Estate Planning for Business Owners: The 2026 Guide

Most business owners have estate plans written for people who don't own businesses — generic wills that ignore the hard problem: 70–90% of your net worth is a single illiquid asset that can't easily be divided, can't be sold quickly without destroying value, and requires a buyer at the exact moment your estate needs cash. This guide explains what a real estate plan looks like when a business is in the middle of it.

Why business owners need a different kind of estate plan

A business owner's estate has structural problems that a W-2 employee's estate doesn't:

• Concentration risk. If your business is worth $3M and your other assets (home equity, retirement accounts, brokerage) total $500K, your estate is 86% illiquid. Heirs may owe estate taxes before they can sell anything.
• Valuation uncertainty. The IRS will assign a fair market value to your business interest for estate tax purposes. The number it lands on may differ from what you think the business is worth — and the difference creates tax liability, not a refund.
• Liquidity crisis. Federal estate tax (if applicable) is due within 9 months of death. If there's no plan for liquidity, a forced business sale is often the result — at distressed prices, on a compressed timeline.
• Operating continuity. Who runs the business while the estate is being settled? Who makes decisions? A well-drafted estate plan answers these before a crisis, not during one.

These problems are solvable, but solving them requires planning that's specific to business owners — not a generic will from an online document service.

The 2026 estate tax landscape: the permanent $15M exemption

The One Big Beautiful Bill Act (OBBBA), signed in July 2025, permanently raised the federal estate and gift tax exemption to $15,000,000 per person — up from $13,990,000 in 2025.¹ Before OBBBA, this exemption was scheduled to sunset to roughly $7M at the end of 2025. That sunset no longer happens.

For most business owners, the $15M exemption means federal estate tax is not the primary concern — unless your business, real estate, and liquid assets combined exceed $15M (or $30M for a married couple). State estate taxes are a separate issue. States like Massachusetts, Oregon, and Washington have exemptions as low as $1–2M, and rates up to 20%.

Even if your estate is under the federal threshold today, the exemption should be used strategically — through lifetime gifts, trusts, and charitable giving — before inflation and business growth push you above it.

Business interests in your estate: how they're valued

The IRS values privately-held business interests using a hypothetical willing-buyer, willing-seller standard. For a minority interest in a family business, this almost always results in a valuation below the pro-rata share of the business's enterprise value — for two reasons:

• Lack of marketability discount. A private business interest can't be sold on an exchange. A hypothetical buyer will pay less for it. Typical discounts: 15–35%.
• Minority interest discount. A non-controlling interest can't direct business decisions. Additional discount: 10–25%.

Combined, discounts of 25–45% on the FMV of the enterprise are defensible with a qualified appraisal. This can meaningfully reduce estate tax exposure — but the discounts only apply to interests that are actually minority interests in a properly structured entity.

If you own 100% of an S-corp and die owning 100% of it, there's no minority discount. If you've transferred 49% to family members or a trust during your lifetime, your remaining 51% still commands a control premium — but the 49% you transferred gets the minority discount. The planning is in the lifetime transfers.

The estate liquidity problem: ILITs and life insurance

The most common solution to the estate liquidity problem for business owners is an Irrevocable Life Insurance Trust (ILIT). Here's how it works:

1. You establish an ILIT — a separate irrevocable trust — and name your heirs as beneficiaries.
2. The ILIT buys a life insurance policy on your life. Because the trust owns the policy (not you personally), the death benefit is excluded from your taxable estate under IRC § 2042.²
3. You make annual gifts to the ILIT to cover premium payments. These gifts qualify for the annual exclusion ($19,000 per beneficiary in 2026) if the trust document includes proper Crummey withdrawal rights — a 30-day window in which beneficiaries can demand the gift before it funds the premium.
4. At your death, the ILIT receives the tax-free insurance proceeds and uses them to purchase assets from your estate or loan cash to it — providing liquidity without a forced business sale.

The critical requirement: the ILIT must be irrevocable and cannot be controlled by you. If you retain incidents of ownership over the policy (the right to change beneficiaries, surrender the policy, or borrow against it), the death benefit is included in your estate.

For a business owner with a $5M business and $500K in liquid assets, a $3M ILIT-held policy might cost $8–15K per year in premiums (age and health dependent) and solves a liquidity problem that would otherwise require a fire-sale exit.

