Estimated Quarterly Tax Payments Calculator

Built for business owners who don’t want surprises at tax time, our free tool helps you calculate estimated taxes in minutes!

Step 1 of 4

Let’s make quarterly taxes feel easy.

This quick calculator was created for sole proprietorship small business owners (Schedule C filers) who want a simple way to see how much to set aside each quarter. No complicated math, just an easy estimate to help you plan ahead.

  • We’ll ask for your projected income and expenses
  • We’ll apply a flat 15.3% rate to estimate your yearly taxes
  • You’ll see your per-quarter amount at the end

This is meant to give you a quick ballpark figure, not official tax advice.
