I have an employer with a SH plan, 3% NEC. They also provide a match of 100% of 6% and an integrated profit sharing contribution. So, very generous to employees. Very nice employer - pays employees well, etc. Small company with less than 10 employees. The owner's wives signed forms saying that they wanted to withhold 6% of pay (since that is amount necessary for full match) but they actually contributed up to dollar limit, which for them was about 75% of pay. They are being audited and auditor wants wives to return all deferrals over 6% since that is what the form says. This seems ridiculous to me since plan is safe harbor, no one was harmed etc. Any suggestions on convincing auditor to let deferrals stay in plan?
