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.

UK worker on GBP 50,000

Employer cost GBP 56,893

Salary plus employer NI

Take-home pay GBP 41,364

About GBP 3,447 per month

Tax wedge 27.3%

The full gap between cost and net pay

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.

Formula used here:
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.

## 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: 1. What does my employer actually spend? 2. What lands in my bank account? 3. Which deduction is doing the work? 4. 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. ## Try your own salary 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.

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.
