The program doesn't automate the limitation of post-2017 net operating losses to 80% of taxable income. 

Please have the program do this calculation as it is something the program should handle (and other tax programs do calculate it.) There have been multiple comments on the Lacerte forum about this issue.  

Lacerte's failure to implement this calculation is inexcusable. This is NOT new tax law.  It has been around for years.

This kind of complex calculation, that Lacerte has 100% of the data within the program to implement, is exactly what Lacerte SHOULD have implemented long-ago.
