Most Freelancers Find Out in April. By Then It's Too Late.

Penalties, surprise tax bills, and scrambling for cash at filing time are the norm for self-employed professionals. The IRS requires quarterly estimated payments, but most freelancers either overpay (giving the government an interest-free loan) or underpay (incurring penalties).

The gap isn't effort—it's visibility. Without a 60-second calculation at the start of each quarter, you're guessing what to set aside. This calculator eliminates the guesswork.

    Common Questions

    How is this different from what TurboTax does?

    TurboTax is a filing tool—it calculates your taxes after the year is over and prepares your return. This calculator is a planning tool—it helps you estimate what you owe during the year so you can make timely quarterly payments and avoid penalties. They serve different purposes. Many freelancers use both.

    Do I need this if I already have an accountant?

    If your accountant handles your quarterly estimates, you may not need it. But if you want to check their work, understand how your estimates are calculated, or run your own scenarios without billing hours, this gives you visibility into your own numbers.

    Does this work for 2026?

    Yes. The calculator is built with 2026 tax year rates: self-employment tax rate, standard deduction, tax brackets, and quarterly due dates.

    Can I use this for previous years?

    The rates are set for 2026. If you need it for 2025, you would need to adjust the rates manually in the input cells.
