ROBS

What Is a ROBS 401(k)?

Nexus Team · June 10, 2026 · Updated September 10, 2026

A ROBS 401(k), short for Rollovers as Business Startups, is a business funding arrangement in which eligible retirement savings roll into a new 401(k) plan that buys stock in a C-Corporation. The company uses the proceeds to start or buy an operating business. A properly structured and operated rollover avoids a taxable withdrawal, but the retirement savings invested in the business are at risk.

Topic	Short answer
Process	Form a C-Corp, establish its 401(k) plan, complete a direct rollover, and have the plan buy company stock.
Requirements	Eligible retirement funds, an active operating business, a C-Corp, and a bona fide employee role for the founder.
Cost	Providers charge for setup and ongoing administration. See the Nexus pricing page for the published price and included scope.
Timeline	Most cases take roughly two to five weeks, with the sending custodian usually controlling the longest step.
Risk	Retirement savings become concentrated in one private business, alongside ongoing plan and corporate obligations.

How ROBS works

Here's the summary:

You form a C-Corporation
The C-Corp sponsors a new 401(k) plan
You transfer existing eligible retirement funds into the new 401(k) plan
The 401(k) plan purchases shares in the C-Corp
The C-Corp has operating capital. The 401(k) plan holds the equity

Now the detail:

1. Form a C-Corporation

ROBS requires a C-Corp. LLCs and S-Corps aren't eligible. This is a legal constraint, not a provider preference: the exemption applies to qualifying employer securities, and in practice only C-Corp stock qualifies.

Formation means articles of incorporation, bylaws, an EIN, a registered agent, and a board that authorizes the stock issuance. Founders buying an existing business typically form the C-Corp as the acquiring entity. The C-Corp structure can unlock meaningful tax planning, including QSBS, for those who qualify. Covered in The Case for C-Corps.

2. The C-Corp sponsors a 401(k) plan

The C-Corp adopts a new 401(k) plan with its own plan documents, trust, and trust EIN. This is a real retirement plan. It must cover eligible employees, operate for the benefit of participants, and run under ERISA standards.

3. Roll over eligible retirement funds

You direct a rollover from existing eligible retirement accounts into the new 401(k) plan. When done properly, because funds move directly between qualified accounts, nothing is distributed, nothing is taxed, and nothing is penalized.

Eligible sources generally include 401(k) balances from former employers, traditional IRAs, 403(b) and governmental 457(b) plans, the Thrift Savings Plan, SEP IRAs, and SIMPLE IRAs after their two-year holding period.

4. The 401(k) plan purchases stock

The 401(k) plan uses the rolled-over funds to buy newly issued shares of the C-Corp for adequate consideration. This is the legal heart of the transaction. The 401(k) plan trust becomes a shareholder, the C-Corp receives the cash, and the issuance is documented: board resolutions, a stock purchase agreement, a cap table.

The price has to be right. For a new corporation with no operating history, value is often the cash going in. When used to acquire an existing operating company, an independent valuation is how the plan demonstrates it paid fair market value.

5. The C-Corp deploys the capital

The C-Corp now spends the money to either acquire a business, or as operating capital: signing a lease, buying equipment, hiring, funding inventory.

The money belongs to the C-Corp. It does not belong to you personally, and that distinction is permanent. Using corporate funds for personal expenses is not allowed.

ROBS 401(k) requirements and fit

Potential fit if you:

Have $50,000 or more in rollover-eligible retirement savings
Want to start or acquire a business using your own retirement funds
Will actively work in the business as an employee

Not ideal if you:

Have less than $50,000 in retirement savings
Seek a business that generates passive income
Are uncomfortable putting retirement savings at risk

The business must be a real operating company: active, for-profit, legal at the federal level. Restaurants, franchises, trades, manufacturing, software, acquisitions of existing companies.

ROBS pros and cons

Pros

Business capital without loan payments or interest on the ROBS funding.
Eligible savings can fund a startup, acquisition, or franchise.
A properly executed rollover avoids cashing out retirement savings.

Cons

You can lose the retirement savings invested in the business.
The C-Corp and 401(k) plan require ongoing administration and filings.
Setup and recurring fees reduce the capital available for operations.

What does it cost?

