States are still working out their own changes
Some states had already moved filing deadlines and, with Mnuchin’s (US Secretary of the Treasury) latest move, it’s possible that others will follow accordingly. Staying on top of that is a lot like herding cats, but ConsumerAffairs search for a good guide on the situation turned up the state-by-state filing guidance from the American Institute of CPAs. That guide also has links to each individual state’s updates as they become available.
