ROBS: Using a 401(k) to Buy a Business Without a Penalty

A ROBS, short for Rollover as Business Startup, moves pre-tax retirement money into a new company's retirement plan, and the plan buys stock in that company. The company then spends that cash on the business you are buying. Nothing is withdrawn from a retirement account, so there is no early-withdrawal penalty and no income tax at the rollover, provided the structure is set up and run correctly.

Here is the sequence an advisor walks a buyer through on a first call.

1. You form a new C corporation. It has to be a C corporation because the retirement plan will hold its stock. A pass-through entity does not fit this structure.
2. The corporation adopts a 401(k) plan that allows participants to invest in company stock.
3. You roll pre-tax funds into the new plan from a prior employer plan or an IRA. Whether your current plan allows the rollover depends on that plan's own terms, so you ask the administrator.
4. The plan buys newly issued stock in your corporation at fair market value. The corporation now holds cash.
5. The corporation buys the business. It can be an asset purchase or a stock purchase, depending on how the deal is structured, and you become an employee of the corporation.

Two things make a ROBS different from a loan. There is no interest and no payment schedule, because you are not borrowing. And your retirement savings become shares in a single company, with no diversification and no insurance if the business fails. That risk is the cost of the structure.

The compliance burden is real and it is ongoing. The plan has to be offered to eligible employees, not only to you. The stock has to be valued on a schedule, and the plan has to make its annual filings. The IRS and the Department of Labor both have authority over plans like this, and a plan that skips those steps can lose its tax treatment. That is why buyers use a specialist provider and pay it ongoing fees.

This page gives general information, and you should confirm the structure with your CPA and an attorney who has set up these plans before you roll anything over; they will tell you whether your current plan permits the rollover and how the stock will be valued each year.

A ROBS does not replace the SBA loan; it replaces some or all of your cash, and every SBA threshold still applies to the deal. The rules below come from SOP 50 10 8.1, which governs loans numbered on or after October 1, 2026.

Three points matter most to a ROBS buyer. First, the lender decides how it treats ROBS money, so ask before you pay a provider. Unborrowed cash is an unlimited source under the equity rules, and ROBS funds are your own retirement money placed into the corporation as stock, not borrowed money. Second, expenses for education, advisory services and agent fees paid by the applicant do not count toward the injection, so ask whether your ROBS setup fees fall into that excluded category. Third, the coverage test runs on historical results. Plan administration fees run through the corporation's expenses and are recurring operating costs, so they reduce the earnings a lender uses.

Loans numbered on or before September 30, 2026 stay under the prior SOP 50 10 8, so ask your lender which version governs your file before you build a timeline around it.

Take a $3,000,000 purchase price for a business with $650,000 in SDE, using a 10% injection split into 5% cash and 5% standby seller note. Assume total project cost equals the purchase price. That ignores closing costs and working capital to keep the arithmetic visible, and real project costs run higher because the 10% applies to all of them.

The monthly payment comes from the standard amortization formula: loan times r, divided by one minus (1 plus r) raised to the power of negative 120, where r is 10% divided by 12. The 10% is the maximum variable rate for a loan above $350,000 with prime at 7.00%, so treat it as a stress case. Your negotiated rate may be lower. The 10-year term is the acquisition cap. The $150,000 standby note stays out of debt service because it is on full standby, with no principal or interest paid for the life of the SBA loan, and it is documented on SBA Form 155.

Now the part buyers miss. The $650,000 is SDE, not EBITDA. SDE is net profit plus one owner's full compensation plus documented add-backs. EBITDA is SDE minus a market-rate salary for a replacement manager. The coverage test uses EBITDA. So the $114,785 is the most the salary deduction and any other diligence adjustments can take before the deal misses 1.25x at the 10% stress rate. If a replacement manager costs more than that, you have three levers: a lower price, a larger cash injection, or better earnings. Putting more ROBS cash in shrinks the loan and the debt service, but it also puts more of your retirement savings into one company.

This price also lands on the $3,000,000 Quality of Earnings threshold. The lender will require a report with a cash proof, and it will use the normalized earnings from that report in the coverage calculation. If the report cuts earnings, the $114,785 shrinks. The lender's independent valuation also caps total acquisition debt, and any price above the valuation has to be funded by equity or by debt on full standby.

Run your own price, rate, and earnings through the SBA 7(a) loan calculator to see how much room you have before a lender does.

You negotiate with three parties, the seller, the lender, and your ROBS provider, and your bargaining position differs with each one.

