Why a 10-Year Exit Plan Matters
Selling your business may be the largest financial transaction of your life. Yet many owners wait until they’re close to retirement, receive an unexpected offer, or face a major life change before they begin thinking seriously about a transition. By that point, your options may be limited.
Research shows that owners who begin business exit planning five or more years in advance often achieve higher sale multiples than those who start within 12 months of their target date.¹ A 10-year runway changes the math. It gives you time to build a business that runs without you, clean up the financials a buyer may scrutinize, and structure the sale around your own tax situation.
Owners who start one or two years out almost always sell for less.² The businesses that command premium valuations tend to be the ones with owners who intentionally prepare — documented systems, recurring revenue, an independent management team, and a tax structure that preserves more of the proceeds.
This guide walks through a 10-year business exit planning framework, broken into five phases, that coordinates financial planning, tax strategy, estate planning, investment management, and insurance into a comprehensive plan.
Years 10-7: Help Reduce Owner Dependence and Build Transferable Systems
Conduct an owner-dependence audit
One of the first and most valuable phases of business exit planning is reducing owner dependence. When your business can’t operate without you, buyers price that risk into their offers. Industry data show that owner-dependent businesses sell at valuation discounts of 15% to 40% compared to companies that have systems and relationships that transfer cleanly.³
An owner-dependence audit asks hard questions:
- Are you the primary business driver?
- Do key client relationships live only with you?
- Does revenue concentration rely on a handful of accounts you personally manage?
If the answer to any of these is yes, that dependence can cost you value.
The goal over these early years is to systematically reduce your role from operator to owner. That may include documenting how the business operates, transferring client relationships to key employees, and building recurring revenue streams that survive your departure.
Document systems and processes
Buyers pay for transferable systems, not your personal effort. Use these years to document systems and processes that a new owner can pick up and operate. A business with clean, documented processes may signal lower risk and influence a stronger multiple.
Years 6-3: Strengthen Your Management Team and Help Optimize Your Tax Position
Build a management team that survives your departure
By years six through three, your focus can shift to building a management team that can run the business independently. Buyers want to see depth — not just a capable second-in-command, but a team that handles operations, sales, and finance independently. This tells buyers your company isn’t built around you. That can help reduce the discount buyers may apply — and lift your sale multiple meaningfully.
This is also the time to address client concentration. If your largest client represents more than 25% of revenue, consider spending these years diversifying your client base or strengthening the contractual foundation of key relationships through multiyear agreements.
Run a QSBS eligibility check
If your business is a C corporation, qualified small business stock (QSBS) under Section 1202 may allow you to exclude a significant portion of your capital gain from federal income tax. The One Big Beautiful Bill Act (OBBBA), signed in July 2025, expanded these benefits substantially.
For QSBS acquired after July 4, 2025, a tiered exclusion now applies: 50% after three years, 75% after four years, and the full 100% exclusion after five years. The maximum excludable gain also increased from $10 million to $15 million per taxpayer, per issuer.
This is why the QSBS check belongs in years six through three — the five-year holding period requirement means you may need to plan well before a sale. If your entity structure doesn’t qualify, this window could give you time to restructure. Coordinate with a tax professional to confirm eligibility, because the rules around qualified small business corporations, active business requirements, and gross asset tests are technical, and mistakes can be costly.
QSBS
| QSBS Acquisition Date | Holding Period | Federal Gain Exclusion |
|---|---|---|
| On or before July 4, 2025 | More than 5 years | Up to 100% |
| On or after July 5, 2025 | At least 3 years | 50% |
| On or after July 5, 2025 | At least 4 years | 75% |
| On or after July 5, 2025 | At least 5 years | 100% |
Excluded gain is subject to per-issuer limits and other QSBS requirements. The taxable portion of gain for partial exclusions may be subject to a higher capital gains rate and net investment income tax.
Optimize financials for buyer scrutiny
Buyers and their advisors may scrutinize three years of financial statements and tax returns. Use this phase to normalize earnings, separate personal and business expenses, and clean up any irregularities. Clear, defensible financials can build buyer trust and help protect your negotiating leverage during due diligence. Aim for normalized earnings before interest, taxes, depreciation, and amortization (EBITDA) with clear add-backs and detailed client retention analytics.4
Years 2-1: Assemble Your Advisor Team and Finalize Presale Estate Planning
Build your advisor team
In the final two years before the sale, if you haven’t already, assemble a coordinated advice team to help guide you. The key is coordination — ensuring tax decisions don’t happen in isolation and that they support your broader wealth objectives.
Mercer Advisors can help ensure every decision — from deal structure to estate planning — aligns with your goals and your family’s future.
