You can also select the xxx.tax2016 file and right-click (or Control+Click) on the file and "Open with" and select TT 2016 (which should be the default). TT 2016 should now launch and open the data file.
You are also "supposed" to be able to to "Always Open With" but that feature does not seem to stick when I try it.
1) From the OS X Finder, right-click (or Control+Click) on the file to change the default app for and hold down the OPTION key so that the “Open With” menu becomes “Always Open With”
2) Continue to hold OPTION and select the application you want to set as the default for this file
