The Internal Revenue Service sends out
millions of letters and notices to taxpayers every tax year. That
doesn’t mean taxpayers should be alarmed. Here are eight tips about
dealing with an IRS notices, if one should arrive in your mailbox.
Don’t panic. Many of these letters can be dealt with simply and
painlessly.

1. There are a number of reasons the IRS sends notices to
   taxpayers. The notice may request payment of taxes, notify you of a
   change to your account or request additional information. The
   notice you receive normally covers a very specific issue about your
   account or tax return.
2. Each letter and notice offers specific instructions on what you
   need to do to satisfy the inquiry.
3. If you receive a correction notice, you should review the
   correspondence and compare it with the information on your
   return.
4. If you agree with the correction to your account, usually no
   reply is necessary unless a payment is due.
5. If you do not agree with the correction the IRS made, it is
   important that you respond as requested. Write to explain why you
   disagree. Include any documents and information you wish the IRS to
   consider, along with the bottom tear-off portion of the notice.
   Mail the information to the IRS address shown in the lower left
   part of the notice. Allow at least 30 days for a response.
6. Most correspondence can be handled without calling or visiting
   an IRS office. However, if you have questions, call the telephone
   number in the upper right corner of the notice. Have a copy of your
   tax return and the correspondence available when you call.
7. It’s important that you keep copies of any correspondence with
   your tax records.
