HB 3135 increases Oklahoma's homestead property tax exemption for homeowners. It raises the base exemption from $1,000 to $2,000 per homestead and adds a conditional $3,000 exemption if two conditions are met: (1) a county's ad valorem tax revenue grows by at least 5% compared to the prior year, and (2) the county commissioners approve the additional exemption. This bill directly affects homeowners in counties meeting the revenue growth threshold, effective January 1, 2027. The key mechanism requires both verified revenue growth and local government approval to trigger the higher exemption amount.
