You are thinking of selling a property in France to one of your children, or giving it to them at a moderate value to organise your estate. How far can you go before the French tax authority recharacterises the transaction? A ruling of the Basse-Terre Court of Appeal (Guadeloupe) of 20 January 2020 (case no. RG 18/014111) illustrates the mechanism of the tax reassessment notice (proposition de rectification) and shows what a documented valuation could have avoided.
The case
In 2013, parents sold their son, by notarial deed, a plot of 8,466 m² for €21,952.66. In 2015, the regional public finance directorate of Guadeloupe took the view that the market value of the land was in fact €592,760. It recharacterised the sale as a disguised gift and claimed the corresponding duties, together with late-payment interest and penalties.
Before the Court of Appeal, the parents argued that the value of the land did not exceed €147,442, given the servicing works still to be carried out. They were unable to explain, however, why they had declared the same plot at €338,720 in their 2013 wealth tax (ISF) return.
The court upheld the reassessment.
The legal framework
Registration duties are assessed on the actual market value of the assets transferred (French General Tax Code, article 666). Where the price or the declared value appears lower than that market value, the tax authority may correct it (Tax Procedures Code, article L. 17), under the adversarial reassessment procedure (article L. 55). It then sends a reasoned reassessment notice, to which the taxpayer may reply.
A sale concluded at a price far below the value of the property may be analysed as a gift, that is, an act by which the donor irrevocably divests themselves of the thing given in favour of the donee who accepts it (Civil Code, article 894), concealed behind the appearance of a contract for value. Gift duties then become payable, with late-payment interest and, depending on seriousness, the surcharges of article 1729 of the General Tax Code: 40 % for deliberate breach, 80 % for abuse of law or fraudulent manoeuvres.
How the tax authority established the value
The authority proceeded by comparison, which is the reference approach for determining market value (Charte de l’expertise en évaluation immobilière, the French property valuation charter, 6th edition, November 2025, Title III, chapter 2, § 2.1). It retained six sales of building plots between January 2009 and 30 November 2012, whose average price came to €79 per m², and limited its reference to €70 per m². It added two transfers of 12 December 2012 and 8 August 2013, at an average price of €82.41 per m².
The plot was described as flat and buildable, bordering a road to the north and therefore easy to access, adjoining villas in part in an area of scattered housing, three kilometres from the sea, in a sector that is one of the department’s tourist hubs.
Against this, the sellers relied on servicing works, with no costing produced, and on a value three times lower than the one they had themselves declared for wealth tax. The court found that they had not shown the authority’s valuation to be excessive.
A moderate value in a gift or a partition: why not
Organising the fate of your assets during your lifetime is good practice. Assets left in joint ownership (indivision) to children who do not get on become hard to manage and to sell, sometimes to the point of a court-ordered partition. Where one child is interested in a property and the other is not, the second often prefers to receive cash now rather than in ten or twenty years. A property that is little used and poorly maintained deteriorates and loses value.
For these reasons, a gift made at a value slightly below market price, for example €80,000 for a property that would sell for €90,000 to €100,000, with the agreement of the whole family, does not seem abnormal to me. The market itself admits ranges, and a value in the lower part of the range remains defensible if it is justified.
Here, the gap was not of that order: a property declared at €338,720 for wealth tax was sold for €21,952.66, about 6 % of that value. It is that gap, not the principle of a transfer between parents and child, that triggered the reassessment. The same transaction, carried out by a sale or a gift on a basis close to market value, would in all likelihood have raised no difficulty.
What a prior valuation brings
Before setting a price or a gift value, it is useful to have a document that justifies the value adopted. Several sources exist: the notaire (French civil-law notary) and their office, who record comparable sales and have access to the notarial databases; a negotiator or valuer within the notarial network; a property valuation expert, whether or not registered on a Court of Appeal list.
The Charte distinguishes the opinion of value, which states a value without demonstration, from the valuation report, which justifies and demonstrates the value according to a methodology and engages the professional liability of the valuer (Title I, § 1.1). In the event of a reassessment notice, it is this second type of document that allows a useful reply to the tax authority: sale references, explained adjustments, a costed account of servicing works, access or buildability, checked where appropriate by a planning certificate (certificat d’urbanisme).
A valuation does not guarantee that there will be no audit. It guarantees that the declared value rests on a method, which changes the nature of the discussion with the authority: the debate is about comparables and adjustments, not about a figure put forward without justification. A valuer or your notaire can assist you in those exchanges.
