How does Oklahoma state income tax and unemployment insurance work in 2026?
Oklahoma has a graduated income tax topping out at 4.5% in 2026, withheld via OTC tables. On top sit unemployment insurance on a $25,000 wage base at a 1.50% new-employer rate, plus the federal stack.

Oklahoma is the state where the headline got smaller for 2026. House Bill 2764 cut the top income tax rate from 4.75 percent to 4.5% and folded six brackets into three, so you still withhold state tax, just a little less of it. There is a real OK-W-4 equivalent and a real bracket table published by the Oklahoma Tax Commission.
The rest of the employer cost sits in two boxes. Unemployment insurance runs on a $25,000 wage base at a 1.50% new-employer rate, a base that actually fell for 2026. On top sits the federal stack: Social Security, Medicare and FUTA, the same in every state. Compare how Oklahoma stacks up against neighbouring Texas state tax and UI and Kansas state tax and UI.
Does Oklahoma have a state income tax in 2026, and what are the brackets?
Yes. Oklahoma has a graduated state income tax, and for 2026 it runs across three brackets topping out at 4.5% on taxable income over $7,200 for single filers. The first $3,750 of taxable income is taxed at 0%.
House Bill 2764 reshaped this from 1 January 2026. It cut the top rate from 4.75 percent to 4.5% and consolidated six brackets into three, so you withhold less, but you still withhold.
For a single filer in 2026, the schedule runs in steps: 0% on the first $3,750 of taxable income, 2.50% on income from $3,750 to $4,900, 3.50% from $4,900 to $7,200, and 4.50% on everything above $7,200. Because the thresholds are low, most full-time wages reach the top rate quickly, so 4.5% is the marginal rate that matters for payroll. If you're hiring across borders and need to model the full employer of record cost, the Employer Cost Calculator runs the numbers against current Oklahoma rates.
The standard deduction is $6,350 for a single filer, with a $1,000 personal exemption per allowance. HB 2764 changed the brackets and rates, not the standard deduction, so the deduction holds at its prior level for 2026. The Act also carries a trigger: a further 0.25 percent cut across all brackets can fire when state revenue clears a benchmark, which is how Oklahoma has signalled a path toward eliminating the tax over time. By contrast, Texas levies no state income tax at all, which changes the withholding picture entirely.
How does Oklahoma income tax withholding work for employers?
You withhold Oklahoma income tax from every paycheck using the Oklahoma Tax Commission's 2026 tables, after subtracting withholding allowances worth $1,000 each per year. The employee sets allowances on Form OK-W-4.
There is no flat withholding rate. You apply the same graduated schedule that tops out at 4.5%, then remit to the OTC on a schedule tied to how much you withhold.
The mechanics are familiar if you run any graduated-tax state. Each employee files Form OK-W-4, you reduce taxable wages by their allowances, and you read the Oklahoma Tax Commission percentage formula or wage-bracket tables to find the amount to withhold. The 2026 tables already bake in the 4.5% top rate and the three-bracket structure, so a payroll system loaded with current tables withholds the right amount without manual maths. If you want to compare the withholding obligation against a state with different bracket mechanics, see how we cover Kansas state income tax.
Remittance frequency follows your withholding volume, and you reconcile annually. Married employees are taxed on combined income in Oklahoma, which is why the OTC offers a 'withhold at higher single rate' election on the OK-W-4 for dual-income couples who would otherwise under-withhold. Register for withholding with the Oklahoma Tax Commission before your first payroll, because the state account number gates your filings. Before you register and before you hire, check Oklahoma's wage and overtime rules, because the payroll clock starts on day one.
What is Oklahoma's unemployment insurance wage base and rate for 2026?
Oklahoma's UI taxable wage base is $25,000 per employee for 2026, down from $28,200 in 2025. New employers pay a UI rate of 1.50% on that base.
Experience-rated employers fall on a rate set by their own claims history, from a 2026 minimum of 0.20% to a maximum of 5.80%. At 1.50% on a $25,000 base, a new employer pays at most about $375 per employee a year.
Hire your first Oklahoma employee and you pay UI on the first $25,000 of their wages at a new-employer rate of 1.50%. Experience-rated employers pay between 0.20% and 5.80%, filed and paid quarterly to the Oklahoma Employment Security Commission.