ROBS has two cost categories: initial setup and ongoing administration. Nexus charges $5,000 for setup and $500 per quarter for administration. See the pricing page for the complete included scope and provider comparison.

How long does it take?

Typically weeks. The C-Corp and the 401(k) plan can be established in days. The variable is the rollover itself, which depends on how quickly the current custodian releases funds; most complete a direct rollover in one to two weeks.

Nexus typically takes a founder from application to funded in 2 to 3 weeks. Industry-wide, 3 to 5 weeks is common.

What are the ongoing requirements?

For as long as the plan owns stock, the obligations recur.

The 401(k) plan must file Form 5500. The plan must complete required testing. The plan must hold an ERISA fidelity bond. The corporation must stay in good standing: registered agent, annual reports, franchise taxes. The cap table and valuation records must stay current. Eligible employees must be offered participation as you hire. Compensation must stay reasonable, and prohibited transactions must stay avoided.

All of it has to happen, and someone has to own it. That is the standard to hold any provider to, including us.

Risks worth knowing

The IRS guidance on ROBS describes filing failures, valuation problems, and restrictions on employee participation. It also reported serious business failures and retirement losses among the businesses examined. These findings are a reason to assess both business risk and ongoing compliance before moving funds.

Concentration. Retirement savings move from diversified funds into one private company. This is the fundamental investment risk.

Compliance failure. The IRS has discovered ROBS structures that stopped being administered: no Form 5500, no valuation, prohibited transactions. The consequence of a disqualified plan is severe, since the original rollover can become a taxable distribution with penalties.

Prohibited transactions. The 401(k) plan and the people who run the company are disqualified persons with respect to each other, and the law strictly limits dealings between them. Paying personal expenses from corporate funds. Lending company money to yourself. Leasing your own property to the company. The map is in our guide to prohibited transactions.

Business failure. Worth separating from everything above. If the business fails, the plan's stock loses its value. The failure is not, by itself, a tax event or a violation. The structure unwinds in order: dissolve the C-Corp properly, file the plan's final Form 5500, roll remaining plan assets out to an IRA.

Common questions

Is ROBS a loan?

No. In a ROBS arrangement, the 401(k) plan purchases company stock. The company receives equity capital, so the ROBS funding itself has no loan repayment schedule or interest. The plan can lose its investment if the business fails.

How is ROBS different from a 401(k) loan?

A 401(k) loan lets a participant borrow from a plan that permits loans, subject to repayment terms and plan-loan limits. ROBS uses a rollover into a new plan that purchases C-Corp stock. It creates an equity investment in the business rather than a participant loan.

Is ROBS legal?

ROBS can be lawful when structured and operated in compliance with retirement-plan and corporate requirements. The IRS scrutinizes these arrangements; a favorable determination letter addresses the plan document, not whether the business operates the plan correctly.

What is the minimum amount of retirement savings for ROBS?

There is no legal minimum. As a practical matter, $50,000 or more in eligible funds is where the structure's fixed costs can start to make sense.

Can I use a Roth IRA for ROBS?

No. Roth IRA funds cannot be rolled into a 401(k) plan, so they cannot fund a ROBS transaction.

Can I use my current employer's 401(k)?

Usually not while you still work there, since most plans do not permit in-service rollovers before age 59 and a half. Former employers' plans and traditional IRAs are the typical sources.

Do I have to pay myself a salary?

Yes, you must pay yourself a reasonable W-2 salary, for work performed, once the business is operating and can support it.

How long does a ROBS rollover take?

End to end, Nexus typically takes founders from application to funded in 2 to 3 weeks. Industry standard is 3 to 5 weeks.

Can ROBS be used with an SBA loan?

Yes. ROBS may supply equity alongside an SBA loan, subject to the lender's requirements. See the ROBS and SBA acquisition guide.

Can ROBS fund a franchise purchase?

Yes. ROBS can be used to capitalize an eligible franchise operating through the required C-Corporation structure.

The Bottom Line

If you have meaningful retirement savings, ROBS can be a powerful funding path for you to capitalize a business using your retirement funds. Make sure the structure is set up correctly and maintained properly from the start.

If your goal is to buy a company rather than start one, compare the full capital stack in the founder funding guide. When you are ready to test the fit, complete the Nexus prequalification before moving funds or making a provider commitment.
