Since the UK’s departure from the European Union, cross-border relocation planning has become a more frequent topic for British entrepreneurs, founders and high earners. Andorra, a microstate in the Pyrenees, offers a competitive and transparent tax framework, including a personal income tax system with a general rate of 10 %, no general wealth tax, and no general inheritance tax comparable to those existing in several European jurisdictions.
For UK business owners who have built significant value in their companies and are evaluating exit, succession or liquidity events, these features can be a material consideration. However, obtaining Andorran tax residency requires more than obtaining a residence permit. It requires genuine relocation, a coherent break from UK tax residence under the UK Statutory Residence Test, compliance with Andorran immigration requirements, and ongoing consistency between personal, family, economic and reporting circumstances.
Augé Legal & Fiscal, based in Andorra, advises UK nationals on establishing Andorran tax residency, covering immigration, pre-departure tax planning, coordination with UK advisers, and ongoing Andorran compliance.
How Andorran personal tax compares to UK rates
For the 2026/27 tax year, the UK applies income tax in England, Wales and Northern Ireland at 20 % on basic-rate income, 40 % on income above the higher-rate threshold, and 45 % on income above £125,140. The standard personal allowance is £12,570, but it is gradually withdrawn for income above £100,000 and is fully withdrawn once income reaches £125,140. Scotland applies different income tax bands and rates.
Employee National Insurance Contributions are separate from income tax. For 2026/27, employee Class 1 National Insurance is generally charged at 8 % between the primary threshold and the upper earnings limit, and 2 % above that limit.
Andorra’s personal income tax structure is significantly different. The Andorran IRPF applies a general rate of 10 %, combined with a personal allowance and certain reductions or tax credits. In practical terms, the first €24,000 of general taxable income is usually exempt, income between €24,000 and €40,000 can result in an effective 5 % rate, and income above €40,000 is generally subject to the 10 % reference rate.
There is no general wealth tax in Andorra, no general inheritance tax comparable to the UK inheritance tax regime, and dividends received from Andorran companies may be exempt from Andorran personal income tax when the relevant legal conditions are met. The comparison with the UK must nevertheless be modelled carefully, because the final tax position depends on the nature of the income, the timing of distributions or disposals, National Insurance, dividend taxation, capital gains tax, treaty relief and anti-avoidance rules.
How the UK Statutory Residence Test works on departure
Establishing Andorran tax residency does not automatically end UK tax residency. The UK Statutory Residence Test, introduced by the Finance Act 2013, determines residence by reference to days spent in the UK, automatic UK tests, automatic overseas tests and the sufficient ties test.
To cease being UK resident, a taxpayer must analyse the position for the relevant UK tax year, taking into account the split year rules where applicable. The number of days that can be spent in the UK depends on the taxpayer’s historic residence status, the availability of a UK home, family ties, work ties, accommodation ties, 90-day ties and the amount of time spent in the UK in previous years. There is no single universal “safe” threshold that applies to all departing taxpayers.
HMRC scrutinises changes of residence where the individual retains meaningful UK connections, such as an available UK home, family members remaining in the UK, continuing UK workdays, directorships or management functions, or a day count close to the relevant SRT limits. Professional advice from a UK tax adviser working alongside an Andorran specialist is essential before formalising any departure.
Andorra’s residency categories for UK nationals
Post-Brexit, UK citizens are third-country nationals for Andorran immigration purposes and must meet the general conditions applicable to non-EU, non-EEA applicants.
Andorra offers several routes that may be relevant to UK business owners. Active residency applies to individuals working in Andorra, either as employees of an Andorran entity or as self-employed workers registered with the CASS. For entrepreneurs, active residency may also involve participation in an Andorran company, effective management functions in the Principality, and compliance with the specific requirements applicable to self-employed or company-director profiles.
Residence without gainful activity, often referred to as passive residency, is aimed at individuals with sufficient financial means who do not intend to carry out a professional or commercial activity in Andorra. For 2026, the investment requirement should be checked carefully against the current immigration rules. Recent guidance published by Augé Legal & Fiscal refers to a general minimum investment of €1,000,000, reducible to €400,000 where the investment is channelled through the Fons d’Habitatge, together with a non-refundable AFA payment of €50,000 for the main applicant and €12,000 per dependent.
Residence permits are renewable and require documented physical presence in Andorra. Passive residents are generally expected to spend at least 90 days per year in the Principality, but this administrative requirement should not be confused with Andorran tax residency, which generally depends on spending more than 183 days in Andorra during the calendar year or having the centre of economic or personal interests in the country.
The process involves submitting recent, duly legalised or apostilled documentation, with translations into a language accepted by the Andorran authorities where required.
What HMRC looks for when challenging a claimed residence change
HMRC scrutinises residence changes where the facts do not align with the claimed position. Common risk factors include maintaining a UK home available for use, family members remaining in the UK, children continuing in UK schools, professional activities or management functions continuing substantially in the UK, and UK day counts that approach or exceed the relevant Statutory Residence Test thresholds.
For Andorra specifically, travel between the UK and the Principality remains relatively accessible, which increases the practical risk of accumulating UK days inadvertently. This risk should be managed through a disciplined travel calendar and evidence trail.
Documenting Andorran presence through travel records, accommodation evidence, utility bills, healthcare registration where applicable, local banking activity, card transactions, professional activity, community involvement and evidence of social life in the Principality is standard practice for individuals whose residence change is likely to attract scrutiny. The quality and consistency of this documentation often determines the outcome of any HMRC enquiry.
Practical considerations for UK business owners
For UK entrepreneurs who hold shares in UK companies, the interaction between UK corporate tax, dividend taxation, capital gains tax, inheritance tax and the new Andorran personal tax residency needs careful mapping.
UK-source dividends are not generally subject to UK withholding tax when paid by ordinary UK companies. However, they may remain relevant for UK tax purposes depending on the individual’s residence status, the timing of the distribution, the application of split year treatment, anti-avoidance rules and the UK-Andorra Double Taxation Convention.
UK capital gains tax may continue to apply to certain UK-situated assets, particularly UK land and property-rich assets, even when the individual is non-UK resident. Temporary non-residence rules may also bring gains or distributions back within the UK tax net if the individual returns to the UK within the relevant period.
Planning the timing of dividend distributions, share disposals and other realisation events relative to the date of departure from UK residence can have significant tax implications and should be addressed in pre-departure advice. The realistic timeline from initial planning to a stable Andorran tax residence position is often several months and may extend to six to twelve months where immigration, banking, documentation, relocation and UK departure planning are all involved.
The ongoing obligations once residency is established
Andorran tax residents file an annual personal income tax return with the Andorran tax authority where they meet the relevant filing thresholds and reporting obligations. The return covers worldwide income for individuals who meet the Andorran definition of fiscal residence.
Andorra applies the Common Reporting Standard and exchanges financial account information automatically with participating jurisdictions, including the UK. This means that financial accounts held in Andorra by reportable persons may be disclosed to the relevant foreign tax authorities under CRS procedures.
Andorran residents who retain assets in the UK remain subject to UK rules on those assets where UK domestic law and the UK-Andorra Double Taxation Convention allocate taxing rights to the UK. Rental income from UK property, for example, generally continues to be taxable in the UK under the non-resident landlord regime, subject to treaty analysis and relief from double taxation where applicable.
Managing these cross-border flows requires ongoing coordination between the adviser in the UK and the Andorran firm handling local compliance.
