Federal withholding uses the 2026 IRS Publication 15-T Percentage Method tables. Supports both 2019-and-earlier W-4 (allowance-based) and 2020+ W-4 (Steps 2–4). Federal withholding allowance: $4,300. Social Security wage base: $184,500.
State withholding, where applicable, uses an estimated rate. For precise calculations, consult your state's withholding tables or a qualified payroll professional.
Start with your gross pay, subtract federal income tax using the 2026 IRS Publication 15-T brackets, subtract state income tax if Kansas has one, then subtract Social Security (6.2% up to the annual wage base) and Medicare (1.45%). What's left is your net, take-home pay. Use the calculator above for an instant estimate.
Whether Kansas withholds a separate state income tax depends on state law. If it does, this calculator's state section estimates it alongside your federal withholding. If Kansas doesn't tax wages, only federal tax and FICA are withheld from your paycheck.
The 2026 Social Security wage base is $184,500. Employees pay 6.2% of wages up to this limit each year. Earnings above $184,500 aren't subject to Social Security tax, though the 1.45% Medicare tax (plus a 0.9% surtax above $200,000 for most filers) applies to all wages.
For 2026, the IRS Publication 15-T Percentage Method standard withholding schedule for a single filer is: 0% up to $7,500; 10% from $7,500 to $19,900; 12% from $19,900 to $57,900; 22% from $57,900 to $113,200; 24% from $113,200 to $209,275; 32% from $209,275 to $263,725; 35% from $263,725 to $648,100; and 37% above $648,100. Married and head-of-household filers use wider brackets.
The IRS updates federal withholding tables annually in Publication 15-T, typically released in December for the following year. State withholding tables vary by state — some update annually, others less often. Always confirm you're using current-year tables before processing payroll.
