Andorra and San Marino have signed landmark association agreements with the European Union that could eventually give their citizens broad rights to live, work and study across the EU. For non-EU investors, however, the distinction is crucial: acquiring residence in either microstate will not itself create EU free-movement rights.
The Two Microstates Signed Their EU Agreement on 19 October
The European Commission signed the Association Agreement with Andorra and San Marino on 19 October 2026, establishing a framework for both countries to participate much more deeply in the EU internal market. The agreement covers trade, investment, economic cooperation and a wide range of regulatory areas, while financial-services integration will proceed gradually and remain subject to supervisory assessments.
Commission officials described the level of market access as comparable in important respects with that available to Norway, Iceland and Liechtenstein through the European Economic Area. Once implemented, the arrangement is also intended to expand opportunities for citizens of Andorra and San Marino to live, work, study, retire and establish businesses across Europe.
Yet neither country is joining the European Union, and neither is becoming a Schengen member through this agreement. That distinction becomes particularly important for investors evaluating residence purely for mobility purposes.

Investor Residence and Citizenship Are Now Very Different Assets
For an Andorran or Sammarinese citizen, the eventual free-movement component could be extremely valuable. A national passport from one of the two microstates would become connected to far broader opportunities across the EU internal market once the relevant provisions take effect.
A foreign investor holding only Andorran or San Marino residence does not automatically inherit those rights. Immigration policy for third-country nationals remains primarily national, and specialist analysis of the agreement confirms that non-EU investor-residence programmes remain separate from the citizenship rights created by the association arrangement.
That difference highlights one of the most important principles in mobility planning. Residence, permanent residence and citizenship are not interchangeable products. The value of a residence programme can change substantially when the passport available at the end of the naturalisation path becomes more useful — but the investor has to reach citizenship first.

Andorra’s Residence Proposition Remains Selective
Andorra continues to operate residence routes for financially independent and internationally mobile individuals, but the country’s policy has become more restrictive as the government attempts to manage population growth and pressure on housing. For passive residence, current rules require a substantial investment in Andorran assets together with a non-refundable state contribution. The government announced earlier in 2026 that new passive residents would generally face a €1 million minimum investment plus a €50,000 non-refundable contribution for the principal applicant and additional amounts for dependants.
Andorra has simultaneously tightened property-related measures. Its foreign real-estate investment tax was increased in February, with the rate on a first qualifying foreign property acquisition rising from 3% to 6% and the rate for a second home rising from 5% to 10%.
These policies show that closer EU integration does not mean Andorra is opening unlimited access to foreign residents. The principality continues to balance international capital with a deliberate strategy of controlled population growth.

EU Nationals Will Gain Rights — but Andorra Can Still Use Quotas
The association agreement also incorporates safeguards reflecting the exceptionally small populations of both countries. Specialist analysis indicates that Andorra will be able to operate annual quotas for economically active residents, passive residents and seasonal workers even as EU free-movement rights become incorporated into its relationship with the bloc.
That compromise matters. Full, unrestricted free movement into a microstate with a population measured in tens of thousands could create profound housing and infrastructure pressures. The EU has therefore accepted arrangements designed around the countries’ exceptional demographic characteristics rather than applying an entirely unlimited model.
For EU nationals considering Andorra, the proposition could therefore become easier in legal terms but still constrained by availability. For non-EU investors, the current national residence route remains the relevant pathway.
Tax Remains Outside the Core Agreement
Another major point for HNWIs is taxation. The agreement integrates Andorra and San Marino more deeply with the European economy, but it does not turn their domestic tax systems into ordinary EU tax regimes. Andorra’s declaration accompanying the agreement explicitly states that taxation falls outside its scope, although the countries continue to participate in international standards on transparency and information exchange.
That means Andorra can retain the characteristics that made it attractive to some globally mobile entrepreneurs in the first place, including a comparatively low personal and corporate tax environment, while gaining closer economic integration with the EU. San Marino similarly retains domestic control over its residence-linked tax incentives.
For wealthy families, that combination may increase strategic interest in both jurisdictions, but residence should never be confused with a shortcut to EU citizenship or unrestricted EU mobility.
The Agreement Is Signed but Not Yet Fully in Force
Investors should also avoid treating the new rights as operational today. The agreement still requires the consent of the European Parliament and additional ratification procedures before conclusion and provisional application can move ahead. Andorra also intends to put the agreement through its own domestic democratic process.
Until that process is completed, existing residence and immigration rules continue to apply. The signature is a major geopolitical milestone, but it is the start of implementation rather than the end.
