One of the biggest misconceptions in retirement plan administration is believing that a small mistake will stay small.
It rarely does.
A payroll employee accidentally misses one participant’s salary deferral. Someone figures they’ll catch it next pay period.
Six months later, the mistake has affected dozens of payrolls, employer matching contributions, earnings calculations, and participant notices. What could have been fixed in a few minutes has become an EPCRS correction project.
I’ve seen eligibility dates entered incorrectly. Loan repayments coded to the wrong participant. Automatic enrollment accidentally turned off after a payroll conversion. None of those errors looked significant on day one.
They became significant because nobody noticed them.
That’s one reason I encourage plan sponsors to perform periodic operational reviews instead of assuming everything is working correctly.
Retirement plans are built on thousands of transactions each year. Even if your providers do an outstanding job, mistakes happen. The question isn’t whether an error is possible. The question is how quickly it’s discovered.
Time is rarely your friend when it comes to operational failures.
The longer an error continues, the more participants it affects, the more calculations become necessary, and the more expensive the correction becomes.
I’ve learned that successful plan sponsors don’t ignore small issues because they’re small.
They investigate them precisely because they understand what experience has taught them.
Small mistakes have a way of growing.
The good news is that the opposite is also true.
Small habits—reviewing payroll reports, asking questions, documenting decisions, and conducting periodic compliance reviews—also grow over time. They become a culture of compliance that protects both the plan and its participants.
Experience has taught me many lessons over the years.
Perhaps the most important is this: don’t underestimate the little things. In retirement plans, they rarely stay little.
