Understanding Your Tax Burden
At $100,000 gross income in Idaho, your marginal federal tax bracket is 12% â but your effective federal rate is only 8.0% because the progressive tax system taxes different portions of your income at different rates. Idaho's 5.8% state income tax adds $5,800 to your annual tax bill.
Your total effective tax rate of 21.5% means you keep $78,518 out of every $100,000 earned (78.5%). For strategies to reduce your tax burden, consider maximizing 401(k) contributions ($23,500/year for 2025), HSA contributions, and itemizing deductions if they exceed $14,600.
