Form 4868 is a form that you can file if you owe money and cannot mail your documents by the deadline which is usually April 15th to request a 6 month extension on your tax filing.
Please note that the extension is filed only to extend your time to file. If you owe money to the tax office, you would have to pay the liability by the deadline. Also, you cannot file an extension after the deadline. An extension is not required by the IRS if you have a zero balance or are due a refund.
For the extension you are required to have a valid taxpayer ID (SSN or ITIN).
You can file the extension and get more information about it on the IRS website here.
Info: Please keep in mind that you cannot file an extension with Sprintax.
