1 Each French taxpayer must file an income tax return, even when his or her income is too low to be taxable. If this is the case, there are also ways to obtain relief from local property taxes.

2 If you do not know if you are a French tax resident or if you do not wish to become one, the best option is to keep a property in another country and live there at least 183days/year.

3 Pay less tax as a retiree. If you are a UK national who receives a private pension but is willing to become a French resident, applying to HM Revenue & Customs can offer tax cuts in your home country. The first application form informs UK tax authorities that you are moving abroad, and as such, reclaim any overpaid tax once you have settled in France. A second application form allows the French tax authority to inform UK tax authorities that you are a French tax resident.

4 Bank secrecy is forbidden and punishable in France. If you have foreign bank accounts, depending on the country, interest may be automatically reported to the French tax authorities. In France, income tax is collected by arrears so please make sure to have some money saved in view of next year's tax payment.
