WHAT MATTERS
Organize the facts before choosing the tax answer.
These are the parts of the situation most likely to change the work.
Understand the request
Identify what changed, what information is requested and whether a response is required. Do not assume every letter is a penalty or an audit.
Prepare the evidence
Keep the relevant return, statements, payment records and previous correspondence together. Retain the notice and a copy of anything you send.
Get appropriate representation
A disputed amount, examination or appeal can require an authorized professional. Representation and disclosure permissions must be established before someone acts for you.
