TL;DR: ROBS (Rollover for Business Startups) lets you use 401(k) funds to buy a dental practice without paying taxes or early-withdrawal penalties. The structure works by forming a C-corp, establishing a 401(k) profit-sharing plan inside it, rolling your existing retirement funds in, and having the plan purchase C-corp stock — which gives the C-corp cash to buy the practice. This is not a loan (no repayment) and not a distribution (no taxes or penalties), but it is a genuine use of your retirement savings and carries real business risk. Best for practitioners with $200,000 or more in qualified retirement assets when SBA down payment funds are a barrier. Critical watch-out for dentists: many states require practice ownership through a Professional Corporation (PC) or PLLC — a C-corp may not satisfy your state’s dental practice act.

ROBS is one of the more misunderstood financing tools in practice acquisition. It is frequently described as “using your 401(k) to buy a business” — which is accurate at the surface level but understates both the structural complexity and the ongoing compliance burden. This guide explains exactly how ROBS works, the dental-specific legal risks that most general ROBS content ignores, and the decision framework for when ROBS makes sense vs when SBA 7(a) is the better path.

What ROBS Actually Is: The Mechanics

ROBS is a five-step corporate and plan structure, not a single transaction:

  1. Form a new C-corporation. The C-corp must be a new entity formed specifically for this transaction. It cannot be an existing LLC or S-corp; ROBS requires the C-corp structure for tax reasons that affect how the plan-to-company equity investment works.
  2. Establish a qualified 401(k) profit-sharing plan (PSP) inside the C-corp. The C-corp adopts a 401(k) plan with IRS-compliant plan documents. This is a real plan governed by ERISA — it must be offered to eligible employees on a non-discriminatory basis.
  3. Roll your existing 401(k) or traditional IRA into the new plan. This is a direct rollover (custodian to custodian), not a distribution. No taxes or penalties apply because the funds never touch your personal account. Note: Roth accounts are generally not eligible — the rollover must come from a traditional (pre-tax) account.
  4. The new plan purchases newly issued C-corp stock at fair market value. The plan uses the rolled-in funds to buy C-corp equity. The C-corp now has cash in exchange for issuing stock to the plan.
  5. The C-corp uses the cash to acquire the dental practice. The C-corp becomes the practice buyer, using the stock-sale proceeds as its acquisition capital. This can be the full purchase price or a partial down payment stacked with an SBA 7(a) loan.

The result: your retirement funds are now invested in C-corp stock, which owns a dental practice. You are not owed a repayment (it is not a loan from the plan to yourself), and no distribution has occurred. But your retirement savings are now concentrated in a single business.

Why Dentists Consider ROBS

ROBS solves a specific problem: the down payment barrier. SBA 7(a) loans for dental practice acquisitions typically require a 10% equity injection from the buyer (approximately $80,000-$150,000 on a typical acquisition in the $800K-$1.5M range). For new graduates or early-career dentists with limited liquidity, that down payment is often the bottleneck — even when income projections and creditworthiness are strong.

ROBS addresses this by converting retirement assets into acquisition capital without incurring debt. Secondary advantages include:

  • No personal credit impact from new debt. The acquisition is funded by the C-corp using plan proceeds, not by a personal loan.
  • Preserved cash liquidity. If ROBS covers the full acquisition cost (or the down payment portion), personal cash reserves remain available for working capital, marketing, or contingencies post-close.
  • Speed relative to SBA underwriting. ROBS setup typically takes 3-4 weeks. That is faster than SBA 7(a) underwriting (60-90 days), though the full acquisition process timeline is similar once both pieces are assembled.

