You can use your 401(k) to buy a business without paying taxes or the 10% early withdrawal penalty, but only one method actually accomplishes that upfront: a Rollover as Business Startups (ROBS) arrangement. A 401(k) loan avoids the penalty too, within borrowing limits, as long as you keep repaying it on schedule. A straight withdrawal is the fastest option and the most expensive, because it triggers ordinary income tax plus a 10% penalty if you’re under 59½. Each path has real tradeoffs, and the IRS treats ROBS as a high-scrutiny area after finding that most ROBS-funded businesses either failed or were heading toward failure during its compliance reviews.1Internal Revenue Service.

The ROBS Route: No Tax, No Penalty, Strict Rules
A ROBS arrangement moves retirement money into a business you own without a taxable distribution ever occurring. You form a C-corporation, set up a new 401(k) inside that corporation, roll your existing retirement funds into the new plan, and then have the plan buy stock in your own company. The corporation receives cash it can spend on the business. Your retirement plan holds company stock in place of mutual funds.
The structure only works if you follow the rules exactly. It must be a C-corporation, because that is the only entity type authorized to issue the kind of stock a retirement plan can purchase. LLCs and S-corporations do not qualify. The new 401(k) must allow participant-directed investments and must be open to all eligible employees to satisfy federal nondiscrimination rules.2Internal Revenue Service. 401(k) Plan Fix-It Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests
Eligible rollover sources include traditional 401(k) plans, 403(b) accounts, SEP IRAs, and traditional IRAs. Roth accounts don’t work, because the mechanics require pre-tax funds moving into a new traditional 401(k). The transfer has to be a direct rollover from one plan to the other. If the check is made payable to you instead of the receiving plan, the old plan must withhold 20% for federal taxes, and you’ve broken the tax-deferred chain.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Once the funds arrive, the plan buys “qualified employer securities” — employer stock with standard voting and dividend rights — at fair market value. For a new business with no revenue, the valuation reflects the cash and assets being contributed. Buying an existing business typically requires an independent appraisal. After the purchase, the corporation can use the cash to acquire another company’s assets, lease space, buy equipment, cover payroll, or fund operations. You must then work for the corporation as a real employee and pay yourself reasonable compensation, meaning what someone would ordinarily earn for similar work in a similar business.4Internal Revenue Service.

Borrowing From Your 401(k) Instead
If you need less capital and want to keep your retirement account intact, a 401(k) loan avoids taxes and penalties as long as you repay it correctly. The maximum you can borrow is the lesser of $50,000 or 50% of your vested balance, with a floor of $10,000. Someone with a $15,000 vested balance can borrow up to $10,000; someone with $200,000 is still capped at $50,000.5Internal Revenue Service. Retirement Plans FAQs Regarding Loans
Repayment runs on at least a quarterly schedule over five years, with interest usually set a point or two above prime.6Internal Revenue Service. Retirement Topics – Loans The interest goes back into your own account. That sounds clean, but there is a trap for anyone planning to quit their job to run the business. If you separate from employment with a loan outstanding, the balance may be treated as a distribution. You have until your tax filing deadline (including extensions) to roll that amount into another eligible retirement plan.7Internal Revenue Service. Plan Loan Offsets Miss that window and the unpaid balance becomes taxable income, with the 10% early withdrawal penalty on top if you’re under 59½.
So the loan option is genuinely penalty-free only if you stay employed at the sponsoring job long enough to repay it, or if you can scrape together the rollover money from another source after leaving. Neither is a comfortable position when a new business is burning cash.
The Direct Withdrawal Option
Taking money straight out of your 401(k) is the fastest path and the one that almost always triggers the penalty. The plan administrator withholds 20% for federal income taxes when it pays money directly to you.8Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules On a $100,000 withdrawal, you see $80,000; the IRS gets the rest right away. The full $100,000 then gets added to your taxable income for the year, which can push you into a higher bracket. If you are under 59½, you also owe a 10% early withdrawal penalty on the taxable portion when you file.9Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Between withholding, penalty, and state income tax, 35% to 45% of the withdrawal can disappear before a dollar reaches the business.
One narrow carve-out matters for older workers. If you separate from your employer during or after the year you turn 55, the 10% early withdrawal penalty does not apply to distributions from that employer’s qualified plan. This is often called the Rule of 55. It only works for the plan at the job you are leaving, not for IRAs or plans from prior employers, and only if you actually separate from service.9Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions You still owe ordinary income tax on the full amount, but the penalty is gone. For someone in their late 50s leaving a corporate job to buy a business, that can be a meaningful savings.
Why “No Penalty” Isn’t the Whole Story With ROBS
Avoiding the 10% penalty at the front end doesn’t mean the money is unencumbered. A ROBS arrangement creates two overlapping bodies of law that can turn into tax bills if you slip.
The first is the prohibited transaction rules. Your retirement plan and you (as a “disqualified person”) cannot deal with each other in certain ways. You cannot borrow from the plan, lease property to it, or use plan assets for personal benefit.10Internal Revenue Service. Retirement Topics – Prohibited Transactions The business has to operate at arm’s length from the plan that owns its stock. Paying yourself an inflated salary, running personal expenses through the company, or lending company money back to yourself can all trip the rules. If the IRS finds a prohibited transaction, the disqualified person owes an excise tax of 15% of the amount involved for each year the violation is uncorrected. Fail to correct it, and a second tax of 100% applies.11Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions The plan itself can also be disqualified, which converts the entire rolled-over balance into a taxable distribution in the year of disqualification, penalty included if you are under 59½.
The second is annual compliance. The corporate 401(k) has to file Form 5500 every year. Many ROBS owners assume they qualify for the small-plan filing exception that covers one-participant plans with under $250,000 in assets. The IRS has specifically said that exception does not apply to ROBS plans, because the plan owns the business through its stock rather than the individual owning it directly.1Internal Revenue Service. Rollovers as Business Start-Ups Compliance Project Missing the filing costs $250 per day, up to $150,000 per plan year.12Internal Revenue Service. Penalty Relief Program for Form 5500-EZ Late Filers Add periodic stock valuations, the corporation’s own Form 1120, and nondiscrimination testing once you hire employees, and the ongoing compliance load is real.
Professional ROBS providers typically charge $4,000 to $8,000 for setup and $1,200 to $2,400 per year for ongoing administration. Formal stock valuations add cost when triggered.
What Happens If the Business Fails
If the business goes under, the stock your retirement plan holds becomes worthless. There is no insurance backstop and no way to recover the money. The IRS compliance project found that many ROBS participants lost both their retirement savings and their business, with much of the money depleted before the company even started serving customers.1Internal Revenue Service. Rollovers as Business Start-Ups Compliance Project
Winding down requires dissolving the C-corporation and terminating the 401(k) plan. That means filing Form 966 to report the dissolution, a final Form 1120, and a final Form 5500.13Internal Revenue Service. Closing a Business Anything left in the plan after selling business property can be rolled into an IRA. If the failure is complete, “anything left” often means very little.
A ROBS transaction concentrates your retirement savings into a single, illiquid, unproven investment. That is the opposite of standard portfolio advice. It doesn’t make the strategy wrong for everyone, but the penalty-free label at the front end shouldn’t obscure what is really being risked at the back.
