What does this mean to me?

Letters 566-B is an Initial Contact Letters (ICL) notifying you that your tax return is being examined and informing you on the enclosed examination report Form 4549, Report of Income Tax Examination Changes, the potential outcome of the audit if you don’t provide information supporting the items in question.  These letters give you 30 or 45 days to provide the requested information or request a conference with the IRS Independent Office of Appeals if you disagree with the proposed changes to your tax return.

How did I get here?

The IRS accepts most tax returns as they are filed. However, the IRS selects some tax returns for additional review or audit to determine if you reported your income, expenses, and credits accurately. If the IRS selects your return for audit (also called examination), it doesn’t automatically mean something is wrong. Once the IRS completes the examination, it may accept your return as filed or propose changes. These changes may affect the amount of tax you owe (a proposed deficiency) or your refund amount.

Read the letter and follow the instructions

If you agree with the IRS’s proposed changes, sign the enclosed examination report and return it to the IRS (keep a copy for your records).


Important: If you don’t agree with some or all the proposed changes, make sure you inform the IRS in writing by the due date on the letter. Your response could include sending additional documentation or an explanation to support your position. Don’t send original documents – send copies. If you fax the information, include your name and taxpayer identification number on each page. This will help the IRS associate the documents with your file. If you need more time to submit your information, call the number on the letter before the due date to ask for additional time. If you are uncertain about what information to provide, call the number on your letter, write to the IRS at the address shown on the letter, or make an appointment to visit your local IRS Taxpayer Assistance Center.

You may also request an informal conference with the examiner’s manager. To preserve your right to a conference with the IRS Independent Office of Appeals, request an Appeals conference prior to the response date in the letter.
