A Wealth Manager’s Guide to Cross-Border Taxation, Social Security, and Structural Pitfalls.
Moving to Switzerland while retaining your UK employment requires precise structural planning.
This guide explains how physical presence triggers Swiss tax residency and outlines the specific employment arrangements necessary to maintain compliance across both jurisdictions.
Imagine an executive we’ll call David. David has spent fifteen years climbing the ranks at a London-based fintech firm. When his spouse is offered a career-defining role in Zürich, David is thrilled. He approaches his UK employer with a seemingly simple pitch: “My role is fully remote. I’ll keep my UK contract, pay my UK taxes, and work from my new apartment overlooking the Limmat. Nothing changes for the company.”
The company agrees, David packs his bags, and the move is made.
Six months later, David’s employer receives an inquiry from the Swiss Federal Social Insurance Office demanding retroactive employer contributions, while David faces a Swiss tax assessment on his global income that his UK PAYE deductions failed to account for. What seemed like a seamless remote-work arrangement rapidly transforms into an expensive compliance web.
As cross-border wealth managers, we see variants of David’s story constantly. The desire to pair a high UK salary with the unparalleled quality of life in Switzerland is highly attractive. However, moving your physical body across borders while leaving your employment structure behind triggers deep friction between two distinct regulatory and fiscal systems.
Here is what you actually need to know to navigate this transition safely.
Before making the move, both you and your employer must understand the legal parameters of cross-border employment. This guide explains:
The short answer is yes, but not under a standard UK employment framework.
Following Brexit, UK nationals no longer benefit from the EU/EFTA Agreement on the Free Movement of Persons. If you do not already hold a valid Swiss residence permit (such as a B or C permit) through family reunification or dual EU citizenship, moving to Switzerland as a third-country national to work remotely for a foreign employer is incredibly difficult.
Swiss immigration law under the Federal Act on Foreigners and Integration prioritizes local and EU/EFTA talent.To obtain a work permit, a Swiss employer must generally prove they cannot find a suitable candidate within Switzerland or the EU, and the applicant must meet strict professional quota criteria.
If you already have the legal right to reside in Switzerland (e.g., your spouse has a Swiss work permit), you are permitted to live in the country. However, how you work for your UK employer must be heavily restructured to comply with local laws.
Switzerland determines tax residency based on two primary factors:
Once you are deemed a Swiss tax resident, Switzerland asserts its right to tax your worldwide income and worldwide wealth. This includes your UK salary, investment portfolios held in London, and any UK real estate.
Conversely, the UK determines tax residency through the Statutory Residence Test (SRT). The SRT is a mechanical, multi-tiered framework assessing the number of days you spend in the UK and the number of ties (such as accommodation, family, or substantive work) you retain there.
If you move to Switzerland mid-way through a UK tax year, you will need to determine if you qualify for Split Year Treatment. This splits the tax year into a resident part (where you are taxed on worldwide income) and a non-resident part (where you are only taxed on UK-sourced income).
Even if you successfully establish non-resident status in the UK, HMRC will still view employment income derived from duties physically performed within the UK as taxable.
A common misconception is that if you are paid in Sterling into a UK bank account and remain on UK payroll, the UK retains the primary right to tax your salary. This is fundamentally incorrect.
Under Article 15 of the UK-Switzerland Double Taxation Agreement (DTA), employment income is generally taxed in the country where the work is physically performed.
Physical Presence in Switzerland ➔ Work Performed on Swiss Soil ➔ Primary Tax Right to Switzerland
If you are sitting in an apartment in Zürich or Geneva executing your daily duties, that income is fully subject to Swiss cantonal and federal income taxes.
To prevent double taxation, your UK employer must submit a Form P85 to HMRC to obtain an “NT” (No Tax) PAYE code. This instructs the payroll department to stop deducting UK income tax from your salary. If you travel back to the UK for board meetings or client workshops, those specific days are classified as UK workdays and will remain taxable by HMRC, requiring a meticulous, day-by-day cross-border allocation.