Annual gifting: building wealth outside your estate

Every year, each person can give $19,000 to any number of recipients without gift tax consequences and without reducing their lifetime exemption.¹ A married couple can give $38,000 per recipient per year. For a business owner with three adult children and six grandchildren, that's $38,000 × 9 = $342,000 per year out of the estate with no tax consequence, no paperwork, no exemption usage.

Common structures for annual exclusion gifting by business owners:

• Direct cash or stock transfers. Simplest. Give cash or appreciated securities. The recipient takes your cost basis on gifts (unlike inheritances, which get stepped-up basis).
• §529 superfunding. Front-load 5 years of annual exclusions into a 529 plan in one year — $95,000 per recipient (or $190,000 for a couple). No additional exclusion gifts to that beneficiary for 5 years. Treated as if made ratably over 5 years for gift tax purposes.³
• ILIT premium payments (see above) — annual exclusion gifts fund the trust, which funds the insurance premiums.
• Fractional business interests. Gift minority interests in the business annually. Combined with valuation discounts, a $19K face-value gift is worth more than $19K in enterprise value after discounts — every dollar of gift moves more than a dollar of value out of your estate.

GRATs: transferring business appreciation tax-free

A Grantor Retained Annuity Trust (GRAT) lets you transfer the appreciation of your business interest to heirs at no gift or estate tax cost. Here's the mechanic:

1. You transfer business interests (or other appreciating assets) into the GRAT.
2. The GRAT pays you an annuity for a fixed term — typically 2–5 years. The annuity is sized so the present value of all annuity payments equals the value of the asset you transferred (a "zeroed-out GRAT"). Gift tax on transfer: zero.
3. If the trust assets appreciate faster than the IRS hurdle rate — the § 7520 rate, currently approximately 4.6% — the excess appreciation passes to heirs gift-tax-free at the end of the term.⁴

GRATs work best when: (1) interest rates are moderate or lower — a lower § 7520 rate means a lower hurdle; (2) the underlying asset is expected to appreciate significantly; and (3) you survive the GRAT term (if you die during the term, the assets revert to your estate). For business owners with rapidly growing businesses or who are approaching an exit event, GRATs can transfer substantial value at no transfer tax cost.

Charitable strategies: DAF and Charitable Remainder Trusts

Donor-Advised Fund (DAF)

A DAF is the simplest charitable giving vehicle for business owners. You contribute cash or appreciated assets, take an upfront charitable deduction at FMV, and distribute to qualified charities over time. Contributing S-corp stock or LLC membership interests to a DAF is complicated (the DAF can't own S-corp stock without triggering UBTI), but cash or publicly-traded securities work cleanly. The primary appeal: contribute in a high-income year (the year before a business sale, for example), claim the full deduction when your marginal rate is highest, and distribute grants later.

Charitable Remainder Trust (CRT)

A CRT is more powerful for owners with a large concentrated exit event:

1. You contribute appreciated business interests (or stock) to the CRT before the sale.
2. The CRT sells the asset — no capital gains tax at the time of sale, because the CRT is tax-exempt.
3. The CRT pays you (and optionally a spouse or other income beneficiary) an income stream for life or a fixed term — typically 5–10% of the trust's initial value per year.
4. At the end of the term, the remainder passes to charity.

You get an upfront charitable deduction equal to the present value of the charitable remainder interest. The income stream from the CRT is taxable as received, but the initial sale is tax-deferred — the full pre-tax proceeds are reinvested in the trust, generating a larger income base than you'd have after paying capital gains on the full amount upfront. CRTs are particularly effective for older owners who want income, a reduced estate, and a charitable legacy — and are planning a sale event where a large capital gain is unavoidable.

Retirement accounts: the estate planning wildcard

Retirement accounts (IRA, Solo 401(k), SEP-IRA) don't get a stepped-up cost basis at death — they're Income in Respect of a Decedent (IRD). Your heirs pay ordinary income tax on every dollar they withdraw, on top of any estate tax the account contributed to. This makes retirement accounts the worst assets to leave to taxable heirs and the best assets to leave to charities (which pay no income tax).

