Freelance tax, without the spreadsheet. Log income. Know what to set aside. Never miss an IRS deadline. Built on the safe harbor rule: pay 100% of last year's tax across 4 payments (110% over $150K AGI) and the IRS won't penalize you — we calculate that number in 60 seconds of setup. FREE FOREVER — no trial, no card: • Your quarterly set-aside number (safe harbor or income projection) • Every IRS deadline with a countdown • Three factual reminders per quarter (2 weeks, 3 days, due day) • Your state's own deadlines when they differ from the IRS — Virginia asks by May 1, Delaware April 30, Hawaii on the 20th, Iowa at month end • A set-aside tracker: what you have put away against what this quarter needs, and roughly what share of each payment gets you there • A one-tap link to pay on IRS.gov when the quarter comes due • Income log with CSV import — paste straight from your invoicing app • We tell you if you are under the $1,000 federal threshold, where the IRS does not ask for quarterly payments at all • Year overview with paid/upcoming status PREMIUM — pay the least you legally can, and know what April holds: • What to set aside from each payment — not a flat rule, but the real tax that payment causes. Past the Social Security cap the rate drops sharply and a flat rule keeps over-saving your money • What April actually looks like: safe harbor stops the penalty, not the bill. We show it building up on income you have already been paid — a running total, never a forecast • Your household, not just your invoices: a spouse's salary, withholding and a retirement contribution each move what you owe by thousands • Your state's tax folded into every quarterly figure • The state rules that change what you owe: California splits the year 30/40/0/30 instead of four equal payments, and the point where a state starts asking varies — South Carolina at $100, New York at $300, while the IRS waits for $1,000 • Income by client: who paid what, how many entries, and what share of your year each one is • How much you can put into a retirement plan: your SEP-IRA and solo 401(k) room worked out from your own profit, and what each contribution takes off this year's bill. For most freelancers a solo 401(k) allows far more than a SEP — and nobody tells them • A year-end pack for your accountant: income by client, every payment with its confirmation number, estimated vs actual, Schedule C basis — one PDF you can send • CSV export as a real file you can share • A home screen widget: your number and the countdown, without opening the app We only cover a state once we have checked its rules with that state's own tax authority. Every income-tax state except Connecticut is covered today — 40 states plus DC. If yours is not, the app says so and does not charge you for it. Idaho and Utah do not ask individuals for quarterly payments at all, and we say that instead of showing you deadlines that do not exist. Why trust it: • 2026 IRS numbers verified against irs.gov and ssa.gov (Rev. Proc. 2025-32); updated every December • Everything stays on your device — no account, no bank login, nothing leaves your phone • Deadlines follow the IRS rule for weekends and holidays and are checked against every date the IRS has published since 2016 This isn't a filing tool. We estimate what to set aside and remind you when it's due; your accountant or filing software handles the return. Estimates only — not tax advice.
