Missouri State Tax Enforcement Decision Checklist
Missouri state tax enforcement refers to actions taken by the Missouri Department of Revenue when a taxpayer has unfiled returns, unpaid taxes, or unresolved compliance issues.
Enforcement can include notices, wage garnishments, asset levies, or license suspension under specific statutory authority.
Understanding what enforcement means and recognizing the early stages helps taxpayers take action before collection actions become more serious. Most enforcement actions are preceded by multiple notices, giving taxpayers opportunities to respond.
What This Issue Means
Missouri state tax enforcement is an administrative collection action taken when a tax liability remains unpaid or a required return remains unfiled. An enforcement decision represents the state’s determination that it will now pursue collection through specific legal tools beyond routine billing notices.
This stage means the state has decided to move forward with collection methods that may directly affect your income, assets, or professional standing. Enforcement can occur for income tax, sales tax, or other state tax types, depending on your filing history and circumstances.
Why the State Issued This Action
The Missouri Department of Revenue issues enforcement actions when standard notice and payment procedures have not resolved a tax liability. Common triggers include unfiled tax returns, unpaid tax balances that have gone unresponded to, or failure to comply with a payment plan agreement.
Missouri Revised Statutes Chapter 143 establishes a statutory notice sequence that the
Department follows: Request for Return, Notice of Proposed Changes, Notice of Balance Due,
Notice of Deficiency, 10-Day Demand for Payment, then Lien or Administrative Judgment.
Collecting unpaid taxes and ensuring compliance with Missouri tax law remain the state’s primary goals.
What Happens If This Is Ignored
If a Missouri state tax enforcement notice is ignored, the Department typically pursues collection through available legal tools. These may include wage withholding through garnishment, bank account levies, or claims against refunds.
Under Missouri law, professional licenses will be suspended if a taxpayer fails to pay state taxes or file state tax returns and does not resolve the delinquency within 90 days of being notified by the Department. The longer an enforcement action goes unaddressed, the more costly and intrusive collection efforts typically become. Ignoring tax bills does not make the debt disappear and generally increases the total amount owed through penalties and interest.
What This Does NOT Mean
Receiving an enforcement notice does not automatically mean your wages will be garnished immediately or your bank account will be frozen today. Criminal prosecution or arrest does not occur because tax enforcement in Missouri is a civil, administrative process.
Not all collection actions are final, as most enforcement actions allow for response, negotiation, or resolution steps. An enforcement decision does not eliminate your right to dispute the underlying tax liability or request relief from penalties based on reasonable cause. Having wages garnished does not prevent you from filing future tax returns or receiving an income tax refund, though refunds may be applied to the outstanding tax debt.
Checklist: Missouri State Tax Enforcement Response
Steps
1. Review the enforcement notice carefully: Read the entire notice from start to finish.
Identify the tax type, note the tax year or years involved, and record the total amount claimed due, including penalties and interest. Locate the notice date and any deadline for response.
2. Gather related tax documents: Locate any previous notices or tax bills about this tax liability. Find copies of the relevant tax return, whether filed or unfiled. Collect pay stubs, business records, or income documentation for that tax year.
3. Verify the tax liability accuracy: Confirm the tax year and filing status listed on the notice match your records. Check that the income tax or sales figures cited are accurate to your knowledge. Determine if you filed a return for that year and, if so, when.
4. Contact the Missouri Department of Revenue immediately: Call the number listed on the notice during posted business hours. Explain that you received an enforcement notice and want to understand the debt. Ask for clarification on any items you do not understand and request information about available payment or resolution options.
5. Determine if an unfiled return is the root issue: Ask the Department whether the liability is based on an unfiled return or an assessed liability. If a return was never filed, ask for the Department’s explanation of how the assessment was determined. Clarify whether filing a return now will resolve the issue or if the debt still stands.
6. Review payment and installment options: Ask whether the Department offers payment plans, often called installment agreements. Inquire about the terms, such as monthly payment amounts and total duration. Determine whether penalties and interest continue to accrue during a payment plan and how tax payments will be applied to the balance.
