2026 estimate. Self-employment tax uses the 92.35% factor and the Social Security wage base; income tax is the incremental amount on your net profit after the ½-SE-tax deduction and standard deduction. It does not include the QBI deduction (which may lower it), state tax, or every credit. Not tax advice — confirm with a CPA.
