Connecticut Extends Business Tax Filing Deadlines

Businesses in Connecticut will have an extra 30 days to file their taxes in order to deal with fallout from the novel coronavirus outbreak, the state’s Department of Revenue Services said Monday.

Gov. Ned Lamont (D) announced the closure of bars, restaurants, gyms, and entertainment venues, after canceling public school Sunday in concurrence with the tri-state area’s regional lockdown of large gatherings.

Meeting tax deadlines is much less of a priority for many businesses and individuals right now, according to Marc Finer, chair of the Tax Practice Group at Murtha Cullina, a Connecticut-based law firm.

As businesses across Connecticut shift to working remotely or closing down entirely, they are focusing on making sure their employees get paid, Finer said. “Personnel has become scattered, focused on other priorities.”

In conjunction with Lamont’s emergency declarations the agency announced:

  • Pass-through entity tax returns filing extended to April 15, with a June 15 payment deadline.
  • Both filing dates and deadlines for Unrelated Business Income Tax and Corporation Businesses postponed to June 15.
  • For individuals’ income tax filings, the department said, it will adjust due dates “to align with any specific, actionable announcement from the Internal Revenue Service.”
