Use Your 401(k) to Buy a Business (ROBS): Risks & Costs

Using Your 401(k) or IRA to Buy a Business (ROBS): How It Works, What It Costs, and Whether It's Worth the Risk

If you're looking at buying a business and your biggest pool of available capital is sitting in a retirement account, you've probably come across something called ROBS - Rollover for Business Startups. The pitch sounds almost too good to be true: use your 401(k) or IRA to fund a business acquisition without paying early withdrawal penalties or income taxes. No debt. No monthly loan payments. Just your own money, moved from a retirement account into a business you own and operate.

ROBS is real. It's legal. The IRS recognizes it. And thousands of people have used it to buy businesses across the country, including here in Atlanta. But it is not simple, it is not cheap to set up, and it carries a level of risk that most of the companies selling ROBS services gloss over in their marketing.

This guide breaks down exactly how ROBS works, what it costs, where it makes sense, and where it can go very wrong. If you're thinking about using your 401(k) or IRA to buy a business, read this before you sign anything.

HOW ROBS ACTUALLY WORKS

ROBS is not a loan. You're not borrowing from your retirement account. And it's not a withdrawal - you don't pay the 10% early withdrawal penalty or income taxes that would normally apply if you pulled money out of a 401(k) before age 59 and a half.

Instead, ROBS uses a specific legal structure that allows you to invest your retirement funds into a business you own and operate. Here's the step-by-step:

Step 1: You form a new C-corporation. This is not optional - the business must be structured as a C-corp for ROBS to work. LLCs and S-corps don't qualify.

Step 2: The C-corporation establishes a new 401(k) retirement plan. This is a qualified plan under ERISA, just like the 401(k) you had at your previous employer.

Step 3: You roll over your existing 401(k) or IRA funds into the new C-corp's 401(k) plan. This is a trustee-to-trustee transfer - no taxes, no penalties, because the money is moving from one qualified retirement plan to another.

Step 4: The new 401(k) plan uses its funds to purchase stock in the C-corporation. Your retirement plan is now an investor in the company.

Step 5: The C-corporation now has cash from the stock purchase. You use that cash as the down payment for the business acquisition, working capital, or both.

The result: your retirement money is now invested in a business you own and operate, and you didn't pay taxes or penalties to access it. The IRS allows this because your retirement plan is making an investment - buying stock in a company - which is something retirement plans are allowed to do.

WHAT DOES ROBS COST TO SET UP?

ROBS is not a DIY project. You need a specialized provider to handle the legal structure, plan documents, compliance filings, and ongoing administration. Here's what the costs typically look like:

Setup fees: $3,000 to $6,000 for the initial C-corp formation, 401(k) plan creation, plan documents, and rollover processing. Some providers charge more. Be suspicious of anyone charging less than $2,000 - the compliance work is real and cutting corners here creates IRS audit risk.

Ongoing administration: $100 to $200 per month for plan administration, compliance monitoring, annual reporting (Form 5500), and DOL requirements. This is not optional. ROBS plans are qualified retirement plans under ERISA, which means they have the same annual reporting and fiduciary requirements as any other 401(k). If you stop paying for administration and miss your filings, you have a compliance problem with both the IRS and the Department of Labor.

Tax preparation: C-corporations file their own tax returns (Form 1120), which is separate from your personal return. Expect to pay your CPA an additional $1,000 to $3,000 per year for the corporate return, on top of your personal filing.

Total first-year cost: roughly $5,000 to $10,000 in setup and administration fees, plus ongoing annual costs of $2,500 to $5,000 for plan administration and tax prep.

These costs are real and recurring. Factor them into your financial projections before deciding if ROBS makes sense for your deal.

WHERE ROBS MAKES SENSE

ROBS isn't inherently good or bad. It's a tool, and like any tool, it works well in certain situations and poorly in others.

ROBS works well when you have substantial retirement savings (typically $50K minimum, and ideally $100K or more) that you can invest without wiping out your entire retirement safety net. If your 401(k) has $400K in it and you're rolling $150K into a business while keeping $250K invested for retirement, that's a very different risk profile than rolling your entire $80K balance into a business and hoping it works out.

ROBS works well when the alternative financing options are worse. If you can't qualify for an SBA loan because of credit issues, insufficient collateral, or an unconventional deal structure, ROBS may be your only realistic path to ownership. In that case, the question isn't "is ROBS risky?" - it's "is ROBS less risky than not buying the business at all?"

ROBS works well as a complement to other financing, not as the sole funding source. The strongest ROBS deals I see use the rollover as the equity injection (down payment) for an SBA loan. You roll $100K from your 401(k) into the C-corp, use that as your 10% down payment on a $1M acquisition, and finance the rest through SBA. You've accessed your retirement money penalty-free, and the SBA loan provides the bulk of the purchase price. This hybrid structure reduces risk because you're not betting your entire retirement on the business.

ROBS works well when you're buying a business with strong, predictable cash flow. If the business can service itself - covering your salary, the ongoing ROBS administration costs, and generating profit on top of that - then the retirement funds you invested are working harder inside the business than they were sitting in an index fund.

