Our story
We built 1099tax.app as a set of free, complimentary tools to help freelancers, contractors, small business owners and families make sense of taxes, residency and money decisions. There is no paywall and no sign-up. The site survives only on advertising, which keeps the tools free for everyone.
We're a small team who went through these same questions ourselves. We learned what actually worked for us the hard way — through late nights, confusing forms, and more than a few surprises at tax time — and we love helping others find their way faster. Every calculator on this site started as a question we couldn't find a clear answer to, so we built our own.
What we offer
A growing collection of focused calculators and planners. Each one runs entirely in your browser, asks only what it needs, and gives you a clear estimate in seconds:

How we keep it free
The tools are free for everyone, with no account and no hidden upsell. The site is supported by advertising — the ads you see around the calculators are what pay for hosting, data updates and our time. That's the whole model: keep it open, keep it useful, and let advertising carry the cost so no one is ever asked to pay to use a calculator.
How we build the tools
We use official sources — IRS publications, USCIS guidance and state revenue department publications — and we update the figures for the current tax year. The tools give estimates, not tax or legal advice. They're meant to help you understand your situation and ask better questions, not to replace a qualified professional. See our full methodology.
