PUBLISHER’S NOTE: The secretary of state has determined that
publication of the entire text of the material that is incorporated
by reference as a portion of this rule would be unduly cumbersome
or expensive. This material as incorporated by reference in this
rule shall be maintained by the agency at its headquarters and
shall be made available to the public for inspection and copying
at no more than the actual cost of reproduction. This note applies
only to the reference material. The entire text of the rule is printed
here.
(1) If the taxpayer in good faith believes that they are not
subject to the sales tax under the Missouri sales tax act, they,
upon payment of the required amount of tax, and denoting the
payment as a protest payment when made, may file a protest
payment affidavit, in which they specifically shall set out why
they are protesting payment of the tax and give supporting
information. The protest claim shall be made by filing a
Form 163, Sales Tax Protest Payment Affidavit, under oath and
submitted within thirty (30) days after the protest payment.
Failure to denote the payment as made under protest, or to
make a protest claim within the time required, and under the
conditions specified will void the protest claim.
(2) If a protest payment is not made by the required due date,
interest and additions to tax should be included in the payment
to properly perfect the protest.
(3) Overpayments resulting from clerical, mathematical, or
similar errors should be recovered by following the refund
procedures outlined in section 144.695, RSMo. If any taxpayer,
in good faith, and for just cause, feels the imposition of
Missouri use tax has been improperly charged against them,
they, when making their payment, may denote the payment as
a protest payment, and execute a protest payment using a Sales
or Use Tax Protest affidavit, Form 163B, specifically stating the
grounds upon which the protest is being made. The claim must
be made under oath within thirty (30) days after payment. If
this procedure is not followed, all payments will be accepted
by the director as proper payments.
(4) A taxpayer filing a protest payment return must submit a
notarized protest payment affidavit with the return, reflecting
the specific amount of tax being paid under protest. Separate
checks need not be submitted for the state and local sales taxes
being protested.
(5) Form 163, Sales Tax Protest Payment Affidavit, and Form
163B, Sales or Use Tax Protest Affidavit, revised March 2020, are
incorporated by reference and are published by and can be
obtained from the Missouri Department of Revenue at www.
dor.mo.gov or at the Harry S Truman State Office Building, 301
W. High Street, Jefferson City, MO 65101. These forms do not
include any amendments, or additions since the revision dates
noted.
