Every year the IRS mails notices and letters to taxpayers for a variety of reasons. Here are a few facts you should know if you receive a notice or letter:

  1. Don’t panic! You can usually deal with a notice simply by responding to it.
  2. 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.
  3. Your notice will likely be about changes to your account, taxes you owe or a payment request or may ask for more information on a specific issue.
  4. If your notice says that the IRS changed or corrected your tax return, review the information and compare it with your original return.
  5. 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.
  6. 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.
  7. Always keep copies of any notices you receive with your tax records.
