Using forfeitures to help fund safe harbor contribution

It is my understanding that at one time - forfeitures were not allowed to be used to fund safe harbor contributions.  I can't find when/if that changed and is it ok to use forfs now to reduce the safe harbor contribution to employees.

Regs were finalized in July of 2018 (I think that's when it was) allowing for that change. The original position always seemed strange to me, the change was a welcome one.

You may have to do a plan amendment... Check into it.

Are you certain that you don't already have such an amendment? A lot of document sponsors/providers/practitioners adopted this amendment on behalf of their clients.
