Understanding Your Notice

This notice is titled “Notice of Proposed Changes” because the Department made changes to your return. In this notice, the Department will show you how the calculations differ. These adjustments could be a simple calculation error. Likewise, it could be that the Department did not receive proper documentation to support a line item. This is the initial notice you will receive regarding an individual income tax adjustment. It is best to resolve it as soon as possible.

The following are common reasons for adjustments:

  • The Department received the return without necessary documentation attached (for example, all Form(s) W-2 and Form(s) 1099 were not included with the return). The notice will let you know the documentation you need to provide;
  • The amount of Missouri tax withheld claimed is not correct, usually because the withholding claimed on the return does not match the Form(s) W-2 and Form(s) 1099 or the Missouri Return claimed withholding from another state or city. Check your Form(s) W-2 and Form(s) 1099 to make certain the amount claimed matches the amount claimed on your Missouri tax return. If the amount does not match, the Department did not receive all Form(s) W-2 and Form(s) 1099;
  • The Department found calculation errors on the return. Check your return for calculation errors;
  • The amount of Federal tax withheld is claimed as a deduction. This is incorrect. Instead, the actual Federal tax liability should be claimed as a deduction. Review your return to make sure you are claiming the federal tax liability you calculated on your Federal return, rather than the Federal tax withheld from your Form(s) W-2;
  • The wrong filing status box is marked. The filing status for Missouri must match your filing status from your federal return;
  • Total number of dependents claimed is incorrect. You cannot claim yourself or your spouse as a dependent;
  • The amount of estimated tax payments claimed does not reflect the amount the Department has received;
  • Verification is needed to support figures claimed on an electronically filed return. The amount of income you claimed does not match information provided to the Department from independent sources or you claimed a loss on your return that you have not had in the past;
  • The adjustment can also be the result of information received from other agencies, such as the Internal Revenue Service (IRS), or failure to file a required return. For example, your employer reported income to the IRS but the income was not reported by you on your Missouri income tax return.  The IRS could also notify the Department of additional income discovered through a federal audit. If the IRS has reversed their audit based on information you provided them, that information may not have reached the Department.  You can submit a Federal Account Transcript so that we may review your account further.

Resolving Your Notice

  • Submit the documentation requested (Form(s) W-2 and Form(s) 1099, federal return or account transcript,) on the notice to resolve the proposed change(s);
  • If you agree with the change(s) the Department made and the result is a balance due, pay the balance in full. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing;
  • Submit a proposed installment agreement to pay the full amount within one year. To request an installment agreement, access our website at http://dor.mo.gov/cacs/.
  • If you agree with the change(s) the Department made and the result is a reduced refund, the Department will issue the refund accordingly; or
  • If you disagree with the change(s) the Department made and the result is a reduced refund, you may file a protest with the Department. If you wish to file a protest, you must do so within 60 days of the date of the notice. Please provide a basis for the protest and submit it to the Department at the address shown on the notice. The Department will review your return and notify you of their decision.

This notice reflects changes made to your return based on information available to the Department. This information may have been filed with your return, provided later by you or your tax preparer, or based on data from other sources such as the IRS.

Resolving Your Notice

  • Verify that the adjustment we made to the return is consistent with your records;
  • Submit any additional documentation (Form(s) W-2 and Form(s) 1099, Federal Return or Account Transcript, 1099s) you believe will result in further adjustment to your return;
  • If you agree with the change(s) the Department made and the result is a balance due, pay the balance in full. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing;
  • If you disagree with the change(s) the Department made and the result is a balance due, you may file a protest once you receive a Notice of Deficiency.  You will have 60 days to file a protest from the Notice of Deficiency date.
  • Submit a proposed installment agreement to pay the full amount within one year. To request an installment agreement, access our website at http://dor.mo.gov/cacs/.
  • If you agree with the change(s) the Department made and the result is a reduced refund, the Department will issue the refund accordingly; or
  • If you disagree with the change(s) the Department made and the result is a reduced refund, you may file a protest with the Department. The Department will issue the reduced refund. If you wish to file a protest regarding the portion of the refund that was not issued, you must do so within 60 days of the date of the notice. Please provide a basis for the protest and submit it to the Department at the address shown on the notice. The Department will review your return and notify you of their decision.

