Amends and adds to existing law to provide certain property tax exemptions for certain utilities and to provide for a tax on rate-regulated electric companies and gas companies.
Summary
House Bill 329 restructures how Idaho taxes certain utility property and utility sales. It repeals several existing provisions tied to the assessment and exemption of operating property for rate-regulated electric utilities and gas companies, then replaces them with a new framework that shifts these utilities away from county property tax assessment on specified operating property and toward statewide per-unit taxes. The bill also updates definitions and tax treatment for rate-regulated electric utility companies, rate-regulated affiliated gas companies, and rate-regulated gas companies, while preserving separate treatment for wind, solar, and geothermal producers.
The measure creates a new system under which the State Tax Commission calculates, bills, collects, and distributes kilowatt-hour and thermal energy taxes beginning in 2027, with county treasurers and county auditors then allocating the proceeds to taxing districts and urban renewal agencies based on specified proportions. It also adds a new exemption for electricity used to pump water for irrigation or drainage, allowing the kilowatt-hour tax to be reduced for that use and requiring utilities to credit or refund the exempt amount to qualifying consumers. The bill further directs utilities to include these taxes on customer billings and authorizes the Public Utilities Commission to adjust base tariff rates to account for property tax recovery already embedded in rates.
Impact
The bill would significantly alter Idaho Code provisions governing utility taxation by repealing sections related to assessment of operating property and certain exemptions, amending the operating-property assessment statute, and adding new sections that centralize tax calculation and distribution at the state level. It changes the tax base for rate-regulated electric and gas utilities from traditional property taxation on certain operating property to a kilowatt-hour tax and thermal energy tax, while preserving county-level assessment for property not subject to those taxes. Counties, taxing districts, and urban renewal agencies would still receive revenue, but through a state-administered apportionment process tied to 2025 property tax distributions and later statutory formulas. Irrigation users would gain a specific exemption for electricity used in pumping water, and utilities would be responsible for administering the related credits or refunds.
Sentiment
The voting history suggests the bill had broad legislative support, passing the House 61-7 and the Senate 31-3. That margin indicates general approval of the tax restructuring and the shift to a statewide collection and distribution model. No committee transcript was provided, so there is no recorded discussion here showing detailed support or opposition arguments, but the votes indicate the bill was not especially controversial overall.
Contention
The main points of contention likely center on the bill’s redistribution of utility tax administration and revenue, especially the move away from county-assessed operating property toward state-collected per-unit taxes. Counties, taxing districts, and urban renewal agencies may be concerned about how the new apportionment formulas, the 2025 baseline, and restrictions on new taxing districts affect future revenue. Another likely issue is the irrigation exemption, which benefits agricultural users but requires utilities to track usage and issue credits or direct payments, creating administrative complexity. The bill also distinguishes between rate-regulated electric utilities and different categories of gas companies, which may raise questions about fairness and rate impacts, though the recorded votes show limited opposition overall.
