The combined marginal rate for freelancers here can exceed 43% on income in the 22% federal bracket. Careful quarterly estimated payment planning is critical to avoid underpayment penalties. This calculator factors in Idaho's state tax and the deductible half of SE tax to give you an accurate picture.

Idaho levies a flat 5.3% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 5.3 cents goes to Idaho. Idaho does not impose local income taxes, so the 5.3% flat rate is the only state-level income tax you owe.
