PSD Codes and Residency Certification Form
Pennsylvania earned income tax is flat across the state and does not require any witholding forms, but via Act 32 local municipalities collect their earned income taxes through the state and that does require a state form, the Residency Certification Form. A copy of that form is available on the state web site, and a list of the associated Political Subdivision Codes (PSD Codes) needed to complete the form is there too. The state also provides an online look-up tool for the PSD Codes. The Pennsylvania links are prone to suddenly changing, if you do not see what you are supposed to at those links please inform the Webmaster.
