The 60% Tax Trap at £100,000

At £100,000, you are caught by the Personal Allowance taper — one of the most punishing features of the UK tax system. For every £2 you earn above £100,000, you lose £1 of your £12,570 Personal Allowance. At this salary, you have lost £0 of your allowance.

This creates an effective marginal tax rate of 60% on income between £100,000 and £125,140: the standard 40% higher rate plus an additional 20% from the allowance clawback.

Pension contributions are the most common way to mitigate this trap. Contributing enough to bring your adjusted net income below £100,000 restores your full Personal Allowance, effectively giving you 60p of tax relief for every £1 contributed in this zone.

What is the monthly take home on £100,000?
Your monthly take home pay on a £100,000 salary is £5,713 after income tax and National Insurance. This assumes the standard 1257L tax code, no student loan, and no pension contributions.
Am I a higher rate taxpayer on £100,000?
Yes. With a £100,000 salary, you cross the higher rate threshold of £50,270. Income above this is taxed at 40% instead of 20%. Your effective tax rate is 31.4%, which is lower than 40% because your first £12,570 is still tax-free.
What is the 60% tax trap?
Between £100,000 and £125,140, you lose £1 of Personal Allowance for every £2 earned. This means each extra pound costs you 40p in tax plus 20p from the lost allowance, creating a 60% effective rate. Pension contributions can help by reducing your adjusted income below £100,000.
How much would a 5% pension save on a £100,000 salary?
A 5% salary sacrifice pension on £100,000 would contribute £5,000 per year to your pension while saving you approximately £2,100 in tax and NI as a higher rate taxpayer. Your take home pay drops by less than the pension contribution because of these savings.
How much student loan would I repay on £100,000?
On Plan 2 (the most common), you repay 9% of earnings above £29,385. At £100,000, that is £6,355 per year, or £530 per month. Plan 1 and Plan 4 have different thresholds. Use our full calculator to see the exact amount for your plan.
