Letter Rulings
PURPOSE: This rule establishes procedures for issuing letter
rulings pursuant to section 536.021.10, RSMo.
(1) Letter Rulings.
(A) The director or his/her duly authorized agent as authorized
under section 536.021.10, RSMo shall issue letter rulings subject
to the terms and conditions set forth in this rule.
(B) When an issue on which a letter ruling is requested
is clearly covered by a duly enacted statute, regulation,
administrative rule, or a well-established principle of
interpretation of the law, the director may decline to issue a
letter ruling or issue an information letter instead of a letter
ruling. An information letter is not a letter ruling and is
not binding on the department. An information letter calls
attention to a well-established principle or interpretation of
the law and is merely a response for informational purposes.
(2) A letter ruling request must be made on the form or in the
format specified by the director for letter ruling requests by
email to gco@dor.mo.gov or by the online submission of that
form through the director’s website. Alternatively, the letter
ruling request may be made in writing to: Director of Revenue,
PO Box 475, Jefferson City, MO 65105.
(3) A letter ruling request must specifically state—
(A) That a “letter ruling is requested pursuant to section
536.021.10, RSMo”;
(B) The applicant’s—
1. Name (the name of the person, partnership, corporation,
or entity to whom the facts presented in the request apply);
2. Address and phone number;
3. Social Security or federal identification number; and
4. Appropriate Department of Revenue license, registration,
or identification number, where applicable;
(C) The type of tax, fee, bond, registration, or license at issue;
(D) The issue(s) on which a letter ruling is requested, stated
clearly and concisely;
(E) A complete, clear, and concise statement of all relevant
facts on which the letter ruling is requested;
(F) The applicant’s desired result and the legal basis for
that result, including reference to the applicable statutes,
regulations, and case law;
(G) Whether the issue, as it regards the applicant, is presently
under investigation or audit by the Department of Revenue.
The term investigation or audit includes but is not limited
to a notice of adjustment, notice of deficiency, assessment,
notice of loss of driving privilege, or notice of suspension or
revocation; and
(H) Whether the applicant is presently pursuing any protest,
litigation, or negotiation on the issue with the Department of
Revenue, as well as the name of any other person, partnership,
corporation, or entity whom the applicant or his/her duly
authorized representative knows is involved with the identical
issue pending before or with the Department of Revenue.
(4) The applicant may provide a draft letter ruling for the
department’s consideration.
(5) A request for a letter ruling must be signed by the applicant
or an authorized agent of the applicant. If the letter ruling
request is made on the form or in the format specified by the
director by email or by the online submission of that form
through the director’s website, a digital or electronic signature
by the applicant or authorized agent of the applicant satisfies
this requirement.
(6) The director or his/her duly authorized representative
may request additional information from the applicant as
deemed necessary to issue a letter ruling. Failure to provide
the requested information shall relieve the director of the
obligation to issue the letter ruling.
(7) A letter ruling shall have the following effect:
(A) The letter ruling shall apply only to the particular fact
situation stated in the letter ruling request;
(B) The letter ruling shall apply only to the applicant;
(C) The letter ruling shall bind the director, his/her duly
authorized agents, and their successors only prospectively;
(D) The letter ruling shall bind the director, his/her duly
authorized agents, and their successors as to transactions of
the applicant that occur within three (3) years after the date of
the issuance of the letter ruling; and
(E) An unfavorable letter ruling shall not bind the applicant
and shall not be appealable to any forum.
(8) The letter ruling shall cease to be binding if—
(A) A pertinent change is made in the applicable law by the
General Assembly;
(B) A pertinent change is made in the department’s
regulations;
(C) A pertinent change in the interpretation of the law is
made by a court of law or by an administrative tribunal; or
(D) The actual facts are determined to be materially different
from the facts set out in the applicant’s letter ruling request.
(9) The director will respond to letter ruling requests within
sixty (60) days of the date of receipt of a complete request.
(10) The director may refuse to issue a letter ruling for good
cause. The director, in a letter, must indicate the specific
reasons for refusing to issue the letter ruling. Good cause
includes but is not limited to the following:
(A) The request does not substantially comply with the
information required by this regulation;
(B) The request involves hypothetical situations or alternative
plans;
(C) The applicant requests the director to determine whether
a statute is constitutional under the Missouri Constitution or the
United States Constitution;
(D) The facts or issue(s) presented in the request are unclear,
overbroad, insufficient, or otherwise inappropriate as a basis
upon which to issue the letter ruling;
(E) The issue about which the letter ruling is requested is
primarily one of fact;
(F) The issue is presently being considered in a rulemaking
procedure, contested case, or other agency or judicial
proceeding that may definitively resolve the issue;
(G) The issue cannot be reasonably resolved prior to the
issuance of regulations;
(H) The applicant is under investigation or audit relating to
that issue, or the issue is the subject of investigation, audit,
administrative proceeding, or litigation;
(I) The issue relates to the application of the law to members
of a business, trade, professional or industrial association, or to
other similar group(s); and
(J) The applicant is not identified or is anonymous.
(11) A letter ruling shall include:
(A) A statement that: “This is a letter ruling issued by the
director pursuant to section 536.021.10, RSMo;” and
(B) The signature of the director or any person duly authorized
to issue letter rulings on his/her behalf.
(12) The applicant may withdraw the request for a letter ruling,
in writing or by email, prior to the issuance of the letter ruling.
