Idaho self-employment tax, in plain terms
Self-employment tax, 15.3% of your net earnings for Social Security and Medicare, is federal and the same in every state. What differs in Idaho is the income-tax layer. Idaho taxes your self-employment profit at its own rates on top of federal income tax, so your all-in effective rate runs a few points higher than in a no-income-tax state. The calculator above already applies Idaho's brackets, so the number you see is the real one.
Frequently asked
Does Idaho have a state income tax for the self-employed?

How much self-employment tax will I owe in Idaho?
Self-employment tax itself is the same everywhere, 15.3% of 92.35% of your net profit, for Social Security and Medicare. What changes by state is the income-tax layer on top. Use the calculator above with your own numbers; it already applies Idaho's brackets.
Do I pay quarterly estimated taxes in Idaho?
If you expect to owe $1,000 or more in federal tax, the IRS wants quarterly estimated payments (mid-April, June, September, and January). Idaho generally has its own quarterly estimates too when you owe state tax. The calculator shows your next federal quarterly amount.
