An extension of time to file will automatically process when you pay all or part of your taxes electronically by April 18. There’s no need to file a paper or electronic Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return.
However, an extension of time to file is not an extension to pay. You can file up to six months later when you have an extension, but your taxes are still due by your original due date. You can get an automatic extension when you make a payment with Direct Pay, the Electronic Federal Tax Payment System or by debit or credit card.
When paying electronically, you must select Form 4868 as the payment type and the payment date in order to get the automatic extension. Keep the confirmation you receive as proof of your payment.
