"Alexis, I'm moving to Barcelona for my retirement, but I'm lost between Spanish wealth tax, the taxation of my rental income in France and this famous 'Beckham Law'. How should I structure my assets to avoid double taxation while making the most of the dynamism of Iberian property?"
Spain is not merely a dream destination for its quality of life; it is a land of major wealth opportunities in 2026. However, its decentralised tax architecture and specific reporting obligations (such as the famous Modelo 720) make it a complex terrain for the uninitiated. Settling or investing in Spain without a robust international wealth strategy means exposing yourself to costly tax friction.
At Balmont Conseil, we act as the architect of your wealth strategy between France and Spain. As a Wealth Engineer supported by an artificial intelligence dedicated to wealth management (ALTA), my mission is to combine top-tier human expertise with cutting-edge artificial intelligence to navigate the legal specificities of Spain. We turn regulatory complexity into a competitive advantage for your wealth.
Why is wealth management in Spain unique?
Spain is not a uniform tax bloc. It is a country of "Comunidades Autónomas" (Autonomous Communities) that hold significant regulatory power over key taxes: wealth tax (Patrimonio), inheritance tax (Sucesiones) and IRPF (income tax).

Our services: bespoke support for expatriates
At Balmont Conseil, we do more than simply manage investments. We build a structured wealth audit to secure every aspect of your life in Spain.
Tax strategy and the Beckham Law
For talent coming to work in Spain, the special tax regime (better known as the Beckham Law) allows you to be taxed as a non-resident for 6 years, with a flat rate on Spanish income and a near-total exemption on worldwide income.
We assess your eligibility in order to maximise this tax optimisation in Spain.
Property investment in Spain
Spain remains a particularly attractive property market for French buyers. Whether you are targeting rental yield in Valencia or a second home in Marbella, we support you every step of the way:
- Investment process: From the legal checks on the property (Nota Simple) to obtaining your NIE.
- Property taxation: Optimising ownership structure (personal name vs civil-law company) to limit non-resident income tax (IRNR).
Financial investments and Private Equity in Spain
We select financial instruments suited to non-residents and Private Equity solutions in Spain to diversify your portfolio.
The aim is to seek returns uncorrelated with volatile markets, while respecting the tax treaties between France and Spain.
Cross-border expertise: the France–Spain bridge
The greatest risk for an expatriate is to overlook the interplay between the two countries. International taxation in Spain rests on a bilateral treaty that we know inside out.

Our methodological approach: security and performance
Balmont Conseil stands out through a human-scale structure combined with institutional computing power.
Balmont Conseil, a trusted partner for your Iberian future
Wealth management in Spain cannot be improvised; it is sculpted with precision. Between the complexity of Spanish civil law and the specificities of international tax treaties, every decision calls for bicultural expertise. It is a discipline that demands rigour, a keen understanding of local particularities (such as the fiscal autonomy of Madrid or Andalusia) and a comprehensive view of your interests.

Expertise that Tames Spanish Complexity
By choosing Balmont Conseil, you benefit from personalised support that turns local constraints into opportunities:
-
Mastery of Wealth Tax (Patrimonio): We devise capping and optimisation strategies so that your success is not penalised by a tax on your accumulated assets.
-
Securing the Transfer of Wealth: We anticipate inheritance tax (Sucesiones), which varies enormously from one region to another, to protect your loved ones without major tax friction.
-
Engineering for Inbound Residents (Beckham Law): We audit your eligibility for preferential regimes to maximise your purchasing power from the moment you settle in.
