Does Oklahoma Tax Social Security and Retirement Income?

Oklahoma does not tax Social Security

Oklahoma law has exempted Social Security benefits from taxable income since 1985, to the extent they are included in federal adjusted gross income. There is no income limit and no age condition, and the exemption is separate from the $10,000 exclusion for other retirement income, so benefits use up none of that room. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

The taxable amount from the federal return is entered on Schedule 511-A, line 2. Railroad Retirement Board benefits included in federal AGI are subtracted the same way on Schedule 511-A, line 7. In our three example households the Social Security subtraction is $25,500, $46,750 and $59,500. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

The federal government is a separate matter. Up to 85% of a benefit can be taxed on a federal return once other income passes fixed thresholds, wherever you live. Our taxable Social Security calculator shows how much of yours is counted.

The first $10,000 of each person’s pension income is excluded; military and CSRS pensions are exempt

A private-employer pension is “other retirement income” on Schedule 511-A, line 6. Each individual may exclude up to $10,000, but not more than the amount included in federal AGI, of benefits from a qualified employer plan under Internal Revenue Code section 401, a 403(a) or 403(b) annuity, a 457 deferred compensation plan or an IRA. The benefits must be in that person’s own name. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

The statute once limited this exclusion to people 65 or older with modest incomes. The age test was dropped for tax years after 2004, the income ceiling was raised in steps, and since the tax year beginning January 1, 2010 there has been no income limit at all. The $10,000 figure has applied since 2006. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

Pensions from Oklahoma’s state, teacher, police, firefighter, county and municipal retirement systems and from the federal civil service get the same $10,000, claimed on line 5. The two lines share one cap: a person who excludes $10,000 of government pension on line 5 has nothing left for an IRA or private pension on line 6. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Federal retirees under the Civil Service Retirement System (CSRS), whose pensions were paid in place of Social Security, exclude 100% of those benefits on line 3, survivor benefits included. Pensions under the newer Federal Employees Retirement System (FERS) do not qualify for that line, except for the CSRS component of a mixed pension and the FERS annuity supplement paid until age 62; the rest of a FERS pension falls under the $10,000 limit. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Retirement benefits from any component of the U.S. Armed Forces have been fully exempt since tax year 2022. From 2006 through 2021 the exemption was the greater of 75% of the benefits or $10,000. Military retirement is subtracted on Schedule 511-A, line 4, and does not count against the $10,000 available for other retirement income. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

IRA and 401(k) withdrawals share the $10,000 exclusion with pensions

The statute defines the retirement benefits that qualify as total distributions or withdrawals from section 401 employer plans, which include 401(k) plans, from IRAs and simplified employee pensions under section 408, from 403(b) annuities and 457 plans, and lump-sum distributions. One $10,000 limit covers a person’s total. The single retiree in our examples, with a $20,000 pension and $20,000 of IRA withdrawals, excludes $10,000 and is taxed on $30,000. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

The limit is applied person by person. In our first couple, one spouse has $55,000 of pension and IRA income and the other $15,000; each excludes $10,000, so $50,000 of the $70,000 stays in Oklahoma income. A spouse with no retirement income of their own adds nothing to the couple’s exclusion. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

The statute has no separate rule for Roth conversions. It mentions them once, to leave conversion income out of the federal AGI test for the extra $1,000 exemption at age 65. Conversion income is part of federal AGI on Form 511, line 1, and whatever is not covered by that person’s $10,000 exclusion is taxed at the ordinary rates, 4.5% for most retirees. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

To size a conversion against federal brackets and Medicare surcharges, see the Roth conversion calculator; for required withdrawals, the RMD calculator.

Interest, dividends and gains are taxed as ordinary income, except gains on Oklahoma property

Oklahoma starts from federal AGI and taxes residents on all non-business interest and dividends wherever they are earned. Interest on U.S. government obligations is subtracted on Schedule 511-A, line 1, but interest from Fannie Mae and Ginnie Mae securities does not qualify. Interest on bonds of other states is added back. Bonds of the State of Oklahoma and several state authorities are exempt, as are local Oklahoma government obligations issued after July 1, 2001. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Long-term gains on a stock or fund portfolio get no lower rate; a $40,000 gain adds $1,800 of tax at 4.5%. The exception is the Oklahoma capital gain deduction. Net capital gain is deductible in full when it comes from real or tangible personal property located in Oklahoma that was owned for at least five uninterrupted years, or from stock or an ownership interest in an Oklahoma company owned for at least two years. A qualifying company must have had its primary headquarters in Oklahoma for at least three years. (Oklahoma Tax Commission, Form 561: Oklahoma Capital Gain Deduction for Residents Filing Form 511 (2025), with instructions)

House Bill 2764 of 2025 replaced the six brackets used for 2024 and 2025, which ran from 0.25% to 4.75%, with the four above for tax year 2026. The first $3,750 of taxable income ($7,500 on a joint return) is now taxed at 0%, and the top rate of 4.5% begins at $7,200 single and $14,400 joint, the same thresholds as before. (Oklahoma Legislature, Enrolled House Bill 2764 (2025): 68 O.S. 2355 rates for tax year 2026 and 62 O.S. 34.103 rate reduction certifications)

