Is Solo 5500 Desk legit?
A trust and scope page for Solo 401(k) owners checking whether Solo 5500 Desk is the right self-preparation tool for a simple Form 5500-EZ packet.
Summary
Solo 5500 Desk is independent self-help software for simple, original, on-time Form 5500-EZ packet preparation. It is not the IRS, DOL, EFAST2, a filing transmitter, law firm, CPA, EA, ERPA, TPA, fiduciary, or plan administrator. Use it only when your records are ready and the case stays in the owner-only lane.
Legit use case: simple on-time packet preparation, not official filing or professional advice.

What Solo 5500 Desk actually prepares
The product organizes a narrow packet for simple one-participant Solo 401(k) Form 5500-EZ cases: filing trigger, deadline, sponsor identity, plan number, year-end asset values, contributions, distributions, loan fields, filing-method prompt, source checklist, and annual passport.
What it does not do
It does not transmit through EFAST2, sign forms, store Login.gov or EFAST2 credentials, file Form 5558, request penalty relief, answer IRS notices, act as a TPA, provide legal/tax/ERISA advice, or decide whether a complex plan design is compliant.
Why the tool is intentionally narrow
Form 5500-EZ looks short, but the risky part is deciding whether the case belongs in the one-participant lane. Narrow scope is a safety feature: the app should stop when the facts require official instructions, a TPA, CPA, EA, attorney, ERPA, fiduciary, or plan professional.
Official-source posture
The product copy is built around IRS Form 5500-EZ instructions, IRS late-filer guidance, Form 5558, Form 14704, Revenue Procedure 2015-32, and DOL EFAST2 help. Official sources control when there is a conflict.
How to trust the output
Do not trust any packet blindly. Compare the packet to year-end statements, prior filings, plan records, extension records, EFAST2 or mailing evidence, and official instructions. If a field is uncertain, stop before filing.
When a professional is the better answer
Use a professional for late years, amended returns, notices, penalty letters, missing prior filings, employees, controlled group or affiliated service group questions, participant loan corrections, nonzero liabilities, hard-to-value assets, or any question that asks what you should do rather than how to organize known facts.
