SB 301 modifies Oklahoma's tax credit system for donations to biomedical and cancer research institutes. It reduces annual credit limits to $1.5 million for biomedical research donations and $500,000 for cancer research donations starting in 2026, down from $2 million previously. Donors to qualifying institutes (which must receive $20 million annually in NIH funding for biomedical or $4 million for cancer research) will face new caps: $25,000 for business donors to biomedical institutes, and $1,000-$2,000 for individual filers depending on filing status. The bill adjusts how credit percentages are calculated using the second preceding year's claims and ensures credits cannot exceed tax liability.
HB 1200 establishes a revenue stabilization mechanism for Oklahoma's state budget. It requires the State Board of Equalization to certify five-year average revenue from oil, natural gas, and corporate income taxes. If annual revenue exceeds these averages, specific percentages (25% to the Constitutional Reserve Fund, 75% to the Revenue Stabilization Fund) must be deposited - unless revenue growth exceeds $400 million (adjusted for inflation), which could trigger future tax rate reductions. The bill does not change tax rates directly but links fund deposits to revenue performance, affecting how state funds are managed rather than individual taxpayers. This procedural bill focuses on budget stability rules, not new tax policies.
HB 1372 temporarily lowers the gross production tax rate for oil and gas from existing wells (spudded before the law's effective date) to 5% for 36 months, instead of the standard 7%. It also creates two new tax exemptions: 1) 5 years of tax-free production for secondary/tertiary recovery projects approved after July 2022, and 2) a 24-month tax exemption for wells using recycled water (proportional to recycled water usage). For orphaned wells, producers must post a $25,000 surety bond per well to qualify for a 50% tax reduction for 36 months. The bill sets annual refund limits of $15 million for recovery projects and $10 million for recycled water exemptions, requiring producers to apply for refunds through the Tax Commission.
SB 37 would have authorized the Oklahoma State Bureau of Investigation (OSBI) to independently respond to mass casualty events caused by violent crime (defined as incidents injuring ≥3 people, requiring unusual emergency resources, and causing a sudden surge of casualties) without needing a local law enforcement request. It created a "Mass Casualty Revolving Fund" in the state treasury to cover OSBI costs for these investigations, funded by state appropriations, federal grants, or other designated sources. The fund would allow ongoing, unrestricted spending for OSBI's role in coordinating with local agencies during such events. This bill was vetoed by the Governor on May 5, 2025, so it did not become law.
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.
HB 1201 creates a 70% tax credit for Oklahoma taxpayers who donate to certified pregnancy resource centers, capping the credit at $50,000 per donor annually. To qualify, centers must provide free, non-abortion services (like prenatal care and counseling) without performing or referring for abortions, and must be certified by the state health director. The total annual tax credits for all donors are capped at $5 million, with annual adjustments to prevent exceeding this limit. The credit applies to donations of $100 or more and takes effect January 1, 2026.
HB 2590 requires Oklahoma's Office of Management and Enterprise Services to create a standardized form for state agencies evaluating vendors managing federal funds. This form must include specific vendor details like legal name, incorporation jurisdiction, principal officers' names, prior federal fund management experience, recent financial audits, and pending lawsuits. It directly affects state agencies contracting with external vendors for federal fund management. The bill mandates this form be used starting July 1, 2025, to standardize vendor vetting processes.
HB 1220 prohibits Oklahoma cities and towns from imposing franchise fees or sales/use taxes on specific revenue streams used by utilities to repay private financing. It directly affects electric cooperatives and other utilities that used private financing under the February 2021 Utility Consumer Protection Acts to avoid immediate cost burdens on customers. The bill defines "securitization revenue streams" as rates and charges solely for repaying such private loans, and bans local taxes on these streams for bonds issued by the Oklahoma Development Finance Authority under those acts. This prevents municipalities from taxing revenue dedicated to repaying utility loans structured to protect consumers from upfront costs.
HB 2745 creates new tax deductions for Oklahoma banks and credit unions that earn interest on qualifying agricultural and housing loans. It allows institutions to deduct up to $500,000 annually (for those with over $750 million in Oklahoma deposits) or $250,000 (for smaller institutions) from their privilege tax bill. The deductions apply to interest earned on agricultural real estate loans, agricultural operating loans, and single-family residence loans made between 2025 and 2028. Total deductions across all institutions are capped at $5 million per year, with annual adjustments to maintain this limit.
HB 1539 lowers Oklahoma's individual income tax rates for the 2024 tax year. It reduces the top tax rate from 5.50% to 4.75% for most filers, with new brackets starting at 0.25% on the first $1,000 of income (e.g., 0.75% on the next $1,500 for single filers). The bill affects all Oklahoma residents and nonresidents who file individual income tax returns, applying to taxable income earned in 2024. The change eliminates the previous tiered top rate structure and requires no deduction for federal income taxes paid.
