The Mississippi tax power of attorney (Form 21-002-13) is a document that grants taxpayers the ability to authorize a representative to act on their behalf with respect to the tax matters relayed in the document. This form allows the taxpayer to appoint up to three (3) individuals to represent them before the Mississippi Department of Revenue. The chosen representative may represent the taxpayer regarding several tax types such as personal income tax, franchise tax, sales tax, and insurance premium tax.  If a tax matter is regarding a joint return, both spouses must sign that document. A principal officer and a secretary must sign this form if it is completed on behalf of a corporation or subsidiary.
