Telling the impots you're leaving France in French Finance Posted February 15, 2010 It's actually not as complicated to sort out as you might think. When I decided to leave France 6 months ago, I just wrote to the impots at the e-mail address indicated on my most recent tax return (providing my unique tax number which is printed on the tax return), stated that I would be permanently moving to the UK on the 17th August 2009, and gave them my new address.I explained to them that I would still have French income to declare for the period Jan-Aug 2009, so please could they send me my next tax declaration to my new address in the UK. I also explained that after moving to the UK, I would no longer have any income from French sources. That bit is important, because it affects whether you need to keep filling in French tax returns or not.It all worked fine, they just wrote back saying thank you for letting them know, and that they'd entered my new address onto their database. I know they've definitely done this, because since being back in England I've received a water bill from them, sent directly to my new address (not in the redirected mail).Thinking about it, the people at the tax office must deal with this sort of thing all the time. There's a lot of Brits out there moving back to the UK from France, so they've seen it all before.
