HB 3590, the Oklahoma Opportunity Scholarship Act of 2026, expands tax credits for Oklahoma taxpayers who contribute to scholarship-granting organizations. It increases the maximum annual tax credit: to $5,000 for single filers (up from $1,000), $10,000 for married couples filing jointly (up from $2,000), and $250,000 for businesses (up from $100,000). Taxpayers who commit to contribute the same amount for two consecutive years qualify for a 100% credit (up from 75%) on those contributions. The bill affects Oklahoma taxpayers making eligible contributions and requires scholarship organizations to submit annual financial reports to the Oklahoma Tax Commission. It takes effect January 1, 2027.
Oklahoma's SJR 39 proposes a constitutional amendment to reduce limits on annual increases in property tax assessments. It would lower the maximum annual growth rate for most real property from 5% to 3% (for tax years 2027 onward) and further reduce limits for homestead properties (primary residences) and agricultural land from 3% to 1%. The amendment applies to locally assessed real property, excluding personal property and properties with recent transfers or improvements. If approved by voters, these changes would take effect for tax years beginning in 2027.
HB 4340 would add a sales tax exemption for the sale of "frack water" (wastewater from oil and gas extraction) in Oklahoma. This exemption would directly affect oil and gas companies and vendors selling this wastewater, eliminating the sales tax on such transactions. The bill amends Oklahoma's sales tax code to include this specific exemption under existing tax exemption categories. The policy change would reduce tax burdens for businesses involved in handling oil and gas extraction wastewater. The bill is currently pending in the Appropriations and Budget Natural Resources Subcommittee.
HB 3698 creates the Student Eviction Assistance Revolving Fund within Oklahoma's State Department of Education to address housing instability affecting students. The fund provides legal representation for low-income families (indigent tenants) with children enrolled in pre-K through 12th grade facing eviction (forcible entry/detainer cases), with referrals required through their school district. Funding comes from state appropriations, federal grants, and donations, and is allocated across all 77 counties based on poverty rates and chronic absenteeism data. The bill mandates annual audits of legal service organizations, requires detailed expenditure reports to state leaders, and takes effect November 1, 2026.
HB 2087 modifies Oklahoma's income tax credit for donations to qualified research institutes. It adjusts annual funding caps: for biomedical research institutes, the limit drops from $2 million to $1.5 million per year starting in 2026, while cancer research institute credits are capped at $500,000 annually. The credit percentage for each donation type is recalculated yearly based on prior-year claims, using specific formulas to stay within these new limits. Taxpayers donating to qualifying nonprofit biomedical or cancer research institutes (defined by NIH funding requirements) can claim the credit, with individual limits of $1,000-$25,000 depending on filing status or business type.
