What else to know about Idaho taxes
Idaho taxes income at a flat 5.3%, but the first $4,811 of taxable income ($9,622 for married couples and heads of household) is taxed at 0%. Those zero-rate amounts are the 2025 figures from the 2025 Form 40 instructions; Idaho indexes them each year and had not published the 2026 amounts when we checked.
Idaho's withholding tables ignore the 0% band, so actual withholding can be slightly higher than the tax estimated here.
Idaho follows the federal standard deduction and has no separate personal exemption. Idaho child and grocery credits are not included.
What this estimate does not include
Tax credits, itemized deductions, other income, overtime, bonuses and post-tax deductions are not included, and actual withholding follows your Form W-4 and Idaho's own withholding rules. Use it as a planning estimate. For the method and the federal rules, see the main paycheck calculator.
