Revenue and taxation; Health Care Sharing Ministry Tax Parity Act; definitions; income tax deduction; effective date.

HB 1473, the "Health Care Sharing Ministry Tax Parity Act," allows Oklahoma residents who are active members of qualifying health care sharing ministries (HCSMs) to deduct their membership contributions from their state income taxes starting in 2026. It treats these deductions similarly to health insurance premiums, applying to self-employed individuals, employer contributions (as nontaxable benefits), and individuals covering themselves or dependents. To claim the deduction, members must provide documentation of contributions and membership, and false claims could result in $500 penalties per offense and three years of ineligibility. Funds received from HCSMs for medical expenses will not be considered taxable income under Oklahoma law.
