Living between France and Italy...life, food, cars and tax!

Just as predicted, shortly after taking residence in Italy my partner's job involves us all moving to Paris next week. I've read several posts when people have stated they live between France and Italy and I'm curious to know what people's feelings are on the two countries side by side? So far I have to say Italy wins hands down on the food front which really surprised me! Should we have a car registered in France or Italy? We need to buy a left hand drive.

I'm also no entirely sure how to handle the 'residence' thing. We have a rented house in the UK which we haven't lived in for several years, we'll be renting in Paris and have what will be our long term home in Lazio which is partially restored but still has a long way to go which is currently our 'prima casa'. I am assuming we'll have to change the Italian house to 'seconda casa' until we return as there is no point putting ourselves through the IVIE and Italian double taxation on my UK income if we are not living there. My understanding is that you cannot have 'prima casa' status in Italy without being resident there and if you are an Italian resident on the anagrafe for more than six months you will be liable to Italian taxes, IVIE etc. Any thoughts?

I don't really have a clue for sure, but suspect it will depend on how long you are staying in each location i.e. France and Italy I'm guessing very little in the UK? Others here may have a better idea, but may also need more information to help. If there long enough could you lease a car there, checking if the lease allows you to take the car to Italy?

Rachel, I think as others have pointed out in this case you need the Professional help of a good Commercialista or Accountant, who will be able to advise you properly when in possession of all the facts and figures.
No matter how well meaning we are on this site, I would not take Fiscal advice on anything other than from a qualified professional.
