Nothing can make your blood run cold more than receiving a letter from the IRS. There are about 75 different IRS notices and letters.

How to Identify the Letter from the IRS
The IRS assigns a number to every notice that leaves their office. It helps IRS employees track correspondence from thousands of citizens. Some notices come with a CP designation. The IRS prints the CP (Computer Paragraph) at the top of the notice's first page. A corresponding CP number also appears on the removable portion of the page. This helps users keep a portion of the notice for their records. The IRS usually places the CP number in the notice header, at the top center of the page.
What to Do if You Receive a Letter from the IRS
Most letters from the IRS contain specific instructions to help complete your tax return. Each notice or letter will require some action on your part. After reviewing mail from the IRS, it is essential to compare the information received from the IRS to the information that you provided to them during the period in question. If there is a discrepancy, bring it to their attention. If you made an error and need to make an additional payment, you can send correspondence and payment directly to the address on the notice. When submitting any information to the IRS or to any company for that matter, it is good practice to keep copies for your own records.
