Mokryna All I know (or think I know) is that CGT is charged on all house sales in France, regardless of whether it is your main residence or a second home, but the amount pays goes down gradually until, at 30 years, no CGT is due at all. As we have had our holiday home for 32, nearly 33 years, we have no tax to pay.
However when we will have to pay CGT on the amount when we bring it back to Britain. However, there are a whole lot of things we can add to the original price to reduce the amount of taxable gain. We have made immense changes to the house, it was bought as a project and we have doubled the amount of useable space, added bathrooms rewired etc, but, unfortuantel DH did most of it, so the only costs were materials and we can only claim for those works, such as window replacement and some plumbing, which was done by tradesmen.
