Where Does a £100,000 Salary Sit in the UK?
A gross salary of £100,000 is in the top 5% of UK earners. Reaching £100,000 is a major milestone, but it also triggers one of the most significant tax traps in the UK system: the personal allowance taper. For every £2 you earn above £100,000, you lose £1 of your £12,570 personal allowance, creating an effective marginal tax rate of 60% on income between £100,000 and £125,140.

How to Maximise Your Take Home on £100,000
Address the personal allowance taper immediately. The taper creates an effective 60% tax rate on income between £100,000 and £125,140. The most effective solution is salary sacrifice into your pension to bring your adjusted net income below £100,000. This recovers your full £12,570 personal allowance, saving over £5,000 in tax. Read our detailed £100,000 tax trap guide.
Maximise pension contributions via salary sacrifice. At £100,000, the combined tax and NI saving on salary sacrifice is exceptional. Every £1 sacrificed within the taper zone costs you only 40p in real terms. Use our salary sacrifice calculator to model your specific scenario.
Review your full tax picture annually. At this level, consider child benefit charges, pension lifetime allowance issues (though the lifetime allowance was abolished from April 2024, the lump sum allowance still applies), and whether additional strategies like VCTs or EIS make sense. Our high earner tax tips and legal tax reduction guide cover the options.
