BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MONTANA:
Section 1. Section 39-71-117, MCA, is amended to read:
"39-71-117.  (1) "Employer" means:
(a) the state and each county, city and county, city school district, and irrigation district; all other 
districts established by law; all public corporations and quasi-public corporations and public agencies; each 
person; each prime contractor; each firm, voluntary association, limited liability company, limited liability 
partnership, and private corporation, including any public service corporation and including an independent 
contractor who has a person in service under an appointment or contract of hire, expressed or implied, oral or 
written; and the legal representative of any deceased employer or the receiver or trustee of the deceased 
employer;
(b) any association, corporation, limited liability company, limited liability partnership, or 
organization that seeks permission and meets the requirements set by the department by rule for a group of 
individual employers to operate as self-insured under plan No. 1 of this chapter;
(c) any nonprofit association, limited liability company, limited liability partnership, or corporation or 
other entity funded in whole or in part by federal, state, or local government funds that places community

state, or local government entities;

receiving remuneration from nonmembers for:
(i) manufacturing or construction activities conducted by its members on or off the property owned 
or leased by the religious corporation, religious organization, or religious trust; or
(ii) agricultural labor and services performed off the property owned or leased by the religious 
corporation, religious organization, or religious trust; and
(e) an approved and authorized fiduciary, agent, or other person acting as fiscal agent under 
section 3504 of the Internal Revenue Code, 26 U.S.C. 3504, and 26 CFR 31.3504-1.
(2) A temporary service contractor is the employer of a temporary worker for premium and loss 
experience purposes.
(3) Except as provided in chapter 8 of this title, an employer defined in subsection (1) who uses the 
services of a worker furnished by another person, association, contractor, firm, limited liability company, limited 
liability partnership, or corporation, other than a temporary service contractor, is presumed to be the employer 
for workers' compensation premium and loss experience purposes for work performed by the worker. The 
presumption may be rebutted by substantial credible evidence of the following that :
(a) the person, association, contractor, firm, limited liability company, limited liability partnership, or 
corporation, other than a temporary service contractor, furnishing the services of a worker to another retains 
control over all aspects of the work performed by the worker, both at the inception of employment and during all 
phases of the work; and
(b) the person, association, contractor, firm, limited liability company, limited liability partnership, or 
corporation, other than a temporary service contractor, furnishing the services of a worker to another has 
obtained workers' compensation insurance for the worker in Montana both at the inception of employment and 
during all phases of the work performed.
(4) An interstate or intrastate common or contract motor carrier that maintains a place of business 
in this state and uses an employee or worker in this state is considered the employer of that employee, is liable 
for workers' compensation premiums, and is subject to loss experience rating in this state unless:
(a) the worker in this state is certified as an independent contractor as provided in 39-71-417; or
(b) the person, association, contractor, firm, limited liability company, limited liability partnership, or 
corporation furnishing employees or workers in this state to a motor carrier has obtained Montana workers'  ****

ENROLLED BILL
compensation insurance on the employees or workers in Montana both at the inception of employment and 
during all phases of the work performed.
(5) The definition of "employer" in subsection (1)(d) is limited to implementing the administrative 
purposes of this chapter and may not be interpreted or construed to create an employment relationship in any 
other context.
(6) (a) A fiscal agent that qualifies under subsection (1)(e) and that is designated as a payor, using 
federal, state, or local government funds, under 26 CFR 31.3504-1 is considered to be the employer for the 
purposes of the Workers' Compensation Act of those workers for whom the fiscal agent is making payments.
(b) The client of the fiscal agent, despite exercising control over the hiring, scheduling, and 
direction of the work tasks performed by the worker, is not the employer of that worker for the purposes of the 
Workers' Compensation Act."
Section 2. Section 39-71-201, MCA, is amended to read:
"39-71-201.

provided for in Title 39, chapter 71, part 4, the subsequent injury fund provided for in 39-71-907, and the 
uninsured employers' fund provided for in 39-71-503. The department may use the workers' compensation 
administration fund to reimburse premiums for high-quality work-based learning programs, as provided in 39-
71-319. The department shall collect and deposit in the state treasury to the credit of the workers' 
compensation administration fund:

