When Are Kansas Property Taxes Due? 2026 Rates, Dates & Exemptions

Kansas property taxes are a significant expense for homeowners, with deadlines that catch many residents off guard. If you own property in Kansas, you need to know exactly when Kansas property taxes are due: December 20 for the full annual amount, or you can split payments with half due by December 20 and the remainder by May 10. With an effective state property tax rate of 1.41%, understanding these dates and rules helps you avoid costly late penalties.

When Are Kansas Property Taxes Due?

Kansas property taxes follow a semi-annual payment schedule that differs from many other states. The primary due date is December 20 each year for full payment. However, you have flexibility: you can pay half your annual bill by December 20 and the remaining half by May 10 of the following year.

Always confirm exact deadlines with your county treasurer, as some counties may have slight variations in how they process payments. Missing either deadline can trigger penalties and potential tax liens.

Schedule	Due Date	Notes
Full payment	December 20	One lump-sum payment for the entire year
First installment	December 20	Half of your annual property tax bill
Second installment	May 10	Remaining half of your annual property tax bill

Confirm final deadlines with your county treasurer's office.

Kansas Property Tax Rates

The effective property tax rate in Kansas is 1.41% as of 2026, which is moderate compared to many states nationwide. However, actual rates vary by county and municipality, so your specific bill depends on your home's assessed value and your local jurisdiction's millage rates.

For example, a Kansas homeowner with a property valued at $210,000 (the state's median home price) would pay approximately $2,961 annually at the state average rate. County assessors determine assessed values every four years, so your taxes may change even if property values remain stable.

Kansas Property Tax Exemptions

Kansas offers several property tax exemptions that can significantly reduce your annual bill. Homestead, senior, and veteran exemptions vary by county, so you must check with your county assessor to determine eligibility and application procedures.

Common exemptions include:

• Homestead exemptions for primary residences (varies by county)
• Senior exemptions for older homeowners (typically age 65+)
• Veteran exemptions for military service members and their surviving spouses
• Disability exemptions in some counties

Each county administers these exemptions independently, so the amount of tax relief you receive depends on where you live. Contact your county assessor's office early in the tax year to apply, as deadlines vary.

How to Pay Kansas Property Taxes

You can pay property taxes through your county treasurer's office, which handles all tax payments for your jurisdiction. Most Kansas counties accept payments in person, by mail, or online through their official websites.

If you have a mortgage, your lender may include property taxes in your monthly PITI (principal, interest, taxes, insurance) payment through an escrow account.

What Happens If You Miss the Deadline?

Missing the December 20 or May 10 deadline carries serious financial consequences. Late payments typically incur a penalty of 1% to 2% per month, compounding quickly and adding hundreds of dollars to your bill.

If delinquency continues beyond a certain period (usually 12–24 months depending on the county), the county may place a tax lien on your property. This lien can affect your credit score, prevent you from refinancing your mortgage, and ultimately lead to a tax sale of your home. Contacting your county treasurer immediately if you miss a deadline can prevent escalation to a lien.

Property Taxes and Your Mortgage Payment

If you financed your Kansas home with a mortgage, your lender likely requires you to pay property taxes through an escrow account bundled into your monthly payment. This means property taxes are automatically deducted from your escrow account and paid to the county on your behalf—no separate December 20 payment needed.

However, if you own your home outright or pay taxes directly, you're responsible for submitting payment by the deadline. Understanding the difference between escrow and direct payment is crucial. Use our mortgage calculator for Kansas to see exactly how property taxes factor into your monthly housing costs.
