Sure...the Online software is active and available to an e-file a 2017 tax return until the middle of October....and shuts down permanently for 2017 after that.
After mid October you can still paper file 2017 taxes, but you have to buy, download, install, and to use the desktop software to do it after that...no e-filing after mid-October.....just paper-filing thru the Post Office
