OK HB4231

Increases the retirement benefit computation factor for Oklahoma firefighters from 2.5% to 3% per year of credited service, with phased eligibility: members with 25+ years can receive the increase 1 year after the effective date, those with 20+ years after 2 years, and all members after 5 years

Applies the same 3% multiplier increase to disability retirement benefits for firefighters who become disabled in the line of duty and have 20+ years of credited service

Establishes a minimum municipal contribution of 14% of actual paid base salary for each firefighter employed by the municipality

Amends the Oklahoma Pension Legislation Actuarial Analysis Act to classify these benefit computation changes as "nonfiscal," meaning they do not require actuarial analysis before passage

Contains emergency clause provisions with contingent effective dates: if the emergency clause is approved, takes effect immediately upon signature; otherwise, October 1, 2026 for definitional changes and November 1, 2026 for benefit changes
