Form 5500-EZ penalties and why the deadline matters

A practical explanation of the penalty risk for missing a required Form 5500-EZ filing.

Summary

Missing a required Form 5500-EZ can create IRS late-filing penalty exposure that accrues by day. The IRS describes a $250 per day penalty, up to $150,000 per plan year, for returns due after December 31, 2019. Solo 5500 Desk is for simple on-time packets, not penalty relief.

Penalty risk is not theoretical

IRS notice guidance describes daily penalties for late or incomplete Form 5500-series filings, and Form 5500-EZ filers are in the IRS penalty lane. That is why a simple plan should still treat the due date as an operational deadline.

Incomplete is not a clean solution

A return with missing or inconsistent information can create its own problem. If the filing is required and records are not ready, evaluate the official extension path rather than filing guessed numbers.

Best first action

Confirm whether the plan exceeded the combined asset threshold or had a final year, then check whether EFAST2 is mandatory. If the answer is yes and the case is simple, prepare the packet before the original or extended deadline.

Common questions

Can Solo 5500 Desk handle a late Form 5500-EZ?

No. The MVP is limited to simple original on-time packets. Late filings, amended returns, IRS notices, and penalty relief questions are outside scope.

What if I already missed the deadline?

Review official IRS late-filer guidance and consider professional help. Do not use an on-time packet tool to create a delinquent filing strategy.

Why does the deadline matter?

A missed required filing can create daily penalty exposure. The strongest prevention step is to confirm the filing trigger, collect records, and prepare before the deadline.
