Moving to Switzerland from the United Kingdom

Why Britons are looking at Switzerland in 2026

For most of the last forty years, a British taxpayer with international income or significant capital could quietly arrange their affairs around the remittance basis. From 6 April 2025, that regime ended. The remittance basis was abolished, the concept of domicile was stripped out of the income-tax, capital-gains, and inheritance-tax codes, and the system pivoted to one organised around residence. The change is set out in HMRC's Changes to the taxation of non-UK domiciled individuals and the supporting Residence, Domicile and Remittance Basis Manual.

The replacement is the Foreign Income and Gains (FIG) regime. A new arrival who has not been UK tax resident in any of the previous ten tax years can claim exemption from UK tax on foreign income and gains for the first four years of UK residence. That is the entire generosity of the new system. After four years, the arrival is taxed on the worldwide arising basis like everyone else. The historically long planning runways (fifteen years before deemed domicile, occasionally indefinite for those who could maintain a foreign domicile of origin) are gone.

The non-dom change is the headline, but it is not the only push factor. Four others matter to the decision.

Two other factors sit below the tax headlines but shape the same decision. First, the slow regulatory drift since 2020 (divergence from EU financial services rules, the FCA's tightening of promotion and listing regimes, the failure of any meaningful replacement for passporting) has made London a more cumbersome base for cross-border financial professionals than it was in 2015. Second, stamp duty land tax on a £2M family home in London now sits at the top of the schedule (12% above £1.5M plus the 5% additional-property surcharge where applicable), and the Autumn 2024 changes to non-residential property surcharges added further friction. None of this is a tax change in the conventional sense; it is the cumulative cost of running a senior career and a household in the UK in 2026.

Underneath the tax arithmetic sits a slower story. The top marginal rate of income tax plus employee NIC sits near 47% for additional-rate taxpayers; the personal allowance tapers to zero between £100,000 and £125,140, producing a 62% marginal trap on that £25K band. Per-capita public-service quality has slipped on most measurable axes since 2019. Sterling has lost meaningful real ground against the Swiss franc since Brexit. None of these is decisive on its own. Stacked, they explain why the question many readers are arriving with in 2026 is no longer whether to look at Switzerland, but where in Switzerland and on what timing.

02

What Switzerland actually is, in tax terms

Switzerland is a federal state with three layers of personal income tax: the direct federal tax (Bundessteuer / impôt fédéral direct), the cantonal tax, and the communal tax. Twenty-six cantons. Roughly 2,120 communes. The federal layer is uniform across the country and capped at 11.5% at the top bracket. The cantonal and communal layers are not. They are the entire reason Swiss tax planning exists as a discipline.

For a British reader, the most useful single mental shift is this: Switzerland taxes on residence, not on domicile, and it taxes the household at the level of the commune you happen to live in. The choice of canton, and within that the choice of commune, is the largest controllable variable in your Swiss tax bill. The same household, on the same income, can pay roughly twice the tax in Geneva that it pays in Zug. This is the headline number people quote and it is broadly true.

Beyond the ordinary canton system, Switzerland operates a separate regime for wealthy foreigners who do not work in the country: the forfait fiscal (lump-sum taxation, sometimes called expense-based taxation). Rather than being taxed on worldwide income, the household is taxed on a deemed base derived from their Swiss living expenses. The federal floor is the higher of seven times the annual rent or rental value of the residence, or a statutory minimum that is currently CHF 434,700 of deemed taxable income; cantons may and do impose higher floors. The federal rules are set out in the ESTV guidance on Besteuerung nach dem Aufwand; a useful cross-canton summary is in KPMG's Clarity on Swiss Taxes.

Five German-speaking cantons have abolished the forfait at cantonal level: Zurich (2010), Schaffhausen, Appenzell Ausserrhoden, Basel-Stadt and Basel-Landschaft. The federal layer still applies in those cantons, but the regime in practice requires a canton that retains it. The cantons that remain attractive to forfait arrivals — Vaud, Valais, Geneva, Ticino, Bern, Graubünden, Lucerne, Fribourg, Schwyz, Zug and others — each set their own minimum, and Geneva in particular operates at a substantially higher floor than the federal minimum.

