How Idaho taxes your paycheck
Idaho keeps it simple: a 5.3% flat tax on income over $4,811 (first $4,811 exempt). Your state taxable income is your gross pay minus the standard deduction, then the flat rate applies to every dollar above that.
The 2026 standard deduction is $16,100 (single), $32,200 (married filing jointly), $24,150 (head of household).
On exemptions: Idaho conforms to the federal personal exemption, which is $0 for 2026 (OBBBA made the TCJA $0 exemption permanent).

Example: a $75,000 salary in Idaho
On a $75,000 salary as a single filer: federal taxable income is $75,000 − $16,100 = $58,900, giving $7,670 of federal tax. State taxable income is $58,900, giving $2,867 of state tax. FICA takes $4,650 (Social Security) + $1,088 (Medicare). Estimated take-home: $58,726 per year ($2,259 per biweekly paycheck).

Methodology & sources
State figures come from the site's versioned 2026 tax dataset (v1.0.0, researched 2026-10-11),
regenerated into this page automatically. Model: state taxable income = gross pay minus the state's 2026
standard deduction;
state brackets applied marginally; employee-paid state payroll taxes added at their 2026 rates and wage bases
(with published annual caps). Federal tax uses 2026 IRS brackets and standard deductions; FICA uses the 2026
Social Security wage base ($184,500) and Medicare rates. Personal exemption credits/deductions and
individual tax credits are not modeled — the result is an estimate, not a tax return.
