The £100,000 trap: why your effective tax rate hits 60%
Software engineers earning between £100,000 and £125,140 face one of the UK's most punishing effective marginal rates: 60%. This happens because:
- Income tax rate in this band: 40% (Higher Rate)
- Personal Allowance clawback: for every £2 over £100k, you lose £1 of your £12,570 allowance
- This £1 loss is taxed at 40%, making the effective rate on every £1 above £100k: 40% tax + 20% PA clawback effect = 60%
On £120,000, you pay approximately £47,000 in income tax alone. Pension contributions into a company pension scheme are one of the most effective ways to reduce this exposure — every £1 put into a pension reduces income in this band at the full 60% marginal saving rate.
FAQ — Software engineer salary after tax in the UK
On £80,000 gross salary in the UK (2026/27), take-home pay is approximately £56,500/year (£4,708/month). Income tax is £24,432 (20% basic + 40% higher rate) and National Insurance is £4,754 (8% basic + 2% upper). Effective tax rate: ~29.4%.
UK software engineers operating via a limited company (outside IR35) can typically extract income more tax-efficiently: a low salary (around £12,570) plus dividends (taxed at 8.75%/33.75% depending on band). On equivalent £100,000 earnings, a contractor might net £68,000–£72,000 vs. ~£66,000 as a PAYE employee — but must account for employer NI, accountancy costs, and no employment benefits. IR35 status is critical.
The most impactful legal options for PAYE software engineers:

2. Cycle to work scheme — save 20–45% on bike cost
3. Electric car salary sacrifice — can save £3,000–£6,000/year at mid-to-senior salaries
4. Remote working (if genuinely outside London) — reduces overall cost of living, similar net real income
