UK workers' tax wedge: what your employer pays vs what you keep
Income tax is only part of the story. For an employee, the better question is: how much does the employer spend, and how much of that money reaches the worker?
That gap is the tax wedge. In the UK it includes income tax, employee National Insurance, and employer National Insurance. It sits between the salary on the contract and the full cost of employing someone.
The visible tax rate on that salary is lower. PopaDex calculates income tax plus employee NI at 17.3% of gross salary. Add employer NI and the full wedge rises to 27.3% of employer cost.
Tax wedge = (employer cost - net pay) / employer cost.
Figures come from the PopaDex calculator database for a single worker with standard deductions. Amounts are rounded to the nearest whole currency unit.
The UK tax wedge at different salaries
The UK wedge climbs with income. Employer NI grows with salary, income tax moves through higher bands, and the worker keeps a smaller share of the total employment cost.
| Gross salary | Employer cost | Net pay | Income tax | Employee NI | Employer NI | Tax wedge |
|---|---|---|---|---|---|---|
| GBP 25,000 | GBP 28,393 | GBP 21,912 | GBP 2,335 | GBP 753 | GBP 3,393 | 22.8% |
| GBP 50,000 | GBP 56,893 | GBP 41,364 | GBP 7,198 | GBP 1,438 | GBP 6,893 | 27.3% |
| GBP 75,000 | GBP 85,393 | GBP 56,294 | GBP 16,583 | GBP 2,123 | GBP 10,393 | 34.1% |
| GBP 100,000 | GBP 113,893 | GBP 70,883 | GBP 26,309 | GBP 2,808 | GBP 13,893 | 37.8% |
| GBP 150,000 | GBP 170,893 | GBP 100,061 | GBP 45,761 | GBP 4,178 | GBP 20,893 | 41.5% |
What the numbers show
Employer NI still matters
At GBP 50,000, the employer pays GBP 6,893 above salary. The worker never sees that line on a payslip, but the company still budgets for it.
The wedge rises fast
The jump from GBP 50,000 to GBP 100,000 raises the wedge from 27.3% to 37.8%. The worker keeps more pounds, but a lower share of the total employment cost.
Net pay is the practical number
A GBP 75,000 salary becomes about GBP 56,294 net, or GBP 4,691 per month. That is the number that has to cover rent, savings, and ordinary spending.
The wedge is not your payslip tax rate
On GBP 50,000, the employee effective tax rate is 17.3%. The tax wedge is 27.3% because it also counts employer-side contributions.
UK vs other countries
The UK is not a high-tax-wedge outlier at GBP 50,000. In the PopaDex country data, Germany, Belgium, France, Italy, Portugal, and Sweden all show a higher wedge at the same nominal salary in each country’s local currency. Switzerland, Australia, and the United States show a lower wedge.
This is not a purchasing-power comparison. GBP 50,000, EUR 50,000, CHF 50,000, and USD 50,000 do not buy the same lifestyle. This chart compares tax systems at a round local salary.
What most tax-wedge charts miss
Tax-wedge graphics are useful, but many are built for policy papers rather than phones. They also tend to start with the economy, when most readers are trying to understand a payslip or a job offer.
A worker usually wants four answers:
- What does my employer actually spend?
- What lands in my bank account?
- Which deduction is doing the work?
- How does this compare with another country or job offer?
This version starts with one salary and one worker. On mobile, the first screen gives you the employer cost, net pay, and wedge. The table is there for readers who want the breakdown.

Use the PopaDex calculator to change the salary, country, or currency. It shows income tax, employee social security, employer social security, monthly take-home pay, and total employer cost.
You can also compare countries side by side:
- United Kingdom vs France
- United Kingdom vs Germany
- United Kingdom vs United States
- Select any two countries
Methodology
The figures in this post come from the PopaDex tax calculator data model:
- Gross salary: the contractual salary entered by the user.
- Employee deductions: income tax plus employee social security contributions.
- Employer cost: gross salary plus employer social security contributions.
- Net pay: gross salary minus employee deductions.
- Tax wedge: employer cost minus net pay, divided by employer cost.
All calculations assume a single worker with standard deductions. Real payslips can differ because of pension contributions, student loans, salary sacrifice, benefits, local rules, special regimes, and personal circumstances. Use this as a planning comparison, not tax advice.