With the seller: the standby note

The 5% standby note asks the seller to wait. No principal and no interest are paid for the entire term of the SBA loan, although interest may accrue and be added to the balance for payment after the SBA loan is repaid. The seller holds the stronger position when other qualified buyers are competing for the business. You hold it when you bring proof of cash and a lender who has issued a term sheet. The note is not refinanced out early. The 36-month seasoning rule applies to seller notes that are paid as agreed, and a note on full standby is not being paid. Read the seller financing guide before you propose terms.

With the seller: timing and certainty

A seller worries about a buyer who needs to finish a plan setup, a stock purchase, and an SBA closing. You counter that worry with documents. Show the rollover funds in an account, show that the lender has started underwriting, and ask for an exclusivity period that covers the independent valuation and the Quality of Earnings report if your price triggers one. Sellers who see bank statements stop treating a ROBS as exotic.

With the seller: the valuation gap

The lender's independent valuation caps total acquisition debt. Write the letter of intent so that a valuation below the price triggers a conversation, either a price adjustment or a larger standby note, before it becomes a failed closing. Your ROBS cash is the flexible source here, but a seller who knows you can plug the gap will not move on price unless the contract says the valuation matters.

With the lender

You bargain over how the lender reads ROBS funds, which account the statements come from, and how the personal guarantee works when a plan-owned corporation is the borrower. Holders of at least 20% ownership generally must guarantee the loan under 13 CFR 120.160(a), and lenders may require guarantees from others. Ask these questions before you pay a provider, while you still have the option to walk away from the structure.

With the ROBS provider

Your position is strongest before you sign. Compare setup fees against ongoing administration fees, and ask who handles the stock valuation and the annual filings. After you sign and roll the funds, switching providers is slow and expensive.

Put the standby note, the valuation clause, and the exclusivity period in the letter of intent, because those three terms decide whether a ROBS buyer or a seller carries the timing risk.

The mistakes below are general failure points in a ROBS-funded acquisition, and each one is avoidable if you catch it before the letter of intent.

• Treating the ROBS as the whole financing. It supplies your cash. The SBA loan still has to pass the 1.25x test, the valuation cap, and the lender's credit review.
• Testing coverage with SDE. The lender uses EBITDA, which is SDE minus a market-rate salary for a replacement manager. A deal that clears at SDE can fail at EBITDA.
• Leaning on projections. Projections may be reviewed, but they cannot be relied on to meet the 1.25x floor. Only the last fiscal year or a two-year average counts.
• Starting the rollover too late. The lender needs statements showing the funds for at least 30 days. A buyer who completes the stock purchase the week before closing has nothing to show.
• Counting setup fees as injection. Education, advisory, and agent fees paid by the applicant are excluded under SOP 50 10 8.1.
• Rolling in every dollar. A business needs working capital after closing. If your retirement balance is the only reserve, one slow quarter can put both the company and your savings at risk.
• Taking deferred maintenance out of earnings. A fleet refresh or equipment replacement found in diligence is a capital item. It comes off the price, not off SDE or EBITDA before the multiple is applied. Only recurring operating costs change earnings.
• Neglecting plan compliance. A plan that excludes eligible employees, skips the stock valuation, or misses its filings can lose its tax treatment, which puts the penalty you avoided back on the table.
• Forming the wrong entity. The plan buys stock, so the entity has to be a C corporation. Settle that with your CPA before you form anything.

A lender and a ROBS provider can each tell you whether your plan is structured correctly, but only your attorney can tell you whether the whole arrangement complies, so bring them into the deal before the letter of intent is signed.

Work through these steps in order, because the first three cost little and tell you whether a ROBS fits your deal at all.

1. Total your rollover-eligible balances. Ask each plan administrator, in writing, whether it allows a rollover into a new plan.
2. Size the deal. Take your target price, compute the 10% injection, and decide how much of it is cash and how much is a standby note. Use the SBA 7(a) loan calculator to test payment and coverage at the 10% stress rate.
3. Call an SBA lender before a ROBS provider. Ask how the lender treats ROBS funds, which account it wants statements from, and how it handles the guarantee for a plan-owned corporation.
4. Engage your CPA and an attorney. They will tell you whether the C corporation, the plan terms, and the stock valuation process are compliant for your situation.
5. Time the rollover. Start early enough that statements show the funds for at least 30 days before closing.
6. Build the target pipeline. Munera's Acquisition Launch sources off-market deals for buyers and introduces lenders, so the financing conversation and the search run in parallel.
