Frequently asked questions

How accurate is TaxBite?

We use HMRC-style bands and thresholds for the selected tax year. Results are estimates — your payslip may differ with benefits, tax-code adjustments, or emergency codes.

Does this work for Scotland?

Yes. Choose Scotland in the region dropdown to apply Scottish Income Tax bands while NI remains UK-wide.

Can I calculate a bonus?

Open Advanced Features and enter a bonus amount. We’ll show the marginal bite and your bonus take-home.

Is my salary data private?

Yes. Calculations run entirely in your browser. We don’t upload your salary figures to a server.

Is TaxBite free?

Yes — free forever. Optional ads after results help keep the calculator running.
