14.2 Retirement Planning for Small Business Owners: Plan Design, Exit Strategies & Concentration Risk
Key Takeaways
- Business owners often have most of their wealth tied up in one illiquid business, so retirement income planning must reduce concentration risk and plan how the business will be converted into income.
- For 2026, a SEP IRA allows employer contributions up to 25% of compensation (maximum $72,000); a solo 401(k) allows $24,500 of elective deferrals plus employer contributions up to the same $72,000 total, before catch-ups; SIMPLE IRA deferrals are $17,000.
- Defined benefit and cash balance plans can allow much larger deductible contributions for older, high-income owners, with a 2026 maximum annual benefit of $290,000, but they require ongoing funding and coverage of eligible employees.
- Common exit paths include a sale to a third party, a family transfer, a sale to key employees, or an ESOP; a C corporation owner who sells at least 30% of the company to an ESOP may be able to defer capital gains under IRC §1042.
- A buy-sell agreement, often funded with life or disability insurance, sets the price and terms for transferring an owner's interest at death, disability, or retirement and provides liquidity for the family.

14.2 Retirement Planning for Small Business Owners: Plan Design, Exit Strategies & Concentration Risk
Core Principle: RICP 354 asks planners to address the retirement needs of the small business owner. Owners face problems employees do not: irregular income, the choice and cost of retirement plans for themselves and their staff, and above all an exit problem, since the business is often their largest asset but produces no retirement income once they stop running it. The retirement plan and the business succession plan must be built together.
The Owner's Unique Retirement Challenges
| Challenge | Why It Matters |
|---|---|
| Concentration | Much of net worth, income, and sometimes real estate depend on one business |
| Illiquidity | A business cannot be sold quickly or in pieces without a buyer and planning |
| Valuation uncertainty | Value depends on the buyer, market conditions, and how dependent the business is on the owner |
| Key-person dependence | A business that cannot run without the owner is worth less and harder to sell |
| Under-saving outside the business | Owners often reinvest profits instead of funding retirement accounts |
| Social Security | Low reported wages (for example, low S corporation salaries) can mean lower future benefits |
Choosing a Retirement Plan (2026 Limits)
| Plan | Best For | 2026 Contribution Limits and Features |
|---|---|---|
| SEP IRA | Owners with few or no employees who want simplicity | Employer-only contributions up to 25% of compensation, maximum $72,000. The same percentage must go to all eligible employees. Compensation up to $360,000 counts. |
| SIMPLE IRA | Small employers (generally 100 or fewer employees) wanting low cost | Employee deferrals $17,000 (catch-up $4,000 at 50+, or $5,250 at 60–63), plus a required employer match (up to 3%) or 2% nonelective contribution |
| Solo 401(k) | Owner-only businesses (plus spouse) | Elective deferrals $24,500 (catch-up $8,000, or $11,250 at 60–63) plus employer profit-sharing contributions, up to a $72,000 total before catch-ups. Roth deferrals and loans may be available. |
| Safe harbor 401(k) | Businesses with employees that want high owner deferrals without nondiscrimination-testing problems | Required safe harbor employer contributions |
| Defined benefit or cash balance plan | Older, high-income owners who want to catch up quickly | Contributions set actuarially. The maximum annual benefit in 2026 is $290,000, which can allow very large deductible contributions for owners in their 50s and 60s. Requires consistent funding and covering eligible employees. |
Planning points:
- Pairing plans: A cash balance plan combined with a 401(k) profit-sharing plan is common for professional practices.
- Roth catch-up rule: Starting in 2026, employees whose prior-year FICA wages exceeded $150,000 must make catch-up contributions to employer plans as Roth. Plans without a Roth option cannot offer those catch-ups to affected employees.
- Timing the exit: Plans must be amended or terminated properly when a business is sold.
Valuing the Business
- Methods: income approaches (capitalized or discounted cash flow), market approaches (multiples of earnings or revenue from comparable sales), and asset-based approaches.
- Owner dependence discount: Buyers pay less for a business whose customers, relationships, or skills leave with the owner.
- Planning horizon: Increasing value often takes 3 to 5 years of preparation: building management depth, clean financial statements, recurring revenue, documented processes, and resolving legal issues.
- Retirement income gap test: Planners should ask, "If the business sold for a conservative price after taxes and fees, would the owner's total resources support the retirement plan?"
