Each year, the IRS mails millions of notices and letters to taxpayers for a variety of reasons. If you receive correspondence from them:

Don’t panic. You can usually deal with a notice simply by responding to it.

Most IRS notices are about federal tax returns or tax accounts. Each notice has specific instructions, so read your notice carefully because it will tell you what you need to do.

Your notice will likely be about changes to your account, taxes you owe or a payment request. However, your notice may ask you for more information about a specific issue.

If your notice says that the IRS changed or corrected your tax return, review the information and compare it with your original return.

If you agree with the notice, you usually don’t need to reply unless it gives you other instructions or you need to make a payment.

If you don’t agree with the notice, you need to respond. Write a letter that explains why you disagree, and include information and documents you want the IRS to consider. Mail your response with the contact stub at the bottom of the notice to the address on the contact stub. Allow at least 30 days for a response.

For most notices, you won’t need to call or visit a walk-in center. If you have questions, call the phone number in the upper right-hand corner of the notice. Be sure to have a copy of your tax return and the notice with you when you call.

Always keep copies of any notices you receive with your tax records.

Be alert for tax scams. The IRS sends letters and notices by mail. They don’t contact people by email or social media to ask for personal or financial information. If you owe tax, you have several payment options. The IRS won’t demand that you pay a certain way, such as prepaid debit or credit card.
