Getting a letter from the IRS can feel scary, but many notices are easy to handle. The IRS may send a notice to ask for information, explain a change, or request payment. Read the full letter before taking action.

Start by checking the notice number. It often begins with “CP” or “LTR” and appears near the top or right side of the page. This number tells you what the letter is about. You can search for it on the IRS website.

Next, check your name, tax year, and Social Security number. Compare the notice with your tax return, W-2 forms, 1099 forms, receipts, and payment records. The IRS can make changes because of a math error, missing income, or a payment that was not recorded.

Common notices include CP14, which shows unpaid taxes, and CP2000, which reports income that may not match your tax return. A CP2000 is not a bill. It is a proposed change. Review the details before agreeing or sending money.

Pay close attention to the response date. Some notices do not require a reply. If the IRS asks you to respond, follow the instructions and send your answer by the deadline. Keep copies of the notice, your reply, and all supporting papers. When mailing a response, use the address printed on the notice.

If you agree with the notice, pay the amount due or follow the listed steps. If you cannot pay in full, you may be able to request a payment plan. If you disagree, explain why and include copies of records that support your answer. Do not send original documents unless the IRS asks for them.

Watch out for scams. The IRS usually makes first contact by mail. Be careful with texts, emails, or social media messages that demand fast payment or personal details.

You can also check your IRS online account to confirm balances, payments, and notices.

An accountant can help you understand the notice and prepare a clear reply. Getting help early may prevent extra interest, penalties, or missed appeal rights. The most important step is simple: do not ignore the letter.
