tax in different states

i moved to philadelphia from new york in june 2011 i work in new york and also own a small business in new york, which state do i file the tax in or what kind of tax will i need to file, thanks

Since you have established a residency in Pennsylvania you will be required to file an income tax return for that state. And since you were a part-year resident of New York, plus work and own a business located in New York, you will need to file there as well.

but to my understanding, i will need to file two separate federal taxes one for each state, and two separate state taxes as well one for each state, if im right do i still use my philadlephia address on the new york tax

No, you will only file one federal tax return. But you will file two state tax returns, and perhaps local city returns as well depending on exactly where you live and do business. And you would use your mailing address on all of the returns.

I strongly suggest that you have a tax professional prepare your returns for you, as multiple state/local returns with a business to report as well is something that is almost always beyond the grasp of a lay person.

thank you so much and i assume i can used some one in either state correct

Yes, any qualified tax professional in your area should have experience doing nearby state tax returns.
