And Abruzzo is one of the regions that caps the first 10 years of taxes @7%.
There's lots of other good general advice here about the residency process. I just want to clarify the statement you made above. The 7% tax regime (which I am currently enjoying) applies to 9 tax years, not 10. And only if you settle in a town in one of the 7 southern regions with a population under 20,000.
Not hard to do in Abruzzo, where there are only a double handful of towns bigger than that, but I just wanted to be sure you were clear that the tax break is restricted to new residents of small towns.
Side note: I passed the B1 test this year and didn't find it nearly as challenging as the driver's license exam. I didn't see it mentioned here, but you must obtain an Italian driver's license within one year of taking up residency, and that means taking the theory and practical tests in Italian only. Your U.S. license is invalid for driving in Italy after that time, and if you are stopped, they can impound your car and confiscate your U.S. license.
Edit: instead of buying and insuring a car, I recommend you look into a subscription car service such as Drivalia Car Cloud. They offer annual subscription contracts to rent a car, including all maintenance and insurance. You can cancel the subscription anytime with no penalties with one month notice. It's significantly cheaper than the French car leases and can be used for 1-12 months as needed. I'm on my third year of this subscription plan and it's been hassle-free and affordable.
