Hiring your first employees? Once someone becomes eligible, a solo 401(k) no longer works. Here’s how to move to a full plan without losing your savings power.
Keep your contributions. Add your team the right way.
A free plan transition review for your business
A solo 401(k) is only for owners and their spouses. Once an employee meets your plan’s eligibility rules, the plan has to cover them, and most solo 401(k) providers can’t administer a plan with employees.
The good news: you don’t have to give up your contribution levels. A properly designed employee 401(k), with profit sharing and, if it fits, a cash balance plan, can keep most of the contributions with you while giving staff a fair benefit.
Continuing to fund a solo plan after an employee becomes eligible can cause the plan to fail IRS coverage rules, which is costly to fix.
From first call to first contribution, we handle the design, the math, and the compliance.

Only until that employee becomes eligible under the plan’s rules. After that, the plan must cover them, so it needs to become a full 401(k) with a provider that supports employees.
A 401(k) can generally require employees to be age 21 and complete one year of service with 1,000 hours. Long-term part-time employees with 500+ hours in two consecutive years must be allowed to defer.
Often yes. A custom design with profit sharing, and possibly a cash balance plan, can keep most contributions with the owners while giving staff a fair benefit.
No. A spouse who works in the business can participate in a solo 401(k) without disqualifying it.
The plan can fail IRS coverage rules, which can require corrective contributions for the excluded employee and fees to fix. It’s much cheaper to transition before eligibility.
Usually a few weeks. We review your current plan, design the new one, coordinate the asset move, and set up payroll integration.
Sometimes. Many solo 401(k) programs can’t support employees, but some recordkeepers can work with your preferred custodian or investments. We’ll show you which options fit.
