Estate Planning After a Business Sale: What Founders Should Do First

Why the exit changes your estate planning equation

Privately held business equity has a quirk: minority discounts, lack-of-marketability discounts, and the practical difficulty of transferring a controlling interest mean that the estate tax exposure tied to your company shares was often less than the company's actual value. Once that equity converts to cash and marketable securities, those discounts disappear. Your estate is now larger, more liquid, and easier for the IRS to value.

If your estate was at or below the federal exemption before the sale, it may not be now. If it was already above the exemption, the gap has likely grown. Either way, the inflection point of a business sale is one of the few moments where acting within the first year produces meaningfully different outcomes than waiting.

The good news: the 2026 federal exemption is the largest it has ever been, and recent legislation made it permanent.

The 2026 federal estate and gift tax exemption

The federal estate and gift tax exemption for 2026 is $15 million per person.¹ For a married couple using portability, the combined shelter is $30 million. The top federal estate tax rate on amounts above the exemption is 40%.

The One Big Beautiful Bill Act (OBBBA), signed in July 2025, made this exemption level permanent and indexed it for inflation starting in 2027.² The sunset that was scheduled for the end of 2025—which would have returned the exemption to approximately $7 million per person—did not happen. Estate plans drafted around that sunset scenario should be reviewed to confirm they still reflect your intent now that the higher exemption is permanent.

For founders in the $5M–$30M range, this exemption level means that federal estate tax may not be your most pressing concern right now. But several related planning levers—lifetime gifts, trust structures, and charitable coordination—are still worth deploying while the rules are settled and the window is clear.

The generation-skipping transfer (GST) exemption also matches the $15M figure per person.¹ If you want to pass wealth to grandchildren or future generations without a second layer of transfer tax, the GST exemption is the vehicle and the 2026 amount is the capacity.

Revocable living trusts: the baseline

If you closed a business sale and do not yet have a revocable living trust, that is where the conversation starts. A revocable trust does not provide estate tax protection—the assets inside it are still in your taxable estate—but it does provide three things that matter immediately after a liquidity event:

Probate avoidance. Assets held in a revocable trust pass to beneficiaries without going through probate, which is public, slow, and expensive in many states.
Incapacity planning. The trust names a successor trustee who can manage assets if you become incapacitated—relevant when those assets include freshly-received sale proceeds, earnouts, and post-close adjustments that need someone to manage.
Coordination across asset types. Post-exit, you may hold cash, publicly-traded securities, rollover equity, and earnout receivables across different accounts and structures. A revocable trust provides a single legal owner that simplifies beneficiary designations and estate administration.

Your estate attorney will also update your will (which pours into the trust), your durable power of attorney, and your healthcare directive. If these documents predate the sale, they likely predate the current asset picture and should be updated.

Irrevocable trusts: removing assets from your estate

Irrevocable trusts serve a different function than revocable ones: they remove assets from your taxable estate, often while keeping some economic benefit for you or your family. The tradeoff is that you give up control of the assets once they are inside the trust. The value is that, if structured correctly, they are no longer subject to estate tax in your estate.

For founders post-exit, the most commonly used irrevocable structures are:

Spousal Lifetime Access Trust (SLAT). A SLAT is an irrevocable trust funded with a lifetime gift to your spouse (and indirectly, your children and future descendants). The trust removes the gift from your estate, using your lifetime gift exemption, but your spouse can receive distributions during their lifetime—so the family retains indirect access to the assets. SLATs are particularly well-suited for married founders who want to move significant assets out of the estate now while maintaining some household liquidity.³

Two cautions: SLATs can trigger reciprocal trust problems if both spouses fund separate SLATs for each other at the same time with similar terms. And the "indirect access" disappears if the marriage ends—a risk to account for in the design.

Grantor Retained Annuity Trust (GRAT). A GRAT works differently. You contribute assets and receive a fixed annuity back from the trust for a set term. Any appreciation above the Section 7520 rate during the term passes to beneficiaries estate- and gift-tax free. GRATs work best when you have assets expected to appreciate significantly—such as rollover equity, earnout rights, or publicly traded acquirer stock that you expect will rise.⁴ If the assets do not outperform the 7520 rate, the GRAT zeros out and you get everything back. There is no downside to the grantor; the only cost is the time and legal expense of the structure.

