Prior year returns must be paper filed.
The IRS only accepts current year returns through October 15 of each filing year for e-file.
We now offer prior year return preparation for your convenience. From our homepage, click on "start now" to create an OLT ONE account (or sign in if you have an OLT ONE account). Prior years available are 2018, 2017, and 2016. Select to start a return for that year.
You must print, sign, and mail the return to the appropriate address.
E-file is not available for prior year tax returns.