One team. One plan. Every stage of your exit.
| We build the transition plan before the process begins | We sit at the table with you when the deal is live | We build the financial life that comes after the exit |
|---|---|---|
| We assemble the right specialists, evaluate your Qualified Small Business Stock (QSBS) position under current Section 1202 rules, establish trust structures, and execute tax elections before the window closes. Every strategy available to you has an expiration date. We help ensure these opportunities don’t go unused. | We join your key deal meetings as your dedicated transition specialist, coordinate tax decisions as terms evolve, and help make sure your wealth plan is ready before the wire clears. Your deal team executes the transaction. We focus on your outcome. | Portfolio strategy, estate documents, tax filing, and a long-term plan: all in place before the proceeds land. Post-exit wealth management with the same team that sat with you through the deal. |
Position your taxes for the sale
The structure of your exit can influence your after-tax proceeds. An asset sale and a stock sale can produce different tax outcomes even with the same headline price. Strategies like qualified small business stock (QSBS) planning, installment sales, or entity restructuring can often require years of preparation to be effective. Use these final two years to model the tax impact of different deal structures and help position yourself for a stronger outcome.
Update your estate plan before the liquidity event
Updating your estate plan before a liquidity event is a strategic move. A business sale significantly changes your asset composition, making the time before the sale ideal to review trust structures, wealth transfer strategies, and beneficiary designations.
Advanced planning techniques can be more effective when implemented before a sale. Consider grantor retained annuity trusts (GRATs), intentionally defective grantor trusts (IDGTs), family limited partnerships, or structured gifting strategies.
If you transfer ownership interests early, you may capture a lower business valuation, which often applies minority interest and lack-of-marketability discounts. That may shift future appreciation out of your estate. If you execute a transfer too close to a liquidity event, the IRS may argue that the estate planning valuation and the sale price should be equal, erasing your tax benefit.
Review insurance and risk management
As you approach the sale, review your insurance coverage and risk management strategy. Buy-sell agreements funded with life insurance, key-person life insurance, and disability insurance may all play a role in protecting the business’s value during the transition. A buy-sell agreement helps ensure the business has a plan if an owner dies, becomes disabled, or retires — and it establishes a valuation mechanism that can reduce disputes. Coordinate with a Mercer Advisors team to align insurance structures with your estate plan and tax strategy so that coverage supports rather than complicates your exit.
Year 0: Execute the Transaction
Structure the deal for after-tax proceeds
Year zero is about execution. With your advisor team in place and your tax and estate planning already structured, the focus shifts to negotiating the transaction, managing due diligence, and closing the deal.
Two transactions with the same headline sale price can produce different outcomes depending on how you structure the deal.
Whether it’s an installment sale, stock redemption, or cross-buy agreement, the structure you choose affects your after-tax proceeds and your post exit flexibility. This is when years of preparation pay off — you enter negotiations with clean financials, a strong management team, and a tax plan already in place.
Postexit: Follow a Diversification Plan
Build an investment strategy
After the sale, your wealth shifts from a single concentrated asset — your business — to a pool of liquid proceeds. That transition feels like diversification, but without a plan, it can drift. An investment strategy defines your allocation targets, risk tolerance, liquidity needs, and rebalancing rules before you make any investment decision. Building that framework in the first 90 days postexit is one of the highest-value activities a Mercer Advisors wealth advisor can help you facilitate.
| Diversified Portfolios | Real Assets | Partial Monetization |
|---|---|---|
| Move earning systematically into a personal brokerage and retirement plan stack so the family balance sheer is not dependent on the sale. | Personal real estate holdings and operating property held outside the business create durable, income-producing wealth. | Recaptializations, minority-interest sales, and insurance-based liqiuidity let you take chips off the table before full exit. |
Deploy proceeds systematically
Rather than investing everything at once, many owners benefit from a staged deployment over 12 to 24 months. This approach, sometimes called a phased diversification plan, helps manage the behavioral and emotional dimensions of transitioning from a concentrated business asset to a diversified portfolio. The goal is to build a mix that fits your goals: equities for growth, fixed income for stability and income, and alternatives or real estate for inflation protection — if they match your liquidity needs.
For years, you may have held 60% to 80% of your net worth in one asset. Now you have both the chance and the responsibility to spread that risk.
Pulling It Together: A Coordinated Approach
A successful business exit isn’t a single decision — it may be a decade of coordinated business exit planning across taxes, investments, insurance, and more. Each phase builds on the last, and each discipline informs the others. Reducing owner dependence may increase your valuation. Tax planning helps preserve more of your proceeds. Estate planning can help ensure your wealth transfers efficiently. A postexit diversification plan helps protect what you’ve built.
The earlier you begin your business exit planning, the more flexibility and leverage you may have. Whether you’re 10 years from a sale or already in the final stretch, the most important step may be the next one.

In an asset sale, the buyer purchases the business’s assets individually, which can create different tax treatment for each asset class. In a stock sale, the buyer purchases the company’s stock, typically producing capital gains treatment for the seller. The suitable choice depends on your entity structure, tax position, and the buyer’s preferences — and the same headline price can yield different after-tax proceeds depending on the structure.
-
A grantor retained annuity trust (GRAT) transfers appreciating business interests to heirs with little or no gift tax if the asset outperforms the IRS rate during the trust term. An intentionally defective grantor trust (IDGT) involves selling business interests to a trust in exchange for a promissory note, freezing the value in your estate while future appreciation grows outside it. Both are most effective if implemented years before a sale, and the suitable choice depends on your growth expectations and cash flow needs.