The Tax Commission’s summary gives the 2026 tax above the top threshold as $109.25 plus 4.5% of the excess over $7,200 for single filers and $218.50 plus 4.5% of the excess over $14,400 for joint filers. The 2026 Form 511 and its tax table have not been published, so the examples on this page apply this schedule to exact taxable income; the printed table works in $50 bands and can differ by a dollar or two. (Oklahoma Tax Commission, Summary of 2025 Tax Legislation (2026 tax bracket tables))

The Oklahoma standard deduction is fixed in statute at $6,350 for single filers and $12,700 for joint filers and is not indexed. A filer who took the federal standard deduction must take Oklahoma’s, and one who itemized federally must itemize in Oklahoma, where itemized deductions other than charitable gifts and medical expenses are capped at $17,000. Each exemption is worth $1,000. Line numbers here come from the 2025 Form 511 packet, the latest published. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

An additional $1,000 exemption for a filer or spouse who is 65 or older exists only at low incomes: federal AGI of $15,000 or less on a single return or $25,000 or less on a joint return. None of our example households qualifies. Legal blindness adds $1,000 at any income. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Oklahoma’s retirement breaks mostly have no age test: the Social Security exemption, the $10,000 exclusion and the military and CSRS exemptions apply at any age. The one age-based income tax item, the extra $1,000 exemption at 65, is limited to federal AGI of $15,000 single or $25,000 joint, measured without Roth conversion income. (Oklahoma Statutes, Title 68, Section 2358 (adjustments to income: Social Security, retirement benefits, military retirement, exemptions), as set out in Enrolled House Bill 4432 (2026))

The Sales Tax Relief Credit pays $40 for each qualifying exemption: the filer, a spouse and each dependent. It is open to full-year residents with gross household income of $20,000 or less, or $50,000 or less when the filer or spouse is 65 or older, has a dependent or has a qualifying disability. Gross household income counts Social Security and other nontaxable income. The claim is made on Form 538-S and carried to Form 511, line 25. (Oklahoma Tax Commission, Form 538-S: Claim for Credit/Refund of Sales Tax (2025), with instructions)

The same three households appear on every state page, so the figures can be compared across states. Each is a full-year resident taking the standard deduction, with no dependents. The figures are state income tax only: any county, city or school district income tax is described on this page but not added in. Pension income is from a private employer, and IRA figures are taxable withdrawals from traditional accounts. The state tax is our calculation from Oklahoma's published 2026 rules; it is an illustration, not a return.

These households also owe federal income tax, which is the same wherever they live. The tax bracket calculator and the guide to taxes in retirement cover that side.

As a comparative measure, Tax Foundation figures drawn from Census data put Oklahoma property taxes at 0.79% of owner-occupied home value in 2024, 26th highest among the states. Its county figures are 0.92% in Oklahoma County and Cleveland County and 0.98% in Tulsa County, or about $3,700 to $3,900 a year on a $400,000 home. (Tax Foundation, Property Taxes by State and County, 2026 (comparative figures from Census ACS data))

The state constitution limits how fast a home’s taxable value can rise. The fair cash value of homestead property and agricultural land cannot increase by more than 3% in a year, and other locally assessed real property by more than 5%. The cap comes off in a year when title is transferred, so a buyer starts from a fresh valuation, and improvements are added at their value. (Oklahoma Tax Commission, Oklahoma Administrative Code 710:10, Ad Valorem (2026): valuation limitation and senior valuation limitation rules)

The senior valuation freeze goes further. A head of household who is 65 or older on January 1, owns and occupies the homestead, and had gross household income for the previous year at or below the limit for the county can have the home’s fair cash value held at its current level. The limit is the median income the U.S. Department of Housing and Urban Development estimates for the county or metropolitan area. The application is Form 994, due to the county assessor by March 15. (Oklahoma Tax Commission, Form 994: Application for Property Valuation Limitation and Additional Homestead Exemption (revised 11-2026))

In Oklahoma County the limit for 2026 is $99,000 of total household income, up from $89,500, and the assessor says the same $99,000 applies in Canadian, Cleveland, Logan and McClain counties. Owners already under the freeze do not reapply. (Oklahoma County Assessor, Increased Property Tax Savings for 2026 (December 18, 2025))

The freeze is on value, not on the bill. Taxes on a frozen home can still rise when voters approve a bond issue or another levy, or when a court orders an additional levy. Gross household income for the freeze counts every kind of income of everyone in the home, taxable or not, including Social Security, pensions and capital gains. If income goes over the limit, the freeze expires and the value becomes subject to the 3% cap for that year. (Oklahoma Tax Commission, Oklahoma Administrative Code 710:10, Ad Valorem (2026): valuation limitation and senior valuation limitation rules)