Understanding Your Notice

You received this notice because:

  • The Department received a return indicating a balance due.
  • The Department did not receive a payment in full.

Resolving Your Notice

You may resolve this notice by paying the balance in full. Paying the balance due before the due date will avoid additions and interest charges to your account. You can:

  • Pay the amount due. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing.
  • Submit a proposed installment agreement to pay the full amount within one year. To request an installment agreement, access our website at http://dor.mo.gov/cacs/.

If you do not pay in full:

  • You will be charged additions to tax and interest on any balance remaining after the due date until fully paid;
  • The Department will issue a notice of deficiency; and
  • Further collection actions will occur on the balance remaining, the additions to tax and the accumulated interest.

Understanding Your Notice

If you did not resolve the debt associated with the Notice of Proposed Changes, Notice of Adjustment, or a Notice of Balance Due, the Department will issue a Notice of Deficiency. This is a statutory notice that assesses the tax, interest, and additions owed to the Department. If this notice is not resolved, the Department will escalate collection efforts. This escalation may include referrals to collection agencies or prosecuting attorneys. Your federal income tax refund may also be intercepted and applied to the Missouri debt.

Resolving Your Notice

Under Missouri law, you have a right to either pay your tax delinquency or dispute the amount owed. It is critical that you take one of the following actions upon receipt of a Notice of Deficiency:

  • Pay the amount due. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing.
  • Submit a proposed installment agreement to pay the full amount within one year. To request an installment agreement, access our website at http://dor.mo.gov/cacs/
  • File a Protest with the Department of Revenue. If you do not agree that you owe the amounts shown on this Notice of Deficiency, 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 Notice of Deficiency. You should include copies of any supporting documentation that you would like the Department to consider when reviewing your protest (e.g., tax returns or W-2’s).

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

Missouri Department of Revenue
P.O. Box 385
Jefferson City, MO 65105-0385

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 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, the collection process will be suspended, but the interest will continue to accrue on the balance due.

To pay under protest:

  • Send a check or money order for the amount of the protest payment to the address listed on the Notice of Deficiency.
  • Write “Protest Payment” on the front of the check or money order.
  • 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) from the notice date shown on the Notice of Deficiency. The notice of deficiency is final after 60 days (150 days if you live outside the United States) and you can no longer protest. 

If you do not respond with one of the above options within 60 days of the notice date:

  • All tax, interest, penalties, and additions to tax, if any, will be payable in full;
  • You will no longer have the legal right to appeal;
  • 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 this is resolved; and
  • 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.

Understanding Your Notice

The Department and the IRS 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. This notice informs you that your federal income tax refund may be intercepted and applied to the Missouri debt.

Resolving Your Notice

To prevent an offset of your federal income tax refund, you may:

  • Pay the amount due. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing.
  • Submit a proposed installment agreement to pay the full amount within one year. To request an installment agreement, access our website at http://dor.mo.gov/cacs/.

    It is always best to resolve your balance due as quickly as possible to avoid an offset from your federal refund. Sometimes you may pay your balance due but the IRS has already intercepted your federal refund and is in the process of forwarding it to the Department. In these circumstances, the Department will refund any overpayment resulting from your payment or offset (there are exceptions if the taxpayer also owes other state agencies, such as Department of Social Services offsets).

