Change to State Corporate Tax Deadline Signed Into Law

Legislation unanimously passed by the General Assembly to change the due date for the filing of Commonwealth corporate taxes has been signed into law by Gov. Tom Wolf.

Act 10 of 2021 changes the due date of Pennsylvania corporate tax returns from 30 days after the due date of the federal return to the 15th day of the month following the due date of the federal return.   According to a press release by the bill’s sponsor Rep. Keith Greiner, R-Lancaster, the measure also authorizes the Department of Community and Economic Development, in coordination with local governments, to extend the filing and payment deadlines for annual local income taxes to coincide with the deadline for federal and state returns.

The PA Chamber supported this legislation because it will bring greater predictability and stability to the Commonwealth’s business community.  The filing deadline change will help address confusion regarding the state tax due date for Pennsylvania’s corporate taxpayers.
