Doing your own taxes?

Frequently asked questions
Is the Free plan really free?
Yes. The Free plan is the complete calculator. You get the federal safe harbor and annualized methods, covering wages, self-employment, business, rental, and investment income, plus your state's safe harbor payment schedule, with quarterly deadline reminders. It's limited to one saved calculation per quarter, plus one correction within 24 hours of saving it, and requires a free account. Unlimited calculations, the PDF report, saved history, and the year-end Form 2210 package are part of Plus.
What does Plus add?
For $99/year, Plus turns the calculator into a year-round tool. Revise your calculation anytime your income changes, keep every quarter in saved history, download the quarterly PDF tax report for your records, and at filing season get the Form 2210 / Schedule AI package that shows the IRS your payments matched your income. Only need it for a single quarter? Plus is also sold quarterly at $29, and you can cancel after the quarter you paid for. The Form 2210 package covers a finished year, so it opens in January, and a quarter bought earlier in the year ends before then.
Which states are covered?
All 50 states plus Washington, D.C., on every plan including Free. The state figure is the safe harbor, based on last year’s state tax, not a full state calculation. If your state has no income tax, the calculator tells you that too, and your federal number is the whole picture.
Do I still need my accountant?
This does one job precisely (quarterly estimated payments using IRS Publication 505 methods) and it works alongside an accountant, not instead of one. Many users run their own numbers here and have their accountant review the result.
Is my financial data private?
Your data is never sold and never shared with third parties. We use it to calculate your taxes and for nothing else.
Does Plus calculate taxes more accurately?
No. The calculation engine is identical on Free and Plus. Plus adds year-round tools (unlimited calculations, records, and year-end IRS forms). If you only need a number each quarter, the Free plan is all you need.
Can I try it before paying?
Yes. Free is the full engine, no credit card. It IS the trial. Plus runs the same calculations with year-round tools, and it carries a 30-day money-back guarantee.
Can I change plans later?
Anytime. Move from Free to Plus whenever you need it. If you cancel, your account goes back to Free at the end of the period you paid for.
How do I cancel?
Anytime, from your billing page. No emails, no phone calls. Your plan stays active through the period you've paid for, and you won't be charged again. Within the first 30 days, contact us for a full refund.
Start free. Upgrade when you need more.
Your quarterly number costs nothing, federal and state. Add year-round management when you're ready.
