to respond effectively and professionally to correspondence from the IRS. Opening your mailbox to find a letter from the Internal Revenue Service is enough to spike anyone's heart rate. However, it is crucial to remain calm. The vast majority of IRS notices are not audits — they are automated requests for clarification, notifications of a mathematical error, or statements of a balance due. The single most important rule when receiving any IRS correspondence: do not ignore it. Ignoring an IRS notice escalates the situation and accrues penalties and interest. Common Types of IRS Notices The IRS issues hundreds of different notice types, each identified by a 'CP' or 'LTR' number printed in the upper right corner of the letter. The most common notices small businesses and individuals receive include: CP2000 (income underreporting — the IRS's records don't match yours), CP501 through CP503 (balance due reminders), CP504 (intent to levy — this one requires urgent action), and Letter 525 or Letter 950 (audit notification). Your first step is always to read the notice fully and identify the notice type. Many CP notices are generated automatically by IRS computers without any human review. A CP2000, for example, simply means the IRS received a 1099 or W-2 that did not appear on your return. This is frequently caused by a data entry error, a missing form, or income that was reported in a different place on your return than the IRS expected. It is a discrepancy notice — not an accusation of fraud. CP2000: Income or credit discrepancy — the most common notice CP501 / CP503: Balance due reminder CP504: Intent to levy — urgent, respond within 30 days Letter 525 / Letter 950: Office audit or examination notice Letter 2205: Initial contact letter for a field audit CP90 / CP297: Final notice of intent to levy (seize assets) First Steps After Receiving the Notice Read the entire notice before doing anything else. Identify the notice type, the tax year in question, the amount (if any) the IRS claims is owed, and the response deadline. Most notices require a response within 30 or 60 days from the date printed on the letter — not from when you received it. If the notice arrived late due to a forwarding delay or was sitting unopened, contact the IRS immediately to explain and request a deadline extension. Pull your tax return for the year in question and compare it against the IRS's claims. If the notice is a CP2000, check whether the income the IRS is referencing actually appears on your return — sometimes in a different line or schedule than the IRS's matching system expected. Gather all documentation related to the issue: the 1099 or W-2 in question, your original return, and any supporting schedules. When You Agree with the Notice If the IRS's notice is correct — for example, you genuinely forgot to report a 1099 income amount or made a math error — the resolution is straightforward. Pay the amount owed by the due date to stop interest from accruing. You can pay online at irs.gov/payments via IRS Direct Pay, EFTPS, or credit/debit card (note: card payments incur a convenience fee). If you cannot pay in full, contact the IRS to arrange an installment agreement before the deadline to avoid a Notice of Federal Tax Lien. Even when you agree with the IRS, you may be able to request penalty abatement — a reduction or elimination of penalties assessed on the balance — if you have a history of timely compliance and the failure was due to reasonable cause. First-time penalty abatement is available to taxpayers with no penalty history in the prior three years. Your CPA can draft a penalty abatement request as part of your response. When You Disagree with the Notice If you believe the IRS is wrong, you have the right to dispute the notice — but you must respond in writing by the deadline, providing documentation to support your position. Calling the IRS is useful for getting information, but phone conversations do not constitute a formal response and create no official record. Your dispute must be in writing, sent by certified mail with a return receipt, addressed to the address on the notice. Your written response should include: the notice number and tax year, a clear statement that you disagree and why, copies (never originals) of all supporting documentation, your contact information, and the taxpayer's signature. Keep a copy of everything you send. The IRS typically takes 30 to 90 days to respond to a dispute. If you are disagreeing with a CP2000, the IRS will issue a Statutory Notice of Deficiency if your dispute is not accepted — at which point you have 90 days to petition the U.S. Tax Court. When to Hire Professional Representation If the notice involves an audit, a levy, a lien, a significant amount owed, or a dispute with complex facts, engaging a CPA, Enrolled Agent (EA), or tax attorney immediately is strongly advisable. These professionals have the authority to represent you directly before the IRS under a Form 2848 Power of Attorney, meaning the IRS communicates with them — not you — throughout the process. Professional representation matters not just for the expertise it brings, but for the tone it sets. Taxpayers who represent themselves often volunteer information that expands the scope of an inquiry or agree to positions they did not have to accept. A tax professional experienced in IRS representation knows what to provide, what not to volunteer, and how to negotiate efficiently. Time spent responding to an IRS notice is also time not spent running your business — that cost is real.
