An SFO (single family office) is a structure that manages the assets of a single family. It is a non-commercial structure, created by families who are often very wealthy, to bring certain investment functions in-house. An SFO makes sense only for substantial wealth, often above 100 million euros, enough to fund a dedicated team (see below). Families with more modest wealth tend to turn instead to a multi family office (MFO), an independent commercial structure that by definition serves several families.
Because it is a non-commercial entity, an SFO pays no tax and is not subject to VAT; consequently, it does not recover VAT on its purchases. There is no procedure specific to SFOs, since they are not specifically regulated in the Principality of Monaco but are governed by the general law applicable to companies. The term “single family office” is simply descriptive. Subject to prior authorization granted by the Prince’s Government, the required legal form today is the Société Anonyme Monégasque (although rare exceptions may have existed in the past), which is subject to a minimum share capital of 150,000 euros. It is a more sought-after form, and a more robust one for significant investments. Its corporate purpose is not imposed by statute, but it is nonetheless standardized and reflects the obligation of exclusive management (the acquisition, subscription, administration, and management of all movable and immovable property, securities, or rights, as well as any business and asset structure concerning only the company or the founding family), together with a strict prohibition on managing or administering assets belonging to third parties (which could otherwise fall under the regime for MFOs or for regulated activities).
An SFO does not invoice clients, which is why it falls outside the scope of taxation. Its corporate purpose must therefore relate to the management of the family’s assets, to avoid any risk of requalification as a commercial, and therefore taxable, activity. It is worth recalling that in Monaco, the family for which the SFO operates, which must be resident, receives dividends and capital gains that are not subject to tax. There is no inheritance tax in the direct line, and it cannot exceed 16% between unrelated persons. French nationals residing in Monaco must continue to pay their income tax in France. For them, the advantage is therefore smaller, but it remains very attractive in certain successions, depending in particular on how long the deceased had been resident in Monaco at the time of death.
In every case, the regime is advantageous only if there is real substance: effective residence of the family, an administrative team on site, and activity consistent with the corporate purpose. It is important to check whether income of foreign origin may be taxed in the country of origin. Taxation depends heavily on nationality, on the country in which the assets originate, and on the applicable tax treaties.
For a wealthy family, an SFO above all meets a need for organization and control, with a view to rationalizing the management of its wealth. An SFO can bring together the real estate, administrative, and estate planning expertise of a single family. The arrangement spares the family from depending on several banks or advisers with no overall view, and allows management in line with the family’s expectations. Beyond a certain level of wealth, a dedicated team can cost less than the combined costs of several private banks, asset managers, and advisers (management fees, custody fees, commissions, professional fees), while generating savings on salaries and premises.
An SFO that centralizes all of a family’s assets can negotiate better terms with banks, asset managers, and funds, and put its service providers in competition. With a group-wide view, the family can access direct investments or private equity, and thereby limit duplication and concentration risk.
The SFO provides a framework for preparing succession, training the next generation, and organizing philanthropy, across several generations.
Above the legal structure, families often put in place informal or more formal bodies, such as a family council or a family charter setting out values, decision-making rules, and investment policy. An investment committee, which approves major decisions, is often paired with an advisory board of independent outside advisers. Sound succession planning and clear governance reduce the risk of conflict and loss of value at the time of transfer. That is an indirect economic gain, but a very real one.
Certain points call for particular attention. The structure must have real substance: premises, staff, and activity that is coherent and fully consistent with the corporate purpose (a requirement under Monegasque law). This is what protects against the risk of tax requalification mentioned above. Although SFOs are not subject to Law No. 1.362 of August 3, 2009, as amended, the cornerstone legislation in Monaco on combating money laundering, terrorist financing, the proliferation of weapons of mass destruction, and corruption, rigorous compliance arrangements should nonetheless be put in place, in particular by keeping the registers of beneficial owners and basic information up to date.
Beyond strictly economic considerations, the appeal of establishing in the Principality rests on major geographic advantages, the exceptional stability of its institutions, an optimal level of security for families and property, and an exceptional quality of life, with first-rate healthcare and a high-quality education system. The economic advantages of an SFO thus derive above all from rigorous management and cost control, within a unique institutional and security environment.
