Abuse of Rights: Drawing the Line Between Tax Planning and Tax Reclassification

Recent decisions by the Committee on Tax Abuse (CADF) and several courts serve as a reminder that traditional wealth-planning structures—such as family loans, civil solidarity pacts, intrafamily transfers, or real estate OBO transactions—may be reclassified if their economic or family substance cannot be demonstrated. However, these same decisions also show that courts validate arrangements whose financial purpose is genuine and well-documented.

Family Loans, PACS, and OBOs: Three Textbook Cases
1. The Family Loan
Cash advances between family members remain a tool for financial solidarity, provided they are formalized. In a recent case, bank transfers made by a mother to her daughter’s company were reclassified as a disguised gift due to the absence of a contract, a repayment schedule, and interest.
 

This case serves as a reminder that any loan between family members must be documented in a written and registered agreement that specifies the repayment terms and, ideally, an interest rate—even a modest one. Otherwise, the tax authorities will presume that the transaction was a gift, resulting in gift tax liability and an 80% surcharge for abuse of rights.
 

2. The Last-Minute PACS
The civil solidarity pact (PACS), often used to protect the surviving partner, was upheld in a case where it had been entered into shortly before a death.
The tax authorities viewed this as a ploy to take advantage of the total exemption from inheritance tax granted to PACS partners. The Committee on Tax Abuse (CADF) ruled that the tax authorities had not provided evidence of a fictitious union: the PACS, even though entered into late, therefore produced its civil and tax effects.
 

3. Real Estate OBO
The real estate Owner Buy-Out (OBO)—the sale of a property to a real estate investment company (SCI) controlled by the seller and financed through borrowing—is often criticized for its impact on the real estate wealth tax (IFI).
The Compiègne Court of General Jurisdiction, however, approved an arrangement of this type, finding that the transaction pursued a clear patrimonial and family objective: reorganization of ownership, early transfer of assets, and the inclusion of the children.
 

The mere fact that the transaction reduces the IFI tax base is therefore not sufficient to constitute an abuse of rights, provided that the economic purpose is genuine.

The guiding principles: substance, proportionality, and traceability
These court decisions confirm that the distinction between tax optimization and abuse rests on three pillars:
• Economic or family substance: the existence of a genuine intent (to repay, to live together, to transfer assets, etc.).
• Proportionality: the tax benefit must not be the sole or primary purpose of the transaction.
• Traceability: every financial decision must be documented (contracts, bank statements, certificates, articles of incorporation).
 

Wealth management advisors must exercise caution. A tax-advantaged structure remains lawful if it is supported by demonstrable economic rationale. The tax authorities are now focusing their audits on transactions lacking real substance, where tax considerations take precedence over sound wealth management principles.
 

Abuse of rights does not penalize tax optimization in and of itself, but rather legal fictions that lack justification. In an increasingly technical tax environment, caution and documentation remain the best defenses.
