Business Succession Planning: What Owners Should Consider 5 to 10 Years Before the Sale

Key Takeaways

• Many business owners underestimate how much lead time effective succession planning requires, and the 5-to-10-year window before a transition is often the most valuable planning period available
• A business that has not been formally valued may be worth significantly more or less than the owner assumes, and that gap can have direct consequences for personal retirement planning
• The structure of your business today affects how much of the sale proceeds you keep after taxes, which means restructuring late in the game can be costly and difficult
• Buy-sell agreements and succession documents are often missing or outdated in businesses that have been running smoothly for many years, which can create significant risk for owners and their families
• For many business owners, the business is the largest asset in their personal financial plan, and the two should not be planned for independently

I had a client who had built a successful business and made every financial decision himself for decades. Then his cognitive abilities began to decline.

Years earlier, we had worked together to establish the right legal structures, document a financial plan that did not live only in his head, and build systems that did not rely on his daily involvement. When the time came, the business was successfully sold while he was living with dementia. His wife, who had never been involved in the business, had the income and security she needed without ever being forced into urgent decisions under pressure.

For many business owners, succession planning feels like something to think about later. There is always more to build, more to grow, and more immediate things to focus on.

But if I can leave you with anything, it’s this: plan long before you think you need it.

Why Business Succession Planning Cannot Wait

Business succession planning — the process of preparing your business and your finances for an eventual ownership transition, is one of the most consequential financial decisions a business owner will make. It is also one of the most consistently delayed.

What made the difference in the situation above was not luck or timing. It was the legal structures, financial documentation, and personal planning that had been put in place years earlier, long before anyone knew they would be needed. That is how succession planning works when it works well.

A well-executed transition typically involves:

• Increasing your business value in ways that buyers or successors will pay for
• Repositioning your entity structure for a more tax-efficient sale
• Building the financial documentation and operational independence to make the business attractive to outside buyers

None of these can be done in the months before a sale without significant cost or compromise. The 5-to-10-year window gives you enough runway to make meaningful changes, take advantage of tax strategies that require multi-year execution, and integrate your business transition planning with your personal financial plan in a way that better serves your retirement.

Here is how to start shaping an exit on your own terms:

Consider the Emotional Reality of Succession

For many business owners, the reluctance to plan for succession is as emotional as it is logistical.

Your business is likely the thing you have spent the most time building. It may be tied to your identity, your community, and your sense of purpose in ways that make thinking about a transition genuinely uncomfortable. That feeling is common, and it is worth taking seriously rather than minimizing.

The business owner I described at the opening of this piece had never thought seriously about what would happen to his company if he could no longer run it. The business was his identity. Stepping back was not part of how he saw himself, so planning for it was not something he had done. This is one of the most common reasons succession planning gets delayed.

In my experience, the business owners who take time to consider what the business means to them, and what life looks like without it at the center, are generally better positioned to make transition decisions that hold up over time.

Understanding how a transition may affect your sense of structure and purpose, and what you want to preserve or replace, directly shapes the structure of the exit and the goals the plan is designed to achieve.

Start Your Business Succession Plan with a Formal Valuation

A formal business valuation tells you what your business is worth today, what is driving that value, and what would need to change to increase it meaningfully over the next several years. One of the most common gaps in business succession planning is the absence of one.

Many owners carry a rough number in their head based on industry multiples or what they have heard about comparable businesses. That number is often significantly different from what a formal valuation would produce, and the gap can have real consequences for personal retirement planning.

An owner who discovers their business is worth $2 million when they assumed $4 million has a fundamentally different retirement plan to build. An owner who discovers it is worth $6 million has different options too, including the ability to sell earlier, gift interests to family members over time, or structure a partial sale while retaining equity.

A formal valuation can also surface value gaps: areas where the business may be underperforming relative to its potential. Addressing those gaps over a 5-to-10-year horizon can meaningfully affect what you walk away with at the time of a transition.

Position Your Entity Structure and Tax Strategy Around Your Exit

The way your business is structured today has a direct impact on how a future sale will be taxed. Restructuring close to a transaction can be expensive and may trigger its own tax consequences.

Asset sales and stock sales are taxed very differently, and buyers and sellers often have competing preferences. The entity type you operate under, whether an S corporation, C corporation, LLC, or partnership, shapes the options available to you and the tax treatment of proceeds.

Certain strategies, like positioning for installment sales or taking advantage of qualified small business stock exclusions, require advance planning and specific structural conditions that cannot be created overnight. An owner who has structured their business deliberately over several years may be able to spread sale proceeds across multiple tax years, reducing the overall tax burden significantly. An owner who has not done so may face a concentrated tax event in a single high-income year with limited ability to offset it.

Having this conversation with your financial advisor now, while you still have time to model different scenarios, gives you the ability to make adjustments deliberately rather than reactively.

