  • File a Protest with the Department of Revenue.If you do not agree that you owe the amounts shown on this Assessment of Unpaid Withholding Tax, you may file a protest with the Department. Under Section 143.631, RSMo, a protest is a written statement that explains in detail the reasons you do not owe the amounts shown on the Assessment of Unpaid Withholding Tax. You should include copies of any documents that you would like the department to consider when reviewing your protest (e.g., tax returns or payroll ledgers).

You must file a protest within 60 days (150 days if you live outside the United States) after the date this Assessment of Unpaid Withholding Tax was mailed or the date it was delivered, whichever date is earlier. Mail your protest to:

Missouri Department of Revenue
PO Box 3375
Jefferson City, MO 65105-3375

Informal Hearing: You may request an informal hearing with the Department to explain the reasons for your protest. Request an informal review at the address listed at the top of the notice.

Granting Your Protest: If the Department agrees with your protest, the Department will adjust the amount shown on the Notice of Deficiency and notify you of the decision in writing.

Denying Your Protest: If the Department does not agree with your protest, the Department will notify you of the Department’s decision in writing. Under Section 143.651, RSMo, you may then file an appeal of that decision with the Missouri Administrative Hearing Commission. The Department will provide details of how to appeal its decision in the notification.

Pay Under Protest. If you file a protest, you may also pay all or any part of the amounts due under protest. (Section 143.631,RSMo) By paying under protest, you stop the accrual of additional interest on the amounts paid. If you file a valid protest, but do not pay the balance due, the collection process will be suspended but the interest will continue to accrue.

To pay under protest, you must:

  • Send a check or money order for the amount of the protest payment to the address listed on the Assessment of Unpaid Withholding Tax.
  • Write on the front of the check or money order that it is a protest payment.
  • Include with your payment and written protest a statement of the tax type, tax period(s), and the amount of tax, interest, penalties, and additions to tax to which the payment is to be applied.

Your payment under protest must be received by the Department of Revenue within 60 days (150 days if you live outside the United States) after the notice date shown on the Assessment of Unpaid Withholding Tax.

  • You will no longer have the legal right to appeal;
  • All tax, interest, penalties, and additions to tax, if any, will be payable in full;
  • A Certificate of Tax Lien may be filed with the Recorder of Deeds against any and all personal and real property owned by you. This will directly impact your credit rating and your ability to buy or sell real estate until your tax balance due is resolved;
  • A Certificate of Tax Lien may also be filed with the Clerk of the Circuit Court. This will have the full force and effect of a default judgment; and
  • If you also make retail sales, your sales tax license will be revoked and you will not be able to legally operate your business.

  • Provide documentation: If you disagree with the adjustment, you may file an amended Form 941 and submit copies of your payroll ledgers to support the withholding for that period.

Understanding Your Notice

Because prior notices have not resolved your delinquency, Missouri statute calls upon the Department to escalate collections. As a result, the Department may file a lien in any case in which it issued an assessment of tax, interest, addition to tax or penalty imposed under Sections 143.005 to 143.998 RSMo, and that assessment has become final.

A Notice of Tax Lien:

  • May be filed for record in the recorder's office of the county in which the person resides or owns property;
  • Attaches to real or personal property or interest in real or personal property owned by the person or acquired by the person after the filing of the certificate of lien;
  • May be filed with the circuit court and will have the effect of a default judgment. This allows the Department to collect on the judgment through garnishment, executions, and levies.
  • Will have negative impact on your credit rating. A lien may be listed on your credit report. Credit bureaus monitor public records for liens. The Department does not report lien information directly to the credit bureau agencies. However, the tax lien and the cancellation of the lien are considered public information once filed with the recorder of deeds or the circuit court. The Department does not govern the credit bureau agency’s policy regarding the length of time or the accuracy of the information they keep on a credit bureau report; and
  • Will prevent you from buying or selling real property (and potentially personal property, such as vehicles).

Resolving Your Notice

The Department may only issue a Certificate of Lien Release and Satisfaction if:

  • The debt is paid in full; or
  • You provide documentation showing you do not owe the debt.

Paying the Debt in Full: A taxpayer, power of attorney, financial institutions or title company may request for the amount needed to pay the lien off in full by reaching out to collections@dor.mo.gov to request a payoff that includes updated interest. A satisfaction will be issued within 45-60 days of the balance being resolved.

What about an Installment Agreement? If you cannot pay the balance off in full, you may set up a payment plan to take care of your debt with the Department. To request an installment agreement, access our website at http://dor.mo.gov/cacs/. A lien will not be released until the debt is paid in full.

Partial lien Release: There are situations where the Department’s lien may be released against one particular piece of property for less than full payment of the lien. The Department is not legally required to issue a partial lien release; however, some circumstances may be taken into consideration. You must complete the Partial Satisfaction and Discharge of Tax Lien (Form 5615) and send in along with a HUD I statement and the property description. Further documentation may be requested as needed. Based on the information submitted, the Department may require partial payment, full payment or no payment towards the tax lien to issue a partial release.

Understanding Your Notice

Unpaid taxes may be referred to a collection agency. In addition to recovering the tax debt, Missouri statutes allow a 100 percent civil penalty and criminal prosecution for willful attempts to evade the tax.
