A Texas Tax Power of Attorney (Form 85-113) must be filled out to designate someone to represent you in tax matters that concern you before the Texas Comptroller of Public Accounts. This power of attorney grants the person you appoint the power to see your tax information and make filings and decisions on your behalf. Once this document has been submitted, approved, then placed in effect the person you name as your representative will be able to carry out the functions expected of him or her so long as they have been clearly authorized in this paperwork. Naturally, it will be imperative that any agent given authority in such matters should be one who is both qualified and reliable to act in this capacity.
