This bill rewrites how Idaho parcels out highway-related revenue. It replaces the prior phased apportionment schedule with a straight 40% allocation to local governments and 60% to the state highway account, standardizes remittance timing, and updates language about investment earnings.
It also amends the gasoline and special-fuels distribution statutes to increase the annual transfer to the local bridge inspection account from $175,000 to $300,000 and to specify how the 7¢ portion of certain 32¢ fuel-tax increments is split between state and local highway accounts.
Why it matters: the measure locks in a permanent funding geometry that changes forecasting and budget planning for counties, cities and the Idaho Transportation Department (ITD). The adjustments to the per-gallon tax carve-outs and the boosted bridge-inspection line will alter revenue flows for local infrastructure maintenance and for other small dedicated accounts that depend on the same fuel-tax pool.
At a Glance
What It Does
The bill amends Idaho Code to: (1) set the Highway Distribution Account apportionment at 40% to local units and 60% to the state highway account; (2) raise the annual allocation to the local bridge inspection account from $175,000 to $300,000; and (3) codify the distribution of the residual 7¢ (of a 32¢ increment) so that it is split 60/40 between the state highway account and local distributions.
Who It Affects
Directly affects the Idaho Transportation Department, county and city road budgets, the state highway account, the local bridge inspection fund, and the State Tax Commission’s fuel-tax accounting. Law-enforcement accounts and small dedicated recreation/park accounts that receive fractions of fuel-tax revenue will see the mechanical effects of the reallocated cents.
Why It Matters
A permanent 40/60 split removes the previous multi-year phase-in and gives predictable shares to state and local governments — changing near-term budgeting for maintenance and capital projects. The bridge inspection increase and the clarified treatment of a 7¢ tax increment reallocate marginal dollars among competing transportation priorities, which matters for project timing and maintenance backlogs.

What This Bill Actually Does
The bill simplifies and stabilizes how Idaho divides up highway-related revenue. Instead of a graduated schedule that moved local and state shares each year, the statute now prescribes a permanent allocation: 40% of the Highway Distribution Account goes to local units of government under section 40-709, and 60% goes to the state highway account under section 40-702.
The state controller must continue to remit local apportionments quarterly on a fixed calendar, and the law keeps existing rules about investing idle highway moneys and returning interest to the originating accounts.
On the fuel-tax side, the bill increases the fixed annual transfer into the local bridge inspection account from $175,000 to $300,000, providing more dedicated funds for bridge inspections. It also makes explicit how a specific per-gallon increment — the ‘‘remaining 7¢ of every 32¢’’ referenced in current law — is to be split: 60% to the state highway account and 40% to local distributions under section 40-709.
The same clarification applies to both gasoline and certain special fuels, harmonizing treatment across chapters 63-2412 and 63-2418.Operationally, the Tax Commission retains the authority to withhold its actual collection costs (subject to appropriation limits) and to route refund obligations through the state refund account as before; the bill preserves that structure while making several technical edits. The act takes effect July 1, 2026, under an emergency clause so agencies and local governments can plan for the new permanent formula in the next fiscal year.
The Five Things You Need to Know
Section 40-701 establishes a permanent 40% allocation of the Highway Distribution Account to local units of government and 60% to the state highway account (replacing the prior phased percentages).
Section 63-2412 increases the annual transfer to the local bridge inspection account from $175,000 to $300,000 and directs that amount be distributed early in the fiscal year.
The statutes (63-2412 and 63-2418) specify that for certain taxed fuel increments, 25¢ of every 32¢ continues to be treated under existing distributions while the remaining 7¢ is explicitly split 60% to the state highway account and 40% to local distributions under section 40-709.
The bill preserves the Tax Commission’s ability to retain actual collection and enforcement costs (capped by legislative appropriation) and to route refunds through the state refund account; any unencumbered excess collection-cost balance is returned into the distribution pool.
The act declares an emergency and becomes effective July 1, 2026, making the new apportionment rules operative at the start of the next fiscal year.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Fixes apportionment at 40% local / 60% state and cleans up remittance rules
This section replaces the multi-year, incremental apportionment schedule with a single permanent split: 40% to local governments via section 40-709 and 60% to the state highway account via section 40-702. It also standardizes the controller’s remittance obligations (quarterly payments to local governments and periodic transfers to the state account as funds become available). Practically, the change removes staged increases that previously adjusted shares over several fiscal years and creates a stable, predictable formula for budgeters on both sides of the ledger.
