After you file

Thus...if you haven't done so already, download every year's PDF file for what years are available right NOW.

AND back those up on a flash drive too, and store in a safe place.

Then you won't be left in the dark struggling to find those older years.

Do this PDF save every year for the newest tax file you create.
