Some Idaho Tax Refunds Delayed Due to New Tax Law Changes; Here’s When Taxpayers Can Expect Payment
Why It Matters
Thousands of Idaho taxpayers who filed their state returns early are waiting longer than expected for their refunds — a delay tied directly to recent changes in state tax law. For households counting on those refunds to cover bills or other expenses, understanding the timeline and the reason for the holdup is critical.
The good news: the delays are temporary, and the new deductions behind the slowdown may actually put more money back in taxpayers’ pockets.
What Happened
Idaho residents who filed state tax returns before March 10 encountered a processing delay caused by a timing conflict between early filings and new tax code updates. The Idaho State Tax Commission had to update its forms and internal systems to incorporate new deductions before it could fully process those early returns.
The deductions were added when Idaho lawmakers updated the state tax code to align with new federal provisions included in what has been called the “One Big, Beautiful Bill Act.” The changes introduced an enhanced senior deduction and new tax breaks covering tips, car loan interest, and overtime pay.
Idaho State Tax Commission spokesperson Renee Eymann confirmed the issue, explaining that returns submitted before the system updates were temporarily paused. “It took us a little bit of time to adjust our forms and our systems so that we could incorporate those deductions,” Eymann said. “And people who filed before that happened, that did delay their refunds a little bit.”
Boise taxpayer Robert Hoffman experienced the situation firsthand. His tax preparer advised him to hold off on paying even after filing early — a decision that paid off. “After all said and done, we got another $600 deduction off the total bill. So, we’re happy about that,” Hoffman said.
By the Numbers
- March 10: The cutoff date — those who filed before this date experienced refund delays
- End of May: Expected deadline by which early filers should receive their refunds
- 7–8 weeks: Normal processing time for electronically filed returns going forward
- 10–11 weeks: Normal processing time for paper filings
- 600,000+ returns already received by the Tax Commission, with more than 1 million expected by the close of tax season
- $600: Additional deduction one early filer received under the updated tax code
Zoom Out
Idaho’s situation reflects a broader challenge facing state tax agencies across the country when Congress passes major federal tax legislation. States that tie their tax codes to federal law must scramble to update their own systems before they can process returns that claim new deductions — a lag that can ripple through thousands of filings.
The new deductions for tips, car loan interest, and overtime pay are among several taxpayer-friendly provisions that align with President Donald Trump’s broader tax relief agenda. For working Idahoans, particularly seniors and hourly wage earners, the updated deductions represent meaningful savings — even if the refund timing has been frustrating.
State officials also emphasized that the Tax Commission’s work does not stop when the April 15 deadline passes. “We’re still working because we’ve got all those tax returns that will come in the last day, so we still have to go through and process all those as well,” Eymann said.
What’s Next
The Idaho State Tax Commission is hosting its annual curbside drop-off event on April 15 at the Boise office, allowing taxpayers to drive up and submit their returns in person without leaving their vehicles.
Taxpayers who filed before March 10 are advised to expect their refunds no later than the end of May. Those who filed after March 10 are now on standard processing timelines and should not experience the same delays.
Idaho residents looking to stay current on state policy and government services can also follow ongoing developments, such as the recent Idaho Governor’s signing of legislation reforming oversight of youth residential treatment homes, as lawmakers continue shaping the state’s regulatory landscape. Additionally, North Idaho residents recovering from last year’s windstorms may want to check whether they qualify for FEMA disaster assistance available to affected counties.
Officials encourage any taxpayer with questions about their refund status to contact the Idaho State Tax Commission directly.