Protect Your Business with a Current Buy-Sell Agreement

A buy-sell agreement is a legally binding document that establishes what happens to ownership interests in a business if a partner dies, becomes disabled, wants to exit, or faces a divorce or bankruptcy. For any business with more than one owner, it is one of the most important planning documents you can have, and one of the most commonly neglected.

Without a current, well-funded buy-sell agreement, the business and everyone connected to it can be exposed to serious disruption. That disruption can take many forms: a deceased partner’s family claiming an ownership stake, a forced sale at an unfavorable price, or a legal dispute that damages the business and strains relationships at an already difficult moment. The difference between having or not having one in place can mean the difference between a smooth transition and a legal dispute that damages the business, strains relationships, and forces a sale under unfavorable conditions.

Even for sole owners, succession documents matter. Who inherits the business? Who has the authority to operate it in the event of incapacitation? Are key employees aware of the contingency plan? Buy-sell agreements should also be reviewed in the context of how they are funded, typically through life insurance, and whether the coverage amounts still reflect the current value of the business.

Owners who address these issues typically have a clearer path forward regardless of what happens. Those who do not risk leaving the outcome to chance.

Connect Your Business Value to Your Personal Retirement Plan

Succession planning does not stop at the business door. For many owners, the business is the largest single asset in their personal net worth. And yet business planning and personal financial planning are often treated as two separate conversations with limited coordination between them. That separation can be costly.

The years leading up to a transition are among the most valuable for proactive personal financial planning. Owners with significant balances in traditional IRAs, SEP IRAs, or Solo 401(k)s may benefit from Roth conversions during years when business income creates a lower effective tax rate than it will after a sale. Capital gains planning, charitable giving strategies, and the timing of distributions can each affect the total tax burden across the transition period. A business sale that looks clean on paper can carry a significant tax cost if the personal planning has not kept pace.

Running a personal financial plan and a business financial plan on two concurrent paths is how that gap gets closed. A personal plan covers income, retirement goals, tax exposure, protection, and legacy. A business plan focuses on increasing value and positioning for a future transition. Both inform each other, and the decisions made on one path consistently affect outcomes on the other. An owner whose personal assets have been built deliberately alongside the business has more options when the time comes. On the other hand, an owner whose retirement depends entirely on a single transaction has far less room to maneuver.

Frequently Asked Questions about Business Succession Planning

What is business succession planning?

Business succession planning is the process of preparing your business and your personal finances for an ownership transition. It involves determining who will take over the business, how the transfer will be structured, and what financial and legal steps need to be taken in advance to help maximize value and minimize tax exposure. For many business owners, it also involves integrating the expected proceeds from a future sale into a broader personal retirement income plan.

When should a business owner start succession planning?

The 5-to-10-year window before a planned transition is generally one of the most valuable periods for business succession planning. Many of the strategies that can meaningfully improve sale outcomes, including increasing business value, repositioning entity structure, executing Roth conversions, and building personal assets independent of the business, require multi-year execution. Starting earlier creates more options and opportunities to shape the outcome, whereas waiting until a transition feels imminent typically means working around a fixed set of constraints.

What financial steps should I take 5 to 10 years before selling my business?

The financial steps that tend to have the greatest impact in the years before a business sale include: getting a formal business valuation and identifying value gaps, reviewing your entity structure for tax efficiency, beginning proactive business transition planning around Roth conversions and capital gains, ensuring your buy-sell agreement is current and properly funded, and integrating your expected business sale proceeds into a personal retirement income plan. Each of these steps requires time to execute well and can affect both the value you capture at the time of sale and the tax efficiency of the proceeds.

What is a buy-sell agreement and do I need one?

A buy-sell agreement is a legally binding document that governs what happens to ownership interests in a business if a partner dies, becomes disabled, wants to exit, or faces a significant personal legal or financial event. Any business with more than one owner should have one in place. Without it, a partner’s death, divorce, or unexpected departure can create serious legal and financial disruption for the business and the remaining owners. Buy-sell agreements should be reviewed regularly to ensure they are properly funded and that coverage amounts reflect the current value of the business.

How does my business value connect to my personal retirement income plan?

For many business owners, the business represents the largest asset in their personal net worth, which means the expected proceeds from a future sale are often a significant component of their retirement income plan. If that sale is delayed, if the valuation comes in lower than expected, or if market conditions are unfavorable at the time of the transaction, the retirement plan can be materially affected. Building personal assets alongside the business, positioning retirement accounts for tax efficiency during the transition period, and stress-testing the retirement plan against different sale scenarios are all part of connecting the two planning conversations in a way that can help protect the overall outcome.

What are the main exit strategies for business owners?

The main exit strategies for business owners include selling to a third-party buyer, transferring ownership to a key employee or management team, passing the business to a family member, and in some cases executing a partial sale while retaining equity. Each option carries different tax implications, timeline requirements, and personal considerations. The right strategy depends on your financial goals, your priorities for the business after you leave, and how much runway you have to prepare. Our advisors specialize in business succession planning and can help you evaluate which approach fits your situation and build a plan around it.
