New limits for research donation credits
The law takes effect November 1, 2025, with new Oklahoma research donation credit limits starting in tax year 2026. Credits cover up to 50% of qualifying donations. For each research category, single filers and married people filing separately have a $1,000 credit limit. Joint filers, heads of household, and qualifying surviving spouses have a $2,000 limit per category. Businesses, including partnerships, corporations, and LLCs, have a $25,000 annual limit per category. Through 2025, the two categories share a $2 million annual cap, with rate formulas using $1 million for each category. Starting in 2026, the annual caps are $1.5 million for biomedical donations and $500,000 for cancer research donations. Each category's rate equals 50% times its cap divided by credits claimed two tax years earlier, never exceeding 50%. The earlier formulas use credits claimed one year earlier. Taxpayers can claim only one credit per institute type each year. Credits cannot exceed the taxpayer's Oklahoma income tax bill; unused credits carry forward for four years after qualification. The Oklahoma Tax Commission can prescribe claim forms.
Stricter eligibility for research donation credits
Beginning November 1, 2025, qualifying biomedical institutes need $20 million in yearly National Institutes of Health funding, up from $15 million. Donations to institutes below that threshold do not qualify for the Oklahoma tax credit. Biomedical institutes must be Oklahoma-based, tax-exempt nonprofits focused on peer-reviewed basic biomedical research. They must have their own board and staff and accept grants in their own name. Cancer research recipients must be tax-exempt nonprofits focused on improving Oklahoma cancer care through peer-reviewed research and education, or nonprofit supporting organizations. They must be affiliated with a tax-exempt organization focused on Oklahoma cancer care and receive at least $4 million yearly from the National Cancer Institute. Cancer recipients can be independent institutes or programs within universities in Oklahoma's state higher education system.
