How company tax works
Company tax is your taxable profit times the corporate rate. A Australia company with a $100,000 profit pays $30,000 at the 30% headline rate — or $25,000 as a base-rate entity. Many countries tax smaller companies at a lower rate, which you can toggle on where it applies to all income.
| Country | Headline | Small / base rate |
|---|---|---|
| Australia | 30% | 25% |
| United States | 21% | — |
| United Kingdom | 25% | 19%* |
| India | 25% | 22% |
| Canada | 15% | 9%* |
Headline rates only — surcharges, state/provincial tax and turnover thresholds are noted in the tool but not added.* The reduced rate is threshold-based (UK marginal relief, Canada’s first $500k), so it’s shown for reference — the calculator applies the headline rate for these.Other countries’ reference rates are in the rates table.

Company tax — common questions
Which countries does this cover?
Australia, the United Kingdom, the United States, Canada and India — the countries with source-verified company-tax rates. Other countries' reference rates are in the tax-rates table; Fin won't show a company-tax figure it can't source.
How is company tax calculated?
For most companies it is simply your taxable profit multiplied by the headline rate (e.g. 30% in Australia, 25% in the UK). This tool shows the headline rate; surcharges, state/provincial tax and turnover thresholds are noted but not added.
What is the small-business / base-rate company rate?
Several countries tax smaller companies less — Australia 25% for base-rate entities (turnover under $50m), the UK 19% for small profits, Canada 9% for the small-business rate, India 22% concessional. Toggle "small / base-rate company" to apply it.
Does this include state or provincial tax?
No. The US 21% is the federal rate only (states add 0–~12%); Canada 15% is the federal general rate (provincial tax is extra). The note beside each result spells this out.
