Estimates using federal brackets, FICA and your state rate. Not tax advice.
Idaho uses a flat state income tax rate of 5.3 percent on wages for 2026. A flat rate means every dollar of taxable wage income is taxed at the same percentage regardless of earnings level. Idaho consolidated from a graduated schedule to this single flat rate, making it simpler to estimate your state tax liability. The state allows a standard deduction and personal exemption that reduce taxable income before the rate applies.
On a $65,000 salary, Idaho state income tax is roughly $3,445 per year, or about $287 per month. Because the rate is flat, that percentage holds consistently across income levels. Your actual withholding may differ slightly based on your Idaho Form ID W-4 elections and the deductions you claim on your annual return.
Idaho does not impose a local wage income tax at the city or county level. The calculator applies federal income tax brackets, FICA, and Idaho's 5.3 percent flat state rate to your paycheck. You can adjust the state rate field if you want to model a different scenario. Results are estimates only and are not tax advice.
