Kansas Biweekly Paycheck Calculator 2026

Here is exactly what your biweekly paycheck looks like in Kansas at common annual salary levels in 2026. Calculated for a single filer, standard W-4, biweekly pay frequency, no pre-tax deductions.

Single filer · standard W-4 · biweekly pay (26 periods/yr) · no pre-tax deductions · 2026 IRS withholding tables · Kansas published 2026 withholding method. Actual paychecks vary based on filing status, allowances, and deductions.

Kansas withholds state income tax from every paycheck. Your biweekly paycheck includes these deductions:

• Federal income tax (2026 IRS withholding tables)
• Kansas state income tax (withheld each pay period)
• Social Security tax — 6.2% on wages up to $184,500
• Medicare tax — 1.45% on all wages
• Employee benefit deductions

A biweekly pay schedule means you receive a paycheck every two weeks — 26 paychecks per year. To find your gross biweekly pay, divide your annual salary by 26:

Two months per year you will receive three biweekly paychecks instead of two. This is sometimes called a "three-paycheck month." Because benefit deductions are often fixed per paycheck, the extra check can feel larger than usual.

Your net biweekly paycheck in Kansas depends on your annual salary, W-4 filing status, Kansas state withholding elections, retirement contributions, health insurance deductions, and any additional withholding.

The KW-100 annual percentage method takes your biweekly gross, multiplies it out to a full year, applies the Kansas bracket table and standard deduction, then divides the result across 26 periods. It does not tax the paycheck in front of it.

That is why a single irregular biweekly period produces a state line that looks wrong. A check containing retro pay or a bonus annualizes to an income you do not earn, so Kansas over-withholds on that period and the excess is recovered at filing rather than corrected in the next paycheck.

Kansas requires its own Form K-4 and does not accept the federal W-4 as a substitute for state withholding purposes. Employees who only ever filled in a federal form can end up withheld at the default single-with-zero treatment on all 26 biweekly checks.

This is a common source of over-withholding for married Kansas employees, because the federal form's married setting does not carry across. If your Kansas line looks high relative to the table above, the K-4 on file is the first thing to check.

Kansas has no reciprocal agreement with Missouri, which matters more here than almost anywhere else because the Kansas City metropolitan area straddles the state line. A Kansas resident working on the Missouri side has Missouri tax withheld from every biweekly check, plus the Kansas City earnings tax if the worksite is inside city limits.

Kansas relieves the state-level double taxation with a credit at filing, but the city earnings tax has no such offset — it is simply a cost of working at that address. None of it appears in the Kansas figures above.
