Self-Employed Tax Calculator — Stop guessing what you owe. This estimator calculates your self-employment tax and federal income tax on your 1099 income, and tells you exactly what to set aside each quarter - so tax season is never a surprise.

What's inside

• Dashboard: your total estimated tax, what to set aside each quarter, your effective rate and take-home

• Income: your 1099 income from every client or platform

• Deductions: your business write-offs, which lower the income you're taxed on

• Tax Calculation: self-employment tax (15.3% on 92.35%, Social Security capped at the wage base) plus federal income tax using the 2026 IRS brackets - applied progressively, not as a flat guess

• Quarterly: your estimate split into four payments with the usual IRS due dates

• How to Use: how the tax works, and what it does and doesn't include

Who it's for Freelancers, 1099 contractors, gig workers and small business owners (sole proprietors and single-member LLCs) who want to know their tax before the year ends.
