Switzerland keeps more at essentially every salary, and the advantage widens as you earn: 4.9 points at the equivalent of £50,000, 12.8 points at £120,000.
But the canton matters nearly as much as the country. On the same salary an employee keeps 81.4% in Zug and 72.6% in Geneva, a spread of 8.8 points from location alone.

Open the Canton ComparatorThe Swiss advantage grows with salary
The share of gross kept after federal, cantonal and communal tax and employee social contributions, in the canton of Zurich. Independent of the exchange rate.
| Equivalent salary | UK keeps | Zurich keeps | Swiss advantage |
|---|---|---|---|
| £30,000 | 83.7% | 88.5% | 4.8 pts |
| £50,000 | 79.0% | 84.0% | 4.9 pts |
| £80,000 | 71.2% | 79.5% | 8.3 pts |
| £120,000 | 63.5% | 76.3% | 12.8 pts |
| £200,000 | 58.9% | 71.1% | 12.2 pts |
Swiss federal tax has a low top marginal rate and an average-rate ceiling, and cantonal scales are flat by European standards. The UK meanwhile tapers the personal allowance away above £100,000 at an effective 60% marginal rate. The two curves are diverging precisely where senior salaries sit.
The canton is worth more than most promotions
The same CHF 130,800 salary, three cantons, nothing else changed.
| Canton | Keeps | Net a year |
|---|---|---|
| Zug | 81.4% | CHF 106,483 |
| Zurich | 76.3% | CHF 99,805 |
| Geneva | 72.6% | CHF 94,989 |
Zug to Geneva is CHF 11,494 a year on an identical salary. Communal rates vary within a canton as well, so the address matters below the cantonal level too. If two Swiss offers are close on salary, the canton may well decide it.
Health insurance is not in these numbers, and it is not small
Swiss health cover is mandatory but bought privately, with premiums paid per person rather than deducted from payroll. It therefore does not appear in any of the percentages above. For a family it is a substantial monthly cost and it narrows the apparent Swiss advantage considerably. UK National Insurance has healthcare funding built in, so comparing the two payslips without adjusting for this overstates Switzerland's lead. Our guide to LaMal covers what to budget.

Swiss packages are commonly quoted across 13 payments rather than 12. Confirm whether an annual figure already includes the 13th before comparing, because the difference is about 8%.
How these figures were produced
PayMetric Labs' own calculations with our UK and Swiss tax engines at 2026 rates, using the federal scale with its average-rate ceiling, the cantonal tariff for each canton shown and employee social contributions, for a single taxpayer aged 35 with no church tax. Mandatory health insurance premiums, Pillar 3a contributions and the 13th month payment are excluded, as are UK pension contributions and student loan.

Frequently asked questions
Does the UK or Switzerland leave you with more?
Switzerland, at essentially every salary, and the advantage widens as you earn more. At the equivalent of £50,000 a Zurich employee keeps 84.0% of gross against 79.0% in the UK. At £120,000 it is 76.3% against 63.5%, a gap of 12.8 percentage points.
Why does the gap widen rather than narrow?
Because Swiss rates rise gently while the UK's rise sharply. Swiss federal tax has a low top marginal rate and an average-rate ceiling, and cantonal scales are relatively flat by European standards. The UK meanwhile tapers the personal allowance away between £100,000 and £125,140 at an effective 60% marginal rate. The two systems are moving in opposite directions exactly where senior salaries sit.
How much does the canton matter?
Nearly as much as the country. On the same CHF 130,800 salary, an employee keeps 81.4% in Zug, 76.3% in Zurich and 72.6% in Geneva. That is an 8.8 point spread from the canton alone, against a 12.8 point gap between Zurich and the UK. Choosing the canton is close to being as consequential as choosing the country.
Is Swiss health insurance a tax?
No, and leaving it out of a comparison is the biggest single error people make. Swiss health insurance is mandatory but privately purchased, with premiums paid per person rather than as a payroll deduction, and it does not appear in the percentages on this page. For a family it is a substantial monthly cost that materially narrows the apparent Swiss advantage. UK National Insurance, by contrast, has healthcare funding built into it.
What is Quellensteuer and will it apply to me?
It is withholding tax deducted at source, and it applies to most foreign nationals without a C permit. Rather than filing and paying afterwards, your employer withholds a cantonal tariff directly. The amount broadly tracks the ordinary calculation, but the mechanics and the correction process differ, and above certain income levels you must file a return anyway.
Does Switzerland pay a 13th month salary?
Commonly, though it is contractual rather than statutory. A Swiss package is often quoted as 13 payments, so a monthly figure multiplied by 12 understates it by around 8%. Always confirm whether a quoted annual figure already includes the 13th payment before comparing it against a UK salary.
How reliable is the currency conversion here?
Treat it as illustrative and check the live rate. The percentages are the durable part, because the share of gross you keep does not depend on the exchange rate. The rate used is stated and dated beside the cash table above, and comes from the European Central Bank's daily reference rates.
What does this comparison leave out?
Mandatory health insurance premiums, which are a real and large Swiss cost outside payroll. Pillar 3a contributions, which are deductible and a significant Swiss planning lever. Church tax, which is avoidable. Communal rates, which vary within a canton as well as between cantons. UK pension salary sacrifice. And the Swiss cost of living, particularly rent, which absorbs a meaningful part of the advantage.
Figures are PayMetric Labs' own calculations using our UK and Swiss tax engines at 2026 rates, for a single taxpayer aged 35 with no church tax, in the canton shown, against a single UK taxpayer with no pension contributions or student loan. Mandatory health insurance, Pillar 3a and the 13th month payment are excluded. Currency conversions use £1 = CHF 1.0925, European Central Bank reference rates, 23 September 2026 and will drift.
