What percentage of taxes do you have to pay on one thousand dollars in PA?

It depends :)

Pennsylvania state income tax is a flat 3.07% with no deductions. So on $1,000, you would owe $30.70 to the state.

However, throughout Pennsylvania, you also pay local income tax, and that varies by township or borough or municipality--whatever tax area you live in. The only way to find out that number is to call you township or borough or municipality offices and ask (or, sometimes it's listed on their website--if your area is large enough to have a real website :) So figure an additional 2-3% for local income taxes.
