In order to prepare a return for 2015, 2016 or 2017 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

  (if you want to prepare on paper for free:  )

You can download the Forms and Instructions from the IRS web site:

Remember to prepare your state return as well—if you live in a state that has a state income tax.
