A new Protocol (signed 10 October 2019) to amend the method of avoiding double taxation between France and Luxembourg appears to apply the tax credit method to avoid double taxation. According to the text of the new Protocol, the method used to prevent double taxation of French tax residents working in Luxembourg is a “tax credit equal to French tax.” Based on this language, Luxembourg taxable income earned by a French tax resident would be taken into consideration to determine French tax liability.
To eliminate double taxation, the Protocol adopts two methods:
The effect of the “tax credit equal to French tax” method would be similar to the impact of the exemption with progression method.
To benefit from a French tax credit, the salaried income must actually be subject to Luxembourg tax. This treatment re-opens the discussion in Luxembourg about what supporting evidence would the French tax authorities accept.
