Frequently Asked Questions

What's the difference between the Business and Business Unlimited plans?

Business ($69/quarter or $196/year) is built for accountants and small practices managing up to 10 clients. Business Unlimited ($169/quarter or $499/year) is designed for tax professionals and firms with unlimited client management, team collaboration, and firm-branded reports. Annual billing saves you up to 29% versus paying quarterly.

Can I upgrade or downgrade my plan anytime?

Yes, you can change your plan at any time. When upgrading, you'll have immediate access to new features. When downgrading, changes take effect at your next billing cycle.

Is the Personal plan really free forever?

Yes! The Personal plan is the complete calculator, free forever — full federal and state calculations using safe harbor and annualized methods, covering wages, self-employment, business, rental, and investment income. You also get a detailed PDF report, saved calculation history, and the ability to send your results to your accountant for review. It's limited to one calculation (plus revisions) per quarter and requires a free account.

What do the paid plans add over Personal?

The calculations are identical on every plan — paid plans don't unlock a "better" calculator. Business and Business Unlimited are built for tax professionals: they add the ability to manage multiple clients (up to 10 on Business, unlimited on Business Unlimited), a client management dashboard, unlimited calculations, and firm-level reporting. If you're calculating taxes just for yourself, Personal is all you need.