The IRS Compliance Requirements (Ongoing)

ROBS is not a one-time transaction. It creates a live ERISA-governed retirement plan inside your C-corp, with ongoing obligations that must be met every year the structure is active:

  • Annual Form 5500 filing. Required by both the IRS and Department of Labor. The 5500 reports plan assets, participants, and transactions. Failure to file is a significant compliance violation.
  • Annual valuation of C-corp stock. Because the plan holds C-corp stock, the plan’s assets must be valued annually at fair market value. This typically requires an independent business valuation or a defined valuation methodology applied to financial statements.
  • Non-discrimination testing. If you hire employees who become eligible to participate in the 401(k), the plan must pass annual non-discrimination tests (ADP/ACP tests). If dentist-owner contributions are too high relative to other employees, the plan may need to be restructured or additional employer contributions made.
  • Plan document compliance. ERISA plan documents must remain current with IRS guidance. Major law changes (SECURE Act 2.0, for example) require plan amendments.
Disqualification risk: If the plan is disqualified by the IRS for non-compliance, the original rollover is retroactively treated as a taxable distribution plus a 10% early-withdrawal penalty (if you were under 59.5 at the time of the rollover). This is the catastrophic risk scenario. Most ROBS providers include annual compliance maintenance as part of their service model precisely to prevent this.

Dental-Specific Watch-Outs

Most ROBS content is written for franchise and general small business acquisition. Dental practice acquisition has state-law complications that fundamentally change the ROBS analysis:

A. State licensing and ownership structure

Many states require dental practices to be owned by a licensed dentist through a Professional Corporation (PC) or Professional Limited Liability Company (PLLC). A C-corp formed for ROBS purposes is a general corporation and may not satisfy the state’s dental practice act ownership requirement.

The states with specific professional ownership requirements include (but are not limited to) California, Texas, Florida, and New York — four of the largest dental markets in the country. Requirements vary: some states prohibit non-professional-entity ownership outright; others allow workaround structures (an operating agreement between the C-corp and a licensed PC, for example).

Action item: Before spending any money on ROBS setup, consult a dental attorney in your state. If your state prohibits C-corp ownership of dental practices without a licensed-professional exception, ROBS may be unusable for your acquisition without a more complex legal structure.

B. Double taxation in the C-corp structure

C-corps are taxed at the entity level (21% federal corporate rate as of 2026 under the Tax Cuts and Jobs Act). Income that flows out of the C-corp to you personally is taxed again — either as wages (W-2, deductible by the C-corp, subject to employment taxes) or as dividends (not deductible by the C-corp, taxed at qualified dividend rates personally). This is the classic C-corp double-taxation structure that most dental practices avoid by organizing as pass-through entities (S-corps or professional LLCs).

The practical implication: practice cash flow stays in the C-corp. You extract it as a W-2 salary (which is tax-efficient since the C-corp gets a deduction), but the total tax burden on the same dollar of practice profit is higher in a C-corp than in a pass-through structure. Over a 10-year hold, this difference can be material. Model it explicitly with your CPA before committing to ROBS.

C. Exit complexity

Selling a dental practice funded with ROBS adds steps. When the C-corp receives sale proceeds, the money is inside the C-corp. Options for getting it out include:

  • Directing sale proceeds back into the C-corp’s 401(k) plan (the cleanest outcome: retirement-account growth, tax-deferred)
  • Distributing assets as W-2 salary or dividends (taxable, subject to C-corp level tax first on any gain at corporate level)
  • Winding down the C-corp and rolling remaining plan assets into a personal IRA

Most ROBS providers offer exit planning support as part of their maintenance service. Build the exit path into your ROBS decision before you start, not after you decide to sell.

D. SBA lender compatibility

If you plan to stack ROBS (as the down payment) with an SBA 7(a) loan (for the balance), not all SBA lenders will lend to a ROBS-structured entity. Some SBA lenders are uncomfortable with the C-corp structure; others have established ROBS workflows. Guidant Financial and Benetrends both publish guidance on SBA + ROBS combinations and maintain relationships with compatible SBA lenders. Confirm SBA lender compatibility before committing to ROBS if you need both pieces.

