For many working-class and middle-income taxpayers in Missouri, owing back taxes can create severe financial pressure. Whether due to a job loss, unexpected medical expenses, or simple oversight, falling behind on state tax obligations is more common than you might think.
Thankfully, the Missouri Department of Revenue (DOR) offers tax payment plans—formally known as installment agreements—that allow individuals and businesses to pay off their Missouri back taxes over time in manageable monthly payments. These plans can help avoid aggressive collection actions like wage garnishment or tax liens.
Understanding your options, responsibilities, and the application process is key to using these programs successfully. This guide explains Missouri’s payment plans, who qualifies, and what you must do to apply and stay compliant.
A Missouri tax payment plan is a legal agreement with the Missouri Department of Revenue (DOR) that lets some taxpayers pay off their back taxes over time instead of all at once. These agreements, which are also called installment agreements, are for people and businesses that can't pay in full but want to avoid more penalties and enforcement actions.
This plan helps ease immediate financial stress and keeps the state from taking legal action, such as levies, liens, or other actions. If you follow the terms of your plan and make your payments on time, the Missouri Department of Revenue usually stops more aggressive collections once your installment agreement is approved.
Signing up for a payment plan also helps you maintain your access to financial opportunities. If you don't have to deal with garnishments or liens, getting a loan, mortgage, or lease may be easier. It demonstrates your sincere efforts to settle your tax debt and provides you with some financial flexibility.
You should consider a Missouri tax payment plan if you owe back taxes and are unable to pay the full balance up front—but you do have enough income to make consistent monthly payments. This includes people who have fallen behind due to temporary hardship, job loss, or unexpected expenses but want to catch up responsibly without facing penalties or legal consequences.
The best time to apply is as soon as you know you won’t be able to pay in full. Waiting can lead to the situation getting worse—both financially and legally. If you ignore tax notices or delay contacting the DOR, you may face collection actions such as bank levies, wage garnishments, or property liens. These actions increase stress and may damage your credit or interrupt your income.
A payment plan also buys you time to reorganize your finances, budget more effectively, and protect your household from aggressive collection actions. Whether dealing with individual income tax or business tax liabilities, enrolling in an installment agreement is an innovative and responsible step toward getting back on track.
Missouri installment agreements allow individuals or businesses to repay their tax debt monthly for up to 36 months.
You may request an agreement lasting up to three years, depending on how much you owe and your ability to make consistent payments.
The minimum monthly payment is $50, and interest continues to accrue on the unpaid balance at an 8% annual rate in 2025.
The Missouri Department of Revenue typically halts enforced collection actions during an active installment agreement, providing you with a buffer as long as you maintain good standing.
If you also owe federal back taxes, you must deal with the IRS separately from the Missouri Department of Revenue.
The IRS offers short-term payment plans (up to 180 days) and long-term installment agreements for larger balances.
State and federal payment plans are completely separate. Each has its terms, forms, and eligibility rules.
You must apply to each agency individually to address state and federal debts. There’s no automatic coordination between the Missouri DOR and the IRS.
Taxpayers can choose between short- or long-term plans based on the amount owed and how quickly they can repay the debt.
Short-term plans are ideal for those who can pay off their balance within a few months, while long-term agreements are structured for payments over one to three years.
Short-term plans avoid additional interest but require more aggressive budgeting. Long-term plans offer smaller monthly payments with more time but will accrue more interest overall.
Certain conditions must be met before you can request a tax installment agreement in Missouri.
You must have filed all required tax returns and not be in bankruptcy. The DOR will only consider your request if you can make consistent monthly payments.
All past-due balances—regardless of tax type or year—must be included in a single payment plan. Missouri does not allow multiple concurrent agreements.
Once approved, taxpayers are expected to remain compliant with specific rules.
You must make all payments on time and file all future tax returns. Missing a new filing or payment could result in default.
The minimum payment is $50, and you’ll be asked to document your proposed payment amount and payment method, especially if applying by mail.
Before applying, make sure you collect the necessary documentation.
You’ll need your Social Security Number (or business tax ID), recent tax notices, banking info, and a rough monthly budget for what you can afford.
You can apply online, by mail, or by phone.
The fastest way to apply is through the DOR website at dor.mo.gov/taxation/payment-options/. Online applications often receive instant responses and allow for a secure banking setup.
You can fill out and submit Form 4338, the Tax Payment Installment Agreement Request. Mail it to:
Taxation Division
P.O. Box 1002
Jefferson City, MO 65105-1002
Call the Missouri Department of Revenue at (573) 751-7200 to request a payment plan over the phone. Be prepared to verify your identity and account details.
Make sure your application is filled out completely and accurately.
Include all required fields, such as your name, contact info, tax periods, and proposed payment amount. Errors or omissions can delay approval or trigger rejection.
