Why Would the IRS Send You a Letter

Why the IRS Sends Letters

The IRS sends letters to millions of taxpayers every year for reasons ranging from simple balance-due notices to complex audit requests. Most letters are routine administrative actions tied to tax returns, account updates, or compliance checks, not signs of criminal investigation. Understanding why the IRS would send you a letter starts with knowing the common categories of correspondence.

Common Reasons for an IRS Letter

• Balance due or refund adjustment — The IRS calculates a different tax liability than you did, or your refund was changed after review.
• Identity verification — Suspicious filings or data-matching flags trigger a request to confirm your identity using Form 14039 or similar documentation.
• Information request — The IRS needs additional documentation, such as W-2s, 1099s, or receipts, to verify items on your return.
• Audit notification — You are selected for an audit, either by correspondence or in person, based on discrepancy or random selection.
• Collection action — Unpaid taxes have been referred to the Automated Collection Service or a local IRS office for resolution.
• Refund delay — Your return is under review, which can happen with earned income tax credits, additional child tax credit, or other flagged items.

What to Do When You Receive a Letter

Read the notice carefully. Each IRS letter includes a specific notice number, the tax year involved, and instructions on how to respond. Compare the information in the letter to your original return. If the letter requests payment, respond by the deadline even if you disagree; you can file a petition later. For identity verification or information requests, provide only what is asked and keep copies of everything you send.

How to Verify an IRS Letter Is Legitimate

The IRS will never demand immediate payment via gift cards, prepaid debit cards, or wire transfers. A legitimate notice will reference an official IRS.gov notice number, include a response deadline, and provide a way to contact the agency through official channels. Use the IRS letter lookup tool at IRS.gov to confirm the notice is valid before taking any action.

When to Get Professional Help

Consider a tax professional if the letter involves an audit, a large balance adjustment, or complex issues like business income, international reporting, or penalty abatement. A CPA or enrolled agent can help you respond accurately and protect your rights, especially when the IRS is requesting records that could expand the scope of the inquiry.
