Selling a Business: Trust Ownership vs LLC vs Personal Holding — Tax Implications (2026)

The entity structure holding your business at the moment of sale determines whether you pay 23.8% federal capital gains tax, 30-50% combined federal-state tax, or potentially eliminate state tax entirely and reduce estate-tax exposure. The decisions made in the 2-5 years before a sale — entity conversions, trust formations, family gifting, basis adjustments — often have larger tax consequences than the deal terms themselves. A founder with a $20M business and three children, properly structured, can save $3-6M in combined income, state, and estate taxes. Improperly structured, the same founder pays $5-7M in unnecessary tax.

This guide compares the four most common ownership structures (personal, LLC, grantor trust, non-grantor trust), explains the basis step-up at death rules under §1014, walks through the GRAT and IDGT gifting mechanics, and discusses the timing requirements for pre-sale conversions. It also addresses the interaction with estate tax (federal and state), the 2026 sunset of the elevated lifetime exemption, and the asset-protection trade-offs of each structure.

We are CT Strategic Partners, a U.S. buy-side M&A firm based in Sheridan, Wyoming. We work with 76+ active capital partners across the lower middle market, and we routinely walk founder-sellers through pre-sale entity and estate-planning conversations when a likely exit is 12-36 months out. Our model is buyer-paid — sellers pay nothing, sign nothing, and walk away at any time. For trust formation and tax planning specifically, you’ll need to engage an estate-planning attorney and a CPA; we can refer you to specialists in our network who routinely handle pre-sale structures.

A note on the bar: trust structuring is highly fact-specific. The wrong trust type can lock up assets unnecessarily, trigger gift tax, or produce no estate-tax benefit. Rushing trust formation in the weeks before a sale invites IRS challenge under economic-substance and step-transaction doctrines. The TCJA exemption sunset (currently scheduled for 12/31/2025 with potential extension or modification) adds urgency for high-net-worth founders. Engage estate-planning counsel early — 2-5 years before a likely exit is the sweet spot.

Personal ownership vs single-member LLC: the baseline comparison

Personal ownership (sole proprietor or direct stock)

Simplest structure: the founder personally owns the business stock or sole proprietorship. Federal income tax flows to the individual at sale. Capital gain on the sale of stock or business assets receives long-term capital gain treatment if held more than one year (20% LTCG + 3.8% NIIT = 23.8% federal). State tax varies (0% in WY, NV, FL, TX, SD, WA, TN; 13.3% in CA at the high end). No estate-tax planning. Full estate inclusion at death. Basis step-up to FMV at death under §1014.

Single-member LLC

The LLC is disregarded for federal tax purposes — same as personal ownership above. Same tax consequences on sale. The advantage of LLC: liability protection from operating-business claims (the LLC veil shields personal assets), governance flexibility, and the ability to convert to multi-member LLC or partnership if family members are added. Limited estate-tax benefit unless interests are gifted before sale.

The basis step-up rule under §1014

If the founder holds the business at death, the heirs receive a basis step-up to FMV at the date of death (or alternate valuation date six months later). This wipes out all unrealized capital gain accumulated during the founder’s lifetime. For a founder who would otherwise sell during life, holding through death and giving heirs the stepped-up basis can eliminate capital-gain tax entirely — but only if the founder doesn’t need to monetize the asset during life.

The estate-tax conflict

The basis step-up benefit is offset by federal estate tax. For 2026, the federal estate-tax exemption is approximately $13.99M per individual ($27.98M for married couples). Above the exemption, federal estate tax is 40%. For a founder with a $30M business + $5M other assets, holding through death saves capital-gain tax but exposes ~$7M to estate tax (~$2.8M of estate tax). The math usually favors selling during life for very high-net-worth founders unless trust structuring reduces estate exposure.

Grantor trust vs non-grantor trust: the fundamental distinction

Trusts come in two flavors that have very different tax consequences:

Grantor trust

The trust is treated as ‘transparent’ for income-tax purposes — all income, deductions, and credits flow to the grantor (the person who established the trust). The grantor pays the income tax on trust earnings as if they personally earned it. This is generally beneficial for wealth transfer because:

• The grantor’s payment of trust taxes effectively gifts additional wealth to the trust beneficiaries (income tax payments are not treated as gifts)
• The grantor and trust can engage in tax-free transactions with each other (sales, loans, exchanges)
• The grantor can pay the trust’s income tax with non-trust assets, preserving the trust corpus for beneficiaries

Estate-tax consequence: grantor-trust status is set by triggering specific powers in the trust document. Most grantor trusts are NOT included in the grantor’s taxable estate if the trust is irrevocable and properly structured.

