Each state has unique income tax withholding rules. Below are Kansas's 2026 withholding instructions, including allowance calculations, standard deduction adjustments, and the percentage method for determining tax due.
Employers must also adhere to federal income tax withholding rules. More information can be found here about federal rates.
Alternatively, employers can automatically calculate payroll withholding by using ezPaycheck.

Kansas allows personal allowances similar to old federal rules. An employee starts with 1 for themselves (if not claimed as dependent). If married and the spouse does not work, the employee may claim 1 additional allowance for the spouse (but if both spouses work, they are advised not to double-claim this). A head of household can claim 2 allowances (instead of 1) for that status. Each dependent qualifies for 1 allowance. Kansas does not list extra allowances for age or blindness on form K-4.
| Component | Allowances | Notes |
|---|---|---|
| Yourself | 1 allowance | If not claimed as dependent |
| Spouse | 1 allowance | If spouse does not work (don't double-claim if both work) |
| Head of Household | 2 allowances | Instead of 1 for HOH status |
| Each Dependent | 1 allowance | Per dependent |
Total Allowances = Yourself + Spouse (if applicable) + HOH Bonus + Dependents
All personal exemptions on the KS return are $2,250 each; the form keeps it simple with one per person. No additional allowances for age 65+ or blindness.

Subtract the biweekly Thrift Savings Plan contribution from the gross biweekly wages.
Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program, and flexible spending account - health care and dependent care deductions) from the amount computed in Step 1.
Multiply the adjusted gross biweekly wages times 26 to obtain the annual wages.
Determine the exemption allowance by applying the following guideline and subtract this amount from the result of step 3 to compute the taxable income.
Exemption Allowance = $2,320 × Number of Exemptions Claimed on Federal Form K-4
Apply the taxable income computed in step 4 to the tax withholding table to determine the Kansas tax withholding.
Divide the annual Kansas tax withholding by 26 to obtain the biweekly Kansas tax withholding.