Raises local bridge inspection funding and clarifies fuel-tax carve-outs
This amendment increases the fixed annual distribution to the local bridge inspection account from $175,000 to $300,000 and moves that transfer to occur “as soon as possible after the beginning of each fiscal year.” More substantively, the section clarifies how a fractional portion of per-gallon taxes (the 7¢ remainder when a 32¢ increment is parsed) is handled: the bill directs that 7¢ to be apportioned 60% to the state highway account and 40% to local distributions under 40-709. That reallocation tightens accounting rules that previously left room for uneven interpretation across fuel categories.
Harmonizes special-fuels distribution with gasoline rules
Parallel language in the special-fuels distribution statute mirrors the gasoline changes: collection costs and refunds remain prioritized, 7% continues to flow to the state highway account, and the balance goes to the Highway Distribution Account. For special fuels taxed under certain sections, the same 25¢/7¢ parsing applies and the bill directs the 7¢ remainder to a 60/40 state/local split, bringing consistency between gasoline and special-fuel accounting and reducing cross-program discrepancies.
Immediate fiscal-year implementation
The legislature declares an emergency and makes the act effective July 1, 2026. That timing aligns the new apportionment and bridge-inspection transfer with fiscal-year budgeting and requires state and local agencies to incorporate the new permanent split in their FY2027 planning.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- City and county road programs — Receive a fixed 40% share of the Highway Distribution Account, improving revenue predictability for maintenance and local capital projects and benefiting budgeting for pavement and bridge work.
- Local bridge inspection fund administrators and counties — The $300,000 annual transfer increases resources dedicated to bridge inspection work, which helps meet inspection frequency and safety compliance requirements without reallocating local general funds.
- Idaho Transportation Department (ITD) and state highway program — The state highway account receives a permanent 60% share, stabilizing state-level capital and maintenance planning and reducing uncertainty from prior phased schedules.
- Park and recreation accounts that receive small fractional allocations — The bill leaves in place the layered fractional distributions (waterways, off-road vehicle accounts, park capital improvement), preserving those revenue streams though their relative share may shift slightly as other allocations change.
Who Bears the Cost
- Law enforcement account previously funded from the highway distribution phasing — The statute phases its share down to zero; agencies that had relied on that revenue must replace it from other sources or absorb cuts.
- Localities facing fixed shares but increased obligations — Cities and counties that expected larger phased increases under the prior schedule may see less relative growth in future years and must adjust capital plans accordingly.
- Entities funded from the residual highway distribution balance — Increasing the bridge-inspection transfer and formalizing the 7¢ split reallocates marginal funds within the same pool, which can reduce discretionary availability for other projects or subaccounts.
Key Issues
The Core Tension
The central dilemma is predictability versus flexibility: the bill locks in fixed shares and a clearer cents-level accounting to give state and local governments reliable revenue forecasts, but in doing so it reduces the state’s ability to reassign those marginal fuel-tax dollars for emerging priorities (law enforcement, EV charging, or emergency needs) without further legislative change.
Two practical tensions will drive implementation headaches. First, converting a phased schedule into a fixed 40/60 split improves predictability but removes an intended glide-path for some accounts (notably the law enforcement account, which phases down).
That means agencies which had factored transient higher shares into multi-year plans must now rework budgets; the statutory language does not provide transition grants or mitigation for entities that budgeted against the old schedule.
Second, the bill’s carving of cents (25¢ vs 7¢ of a 32¢ increment) and the decision to split the 7¢ 60/40 between state and local accounts tidy up one ambiguity but create bookkeeping complexity. The Tax Commission and ITD will need to update collection and allocation systems to segregate those precise cents across gasoline and special-fuel receipts, and smaller dedicated recipients (parks, waterways, off-road accounts) will see their receipts fluctuate based on how residual balances now reconcile.
The statute preserves the Commission’s retention of collection costs (capped by appropriation), but it leaves some operational questions unresolved: for example, whether prior-year unencumbered balances in subaccounts used for administrative costs will be swept differently under the new apportionment, and how quarterly remittances align with cash-flow needs for large capital projects.
Finally, the bill strengthens the allocation rules at the cost of flexibility. Once codified, the rigid percentages limit the legislature’s ability to re-target fuel-tax revenue without another statute change, which may be desirable for predictability but could hamper responses to future fiscal shocks or shifting priorities such as accelerating electric-vehicle infrastructure investments.
