HJR 154 proposes a constitutional amendment that would allow local governments, such as cities and counties, to adopt a residence homestead exemption for ad valorem taxation, expressed as a fixed dollar amount rather than a percentage of a home’s market value. The exemption amount for 2026 is capped at $100,000, with future adjustments based on inflation, as determined by the Consumer Price Index (CPI-U). The Texas Comptroller will calculate and publish the adjusted exemption amount annually. The amendment also permits the Texas Legislature to prohibit local governments from reducing or repealing an adopted exemption. If approved by voters in the November 4, 2025, election, the amendment would take effect for the 2026 tax year and include a temporary provision set to expire on January 1, 2027​.
