There are a lot of internet sites that help you figure out the best place to live.
I only saw one that listed the best places to RETIRE.
It is not a new study, but Kipliger's found that DELAWARE is the best state in the entire country. I am surprized that more people don't know this.
There are three counties, the bottom two are where the lowest taxes are.
Another thing people do not know is in New York State they have a program named STAR. I once saw ALL the benefits of this program, but they are hard to find. It was VERY favorable. I think you had to be living there for a while, but your property taxes were frozen and your retirement income was hardly taxed, etc. I am not sure, but I think there were great public transportation deals and all sorts of programs.
I was thinking of moving in the vicinity of Rochester once.
Whatever you decide, be sure to check out that some will tax investment income and tangible property. Some low tax states will have high county taxes (Florida?) depending on the county and town taxes, too.
If you have kids to inherit, inheritance tax law will apply for that state.
This is a really good site, specifically for retirees. I notice the STAR program is mentioned here. It is not double talk and you might do well to try to crunch the numbers and research this for yourself. People who I once worked with would tell me to look into it and I would laugh because NY taxes are supposed to be so high.

Don't let the generalities on the first page sidetrack you. Look up their individual states and see how your specific situation fares.
