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.

TriggerMissed original or extended deadlineCalendar-year plans usually start from a July 31 due date.

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.

Late cases should start with the official IRS relief framework, not the normal on-time packet workflow.
