I moved to PA when I retired 20 years ago to avoid the high income tax in Maryland. It is an improvement but not nearly as good as Florida.Josh, one option is to look next door to Pennsy. There is only income tax on earned income, i.e. 1040 stuff.
I have an unqualified retirement plan which PA didn't tax until about three years ago. Now it's considered earned income. FL has no income tax at all. When Florida needs money they get it from the tourists. And yet they keep coming back.
The property taxes in PA are high - $4,500/yr on a house assessed at $350K. My PA "Homestead Exemption" saved me a whopping $10/yr. The property taxes on my Florida house are a little lower - $3,600 on a $350K house but in central Florida that amount of money buys twice the house. My Homestead Exemption in FL is $1,100/year so my net property tax in Florida is half of what I pay in PA.
PA also has a "Death Tax" which Florida doesn't. If your net worth is $100 when you die PA wants $4.50. If you own property in PA when you die the state wants 4.5% of the value even if you're not a PA resident. My wife and I will save our kids quite a lot of money by going through all the necessary steps to becoming Florida residents. It's way more than just buying a house and calling it home for 6 months believe me. It's worth it but still a real pain in the butt. Florida welcomes you with open arms but PA really doesn't want to let you go.
