Correct!! and that was my point to Lacerte the last few years -

This year with the SALT limit at $ 40 K it has become an issue

Lacerte advised us to enter on Itemized Deduction list as "Other Taxes" 

But careful as this amount is ADDED when the $ 40 K limit is determined - not good as now we will need to determine which client gets the benefit vs which one is over the $ 40 K SALT limit

A very simple solution would be to add this under the NJ FLI screen (same as they have NJ-NY SDI on one line)
