I have received a proposal from a company, FRTS, at the instigation of the notaire , to act as a fiscal representative in relation to capital gains tax on the sale of our french house owned with our relatives through an SCI. (Minimum fee 2000 euros!?) Are these a reliable company? Are there any other options? I thought this practice of requiring insurance against payment of tax by non residents had been eliminated under EU competition rules - is it still current?
