If you expect to get a refund, there is no penalty and you can file after the filing deadline tomorrow. with no worries. Or if you need an extension you can request an extension. An extension gives you more time to prepare the Form 1040 but not extra time to pay tax due---so if you expect to owe you should pay the estimated tax due with your extension.
