QB Issue Resolution:
If the tax table was already updated for the current year, you can still view the 2017 data. However, the date will be in 2018, which is why QuickBooks no longer allows you to e-file forms for previous years. You can use this data as a reference in filling the DOR L-1 form through the state website.
For further assistance with filing the return, you can contact the Louisiana Department of Revenue.
