Corporate Tax Deadline and Extension Information (March 2020)

A note from 2026

This post went up in mid-March 2020, days before the IRS began moving deadlines in response to COVID-19. We have preserved it at its original address as a record of guiding clients through that period. Specific dates below are historical; the extension principles are not.

What we told clients then

File the extension even amid chaos — an extension of time to file is not an extension of time to pay, so estimate and pay what you can to limit penalties and interest. Keep documentation of everything, because relief provisions were changing weekly. And do not let deadline confusion become non-filing; the businesses that stayed current through the disruption avoided years of cleanup afterward.

What still applies

Every word of the extension logic. Extensions buy filing time, never payment time; estimated payments still anchor your penalty exposure; and in any disrupted year — pandemic, disaster, or personal — filing something on time beats filing nothing perfectly.
