5Verify and Correct Political Subdivision Codes for New Employees
You need to confirm that new employees have the correct political subdivision (PSD) codes and school district on the PA PSD component of their Tax Withholding card.
These values are derived during the hiring process; however, you should review them to confirm accuracy, particularly in jurisdictions where multiple PSD codes may apply.
Refer to the Pennsylvania Municipal Statistics (DCED) resources for latest PSD codes by address.