ROBS Providers: The Shortlist

ROBS setup is a specialized service. The following providers have established track records (all information based on publicly available sources; verify current pricing and terms directly):

  • Guidant Financial (guidantfinancial.com): Pioneer in ROBS, dental and franchise experience, setup fee starting around $4,999 per published pricing (verify current pricing). Annual maintenance approximately $1,500/year. Established SBA + ROBS workflow.
  • Benetrends Financial (benetrends.com): Rainmaker Plan product, long track record, pricing varies by structure (contact for quote). Also offers SBA lender referrals for ROBS + SBA combinations.
  • Tenet Financial Group (tenetfinancialgroup.com): Dental and franchise focus, similar fee structure to Guidant. Contact for current pricing.
  • FranFund (franfund.com): Franchise and small business focus; dental practice acquisition is within their scope. Contact for pricing.
  • MySolo401k Financial (mysolo401k.net): Lower cost option for solo practitioners; less suited to multi-employee dental practices where non-discrimination testing is more complex.

Get quotes from at least 2-3 providers. Setup fees and annual maintenance fees vary materially, and dental-specific experience matters for state licensing guidance.

When ROBS Makes Sense for Dentists

  • $200,000 or more in qualified retirement assets (traditional 401(k) or traditional IRA, not Roth). Below $100,000, setup costs consume a disproportionate share of the benefit.
  • Your state allows C-corp ownership of dental practices (or has a viable workaround structure confirmed by a dental attorney).
  • You need to preserve SBA loan capacity or personal cash liquidity for working capital post-acquisition.
  • You want to avoid new personal debt and the practice acquisition cost, down payment included, is feasible through ROBS + SBA or ROBS alone.
  • You are early enough in your career to have time to rebuild retirement savings if the practice underperforms. Practitioners within 10 years of retirement should think carefully before concentrating retirement savings in a single business.

When ROBS Does NOT Make Sense for Dentists

  • Your state requires PC or PLLC ownership and prohibits C-corp dental ownership without a workaround. This is a hard stop.
  • Less than $100,000 in qualified retirement assets. Setup costs of $5,000-$15,000 plus annual fees of $1,000-$2,500 consume too large a proportion of the benefit.
  • You are risk-averse about concentrating retirement savings in a single business. ROBS replaces a diversified retirement portfolio with a single-business equity stake.
  • You qualify easily for SBA 7(a) with a manageable 10% down payment. If you have the liquidity or credit profile to clear SBA without using retirement funds, SBA 7(a) keeps retirement savings diversified.
  • You are 55 or older with limited runway to rebuild retirement savings if the practice does not perform as projected.

ROBS + SBA 7(a) Combo (Where State and Lender Permit)

The most common ROBS + SBA structure works as follows:

  1. Use ROBS proceeds as the 10% equity injection (down payment) required by SBA 7(a)
  2. Use an SBA 7(a) loan for the remaining 90% of acquisition cost
  3. Result: lower total debt service than a full-SBA deal, working capital preserved, no personal down-payment loan needed

Example: Practice acquisition price $1,000,000. ROBS funds $100,000 (10% equity injection from retirement assets). SBA 7(a) loan: $900,000. The buyer does not need to put personal cash into the down payment.

Caveat: Your SBA lender must approve this structure. Not all SBA lenders will lend to a ROBS-structured C-corp. Guidant Financial has a published workflow for SBA + ROBS combinations and can refer to compatible lenders. Confirm compatibility before committing to either piece.

