As used in this chapter, unless the context and subject matter otherwise clearly require:
1. "Company" includes any individual, copartnership, business trust, corporation, limited
liability company, joint-stock company, or association.
2. "Gas company" means a company owning, holding, or operating under lease or
otherwise any property in this state for the purpose of furnishing gas, or distributing the
same, for public use, by means of pipelines.

otherwise any property in this state for the purpose of transporting crude oil, natural
gas, processed gas, manufactured gas, refined petroleum products, or coal and
related products for public use.

for the purpose of furnishing or distributing electric light, electric power, or steam heat
for public use.
5. "Transmission line" means a line to transmit electrical energy which operates at a
voltage of forty-one and six-tenths kilovolts or more but does not include a line owned

### § 57-06-03. Operative property defined.

The term "operative property" means any and all property that is not exempt under this
chapter by reason of an election filed under chapter 57-33.2 and which is reasonably necessary
for use by any company mentioned in section 57-06-02 exclusively in the operation and conduct
of the particular kind of business engaged in by it. Any such property held under a contract for
the purchase thereof must be considered for all purposes of taxation as the property of the
company holding the same. Any such property, real or personal, held by any company under a
rental lease must be assessed by the state board of equalization in the name of such company,
if an agreement in writing between the owner thereof and such company is filed with the tax
commissioner requesting that such leased property be so assessed. Whenever any property of
a public utility company required to be assessed by the state board of equalization under the
provisions of this chapter is used partly for operative purposes and partly for other purposes,
either by the company or by others, all such property that is not exempt under this chapter by
reason of an election filed under chapter 57-33.2 must be assessed by the state board of
equalization as operative property of the company. Notwithstanding any other provision of law,
all oil or gas pipeline property that is not exempt from ad valorem taxation is subject to
assessment by the state board of equalization under this chapter.

required under this chapter, shall set forth in detail property thus jointly owned so as to show
specifically what interest each joint owner has therein. Notice to any company having control,
supervision, and maintenance of such jointly owned property is notice to all companies
interested therein.

at the rate of three hundred dollars per mile [1.61 kilometers] or fraction thereof of the line
located in this state. The per mile tax imposed by this section applies to the transmission line
and its associated transmission substations and is subject to allocation among counties in the
proportion that the miles of that transmission line in the county bears to the miles of that
transmission line in the state.

amount of taxes that would have been assessed against pipeline facilities property exempted

### § 57-06-22. Enforcement of collection.

The property of a company assessed under the provisions of this chapter, for the purposes
of assessment and taxation and the collection of taxes, must be considered personal property.
The taxes assessed on such property are a perpetual paramount lien upon all the franchises
and property, both real and personal, of every kind and nature belonging to the company

assessed from and after the date upon which the assessment is made, and no sale or transfer
of such property, or of any part thereof, divests, or in any way affects, the lien for the taxes upon
such property. No company which has been assessed and taxed under the provisions of this
chapter is entitled to have a transfer of any of its said property by deed, bill of sale, or otherwise
entered, filed, or recorded upon the records of the office of the recorder, county treasurer, or
county auditor, unless all taxes then due against the said property first are paid and satisfied. All
laws not in conflict with the provisions of this chapter, relating to the enforcement of the payment
of delinquent personal property taxes, are applicable to all taxes levied on such property
pursuant to the provisions of this chapter, and when any taxes levied pursuant to the provisions
of this chapter become delinquent, the county treasurer charged with the duty of collecting such
delinquent taxes shall proceed to collect the same in the manner now provided by law for the
collection of delinquent personal property taxes. If collection is made by seizure and sale, the
sale must be at public auction held at the county courthouse.
### § 57-06-23. Deposit of revenue - Report to treasurer.

### § 57-06-24. Allocation - Continuing appropriation.

1. The electric generation, transmission, and distribution tax fund is appropriated as a
continuing appropriation to the state treasurer for allocation and distribution to counties
by April first of each year as provided in this section. The state treasurer shall make
the necessary allocations to the counties based on the report received from the tax
commissioner. The county auditors shall make the necessary allocations to the taxing
districts.
2. Revenue from the tax on transmission lines under section 57-06-17.3 must be
allocated among counties based on the mileage of transmission lines within each
county. Revenue received by a county under this subsection must be allocated
one-third to the county and two-thirds among the county and other taxing districts in
the county based on the mileage of that transmission line where that line is located
within each taxing district. Revenue from that portion of a transmission line located in
more than one taxing district must be allocated among those taxing districts in
proportion to the taxing district's most recent property tax mill rates that apply where
the transmission line is located.
### § 57-06-25. Delinquent taxes - Penalty.

Taxes under section 57-06-17.3 are due January first for the preceding taxable year and are
delinquent if not received by the commissioner by March first following the due date. If any
amount of tax imposed by this chapter is not paid on or before March first, or if upon an
additional audit additional tax is found to be due, there must be added to the tax due a penalty
at the rate of one percent of the tax due for each month or fraction of a month during the first
year during which the tax remains unpaid, computed from March first. Beginning on January first
of the year following the year in which the taxes become due and payable, simple interest at the
rate of twelve percent per annum upon the principal of the unpaid taxes must be charged until
the taxes and penalties are paid, with the interest charges to be prorated to the nearest full
month for a fractional year of delinquency.
