The 60% Marginal Rate Trap
This is often confusing. The highest official income tax band is 45%, so how can you pay 60%? The math is devious but simple:
- You pay 40% tax on the £5,000 earnings (£2,000 tax).
- Because you earned that £5,000, your tax-free Personal Allowance drops by £2,500.
- This previously tax-free £2,500 is now taxed at 40%, costing you an extra £1,000.
- Total Tax on £5,000 = £2,000 + £1,000 = £3,000.
- £3,000 is 60% of £5,000.

Frequently Asked Questions
1. How much is £105k after tax in the UK?
Based on 2026 projections, your take-home pay is approximately £62,213 per year. This breaks down to roughly £5,184 per month. This figure assumes you have Plan 2 student loans or specific pension contributions that align with standard deductions for this bracket.
2. Why is my tax rate so high on £105k?
You are paying a 40% Higher Rate tax, plus an additional effective 20% due to the tapering of your Personal Allowance. This creates a 60% marginal tax rate on income between £100,000 and £125,140.
3. Should I increase my pension contributions?
For most people earning £105,000, increasing pension contributions by £5,000 annually is highly tax-efficient. It prevents the loss of Personal Allowance and gives you immediate tax relief of 40-60% on the contributed amount.
4. Do I need to register for Self Assessment?
Yes. HMRC usually requires anyone earning over £100,000 (adjusted net income) to file a tax return. This is crucial for claiming back the full tax relief on your pension contributions and ensuring your tax code is correct.
5. How does the Personal Allowance taper work?
Your tax-free allowance (£12,570) is reduced by £1 for every £2 you earn above £100,000. At £105,000 earnings, your allowance is reduced by £2,500 (£5,000 excess / 2).
6. What about National Insurance?
You pay Class 1 National Insurance. In 2026, the rate drops to 2% for earnings above the upper threshold (£50,270). Your total NI bill will be approximately £3,955 for the year.
7. Is £105k considered rich in the UK?
Statistically, yes. You are in the top 2-3% of all income taxpayers. However, "rich" is subjective and depends on location (London vs. North), family size, and housing costs.
