Tax information authorization TIA

Overview

A tax information authorization gives that person the legal right to review some confidential taxpayer information.

A TIA relationship does not allow the representative to act on a taxpayer’s behalf to resolve their tax issues with FTB. For the right of the representative to act on their behalf, a taxpayer needs to file a Power of Attorney (POA) Declaration. Visit Power of attorney vs. tax information authorization for more information.
