No — this is a planning and forecasting tool, not a tax filing service. Use it throughout the year to estimate what you'll owe and set money aside. You'll still file with a CPA or tax software at year end.
Results are estimates for planning purposes based on 2026 projected federal tax brackets and state income tax rates. Individual circumstances vary — always consult a licensed CPA or tax professional before filing or making financial decisions.
As a 1099 worker, you pay both the employee and employer share of Social Security and Medicare — a combined 15.3% on top of income tax. This calculator shows you exactly how much that is so you can set it aside quarterly instead of getting hit with a big bill in April.
If you earn over ~$40,000 from self-employment, electing S-Corp status can significantly reduce your self-employment taxes. The calculator estimates your annual savings so you can decide if it's worth discussing with your CPA.
All 50 states and Washington D.C. are included with their 2026 estimated income tax rates.
All calculations run entirely in your browser — no financial data is ever sent to a server. Your account details are stored locally on your device only. See our Privacy Policy for full details.
