Kansas Tax Payment Plan Calculator

How Kansas Tax Payment Plans Work

In Kansas, the Kansas Department of Revenue (KDOR) lets most individuals and businesses request a payment plan online, by mail, fax, or email; terms generally run 6 to 24 months, and interest currently runs at 8% a year on the unpaid balance for 2026. A $25 administration fee applies to any plan lasting longer than 90 days. Because interest and penalty keep accruing the whole time, the largest payment amount you can sustain is usually the cheapest path — the calculator above shows that trade-off for your exact balance.

The cost most people miss: a Kansas tax payment plan stops some collection pressure, but it isn't free — KDOR keeps charging interest and penalty on whatever you still owe, and a plan running past 6 months can still bring a tax warrant. Paying even a little more each month can save real money in total.

What's Specific to Kansas

Is a Payment Plan Your Best Option?

A Kansas tax payment plan isn't always the cheapest path. Here's how it compares to the other ways to resolve a tax bill in Kansas:

‍

Before You Apply Online

Consider getting tax help before applying on your own if:

• You can't sustain a monthly payment that clears the balance within about 24 months.
• Your plan is likely to run longer than 12 months, raising the risk of a tax warrant.
• You have missing or unfiled Kansas tax returns.
• You already defaulted on a prior Kansas payment plan.
• You've received a tax warrant, garnishment, or levy notice.
• You owe both Kansas state tax and federal (IRS) tax balances.
• Your business collected sales, use, or withholding tax.
• Your income is unstable or has recently reduced.

Applying online with the wrong setup can lock you into an unaffordable payment amount or cause you to miss a more cost-effective tax resolution option.

Common Mistakes With Kansas Payment Plans

• Choosing a monthly payment too low to clear the balance within a reasonable term
• Forgetting that KDOR keeps charging interest and penalty for the entire life of the plan
• Falling out of compliance — a new unfiled or unpaid return defaulting the plan
• Missing a single payment and defaulting on the whole installment agreement
• Not realizing that a plan lasting more than 12 months can still trigger a tax warrant
• Setting up a Kansas payment plan without coordinating a separate IRS installment agreement if you also owe federal tax
• Assuming a payment plan automatically removes an existing tax warrant, lien, or garnishment
• Not asking about penalty abatement or the Petition for Abatement before locking into a long-term plan

How to Apply in Kansas

Apply online through the KDOR pay-plan portal at debtpay.kdor.ks.gov/iia, or submit Form CM-15 (individuals) or CM-16 (businesses) by mail, fax to 785-291-3616, or email to kdor_kstaxpayplanrequest@ks.gov. The calculator is an estimate to help you pick a payment amount before you apply; KDOR sets official terms and may require financial documentation for larger or longer-term plans.

Does Kansas offer a tax payment plan?

Yes, the Kansas Department of Revenue (KDOR) offers payment plans that let individuals and businesses pay state tax debt in monthly installments. You can apply online through the KDOR pay-plan portal, or by mailing, faxing, or emailing Form CM-15 (individuals) or CM-16 (businesses). KDOR reviews your balance and financial circumstances before approving official terms, and confirmation typically arrives by mail within 14 days.

In Kansas, how long can a payment plan last?

Kansas payment plans typically run between 6 and 24 months, depending on your balance and financial circumstances. Plans that stay within 12 months help you avoid a tax warrant, while longer terms up to 24 months are available but generally require more financial documentation. KDOR sets the exact length on a case-by-case basis, considering your compliance history and total amount owed.

Does Kansas keep charging interest during a payment plan?

Yes, KDOR continues charging interest, currently 8% annually for 2026, plus a penalty of up to 1% per month (capped at 24%) on the unpaid balance for the entire life of the agreement. Refunds you'd otherwise receive are also applied to the balance. Paying the largest amount you can afford each month reduces total interest paid — the calculator above shows exactly how much.

What's the minimum monthly payment in Kansas?

Kansas has no fixed dollar minimum for monthly payments. Instead, KDOR expects an amount large enough to pay off your balance within a reasonable term, generally up to 24 months. If you can't sustain a qualifying payment, options like penalty abatement, a Petition for Abatement, or hardship consideration may resolve your liability more effectively than a standard installment plan.

What happens if I miss a payment in Kansas?

Missing a payment or incurring a new unfiled or unpaid tax liability puts your Kansas payment plan into default. KDOR may then take immediate enforcement action, including wage garnishment, bank levies, or filing a tax warrant, without a lengthy notice period. Contact KDOR's Collections Department right away if you think you'll miss a payment, since acting early may prevent default.

Will Kansas still file a lien if I'm on a payment plan?

It's possible. KDOR files a tax warrant — Kansas's equivalent of a lien — if your payment plan runs longer than 12 months, or if the statute of limitations on your debt is set to expire during the plan's term. A tax warrant is recorded with the district court and can affect your credit and property. Paying off quickly can help you avoid one.

Is a payment plan my best option?

No, it's not always your best option. A Kansas payment plan makes sense if you can afford steady monthly payments and stay current on future filings, but it isn't the cheapest option if your balance is large relative to what you can pay. Penalty abatement or a Petition for Abatement may save more in those cases, and taxpayers who owe both Kansas and the IRS should coordinate both plans carefully.

Do I need to file my returns before a payment plan in Kansas?

Yes, KDOR generally requires all required Kansas tax returns to be filed before it will approve or maintain a payment plan, and taxpayers must keep filing and paying current and future taxes while the plan is active. An unfiled or unpaid new liability can default your existing agreement. File any missing returns first, then request your payment plan to avoid delays or denial.
