Business succession planning has always involved more than deciding who gets the company when the founder retires or dies.

A good plan has to answer practical questions:

• Who will control the business?
• Who will own the equity?
• How will a buyout be funded?
• How will taxes be paid?
• How will the plan actually be enforced?

Those questions became even more important after the 2025 federal tax law, commonly known as the One Big Beautiful Bill Act, or OBBBA.

OBBBA did not invent business succession planning. It did not eliminate the need for careful buy-sell agreements, trust planning, valuation work, or estate tax analysis. What it did was make several important tax rules more durable under current law, while leaving major estate tax traps in place.

For business owners, that creates both opportunity and risk. The opportunity is that certain income tax and capital gain planning rules are now more stable. The risk is that a poorly designed succession plan can lock in tax consequences that may be difficult or impossible to fix later.

This article is a general educational overview. It is not legal, tax, or financial advice. Business succession planning is highly fact-specific and should be reviewed with qualified legal, tax, valuation, and financial advisors.

Why OBBBA Matters for Business Succession Planning

The law commonly called OBBBA made several tax rules especially important for business owners.

Three areas matter most for succession planning.

1. Section 199A, the qualified business income deduction, was made permanent under current law. This deduction can allow eligible owners of pass-through businesses to deduct up to 20% of qualified business income.
2. Section 1202, the qualified small business stock exclusion, was expanded for certain C corporation stock issued after July 4, 2025. This can be extremely valuable for founders, investors, and business owners who qualify.
3. The federal estate, gift, and generation-skipping transfer tax exemption was increased to $15 million, adjusted for inflation, beginning after 2025. That gives many business owners more room to transfer wealth, but it does not eliminate estate tax risk.

The key point is this: OBBBA made several planning rules more favorable, but it did not make succession planning simple.

Business owners still have to deal with valuation, control, liquidity, income tax, capital gains, trust design, family dynamics, and estate tax inclusion.

What Business Succession Planning Is Really Trying to Do

A business succession plan should not be just a stack of documents.

It should be a practical operating plan for what happens if the founder dies, retires, becomes disabled, exits the company, or wants to transfer ownership over time.

A strong plan should answer four core questions.

1. Who controls the business during the founder’s lifetime?
2. Who owns the business after death, retirement, or exit?
3. Where will the cash come from to fund buyouts, taxes, and family obligations?
4. How will the plan be enforced if family members, business partners, or successors disagree?

Common succession structures include:

• Redemption buy-sell agreements;
• Cross-purchase buy-sell agreements;
• Hybrid buy-sell agreements;
• Management buyouts;
• Family transfers;
• Trust-owned business interests;
• Installment sales;
• Gifts of nonvoting interests;
• Recapitalizations;
• Life-insurance-funded buyouts.

These tools can work well. But they must be coordinated.

The problem is that many business owners sign documents without fully understanding how those documents interact with income tax, capital gains tax, estate tax, control rights, and future liquidity needs.

Governance Documents Can Become Tax Evidence

For business owners, the operating agreement, shareholder agreement, buy-sell agreement, trust agreement, employment agreement, and management agreement are not just business documents.

They can also become tax evidence. If the founder claims to have transferred ownership but still controls distributions, compensation, liquidation decisions, voting power, trustee appointments, or sale timing, the IRS may argue that the founder did not really give up the business interest for estate tax purposes.

This is especially important under Internal Revenue Code Section 2036, which can bring transferred property back into a taxable estate if the person who made the transfer retained possession, enjoyment, income, or certain powers over who benefits from the property.

In plain English, the IRS may ask:

• Did the founder really give up control and economic benefit?
• Or did the documents say one thing while the business continued to operate as if nothing changed?

That question can determine whether the transferred business interest is excluded from the founder’s estate or pulled back into it at death.

Gifts vs. Sales: The First Major Decision

Business owners often transfer company interests in one of two ways: by gift or by sale.

Each option has different tax consequences. A gift may use part of the owner’s lifetime gift and estate tax exemption. A sale may avoid using an exemption, but it can trigger capital gain or create installment payment issues.

Neither method is automatically better. The right choice depends on the business, the owner’s goals, cash flow, valuation, family circumstances, and tax exposure.

Why a Completed Gift May Not Be Enough

A transfer may be complete for gift tax purposes but still cause estate tax problems later.

That surprises many business owners. A founder may sign documents transferring shares or membership interests to children, a trust, or other successors. The gift may be reported. A valuation may be obtained. A gift tax return may be filed.

But the analysis does not necessarily end there. If the founder continues to control the business, receive economic benefits, direct distributions, control liquidation, or depend on the transferred assets, the IRS may argue that the founder retained enough control or enjoyment to cause estate inclusion under Section 2036.