Understanding Your Notice

This notice informs you that your Missouri income tax refund has been intercepted and applied to a debt that you owe to another state or federal agency. Examples of agencies that report outstanding debts to the Department are as follows:

  • Department of Social Services
  • Division of Employment Security
  • Missouri Department of Higher Education
  • Department of Mental Health
  • Office of State Public Defender
  • Department of Health
  • Office of State Court Administration
  • Internal Revenue Service (IRS)
  • State Universities and Community Colleges
  • Kansas Department of Revenue
  • Department of Corrections
  • Lottery
  • Housing Authority
  • Missouri Division of Motor Vehicle, Returned Checks
  • Driver’s License/Motor Vehicle Fraud

Resolving Your Notice

To prevent offsets of your Missouri refund, you must contact the Department or the agency that intercepted your refund and resolve the debt with them. If you do not resolve the debt, your future refunds may be offset.

If you are married filing jointly and your spouse has a debt with the Department or another agency, you may mark the non-obligated spouse box on your Missouri individual income tax return to prevent your portion of the refund from being intercepted. If you did not mark the non-obligated spouse box and your refund has been intercepted, you must contact the agency that intercepted your refund to dispute the offset. Debts owed to the Internal Revenue Service (IRS) are excluded from the non-obligated spouse apportionment.

It is always best to resolve your balance due as quickly as possible, in order to avoid an offset from your Missouri return. If you have paid your balance due, but your refund had already been intercepted, you must resolve the issue with the agency that intercepted your refund. That agency will be responsible for refunding any overpayment.

Understanding Your Notice

This notice outlines the amount you must pay the Department and is your last opportunity to resolve your account before the Department escalates collections.

Resolving Your Notice

You may:

  • Pay the debt in full. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing;
  • Submit a proposed installment agreement to pay the full amount within one year if you are unable to pay the full amount at this time. To request an installment agreement, access our website at http://dor.mo.gov/cacs/; or
  • Submit documentation to dispute your balance due. Examples of documentation could be proof of payment, an amended Missouri return, or proof of Missouri tax withheld to offset your tax liability.

If you do not take action, the Department will:

  • Issue a lien or administrative judgement;
  • Begin the garnishment process;
  • Refer your account to the county prosecutor’s office or a collection agency.

The Department prefers to resolve your account without utilizing these collections measures.

Understanding Your Notice

Because your delinquency has not been resolved, Missouri statute calls upon the Department to escalate collections. As a result, the Department may file a lien in any case in which you were issued an assessment (Notice of Deficiency) 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 when acquired by the person after the filing of the certificate of lien;
  • May be filed with the circuit court which 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.
  • Will prevent you from buying or selling real property (and potentially personal property, such as vehicles); and
  • Will be published on the Department’s web site.

Resolving Your Notice

The Department can 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: For immediate release after payment, you must pay the entire balance due by cashier's check or money order. If payment is made by any other method, the lien will release in 45 to 60 days. When a lien is cancelled, the Department sends the taxpayer a Notice of Full Satisfaction and Discharge of Tax Lien.
  • What about an Installment Agreement? If you cannot pay the balance off in full, you can 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 can 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 will 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

This notice is sent to notify you that the Department may take action to garnish your wages from your employer or funds from your bank account. The notice will list the periods owed. At this point, there is no active garnishment on your account, but action may be taken. Any unpaid amount you owe on your account will show on this letter. Once garnishment actions begin they can continue until you resolve the balance.

Resolving Your Notice

To avoid garnishment, you can:

  • Pay the debt in full. Send a check or money order, made payable to the Department of Revenue to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express. Call toll free (888) 296-6509. There will be a convenience fee charged to your account for processing;
  • Provide documentation showing you do not owe the debt; or
  • Contact the Department at the number provided on the notice to discuss options to avoid the garnishment.

Once a garnishment is active, a payment plan is not an option until the garnishment period has expired.

Note: A lien tied to the garnishment will only be released quickly if you pay in full by cashier’s check or money order.

Understanding Your Notice

Unpaid taxes may be referred to a collection agency or to a local Prosecuting Attorney. 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.

Resolving Your Account

Send a check or money order, made payable to the Department of Revenue, to the address listed on the notice. You can also pay the amount due online via electronic funds transfer from your bank account. The Department also accepts Mastercard, Visa, Discover, and American Express.
