Free Freelancer Tax Calculator — Estimate Your Tax Bill in 5 Seconds (AU/US/UK)

Tax season is coming. If you're a freelancer, contractor, or sole trader, you need to know how much to set aside for tax.

I built a free calculator that estimates your tax bill instantly:

tax.vemtrac.com (coming online shortly)

What It Calculates

🇦🇺 Australia — Income tax brackets + Medicare levy
🇺🇸 United States — Federal tax + self-employment tax (15.3%)
🇬🇧 United Kingdom — Income tax + National Insurance Class 4

Enter your gross income and business expenses. Get:

  • Total tax owed
  • Effective tax rate
  • Take-home pay (annual, monthly, weekly)
  • Full line-by-line breakdown

Why I Built This

Every freelancer I know guesses their tax bill. Then they get a surprise at tax time. This tool takes 5 seconds and gives you a realistic estimate.