7. Explore penalty relief if applicable: Ask whether penalties can be abated or reduced based on reasonable cause, such as medical issues or natural disasters. Understand that penalty relief is not automatic, and the Department reviews each request on a case-by-case basis. Provisions vary by tax type, so contact the Department directly or submit written requests with supporting documentation.
8. Request written explanation: Send a written response to the address on the enforcement notice. Include your name, address, and the notice reference number.
Briefly explain your situation or dispute, if applicable, and ask for written clarification of specific items you questioned.
9. Do not ignore the payment deadline if one exists: Reread the notice to determine if a payment deadline is stated. If a deadline exists, mark it on your calendar. Contact the
Department immediately if you cannot meet the deadline, as letting it pass without communication typically triggers collection action.
10. Follow up within the timeframe provided: Wait for the Department’s written response if you submitted a letter. If no response timeframe was given, follow up after 10 to 15 business days. Keep records of all communication attempts and dates.
Understanding the Notice of Deficiency
The Notice of Deficiency, also called Assessment of Unpaid Tax, includes a critical 60-day deadline to file a written protest with the Missouri Department of Revenue under state statute.
Taxpayers living outside the United States have 150 days to respond.
After this deadline expires, the assessment becomes final, and you lose the legal right to appeal. This is the last opportunity to dispute the liability before enforcement begins. Resolving tax bills at this stage prevents additional collection actions and protects your income tax refund from being intercepted.
What Happens After This Is Completed
After completing the checklist steps, the Missouri Department of Revenue typically responds with either a resolution agreement, an explanation of next steps, or further information about the debt. Approved payment plans result in the state providing payment instructions and beginning collection according to the agreed schedule.
Enforcement action that proceeds leads to the state notifying you of the specific collection method being used, such as wage withholding or bank levy. The Department may intercept your refund and apply it to the outstanding balance until the debt is resolved.
Common Mistakes to Avoid
Ignoring the notice entirely does not make it disappear and typically results in collection action without further delay. Missing any stated deadline generally allows the state to proceed with collection immediately.
Sending incomplete information when disputing the debt may not be useful to the Department, so provide clear documentation. Not keeping records of communication makes it difficult to track your case, so document when you call, email, or write to the Department. Assuming the garnishment amount is correct without reviewing your own records or the state’s documentation could result in overpaying or failing to catch errors.
Statute of Limitations on Collection
Missouri has a 10-year collection period for state tax debts from the date of assessment. Tax liens expire 10 years after filing unless refiled during that period. The state may renew liens once for up to 20 years of total collection authority.
Frequently Asked Questions
Does an enforcement notice mean the state will immediately take my paycheck or bank account?
An enforcement notice indicates the state will pursue collection, but it does not automatically trigger wage garnishment or bank levy that same day. Contacting the Department promptly can often prevent or delay collection action.
Can I dispute the amount owed if I believe it is wrong?
You can request clarification and explain any errors you believe exist. The Department reviews disputes, but the burden of proof varies depending on whether you have documentation supporting your position.
What if I cannot pay the full amount right now?
The Department offers payment plans for tax debts. Contact the Missouri Department of
Revenue to inquire about installment agreement options that allow you to resolve the debt over time rather than facing immediate collection action.
Will my professional license be suspended?
Under Missouri law, professional licenses will be suspended if you fail to pay state taxes or file state tax returns and do not resolve the delinquency within 90 days of being notified by the
Department.
Can the Department intercept my federal income tax refund to apply to my
Missouri tax debt?
Yes, the Department and the Internal Revenue Service communicate with each other to ensure that neither agency is refunding tax revenue to an individual while that individual owes tax to the
other agency. Your federal income tax refund may be intercepted and applied to the Missouri debt.
If I move out of state, can the Department still enforce collection?
Yes, states have broad tools to enforce tax collection, including coordinating with other states and pursuing collection regardless of where you reside. Moving does not eliminate a Missouri tax obligation.
