BOISE, Idaho — The Idaho State Tax Commission says taxpayers who already filed their 2025 state income tax returns and claimed the standard deduction will automatically receive the new, larger deduction amounts under the recently passed tax conformity law.
Those filers do not need to amend their returns to receive the increased standard deduction.
However, taxpayers who want to claim other new conformity deductions — including the enhanced senior deduction and deductions for qualified tips, overtime pay, and car loan interest — will need to wait for further guidance.

The commission expects to update its forms and systems by mid-to-late March and will provide instructions at that time, according to a press release.
The deadline to file 2025 Idaho income taxes remains April 15. Taxpayers can qualify for an automatic extension if they pay at least 80% of what they owe for 2025 or 100% of what they owed in 2024 by the deadline.
