Hi I am in a similar situation having sold a property in 2013, I have been looking on the internet and forums for help and have found a template of a letter to send to the Centre des Impots for non residents. You also need to include a copy of the bill that shows how much you paid in tax. hope this helps www.rivierareporter.com/doing-it-in-france/846-victory-for-second-home-owners Linda
