Selling a business can be a once-in-a-lifetime financial event. Most owners pour their energy into the things that feel the most urgent:
- Growing revenue and profitability
- Building a stronger management team
- Improving valuation and market position
- Finding the right buyer and negotiating a deal
All of that matters. But there’s another part of the sale that often gets pushed to the side until it’s “almost time.” And waiting can be extraordinarily expensive.
The blind spot: taxes at the point of sale
Here’s a simplified example that highlights why timing matters.
Assume a business owner sells their company for $50 million. Their tax basis in the business is $500,000.
That’s approximately:
- $49.5 million of taxable gain
Without thoughtful planning, a large portion of that gain may be exposed to federal and state taxes. Depending on the owner’s situation (entity type, state of residency, allocation of purchase price, and other variables), the combined tax bill can be substantial—sometimes well into eight figures.
The real issue isn’t that taxes exist. It’s that many owners don’t run a realistic “deal-day tax estimate” early enough to see what the sale might look like after taxes.
Why “we’ll figure it out later” can cost millions
Once a letter of intent is signed or a deal process is underway, options tend to shrink quickly:
- Negotiating leverage shifts
- Transaction timelines compress
- Structuring flexibility narrows
- Certain techniques may no longer be available if they’re implemented too late
That’s why proactive planning—often well before a sale is on the calendar—can make such a difference.
A strategy many owners overlook: QSBS
One of the most powerful planning concepts for certain founders and early shareholders is QSBS (Qualified Small Business Stock) under Internal Revenue Code Section 1202.
When QSBS applies, it may allow eligible taxpayers to exclude a portion (and in some cases, a significant portion) of capital gains from federal income tax.
QSBS is not automatic—and the rules are strict
QSBS is highly technical. Not every business qualifies, and small details can affect eligibility. In broad terms, common requirements include:
- The company is a C corporation (or becomes one in a qualifying way)
- The company operates an active trade or business (some industries may be excluded)
- The stock is acquired in a qualifying manner (often at original issuance)
- The stock is held for at least five years
- The company meets certain size and asset tests (including limits around gross assets)
If even one piece is missed, the expected tax benefit may not be available. That’s why owners considering QSBS typically coordinate closely with legal and tax professionals.
Where planning can become more advanced: “per taxpayer” opportunities
Another frequently misunderstood QSBS concept is that the exclusion works per taxpayer, not necessarily “per company” or “per deal.”
In certain situations, advanced planning may involve:
- Reviewing how ownership is held
- Considering whether transfers (including to certain trusts) are appropriate well before a sale
- Coordinating estate planning goals alongside tax planning
Important note: Trust planning is not a do-it-yourself project. The rules can be complex, and the tax results can depend on trust design, timing, and how the transaction is ultimately structured.
Don’t forget state taxes: the part that can surprise people
Even if a strategy helps reduce federal taxes, state taxation can still be significant.
Some states conform to federal QSBS rules, others don’t fully conform, and state laws can change. The impact depends on multiple factors, including:
- Your state of residency
- Where the business operates
- Where a trust is administered (when trusts are involved)
- How your state defines taxable income and sourcing
Owners sometimes assume that a federal benefit automatically means the same result at the state level. That assumption can lead to unpleasant surprises.
Rather than relying on a static list of “QSBS-friendly” states, a better approach is to have your CPA (and, when appropriate, specialized counsel) model the expected state impact based on your specific facts.
Timing is everything: planning needs a runway
Many of the most effective strategies—QSBS-related planning, trust structures, charitable planning, installment approaches, or entity restructuring—work best when there is time to:
- Evaluate feasibility
- Document steps properly
- Avoid last-minute decisions under pressure
- Coordinate your CPA, attorney, and wealth advisory team
If you’re within weeks of signing a deal, your choices may look very different than if you’re planning 12–24 months ahead.
A broader toolkit (QSBS may be one piece)
For owners anticipating a liquidity event, planning often involves a combination of approaches, such as:
- Charitable strategies (for those who are charitably inclined) to align giving goals with tax planning
- Installment-based approaches in appropriate cases to spread recognition of gain over time
- Trust and estate planning to align wealth transfer goals with potential tax considerations
- Transaction structuring (e.g., asset vs. stock sale implications, allocation, and negotiations)
The right mix depends on goals: lifestyle needs, legacy planning, philanthropic priorities, and risk tolerance.
The biggest mistake: waiting to ask, “What would my tax bill be?”
Business owners are often surprised by how quickly a sale can move once momentum starts. That’s why one of the most valuable early exercises is simply:
“If I sold today, what would my after-tax outcome likely be?”
That estimate can drive smarter decisions about:
- Entity structure
- Timing
- Valuation targets (what you need to net vs. what you want to sell for)
- Whether advanced planning may be worth exploring
Next step: build your planning team early
If you own a business—or expect a liquidity event in the future—consider starting the conversation now. A coordinated team (you, your CPA, your attorney, and your wealth advisor) can help:
- Evaluate your current structure
- Identify planning opportunities and constraints
- Model potential after-tax scenarios
- Ensure decisions support both your business goals and your long-term financial plan
Tax planning won’t change the fact that a sale is complex—but it can help make sure you keep more of what you’ve spent years building.
