Bill Summary · SB 26

Legislative bill overview

SB 26 allows Montana legislators to receive mileage reimbursement at the current IRS standard mileage rate rather than a fixed state rate. The bill has already been signed into law as of April 3, 2025, and establishes that lawmakers can claim reimbursement based on actual miles traveled for legislative business using the federally-determined rate.

Why is this important

Mileage reimbursement rates directly affect the out-of-pocket costs legislators bear when traveling to perform their duties, particularly in rural states like Montana where legislative districts can be geographically large. Using the IRS rate creates an objective, automatically-adjusting standard rather than requiring legislative action each time reimbursement rates need updating, though it also means rates may shift annually based on federal determinations.

Potential points of contention

  • Fiscal impact: Tying reimbursement to IRS rates (currently 67 cents/mile for 2024) may increase state expenditures if the federal rate exceeds Montana's previous fixed rate, potentially raising legislative operating costs unpredictably
  • Equity concerns: Legislators from remote districts would receive substantially more reimbursement than urban legislators for the same legislative duties, potentially creating disparate compensation based on geography
  • Precedent for federal alignment: Using IRS standards outsources rate-setting decisions to federal government, removing direct state legislative control over compensation spending
