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
| Form | Type | Filing frequency | Due date |
|---|---|---|---|
| Form PA-W3R | WH | Quarterly | Last 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
