About United Kingdom's Tax System
The UK uses a banded income tax system with a tax-free Personal Allowance of £12,570. Income above this is taxed at the basic rate (20%), higher rate (40%), and additional rate (45%).
National Insurance (NI) is effectively a second income tax: employees pay 8% on earnings between £12,570 and £50,270, then 2% on earnings above. Combined with income tax, the marginal rate can reach 47% (or higher with student loan repayments).
Scottish taxpayers pay different rates set by the Scottish Parliament, including starter (19%) and intermediate (21%) bands not available in the rest of the UK.
The Personal Allowance tapers for incomes above £100,000, creating an effective 60% marginal rate between £100,000 and £125,140.
