Andorra is sold on proximity. It is two hours from Barcelona, the language of business is one a Spanish family already speaks, and the schools, the banks and the professional community are all within reach of a life that does not have to be dismantled. Those same features are why Andorran residence fails more often for Spanish families than for any other nationality.
The failure is rarely at the Andorran end. Andorra grants the permit, the family moves, the Andorran filings are made correctly. The failure is at the Spanish end, where a different authority applies a different test to the same facts and reaches a different answer. That the two tests are separate, and that only one is decided in Andorra, is the whole of the analysis.
Andorra’s own residence test
The Andorran personal income tax was introduced by Llei 5/2014 of 24 April. Article 8 of the consolidated Andorran income tax law treats a person as tax resident in Andorra where they remain more than 183 days of the calendar year in Andorran territory, with sporadic absences counted towards that total unless the taxpayer proves tax residence in another country, or where the main nucleus or base of their activities or economic interests is situated in Andorra.
The rate structure is straightforward. Article 43 of the same text sets the general rate at 10 per cent, applied to a base reduced by an exempt personal minimum of 24,000 euros under article 35, rising to 30,000 euros where the taxpayer is in a situation of incapacity. Article 37 gives the savings base its own exempt minimum of 3,000 euros. A credit under article 46 halves the tax on the general base above the personal minimum, capped at 800 euros.
Read on its own, that is an attractive and administratively light system. It is also half the picture, because nothing in it stops Spain reaching the same person.
The permit is not the residence
The immigration authorization most families take is residence without lucrative activity. Article 95 of the consolidated Andorran immigration law requires principal and effective residence in Andorra for at least 90 days per calendar year. Since Llei 2/2026 of 22 January the main holder must invest at least 1,000,000 euros permanently in Andorran assets, reduced to 400,000 euros if the investment goes through the housing fund, with six months to complete it. The qualifying assets run from Andorran real estate and holdings in Andorran resident companies to Andorran public debt, life insurance and non-remunerated deposits with the Andorran Financial Authority. The main holder also pays 50,000 euros to that authority, plus 12,000 euros for each dependent taking the same status, and those payments are now definitive rather than a refundable deposit. Under the regulation on residence without work, income has to be shown above 300 per cent of the annual minimum wage, with a further 100 per cent for each dependent.
Article 32 of the same law sets the duration, and the general rule is not the one to plan on here. It gives two years initially, then two, then three, and ten once the permit has been held for seven. But paragraphs 4 and 5 of that article put Spanish, French and Portuguese nationals on their own track: two years initially, three for every renewal, and ten after five years of holding it rather than seven.
The number that matters is 90. It is an immigration condition, well below the 183 days the Andorran tax law uses. A family that satisfies the permit precisely, spending three months a year in Andorra, has complied with immigration law and has answered nothing about where it is tax resident. The permit is treated as the conclusion of the analysis when it is the beginning of it.
The Spanish test runs in parallel
Article 9 of the Spanish personal income tax law sets out its own criteria, and they are not mirror images of the Andorran ones. A person is resident in Spain where they remain more than 183 days in Spanish territory during the calendar year, with sporadic absences counted unless tax residence in another country is proved, or where the main nucleus or base of their activities or economic interests is located in Spain, whether directly or indirectly.
The second limb has no day count in it. A person can be physically outside Spain for most of the year and still be caught, if the substance of their economic life remains Spanish. Where the operating company, the property, the bank relationships and the sources of income are all in Spain, the second limb does the work whatever the passport stamps show.
There is also a presumption. Spanish residence is presumed, subject to proof to the contrary, where the taxpayer’s non legally separated spouse and dependent minor children habitually reside in Spain. Families who move the taxpayer and leave the household in place are relying on rebutting a presumption, a materially worse position than not triggering one.
Where both tests are satisfied, the deadlock is not left open. Article 4.2 of the Spain Andorra double taxation convention resolves dual residence by permanent home, then centre of vital interests, then habitual abode, then nationality. It rewards the family that actually moved.
What Andorra is no longer
For years the Spanish analysis of a move to Andorra ran through the tax haven quarantine in article 8.2, under which Spanish nationals who move to a jurisdiction classified as a tax haven remain Spanish taxpayers for the year of the change and the four following tax periods.
