California Tax Power of Attorney (Form FTB 3520 PIT)


The California Tax Power of Attorney Declaration (Form FTB 3520 PIT) can be used by any taxpayer in the state who needs to delegate one or more of their taxation matters to another individual or entity (typically an accountant or other tax-handler). The State of California Franchise Tax Board (FTB) provides form 3520 to allow an individual to authorize an Attorney-in-Fact (called the “representative” on the form) to receive confidential information and represent them before the board. Taxpayers should note that the authority granted will generally expire six (6) years after they file the form, but can be terminated earlier at any time through the use of California’s FTB 3520-RVK (Declaration of Revocation). The form permits the principal to add as many representatives as they so choose, in addition to the primary representative. If additional fields are needed, simply print the document as many times as needed and attach all of the forms together.
