You can file an extension today and then file your return anytime between tomorrow and October 15th.  There is not a minimum time you have to wait to file. 

There is no fee to file an extension, however, if you are expecting to owe money you would still need to make a payment with your extension.

How do I know how much I owe or don't if I haven't finished these new deductions
