Missouri State Tax Appeal

Petition to the Administrative Hearing Commission (state taxes) or Complaint to the State Tax Commission (property tax)

IMPORTANT — READ FIRST: There Is No "Missouri Tax Court"

Missouri does not have a single tax court or "tax tribunal." Which forum
hears your appeal — and the deadline to reach it — depends entirely on the type
of tax
:

  • Taxes administered by the Missouri Department of Revenue (individual income
    tax, corporate income/franchise tax, sales and use tax, withholding, fuel,
    cigarette, financial-institutions tax, etc.) are appealed to the Administrative
    Hearing Commission (AHC)
    — an independent adjudicative body — under Mo. Rev.
    Stat. § 621.050
    . Use PART A.

  • Locally assessed real and tangible personal property tax is appealed first to
    the county Board of Equalization (BOE), then to the Missouri State Tax
    Commission (STC)
    under Mo. Rev. Stat. § 138.430. Use PART B. (Exemption
    and taxable-situs disputes go instead to the circuit court — see the note in
    PART B.)

Deadlines are jurisdictional. Using the wrong forum, or missing the deadline,
forfeits the appeal.
The AHC and the courts have repeatedly dismissed late tax
appeals for lack of authority (e.g., New Garden Restaurant, Inc. v. Dir. of
Revenue
, 471 S.W.3d 715 (Mo. banc 2015)). Calculate every deadline from the date
the decision was mailed or delivered, whichever is earlier.

No automatic collection stay. Filing an appeal does not, by itself, stop
collection. To preserve a refund of a disputed tax you generally must pay
under protest
— for state taxes at the Department level, and for property tax
under Mo. Rev. Stat. § 139.031 (which impounds the disputed taxes during the
appeal). Do not advise a client that an appeal alone halts collection.

PART A — APPEAL TO THE ADMINISTRATIVE HEARING COMMISSION (STATE TAXES)

BEFORE THE ADMINISTRATIVE HEARING COMMISSION OF THE STATE OF MISSOURI

Caption
[TAXPAYER LEGAL NAME], Petitioner,
v.
DIRECTOR OF REVENUE, STATE OF MISSOURI, Respondent.
PETITION FOR REVIEW
Case No. [____] (assigned by the Commission)

A-1. Nature of the Appeal

Petitioner [TAXPAYER LEGAL NAME] appeals to the Administrative Hearing
Commission, under Mo. Rev. Stat. § 621.050, from the final decision, order, or
assessment of the Director of Revenue dated [DATE OF DECISION], a copy of
which is attached as Exhibit A. The decision was ☐ mailed ☐ delivered to
Petitioner on [DATE]. This Petition is filed within:

  • thirty (30) days of that date (income, corporate, withholding, and other
    taxes — § 621.050.1); or

  • sixty (60) days of that date (sales or use tax under Chapter 144 —
    §§ 144.261, 144.240).

A-2. Parties

Petitioner is [TAXPAYER LEGAL NAME], a
[STATE OF FORMATION] [ENTITY TYPE / INDIVIDUAL], Missouri Tax ID / FEIN
(last 4) [____], mailing address [ADDRESS]. Petitioner's authorized
representative is [NAME, MO BAR NO. IF ATTORNEY, FIRM, ADDRESS, PHONE, EMAIL].

Respondent is the Director of Revenue, whose decision is the subject of this
appeal.

A-3. The Assessment or Decision Being Contested

notices and correspondence. Attach supporting schedules as exhibits.]

  1. [____]
  2. [____]
  3. [____]

A-5. Issues and Grounds for Relief

Petitioner contends the Director erred as follows:

  1. [Issue 1] — [e.g., income was not Missouri-source / the transaction is exempt
    under Mo. Rev. Stat. § [____] / the correct apportionment factor is [____]].

  2. [Issue 2] — [e.g., a claimed deduction, credit, or exemption was improperly
    disallowed].

  3. [Issue 3] — [e.g., penalties and interest were improperly imposed; reasonable
    cause exists under [____]].

A-6. Burden of Proof

Petitioner acknowledges that under Mo. Rev. Stat. § 621.050.2 the burden of

(1) fraud with intent to evade tax, (2) liability as a transferee, and (3) any
increase in deficiency first asserted after the notice of deficiency was mailed and
a protest filed (unless the increase results from a federal change). Sales-tax
exemption may be proved under the applicable rules of evidence (§ 621.050.2).

  1. Find that the correct amount of tax due for the period(s) at issue is
    $[CORRECTED AMOUNT] (or such other amount as the Commission determines);

  2. Cancel or reduce the assessment and abate related penalties and interest to the
    extent the underlying tax is abated;

  3. Order the refund of any amount wrongfully collected or erroneously paid, with
    interest at six percent per annum
    where allowed by § 621.050.2 (sales tax paid
    under protest is held under § 144.700); and

  4. Grant such further relief as is just.

A-8. Procedure

This proceeding is governed by the contested-case provisions of the Missouri
Administrative Procedure Act, Chapter 536
(§ 621.050.2). The Commission maintains

review under § 621.189.

Exhibit A). This Complaint is filed with the State Tax Commission by
September 30, [YEAR] or within 30 days of the BOE decision, whichever is
later, as required by Mo. Rev. Stat. § 138.430.1 and 12 CSR 30-3.010.

B-4. Grounds for the Appeal (§ 138.430.1)

Complainant appeals on the following ground(s):

  • Overvaluation — the assessed value exceeds true value in money (fair market
    value) as of January 1 of the assessment year.

  • Discrimination — the property is assessed at a higher ratio of market value
    than other comparable property in the county.

  • Misclassification — the property is placed in the wrong subclass
    (residential / agricultural / commercial).

  • Incorrect method or formula used to determine value.

  • ☐ Other: [____].

B-5. Statement of Facts and Evidence

[State the facts supporting the claimed value: recent arm's-length sale price, a
certified appraisal, comparable sales, income and expense statements (for
income-producing property), cost of needed repairs, or evidence of the assessment
ratio applied to comparable property. Do NOT attach evidence to the Complaint
itself; the Commission will set a schedule for exchanging evidence.]

  1. [____]
  2. [____]
  3. [____]

assessment or valuation shown to be unlawful, unfair, improper, arbitrary, or
capricious
(§ 138.430.1), reduce the assessed value to $[____], reclassify the
property if applicable, and order any resulting refund or credit. Where an assessor
has classified the property contrary to a determination of the Commission or a court,
Complainant requests costs of appeal and reasonable attorney's fees under
§ 138.430.6.

B-7. Payment of Taxes Under Protest

☐ Complainant has paid / will pay the disputed taxes under protest so that they are
impounded during the appeal under Mo. Rev. Stat. § 139.031, preserving the right
to a refund if Complainant prevails.

About This Template

Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.

Important Notice

This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
