PUBLISHER’S NOTE: The secretary of state has determined that

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) In general, fuel used to operate public mass transportation
services is not subject to Missouri motor fuel tax. Fuel that is
not subject to Missouri motor fuel tax is subject to Missouri
state and local sales tax, unless otherwise exempted under
Chapter 144, RSMo.
(2) Basic Application.
(A) Operators of public mass transportation services who
purchase fuel and paid the Missouri motor fuel tax may
obtain a refund of the tax. The operator of the public mass
transportation service must certify to the department, on a
Form 5141 Public Mass Transportation Operator Exemption
Certificate, that the motor fuel will be used exclusively in the
operation of the mass transportation service.
1. The operator must submit the claim on a Form 4923
Non-Highway Use Motor Fuel Refund Claim within one (1) year
of the date of purchase or April 15 of the year following the
purchase, whichever is later.
2. The refund will equal the motor fuel tax, less all
applicable state and local sales taxes unless the entity is
otherwise exempt from Missouri sales tax.
(B) Ultimate vendors may make bulk sales of motor fuel to the
exempt public mass transportation service without collecting
the state motor fuel tax. The ultimate vendor that purchased
the motor fuel and paid the Missouri motor fuel tax may obtain
a refund if the ultimate vendor sold the motor fuel without
charging the Missouri motor fuel tax.
1. Operators must furnish the ultimate vendor a Form 5141
Public Mass Transportation Operator Exemption Certificate in
order to purchase the motor fuel without being charged the
Missouri motor fuel tax.
2. Any ultimate vendor who is a retailer, and not licensed
as a supplier or distributor, must submit the claim on a Form
4923 Non-Highway Use Motor Fuel Refund Claim within two (2)
years of the date of purchase.
3. If the ultimate vendor is licensed as a Missouri supplier
or distributor, the claim for refund must be submitted on a
Form 4923 Non-Highway Use Motor Fuel Refund Claim and
must be filed within three (3) years of the date of purchase.
4. The ultimate vendor must collect and remit to the
department any applicable state and local sales taxes at the
rate in effect at the vendor’s place of business.
(3) Examples.
(A) A public mass transportation service operator has vehicles
that operate on gasoline or gasohol. The operator goes to the
pump to fuel its vehicles. The operator will purchase the
gasoline or gasohol subject to all taxes and may apply for a
refund of the state motor fuel tax.
(B) A public mass transportation service operator has vehicles
that operate on diesel fuel. The operator may purchase clear
diesel fuel subject to the state motor fuel tax and apply for a
refund or if allowed under federal law, it may purchase dyed
diesel fuel, which is exempt from state and federal fuel tax. It is
required to complete and provide the ultimate vendor with an
exemption certificate prior to filling any vehicles or ordering
any dyed diesel fuel.
(C) A public mass transportation service operator has bulk
storage facilities for the motor fuel used to fuel its vehicles.
The ultimate vendor who delivers the motor fuel may sell the
product without charging the motor fuel tax. The ultimate
vendor would charge any applicable sales tax unless the
operator is exempt from sales tax under state law. The ultimate
vendor would then apply for a refund of the motor fuel tax it
paid on the motor fuel but did not collect from the operator.
(D) A public mass transportation service operator has
vehicles that operate on diesel fuel and meet the exemption
requirements under federal law. Its routes include states other
than Missouri, and the other state does not allow the use of
dyed diesel fuel on public roadways. Even though Missouri
and the federal government would allow the use of dyed diesel
fuel, the operator must purchase and use clear fuel in the
vehicles that cross into the neighboring state.
