Andorra Tax Residency: What Spanish Residents Need to Know Before They Move

Andorra is frequently presented as a straightforward tax solution for Spanish business owners and high-income professionals: low personal income tax (IRPF equivalent at a maximum of 10%), no wealth tax, no inheritance or gift tax, a compact territory on the Spanish border. Online forums and unregulated 'consultants' make it sound simple. The reality that the Spanish Tax Agency (AEAT) presents is considerably more demanding. Spain is one of the most aggressive jurisdictions in the EU in challenging the fiscal residency of taxpayers who relocate to low-tax countries while maintaining family, social and business ties in Spain. The conditions for a residence change to be valid against the AEAT are strict, the inspection risk is real, and the consequences of getting it wrong — Spain can claim 5 years of back taxes plus penalties — are severe.

How we work

From first contact to case completion

  1. Feasibility Analysis

    We assess your current situation: Spanish ties (family, property, business interests, board positions), volume of income and its sources, Spanish-held assets that would trigger exit tax, and the realistic number of days you can spend in Andorra. We give you a frank assessment of whether an Andorran residency is defensible.

  2. Treaty and Exit Tax Structuring

    We analyse the Spain-Andorra Double Tax Treaty (in force since 26 February 2016), the exit tax position under Article 95 bis LIRPF (applies to unrealised gains on participations above 25% or €1M, or to total assets above €4M), and the structuring options to manage those liabilities.

  3. Documentation and Compliance

    If you proceed with the residency change, we establish the documentation protocol: Andorran passive or active residency requirements, Form 030 deregistration in Spain, Spanish Form 720 for foreign assets, Andorran IRPF registration, evidence of physical presence (utility bills, medical records, flight logs), and ongoing monitoring.

  4. Ongoing Defence and Monitoring

    The first four years are the highest-risk period for AEAT challenge. We monitor your position, manage any AEAT information requests, and coordinate with Andorran advisers on the local compliance side.

The problem

Andorra is frequently presented as a straightforward tax solution for Spanish business owners and high-income professionals: low personal income tax (IRPF equivalent at a maximum of 10%), no wealth tax, no inheritance or gift tax, a compact territory on the Spanish border. Online forums and unregulated 'consultants' make it sound simple. The reality that the Spanish Tax Agency (AEAT) presents is considerably more demanding. Spain is one of the most aggressive jurisdictions in the EU in challenging the fiscal residency of taxpayers who relocate to low-tax countries while maintaining family, social and business ties in Spain. The conditions for a residence change to be valid against the AEAT are strict, the inspection risk is real, and the consequences of getting it wrong — Spain can claim 5 years of back taxes plus penalties — are severe.

Our solution

BMC analyses the feasibility of an Andorran tax residency for each client individually: the effective presence requirements, the treaty position, the exit tax implications, the documentation strategy and the realistic AEAT challenge risk. We do not sell residence changes as guaranteed solutions. We tell you what is achievable, what is risky and what the cost of each path is — so you can make an informed decision.

10%
Maximum IGEC (Andorran personal income tax) rate — compared to 47% in Spain at the top bracket
183 days
Minimum physical presence required in Andorra each calendar year for effective tax residency
4 years
Minimum AEAT monitoring period after a declared residency change to a low-tax country (Art. 8.2 LIRPF)

We analysed the Andorra option for our principal shareholder. BMC's assessment was honest: the required physical presence was incompatible with his family situation in Spain. We found a more defensible international structure instead. It cost us nothing to know in advance.

CFO Spanish industrial group

Andorra is a popular destination for Spanish nationals considering a change of tax residence. The appeal is clear: a maximum personal income tax rate of 10%, no wealth tax, no inheritance tax, geographical proximity to Spain and a high standard of living. But between the attractive headline and a legally valid, AEAT-defensible residency change lies a demanding set of requirements that many advisers understate.

What “tax residency” actually means in Spanish law

Spain’s General Tax Law (LGT) and the Personal Income Tax Law (LIRPF) establish that a taxpayer is a Spanish tax resident if:

  1. They spend more than 183 days in Spain in a calendar year (counting authorised absences)
  2. Spain is the principal base or centre of their economic activities or interests
  3. Their spouse and minor children reside habitually in Spain (rebuttable presumption)

The AEAT does not require all three conditions — any one of them is sufficient. This is the critical point: a Spanish business owner who moves to Andorra but whose spouse and children remain in Spain, who continues to manage a Spanish company, and who returns to Spain every weekend is technically a Spanish tax resident regardless of their Andorran registration.

The 183-day rule: the AEAT’s enforcement tools

Meeting the 183-day requirement in Andorra means demonstrating physical presence in Andorra on at least 183 days of the calendar year. The AEAT has expanded its enforcement toolkit substantially:

  • Mobile phone location data requests (through operator cooperation agreements)
  • Credit card and bank transaction geo-location
  • Vehicle location through toll records and traffic cameras
  • Airport and border crossing records (Andorra’s land borders with Spain are monitored)
  • Social media activity analysis
  • Spanish medical, educational and leisure records

The AEAT has consistently succeeded in courts in challenging residency changes where the taxpayer’s actual daily life pattern was centred in Spain, regardless of the formal registration in Andorra or the number of days formally attributed to Andorra.