Non-grantor trust

The trust is a separate taxpayer with its own income tax. Trust income is taxed at compressed brackets (the top 37% rate applies above ~$15K of taxable income in 2026). Distributions to beneficiaries carry out income to the beneficiary’s lower rates. Beneficial when:

• The trust is intended to multiply state-tax savings (each non-grantor trust can be a separate QSBS holder)
• The grantor doesn’t want to pay the trust’s ongoing income tax
• The grantor needs the trust to be a separate taxpayer for specific tax-planning purposes

State-tax planning with non-grantor trusts

A non-grantor trust established in a tax-friendly state (Wyoming, South Dakota, Nevada, Florida, Texas, Tennessee) can be sourced to that state for trust income tax. The grantor in California can establish a Wyoming non-grantor trust, fund it with QSBS, and the trust’s capital gain on QSBS sale is sourced to Wyoming. California has aggressively contested this; the rules depend on trustee location, trust administration location, and beneficiary residency. Properly structured ‘NING’ trusts (Nevada Incomplete-gift Non-Grantor) and ‘DING’ trusts (Delaware) can save 10-13% in state tax on multimillion-dollar gains.

GRAT and IDGT: pre-sale gifting structures

Grantor Retained Annuity Trust (GRAT)

A GRAT is an irrevocable trust under IRC §2702 in which the grantor transfers appreciating assets to the trust in exchange for an annuity payment over a fixed term (typically 2-10 years). The annuity is calculated so that the present value of the annuity stream equals the value of the gift, leaving zero gift tax. Any appreciation in the trust assets above the §7520 interest rate passes to the trust beneficiaries gift-tax-free.

GRAT example

Founder transfers $5M of pre-IPO stock (expected to be worth $15M at GRAT termination) to a 2-year GRAT. §7520 rate is 4.8%. Annual annuity = ~$2.69M. After 2 years, $5.38M of annuity is returned to the grantor (essentially the original principal plus interest). Remaining $9.62M+ stays in the trust for the beneficiaries — gift-tax-free.

Best uses of GRATs

GRATs work best with assets expected to appreciate substantially in a short time period: pre-IPO stock, pre-sale private business interests, or assets with high illiquidity discounts. The trust beneficiaries are typically the grantor’s children or grandchildren. Mortality risk: if the grantor dies during the GRAT term, the trust assets are included in the estate, undoing the structure.

Intentionally Defective Grantor Trust (IDGT)

An IDGT is an irrevocable trust that is ‘defective’ for income-tax purposes (the grantor remains taxable on trust income) but effective for estate-tax purposes (the trust assets are outside the grantor’s taxable estate). The ‘defectiveness’ is achieved by including specific grantor-trust triggers (typically the power to substitute trust property of equivalent value).

IDGT installment sale strategy

The most powerful IDGT play: the grantor ‘sells’ appreciating assets to the IDGT in exchange for an installment note at the AFR rate. The IDGT pays interest to the grantor at the (low) AFR rate, and the trust assets appreciate above the AFR. The appreciation passes to beneficiaries gift-tax-free. Because the IDGT is a grantor trust, the sale is not recognized for income tax purposes — no capital gain on the transfer. This is one of the most powerful estate-tax-reduction techniques available to high-net-worth founders.

Pre-sale GRAT/IDGT timing

Best practice: fund the GRAT or IDGT 2-5 years before the anticipated business sale. Why: (a) economic-substance and step-transaction risk if formed too close to sale, (b) needs time for appreciation to occur inside the trust, (c) IRS adequate-disclosure requirements for valuations. Funding within 6-12 months of sale invites IRS challenge on valuations.

The TCJA sunset and 2026 planning urgency

The Tax Cuts and Jobs Act of 2017 (TCJA) raised the federal estate and gift tax exemption to roughly twice the prior level. For 2026, the exemption is approximately $13.99M per individual. This elevated exemption is scheduled to sunset on December 31, 2025 (technically already sunset under current law, with planned reverting to ~$7M per individual indexed for inflation, unless Congress extends it). The exact sunset behavior depends on legislation enacted (or not enacted) by year-end 2025.

The lifetime gift opportunity

For founders with $14M+ in assets, the 2026 window is critical: lifetime gifts that use the elevated exemption are permanently excluded from the donor’s estate, even if the exemption later sunsets. This is sometimes called the ‘use it or lose it’ opportunity. A married couple can shift up to $27.98M outside the estate before the sunset.

Anti-clawback rules

The IRS has confirmed (through Treasury Regulations §20.2010-1) that lifetime gifts made using the elevated exemption will NOT be ‘clawed back’ if the exemption later sunsets. This means high-net-worth founders should consider front-loading lifetime gifts before any sunset event.

Implementation for a planned business sale

The typical sequence: (1) form irrevocable trusts (IDGT or non-grantor) in tax-friendly states 2-5 years before sale, (2) gift business interests to the trusts using the elevated exemption while still available, (3) allow the gifted interests to appreciate inside the trusts toward the eventual sale, (4) sell the business at the planned exit, with trust-held portions taxed at trust-level rates and excluded from the grantor’s estate. This shifts substantial wealth outside the estate while still preserving the grantor’s income from the personally-held portion.

Federal vs state estate tax

Even if the federal exemption stays at $14M, several states impose their own estate or inheritance tax at much lower thresholds: Massachusetts ($2M), Oregon ($1M), New York ($6.94M), Washington ($2.19M), Connecticut ($13.61M), Hawaii ($5.49M), Minnesota ($3M), Illinois ($4M), Rhode Island ($1.77M), Maine ($6.8M), Maryland ($5M), Vermont ($5M), DC ($4.71M). Founders in these states face state-level estate tax exposure that pre-sale gifting can mitigate.