One feature of the Swiss system that surprises arriving Britons is how much of everyday administration runs at the commune level rather than the canton or federal level. Your residence permit is issued by the canton but registered with the commune. Your communal tax rate is set by your commune within parameters set by the canton. Your school catchment, your refuse collection, your building permits, and your voting register all sit with the Einwohnerkontrolle of the commune. Moving thirty minutes across a cantonal border is a different administrative act from moving three streets within the same commune. For a British arrival used to a unitary state with HMRC, the Home Office, and a local council operating on a single tier, the mental adjustment is non-trivial but quickly intuitive. The federal government handbook for new residents is published at ch.ch: official information for newcomers.

The forfait is not a loophole. Successful applicants accept that their Swiss tax bill will run from the high six figures into seven, depending on canton and lifestyle, and that they will not work in Switzerland. For a high-net-worth Briton whose UK alternative is now a worldwide-arising basis with a ten-year IHT tail, the trade is often arithmetically attractive. But it is a structurally different decision from an ordinary cantonal move, and it needs a Swiss tax adviser before, not after, the application.

The social contract trade-off

The Swiss state is small at the federal level and dense at the communal level. What Britain provides through universal entitlement funded out of general taxation, Switzerland provides through mandated private contracts, communal participation, and an expectation that you will integrate. Three trades matter most.

The NHS is replaced by mandatory private health insurance (KVG / LAMal). Every Swiss resident must purchase basic health insurance from a regulated private insurer within ninety days of arrival; the catalogue of covered services is set federally and is substantively broad. Premiums are not income-linked. A reasonably healthy adult in 2026 pays CHF 350–700 per month for basic cover, depending on canton, deductible chosen, and insurer. A family of four typically falls in the CHF 12,000–22,000 per year range before any supplementary (VVG) cover. Premiums vary by canton and commune; the federal regulator publishes the official survey at Priminfo. The system is good; it is also expensive in a way the NHS is not.

The free state school is replaced by a strong local-language public school. Swiss public schools are well-resourced and academically serious, but instruction is in the local language (Swiss German, French, Italian, or Romansh) from day one. A British family arriving with a nine-year-old who speaks no German has three options: place the child in the local school and accept a steep adjustment year; place them in an international school (Zurich International School, Inter-Community School, ICS Zurich, Institut Le Rosey, École Internationale de Genève, and others) at CHF 25,000–45,000 per child per year; or use a transition language school for one or two years and then move into the public system. Most arriving families with children under eight send them to the public school. Most with children over twelve do not.

The welfare safety net is replaced by a contributory social system.Switzerland's old-age, disability, and survivor insurance (AHV / IV / EO) is mandatory, contributed to by both employer and employee, and pays out on the basis of years of contribution. Unemployment insurance (ALV) is available to those who have contributed for at least twelve of the preceding twenty-four months. Welfare-of-last-resort exists at the cantonal and communal level (Sozialhilfe / aide sociale), but is means-tested, time-limited in practice, and consequential: claiming it has historically been a factor in residence-permit renewals for non-citizens, and the policy framework is set out in the SKOS guidelines. The British assumption that the state catches you if your career falters is not the Swiss assumption. The Swiss assumption is that your commune, your employer, and your accumulated contributions do.

A fourth trade is less talked about but matters for British families specifically: the apprenticeship-versus-university pathway. Roughly two thirds of Swiss school-leavers enter vocational apprenticeships (Berufslehre / formation professionnelle) at sixteen rather than the academic Matura track. The system is well-regarded; it is also a very different cultural assumption from the British default that university is the universal aspiration. Families who arrive assuming their children will follow a UCAS-style route should understand that the Swiss state schools are organised around a sorting decision at age twelve to thirteen, and that the apprenticeship track is the modal outcome, not a fallback. The federal overview is at SBFI's vocational and professional education and training.

