Payroll Oklahoma: Employer Tax and Software Guide

If another founder asked me about running payroll in Oklahoma, I would call it one of the simpler states, then warn that for tax year 2026 it got simpler still in a way that quietly broke a lot of reference material. This guide covers what Oklahoma requires today, what changed for 2026, and how 10 payroll providers price the work.

Six income tax brackets gave way to three taxable rates over a 0 percent band on January 1, 2026, with the top rate falling from 4.75 to 4.5 percent. The unemployment wage base keeps moving in the direction wage bases almost never move: down, to $24,400 from January 1, 2027 ($25,000 through 2026, after $28,200 in 2025).

The result is that a good deal of Oklahoma payroll guidance in circulation describes a system that no longer exists. Rates of 0.25 and 2.75 percent and a wage base of $28,200 were right for 2025 and are wrong now, and a married filing jointly threshold of $12,200 has been out of date since tax year 2024.

The legislation that restructured the brackets also built in a mechanism that could reduce the income tax to zero over time in quarter-point steps, so the tables can change again without a new law.

What Oklahoma requires from employers

The list is short. Oklahoma employers withhold state income tax, pay unemployment insurance, report new hires, and carry workers compensation coverage, and the state adds no local income tax and no disability or paid leave program.

Oklahoma splits the work between two agencies, and you register separately with each: state withholding through the Tax Commission, unemployment through the Employment Security Commission. Employer withholding is reported on Form WTH-10001, the quarterly wage withholding return, together with any payment due. Each employee completes Form OK-W-4 for state withholding alongside the federal W-4.

One small scheduling difference shows up every spring: Oklahoma individual returns are due April 15, like federal returns, but the Tax Commission's filing instructions extend that to April 20 for a return filed electronically. It changes nothing in payroll processing, but it shapes the questions employees bring you 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. It replaced six brackets with three taxable rates over a zero band, and the table below shows where each rate starts.

The withholding tables in Packet OW-2, revised November 2025 and effective January 1, 2026, implement these rates by payroll period through percentage-of-excess formulas: a set dollar amount plus a percentage of the wages above the start of each band. The formulas also account for 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, starting in December 2026, the State Board of Equalization compares total tax collections from a comparison year against a base year.

If comparison year collections beat base year collections by more than a set threshold, every rate drops by 0.25 of a point the following January 1. The threshold is 1.25 times the projected annual cost of a quarter-point cut.

The bill also includes a safeguard: if a revenue failure is declared, meaning state collections fall too far below the official revenue estimate, the pending reduction waits for a later certification.

For you as an employer, this is a maintenance question rather than a compliance one. Oklahoma withholding tables may now change because of a revenue certification rather than a vote in the legislature, 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 rarely fall: most either sit at a fixed figure or, where a state indexes them to average wages, climb with pay. Oklahoma's fell for 2026 and falls again on January 1, 2027, and the reason is structural rather than accidental.

Oklahoma sets its wage base as a percentage of the state's average annual wage, and it picks the rate schedule by a conditional factor, a rating of the unemployment trust fund's health. The percentage shrinks as the fund's condition improves, which is why a healthier fund means a lower base.

The state moved from Conditional Factor D in 2025 to Conditional Factor A, the mildest of its four conditional factors, for 2026. The Employment Security Commission's 2027 figures carry no conditional factor at all.

Each move toward a healthier fund lowered the employer wage base and raised the maximum weekly benefit, which climbed about 20 percent for 2026 alone. Employers pay less and claimants receive more, and both follow from the same fund condition.

Whatever rate you are assigned, quarterly contribution reports are filed on Form OES-3 through the Employment Security Commission portal.

Wage rules and new hire reporting

On pay rates, Oklahoma follows federal law for the minimum wage, overtime, and the tipped wage. The state-specific work is new hire reporting and workers compensation coverage.

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 by voters on June 16, 2026. No increase is scheduled. State law also preempts cities, barring them 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, and the tipped wage and tip credit follow federal rules.

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.

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.

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 here is narrower than usual: whether the platform applied the new bracket structure when it took effect in January 2026.

OnPay

OnPay sells one payroll plan at $49 per month plus $6 per employee, with no tiers to climb; HR tools and time tracking are paid add-ons. 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 also 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

Gusto is a common first payroll purchase for US small businesses, with automatic tax filing, published pricing, and onboarding built into the same account. Simple runs $49 per month plus $6 per employee after a base increase from $40 during 2025.

Gusto also documents Oklahoma registration with both the Tax Commission and the Employment Security Commission, including third-party agent setup, the step that authorizes Gusto to file on your behalf.

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

Patriot Full Service is the lowest-cost full-service payroll on this page at every headcount modeled below, at $37 per month plus $5 per employee. It includes federal, state, and local tax filing, though new hire reports stay with you.

Patriot's Basic plan 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

Square Payroll's full-service plan costs $35 per month plus $6 per person paid and 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

SurePayroll is owned by Paychex and built for very small employers and household employers. Its Small Business plan 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 across any of its six borders.

