Missouri Sales Tax Payment Plan & Resolution
Checklist
Understanding Sales Tax Obligations
Sales tax represents amounts you owe to Missouri for taxes collected from customers but not remitted or assessed by the state based on filings or audits. The Missouri Department of
Revenue identifies these obligations through missed filings, returns filed without payment, audit discrepancies, or assessments for unreported sales.
Filing Frequency Requirements
Missouri determines your filing frequency based on the amount of state tax you collect, not local tax. Monthly filing applies when you collect $500 or more in state sales tax per month, while quarterly filing applies when you collect $500 or less per month but more than $200 per quarter.
Annual filing applies when you collect less than $200 per quarter. The Department reviews your filing frequency annually and notifies you of any changes.
Consequences of Unpaid Sales Tax
Ignoring sales tax obligations triggers escalating collection actions by the state. The Department may send additional notices, assess increased penalties and interest, file a tax lien against business or personal property, garnish wages, or levy bank accounts.
Initial Response Steps
Gather all correspondence from the Missouri Department of Revenue, including the original notice, follow-up letters, and demand notices. Collect copies of sales tax returns filed for the periods in question and business records showing sales, taxable transactions, or payments already made.
Verifying the Assessment
Review the tax periods listed on the notice against your business records to confirm accuracy.
Check whether you actually collected sales tax during those periods and verify the calculation of interest and penalties.
Identify any discrepancies between the state’s claims and your records, documenting them clearly with supporting evidence. Contact the Department at 573-751-7200 for sales tax balance due questions, if you need clarification about which periods are in question.
Payment Plan Application Process
Missouri installment agreements require a minimum monthly payment of $50 and cannot exceed 36 months in duration. Request information about tax payment plan eligibility and application procedures directly from the Department, and ask whether the interest rate continues to accrue during the payment agreement period.
Submitting Your Application
Complete all required forms and provide supporting documentation as specified by the
Department. Send your application using certified mail or another method that provides proof of delivery, and include a cover letter stating your intent to resolve the tax debts while referencing the notice number and tax periods involved.
Making Payments Under the Plan
Follow these steps once the Department approves your tax payment plan
1. Pay the agreed-upon amount on the dates specified in your written payment agreement.
2. Use the payment method designated by the Missouri Department of Revenue for all scheduled monthly payments.
3. Include the notice or account number on each payment to ensure proper posting to your account.
4. Keep records and receipts of every payment made throughout the duration of the plan.
5. Continue making payments even if you receive additional correspondence from the state during the plan period.
Monitoring Your Account
Track your remaining balance as the Department applies each payment to your account.
Review updated statements or notices the Department sends you to confirm accurate posting, and contact the Department immediately if a payment does not appear credited or if you notice any discrepancies in your account balance.
Plan Completion and Confirmation
Continue making all scheduled payments until the Department confirms satisfaction of the tax debts. Request written confirmation that your obligation has been resolved and the collection case has been closed, and retain all documentation of tax payment plan completion for your permanent records.
Common Errors to Avoid
Missing response deadlines can forfeit resolution options and continue collection activity.
Submitting incomplete applications delays processing and may result in the denial of your payment agreement request.
Never assume a notice will disappear if ignored, or stop making payments before the
Department formally approves your plan. Maintain detailed records of all correspondence, notices, and payments to verify compliance and dispute errors.
Filing a tax return does not satisfy a payment obligation; both actions are required separately.
Respond promptly to all Department requests for additional information or documentation during the application process, as failure to provide requested documentation or financial statements may delay approval.
Understanding Tax Liens and Collection Actions
The state of Missouri may file a tax lien when prior notices remain unresolved and tax debts become final. This lien attaches to real or personal property you own or acquire after filing and may be recorded with the circuit court, giving it the effect of a default judgment.
Resolving the matter requires full payment of the debt or approval of a payment agreement, and the lien remains on record until the Department issues a formal release.
Maintaining Future Compliance
After resolving past-due sales tax through a payment plan, maintain the current filing and payment status for all future periods. Continue to file each tax return by its due date, even while paying off prior balances under an installment agreement.