You’ll need to choose how you want to make your monthly payments.
You can pay via electronic withdrawal (recommended), mailed checks, or credit/debit card.
E-checks have a small 50¢ fee, while credit card payments incur a 2.0% + $0.25 fee per transaction. Choose the method that works best for your budget and schedule.
After submission, track your application for confirmation or response.
Online applications may get same-day approval. Mailed applications can take several weeks.
If rejected, call the Missouri DOR immediately to ask what went wrong and whether you can reapply or revise your request.
Understanding the key differences between plan features can help you make the best choice.
Compare whether short- or long-term plans make sense for you, how much you can afford monthly, and which payment method minimizes fees.
Every payment type comes with potential transaction costs.
E-checks cost 50¢ per payment. In addition to a 25¢ processing fee, credit/debit cards charge 2% of the total amount paid. Mailing checks may cause payment delays and should be tracked.
In some cases, other payment options might be more cost-effective.
If you can secure a personal loan or help from family at a lower interest rate, paying the tax debt in full may be better and avoiding long-term accruals may be better.
Missouri will apply any future state tax refunds to your balance. This can help reduce your debt faster, but you must continue making regular payments.
Once approved, managing your agreement correctly helps you stay in good standing.
Always pay on or before the due date to avoid penalties and default.
Continue filing and paying all future taxes. New debts can’t be added to your existing plan.
If your bank account changes or you move, notify the Missouri DOR immediately to prevent missed payments or notices.
Your refunds will be used to reduce your outstanding debt.
Any Missouri tax refunds you receive will automatically be applied to your balance.
Refund offsets do not count as regular payments. You must still make your scheduled monthly payments even if a refund was applied.
Failing to follow your agreement can have serious repercussions.
If you miss payments or file late returns, your plan may be canceled.
Missouri may garnish your wages, file a lien on your property, or refer your account to collections. These actions can damage your credit and finances.
If your situation changes, please address the issue promptly.
Call the Missouri DOR when you realize a payment will be missed or your situation changes.
You can reinstate the agreement or request a lower monthly payment.
Any unfiled tax returns must be submitted before the DOR will reinstate a defaulted agreement.
This is a debt settlement program available in limited situations. You may be eligible for a settlement if you cannot afford to pay even with a payment plan. You must provide extensive documentation showing the inability to pay. Approval is not guaranteed.
You can request changes if your finances have changed.
If your income drops or expenses rise significantly, contact the DOR to request a lower monthly payment.
You may be asked to submit proof of income, expenses, and hardship to support your request.
In rare cases, the DOR may delay enforcement.
If you cannot pay due to a significant hardship (e.g., disability, disaster), you may qualify for a temporary pause in collection.
No, the Missouri Department of Revenue requires all outstanding tax returns to be filed before it will consider you eligible for a tax payment plan. Filing compliance is a strict requirement. Your request will be automatically denied if you have unfiled returns for any year or tax type. Before applying, submit every missing return to avoid enforcement actions like liens or garnishments.
A tax payment plan in Missouri can last for up to 36 months, or three years, depending on your balance and financial circumstances. The maximum term provides flexibility to make lower monthly payments, but longer repayment periods also result in more interest accumulating over time. The Department of Revenue will review your proposed monthly payment and total balance to determine whether your requested timeline is acceptable.
The minimum monthly payment for a Missouri installment agreement is $50. However, the DOR strongly encourages you to propose the highest amount you can afford to reduce your balance faster and limit interest accrual. Paying more than the minimum shortens your repayment period and shows good faith, which may be helpful if you ever need to request a plan modification or reinstatement.
Yes, interest continues to accrue on your unpaid balance throughout your payment plan. As of 2025, the statutory interest rate in Missouri is 8% per year. Some penalties may also continue to apply. This means that the longer you take to pay off your debt, the more it will ultimately cost you. Paying more than your minimum amount helps reduce this burden.
Yes, you can pay off your tax installment agreement for Missouri early at any time, and there is no penalty for doing so. Early payoff is encouraged because it reduces the interest on your balance. If you come into extra funds, such as a bonus or tax refund, applying them toward your tax debt can help you become debt-free faster.
The Missouri Department of Revenue may still file a tax lien against you even if you make payments through an installment agreement. A lien is a legal claim against your property that secures the state’s interest while the debt is still outstanding. The lien does not mean you’ve defaulted, but it remains until your entire balance is paid in full and then is released.
While in an active installment agreement, any state tax refunds you're owed will automatically be applied to your outstanding tax balance. This helps reduce your total debt but does not replace your scheduled monthly payments. You are still responsible for making your agreed-upon payments on time each month, even if your refund has been partially or fully applied to your balance by the Missouri DOR.