While income tax can be divided or credited via the DTA, social security is strictly binary. You can only be covered by one country’s system at a time.
Under the reciprocal UK-Switzerland Social Security Agreement, if you live and work habitually in Switzerland, you must be affiliated with the Swiss social security system.
This creates a severe operational obstacle for your UK employer. An employer based outside of Switzerland who employs a Swiss resident is legally obligated to pay the employer’s share of Swiss social insurance contributions. For a UK company with no Swiss corporate entity, setting up local payroll and registering with a cantonal compensation fund (Ausgleichskasse) is often a compliance hurdle they are unwilling to clear.
Taxolution Advisory
To solve this, three primary paths exist:
Employment Structure | Operational Mechanism | Best For |
ANobAG Status | Arbeitnehmer ohne beitragspflichtigen Arbeitgeber (Employee without a contributing employer). The employee formally agrees to pay both the employee and employer shares of Swiss social security, rolling the total cost into their UK gross salary contract. | Long-term senior staff and executives with cooperative employers. |
Employer of Record | A third-party Swiss agency legally employs you locally and invoices your UK firm for your salary plus a management fee. | Mid-level roles where the UK employer prefers zero administrative burden. |
Corporate Subsidiary | The UK firm establishes a formal Swiss branch or GmbH to employ you directly under Swiss corporate law. | Companies planning wider commercial expansion into Switzerland. |
Do You Still Have Questions?
Technically, yes, but your UK employer faces a hidden corporate threat: The Permanent Establishment Risk.
If a UK company has a senior executive living in Switzerland who routinely negotiates contracts, manages teams, or signs off on corporate strategy from their home office, Swiss tax authorities can argue that the UK company has created a physical place of business on Swiss soil.
If a Permanent Establishment is successfully asserted, a portion of the UK company’s global corporate profits becomes subject to Swiss cantonal and federal corporate taxation. For this reason, legal departments inside UK firms frequently veto long-term remote work arrangements unless structural guardrails are firmly in place.
Leaving the UK impacts both your state and private pensions:
To receive the full UK State Pension, you need 35 qualifying years of National Insurance contributions. Once you stop paying UK NICs, your record pauses.
However, under the bilateral agreement, your Swiss insurance periods can be taken into account to meet the minimum qualifying period, and you can often make voluntary Class 2 or Class 3 NIC contributions while abroad to maintain your UK entitlement at a very low cost.
You can generally leave your existing UK pension funds invested, where they will continue to grow tax-deferred under the protective umbrella of the UK-Swiss DTA. However, once you lose UK tax residency, your ability to make tax-relieved contributions to a SIPP or a UK corporate pension drops to zero after five years (and is limited to just £3,600 gross annually during those five years).
Furthermore, Swiss financial institutions will not automatically recognize your UK scheme for local tax deductions, meaning you will likely need to establish a Swiss Pillar 3a account to optimize your local tax planning.
Income tax is generally paid where the work is physically performed. If you are executing your daily duties from Switzerland, you will pay Swiss income tax. Your employer must submit a Form P85 to HMRC to obtain an “NT” (No Tax) PAYE code to stop your UK income tax deductions.
A standard UK employment contract fails to account for mandatory Swiss social security obligations, local employment laws, and cantonal health insurance requirements. Your employer must implement a compliant structure, such as ANobAG status, an Employer of Record, or a formal Swiss subsidiary.
You retain your existing qualifying years. You can continue building your UK State Pension record by making voluntary Class 2 or Class 3 National Insurance contributions while living abroad.
Your existing SIPP can remain invested and will continue to grow tax-deferred. Once you lose UK tax residency, your ability to make new tax-relieved contributions becomes heavily restricted.
Relocating to Switzerland while retaining UK employment involves complex tax, immigration, corporate compliance, and social security overlaps. Moving across borders without updating your employment structure exposes you to unexpected tax assessments and creates severe compliance liabilities for your employer.
Navigating these jurisdictions requires precise structural planning to protect your personal wealth and shield your company from foreign corporate tax risks.
