I live in Palmer township, home is valued by the township as $289k and we pay a total of $6800 per year. There are three annual bills which make up the typical one bill you would get say in NJ, one from the school, one from the county and one from the township. Most people mistakenly compare the school bill with other States like again NJ and they say that PA taxes are much lower, but that's not true. We owned a home in NJ valued higher and paid less taxes.
The other thing to consider is that in Palmer township income from all sources are taxed at 1% of gross income, no deductions allowed.
Hope this helps.