Post-SECURE 2.0 inherited IRA rules (2026): Non-spouse beneficiaries who inherit a traditional IRA from someone who died after 2020 must distribute the full account within 10 years. If the decedent was past their Required Beginning Date (age 73 for those born 1951–1959; age 75 for those born 1960+), annual RMDs are also required within that 10-year window per T.D. 10001 finalized July 2024.⁵ Inheriting a $1M IRA in this environment means a decade of ordinary income — at rates up to 37% — on top of whatever the beneficiary earns. Spouses retain the option to roll inherited IRAs into their own IRAs and defer under standard RMD rules.

Beneficiary designations override your will. If your IRA beneficiary designation names your estate, the account goes through probate and loses the stretch options for individual beneficiaries. Review designations annually — especially after a business sale creates new accounts or changes in income levels shift Roth conversion opportunities.

Roth accounts are better estate assets. Roth IRAs and Roth 401(k)s (which have no lifetime RMDs per SECURE 2.0 § 325) can grow tax-free and pass to heirs who withdraw tax-free. The 10-year rule still applies to inherited Roth accounts, but without the income tax burden. If a business exit creates a low-tax window (the year after a sale when ordinary income is lower), it's also a Roth conversion window — see Roth Conversion Strategy for Business Owners →

Business interests and step-up in basis

Unlike gifts (which carry over your cost basis to the recipient), inherited assets receive a stepped-up cost basis equal to fair market value at the date of death.² For a business owner who built a company from nothing — with a basis near zero — dying with the business in your estate means heirs inherit it at a $4M basis (if it's worth $4M at death) rather than $50K (your original investment). That eliminates the embedded capital gains tax entirely.

This creates a classic planning tension:

• If you give business interests to heirs during your lifetime, you transfer your low basis. A future sale triggers capital gains on the full appreciation.
• If you hold the business until death, heirs get a stepped-up basis and can sell with minimal or no capital gains — but the asset is in your taxable estate.

The math depends on your estate's size relative to the $15M exemption. If your estate is well below $15M, there's no estate tax — so the step-up strategy is superior. If your estate is above $15M, the 40% estate tax exceeds the 23.8% capital gains rate, making earlier lifetime transfers more attractive. Most business owners with estates under $15M are better served by the step-up strategy for the core business interest, while using annual gifts and GRATs to move out future appreciation on a tax-efficient basis.

Essential estate planning documents for business owners

A complete estate plan for a business owner includes:

1. Revocable living trust + pour-over will. The trust holds business interests and other major assets, avoiding probate. The pour-over will captures anything not retitled into the trust before death. Probate can freeze business assets for months — a living trust avoids this.
2. Business succession provisions. The trust (or a separate shareholder agreement or buy-sell agreement) must specify who controls the business interest after death, what happens to voting rights, and whether the executor can operate, sell, or wind down the business. Ambiguity here is catastrophic.
3. Durable power of attorney. Designates someone to make financial decisions — including operating or selling the business — if you're incapacitated but not deceased. This is separate from the trust and often more immediately relevant.
4. Healthcare proxy / advance directive. Designates someone to make medical decisions and documents your wishes. Required in every state; not specific to business owners, but owners often neglect this while focused on business documents.
5. Buy-sell agreement coordination. The buy-sell agreement governs business transfer among co-owners at triggering events (death, disability, divorce, departure). The estate plan must not contradict the buy-sell. Both must use consistent valuation methods. See Buy-Sell Agreement Guide →
6. Life insurance beneficiary review. Personal life insurance should be owned by an ILIT (not you or your estate) and have clean beneficiary designations. Business-owned key-person insurance has separate considerations. See Key-Person Insurance Guide →
7. Updated beneficiary designations. IRA, 401(k), SEP, and life insurance beneficiary forms. These override the will. Review every 3–5 years and after major life events (sale of business, divorce, new grandchildren).

When to update your estate plan

Your estate plan should be reviewed when:

• Business value changes significantly (up or down by 50%+)
• You add a co-owner or lose one
• You're within 5 years of a planned exit
• You sign or amend a buy-sell agreement
• A family member is added (marriage, children, grandchildren) or removed (divorce, death)
• You move to a different state (state estate tax rules vary widely)
• Tax law changes meaningfully (the OBBBA was one such moment)

A rule of thumb for active business owners: review the estate plan every 3 years and in the 12–18 months before any anticipated liquidity event.
