In a recently published judgment, the Administrative Tribunal of Paris has judged that a resident of Switzerland should pay the same income tax rate on capital gains upon the sale of French real estate as a French resident, because of the specific wording of the France Switzerland tax treaty.
Up till now Swiss tax residents, that own the property directly or through a transparent S.C.I. are treated as non-EU residents and pay 33,33% withholding tax on capital gains whereas French tax residents only pay 16%.
Even though the Supreme Court has not yet confirmed this judgment it is possible and advisable to already introduce a claim in order to get back the difference from the French tax authorities, (i.e. 17,33% of the taxable gain).
In case they refuse the case can be brought before the Courts.
Please note however that in France, in principle, only a limited period is available to introduce such a claim. Claims in respect of the tax year 2008 must be claimed at the latest December 31st, 2010.
