HB 2087 Oklahoma House · 2026 Regular Session

Revenue and taxation; income tax credit; research institutes; effective date.

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.

MODERATE

The bill was amended to transition from a House floor version to a Senate floor version, incorporating committee amendments that modify tax credit limits, eligibility rules, and funding caps for donations to biomedical and cancer research institutes. The changes adjust credit percentages based on usage, introduce new taxpayer filing category distinctions, and establish stricter annual caps on total credits available for each type of institute.

Scope change

The bill's scope remains focused on income tax credits for research institute donations, but applicability rules were modified to include specific taxpayer filing categories and business entity definitions.

FISCAL

Adjusted annual credit limits for independent biomedical research institutes from $2,000,000 to $1,500,000 for tax years 2026 and beyond, and set a $500,000 cap for cancer research institutes in the same period.

ELIGIBILITY

Added specific credit limits based on taxpayer filing status (single, married filing jointly, head of household, etc.) and business entity types for tax years 2026 and beyond.

REQUIREMENT

Modified the formula for calculating credit percentages to use the second preceding year's credit claims instead of the preceding year's claims for tax years 2026 and later.

Added a requirement that taxpayers cannot claim more than one credit per donation type per taxable year, with specific dollar limits per filing category.

TIMELINE

Extended certain credit limit provisions to apply to tax years 2026 and subsequent years, with different thresholds than previous years.