Exit Strategies
| Exit Path | How It Works | Retirement Income Considerations |
|---|---|---|
| Sale to a third party | Strategic or financial buyer | Often the highest price. May include an earnout, consulting agreement, or seller note. Asset versus stock sale affects taxes. |
| Family transfer | Sale, gift, or combination to children | Estate and gift planning; fairness to non-business heirs; the owner may depend on the family's ability to pay |
| Management or employee buyout | Key employees buy over time | Frequently seller-financed, which creates credit risk on retirement income |
| ESOP | Employee stock ownership plan buys shares | Can give liquidity and continuity. A C corporation owner selling at least 30% to an ESOP may defer gain under IRC §1042 by reinvesting in qualified replacement property. |
| Liquidation | Sell assets and close | Usually the lowest value |
Taxes on the Sale
- Asset sale: Buyers usually prefer it. The allocation of the price among assets determines the mix of capital gain and ordinary income (for example, depreciation recapture).
- Stock sale: Sellers often prefer it for capital gain treatment.
- Installment sale (IRC §453): Spreads gain over the years payments are received, which smooths taxes but creates buyer credit risk.
- NIIT: The 3.8% net investment income tax applies above the MAGI thresholds ($250,000 joint, $200,000 single). Gain on selling a partnership or S corporation interest is generally excluded to the extent it comes from an active business in which the owner materially participates, but gain on C corporation stock is generally included.
Buy-Sell Agreements and Insurance
A buy-sell agreement establishes who buys an owner's interest, at what price or formula, and on which triggers (death, disability, retirement, divorce, or departure).
| Structure | How It Works | Planning Notes |
|---|---|---|
| Cross-purchase | Co-owners buy each other's interests, each owning a policy on the others | Buyers get a basis increase. Gets complicated with many owners. |
| Entity redemption (stock redemption) | The business buys back the departing owner's interest and owns the policies | Simpler with multiple owners; no basis increase for remaining owners |
| Wait-and-see | Decide the structure at the triggering event | Flexibility |
- Funding: Life insurance for death, disability buyout insurance for disability, and sinking funds or installment notes for retirement.
- Key-person insurance protects the business against losing an essential person, which helps preserve value until the exit.
- Update valuations regularly so the agreed price reflects current value.
Converting the Business Into Retirement Income
After the exit, the owner becomes a typical retiree, often with a large lump sum:
- Plan the tax year of the sale: coordinate Roth conversions, charitable gifts, and IRMAA (two years later).
- Build an income floor (delayed Social Security, annuities) from proceeds if the owner lacks pension-like income.
- Diversify proceeds and avoid re-concentrating in a single investment.
- Manage installment note risk: Treat seller-financed payments as higher-risk income, not as a guaranteed floor.
- Update estate plans to reflect the change from business interests to liquid assets.
Advisor-Client Case Scenario: Ray's Dental Practice
Ray (58) owns a dental practice he expects to sell for about $1.8 million in five years. He has only $350,000 in a SEP IRA, and the practice employs two associates and five staff.
Plan:
- Add a cash balance plan with a 401(k) profit-sharing plan: Actuarial funding allows Ray to contribute far more than the SEP limit each year while providing required contributions for staff, building about $1 million of protected, tax-deferred savings over five years (illustrative).
- Succession: Negotiate a sale to one associate, with a partial seller note and a two-year transition employment agreement. The associate buys term life and disability buyout insurance on Ray, so the purchase can still be completed if Ray dies or becomes disabled before the transition ends.
- Concentration: Stop reinvesting profits in practice real estate. Sell the building with the practice, or lease it to the buyer, keeping in mind the tenant risk.
- Retirement income: At 63, Ray delays Social Security, uses part of the sale proceeds to buy a SPIA covering essential spending, and invests the rest. He treats the seller note payments as discretionary income because of credit risk.
Exam Tip
- 2026 limits: SEP 25% of compensation up to $72,000. Solo 401(k) $24,500 deferral plus employer contributions up to $72,000. SIMPLE $17,000. DB maximum benefit $290,000. Compensation cap $360,000.
- Cash balance or DB plans suit older, high-income owners wanting large deductions but require ongoing funding and employee coverage.
- ESOP §1042: C corporation, at least 30% sold, and reinvestment in qualified replacement property to defer gain.
- Buy-sell: Cross-purchase gives surviving owners a basis step-up; entity redemption is simpler with many owners.
- Seller notes and earnouts are riskier income than guaranteed sources.
