Senate State Affairs hears warning on tax-conformity risk as budget projections tighten
Summary
Legislative analysts told the Senate State Affairs Committee that uncertainty over whether Idaho will conform to federal tax changes — and how much — could erase recent revenue gains, leaving little on the bottom line and forcing choices about one-time cash, program cuts or structural reforms.
Senator Scott Groh (R‑14) opened the Senate State Affairs briefing by calling tax conformity the committee’s central budget question and urging caution as revenue estimates and a possible conformity adjustment are reconciled.
"The biggest question we're dealing with still is tax conformity," Groh said, noting the legislature adopted a revenue figure that is roughly $155 million higher than the governor's estimate but that conformity rules could consume that margin.
Keith Bybee, division manager in the Legislative Services Office’s Budget Policy Analysis Division, gave a slide-driven presentation that described a recent run of missed sales‑tax collections from December 2024 through August 2025 and weaker-than-expected income and corporate receipts. Bybee said those misses reduced the unobligated cash balance the legislature expected to begin the year — from about $420 million projected down to roughly $313 million, a shortfall on the order of $100 million.
Bybee told the committee the legislature adopted a higher revenue number and included a projected conformity adjustment (about $155 million) in some scenarios. "You add some uncertainty about revenue projections and some additional uncertainty about the tax conformity bill," he said, warning the committee to plan for variability in estimates for items such as tipped wages and overtime pay.
The presentation identified long-term budget drivers: Medicaid (including expansion, which Bybee said has a net general‑fund impact of about $50 million), a $330 million addition for public schools in 2024, costs from shifting public-defender funding to the state, and corrections population growth. Bybee said Idaho’s cash position remains sizeable — he cited nearly $1.7 billion in cash and stabilization funds — but urged the committee to weigh options, including using one‑time cash, cutting programs or pursuing structural changes to return to balance.
Committee members pressed for more detail on the composition of the revenue misses and per-capita spending trends. In response, Bybee described an inflation‑adjusted per‑capita analysis showing roughly $2,500 per person in 2005 rising to about $2,700 by 2026 (about $200 per capita over 20 years), and provided nominal growth figures for public schools (+$1.2 billion from 2017 to 2026) and health and welfare (from about $677 million to $1.2 billion over the measured period). He said he would follow up on migration‑to‑Medicaid details that were not immediately available.
The committee did not take formal action on tax conformity during the meeting. Members framed their next steps as choices between budget strategies — carrying more cushion on the bottom line, pursuing program reductions (including possible Medicaid or education changes in future policy bills), pausing certain transfers, or moving toward structural reform to limit future shocks.
The committee moved on to appointments and other agenda items; staff said more detailed fiscal notes and breakout tables would be provided as bills and RSs advance.
