FAQ on Kansas Form K-4

Last updated: March 29, 2016

Have Questions About Kansas Form K-4?

Can the employee select a different allowance rate than what they claim on their federal W-4 form with the new Kansas K-4 Form?

Yes. A married individual can now elect to withhold at the "single" allowance rate. This allows a higher percentage of withholding for two income married spouses filing joint. Single individuals should always select the "single" allowance rate.

Can my spouse and I both claim dependents?

The Department of Revenue encourages spouses to only claim their dependents on the higher wage earner's K-4. If both spouses claim the same dependents, there is an increased risk of owing taxes when filing your income tax return.

Can I claim my spouse as a dependent?

Only claim your spouse if your spouse does not work.

Do I qualify for head of household?

Generally, you qualify only if you:

  • Are unmarried

  • And pay more than 50 percent of the cost of keeping up a home for yourself and for your dependent(s).

Can I claim dependents if someone has claimed me as a dependent?

Yes, as long as no single dependent has been claimed by more than one person at any time.

Can I adjust my Kansas K-4 Form for special situations?

You should make changes to your withholding allowance only in situations that affect your income tax filing status. Changing your Kansas Form K-4 so that it differs from your filing status may increase your risk of owing taxes. You also risk being subjected to underestimate penalty, when filing your income tax return.

Who do I contact to verify I am exempt from withholding?

To qualify for exempt status you must verify with the Department of Revenue that:

  1. Last year you had the right to a refund of all State taxes withheld because you had no tax liability; 

  2. OR This year you will receive a full refund of all State income tax withheld because you will have no tax liability.
