ROBS is equity funding; a 401(k) loan is participant debt
In a plan loan, the participant borrows from a plan that permits loans, signs or accepts an enforceable loan arrangement, receives cash, and must repay principal and interest. The plan’s asset is the participant-loan obligation.[1][3]
In a conventional ROBS arrangement, the prospective owner forms a C corporation, the corporation sponsors a qualified retirement plan, eligible retirement assets roll into that plan, and the plan purchases newly issued employer stock. The plan, not the individual personally, owns the stock. The corporation can then use the stock-purchase proceeds for the operating business.[7][8]
Definitions to settle before comparing dollars
- Participant loan
- A loan from a qualified plan or similar eligible plan to a participant. Plans may offer loans but are not required to do so. IRAs, SEP IRAs, SIMPLE IRAs, and SARSEPs cannot offer participant loans.[1][2]
- Eligible rollover
- A distribution that can be moved to another eligible retirement plan or IRA without current tax when rollover rules are met. Direct rollover and trustee-to-trustee movement avoid the withholding problem that can occur when money is paid to the participant first. Some distributions, including required minimum distributions and loans treated as distributions, are not eligible rollover distributions.[6]
The two journeys use different actors, assets, and documents
A 401(k) loan starts with the existing plan
The participant asks the current plan administrator whether loans are permitted. The controlling documents are the plan document, loan policy, Summary Plan Description, application, promissory note or enforceable electronic agreement, amortization schedule, spousal consent if required, payroll or direct-payment instructions, and later Form 1099-R reporting if the loan fails or is offset.[1][3][4]
A ROBS starts with a new corporate and plan structure
The usual ROBS sequence uses a C corporation, plan sponsor action, a qualified plan and trust, rollover documentation, stock subscription and issuance records, valuation support for employer stock, plan records, corporate bank records, plan filings, participant notices, and ongoing administration. IRS materials emphasize that determination letters review plan terms; they do not bless every later operational step.[7][8][9]
Custody and ownership determine the obligations. With a loan, cash leaves the plan and the participant owes it back. With ROBS, rollover assets move into the new plan trust; the plan trust exchanges them for employer securities; the corporation receives the proceeds. The business owner may control the corporation as an officer or employee, but the retirement plan still owns the shares allocated to the participant’s account.
Loan limits and repayment rules do not become ROBS limits
The general participant-loan ceiling is the lesser of $50,000, adjusted for recent prior loans, or the greater of 50% of the vested account balance or $10,000. A plan may be stricter and does not have to permit the $10,000 exception.[1][2][3]
Repayment generally must fit within five years, use substantially level amortization, include principal and interest, and occur at least quarterly. A longer period may be available for a principal-residence loan; military service and certain leaves can affect timing under specific rules.[1][2][3]
ROBS does not borrow under those loan limits. The practical ROBS ceiling is not a special IRS loan cap; it is the amount of eligible rollover assets that can move to a compatible receiving plan and be prudently exchanged for supportably valued employer stock, after reserving for business working capital, personal diversification, setup costs, administration, and exit risk.[6][7][8]
Reproducible loan-capacity formula
Assumptions: vested account balance = $120,000; no outstanding or recent prior plan loans; plan allows the statutory maximum. Formula: lesser of $50,000 or 50% × $120,000. Calculation: 50% × $120,000 = $60,000; lesser of $50,000 and $60,000 = $50,000. Result: the starting statutory ceiling is $50,000 before plan-specific restrictions, fees, payroll capacity, and administrator calculations.
Tax failures follow different paths
A compliant plan loan is generally not taxable when made. A loan can become a deemed distribution if it exceeds the limit, lacks required enforceable terms, violates repayment-duration or amortization rules, or misses required payments beyond any available cure period. The participant may owe income tax and, depending on age and facts, the additional tax on early distributions.[2][3]
A deemed distribution is not the same as a plan loan offset. A deemed distribution taxes the loan as if distributed but does not necessarily eliminate the debt. A plan loan offset reduces the participant’s account balance to repay the loan and is an actual distribution. Qualified plan loan offsets related to plan termination or severance from employment may have extended rollover timing if the requirements are met.[3][4]
ROBS has no loan payment to default on. Its failure path can involve a failed rollover, impermissible distribution, prohibited transaction, stock valuation problem, discriminatory plan operation, missing Form 5500 or corporate tax filing, inadequate participant access, personal use of corporate funds, or plan disqualification. The IRS ROBS project specifically identified nonfiling, employee-participation problems, promoter fees, valuation issues, business failures, bankruptcies, liens, and dissolutions among examined arrangements.[7][8][9]
Correction also differs. IRS plan-loan correction guidance discusses excess amounts, reamortization, missed payments, deemed-distribution reporting, VCP, SCP, and timing limits for correcting loan failures. ROBS corrections depend on the particular plan, corporate, valuation, tax, fiduciary, and filing failure rather than a single loan-cure formula.[5]
Business impact: payments, ownership, cash flow, and exit
Three reproducible examples
A practical way to choose the next step
Start with threshold facts, not the preferred label. For a 401(k) loan, verify the plan permits loans, the actual vested balance, prior-loan history, repayment method, interest rate, fees, spouse-consent requirements, separation treatment, and cure-period rules. The administrator’s calculation controls the available amount.
For ROBS, verify current distribution availability from the source account, whether the receiving plan can accept the rollover, C corporation fit, stock valuation support, corporate-use restrictions, plan trust custody, employee eligibility, annual filings, ongoing administration costs, and what happens if the business is sold or fails.
A plan loan may fit a smaller need when the existing plan allows enough borrowing and personal cash flow can support repayment. ROBS may warrant evaluation when the funding need exceeds loan capacity, avoiding debt service materially improves business viability, enough retirement diversification remains outside the business, and the owner can maintain a real qualified plan. Neither structure makes a weak acquisition price, thin reserves, or unsupported business plan safer.
Questions worth answering before money moves
Use these questions to gather facts for a plan administrator, CPA, ERISA attorney, valuation professional, lender, or ROBS provider review.
- If considering a loan: Does the plan permit loans; what is the administrator’s available-loan calculation; how are repayments made; what happens after separation; and how would default, deemed distribution, offset, rollover timing, and Form 1099-R reporting work?
- If considering ROBS: Which account is rolling over; when is it distributable; what plan accepts it; who is trustee; what stock is issued; who values the stock; where do proceeds land; how are employees handled; what filings are due; and how would the plan exit its shares?
- If comparing both: How much capital is actually needed after closing costs and reserves; what monthly payment can the owner support; how much retirement diversification remains; what alternatives are available; and what failure path is acceptable?
