Relating to the deadlines for performing various functions in connection with the ad valorem tax system.

HB 416 adjusts deadlines for property tax processing in Texas. It moves key dates from August to July, requiring chief appraisers to certify tax rolls by July 25 and estimate taxable values by July 20 if review boards miss deadlines. Taxing units (like cities and counties) must submit tax rolls and rates to governing bodies by July 1 or July 7, depending on the section. The bill affects appraisers, assessors, collectors, and taxing unit officials who manage property tax administration. It is procedural, changing only timing requirements without altering tax rates or calculations.