QuickBooks Workforce Payroll

Workforce Payroll, formerly QuickBooks Payroll Core and renamed in May 2026, runs $50 per month plus $7 per employee after the per-employee increase of July 1, 2026. The argument for it is unchanged: if your books live in QuickBooks Online, payroll reaches the general ledger without an export.

ADP RUN

ADP runs the same tax compliance engine behind every RUN package: it calculates, files, deposits, and reconciles payroll taxes, responds to agency inquiries, and pays the resulting fines if it makes a filing error. When a state rebuilds its whole bracket structure, as Oklahoma did, that depth means statutory changes reach the tax tables without customer intervention.

The cost is opacity. ADP publishes no RUN pricing, so every package from Essential to HR Pro is quoted individually. No contract is required, though: ADP says services can be terminated at any time. It also lists an office in Oklahoma City.

Paychex Flex

Paychex competes on service rather than software, with a payroll specialist included on the Complete package. Pricing is quote-only across the Basic, Foundations, Advanced, and Complete packages, and the standard service agreement can be ended on 30 days' notice.

Paycor

Paycor sits between small-business payroll and a full human capital management suite, aimed at companies that have outgrown basic payroll. It has run as a business unit of Paychex since Paychex completed its acquisition in April 2025.

Paycor's platform offers onboarding, performance, and learning modules alongside payroll, and its small business bundles are published, starting at $99 a month plus $5 per employee for Basic.

Rippling

Rippling unifies payroll, HR, and IT provisioning on one employee record. Its pricing page is a quote form, but its small-business page starts payroll plans at $8 per user per month plus a $40 monthly base fee.

Its blog starts the core platform at $8 per employee and prices the payroll module separately, at $8 billed annually or $10 billed monthly, so configured quotes run higher than that start.

What each provider actually costs an Oklahoma employer

The table below models published rates at three headcounts for seven of the ten providers, leaving out ADP RUN, Paycor, and Rippling, which appear in the comparison table above. 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.

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

Choosing a payroll provider for Oklahoma

Five questions separate the providers for an Oklahoma employer. Put all five to a vendor during the sales process, when the answers can still change your choice.

Payroll services in Tulsa and Oklahoma City

Payroll services in Tulsa come in two shapes: local bureaus and accounting firms that run payroll for you, and the national platforms above that sell you software to run it yourself. Both file the same returns, because the state sets the forms: the quarterly OES-3 to the Employment Security Commission and withholding returns and payments to the Tax Commission.

A local bureau usually prices per pay run rather than per employee per month, and what you are buying is a named person who answers the phone. That is worth real money if your pay runs are irregular or you have no bookkeeper, and much less if you pay a dozen salaried people twice a month.

A local relationship does not have to mean a local company, either: ADP, one of the national providers above, lists an office in Oklahoma City.

Before you choose

FirstHR is an onboarding and HR platform, not a payroll provider. Running payroll, the duty to file payroll taxes, and benefits administration belong to the providers above, 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. Our onboarding workflows put Form OK-W-4, the federal W-4, and the I-9 on the first-day task list for each new hire, and the completed forms are kept in the employee file. E-signatures on offer letters and acknowledgments, employee records, and document management come with it, for small and growing US teams at a flat $98 a month for up to 10 people or $198 for 11 to 50.

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, which a task with a due date keeps in view. The forms themselves are filled in outside the platform.

Frequently Asked Questions

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

Two at state level plus federal: income tax withholding at three taxable rates, the highest 4.5 percent, and unemployment insurance at 1.5 percent for new employers on a wage base of $24,400 from January 1, 2027 ($25,000 through 2026). Oklahoma adds no local income tax, no state disability program, and no paid family leave contribution.

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. Packet OW-2, revised in November 2025, carries the new withholding tables, and any table showing 0.25 or 2.75 percent is still on 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 predates tax year 2024.

Could Oklahoma eliminate its income tax?

Possibly. A trigger in House Bill 2764 cuts rates by 0.25 percentage points whenever the State Board of Equalization certifies that comparison year collections exceed base year collections plus 1.25 times the projected annual cost of the cut, and enough cuts would reach zero. A declared revenue failure postpones a pending reduction until a later certification, so the path is conditional, not scheduled.

What is the Oklahoma unemployment insurance wage base?

$24,400 per employee from January 1, 2027 ($25,000 through December 31, 2026), down from $28,200 in 2025. With no conditional factor for 2027, contribution rates run from 0.1 to 5.5 percent (0.2 to 5.8 percent under Conditional Factor A in 2026), and new employers pay 1.5 percent. The maximum weekly benefit rises to $703 from $649 as the trust fund improves.

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 that files four no-wage reports in a row returns 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. On June 16, 2026, voters rejected State Question 832, which proposed $15 by 2029, so no increase is scheduled. Because cities are preempted from setting their own rates, the minimum is the same in every Oklahoma town.

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

Twenty days from the hire date. The report goes to the Employment Security Commission on Form OES-112 or online, as 40 O.S. Section 2-802 requires, and electronic filers may instead report twice monthly with submissions twelve to sixteen days apart.

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

No to both. No city or county levies a local income tax, so you never have to sort employees by local tax jurisdiction. There is no state disability insurance and no paid family leave contribution, and workers compensation runs on a competitive private market rather than a state monopoly.