The label “gift” does not control the result. The real question is whether the founder’s legal and economic relationship to the business actually changed.

Why Lifetime Sales Can Help, But Only If They Are Real

A lifetime sale can sometimes reduce Section 2036 risk because Section 2036 contains an exception for a bona fide sale for adequate and full consideration.

In general terms, this means the transaction must be real, supported by value, and motivated by legitimate non-tax purposes.

In a business succession context, legitimate purposes may include:

• Keeping the business operating after the founder exits;
• Transitioning management to the next generation;
• Resolving ownership disputes;
• Creating a buyout structure among active and inactive family members;
• Protecting business continuity;
• Separating voting and economic interests;
• Providing liquidity for the founder’s retirement;
• Creating enforceable rules for future ownership.

But a sale is not automatically respected just because documents call it a sale.

The payment terms must be realistic. The buyer must have the ability to pay. The founder should not retain so much control that the transaction only works if the founder continues running the business.

The Installment Sale Problem

Many closely held business succession plans use installment sales.

That often happens because the next generation, management team, or trust does not have enough cash to buy the founder’s interest outright.

Instead, the buyer signs a promissory note and pays the founder over time.

Installment sales can be useful, but they create a practical problem: the founder may worry that the buyer cannot make the payments unless the founder stays involved.

That leads to the “protect the note” problem.

The founder sells the business interest but keeps control to make sure the business generates enough cash to pay the note.

That may make business sense, but it can create tax risk.

If the transaction only works because the founder retains control, the IRS may argue that the founder never really gave up the transferred interest. Depending on the facts, the IRS may claim retained enjoyment, retained control, or a retained power over beneficial enjoyment.

The safer approach is to structure the sale so the payment arrangement, security, governance, management transition, and business operations do not depend on the founder quietly keeping control after the transfer.

S Corporations and the Capital Gain Constraint

Many closely held businesses are S corporations.

That matters because S corporation succession planning is often constrained by income tax and capital gain rules.

When S corporation stock is sold, gain generally flows through to the shareholder level. Depending on the owner’s basis, value, and deal structure, the tax cost can be significant.

S corporation stock also does not qualify for the Section 1202 qualified small business stock exclusion because Section 1202 applies to qualified stock issued by a C corporation.

That does not mean S corporations are bad. They can be excellent entities for many businesses.

But it does mean an S corporation owner usually cannot assume that the business will qualify for QSBS treatment. If a founder is thinking about converting from S corporation to C corporation status to pursue Section 1202 benefits, that planning needs to happen carefully and early.

Section 1202: Powerful, But Not for Every Business

Section 1202 can be one of the most powerful tax benefits available to founders and investors.

For qualified small business stock issued after July 4, 2025, OBBBA expanded Section 1202 in several important ways.

The law allows a partial exclusion after shorter holding periods and a full exclusion after a longer holding period, if all requirements are met. For post-OBBBA qualified stock, the exclusion is generally:

• 50% after a three-year holding period;
• 75% after a four-year holding period;
• 100% after a five-year holding period.

OBBBA also increased the gain exclusion cap to the greater of $15 million or 10 times the taxpayer’s basis in the stock for eligible post-enactment stock. The corporate gross asset limit was also increased from $50 million to $75 million for certain purposes.

Those are meaningful changes.

But Section 1202 is not available to every business owner.

In general, the stock must be issued by a C corporation. The company must satisfy active business requirements. The stock must be acquired in a qualifying original issuance. Certain industries do not qualify. Holding period rules matter. Redemptions and other transactions can create problems.

For business succession planning, the main point is this:

Section 1202 can be valuable, but it must be planned for before the exit is already underway.

S-to-C Conversions Require Caution

Some S corporation owners may consider converting to C corporation status to pursue Section 1202 benefits.

That may be worth exploring, but it is not a simple fix.

A conversion close to a sale may not produce the intended result. Section 1202 has original issuance, holding period, and active business requirements. If a conversion and sale are part of a prearranged plan, tax authorities may examine whether the steps should be viewed together rather than separately.

That concern is often described as step-transaction risk.

In simple terms, the IRS may ask whether the separate steps were really independent, or whether they were all part of one plan to reach a tax result.

The practical lesson: do not wait until a buyer is at the table to begin QSBS planning.

Section 199A: The Pass-Through Deduction Is Now More Durable

Section 199A allows eligible owners of pass-through businesses to deduct up to 20% of qualified business income.

This can apply to owners of S corporations, partnerships, LLCs taxed as partnerships, sole proprietorships, and some trusts or estates.

