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
The IRS late-filing penalty for Form 5500-EZ is $250 per day, capped at $150,000 per plan year (returns due after December 31, 2019). Example: a calendar-year plan due July 31, 2026 that files on February 1, 2027 (185 days late) faces $250 × 185 = $46,250 in penalties. The IRS Late Filer Penalty Relief Program allows eligible filers to settle delinquent EZ returns for $500 per return capped at $1,500 per submission. Solo 5500 Desk does not handle late filings — review Rev. Proc. 2015-32.

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 the official IRS late-filer penalty relief program, Form 14704, extension evidence and notice history before filing. 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.
