Moved from VA to FL July 8 2025 - What Documents Do I Need To Submit (If Any, other than W4 and New FL Lease) To Prove To VA Govt. That I Left VA Permanently For FL?

I have just moved from VA to Florida effective July 8 (date of new 1 year apartment lease signature in Florida). I am a remote worker (employer address has always been in PA for many years per my W2). I have also changed my address effective July 8 from VA to FL on my W4 with my employer and my 2025 W2 will have my FL address.

So I have spent 187 days this year in VA and will spend the rest of the year (and beyond) in Florida. Will I be paying VA income tax only for part of the year on form 760PY as Florida has no income tax? Do I need additional documents over and above my new lease and W2 to prove that I became a Florida resident from July 8 to Dec 31 2025 and beyond? Also, because I lived in VA for the first 187 days, will I have to pay VA state income tax for the whole of 2025 because I spent more than 183 days in VA? Do I need to get my Florida driver's license and change my vehicle registration to FL immediately to prove to the govt. of VA that I left VA? What documents, if any, could the Govt. of VA dept. of taxation possibly ask for as far as my VA income tax filing for 2025 is concerned?
