- Professional 3(38) investment oversight
- No AUM fees
- Transparent, flat-fee pricing

User Sentiment Analysis
Rates highly (4/5) for "Peace of Mind." The fact that a third-party administrator is keeping the books provides a compliance safety net that self-administered plans lack. However, the nickel-and-diming on loan fees and monthly billing model are detractors.
Strategic Insights
- Unique positioning as TPA + recordkeeper provides audit protection most providers cannot offer
- If your business grows to hire employees, transition to full 401k is seamless—Ubiquity already handles enterprise plans
- 3(38) fiduciary investment oversight without AUM fees is a rare benefit
- SECURE 2.0 compliant with sophisticated contribution logic for Age 60-63 enhanced catch-ups
Market Position
Ubiquity offers a unique value proposition as a 401(k) recordkeeper that offers a Solo product. Unlike "document providers" (who give you paperwork and leave) and "brokerages" (who hold assets), Ubiquity maintains the records. This appeals to users terrified of IRS audits. The third-party administrator role provides a compliance safety net that self-administered plans lack.
Target Audience: Business owners who prioritize compliance safety, want professional oversight, and may eventually hire employees—especially those "terrified of IRS audits"
Watch Out For
- Loan fees add up: $100 setup + $100 annual maintenance on top of base pricing
- Checkbook control only available in Plus tier ($350 setup / $37.50 monthly)
- Base tier limited to CensiblyYours fund list—no brokerage window
- Monthly fee structure adds up over time
- Mega Backdoor Roth requires specific selection during onboarding
Feature Comparison
Compliance Notes
Includes Form 5500-EZ preparation. Professional recordkeeping provides stronger audit defense than self-administered plans.
Full Review
Ubiquity takes a different approach than most Solo 401k providers by functioning as both a third-party administrator (TPA) and recordkeeper, with professional investment oversight included.
Their Single(k) plan starts at just $285 setup and $19/month - the lowest entry point among non-prototype providers. The Single(k) Plus tier at $350 setup and $37.50/month adds additional features.
A unique feature is their 3(38) fiduciary investment oversight with the CensiblyYours fund list and model portfolios. This provides professional management without the typical AUM (assets under management) fees that other advisory services charge.
The Single(k) Plus tier adds important capabilities: checkbook control for alternative investments and the option to add Mega Backdoor Roth. Note that participant loans come with additional fees ($100 setup and $100 annual maintenance).
Where Ubiquity shines is scalability. If your business grows and you eventually hire employees, transitioning to a full 401k plan is seamless since Ubiquity already handles enterprise-level retirement plans.
Key Features
- Traditional, Roth, and After-Tax contributions
- Mega Backdoor Roth (optional add-on)
- Checkbook control (Plus tier)
- Participant loans
- Professional investment oversight
- Model portfolios available
- No AUM fees
- Recordkeeping included
- Scalable to full 401k
Who Is This Best For?
Those who prioritize compliance and professional oversight, prefer a hands-off approach, or plan to eventually add employees to their business.
