Hello again jr,
If you are currently working in the state of NY, then it is correct that you should be paying NY taxes, even though you live in the state of PA. The way state taxes work is this:
You pay state taxes to:
1. The state where you are a resident and
2. Any state where you have earned income
When you work in a different state than where you live, the employer is required to withhold state taxes based on the state where you actually work. So if you are now working in NY, they would withhold NY taxes. At the end of the year you would then file a non residen tax return with the state of NY to report your income from that state.
You would then also file a return with PA since that is your resident state. You would report to PA your income from all states, but then PA would allow you a credit for the state tax already paid to NY.
Once you start working in PA, you will no longer be liable for paying any NY taxes. There should not be any new forms you need to fill out. It is the employer's responsibility to withhold the correct taxes based on the location you are working. So anyone who is working ouf of this location in PA should automatically be having PA tax withheld from their checks, and your NY withholding should stop.
