Wagering Tax
PURPOSE: This rule establishes standards for the wagering tax.
(1) For the purposes of this rule, “wagering tax” means the tax
assessment due pursuant to Article III, Section 39(g), of the
Missouri Constitution. Each Retail and Mobile licensee is subject
to a tax liability assessment. Wagering tax shall be calculated
on a cash basis, meaning wagers shall be reported when
received by the licensee and deductions for winning wagers
shall only be reported when the patron has been paid or when
funds have been remitted to the Gaming Commission Fund in
accordance with the rules.
(2) Wagering taxes shall be paid via an electronic funds transfer system employing an Automated Clearing House Debit
method (ACH-Debit). Each Retail and Mobile licensee shall
maintain an account with sufficient funds to pay, in a timely
fashion, all tax liabilities due. The account shall be maintained
at a financial institution capable of making electronic funds
transfer payments to the state.
(3) The commission will provide a computer program for the
input of tax calculation information for the monthly sports
wagering tax remittal. Each Retail and Mobile licensee shall
enter the required data for the calculation of the tax liability
for each monthly reporting period by the due date.
(4) The monthly sports wagering tax remittal shall be submitted
to the commission no later than 12:00 noon Central time on
the due date. Wagering tax payments shall be transferred
electronically to the commission’s designated financial
institution no later than 12:00 noon Central time on the due
date. For purposes of tax schedules and tax payments, the
due date shall be the fifteenth day of the month following
the calendar month in which the adjusted gross revenue was
received and the wagering tax obligation was accrued. The
tax payment shall be remitted by the due date regardless of
whether or not the fifteenth day falls on a banking day.
(5) The wagering tax imposed on the Retail or Mobile licensee
shall be based on adjusted gross revenue from sports wagering.
Adjusted gross revenue for a given month equals the total
value of all cash and cash equivalents received by the licensee
for sports wagers minus the total of—
(A) All cash and cash equivalents paid out as winnings to
sports wagering patrons;
(B) The actual cost paid by a licensee for anything of value
provided to and redeemed by patrons, including merchandise
or services distributed to sports wagering patrons to incentivize
sports wagering;
(C) Voided wagers;
(D) Cancelled wagers;
(E) The cost of free play or promotional credits provided to and
redeemed by the applicable licensee’s patrons, provided that
the aggregate amount of such cost of free play or promotional
credits that may be deducted under this subsection in any
calendar month shall not exceed twenty-five percent (25%)
of the total of all cash and cash equivalents received by the
applicable licensee for such calendar month;
(F) Any sums paid as a result of any federal tax, including
federal excise tax; and
(G) Uncollectible sports wagering receivables, not to exceed
two percent (2%) of the total of all sums, less the amount paid
out as winnings to sports wagering patrons.
(6) If the amount of adjusted gross revenue in a calendar
month is a negative number, the licensee shall remit no
sports wagering tax for that calendar month. Any negative
adjusted gross revenue shall be carried over and calculated
as a deduction in the subsequent calendar months until the
negative balance has been brought to zero.
(7) The sports wagering tax remittal shall include all information necessary for adjustments and reconciliation of tax
liability and shall be subject to audit by the commission.
Adjustments to previously reported tax information shall be
made by the licensee, except that no adjustment of twenty-five
thousand dollars ($25,000) or more shall be made to previously
reported adjusted gross revenue without the prior written approval of the commission.
