A big advantage for you is moving from NY to PA that you will pay MUCH LESS tax than you do now - provided that you don't live or work in Philly proper.
In NY your State income tax is:
income between $20,001 and $100,000, your tax rate is 6.85%.
income between $100,001 and $500,000, your tax rate is 7.375%.
In PA your state income tax is 3.03%. NICE, right?!!! But if you live or work in Philly you'll also pay 4% city tax.
So - please do consider living in nearby Bucks County (just north of Philly). They have some of the best school systems in the entire state. And are still close to whatever you like with major highways nearby. Note - a few towns in Bucks do have a 1% earned income tax (wage tax) - but you can easily avoid these towns. Several towns that I would recommend for your consideration are the following: Trevose, Langhorne, Yardley, Bristol Borough (not Bristol township though). None of these have the 1% wage tax.
Moreover your PROPERTY Tax will be MUCH lower in PA. Your money will go a long way out here. That's why I'm moving from NJ to PA - quite literally just across the river (well - and 12 miles south).