OBBBA made the Section 199A deduction permanent under current law.

That matters because many business succession plans involve pass-through entities. If the plan accidentally reduces or eliminates the deduction, the tax cost may continue year after year.

• Business succession planning can affect Section 199A in several ways.
• It may change who owns the business.
• It may change compensation.
• It may create guaranteed payments.
• It may shift income to trusts.
• It may affect aggregation of related businesses.
• It may change wage or qualified property calculations.
• It may involve a specified service trade or business, where income thresholds can limit or eliminate the deduction.

This does not mean Section 199A should control every succession decision. But it should be reviewed before ownership is transferred or compensation is restructured.

Founder-Centric Businesses Need Extra Attention

Some businesses are built heavily around the founder’s personal reputation, relationships, name, image, likeness, skill, or professional services.

These businesses may face additional Section 199A limitations, especially if they fall within the specified service trade or business rules.

Examples may include certain law firms, accounting firms, consulting businesses, financial advisory firms, medical practices, performing arts businesses, athletics-related businesses, and businesses where the principal asset is the reputation or skill of one or more owners or employees.

The issue is not simply whether the business is profitable.

The issue is whether the type of income qualifies for the deduction and whether the owner’s taxable income exceeds the relevant thresholds.

For succession planning, this matters because a founder-centered business may need to transition not only equity, but also client relationships, management responsibility, brand value, and income streams.

Section 2036: The Estate Tax Trap Business Owners Cannot Ignore

Section 2036 is one of the biggest estate tax risks in business succession planning.

It can apply when a business owner transfers property during life but retains certain benefits, control, income rights, or powers over who enjoys the property.

This is especially important for founders who transfer business interests to children, trusts, family entities, or successor owners but continue to act as if they still own the business.

The IRS may look at facts such as:

• Who controls distributions;
• Who controls compensation;
• Who can force or block a sale;
• Who can liquidate the business;
• Who controls voting rights;
• Who appoints or removes trustees or managers;
• Who depends on the business for personal expenses;
• Whether the founder retained practical control after the transfer.

Section 2036 risk is not limited to abusive planning. It can arise when business owners try to transition ownership but do not fully separate control, economics, and governance.

Management Agreements and Continued Control

A founder may continue working for the business after transferring ownership.

That is not automatically a problem.

Many businesses need the founder’s experience during a transition. A consulting agreement, employment agreement, or management agreement may be appropriate.

But the arrangement should reflect real services and reasonable compensation.

If the founder transfers ownership but keeps broad operational control, excessive compensation, or authority unrelated to actual services, the IRS may argue that the founder retained enjoyment or control of the transferred business interest.

The distinction matters.

A founder can be paid for real work.

A founder should not use a management agreement as a substitute for continued ownership control.

Trustees, Distribution Committees, and Fiduciary Control

Many succession plans use trusts.

Trusts can protect younger beneficiaries, preserve family control, provide asset protection, and help coordinate estate tax planning.

But trusts must be designed carefully.

If the founder can remove and replace trustees with related or subordinate people, direct distributions, control investment decisions, or influence fiduciaries who are not truly independent, the IRS may argue that the founder retained indirect control.

The trust may look separate on paper, but the IRS may ask whether the founder can still control who receives economic benefits and when.

Independent fiduciary design, trustee removal powers, distribution standards, and governance rules should all be reviewed closely.

Liquidity Control Can Be Estate Tax Control

Control over liquidity can be extremely important.

A business may not produce cash unless distributions are made, assets are sold, the company is refinanced, or the business itself is sold.

If the founder retains the ability to decide when those liquidity events happen, the founder may retain practical control over when beneficiaries receive economic value.

This can create Section 2036 risk, especially if the founder can act alone or together with others to cause liquidation, block distributions, or determine when value is released.

For succession planning, liquidity rights should be addressed directly.

• Who can approve a sale?
• Who can force a redemption?
• Who can authorize distributions?
• Who can amend the operating agreement?
• Who can borrow against business assets?
• Who can liquidate the company?

These are not merely business questions. They are also estate tax questions.

Do Not Give Away Everything

One recurring estate tax problem occurs when a founder transfers too much.

If the founder gives away business interests or other assets but remains financially dependent on the transferred property, the IRS may argue that there was an implied understanding that the founder would continue to benefit from those assets.

That can support estate inclusion under Section 2036.

A founder should generally retain enough personal assets, income, and liquidity to support living expenses, taxes, health care, and foreseeable needs.

A succession plan is weaker when the founder has no realistic way to live unless the transferred business continues providing personal financial support.

Legitimate Non-Tax Purposes Matter

Tax planning is a valid part of business succession planning.

