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.

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.
