As you have sevral different kind of assets take very good financial advice as the french tax man has very sticky fingers. I wish I did.
1) investments: you will pay on dividends intrest and so on your marginal rate and on top of that social security tax CSG which is about 17%
They claim that they deduct foreign tax already paid but that’s only partially so. Your investment might be tax exempt in UK law but the french tax man will take its part.
Partial reduction apply but often not or at a lesser rate on foreign assets
2) rental income taxed income tax and CSG again. reduction apply for furnished and so. Check what applies to foreign properties(my second one is in france as well)
3) Capital gains tax on investments and real estate. No clue what uk does but I moved to france from an exempt country. But if i sell investments they want to tax from day one so had it for ten years abroad would have paid naught.Move to france value 3(bought at one) sell at 4 french taxman will want to tax you on 3. And they are very good at finding out whatever accounts and assets you have.
4) Real estate same taxed if its not your main residence. You might be slapped with a hefty bill if you sell uk property check how much and how much time you have to sell when you move here. Exemptions apply in france dependind on period owned. Not sure for foreign property’s I never owned one outside France.
Its better and easier to move to france when you’re just poor and only have cash in your accounts.
Haute Savoie, Beautifull but most parts are very expensive prices driven up by those working in Switserland or those who used to work there and retired over the border. Check rental prices.
Annecy lovely on a postcard but traffic nightmare.
Learn to be very patient, learn french, learn french.
Oh yes lern French
Will you work under French management? They are a special breed, very top down, strick and believing they have the almighty knowledge. They are decades behind in management techniques(I live rurally which adds another decade at least).
Weather and riding is lovely though 😉
Country side is beautifull though.
