the plan sponsor went from a basic safe harbor match in 2018 to a safe harbor non-elective in 2019. unfortunately, the basic safe harbor match deposits were still being made during all of 2019. Can we do a self-correction? If so, I'd like to just reclassify the funds as SHNEC but some participants may have overages if they were deferring over 3% of pay. Can I just forfeit the overages? Do I have to calculate earnings on the overages to be forfeited?
