Late Form 5500-EZ filing: penalty relief hard stop
A source-linked hard-stop guide for Solo 401(k) sponsors who missed the Form 5500-EZ deadline and are looking for penalty relief.
Summary
A late Form 5500-EZ is not the same workflow as an on-time packet. Once the original or extended deadline has passed, check the official IRS Late Filer Penalty Relief Program, Form 14704, prior-year filing history, notices, and penalty exposure before submitting anything.
Late filing routes to the official IRS relief review path, not the routine $49 on-time packet.
| Trigger | Missed original or extended deadlineCalendar-year plans usually start from a July 31 due date. |
|---|---|
| Risk | Penalty exposureDo not treat a late return like a normal on-time packet. |
| Official relief path | Form 14704 / Rev. Proc. 2015-32Review eligibility before filing late. |
Why late filing is different
An on-time packet answers a narrow preparation question: should this one-participant plan file Form 5500-EZ, and what values belong in the return? A late case adds penalty exposure, extension evidence, prior-year history and possible notice response. Those facts change the workflow.
Common late-case facts to collect
Collect plan-year dates, year-end asset values, final distribution records, any Form 5558 extension, prior Form 5500-EZ filings, CP214 reminders, penalty letters, EFAST2 records and proof of when the sponsor discovered the issue.
Where the product stops
Solo 5500 Desk can help a simple sponsor understand the normal filing trigger and packet fields. The current paid workflow does not request penalty relief, submit Form 14704, draft reasonable-cause statements, file delinquent-year corrections or respond to the IRS.
Common questions
Can Solo 5500 Desk prepare a late Form 5500-EZ today?
No. The paid product is built for simple original on-time packets. Late filing, penalty relief, prior-year cleanup and IRS notice response need the official IRS late-filer review path or a qualified professional.
What should I check before filing late?
Check whether the return was actually required, whether a timely Form 5558 extension exists, whether a final-year trigger applies, prior filings, IRS notices and the current IRS late-filer relief rules.
Is CP214 the same as a penalty notice?
No. CP214 is a reminder notice. A late-filing penalty or correspondence case needs separate review and should not be handled as a routine packet.
