Self-employed tax estimator
Estimate your 2026 federal self-employment tax, income tax, and quarterly payments in a few seconds. No signup needed.
An estimate, not tax advice. This calculator is federal only and keeps
things simple on purpose: it assumes the standard deduction and no other income, and it
leaves out state tax, the QBI deduction, the Additional Medicare Tax, and credits. It
applies the 2026 figures: 92.35%
of profit subject to the 15.3% self-employment tax (Social Security capped at
$184,500), then the standard deduction and ordinary
brackets for your filing status. Confirm your real numbers with a tax professional.

Lower that taxable profit: track every deduction
Whittle snaps receipts, tags each expense with its tax year, and exports Schedule C-ready records at filing time.
