Tax Year 2016: Will refund filing continue to May or did it end already?

When is the last day to file?

For this year (2016 tax returns) you have until April 18th to file.  If you can't finish by then, you can file for an extension Form 4868 of time to file (not to pay, if you owe).  The ability to file an extension will be available later this month within the software.
