What Are IRS Letters and Notices?
The Internal Revenue Service (IRS) sends letters and notices to millions of taxpayers every year. These documents are official communications about your tax account and may cover topics like tax returns you filed, payments you made, refunds, or tax law changes that affect you. Understanding what these letters contain and why you received them is an important part of managing your tax situation.

IRS notices come in different types, each serving a specific purpose. Some letters inform you of changes to your account. Others ask for missing information. Some explain tax law updates or announce changes to tax programs. The IRS sends these documents through the mail—they do not typically contact taxpayers by phone, email, or text message about tax matters, though scammers often pose as the IRS using these methods.
In 2022, the IRS sent over 280 million notices to taxpayers. This high volume means many people receive at least one IRS letter during their lifetime. The letters often contain important information that requires a response within a specific timeframe. Ignoring an IRS notice can result in penalties, interest charges, or collection actions.
Each IRS letter or notice has a specific number, called a notice number or letter number. This number appears near the top of the document and identifies what type of communication you received. For example, a Notice 1219-C refers to a specific type of letter about tax payment options. These numbers help both taxpayers and IRS representatives quickly identify the letter's subject and purpose.
Practical Takeaway: When you receive any IRS letter, do not throw it away or set it aside. Open it promptly, note the letter number and date, and read through the entire document to understand what action, if any, is needed from you.
Common Types of IRS Letters and What They Mean
Several types of IRS letters appear regularly in taxpayer mailboxes. Learning to recognize them helps you understand what the IRS is communicating and what steps you may need to take. The most common categories include notices about refunds, tax payments, missing information, tax changes, and account adjustments.

Notice 1219-C is one of the most frequently sent IRS letters. This notice informs taxpayers about payment options if they owe taxes. It explains that the IRS offers several ways to pay, including payment plans (called "installment agreements"), where you pay over time rather than in one lump sum. The letter describes options like short-term extensions and long-term payment plans. It also provides information about how to set up payments through the IRS website or by phone.
Notices about missing information are also common. If the IRS reviewed your return and found that you did not provide all required documentation or that some information appears incomplete, they send a letter requesting the missing details. These notices typically give you 30 days to respond. For example, if you claimed a home office deduction but did not provide documentation of your expenses, the IRS might request receipts, utility bills, or records showing the square footage of your home office.
Refund-related letters tell you about delays in processing your return or explain why a refund was smaller than expected. The IRS processes millions of returns each filing season. Some refunds take longer to process, especially if the return required additional review or if there was a math error. Other letters explain that part of your refund was used to pay back taxes, child support, or other government debts. The federal government allows the IRS to keep refunds to pay off certain obligations you may have.
Letters about tax law changes inform you that new laws or rules may affect your tax situation. For example, in recent years, the IRS sent notices about changes to retirement account contributions, child tax credits, and earned income tax credits. These educational letters help taxpayers understand how changes in the law affect what they owe or what refunds they may receive.
Practical Takeaway: Keep a file of all IRS letters you receive, organized by year and letter number. This record helps you track your tax history and provides proof of IRS communications if questions arise later.
Understanding Notice Numbers and IRS Document Organization
Every IRS notice has a number assigned to it, and this number tells you important information about the letter's purpose. The notice number system helps the IRS organize its communications and helps you quickly find information about what your specific letter means. Learning to read these numbers saves time and reduces confusion.

IRS notice numbers typically follow a pattern. For example, Notice 1219-C, Notice CP-2000, or Letter 1058-A. The numbers and letters in combination identify the specific type of communication. Notice CP-2000 is a common letter sent when the IRS found differences between information on your tax return and information they received from employers, banks, or other sources. This notice explains the differences and asks for your response. Approximately 3 million to 4 million CP-2000 notices are sent annually.
Letter 1058-A is a balance due notice sent to taxpayers who owe taxes. This letter states the exact amount owed, the tax year it relates to, and the date by which payment should be made. It also explains what will happen if you do not pay, including interest and penalty charges that will be added to your bill.
Notice CP-11 is a notice that your return was received and is being processed. This letter is informational and does not require any action. It simply confirms that the IRS has your return and is working on it.
The IRS publishes a complete guide to notice and letter numbers. You can find this information on the IRS website or request it by phone. When you receive a notice, look for the notice number on the first page, usually in the upper right corner or near the top of the document. Use this number to search for more information about what the letter means and what action you should take.
Different IRS departments issue different notice numbers. The Examination Division (which reviews returns for accuracy) uses different notice numbers than the Collections Division (which follows up on unpaid taxes). The Criminal Investigation Division uses different numbers as well. This system helps the IRS track communications by department and purpose.
Practical Takeaway: Write down the notice number from any IRS letter you receive, then search for that number on the IRS website (IRS.gov) or call the IRS at the phone number listed in the letter to learn more about what it means and what response is required.
How to Respond to IRS Letters and What Deadlines Mean
Most IRS letters include a deadline for response. This deadline is important—responding before the deadline helps you avoid additional penalties and keeps your tax account in good standing. Understanding these deadlines and how to respond is critical for protecting your tax situation.

IRS letters typically give you between 10 and 30 days to respond, depending on the type of notice. Some letters request information, such as receipts or documentation to support deductions you claimed. Others ask you to agree or disagree with changes the IRS proposes to your return. If you do not respond within the timeframe given, the IRS assumes you agree with what the letter proposes, and they proceed with adjustments to your account. This can result in additional taxes owed, penalties, and interest charges.
The deadline listed in the letter is the date by which the IRS must receive your response. This means you should send your response several days or weeks before the deadline to allow time for mail delivery. If you respond close to the deadline and your letter is delayed in the mail, you might miss the deadline. To be safe, send your response at least one week before the deadline, or contact the IRS before the deadline if you need more time.
When responding to an IRS letter, always include the notice number, your name, address, and Social Security number or Employer Identification Number (EIN) if you are a business. Follow the specific instructions in the letter about where to send your response and what documents to include. Some letters ask you to send information to a specific IRS address, while others may provide a phone number to call.
If you need more time to gather information or prepare your response, contact the IRS before the deadline. You may be able to request an extension. The IRS is sometimes willing to extend deadlines if you have a good reason, such as waiting for documents from a third party or dealing with a personal emergency. Requesting an extension in writing before the deadline is better than requesting one after the deadline has passed.
If you disagree with what an IRS letter proposes, most letters explain your appeal rights.
