United Kingdom vs Switzerland taxes

Switzerland and the United Kingdom are both expensive, high-capacity European bases. The tax difference is design, not a simple “low versus high” label.

In Switzerland the bill is built from three layers. Direct federal tax sits under cantonal and communal income tax. Wealth tax is annual and local. Inheritance and gift tax, where they exist, are also cantonal. Move from a high-tax city commune to a low-tax suburban commune and the same salary and balance sheet can change by a material percentage. Private movable capital gains are usually outside income tax, which is why securities investors often prefer Switzerland to the UK’s 18% and 24% individual CGT rates from 6 April 2026. Company tax follows the same geography: 8.5% federal plus local profit tax, often below the UK’s 25% main rate, with a 15% minimum-tax overlay for large multinational groups.

The UK is flatter and heavier. Income tax reaches 45% (48% in Scotland). Employment also carries National Insurance. VAT is 20% against Switzerland’s 8.1%. There is no UK net wealth tax, which can favour an asset-rich, low-yield household that would otherwise file a Swiss wealth return every year. The UK’s succession cost is the reverse of that advantage: 40% inheritance tax, and from 6 April 2025 a long-term UK residence test that can pull worldwide assets into the charge.

A new UK resident who has been non-UK tax resident for at least ten consecutive years may claim the four-year foreign-income-and-gains regime. That is a time-limited income and gains relief, not a substitute for Swiss canton shopping, and it does not cancel IHT once long-term residence is reached. Banking, work permits and actual days in the canton still decide whether the Swiss numbers are real.
