Get your taxes done using TurboTax

When do I become a resident of PA? Is is automatically applied once I move there and start working there? Or is there something more official I need to do i.e. file paperwork with some government agency?

 

How do I give up the homestead on my NY residence once I convert it to a renal property?

 

What if I decide to keep NYC as my primary resident, rent an apartment in Philadelphia while working in Philadelphia? Will I end up paying more in taxes?
