How do I know if it is filing my returns for 2017 and 2016?

[xmasbaby0 · Accepted solution]

You cannot combine income from 2016 and 2017 on the same tax return, nor can you use the current online software to file a 2016 return.  The online software can only be used for a 2017 tax return.  If you need to file for 2016 you have to purchase the 2016 software that you install to your computer.  A 2016 return can only be printed, signed,and mailed.  It cannot be e-filed.

Online preparation and e-filing for 2016 is permanently closed.

To file a return for a prior tax year

Only a 2017 return can be prepared online and e-filed. 

 If you need to prepare a return for 2014, 2015, or 2016 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

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

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.
