There has been some confusion about the tax filing / tax payment deadline extensions. On Friday, March 20 we got clarity that both the filing and the payment deadlines have been extended from
April 15 to July 15 giving all taxpayers and businesses additional time to file and make payments without interest or penalties.
If you are expecting a refund, however, the Treasury Department encourages you go ahead and file as soon as possible – the sooner you file, the sooner you will get your refund.