Around these three are the smaller civic expectations that British arrivals find either congenial or grating, with no middle ground. Recycling is enforced at the bag level. Sunday is observably quiet and lawn-mowing is restricted in many communes. Apartment buildings run on internal Hausordnung rules that are taken seriously. The unwritten obligation to learn at least functional German (or French or Italian) is not negotiable in the long run, even if your job is in English and your colleagues are international. The British tendency to treat civic friction as optional has a short shelf life in Switzerland. Most who stay come to enjoy the structure; some never adjust to it and leave within three years.

What it actually costs versus what you actually keep

The honest comparison is not at the headline marginal rate. The UK additional rate (45% income tax, plus 2% employee NIC above the upper earnings limit) sits in a similar zone to the highest combined Swiss cantonal rates in places like Geneva or Vaud. The structural differences sit elsewhere: Switzerland does not tax most private capital gains, taxes worldwide wealth modestly at the cantonal level, and does not impose inheritance tax federally (cantonal IHT exists but in most cantons exempts a surviving spouse and lineal descendants). The interesting differences appear once you trace specific personas through their actual numbers.

Three illustrative households below. None of these is a substitute for advice from a Swiss tax adviser; all of them can be re-run with your own numbers in the cross-country tax calculator.

Housing. Switzerland is a country of renters: roughly 60% of households, the highest rate in Europe. The reason is partly cultural and partly tax-structural: Swiss homeowners are taxed on an imputed rental value (Eigenmietwert / valeur locative) of their primary residence, which is added to taxable income; the deduction for mortgage interest partially offsets this, but the net effect is a structural incentive to maintain a substantial mortgage and to consider Pillar 3a indirect amortisation rather than principal paydown. The eigenmietwert is currently under reform (federal legislation passed in 2025 to abolish it from 2028, alongside a curtailment of the mortgage interest deduction), and the system British arrivals will encounter through 2027 may differ from the one they live under in 2030. For most UK arrivals in 2026, the practical advice is the same: rent for the first 24–36 months, understand the local mortgage market before buying, and run the specific household numbers through our mortgage affordability calculator once you are ready.

One number that does not appear in the persona tables but matters for monthly cash flow: Swiss VAT is 8.1%versus the UK's 20%. On large discretionary spend — cars, furnishings, renovations, restaurants for those who eat out often — the indirect-tax difference compounds. The Swiss figure is published by the federal authority at ESTV (VAT rates Switzerland). Against this, Swiss labour-intensive services (handymen, cleaners, childminders, electricians) cost meaningfully more per hour than UK equivalents, so the indirect-tax saving and the labour-cost premium partially offset.

Across all three, the pattern is consistent. Switzerland is not dramatically better than the UK on ordinary employment income at the CHF 200–300K range. Once you net out the cost of mandatory health insurance and the higher cost of groceries and services, you keep perhaps 10–20% more cash. Switzerland is structurally and meaningfully better than the UK on the treatment of capital, on inheritance, and on the marginal rate of additional income above £125K. The decision is therefore not really “will I take home more on my salary”; it is “what does the rest of my financial life look like in five, ten, and twenty years”.

The integration timeline, honestly

Since Brexit, UK nationals have been third-country citizens for the purposes of Swiss immigration law. The EU/EFTA free-movement framework does not apply. In practice, that means a Briton entering Switzerland needs one of: an employer sponsoring a B-permit against quota; a residence permit via forfait fiscal; family reunification; or self-employment authorisation, which is granted sparingly. The general framework is in the SEM (State Secretariat for Migration) residence pages.

Within the third-country framework, the distinctions that matter day-to-day are: L-permit (short-term, up to twelve months, generally not renewable on quota grounds); B-permit (annual residence, renewable, the workhorse for working arrivals); C-permit (settlement, granted after roughly ten years of continuous residence for third-country nationals); and Ci-permit (issued to family members of international-organisation staff). UK nationals working for an international employer at sufficient seniority are routinely sponsored on B from the outset, but the federal quota for non-EU/EFTA B-permits is finite and is allocated cantonally, which is why a competing job offer in, say, Geneva may move faster or slower than the same role in Zug depending on where each canton stands against its annual quota in any given quarter. The current quota framework is published by SEM's third-country employment page.

