Using a 401(k) to Buy a Business (ROBS Explained)

What ROBS actually is

A Rollover for Business Startups is not a loan and not a withdrawal. It is a sequence of legitimate transactions that ends with your retirement plan owning stock in a corporation that owns a business. Because the money never passes to you personally, there is no taxable distribution and no 10% early-withdrawal penalty.

The five steps, in order:

• Form a C corporation. The structure requires a C corp specifically, because the plan has to be able to hold qualifying employer securities. An LLC or S corporation will not work — an S corp cannot have a retirement plan as a shareholder.
• The corporation adopts a retirement plan whose documents permit the plan to invest in employer stock. This is a real qualified plan, not a formality.
• Roll your existing funds into the new plan. A 401(k) from a former employer, a traditional IRA, or another eligible account moves in as a direct trustee-to-trustee rollover. Roth accounts are generally not usable this way.
• The plan buys stock in the corporation. The plan now holds shares; the corporation now holds cash. This is the step that should be supported by a valuation.
• The corporation buys the business with that cash — either outright or, more commonly, as the equity injection alongside an acquisition loan.

That last point is where ROBS is most often used well. Funding an entire purchase from retirement savings puts everything on one square. Using $80,000 of rolled funds as the equity injection on an SBA-financed acquisition, while keeping the rest of your savings invested, is a materially different risk posture — and SBA lenders are accustomed to seeing ROBS-funded injections.

What it costs

The sticker cost is modest relative to a business purchase, and the recurring cost is the part buyers underweight.

• Setup: roughly $4,000 to $6,000 to a ROBS provider for entity formation, plan documents, and the rollover mechanics.
• Ongoing administration: roughly $130 to $200 per month for plan recordkeeping, testing, and compliance support. That is $1,500 to $2,400 a year, indefinitely, for as long as the structure exists.
• Corporate tax return: a C corporation files its own return every year, which is a real accounting expense and a real tax posture — profits are taxed at the entity level, and money you take out beyond salary is taxed again as a dividend.
• Form 5500: an annual plan filing once the plan crosses the reporting threshold, with penalties for late filing that are not trivial.
• Valuation: the plan's purchase of stock, and subsequent annual valuations of a plan asset with no public market, should be supported by defensible numbers.

Compare that against a straight distribution. Taking $100,000 out of a 401(k) before 59½ means ordinary income tax on the full amount plus a 10% penalty — a combined bite that can easily exceed $35,000, before considering that the withdrawal may push you into a higher bracket. Against that, $5,000 of setup and $2,000 a year is cheap. The reason to hesitate about ROBS is not its price.

The compliance load is the real cost

The IRS has run a dedicated compliance project on ROBS arrangements, and the recurring findings are instructive: plans that were never actually offered to eligible employees, missing annual filings, promoters' entities that never operated a real business, and valuations that were never performed. The structure is legal; sloppy execution of it is not.

Ongoing obligations worth understanding before you sign anything:

• The plan must be a real plan. If the business has employees who meet the eligibility rules, they must be able to participate — including the ability to invest in employer stock on the same terms. A plan that exists solely for the owner is a classic audit finding.
• You must be a bona fide employee of the corporation, drawing reasonable W-2 compensation. Not a consultant, not an absentee owner.
• No prohibited transactions. No unsecured loans from the company to you, no personal use of company assets, no above-market rent to an entity you control. The penalties for prohibited transactions are severe and can unwind the whole structure.
• Annual filings and annual valuation. Form 5500 when required, and a supportable value for the stock the plan holds.

The worst-case failure mode is not a fine. If the arrangement is disqualified, the rollover can be recharacterized as a distribution — retroactively, with tax, penalty, and interest, on the full amount, at a moment when the money is locked inside a business you cannot quickly sell.

The concentration problem

Set the tax mechanics aside for a moment. A ROBS takes savings that were diversified across an entire market and puts them into a single privately held small business — the same business that is now also your entire income. If it struggles, you lose the paycheck and the retirement account in the same quarter. There is no diversification left to cushion it and no unemployment claim behind a business you own.

That is not an argument against ever doing it. It is an argument for two disciplines. First, do not roll everything: use what the injection requires and leave the rest invested. Second, apply harder diligence than you otherwise would — a business bought with borrowed bank money and a business bought with your retirement are not the same decision, and the diligence checklist deserves to be worked line by line. Confirm the earnings are real and the valuation is defensible before the plan writes a check for stock.

The two alternatives to rule out first

A 401(k) loan. If your current employer's plan permits loans, you can borrow the lesser of $50,000 or half your vested balance and repay it with interest to your own account. No C corporation, no plan administration, no annual 5500, no prohibited-transaction exposure. The limitations are the cap, the fact that plans from former employers usually do not allow loans, and that separating from the employer can accelerate repayment — which matters if the plan is to quit and run the business you just bought. Still: if the gap is $40,000 of an SBA injection, this is the cheaper and simpler instrument.

A straight distribution. Expensive, but occasionally rational — if you are past 59½, the penalty disappears and only ordinary income tax applies, which for a modest amount may cost less than years of ROBS administration. Run the arithmetic rather than assuming.

And the broader alternative: a larger seller note or a smaller target. A buyer who needs a ROBS to reach a deal is sometimes a buyer reaching for a deal one size too large. The down payment math is worth running against a business 30% smaller before you restructure your retirement to buy this one.

If you go ahead

Use an established ROBS provider rather than assembling the structure from templates — the ongoing administration is the product, and the cheap version is cheap because it omits the part that keeps you compliant. Have your own CPA review the arrangement independently of the promoter selling it, because the promoter's incentive ends at setup and yours does not. Keep the plan genuinely available to eligible employees from the first hire. File on time, every year. Pay yourself a reasonable salary through payroll. And keep the annual valuation current, so that when you eventually sell the business and the plan converts stock back to cash, the record supports the numbers.

Done properly, a ROBS is the difference between owning a profitable business at 42 and waiting until you are 60 to have the cash. Done carelessly, it converts a retirement account into a tax bill. The gap between those outcomes is administration, not luck.
