Kansas has two income tax rates, 5.2% and 5.58%, and its own withholding certificate, the K-4. The K-4 allowances carry real weight: the first one (two on the Joint rate) shields $9,160 a year, and each additional allowance shields $2,320.

2026 tax year, rules last verified November 12, 2026. An estimate, not tax advice. How we calculate
Each extra dollar you earn loses about 25¢ to taxes, but across all your pay the average is 20¢. A raise never lowers your take-home: only the dollars above a bracket line pay the higher rate.

|---|---|---|
| $15,000 | 8.4% | 12.8% |
| $30,000 | 15.4% | 24.9% |
| $45,000 | 18.6% | 25.2% |

Same pay, W-4 and benefits; each state’s default withholding answers, no local taxes. Take-home per week:
Kansas uses the KW-100 percentage formula. Your employer adds up the dollar value of your K-4 allowances, divides by the number of paychecks in the year, subtracts that from this paycheck’s wages and applies the Single or Joint table.
On the Single rate, the first $3,605 a year after allowances is withheld at 0%, then 5.2% up to $26,605 and 5.58% above. On the Joint rate the bands are $8,240 and $54,240.
Kansas follows federal taxable wages, so 401(k) deferrals and pre-tax health premiums reduce your Kansas withholding.
| K-4 rate | 0% | 5.2% | 5.58% |
|---|---|---|---|
| Single (incl. head of household) | up to $3,605 | $3,605–$26,605 | over $26,605 |
| Joint | up to $8,240 | $8,240–$54,240 | over $54,240 |
Allowances: $9,160 for the first (first two on Joint), $2,320 for each one after that, divided by your pay periods.

None. Kansas cities and counties don’t tax wages. If you live in Kansas but work in Kansas City, Missouri, the city’s 1% earnings tax applies to that pay, and Kansas gives a credit for Missouri state tax on your return.
Kansas has no state disability, paid family leave or employee unemployment deduction. Unemployment insurance is paid by employers.
Kansas has no reciprocal agreements. Missouri residents working in Kansas have Kansas tax withheld and claim a credit at home; Kansans working in Missouri usually have Missouri tax withheld.
On the Single rate with 1 allowance, about $40.40. With no K-4 on file (0 allowances) it is $50.23.
Joint only if you’re married and your spouse has no income. If you both work, each of you should choose Single, or you will likely owe at tax time.
Usually 1 for yourself, 1 for a non-working spouse, 1 per dependent, and 2 if you file as head of household. Every allowance after your personal exemption lowers Kansas withholding by about $2.32 a week at the 5.2% rate.
If your employer withholds federal tax on the bonus at a flat percentage, Kansas withholds a flat 5%. If the bonus is added to your regular pay, it goes through the normal formula.
