Partners getting W-2s, shareholders getting 1099s from their own corps, S-corps using K-1 income as plan comp, sole props deducting plan contributions in excess of SE income, SEP contributions for owners only, not covering employees, partner PC in an ASG sponsoring a plan just for the PC. All this stuff goes on all the time, apparently with little to no enforcement. Bringing it up is usually met with the reply “I’ve been doing this for years with all my clients, we’ve been thru audits, no problem”. Whatever.