71-307, 39-71-315, 39-71-316, 39-71-401(6), 39-71-2204, 39-71-2205, and 39-71-2337; and
(b) all fees paid by an assessment on paid losses, plus administrative fines and interest provided

(2) For the purposes of this section, paid losses include the following benefits paid during the 
preceding calendar year for injuries covered by the Workers' Compensation Act without regard to the 
application of any deductible whether the employer or the insurer pays the losses: ****

(4) Each employer enrolled under compensation plan No. 1, compensation plan No. 2, or 
compensation plan No. 3, the state fund, shall pay its proportionate share determined by the paid losses in the 
preceding calendar year of all costs of administering and regulating the Workers' Compensation Act, with the 
exception of the certification of independent contractors provided for in Title 39, chapter 71, part 4, the 
subsequent injury fund provided for in 39-71-907, and the uninsured employers' fund provided for in 39-71-503. 
In addition, compensation plan No. 3, the state fund, shall pay a proportionate share of these costs based upon 
paid losses for claims arising before July 1, 1990.
(5) (a) Each employer enrolled under compensation plan No. 1 shall pay an assessment to fund 
administrative and regulatory costs. The assessment may be up to 4% of the paid losses paid in the preceding 
calendar year by or on behalf of the plan No. 1 employer. Any entity, other than the department, that assumes 
the obligations of an employer enrolled under compensation plan No. 1 is considered to be the employer for the 
purposes of this section.
(b) An employer formerly enrolled under compensation plan No. 1 shall pay an assessment to fund 
administrative and regulatory costs. The assessment may be up to 4% of the paid losses paid in the preceding 
calendar year by or on behalf of the employer for claims arising out of the time when the employer was enrolled 
under compensation plan No. 1.
(c) By April 30 of each year, the department shall notify employers described in subsections (5)(a) 
and (5)(b) of the percentage of the assessment that comprises the compensation plan No. 1 proportionate 
share of administrative and regulatory costs. The assessment provided for by this subsection (5) must be paid 
by the employer in:
(i) one installment due on July 1; or **** 
69th Legislature 2025 	HB 428
- 5 - Authorized Print Version – HB 428 
ENROLLED BILL
(ii) two equal installments due on July 1 and December 31 of each year.
(d) If an employer fails to timely pay to the department the assessment under this section, the 
department may impose on the employer an administrative fine of $500 plus interest on the delinquent amount 
at the annual interest rate of 12%. Administrative fines and interest must be deposited in the workers' 
compensation administration fund and may be used to pay the reimbursement of premiums required under 39-
71-319.
(6) (a) Compensation plan No. 3, the state fund, shall pay an assessment to fund administrative 
and regulatory costs attributable to claims arising before July 1, 1990. The assessment may be up to 4% of the 
paid losses paid in the preceding calendar year for claims arising before July 1, 1990. As required by 39-71-
2352, the state fund may not pass along to insured employers the cost of the assessment for administrative and 
regulatory costs that is attributable to claims arising before July 1, 1990.
(b) The assessment must be paid in:
(i) one installment due on July 1; or
(ii) two equal installments due on July 1 and December 31 of each year.
(c) If the state fund fails to timely pay to the department the assessment under this section, the 
department may impose on the state fund an administrative fine of $500 plus interest on the delinquent amount 
at the annual interest rate of 12%. Administrative fines and interest must be deposited in the workers' 
compensation administration fund.
(7) (a) Each employer insured under compensation plan No. 2 or plan No. 3, the state fund, shall 
pay a premium surcharge to fund administrative and regulatory costs. The premium surcharge must be 
collected by each plan No. 2 insurer and by plan No. 3, the state fund, from each employer that it insures. The 
premium surcharge must be stated as a separate cost on an insured employer's policy or on a separate 
document submitted to the insured employer and must be identified as "workers' compensation regulatory 
assessment surcharge". The premium surcharge must be excluded from the definition of premiums for all 
purposes, including computation of insurance producers' commissions or premium taxes. However, an insurer 
may cancel a workers' compensation policy for nonpayment of the premium surcharge. When collected, 
assessments may not constitute an element of loss for the purpose of establishing rates for workers' 
compensation insurance but, for the purpose of collection, must be treated as a separate cost imposed upon  ****

