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.

Step 1: Let’s look at your numbers.

Enter what you expect to earn and spend this year in your business. We’ll find your net profit by subtracting expenses from income.

Use your best estimate for the year ahead
If you’re unsure, rounding is perfectly fine
