2026 edition · statute-cited · part of Clear Money Guide’s 51-state retirement tax series. This guide covers state taxes on retirement income and estate transfers; property and sales taxes vary by county and are outside its scope.
Updated July 24, 2026. Quick answer: Oklahoma’s top rate falls to 4.5% for tax year 2026 under HB 2764 (signed May 28, 2025), which also consolidated the bracket structure and wired in automatic quarter-point cuts — triggered by revenue growth — pointing the rate toward zero over time. Social Security is fully exempt, military retirement is 100% exempt (TY2022+), and other retirement income — government pensions and private qualified plans including 401(k)/IRA distributions — gets a $10,000-per-person exclusion before the graduated rates apply. The estate tax was repealed in 2010; there is no inheritance tax.
The HB 2764 correction (4.5%, and falling on autopilot)
Guides quoting Oklahoma’s top rate at 4.75% are a year behind: HB 2764 cut it to 4.5% starting TY2026 and consolidated the old six-bracket clutter. The law’s distinctive feature is its trigger: further 0.25-point cuts fire automatically when revenue benchmarks are met, meaning Oklahoma’s rate is scheduled to ratchet down without further votes. Combined with the $10,000 exclusion and exempt Social Security, a typical retiree couple’s effective Oklahoma rate lands well under 2% — while stale content keeps them comparing against figures from two rate regimes ago.
How Oklahoma taxes retirement income (statute-cited)
| Income tax | Graduated, top rate 4.5% for TY2026 (HB 2764; automatic 0.25-point trigger cuts toward zero) |
| Social Security | Not taxed (fully exempt to the federally taxable extent) |
| Pension / 401(k) / IRA | $10,000/person exclusion for qualifying retirement income (government pensions and private qualified plans); taxable above |
| Military retirement | 100% exempt (TY2022+; previously the greater of 75% or $10,000) |
| Estate / inheritance tax | None — estate tax repealed 2010 |
Probate: a statutory commission and a $50,000 affidavit
Personal-representative commissions are statutory (58 O.S. §527): 5% of the first $1,000; 4% of the next $5,000; 2.5% of everything above $6,000 of the estate accounted for, plus extraordinary-service allowances; attorney fees are court-allowed and reasonable. Small estates: up to $50,000 passes by affidavit (58 O.S. §393, 10-day wait, no PR appointed), and summary administration is available for estates up to $200,000. Context: probate cost by state · small-estate limits by state.
Is Oklahoma a good state to retire in for taxes?
Quietly competitive and improving by statute: exempt Social Security, full military exemption, a $10,000-per-person cushion, a 4.5% top rate that cuts itself, and no death taxes. Against Texas next door, the practical gap for a modest-income retiree is small and shrinking — and Oklahoma’s 2.5% PR commission on probate estates argues, as everywhere with a schedule, for beneficiary designations on the big accounts. Watch the triggers: if revenue cooperates, this page’s rate table will keep revising downward.

What probate costs in Oklahoma
Oklahoma uses a hybrid standard — a statutory ceiling or floor with reasonableness applied inside it — so the fee has a bound but not a fixed number. Whether its small-estate route of $50,000 reaches real property is not clearly stated in the statute, so treat that as unresolved rather than permission.