ENROLLED BILL
insured employers.
(b) The amount to be funded by the premium surcharge may be up to 4% of the paid losses paid in 
the preceding calendar year by or on behalf of all plan No. 2 insurers and may be up to 4% of paid losses for 
claims arising on or after July 1, 1990, for plan No. 3, the state fund, plus or minus any adjustments as provided 
by subsection (7)(f). The amount to be funded must be divided by the total premium paid by all employers 
enrolled under compensation plan No. 2 or plan No. 3 during the preceding calendar year. A single premium 
surcharge rate, applicable to all employers enrolled in compensation plan No. 2 or plan No. 3, must be 
calculated annually by the department by not later than April 30. The resulting rate, expressed as a percentage, 
is levied against the premium paid by each employer enrolled under compensation plan No. 2 or plan No. 3 in 
the next fiscal year.
(c) On or before April 30 of each year, the department, in consultation with the advisory 
organization designated pursuant to 33-16-1023, shall notify plan No. 2 insurers and plan No. 3, the state fund, 
of the premium surcharge percentage to be effective for policies written or renewed annually on and after July 1 
of that year.
(d) The premium surcharge must be paid whenever the employer pays a premium to the insurer. 
Each insurer shall collect the premium surcharge levied against every employer that it insures. Each insurer 
shall pay to the department all money collected as a premium surcharge within 20 days of the end of the 
calendar quarter in which the money was collected. If an insurer fails to timely pay to the department the 
premium surcharge collected under this section, the department may impose on the insurer an administrative 
fine of $500 plus interest on the delinquent amount at the annual interest rate of 12%. Administrative fines and 
interest must be deposited in the workers' compensation administration fund and may be used to pay the 
reimbursement of premiums required under 39-71-319.
(e) If an employer fails to remit to an insurer the total amount due for the premium and premium 
surcharge, the amount received by the insurer must be applied to the premium surcharge first and the 
remaining amount applied to the premium due.
(f) The amount actually collected as a premium surcharge in a given year must be compared to 
the assessment on the paid losses paid in the preceding year. Any excess amount collected must be deducted 
from the amount to be collected as a premium surcharge in the following year. The amount collected that is less  **** 
69th Legislature 2025 	HB 428
- 7 - Authorized Print Version – HB 428 
ENROLLED BILL
than the assessed amount must be added to the amount to be collected as a premium surcharge in the 
following year.
(8) By July 1, an insurer under compensation plan No. 2 that paid benefits in the preceding 
calendar year but that will not collect any premium for coverage in the following fiscal year shall pay an 
assessment of up to 4% of paid losses paid in the preceding calendar year. The department shall determine 
and notify the insurer by April 30 of each year of the amount that is due by July 1.
(9) An employer that makes a first-time application for permission to enroll under compensation 
plan No. 1 shall pay an assessment of $500 within 15 days of being granted permission by the department to 
enroll under compensation plan No. 1.
(10) The department shall deposit all funds received pursuant to this section in the state treasury, as 
provided in this section.
(11) The administration fund must be debited with expenses incurred by the department in the 
general administration of the provisions of this chapter, including the salaries of its members, officers, and 
employees and the travel expenses of the members, officers, and employees, as provided for in 2-18-501 
through 2-18-503, incurred while on the business of the department either within or without the state. 
Reimbursement of premiums required under 39-71-319 by the workers' compensation administration fund also 
is a debit on the fund.
(12) Disbursements from the administration fund must be made after being approved by the 
department upon claim for disbursement.
(13) The department may assess and collect the workers' compensation regulatory assessment 
surcharge from uninsured employers, as defined in 39-71-501, that fail to properly comply with the coverage 
requirements of the Workers' Compensation Act. Any amounts collected by the department pursuant to this 
subsection must be deposited in the workers' compensation administration fund."

administration fund."
