QSBS Gift to Trust, What Founders Need to Know

Each properly structured non-grantor trust you fund with QSBS gets its own Section 1202 exclusion cap. Here is what that requires and where founders lose it before closing.

This article addresses completed-gift, domestic non-grantor trusts. Gifting QSBS to a properly structured non-grantor trust preserves the Section 1202 exclusion (the federal tax break on QSBS gains) and gives that trust its own limit, independent of the founder’s personal limit. That matters because Section 1202 limits the eligible gain that each taxpayer can take into account from a particular issuer. Before reductions for prior eligible gain, the dollar limit is $10 million for stock acquired on or before July 4, 2025, and $15 million for stock acquired after that date, with the latter indexed for inflation beginning in 2027. A separate 10-times-basis alternative can produce a higher limit. The amount actually excluded also depends on the applicable exclusion percentage. Because founder shares typically carry near-zero basis, the flat dollar limit is usually the binding one.

Gain above the applicable limit is not excluded under Section 1202, even when a trust structure could have sheltered more. A trust gift made at the right time and structured correctly can multiply the total excluded gain, turning a significant tax bill into a fraction of what it would have been.

Section 1202(h) explicitly permits QSBS to be transferred by gift without stripping the stock of its qualified status. The recipient inherits the donor’s holding period, so the clock does not restart after the gift. The trust also generally takes a carryover basis, subject to applicable statutory adjustments, meaning most gifted founder shares, which carry a near-zero basis, rely on the flat-dollar limit rather than the 10x-basis alternative.

Not every trust creates a second exclusion limit. One of the determining factors is whether the trust is a separate taxpayer from the founder. Grantor trusts are not, which means the founder’s limit is the only one in play regardless of how the stock is titled.

Revenue Ruling 85-13 treats a grantor trust as disregarded for income tax purposes to the extent the trust is treated as owned by the relevant person; grantor trust treatment can apply to only part of a trust. Transferring QSBS to a grantor trust creates no second exclusion limit. The trust must avoid grantor trust status under Sections 671 through 679; retained powers that trigger those rules collapse the trust back into the founder for income tax purposes.

Trustee selection is important, but appointing an independent trustee does not by itself establish non-grantor status. Counsel must review the trust’s powers, beneficial interests, fiduciaries, and administration under Sections 671 through 679. A conventional SLAT, for example, is commonly a grantor trust because income can benefit the grantor’s spouse under Section 677. To the extent the founder is treated as the owner of the QSBS for federal income tax purposes, the trust does not create an additional exclusion for that stock. As a planning matter, the founder should not serve as trustee.

The limit each trust can claim depends on when the underlying stock was acquired, not when the gift occurs. Pre- and post-OBBBA shares carry different limits, and those limits travel with the stock. For gifted stock, the trust takes the donor’s original acquisition date, so a post-2025 gift of pre-OBBBA stock stays under the $10M regime.

For stock acquired after July 4, 2025, the OBBBA (signed July 4, 2025) applies a tiered exclusion system:

The final column is arithmetic using the applicable exclusion percentage and top tax rates. It assumes the taxable portion is subject to those rates, NIIT applies, and there are no offsets. It excludes state taxes and gain above the applicable Section 1202 limit. Stock held one year or less generally produces short-term gain taxed at ordinary rates, with NIIT potentially applicable.

An important clarification: using the unindexed $15 million dollar limit, the three-year tier can exclude $7.5 million, and the four-year tier can exclude $11.25 million. The $15 million amount is not itself the amount excluded at those holding periods. These tiers are also forward-looking for current planning: stock first acquired after July 4, 2025 cannot reach a three-year holding period until July 2028.

Pre-OBBBA stock (acquired on or before July 4, 2025) requires a holding period of more than five years for any exclusion. Exactly five years produces nothing; the tiers do not apply.

Gifted pre-OBBBA shares carry the $10M limit into the recipient’s hands regardless of when the gift occurs. Assume the founder and three qualifying non-grantor trusts each realize at least $10 million of eligible gain, have no prior eligible gain reducing their dollar limits, and hold shares acquired from September 28, 2010 through July 4, 2025 for more than five years. If the trusts are respected as separate taxpayers for the claimed exclusions, the four holders could exclude $40 million in aggregate. (Pre-OBBBA stock acquired before September 28, 2010 carries a 50% or 75% exclusion percentage, subject to special rules; holding it longer does not convert those percentages to 100%.) For post-OBBBA stock with a full five-year hold, four qualifying holders each reaching the unindexed $15 million limit could exclude $60 million in total as an illustration; that figure is not a fixed future ceiling, because inflation indexing begins before newly acquired post-OBBBA stock can satisfy a five-year holding period.

