We cannot advise you about that as we know nothing about your tax situation. You can still file your 2016 tax return after the filing deadline. You will be able to e-file up to October 16, 2017 at 11:59 p.m. If you are getting a refund, it will be OK to file past the deadline; you will not be penalized. However, if you owe tax due, your return will be considered late, and penatlies/interest will start to accrue.
After October 16, you will not be able to e-file. Your return will have to printed signed and mailed.
