An Idaho House of Representatives committee voted along party lines to advance a bill that would adopt nearly all of the tax cuts in the federal 'One Big Beautiful Bill Act.' The bill sponsor says it will provide tax relief for Idahoans, but opponents argue it will hurt funding for programs like Medicaid and public schools.

Why it matters

Each year, Idaho aligns its tax code with federal changes, but the sweeping nature of the federal 'Big, Beautiful' tax cuts has raised concerns over the $155 million impact on the state's budget in an already tight fiscal year.

The details

The House Revenue and Taxation Committee voted to send House Bill 559 to the full House for consideration. The bill would conform Idaho's tax code to the federal changes, including allowing full deductions for research and development expenses starting in 2025. Opponents argued the tax cuts would lead to reductions in funding for Medicaid and public schools, while supporters said they wished the bill went further in aligning with all the federal changes.

  • The House Revenue and Taxation Committee voted on the bill on Monday, February 2, 2026.
  • The bill would apply to Idaho residents' 2025 tax returns.

What they’re saying

“This bill is tax cuts for the people of Idaho. This goes back to the Trump cuts that he made as part of the One Big Beautiful Bill.”

— Rep. Jeff Ehlers, Bill sponsor

“There are thousands of kids and parents just like me who are willing to fight for their kids, and we are very upset that Idaho seems to be wanting to give tax breaks to corporations rather than taking care of their vulnerable.”

— Alicia Mondor, Middleton resident

“The drawback I see with this bill is it does pick winners and losers on the corporate side. We should conform fully on the corporate side, as well and for both years also.”

— Ron Nate, President, Idaho Freedom Foundation

What’s next

The bill will now go to the full Idaho House for debate and a vote.

The takeaway

This bill highlights the ongoing tension in Idaho between providing tax relief and maintaining funding for critical public services like Medicaid and education. As the state grapples with the fiscal impact of conforming to federal tax changes, lawmakers will have to weigh the tradeoffs carefully.
