(a) A warrant may not be prepared unless a properly audited claim, verified as to correctness by the agency submitting the claim, is presented to the warrant clerk.
(b) A claim may not be paid from an appropriation unless the claim is presented to the comptroller for payment not later than two years after the end of the fiscal year for which the appropriation was made. However, a claim may be presented:
(1) not later than four years after the end of the fiscal year for which the appropriation from which the claim is to be paid was made if the appropriation relates to:
(A) new construction contracts;
(B) grants awarded under Chapter 391, Health and Safety Code;
(C) repair and remodeling projects that exceed the amount of $20,000, including furniture and other equipment and architects’ and engineering fees; and
(D) other costs related to the contracts or projects; or
(2) not later than seven years after the end of the fiscal year for which the appropriation from which the claim is to be paid was made if the appropriation relates to grants awarded under Chapter 102, Health and Safety Code.

(c) A claim not presented before the deadline provided by Subsection (b) may be presented to the legislature as other claims for which appropriations are not available.
(d) A warrant may not be drawn against an appropriation from a special fund or account unless the fund or account contains in the state treasury sufficient cash to pay the warrant. The comptroller may not release or deliver a warrant unless the appropriation against which the warrant is drawn has a balance sufficient to pay the warrant.
(e) As a claim is paid it shall be filed according to the method the comptroller finds most advisable. After two years after a claim is filed, it shall be removed from the files and stored as a record.
(f) A person commits an offense if the person knowingly makes a false certificate on a claim against the state for the purpose of authenticating a claim against the state. An offense under this section is punishable by imprisonment in the Texas Department of Criminal Justice for not less than two or more than five years.
(g) Notwithstanding Subsection (a), the comptroller may audit claims presented by the state agency after the comptroller prepares warrants or uses the electronic funds transfer system to pay the claims.
(h) The comptroller may establish requirements and adopt rules concerning the time that a state agency must retain documentation in its files to enable a postpayment audit. If a postpayment audit by the comptroller shows that a claim presented by a state agency was invalid, the comptroller may:
(1) implement procedures to ensure that similar invalid claims from the state agency are not paid in the future;
(2) report to the governor, the lieutenant governor, the speaker of the house of representatives, the state auditor, and the Legislative Budget Board the results of the audit;
(3) require the state agency to obtain a refund of the monies from the payee; and
(4) reduce the state agency’s remaining appropriations by the amount of the claim.
(i) The comptroller may access the books, accounts, confidential or nonconfidential reports, vouchers, electronic data, or other records or information of a state agency subject to a postpayment audit. If information may not be released under federal law, the comptroller may not access the information without approval of the appropriate federal agency.
(j) The comptroller shall use reasonable efforts to avoid hindering the daily operations of a state agency subject to a postpayment audit by coordinating requests for access to books, accounts, reports, vouchers, electronic data, or other records or information of the audited agency.