Multiple-trust planning requires an anti-abuse analysis. Section 643(f) provides for aggregation of certain trusts with substantially the same grantors and substantially the same primary beneficiaries when a principal purpose is tax avoidance. Spouses are treated as one person for this rule. Its application to a claimed multiplication of Section 1202 exclusions requires careful legal analysis: Section 643(f) expressly addresses treatment under Subchapter J, while Section 1202 sits in Subchapter P, and other doctrines (including assignment of income) can also reach aggressive structures.

Distinct beneficiaries and genuine non-tax purposes can be relevant, but different trustees, different trust names, or one trust per child do not create a statutory safe harbor. Risk factors include near-identical trusts created at the same time with overlapping beneficiaries and no independent estate planning purpose.

Structures designed with these risks in mind typically follow these principles:

• One trust per distinct beneficiary or beneficiary class (one per child is the cleanest pattern)
• Different trustees or institutional trustees across trusts
• Different distribution standards and documented non-tax purposes, such as asset protection or management for minors

In May 2026, Treasury’s assistant secretary for tax policy publicly signaled that guidance addressing QSBS stacking is forthcoming; reported remarks indicated particular concern about arrangements that go beyond one trust per family member, such as additional trusts for overlapping beneficiary combinations. Reported policy remarks should not be treated as an enacted limitation or a safe harbor. Counsel should confirm the guidance applicable when the structure is implemented and when the stock is sold.

A defensible multi-trust structure is as much an operational discipline as a legal one. Each trust should have its own EIN, separately maintained books and records, and its own Form 1041 filings when required, with distinct dispositive purposes documented in the trust instrument itself. Economic identity across trusts invites Section 643(f) aggregation risk even when the formal terms differ.

The same discipline applies to the QSBS position itself, which depends on original issuance, the holding period, the issuer’s qualifying business activities, and the gross-assets test measured over the relevant period before issuance and immediately after issuance, not simply a current balance sheet. Ju v. United States, No. 22-1815T (Fed. Cl. Mar. 18, 2024), illustrates the point: the court rejected the claim for some shares on original-issuance and holding-period grounds but left other shares unresolved because material factual disputes remained about issuance timing and the issuer’s qualifying status. Founders and trustees should preserve contemporaneous issuance records and evidence supporting the applicable gross-assets test, and confirm the trustee holds copies. The exclusion is only as strong as the records behind it.

The assignment of income doctrine gives the IRS authority to tax gain to the person who earned it, regardless of who technically holds the stock at closing. Transfers completed after a deal is practically certain arrive too late. The Tax Court’s ruling in Estate of Hoensheid v. Commissioner (T.C. Memo. 2023-34) made the standard clear: a charitable gift two days before closing was too late. The analysis turns on facts and circumstances, not a fixed safe harbor.

Begin planning while a sale remains genuinely uncertain. There is no fixed number of months that guarantees protection from the assignment-of-income doctrine. Counsel should evaluate the transaction’s actual progress and remaining contingencies before the gift is completed. An unsigned purchase agreement does not, by itself, establish that a gift is timely. Funding trusts when the company’s valuation is still low serves a second purpose: lower-valued shares consume less of the lifetime gift and estate tax exclusion per dollar of future exclusion captured.

For the non-grantor trusts discussed here, funding generally creates a taxable gift after any applicable exclusions and deductions. The gift uses the donor’s remaining federal gift and estate tax exclusion to the extent available; amounts exceeding the available exclusion may generate gift tax. In 2026, the basic exclusion amount is $15 million per individual; a married couple has two individual exclusions totaling $30 million, not an automatic $30 million allowance available to either spouse. Prior taxable gifts reduce what remains. There is no scheduled sunset under current law.

Obtain appropriate valuation support as of the gift date and report reportable gifts on a timely filed Form 709 with adequate disclosure. For a substantial gift of private-company stock, a qualified appraisal is often advisable, although the adequate-disclosure rules also permit specified detailed valuation information. Proper disclosure generally starts the applicable gift-tax assessment period. Expiration of that period does not validate the separate Section 1202 income-tax position.

Federal conformity to Section 1202 varies significantly by state. Trust situs alone does not determine state taxation; analyze the applicable state’s residency, sourcing, beneficiary, and distribution rules. Where the trustee sits and where the beneficiaries reside can pull the gain back into a high-tax state even when the trust is formed elsewhere. The table below covers selected jurisdictions, not a complete conformity survey.

California does not exclude the gain merely because Section 1202 excludes it federally. Under California Revenue and Tax Code Section 17742, the state taxes trust income based on the residency of fiduciaries and non-contingent beneficiaries, and California-source income can be taxable regardless of those parties’ residency. Mixed resident and nonresident fiduciaries or beneficiaries can require allocation rather than automatic taxation of every dollar. A Nevada-sited trust with a California trustee or a California-resident non-contingent beneficiary can still face California tax. Siting, trustee selection, and beneficiary design require coordination in any California-connected structure.
