The IRS's Independent Office of Appeals that handles a taxpayer's case must be separate from the IRS office that initially reviewed that case. Generally, Appeals will not discuss a case with the IRS to the extent that those communications appear to compromise the independence of Appeals.

Taxpayers have the right to receive a written response regarding a decision from the Office of Appeals.
