Payroll Oklahoma: Employer Tax and Software Guide

Oklahoma is one of the simpler states to run payroll in, and this year it got simpler still in a way that quietly broke a lot of reference material.

Six income tax brackets collapsed into three effective January 1, with the top rate falling from 4.75 to 4.5 percent. The unemployment wage base moved in the direction wage bases almost never move: down, from $28,200 to $25,000. And the legislation that restructured the brackets built in a mechanism that could reduce the income tax to zero over time in quarter-point steps.

The result is that a good deal of Oklahoma payroll guidance currently in circulation is describing a system that no longer exists. Rates of 0.25 and 2.75 percent, a married filing jointly threshold of $12,200, a wage base of $28,200: all correct until recently, all wrong now. This guide covers what Oklahoma requires today, what changed for 2026, and how 10 payroll providers price the work.

What Oklahoma requires from employers

The obligation set here is short, which is worth stating plainly before going into the parts that changed.

Two agencies rather than one, and registration is separate for each: state withholding through the Tax Commission, unemployment through the Employment Security Commission. Employer withholding is remitted on Forms WTH-10001 and WTH-10004, and employees complete Form OK-W-4 for state withholding alongside the federal W-4.

One small scheduling difference is worth noting: the Oklahoma individual income tax filing deadline is April 20, five days after the federal date. That does not affect payroll processing, but it affects the questions employees ask in April.

The bracket restructure and the phase-out trigger

House Bill 2764, signed by Governor Stitt in May 2025, is the most consequential change to Oklahoma payroll in years.

The withholding tables in Packet OW-2, revised November 2025 and effective January 1, 2026, implement these rates through percentage-of-excess formulas by payroll period, with an annual personal allowance of $1,000 divided across the number of pay periods.

The trigger that could zero the tax

House Bill 2764 also created a forward-looking mechanism that could phase the personal income tax out entirely. Each winter the State Board of Equalization compares total tax collections from a comparison year against a base year. Where collections exceed the base by at least 1.25 times the cost of a quarter-point rate cut, the reduction takes effect automatically. If a revenue failure is declared, any pending reduction is cancelled.

For an employer the operational consequence is a maintenance question rather than a compliance one: Oklahoma withholding tables may now change on a schedule driven by revenue certification rather than by legislative session, so the January table check matters more here than in states with static rates.

An unemployment wage base that went down

State unemployment wage bases almost always rise, because most states index them to average wages that climb every year. Oklahoma's fell for 2026, and the reason is structural rather than accidental.

Oklahoma derives its wage base from average annual wages and sets rate schedules by a conditional factor reflecting trust fund health. The state moved from Conditional Factor D to Conditional Factor A, its healthiest rating, which simultaneously lowered the employer wage base and raised the maximum weekly benefit by roughly 20 percent. Employers pay less; claimants receive more; both follow from the same fund condition.

Quarterly contribution reports are filed on Form OES-3 through the Employment Security Commission portal. Our guide to state unemployment tax covers how experience rating works generally.

Wage rules and new hire reporting

Minimum wage after State Question 832

Oklahoma's minimum wage is $7.25, matching the federal floor. State Question 832, a ballot measure that would have raised it to $15 by 2029, was rejected in June 2026 with more than 56 percent of voters opposed. No increase is scheduled, and cities are preempted from setting their own rates, so there is no municipal variation anywhere in the state.

Overtime follows the federal Fair Labor Standards Act with no state addition, which our guide to overtime pay covers, and the tipped wage and tip credit follow federal rules, covered in our guide to the minimum wage for tipped employees.

New hire reporting

New hires are reported to the Employment Security Commission within twenty days of hire under 40 O.S. Section 2-802, using Form OES-112 or the online system. Employers reporting electronically may instead file twice monthly, with submissions between twelve and sixteen days apart. Our guide to new hire reporting covers what each report must contain.