The $25,000 base actually dropped for 2026, one of only a handful of states to move down, which trims your per-employee UI cost year on year. You pay UI on the first $25,000 of each employee's wages; everything above that in the calendar year is not taxed. To see how the wage base sits relative to a neighbouring state, compare Arkansas state tax and UI.
A new employer holds the 1.50% entry rate until it has enough claims history to be experience-rated, then moves onto a rate built from its own record within the 0.20% to 5.80% band. The federal layer sits on top: FUTA is 6.0 percent on the first $7,000 of wages, less the full credit for compliant state payers, leaving an effective 0.6%. Oklahoma's consistent UI filings qualify you for the full FUTA credit.
What other payroll rules apply to Oklahoma employees?
You run the full federal stack: Social Security at 6.2% to $184,500, Medicare at 1.45%, and FUTA at an effective 0.6%. Oklahoma's minimum wage is the federal $7.25 an hour, with a $2.13 tipped cash minimum.
Oklahoma mandates no state paid leave. There is no state paid-family-leave programme and no state paid sick leave, so federal FMLA at 50 employees is the only job-protected family leave layer.
Two points catch out-of-state employers. First, the minimum wage: Oklahoma adopts the federal $7.25 by reference and has held there since 2009, with tipped staff payable at a $2.13 cash wage as long as tips bring them to $7.25. State Question 832 on the June 2026 ballot would raise that floor in stages, but until voters pass it the rate stays at $7.25. Oklahoma's wage and overtime rules cover overtime, break obligations, and the tipped-wage mechanics in full. Second, leave: Oklahoma has no state mandate, so any paid time off you offer is a benefit you choose, not a statute you follow. The full picture of what Oklahoma employees can and cannot claim is in the Oklahoma paid family and sick leave guide.
That makes federal FMLA the whole of the job-protected family-leave picture: up to 12 weeks of unpaid, job-protected leave for employers with 50 or more staff within 75 miles. Social Security runs at 6.2 percent each side to $184,500, Medicare at 1.45 percent on all wages, and a 0.9 percent additional Medicare applies to employee wages over $200,000.

How Teamed runs Oklahoma payroll end to end
Teamed becomes your legal employer of record in Oklahoma for $599 per employee per month flat. Zero FX mark-up. Statutory employer cost passes through at cost, itemised on every invoice.
You hire the person. Teamed registers with the Oklahoma Tax Commission and OESC, withholds and remits state income tax against the 2026 tables, files and pays unemployment insurance each quarter, and runs the full federal stack. Everything runs on one platform.
Real HR and legal experts handle your Oklahoma hires and know the three-bracket 4.5% withholding schedule, the $25,000 UI wage base, and the 1.50% entry rate. An actual person, not a chatbot or a pooled queue. You see every cost: state income tax withholding, unemployment insurance, and federal employer taxes pass through at cost, itemised and auditable on every invoice. No setup fee, no exit fee.
Contractor onboarding, EOR payroll, and entity graduation all live on one platform: an Oklahoma contractor who converts to W-2 keeps their record, and that same employee can graduate to your own US entity without switching systems. Because Oklahoma's rates are falling and its UI base is low, the running cost of an Oklahoma hire is moderate, so the case for your own entity arrives later per headcount than in a high-tax state. Use the Crossover Calculator to see the month the model flips, and the Employer Cost Calculator to price the full stack today. EOR is the right model for Oklahoma, until it isn't. If you need to understand how termination works before you commit to a hire, the Oklahoma termination guide covers at-will exceptions and final-pay rules.
The mistake we see on Oklahoma is treating the 2026 rate cut as a reason to stop paying attention. The top rate fell to 4.5 percent and the brackets consolidated, but you still withhold on every paycheck, still file with the OTC, and still run unemployment insurance on a base that changed this year. Lower is not nothing. Budget for the boxes that still carry cost.
