Texas Form 00-812 serves as a standardized financial security instrument provided by an issuing financial institution on behalf of a taxpayer to the Texas Comptroller of Public Accounts. Under Texas tax statutes, businesses operating in regulated sectors or handling significant recurring tax collections must post continuous collateral to secure payment of all state taxes, statutory fees, penalties, and interest that may accrue under the law. Rather than tying up working capital through cash deposits or purchasing commercial surety bonds, businesses frequently arrange for their depository bank to establish an irrevocable letter of credit. Form 00-812 legally binds the issuing financial institution to honor demand drafts drawn by the Comptroller up to a designated dollar threshold upon presentation of an official payment demand notice. Submitting this form guarantees statutory compliance, secures mandatory commercial permits, and protects state revenue accounts while providing businesses with an established, credit-backed alternative for satisfying collateral requirements.
How To File Form 00-812
Taxpayers submit this irrevocable letter of credit directly to the Texas Comptroller of Public Accounts as a condition of issuing or maintaining their commercial tax permits. Because this document represents a binding third-party commitment, the financial institution issuing the letter of credit must fill out the core bank authorization terms, assign a unique instrument number, and execute the certification through an authorized corporate officer before filing.
Gather the following items before completing the form:
- Your active eleven-digit Texas Taxpayer Number or pending license application paperwork.
- The precise legal business entity name registered with the Texas Secretary of State and Comptroller.
- The official dollar amount of tax security required by the Comptroller for your specific tax license.
- Your issuing bank’s legal name, branch address, and Federal Employer Identification Number.
- The exact letter of credit number and expiration terms established by the financial institution.
Once the financial institution has executed the form, submit the original document alongside your tax permit application or forward it directly to:
Comptroller of Public Accounts
111 E. 17th Street
Austin, TX 78774-0100
The Comptroller retains the original letter of credit in state custody throughout its effective period or until replaced by an approved alternate security vehicle.
