  3. Log what goes outPick a category from the dropdown. Meals count at 50% automatically.
  4. Move the moneyThe dashboard shows your set-aside %. Transfer it to savings the day you get paid.

About

Built for the people who invoice.

Quarterwise started from a simple frustration: freelance money arrives in lumps, and the tax bill shows up months later. Bookkeeping software is great but often more than a solo designer, writer or developer needs. A good spreadsheet is enough if it does the math for you.

Every template uses the IRS's published formulas and dates, shows its assumptions in plain English, and works offline in tools you already have.

"Organize and estimate, clearly. Never pretend to be your accountant."The Quarterwise rule

FAQ

Questions

Is this tax advice?

No. Quarterwise templates organize your numbers and estimate using simplified IRS math. Confirm your actual amounts with IRS Form 1040-ES or a tax professional.

Does it work in Google Sheets?

Yes. Upload the .xlsx to Google Drive and open it with Google Sheets. Formulas, dropdowns and the dashboard all carry over. It also opens in Excel and Apple Numbers.

What if I also have a W-2 job?

Enter your W-2 wages in Settings. The tracker caps the Social Security part of self-employment tax at the 2026 wage base ($184,500), counting your W-2 wages first.

Is it a subscription?

No. You pay once and keep the file. A new edition comes out each tax year.

What's your refund policy?

If the file doesn't work as described, email us within 30 days for a fix or a full refund.
