What this estimate leaves out
The calculator starts from your wages, subtracts the Idaho deductions and exemptions for your filing status, applies each band of the 2025 Idaho rate schedule to the remaining taxable income, and then subtracts the credits it models. The step-by-step table and the bracket breakdown above show every figure. For a single filer with no dependents earning the median $81,166, taxable income is $65,066 and the Idaho tax is $3,194, an effective state rate of 3.9%.
Federal income tax uses the 2026 IRS brackets, the 2026 standard deduction and the Child Tax Credit for dependents under 17. At the median household income of $81,166, the combined federal and state income tax for a single filer is $12,220. These figures do not include FICA taxes (Social Security + Medicare, typically 7.65% for employees) or local income taxes, which further reduce take-home pay.
