What are Kansas state income tax and unemployment insurance rates in 2026?

Kansas moved from three income tax brackets to two in June 2024 when Governor Laura Kelly signed Senate Bill 1 during a special legislative session. The old top rate of 5.7% dropped to 5.58%. The 5.25% mid-rate fell to 5.20%. The lowest 3.1% bracket was eliminated entirely.

The same SB 1 reform raised the Kansas personal exemption. Single filers now claim $9,160 (up from $2,250). Married couples filing jointly claim $18,320 (up from $4,500). Each dependent adds $2,320. Standard deductions are $3,605 (single) and $8,240 (married filing jointly).

Social Security income is fully exempt from Kansas income tax for all filers, also effective from tax year 2024. For employees nearing retirement in your Kansas workforce, this is a meaningful take-home improvement.

The K-4 (Kansas Employee's Withholding Allowance Certificate) is the state equivalent of the federal W-4. Employees hired after 31st December 2007 must complete a K-4 before or on the date of employment if they earn Kansas source wages. The current revision is K-4 (Rev. July 2024). If an employee does not submit a K-4, you withhold at the single rate with no allowances.

The Kansas Department of Revenue assigns your filing frequency based on your annual withholding volume. The annual reconciliation Form KW-3 is due 15th February of the following year, filed together with employee W-2s. A 15% penalty applies to late deposits or returns.

Kansas House Bill 2570, signed by Governor Laura Kelly on 24th April 2024, made two material changes. First, it replaced the fixed $14,000 wage base with an annually-indexed formula tied to a percentage of the statewide average annual wage (SAAW). The 2026 wage base is $15,100. Second, it restructured Kansas's 13 unemployment rate schedules.

Under the HB 2570 restructured schedules, experienced employer rates range from 0.0% to 6.95% on the 2026 schedule in effect (HB2570 Schedule C). The most positively rated employers can now reach a 0% rate, a floor unavailable under the old structure. New non-construction employers are assigned 1.75%. New construction-industry employers are assigned 5.55%, reflecting the historically higher claims patterns in that sector.

Rates are experience-based: the ratio of unemployment benefits charged to your account versus your taxable wages reported. A clean claims history moves you down the schedule. The Kansas Department of Labor mails rate notices annually.

Federal FUTA applies separately: 6.0% on the first $7,000 of wages per employee, reduced to an effective 0.6% for Kansas employers who pay state UI on time (the standard 5.4% FUTA credit). That's a maximum of $42 per employee per year in federal unemployment tax. See IRS Topic 759 on FUTA for full details. Kansas's continued good standing means the credit holds.

Kansas has no state disability insurance (SDI) and no state paid family leave (PFL) programme. That keeps the statutory employer cost below states like California or New York. Kansas income tax withholding is an employee-side cost: you administer it, you don't pay it as an employer contribution.

The 118% loading is leaner than most US states with SDI or PFL mandates. Kansas's lack of state-level leave programmes means your variable cost mostly follows FICA and UI contributions, which are the same for every US employer on this salary.

You pay from $599 per employee per month, flat. Statutory costs above sit on top of gross salary and pass through at cost on every Teamed invoice, itemised line by line. You pay in dollars, euros, or pounds. The fee is the same in any currency: Zero FX mark-up. No hidden spread, no premium for cross-currency billing. The invoice fits on one screen. That's the point.

Contractor through EOR to entity: once your Kansas headcount crosses the graduation point (roughly 5 to 8 employees at mid-market salaries), running your own entity becomes cheaper than the EOR fee on the same gross. Use the EOR vs Entity Crossover Calculator to see exactly where that line sits for your team. We tell you when you've crossed it. The EOR model is right until when the model no longer fits.

Kansas income tax now starts at 5.20%, not at 3.1%. The old lowest bracket is gone. An employee earning $22,000 pays Kansas income tax on every dollar; the rate is 5.20% throughout. The higher personal exemption ($9,160 single) offsets this at lower income levels, but the bracket structure simplifies withholding calculations considerably compared to the three-bracket pre-2024 system.

Federal FMLA applies at 50 or more employees within 75 miles. Kansas has no state equivalent. Below 50 employees, the leave policy you write in the offer letter is the policy you run. Social Security income has been fully exempt from Kansas tax since tax year 2024. If any of your Kansas employees are in a phased-retirement arrangement or drawing Social Security, update their K-4 withholding accordingly.

New hire reporting is due within 20 days of hire date, submitted through KansasEmployer.gov. The state also accepts Form W-4 mailed or faxed to the Kansas New Hire Directory. Employees returning after a gap of 60 or more consecutive days count as new hires for reporting purposes. There is no monetary penalty for late reporting in Kansas, though the obligation is statutory under federal and state law.

Kansas has no state-level overtime pay exemption at present. A similar overtime deduction did not make it into Kansas law. Federal FLSA overtime rules (1.5x for FLSA non-exempt employees over 40 hours per week) apply statewide without modification. For more on how Kansas handles overtime, see the Kansas wage, overtime, and meal-break guide. A real HR and legal expert with deep local employment-law expertise monitors Kansas legislative changes and flags anything that affects your payroll before it takes effect.