That rule is still in force, but it does not apply to Andorra. The Spanish list of non-cooperative jurisdictions is set out in Orden HFP/115/2023, and in the consolidated text updated on 27 June 2026 Andorra does not appear on it. The quarantine is therefore not the obstacle it once was, and advisers still citing it work from a superseded position.
The consequence is easily misread. Removing the quarantine did not make Andorran residence easy to establish against Spain. It removed a mechanical bar and left the ordinary facts and circumstances test standing, which is harder to plan against because no calendar satisfies it.
The charge on the way out
Leaving Spain can trigger a tax event before the residence question is even reached. The exit charge in article 95 bis treats the unrealized gain on shareholdings as a taxable gain when a person ceases to be a Spanish taxpayer, provided they have been one for at least ten of the fifteen tax periods preceding the last one that must be declared, and provided either the aggregate market value of the shareholdings exceeds 4,000,000 euros, or the participation in an entity exceeds 25 per cent and the market value of that holding exceeds 1,000,000 euros.
This is the charge that ambushes founders. A family whose wealth is a stake in an unlisted operating company can find that moving crystallizes a gain on an asset that has produced no cash, in the last Spanish tax period, on a valuation set by the statute rather than by a transaction.
It is also why sequence matters more than destination. Whether the charge arises, and on what value, is decided by facts fixed before anyone applies for an Andorran permit.
Substance is the same word it is everywhere else
The evidence that supports Andorran residence against a Spanish enquiry is unglamorous and cumulative. Days present, recorded as they happen rather than reconstructed afterwards. A home in Andorra that is the family home rather than a second one. Schooling, medical care, vehicle registration and insurance that follow the family. Bank and professional relationships that migrate rather than duplicate. Directorships and management functions exercised where the person now lives.
Against that sits the evidence the other authority will assemble. Spanish property retained and used, a spouse and children who did not move, an operating business still directed from Spain, invoices and correspondence showing the same person acting from the same desk as before, and the digital trace that goes with it.
The exercise is not to win a debate about intention. It is to make sure the ordinary record of a life, assembled by someone unsympathetic, describes a family that lives in Andorra. Where it does not, the permit does not help.
The company follows the person
Families rarely move alone. A holding company, a consultancy or an intellectual property vehicle usually moves with them, or is incorporated in Andorra shortly after arrival, and the file treats it as a separate question. It is not. Under article 8.1 of Ley 27/2014, a company is Spanish resident where the direction and control of its activities as a whole sit in Spain, and article 4.3 of the convention gives a dual resident company to its place of effective management. Where the only person who manages it has an unresolved position, so does the company.
This is where a half-completed move becomes expensive. An Andorran company whose sole director spends most of the year in Spain, signs from Spain, negotiates from Spain and meets its counterparties in Spain is exposed to a Spanish claim that it is managed there, whatever its register of shareholders says. The claim does not depend on the individual being Spanish resident; a company can be found to be managed in a state where its director is not resident.
The second exposure runs the other way. Where the Andorran entity invoices a Spanish operating business that the same family controls, the pricing of those invoices falls under article 18 of Ley 27/2014, which requires related party transactions to be valued at market value on the functions actually performed. An Andorran company with no employees, no premises of its own and no decision-making beyond the founder’s laptop will not support a management fee sized to move profit across the border.
A structure should not claim to do in Andorra anything the family is not physically doing there.
How this file should be built
The order of operations is what clients resist and what decides the outcome. The Spanish exit position is analyzed first, on the shareholdings as they stand, because it determines whether the move has a cost before it has a benefit. The household position comes next, because a split household imports a presumption the rest of the file then has to fight.
Only then does the Andorran side become useful. The permit is chosen, the payments and the investment commitment are met, and the day count is planned against the Andorran tax test of more than 183 days rather than the immigration floor of 90. Where a family cannot commit to the higher number, the honest conclusion is that they are buying a residence permit and not a change of tax residence, and the file should say so in writing.
Proximity remains the attraction. It is also why a Spanish inspector will look, with the whole of a family’s Spanish life available. Andorra works for families who actually move. It does not work as a postal address two hours from the life they kept.
