¿Qué documentos necesito para demostrar que fui residente solo una parte del año?

You must complete a final return for each Pennsylvania jurisdiction in which you lived. Provide Keystone with a copy of the final return for each jurisdiction, designate your part-year residence status on the local return where indicated and complete the ITR-1 Schedule with your return. If you moved to or from an area, where you are not required to file a final return, provide Keystone with documentation, such as a lease or utility bills, showing the other address and duration of residence.