Putting it together: the pre-sale structural decision tree

Step 1: Quantify expected proceeds and gain

Estimate the expected sale price, current basis, and resulting gain. Calculate federal and state tax at three scenarios: all-personal, all-LLC, and trust-shifted (50%). The difference between scenarios drives the planning effort.

Step 2: Assess estate-tax exposure

If total estate (post-sale) is below the federal exemption ($14M+ for individuals, $28M+ for married), estate-tax planning is less critical and the focus shifts to state-income-tax planning. If above the exemption, aggressive lifetime gifting is the primary lever.

Step 3: Identify state-tax savings opportunities

For sellers in high-tax states (CA, NY, NJ, MA, OR, MN), evaluate non-grantor trust structures sourced to tax-friendly states. The state-tax savings on a $10M gain at California’s 13.3% rate is $1.33M — well worth the $50-150K of trust setup costs.

Step 4: Determine charitable intent

If charitable intent exists, consider charitable remainder trusts (CRT) or donor-advised funds (DAF) as part of the pre-sale structure. A CRT can eliminate capital gains on contributed shares and provide lifetime income.

Step 5: Plan basis-step-up vs sale-during-life

For very high-net-worth founders who don’t need full sale proceeds during life, retaining interests until death captures the §1014 basis step-up. This is most useful for founders with substantial other liquidity who can afford to keep the business interest illiquid.

Step 6: Execute 2-5 years before sale

Trust formations, gifting, entity conversions, and §83(b) elections all have lookback periods or require time to satisfy substance requirements. The further from the sale event the planning is done, the cleaner the tax treatment and the lower the audit risk.

Frequently Asked Questions

Should I put my business in a trust before selling?

It depends on your estate-tax exposure and state-tax situation. For founders with $14M+ total estate, lifetime gifting via IDGT or non-grantor trust can save substantial estate tax and (in tax-friendly trust states) state income tax. For founders below the exemption, personal or LLC ownership with basis-step-up planning is usually simpler. Always engage estate-planning counsel 2-5 years before a likely sale.

What’s the difference between grantor and non-grantor trusts?

Grantor trusts are transparent for income tax — the grantor pays the trust’s income tax personally, which effectively gifts additional wealth to beneficiaries. Non-grantor trusts are separate taxpayers, taxed at compressed brackets. Grantor trusts are generally better for income-tax management; non-grantor trusts can be sourced to tax-friendly states for state-tax savings.

What is a GRAT?

A Grantor Retained Annuity Trust is an irrevocable trust in which the grantor transfers assets in exchange for an annuity over a fixed term. The annuity returns the principal plus interest to the grantor; any appreciation passes to beneficiaries gift-tax-free. GRATs are most useful for assets expected to appreciate quickly (pre-sale business interests, pre-IPO stock).

What is an IDGT?

An Intentionally Defective Grantor Trust is irrevocable for estate-tax purposes (assets outside the taxable estate) but transparent for income-tax purposes (grantor remains taxable). The combination allows tax-free transactions between grantor and trust, including installment sales of appreciating assets at the AFR rate. One of the most powerful estate-reduction techniques available.

How long before a sale should I form a trust?

Best practice is 2-5 years. Earlier formations have cleaner economic substance and avoid step-transaction challenges. Trust formations in the 6-12 months before a sale invite IRS scrutiny on valuations. Some structures (CRTs) can be formed within a year of sale if proper documentation exists, but most multi-generational planning should be done years in advance.

Will the federal estate tax exemption sunset?

Under current law, the elevated TCJA exemption is scheduled to sunset after December 31, 2025, reverting to approximately $7M per individual (indexed). Whether Congress extends or modifies the exemption is uncertain. The IRS has confirmed lifetime gifts made under the elevated exemption will not be clawed back, creating a ‘use it or lose it’ opportunity for 2025.

Can my LLC qualify for QSBS?

No. LLCs are not C-corporations and don’t qualify for QSBS Section 1202 treatment. Conversion to C-corp is required to start the QSBS clock. Conversion 5+ years before sale captures the full $10M exclusion; conversion under 5 years before sale captures nothing.

Do trusts get a basis step-up at the grantor’s death?

Depends on the trust type. Assets in a revocable (living) trust receive a step-up at the grantor’s death because the assets are included in the grantor’s estate. Assets in an irrevocable trust (IDGT, GRAT, dynasty trust) generally do NOT receive a step-up because they’re outside the estate. This is the main trade-off in pre-sale gifting: save estate tax, lose basis step-up.

Which states have estate or inheritance tax?

States with their own estate or inheritance tax include MA, OR, NY, WA, CT, HI, MN, IL, RI, ME, MD, VT, DC, PA, NJ, KY, NE, IA. Thresholds and rates vary widely. Founders in these states face state-level estate tax exposure even if below the federal exemption, making pre-sale gifting particularly valuable.