Sales tax is where Oklahoma is expensive. As a comparative figure, the Tax Foundation puts the state rate at 4.5%, the average local rate at 4.56% and the combined rate at 9.06% as of January 1, 2026, the sixth highest in the country. Cities and counties both levy sales tax, and local rates reach 7%. (Tax Foundation, State and Local Sales Tax Rates, 2026 (comparative figures))

Since August 29, 2024 the state rate on food and food ingredients has been 0%. The exemption covers only the state portion: all city and county sales taxes still apply to groceries. Prepared food, alcoholic beverages and dietary supplements remain subject to the full 4.5% state rate, and the Tax Commission’s examples of items still taxed include rotisserie chicken, vitamins, pet food, toiletries and over-the-counter medications. (Oklahoma Tax Commission: State Sales Tax on Food and Food Ingredients)

Drugs prescribed for the treatment of people by a licensed prescriber are exempt from sales tax, as are insulin, medical oxygen and prosthetic devices for an individual’s use. Over-the-counter drugs are taxable. (Oklahoma Tax Commission, Oklahoma Administrative Code 710:65, Sales and Use Tax (2026): 710:65-13-170, Drugs and prosthetic devices)

Oklahoma has no estate tax and no inheritance tax. The Oklahoma estate tax was repealed for deaths on or after January 1, 2010, and the Tax Commission’s annual report of every tax it collects shows estate tax collections of $0.00 and lists no inheritance or gift tax. Nothing is owed to the state on an estate of any size, whoever inherits. (Oklahoma Tax Commission, Revenue and Apportionment Report for the fiscal year ended June 30, 2024 (estate tax repealed for deaths on or after January 1, 2010))

The federal estate tax applies in every state. The estate tax calculator estimates both the federal tax and any state tax.

The 2026 rate cut is the first step of a longer design. Under House Bill 2764, each time total state tax collections for a year exceed the highest earlier year by more than a threshold tied to the cost of a cut, every bracket’s rate falls by 0.25 percentage points, and the process repeats until the rates reach zero. A cut does not occur in a year when a revenue failure is declared. (Oklahoma Legislature, Enrolled House Bill 2764 (2025): 68 O.S. 2355 rates for tax year 2026 and 62 O.S. 34.103 rate reduction certifications)

The State Board of Equalization makes its first preliminary finding at its December 2026 meeting and a final certification each February, and a reduction takes effect on the January 1 after that final certification. The earliest a rate below 4.5% could apply is therefore January 1, 2028. For the first test the Board must also certify that revenue in the first five and a half months of the fiscal year ending June 30, 2027 came within 95% of the February 2026 estimate. (Oklahoma Legislature, Enrolled House Bill 2764 (2025): 68 O.S. 2355 rates for tax year 2026 and 62 O.S. 34.103 rate reduction certifications)

State Question 847, referred to voters by the 2026 Legislature as Senate Joint Resolution 39, would have lowered the annual cap on a homestead’s taxable value from 3% to 1.75% from tax year 2027, lowered the cap on other real property from 5% to 4%, and added a further graduated limit for some senior homesteads based on county median income. (Oklahoma Tax Commission, 2026 Tax Legislation Summary)

Voters rejected it at the general election on November 3, 2026, by 585,734 votes (54.27%) to 493,467, in the State Election Board’s official results. The 3% and 5% caps and the existing senior valuation freeze continue unchanged. (Oklahoma State Election Board, Official Results: November 3, 2026 General Election)

An Oklahoma resident is a person domiciled in the state for the entire tax year, and domicile is the true, fixed and permanent home, the place a person intends to return to when away. Once established it continues until a new one is adopted. Someone domiciled in Oklahoma for less than 12 months of the year is a part-year resident. The test is domicile; the instructions set no day count. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Part-year residents and nonresidents file Form 511-NR. Tax is first computed as if all income were earned in Oklahoma and is then prorated by Oklahoma-source adjusted gross income over adjusted gross income from all sources. A part-year resident reports as Oklahoma income the pensions, annuities and Social Security received while a resident and none of what was received as a nonresident. (Oklahoma Tax Commission, 2025 Oklahoma Nonresident and Part-Year Resident Income Tax Forms and Instructions (Form 511-NR packet))

Residents are not taxed on rents, business income or real estate gains from property in another state, though a return with such income must prorate its deductions and exemptions on Schedule 511-E. Wages, pensions, interest and dividends are taxed in full wherever they arise. (Oklahoma Tax Commission, 2025 Oklahoma Resident Individual Income Tax Forms and Instructions (Form 511 packet, including Schedule 511-A))

Under federal law (4 U.S.C. 114) a state cannot tax the retirement income of a person who is not its resident or domiciliary. A pension or 401(k) earned in Oklahoma is taxed only by the state where the retiree lives when it is paid, and a pension earned elsewhere qualifies for the Oklahoma exclusion once the retiree is domiciled there. (4 U.S.C. 114, Limitation on State income taxation of certain pension income)