The exit tax: quantifying the cost of leaving

Before any residency change, Spanish taxpayers with material shareholdings or assets must quantify the exit tax exposure under Article 95 bis LIRPF. The tax applies where:

  • The taxpayer holds more than 25% of a company’s capital, or shares with a market value above €1M; or
  • Total unrealised gains across all assets exceed €4M

The charge is IRPF at savings-rate brackets (up to 28%) on the deemed gain as at the departure date. For moves to EU/EEA countries (Andorra has a tax information exchange agreement that qualifies it for the deferred payment regime), payment can be spread in equal instalments over five years — but guarantees must be provided if the total gain exceeds €10M.

For a Spanish entrepreneur with a 100% stake in a company valued at €5M and a tax base of €1M, the exit tax on departure is approximately €1.12M (28% × €4M unrealised gain). That amount either must be paid before departure or deferred over five years with appropriate security. It is not an obstacle to the residency change, but it is a material cost that must be known before the decision is taken.

A frank assessment

Andorran tax residency is achievable and legally valid for the right profile: a single individual (or couple without school-age children), whose business activities can genuinely be conducted remotely or from Andorra, who can credibly spend 183 days per year in Andorra, and who does not maintain a habitual family home in Spain. It is a poor solution for a married parent with children in Spanish schools, a director of an active Spanish operating company, or anyone whose daily life remains visibly centred in Spain.

BMC analyses each situation individually before making any recommendation. The cost of an AEAT challenge — back taxes for up to five years, interest and penalties — substantially exceeds the tax saving in most cases where the residency change is not genuinely substantiated.

Frequently asked questions

Andorra's personal income tax (IGEC, Impost General sobre la Renda de les Persones Físiques i Jurídiques) applies at a maximum rate of 10% on income above approximately €40,000. Income below €24,000 is exempt. Compared to Spain's top marginal rate of 47% at the state level (plus regional supplements that can push the combined rate above 50% in some communities), the difference is substantial. However, the effective saving only materialises if the Andorran residency is legally valid and defensible against the AEAT.
There are two routes. Passive residency requires: (a) investment of at least €600,000 in Andorran real estate or other qualifying assets; (b) a deposit of €50,000 with the AFA (Andorran financial regulator); (c) physical presence in Andorra for at least 90 days per year. Active residency (more common for professionals and business owners) requires: (a) registration of a genuine economic activity or employment in Andorra; (b) affiliation with the Andorran Social Security (CASS); (c) physical presence of at least 183 days per year in Andorra. Both routes require proof of genuine habitual residence: a leased or owned main home in Andorra, utility contracts in the resident's name, medical and banking registration.
The Double Tax Convention between Spain and Andorra entered into force on 26 February 2016. It follows the OECD Model and allocates taxing rights between the two countries on standard categories: employment income, dividends, interest, royalties and capital gains. Where a taxpayer has effectively changed residence to Andorra and meets the treaty residency test (habitual abode in Andorra, centre of vital interests), the convention prevents Spain from continuing to tax their worldwide income. Without a valid treaty position, Spain can assert jurisdiction over income from Spanish sources (which it can tax under IRNR in any case) and may assert continued residence under its domestic rules.
Article 95 bis LIRPF imposes an exit tax on taxpayers who cease to be Spanish tax residents and hold: (a) shares representing more than 25% of a company's capital, or shares with a market value above €1M; or (b) total assets with unrealised gains above €4M in aggregate. The exit tax charges IRPF at the savings rate (up to 28%) on the unrealised gain as if the assets had been sold on the day of departure. For moves to EU/EEA countries including Andorra (which has a tax information exchange agreement), payment can be deferred in instalments over five years, with guarantees if the gains exceed €10M. The exit tax can be a material cost and must be factored into any feasibility analysis.
The AEAT applies a range of criteria to establish that a declared change to Andorran residence does not reflect genuine habitual residence: frequency and duration of stays in Spain (mobile phone records, credit card usage, vehicle location data, airport records); continued residence of spouse and children in Spain; participation in Spanish companies as director or shareholder with active management functions; Spanish medical records, club memberships, school fees; ownership of principal home in Spain. The AEAT has specific inspection teams dedicated to monitoring residency changes and has successfully challenged numerous Andorra cases in the courts.
Yes, but with important constraints. Owning a property in Spain is not per se incompatible with Andorran tax residency — it is the pattern of use that matters. If the Spanish property is the de facto place where the taxpayer and their family live for most of the year, the AEAT will treat it as the principal residence regardless of the formal declaration. If the Spanish property is a secondary residence genuinely used for holidays or occasional visits, and the main home is demonstrably in Andorra, the position is more defensible. Rental income from Spanish properties continues to be taxed in Spain under IRNR (Non-Resident Income Tax) after the residency change.
Other jurisdictions used by Spanish nationals: Portugal (NHR regime, now reformed into the IFICI regime from 2024, with narrower eligibility); Malta (non-domicile status with reduced taxation on foreign income); UAE/Dubai (no personal income tax, 9% corporate tax from 2023); Gibraltar (territorial system); Cyprus (60-day residency option for EU residents). Each has different requirements, treaty coverage with Spain and AEAT challenge risk profiles. BMC analyses the full set of options for each client rather than recommending a single jurisdiction.
