Get your taxes done using TurboTax

You don’t need to file Form 4868 or use TurboTax if you make a payment using the IRS
electronic payment options. 
You can pay all or part of your estimated income tax due and **indicate that the payment is for an extension** using Direct Pay, the Electronic Federal Tax Payment System, or using a credit or debit card. Your extension is then automatically granted and you will receive a confirmation number for your records.

Any amount, even $10., will do.
