The Idaho State Tax Commission is providing an update on claiming the new conformity deductions on 2025 Idaho income tax returns.
The Tax Commission has programmed its systems to automatically give the larger standard deduction amounts to taxpayers who take the standard deduction on their 2025 income taxes. This means that those taxpayers who’ve already filed their taxes won’t need to file amended returns to claim the larger standard deduction.
Taxpayers who want to claim the other conformity deductions will need to wait until the Tax Commission provides guidance on how to do this. These other deductions include the enhanced senior deduction and the deductions for qualified tips from wages, car loan interest, and overtime compensation.
The Tax Commission anticipates updating its forms and systems with the conformity changes by mid-to-late March. At that time the agency will provide instructions on how to claim the deductions on their taxes.
Taxpayers who are concerned about the timing of the changes and the tax due date can get an automatic filing extension by making sure they’ve paid enough of their tax by April 15. To qualify, they should either pay 80% of the estimated tax they owe for 2025 or 100% of the total tax reported on their 2024 income tax return (if they filed a return). They can use the worksheet on Idaho Form 51 – Voucher (https://tax.idaho.gov/documen
