Differences Between Kansas Form K-4 and the Federal Form W-4:

State and federal tax policies and laws differ. To allow for these differences Kansas developed the Kansas Form K-4. You will notice the following benefits with the Kansas form:

1. It is now optional to claim the "married" allowance rate for married individuals.

  • Instead, they may claim "single" to allow for appropriate withholding for two married spouses earning Kansas income.

2. Dependents are not counted as allowances more than once.

3. An extra amount can now be specified for your Kansas wage withholding.

4. Certain credits that do not apply to Kansas filers have been omitted.

The Kansas Form K-4 should be completed as soon as an employee is hired or taxable payments begin. The amount of tax withheld should be reviewed each year. New forms should be filed whenever there is a change in either the marital status or number of exemptions of the individual. If an employee does not complete a Kansas Form K-4, the employer must withhold wages at the single rate with no allowances.
