The calculator annualizes your gross wages based on pay frequency, estimates taxable income using a federal-conforming standard deduction model, applies Idaho’s zero-rate band on taxable income, then applies 5.3% on the taxable amount above that band (filing-status dependent thresholds). It adds federal bracket tax and FICA payroll taxes, then returns a per-pay-period take-home estimate.
Gross Pay - Federal Tax - ID State Tax - Social Security - Medicare ≈ Net PayIdaho state withholding in this model is driven by taxable income after a standard deduction-style offset, then the Idaho zero band and flat rate on the excess. Actual paystubs may include additional items such as retirement contributions and health premiums.
Gross wages flow through federal tax, Idaho tax, and FICA to produce net pay.