Workers compensation

Oklahoma operates a competitive workers compensation market: employers buy coverage from private carriers or qualify to self-insure. This distinguishes it from the four monopolistic states where coverage must come from a state fund, and it means a payroll provider that bundles workers compensation can genuinely place a policy here. Our guide to workers compensation insurance covers how state systems differ.

10 payroll providers for Oklahoma employers compared

Every provider below files Oklahoma state withholding and unemployment contributions. Because there is no local tax layer and no disability or paid leave program, the main differentiator this year is narrower than usual: whether the platform applied the new bracket structure when it took effect in January.

OnPay

One plan at $49 per month plus $6 per employee, everything included, no tiers to climb. Tax filing covers all 50 states with no multi-state surcharge, and year-end W-2 and 1099 filing sits in the base price. OnPay maintains an Oklahoma-specific tax rates resource, a reasonable proxy for whether a vendor keeps state tables current in a year when the entire bracket structure changed.

Gusto

The most common first payroll purchase for US small businesses, with automatic tax filing, published pricing, and the strongest onboarding experience among payroll-first platforms. Simple runs $49 per month plus $6 per employee after a base increase in early 2026, and Gusto documents Oklahoma registration with both the Tax Commission and the Employment Security Commission including third-party agent setup.

The constraint is the single-state limit on Simple. Oklahoma borders six states, so one cross-border hire moves you to Plus at $80 plus $12 per employee.

Patriot Software

The cheapest legitimate full-service payroll on the market. Full Service is $37 per month plus $5 per employee and includes federal and state tax filing plus new hire reporting. Basic is $17 plus $4 if you file taxes yourself, which in Oklahoma means handling the quarterly OES-3 and the withholding remittances by hand.

Square Payroll

At $35 per month plus $6 per person, Square is the cheapest full-service option with published pricing, and the full-service plan covers state tax filing and new hire reports. For an Oklahoma City or Tulsa restaurant already running Square point of sale, timecard data flows straight into payroll with no integration work.

SurePayroll

Owned by Paychex and built for very small employers and household employers. Full Service is $29 per month plus $7 per employee, with a flat $9.99 monthly multi-state fee rather than a per-state charge, which suits an Oklahoma employer with staff over one of its six borders.

QuickBooks Workforce Payroll

Core is $50 per month plus $6.50 per employee, and the argument for it is unchanged: if your books live in QuickBooks Online, payroll reaches the general ledger without an export.

ADP RUN

ADP has the deepest tax compliance engine in the category, and it maintains a physical presence in Oklahoma City. In a year when the bracket structure changed entirely, the practical value of that depth is that statutory changes reach the tax tables without customer intervention.

The cost is opacity. ADP does not publish RUN pricing; third-party estimates put Essential near $79 per month plus $4 per employee, but every quote is individual. Contracts typically run a year with automatic renewal and a 30 to 60 day cancellation window.

Paychex Flex

Paychex competes on service rather than software, and unusually among quote-driven vendors it publishes an entry rate: Essentials at $39 per month plus $5 per employee, with higher tiers quoted individually. It maintains an Oklahoma locations presence covering Oklahoma City, Tulsa, and smaller markets.

Paycor

Paycor sits between small-business payroll and full HCM, aimed at companies that have outgrown basic payroll, and maintains an Oklahoma locations presence. The platform bundles payroll with onboarding, performance, and learning modules. Pricing is quote-based and implementation is a project rather than a signup.

Rippling

Rippling unifies payroll, HR, and IT provisioning on one employee record. The core platform is $35 per month plus $8 per employee, with payroll as a separate module. Real-world all-in costs land between $25 and $45 per employee per month once you assemble a working configuration.

What each provider actually costs an Oklahoma employer

The table below models published rates at three headcounts. Oklahoma is one of the states where these figures approximate the whole software cost, since there is no disability carrier, no paid leave remittance, and no local filings.

