Frequently Asked Questions
Which tax brackets does this use?
It applies representative national progressive income-tax brackets for the US (federal), UK and Canada (federal). It is a simplified estimate and does not include state, provincial or local taxes.
What is an effective tax rate?
Your effective tax rate is total tax divided by total income. It's lower than your top marginal bracket because progressive systems tax each band of income at a different rate.
Is this a substitute for tax advice?
No. It's a planning estimate. Deductions, credits, filing status and local taxes affect your real bill — consult a qualified tax professional for filing.
Are my income figures private?
Yes. The calculation runs entirely in your browser and nothing you enter is transmitted or stored anywhere.
