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.