Square is the cheapest published option at every headcount, with Patriot and Paychex Essentials close behind. Gusto Simple is competitive until one cross-border hire forces the Plus tier, taking a 25-person payroll from $199 to $380 per month, and Oklahoma borders six states so that scenario is not remote.

Choosing a payroll provider for Oklahoma

Before you choose

FirstHR does not process payroll, file payroll taxes, or administer benefits. Every provider above does something we do not, and if running payroll is the problem in front of you, one of them is the answer.

What we handle is the document layer that feeds payroll: onboarding workflows, e-signature on Form OK-W-4, I-9s, and offer letters, employee records, and document management for 5 to 50 employee US teams at a flat $98 to $198 per month. Two of the Oklahoma requirements above are document problems rather than payroll problems, namely getting OK-W-4 signed alongside the federal W-4 before day one, and filing the new hire report within twenty days of the hire date. Our Oklahoma HR compliance guide covers the wider set of state obligations beyond payroll.

Frequently Asked Questions

What are the Oklahoma payroll taxes an employer has to handle?

Two at state level plus federal: income tax withholding on three taxable brackets topping out at 4.5 percent, and unemployment insurance on the first $25,000 of wages at 1.5 percent for new employers. There is no local income tax, no state disability program, and no paid family leave contribution. See our overview of payroll taxes by state for how this compares elsewhere.

What are the Oklahoma income tax rates?

Three taxable rates of 2.5, 3.5, and 4.5 percent plus a zero band, under House Bill 2764 signed in May 2025 and effective for tax year 2026. The top rate fell from 4.75 percent. Withholding tables in Packet OW-2, revised November 2025, implement the change. Rates of 0.25 or 2.75 percent belong to the retired six-bracket schedule.

Where do the Oklahoma tax brackets start?

For single filers and married filing separately: zero up to $3,750, 2.5 percent to $4,900, 3.5 percent to $7,200, and 4.5 percent above $7,200. For joint filers, head of household, and surviving spouse the thresholds double: zero to $7,500, 2.5 percent to $9,800, 3.5 percent to $14,400, and 4.5 percent above $14,400. A joint threshold of $12,200 is the pre-2026 figure.

Could Oklahoma eliminate its income tax?

House Bill 2764 built in a trigger that cuts rates by 0.25 percentage points whenever the State Board of Equalization certifies that collections exceed a base year by at least 1.25 times the cost of the cut, with the phase-out running to zero over time. A declared revenue failure cancels any pending reduction, so the path is conditional rather than scheduled.

What is the Oklahoma unemployment insurance wage base?

$25,000 per employee for 2026, down from $28,200. Contribution rates run from 0.2 to 5.8 percent under Conditional Factor A and new employers pay 1.5 percent. The maximum weekly benefit rose to $649 from $541 under the same change in trust fund condition. Our guide to state unemployment tax covers experience rating.

How long do new Oklahoma employers hold the 1.5 percent rate?

Until they build at least four quarters of experience within a rate cycle. An established employer filing four consecutive no-wage reports reverts to the new employer rate the following calendar year. Rate protests use Form OES-048P within 20 days of the notice date and can only challenge benefit wage ratio calculations or timely taxable wage figures.

What is the minimum wage in Oklahoma?

$7.25, matching the federal rate. State Question 832, which would have raised it to $15 by 2029, was rejected in June 2026 with more than 56 percent opposed. No increase is scheduled and cities are preempted from setting their own rates, so there is no municipal variation.

How long do Oklahoma employers have to report a new hire?

Twenty days from the hire date, filed with the Employment Security Commission under 40 O.S. Section 2-802 using Form OES-112 or online. Electronic filers may instead report twice monthly with submissions twelve to sixteen days apart. See our guide to tax forms for new employees for the full first-day document set.

Does Oklahoma have local payroll taxes or a state disability program?

No to both. No city or county levies a local income tax, so there is no address-level tax resolution problem. There is no state disability insurance and no paid family leave contribution. Workers compensation runs on a competitive private market rather than a state monopoly.
