Typical Idaho refund timeframes
- E-filers: Expect your refund about seven to eight weeks after you receive an acknowledgment that Idaho has your tax return
- Paper filers: Expect your refund about 10 to 11 weeks after we receive your return, as paper returns need to be manually entered into the database.
Idaho refund exceptions
- First-time filers: It takes about three weeks to enter new filers into the system. Until that time, your return may be listed as “not entered in system.” Be sure to add three weeks to the estimates above to determine an accurate refund timeframe.
- Filers who received a letter from the state of Idaho asking for more information: Your refund will be delayed until the requested information is submitted. It then will take about six more weeks to finish the process.
Idaho State tax brackets and tax changes
Idaho residents are taxed on income from all sources except Social Security and railroad retirement benefits. Idaho nonresidents are taxed on Idaho-sourced income, while people who live in Idaho for part of the year are taxed on income received while they are living in Idaho.
Beginning Jan. 1, 2024, Idaho imposed a flat rate of 5.695% (down from 5.8% in 2023) on taxable income that exceeds $2,500 ($5,000 for joint filers, heads of household, and qualifying surviving spouses). This threshold may be adjusted each year to account for inflation.
Check the Idaho State Tax Commission’s 2024 tax updates on their website. You can also always check the Idaho State Tax Commission website for more information on the current tax rates.

Idaho State tax deductions
Idaho taxpayers can claim the standard deduction or choose to itemize their deductions, whichever option results in a higher dollar value is the most advantageous choice. For instance, if your itemized deduction total is more than the standard deduction, you’ll likely want to itemize. The Idaho standard deduction amounts are the same as the federal standard deduction. For 2024:
- Single or married filing separately – $14,600
- Head of household – $21,900
- Married filing jointly or qualifying widow(er) — $29,200
