How Kansas state tax withholding works
Kansas taxes wage income, so your employer withholds Kansas income tax from each paycheck in addition to federal tax. You tell your employer how much to withhold on Form K-4 (Kansas Employee's Withholding Allowance Certificate), the state’s counterpart to the federal Form W-4.
For 2026, Kansas uses graduated tax rates. Each rate applies only to the income within its band — the single-filer schedule is:
| Rate | Taxable income over |
|---|---|
| 5.2% | $0 |
| 5.58% | $23,000 |
Kansas’s standard deduction is $3,605 (single) and $8,240 (married filing jointly).

Kansas vs. federal withholding
Your Kansas and federal withholding are figured separately. Federal withholding follows the IRS Publication 15-T tables and your Form W-4; Kansas withholding follows the state’s own rates and your Form K-4. Getting one right doesn’t guarantee the other — this calculator handles both so you don’t owe a surprise bill to either the IRS or Kansas.
Important Kansas notes
- Kansas has two brackets (5.20% and 5.58%) for 2026.