Spousal and dynasty trusts for generational planning. Founders with clear multi-generational intent sometimes skip or complement the above structures with a more permanent trust that names children and grandchildren as beneficiaries and is designed to last for multiple generations. The GST exemption ($15M per person in 2026) funds the structure and shelters appreciation from transfer tax indefinitely in states that allow perpetual or long-duration trusts.

Annual gifts and the exclusion

Beyond lifetime exemption planning, annual gifts use a separate, smaller exclusion that resets every year and does not reduce your lifetime exemption. For 2026, the annual exclusion is $19,000 per recipient.¹ A married couple can give $38,000 per recipient per year.

The arithmetic adds up across a family. A founder with three adult children and four grandchildren could transfer $266,000 per year ($38,000 × 7) with no gift tax return required and no reduction in lifetime exemption. Over a decade, that is more than $2.5M removed from the estate—and that ignores the compounding of investment returns on those gifts outside your estate.

A specific use case worth knowing: 529 education accounts allow five-year gift tax exclusion superfunding. A married couple can contribute $190,000 per beneficiary in a single year by electing to spread it over five years for gift tax purposes, with no annual exclusion or lifetime exemption used.⁵ For founders with younger grandchildren, this is often one of the most efficient early moves.

Charitable giving: donor-advised funds

If you have any charitable intent—current, deferred, or exploratory—establishing a donor-advised fund (DAF) in the year of sale has a specific advantage: you take the income tax deduction in the year you fund it, which is often the highest-income year of your life. The grant decisions (which charities receive the funds, and when) can be made over years or decades at your discretion.

Founders who are not sure where they want to give but know they want a deduction in the sale year often fund a DAF immediately after close and make grant decisions later. The deduction for cash contributions to a DAF is limited to 60% of AGI, with a five-year carryforward for any excess.⁶

Charitable remainder trusts (CRTs) serve a different purpose: they are irrevocable structures that pay an income stream to you (or a named beneficiary) for a term or lifetime, then pass the remainder to charity. They are more useful when the charitable intent is firm and the goal is combining an income stream with a partial deduction, rather than simply accelerating a deduction into the sale year.

Family governance: when to formalize

A family limited partnership (FLP) or family LLC is a structure that consolidates family assets—investment accounts, real estate, alternative investments—under a single entity managed by you or a trust you control, with limited partnership or membership interests distributed to family members. The primary functions are:

Centralized investment management across family members without ceding control
Minority and lack-of-marketability discounts on the interests when gifted—potentially meaningful if combined with annual exclusion gifting
Asset protection, depending on state law and structure
A governance framework for teaching the next generation about family wealth management

FLPs and family LLCs require ongoing maintenance: annual filings, proper capitalization, documented governance, and consistent treatment as a real entity. The IRS scrutinizes them when they appear to exist solely for estate planning benefit without legitimate family business purpose. For founders who already operated a business entity, the discipline is familiar. For others, the administrative overhead can be underestimated at the outset.

Whether this layer is warranted at the $5M–$30M scale depends on asset mix, family complexity, and the specific state discounting and asset protection laws that apply.

Year-one estate planning priorities

Estate planning after a business sale is not an emergency, but it benefits from being treated as a sequenced project with a defined owner. Here is a reasonable first-year scope:

Update or establish your revocable living trust. Retitle accounts and any real estate to the trust. Update beneficiary designations on all financial accounts, retirement accounts, and life insurance.
Review and update your will, power of attorney, and healthcare directive. These should all reflect the post-sale asset picture and your current family situation.
Determine whether your estate now exceeds the federal exemption. If your net worth is under $15M as an individual (or $30M as a couple), federal estate tax is not an immediate issue. State estate taxes may still apply at lower thresholds depending on where you live.
Consider a SLAT or similar structure if meaningful wealth will otherwise sit inside your estate. The discussion should happen in year one because funding an irrevocable trust requires time to document properly and, in some cases, to liquidate or transfer the right assets.
Establish a DAF if you have any charitable intent and close timing made a significant deduction available. The deduction window is the calendar year of the sale.
Begin annual exclusion gifts. Even if larger structures are still being designed, $38,000 per recipient per year starts removing assets from the estate immediately and does not require trust design or complex implementation.
Confirm estate plan ownership with your planning team. After a business sale, you may have a transaction attorney, a CPA, and a financial advisor who are not yet coordinating with your estate attorney. Introduce them and make sure one person owns the checklist.
