Oklahoma voters are officially on the hook to decide how fast their property tax bills can climb. Lawmakers have approved a constitutional amendment on property tax growth limits and set a special statewide election for Aug. 25, 2026. If voters sign off, the new caps on yearly increases in assessed value would start applying in tax year 2027.
What SJR 39 would change
Under the House floor substitute for SJR 39, annual growth in taxable value would be dialed back in two major categories. For homestead property and agricultural land, the current 3 percent cap on assessed value increases would drop to 1.75 percent. For all other real property, the cap would fall from 5 percent to 4 percent.
The resolution also scraps the current flat “senior freeze” and replaces it with a tiered, income based system tied to U.S. Department of Housing and Urban Development county median income. Seniors in the lowest income tier would see no annual increase at all, while higher income tiers would see gradual hikes up to the standard 1.75 percent cap. The specific income brackets and timing details are laid out in the Oklahoma House floor summary, according to the Oklahoma House of Representatives.
How the proposal changed in the Legislature
The plan that landed on the ballot is not the one that first cleared the Senate. An earlier version approved in that chamber would have set a 3 percent cap for most property and a tighter 1 percent cap for homesteads. Legislative records show that language in the engrossed Senate version and track how the measure moved before the House rewrote it on the floor.
Representatives adopted their substitute, then passed the revised SJR 39 on April 15 and sent it on for engrossment. The earlier text is available through LegiScan, and the timeline of the bill’s journey has also been detailed by the Journal Record.
Supporters and critics
House Speaker Kyle Hilbert has pitched the measure as a point of pride, saying it would give Oklahomans “the lowest fixed rate cap on personal property in the nation” and arguing that tighter limits are needed to shield homeowners from sharp spikes in valuation.
Critics see a different risk. County officials and education advocates warn that squeezing assessed value growth could choke off local revenue, which might mean leaner services or pressure to raise money in other ways. Those fiscal concerns have surfaced in coverage of the broader package of ad valorem measures headed for the Aug. 25 ballot, as reported by KOSU.
Next steps for voters and local officials
SJR 39 formally calls a special election for Aug. 25, 2026, to put the proposal in front of voters statewide. If it passes, the change would be written into the Oklahoma Constitution and start affecting property valuations beginning with tax year 2027.
The resolution instructs officials to file the ballot title with the Secretary of State and the Attorney General. Legislative materials also note that lawmakers will need to pass implementing statutes, while counties and school districts will have to work the possible new caps into their revenue projections ahead of the vote, according to the Oklahoma Legislature.
