Overview

Pennsylvania employers who withhold state income tax from employee wages must file a quarterly reconciliation with the Pennsylvania Department of Revenue.

The TaxBandits API supports the automation of Form PA-W3R, Pennsylvania's quarterly withholding reconciliation return.

Forms supported​

FormTypeFiling frequencyDue date
Form PA-W3RWHQuarterlyLast day of the month following the quarter end

Key compliance notes​

  • Zero filing required. Form PA-W3R must be filed every quarter, even if no wages were paid or no tax was withheld.
  • Filed regardless of payment method. Even if tax was remitted by EFT, the PA-W3R reconciliation return must still be filed separately.

Before filing, you can simulate the entire verification flow in our Sandbox environment without submitting real data to state agencies. See how