But tax reduction should not be the only purpose.

A stronger succession plan usually has real business and family reasons, such as:

• Business continuity;
• Management transition;
• Keeping ownership within the family;
• Protecting employees;
• Reducing disputes among children;
• Separating voting and economic rights;
• Providing liquidity for inactive owners;
• Preparing for retirement;
• Creating a buyout mechanism;
• Preserving customer and vendor relationships.

The more the plan reflects real business needs, the easier it is to defend.

The more it appears to exist only to reduce estate tax while leaving the founder in control, the greater the risk.

Gift Tax Disclosure Does Not Solve Section 2036

Filing a gift tax return is important.

Adequate disclosure on a gift tax return can help start the statute of limitations for certain gift tax issues, including valuation.

But it does not necessarily protect the estate from Section 2036 at death.

The IRS may still examine whether the transferred property should be included in the founder’s estate because the founder retained control, enjoyment, income, or powers over the property.

This is one of the most misunderstood points in succession planning. A gift can be reported. A valuation discount can be disclosed. The statute of limitations may run on certain gift tax issues. And the estate may still face a Section 2036 argument later. That is why the structure must be correct from the beginning.

SLATs, Spouses, and Divorce Risk

Some business owners use spousal lifetime access trusts, commonly called SLATs.

A SLAT allows one spouse to transfer assets to a trust that may benefit the other spouse. This can preserve indirect family access while moving assets outside the transferor’s estate if the trust is properly structured and administered.

SLATs can be useful, but they carry risks.

One major risk is divorce.

If a couple divorces after a SLAT is created, the trust may no longer function as expected. Divorce proceedings may also create evidence about who really controlled the trust, whether the transferor expected continued access, and whether the arrangement was understood as a way to preserve indirect benefit.

That does not mean SLATs should be avoided in every case.

It means they should be drafted and administered with care.

The trust should not depend on informal understandings, assumed spousal cooperation, or continued access that undermines the estate tax planning.

Post-nuptial agreements may be relevant in some cases, but they also require careful state-law review. Courts may scrutinize these agreements closely, especially if one spouse lacked independent counsel, meaningful disclosure, or informed consent.

Reporting, Disclosure, and Audit Survival

A business succession plan should be designed with audit survival in mind.

That means the documents, valuation, tax reporting, governance, and actual conduct should all tell the same story.

• If the plan says the founder gave up control, the governance documents should support that.
• If the valuation assumes minority ownership or lack of control, the founder should not retain practical control through side agreements.
• If the trust is supposed to be independent, fiduciaries should act independently.
• If the business has a buy-sell agreement, the pricing and funding mechanics should be realistic.
• If the transfer is reported as a gift or sale, the economic terms should match the reporting.

The IRS will not look only at one document. It may look at the whole arrangement.

Practical Planning Questions for Business Owners

Business owners should review their succession plan in light of OBBBA and continuing estate tax rules.

Important questions include:

• Does the plan clearly identify who will control the business if the founder retires, dies, or becomes disabled?
• Does the buy-sell agreement still work?
• Is the valuation formula current and defensible?
• Is life insurance needed to fund a buyout?
• Are installment sale payments realistic?
• Does the founder retain too much control after a transfer?
• Does the plan rely on Section 199A assumptions that may not hold after ownership changes?
• Could Section 1202 apply if the business is or becomes a C corporation?
• Would an S-to-C conversion create more problems than benefits?
• Are trusts designed as owners of business interests?
• Are trustees and fiduciaries truly independent?
• Does the founder have enough personal liquidity after making transfers?
• Do the documents match how the business is actually operated?

These questions are not theoretical. They often determine whether a succession plan works in practice.

The Bottom Line

OBBBA changed the tax landscape for business succession planning, but it did not remove the need for careful planning.

Section 199A is now a more durable benefit for many pass-through business owners, but succession planning can still disrupt the deduction.

Section 1202 became more powerful for qualifying C corporation stock, but many closely held businesses, especially S corporations, will not automatically qualify.

The estate and gift tax exemption increased to $15 million, adjusted for inflation, under current law, but Congress can always change the law later.

Most importantly, Section 2036 remains a major estate tax risk.

A business owner cannot simply transfer equity on paper while keeping the same control, economic benefit, and practical authority as before.

Effective business succession planning requires real substance:

• Real transfer of ownership;
• Real governance changes;
• Real liquidity planning;
• Real fiduciary independence where needed;
• Real non-tax business purposes;
• Real separation between what the founder used to own and what the founder still controls.

The best succession plans do not merely reduce taxes. They prepare the business, the family, and the ownership structure for what comes next.