WHERE ROBS GOES WRONG

Here's the part that ROBS providers don't put on their websites.

If the business fails, your retirement is gone. This is the fundamental risk. When you invest retirement money in a publicly traded index fund, the worst realistic scenario is a market downturn - you lose 30% or 40% and it recovers over time. When you invest retirement money in a small business, the worst scenario is total loss. The business closes, the cash is gone, and your retirement account is empty. There's no FDIC insurance, no market recovery, no do-over. For someone in their 40s or 50s, losing their retirement savings leaves very little time to rebuild.

C-corp tax treatment is a real cost. C-corporations are subject to double taxation - the corporation pays income tax on its profits, and then you pay personal income tax again when those profits are distributed to you as dividends. S-corps and LLCs (which are the standard structures for small businesses) avoid this by passing income through to the owner. With ROBS, you're locked into the C-corp structure, and the ongoing tax inefficiency is a real drag on your returns.

Some ROBS providers will tell you that you can convert the C-corp to an S-corp after a certain period, or that there are workarounds to minimize double taxation. These strategies exist but they're complex, they have their own IRS compliance risks, and they need to be managed carefully by a CPA who understands ROBS structures.

IRS scrutiny is real. ROBS transactions are legal, but the IRS has flagged them as an area of compliance concern. The IRS Employee Plans division has conducted multiple studies and audits of ROBS arrangements. If your plan isn't administered properly — if you miss Form 5500 filings, if the plan fails nondiscrimination testing, if the stock valuation isn't defensible - you could face penalties, plan disqualification, or both. Plan disqualification means the entire rollover gets reclassified as a taxable distribution, and you owe income taxes plus the 10% early withdrawal penalty on the full amount. On a $200K rollover, that's potentially $70K or more in taxes and penalties.

You must pay yourself a reasonable salary. As an employee of the C-corp, you're required to take a "reasonable salary" - and you have to pay payroll taxes on it. You can't skip your salary to preserve cash in the business, and you can't set it artificially low. The IRS defines "reasonable" based on what someone in your role and industry would earn. If you're running a $1M revenue business and paying yourself $30K, that's going to raise flags.

Your retirement plan must benefit all eligible employees, not just you. This is the ERISA requirement that catches many ROBS business owners off guard. If you have employees who meet the plan's eligibility requirements (typically age 21 and one year of service), you're required to offer them participation in the 401(k) plan. And the plan has to pass non-discrimination testing, which means you can't just contribute for yourself while ignoring everyone else. This adds cost and complexity, especially as the business grows and hires more people.

ROBS VS. OTHER FINANCING OPTIONS

Before committing to ROBS, compare it against the alternatives:

SBA 7(a) loan: 10-20% down payment required, 10-year terms, interest rates tied to prime. The down payment can come from personal savings, gift funds, or a smaller ROBS rollover. This is the standard path for most business acquisitions and should be your first option if you qualify. For a full breakdown, see our guide on SBA loans for buying a business.

Seller financing: Many sellers will finance 10-30% of the purchase price, which reduces your cash needed at closing. Seller financing combined with an SBA loan can get you into a business with relatively little out-of-pocket cash.

Home equity: If you own a home with substantial equity, a HELOC or home equity loan can fund your down payment. The interest rates are typically lower than ROBS administration costs, and you maintain your retirement savings intact.

Personal savings: The simplest option. No structural complexity, no administration fees, no C-corp tax headaches. If you have enough liquid savings to cover the down payment and working capital without touching retirement funds, that's almost always the better path.

ROBS should be a last resort or a strategic complement - not your default financing strategy.

QUESTIONS TO ASK A ROBS PROVIDER

If you decide ROBS is the right tool for your situation, vet your provider carefully. Here's what to ask:

How many ROBS plans have you set up? Look for providers with hundreds or thousands of plans, not a handful.

What's your IRS audit track record? A reputable provider should be able to tell you how many of their plans have been audited and what the outcomes were.

What does ongoing administration include? Make sure it covers Form 5500 filing, nondiscrimination testing, plan amendments, and compliance monitoring - not just a document binder you're expected to manage yourself.

What happens if I want to convert to an S-corp later? Understand the process, the timeline, and the tax implications before you commit.

What's your fee structure? Get the full picture: setup, monthly administration, annual filings, and any transaction fees. Compare at least three providers before choosing one.

Do you provide a written opinion letter? Some providers offer a legal opinion confirming the plan's compliance with IRS and DOL requirements. This is valuable protection in the event of an audit.

THINKING ABOUT USING YOUR 401(K) OR IRA TO BUY A BUSINESS?

ROBS can be a legitimate path to business ownership - but it's not the right path for everyone. If you're considering it, the first step is understanding all of your financing options side by side, not just the one that sounds easiest.

I work with buyers across the Atlanta metro who are evaluating acquisition opportunities and trying to figure out the right way to pay for them. Whether ROBS, SBA, seller financing, or some combination makes sense for your deal depends on the specific business, your financial situation, and your risk tolerance. Let's talk through it.
