Texas Tax Code - TAX § 26.051. Evidence of Unrecorded Tax Rate Adoption

(a) If a taxing unit does not make a proper record of the adoption of a tax rate for a year but the tax rate can be determined by examining the tax rolls for that year, the governing body of the taxing unit may take testimony or make other inquiry to determine whether a tax rate was properly adopted for that year. If the governing body determines that a tax rate was properly adopted, it may order that its official records for that year be amended nunc pro tunc to reflect the adoption of the rate.

(b) An amendment of the official records made under Subsection (a) of this section is prima facie evidence that the tax rate entered into the records was properly and regularly adopted for that year.
