The Idaho House of Representatives in a party-line vote approved a bill to adopt most of the tax cuts in the federal 'One Big Beautiful Bill Act'. The bill, sponsored by Rep. Jeff Ehlers, would cost the state an estimated $155 million in the current fiscal year and $175 million next fiscal year. Democrats argued the tax cuts would result in harmful cuts to important state services, while Republicans said the bill would provide tax relief to Idahoans.

Why it matters

The tax conformity bill would significantly impact Idaho's state budget, which is already facing mid-year spending cuts and the potential for further reductions. The debate highlights the tension between providing tax relief and maintaining funding for critical state services.

The details

House Bill 559 would apply nearly all the same tax incentives available on federal taxes through the 'One Big Beautiful Bill Act' to state income taxes. This includes provisions such as deductions for workers' tips, no taxes on overtime, and an increased standard deduction for seniors. The business incentives, including a phased approach to fully deducting expenses on research and experimentation, would apply indefinitely.

  • The Idaho House voted 59-9, with two members absent, to send the bill to the Senate for consideration on February 4, 2026.
  • The deductions would apply to 2025 residents' taxes, affecting the state's current fiscal year budget, which ends on June 30.

What they’re saying

“This is a revenue and tax bill, so we're looking at the impact on revenue of a tax policy. This bill says nothing about any budget whatsoever.”

— Jeff Ehlers, State Representative

“It has never been clearer that every single thing we do now will result directly in cuts to vital services.”

— Ilana Rubel, House Minority Leader

“I think this is a good bill. I think it needs to pass. I think we need to move it along and let our accountants do our taxes, so that the state can receive revenues, so that we can all get more money back, and we can spend more money, invest in the economy and generate more revenue.”

— Jason Monks, House Majority Leader

The bill now heads to the Idaho Senate for consideration.