The UK-specific pension issue. Switzerland was removed from the QROPS list in 2017, after Swiss pillar regulations were judged not to meet HMRC's definition of a qualifying recognised overseas pension scheme. A transfer of a UK pension to a Swiss vehicle therefore triggers the overseas transfer charge (OTC) of 25% unless a narrow exemption applies; the legislative position is set out in HMRC's Pensions Tax Manual PTM102200. The Autumn 2024 Budget narrowed the previous EEA / Gibraltar exemption further, so transfers to those jurisdictions now also generally attract the OTC unless the saver is resident in the same jurisdiction as the receiving scheme. For most British movers to Switzerland, the practical conclusion is to leave the UK pension where it is and draw it on arrival under the UK-Swiss double tax treaty, rather than transfer. For those with very large UK pension pots, the advisable course is a full pre-move pension review with a UK-licensed adviser.

The UK-specific CGT and IHT issues. Two rules need to be understood before — not after — a move:

• The five-year temporary non-residence rule.If you leave the UK and return within five complete tax years, gains you realised while non-resident on assets you held at departure are brought back into UK CGT in your year of return; see HMRC's RDRM12600. If there is any realistic chance you may return to the UK within five years, the planning case for selling assets immediately after the move weakens substantially.
• The ten-year IHT tail. A long-term UK resident who leaves does not immediately escape IHT on worldwide assets. The tail extends for up to ten yearsafter departure for those who were resident for 20+ years; shorter for shorter residence histories. The detail is in HMRC's residence-based IHT guidance cited above. For an IHT plan to work, the timing of the move and the structure of the estate matter as much as the destination.

One process detail that recurs in UK arrivals: the Swiss household tax filing. The first calendar year of Swiss residence is filed in the spring of the following year (filings typically open in February, with extensions available to autumn). For those moving from PAYE, the shift to an annual self-assessment-style filing is unfamiliar but the document burden is light: the Swiss authorities already receive most banking and employer data. The complication is usually on the UK side: a split-year treatment claim for the year of departure, and the question of whether any UK income or gains arose between departure and the formal break in UK residence. HMRC's RDR3 / Statutory Residence Test guidance is the canonical reference.

For long-term saving inside Switzerland, the equivalent of the ISA wrapper is the third pillar (Pillar 3a), capped at CHF 7,258 for 2026 if you also pay into a workplace pension (Pillar 2), or up to CHF 36,288 for the self-employed without Pillar 2 (capped at 20% of net earned income). The mechanics, including how a Pillar 3a contribution interacts with your cantonal marginal rate, are in our Pillar 3a calculator.

Decision tree and next steps

Most British readers arriving on this page fall into one of four categories. The right next step is different for each.

Three concrete next steps that hold regardless of category:

1. Model your actual numbers. The cross-country tax calculator compares the UK position against your candidate canton at your actual income, household structure, and wealth. The output is indicative, not advice, but it sets the order of magnitude.
2. Engage a UK-Swiss tax adviser before disposing of UK assets. Most disasters in this space come from well-intentioned pre-move asset sales that miss the temporary non-residence rule, the IHT tail, or the substantial-shareholding implications. A two-hour consultation with someone qualified in both jurisdictions is the highest-leverage spend in the entire project.
3. Pick the commune, not just the canton. Visit twice if you can — once in summer, once in winter — and walk the streets of the specific commune you are considering. Switzerland integrates at the commune level. The brochures integrate at the canton level. The mismatch is the single largest source of early-return regret.

For parallel country views, see our companion guides: Moving to Switzerland from France (the article 167 bis exit tax and the post-2015 inheritance gap), Moving to Switzerland from Germany (the Wegzugsteuer and the German treaty grip), Moving to Switzerland from Italy (the clean-exit case — no individual exit tax), and Moving to Switzerland from Norway (the wealth-tax and exit-tax arithmetic). The mechanics differ. The discipline of running primary-source numbers before signing a lease does not.