Frequently Asked Questions

Can I use my 401(k) to buy a dental practice without paying taxes?
Yes, through a ROBS (Rollover for Business Startups) structure. ROBS is not a withdrawal or a loan from your 401(k) — it is a rollover of qualified retirement funds into a new C-corp’s 401(k) plan, which then purchases stock in that C-corp. The C-corp uses the stock proceeds to fund the practice acquisition. No early-withdrawal taxes or penalties apply because the funds move as a qualified rollover, not a distribution. Ongoing IRS compliance is required to keep the structure valid.
What is ROBS and how does it work?
ROBS stands for Rollover for Business Startups. The structure works in five steps: (1) form a new C-corp, (2) establish a qualified 401(k) profit-sharing plan inside the C-corp, (3) roll your existing 401(k) or traditional IRA into the new plan, (4) the plan buys C-corp stock at fair market value, giving the C-corp cash, (5) the C-corp uses that cash to buy the dental practice. ROBS is legal and IRS-acknowledged, but requires strict ongoing compliance to remain valid.
Is ROBS legal for dental practice acquisitions?
ROBS is legal at the federal level and has been used in tens of thousands of business acquisitions. The IRS has acknowledged ROBS as a legitimate structure when administered properly (see IRS ROBS Project audit guidance). The specific watch-out for dentists: many states require dental practices to be owned by a licensed dentist through a PC or PLLC. A C-corp formed for ROBS may not satisfy that requirement in your state — verify with a dental attorney before proceeding.
What are the ongoing IRS requirements for a ROBS structure?
Maintaining a valid ROBS requires: annual Form 5500 filing with the IRS/DOL, an annual valuation of the C-corp stock held by the plan, compliance with ERISA plan document requirements, non-discrimination testing if employees are eligible to participate in the 401(k), and timely plan contributions. Most ROBS providers handle these requirements as part of their annual maintenance fee. If the plan is disqualified for non-compliance, the original rollover is retroactively treated as a taxable distribution plus a 10 percent early withdrawal penalty.
Can I combine ROBS with an SBA 7(a) loan to buy a dental practice?
In many cases yes. ROBS funds can serve as the equity injection (down payment) required by SBA 7(a), with the SBA loan covering the balance of the acquisition. Not all SBA lenders will lend to a ROBS-structured entity — confirm compatibility with your lender before committing. ROBS providers like Guidant Financial and Benetrends have established SBA + ROBS workflows and can refer to compatible lenders.
What states allow ROBS for dental practice ownership?
ROBS itself is a federal structure and is valid in all states. The state-law issue is dental practice ownership: many states (including California, New York, Texas, and Florida) require dental practices to be owned through a licensed Professional Corporation (PC) or Professional Limited Liability Company (PLLC). A C-corp formed for ROBS may not satisfy those ownership requirements. Some states allow a workaround (operating agreement structures between C-corp and PC); others do not. Consult a dental attorney in your state before setting up a ROBS structure for practice acquisition.
What happens to my 401(k) if the dental practice fails?
If the practice fails and the C-corp goes under, the retirement assets held in the C-corp’s 401(k) plan are at risk — they are invested in C-corp stock, which would be worthless if the business fails. This is the fundamental risk of ROBS: unlike a traditional 401(k) invested in diversified funds, ROBS concentrates your retirement savings in a single business. This is why financial advisors generally caution against using ROBS if you are within 10 years of retirement age or do not have other retirement savings.
How much does it cost to set up a ROBS structure?
ROBS setup typically costs $5,000-$15,000 depending on the provider and complexity. Guidant Financial’s published pricing starts around $4,999 for setup (verify current pricing at guidantfinancial.com). Annual maintenance fees run $1,000-$2,500 per year for plan administration, 5500 filing, and annual valuation. Over a 10-year hold, total ROBS overhead is typically $15,000-$40,000 — compare this against the cost of a down payment loan at market rates to determine which path is more economical.
Should I use ROBS instead of SBA 7(a) to buy a practice?
ROBS and SBA 7(a) solve different problems. SBA 7(a) is a loan — you borrow money and repay it with interest, preserving your retirement savings. ROBS uses your retirement savings directly, eliminating debt but concentrating retirement risk in the practice. ROBS is most compelling when you have $200,000+ in qualified retirement assets and lack the liquidity or credit profile for a conventional SBA down payment. If you qualify easily for SBA 7(a) with a manageable 10 percent down payment, SBA 7(a) is typically the lower-risk path because it keeps your retirement savings diversified.
Can I exit a dental practice that was funded with ROBS?
Yes, but the exit has additional steps compared to a standard sale. When you sell the practice, the C-corp receives the sale proceeds. You can direct those proceeds back into the C-corp’s 401(k) plan (as a stock redemption or contribution), which allows the money to grow tax-deferred — this is the cleanest exit. Alternatively, you can wind down the C-corp, distribute assets to yourself as wages or dividends (both taxable), and roll remaining plan assets into a personal IRA. Most ROBS providers offer exit planning support as part of their maintenance service.
