Frequently Asked Questions

Your tax-free Personal Allowance shrinks by £1 for every £2 you earn above £100,000, disappearing entirely once you reach £125,140 — an effective marginal rate above 60% in that band, since you lose both the allowance and pay 40% tax on the extra income.

No — Scotland sets its own Income Tax bands and rates, which differ from the rest of the UK. This calculator covers England, Wales, and Northern Ireland only. National Insurance rates are the same UK-wide.

Salary-sacrificed pension contributions come out of your pay before Income Tax and National Insurance are calculated, so they reduce your taxable income directly — which is why the net pay drop is smaller than the contribution itself.

National Insurance contributions count toward your entitlement to the State Pension and certain other benefits, alongside funding the NHS and welfare system — it's separate from Income Tax even though both come out of your pay.
