La. R.S. 47:337.77 — Refunds of overpayments authorized

A. For the purpose of this Section, "overpayment" means a payment of tax, penalty
or interest when none was due; the excess of the amount of tax, penalty or interest paid over
the amount due; or the payment of a penalty that is later waived or remitted by the collector,
provided that the power of the collector to refund overpayments shall be as prescribed and
limited in this Section.
B. The collector shall make a refund of each overpayment where it is determined
that:
(1) The tax was overpaid because of an error on the part of the taxpayer in
mathematical computation on the face of the return or on any of the supporting documents.
(2) The tax was overpaid because of a construction of the law on the part of the
taxpayer contrary to the collector's construction of the law at the time of payment.
(3) The overpayment was the result of an error, omission, or a mistake of fact of
consequence to the determination of the tax liability, whether on the part of the taxpayer or
the collector.
(4) The overpayment resulted from a change made by the collector in an assessment,
notice, or billing issued under the provisions of this Chapter.
(5) The overpayment resulted from a subsequent determination that the taxpayer was
entitled to pay a tax at a reduced tax rate.
(6) The overpayment was the result of a payment that exceeded either the amount
shown on the face of the return or voucher, or which would have been shown on the face of
the return or voucher if a return or voucher were required.
C. Notwithstanding the provisions of Subsection B of this Section, where it is
determined that there is clear and convincing evidence that an overpayment has been made,
the collector shall make a refund, subject to conditions or limitations provided by this
Chapter.
D.(1) Such refunds shall be made out of any current collections of the particular tax
which was overpaid.
(2) If a taxpayer has overpaid a particular tax for more than one taxable year and
seeks a refund of the total amount, the collector may issue the refund incrementally. The
number of increments shall not exceed the total number of years the tax was overpaid.
E. The collector may recover any refunded amount determined not to be an
overpayment through any collection remedy authorized by R.S. 47: 337.45 within two years
from December thirty-first of the year in which the refund was paid. Any refunded amount
determined not to be an overpayment shall bear interest at the rate provided for in this
Chapter, which shall be computed from the date the refund was issued to the date payment
is received by the collector.
F. This Section shall not be construed to authorize any refund of tax overpaid
through a mistake of law arising from the misinterpretation by the collector of the provisions
of any law or of any rules and regulations. In the event a taxpayer believes that the collector
has misinterpreted the law or rules and regulations contrary therewith, his remedy is by
payment under protest and suit to recover or petition to the Board of Tax Appeals, as
provided by law.
G. A claim for a refund or credit in a properly addressed envelope with sufficient
postage delivered by the United States Postal Service is deemed filed by the taxpayer and
received by the collector on the date postmarked by the United States Postal Service.
Additionally, a claim for refund or credit is deemed filed by the taxpayer and received by the
collector through any means provided for by any regulation promulgated pursuant to R.S.
47:337.97 through 337.100.
H.(1) A refund may be claimed pursuant to the provisions of this Section, subject to
the other conditions or limitations of this Chapter, on an amount paid on an otherwise final
assessment.
(2) The provisions of this Subsection shall not apply if the assessment became final
following an appeal of the assessment to the Board of Tax Appeals, or if an assessment
became final pursuant to a judgment in an action brought pursuant to R.S. 47:337.63 or
337.64.
(3) The provisions of this Subsection shall apply only if the taxpayer or dealer
establishes that it did not receive the assessment prior to the deadline for appealing that
assessment, and the collector did not comply with the provisions of R.S. 47:337.51(D).
