Stop Guessing What You
Owe the IRS This Quarter
1099 Freelancer Tax Estimator PRO calculates your exact self-employment tax, quarterly payment amount, and total tax bill — with a deduction finder, QBI calculator, and S-Corp savings analyzer built right in.
Most Freelancers Find Out What They Owe Too Late
Self-employment tax catches first-year freelancers off guard nearly every time — and missed quarterly payments mean penalties on top of the bill you already weren't expecting.
Surprised by a Huge Tax Bill?
No employer withholds tax from 1099 income. Many freelancers discover in April that they owe 25–30% of their net profit — federal income tax plus 15.3% self-employment tax combined.
Missed a Quarterly Deadline?
The IRS expects estimated payments four times a year. Miss one, or underpay, and an underpayment penalty applies — even if you pay everything owed by April 15.
Leaving Deductions on the Table?
Home office, mileage, health insurance, retirement contributions, and the QBI deduction can each cut thousands off your taxable income — most freelancers claim only a fraction of what they qualify for.
Everything You Need to Plan Your Freelance Taxes
Built specifically for the US market. Handles Schedule C income, Schedule SE tax, QBI deduction, and quarterly estimated payments.
Built-In Tax Advisor — No API Key
Ask plain-English questions — "how much should I pay quarterly," "should I elect S-Corp," "what deductions am I missing" — and get answers generated from your actual numbers, instantly, with no internet connection needed.
✨ EXCLUSIVEQuarterly Vouchers + Safe-Harbor Shield
Four ready-to-pay 1040-ES vouchers with exact due dates and amounts, plus a safe-harbor calculator (90% current-year or 100–110% prior-year) so you know exactly what protects you from a penalty.

FULL BREAKDOWNS-Corp Election Savings Analyzer
