About EstiMate
EstiMate is a free, no-signup quarterly tax calculator built specifically for self-employed workers, freelancers, and 1099 contractors. We built it because calculating estimated taxes should not require an accounting degree or expensive software.
Why We Built This
Every year, millions of self-employed Americans struggle with estimated quarterly taxes. The IRS expects you to pay taxes four times a year, but figuring out how much to pay is surprisingly complicated. You need to account for federal income tax, self-employment tax, state income tax, deductions, and safe harbor rules, all while trying to avoid underpayment penalties.
Most existing tools are either too basic (ignoring state taxes or SE tax entirely), too expensive (requiring paid subscriptions), or too complicated (designed for accountants, not regular people). EstiMate sits in the sweet spot: comprehensive enough to give you accurate numbers, simple enough to use in under two minutes.
What EstiMate Calculates
- Federal income tax using 2025 tax brackets for all filing statuses
- Self-employment tax (Social Security + Medicare) with correct wage base caps
- State income tax for all 50 states plus Washington D.C.
- Standard and itemized deduction options
- Quarterly payment amounts with due dates
- Safe harbor comparison (current year vs. prior year method)
- Underpayment penalty estimation
