QSBS Planning for UHNW Founders: Section 1202 After OBBBA

Not tax or legal advice. Verify all figures and strategies with qualified tax counsel before acting.

The One Big Beautiful Bill Act (OBBBA, July 2025) transformed Section 1202 qualified small business stock from a useful tax break into one of the most powerful wealth-building tools available to founders and early investors. For a UHNW founder with a $50M–$200M exit, getting QSBS right — or wrong — is worth tens of millions of dollars in federal tax.¹

This guide focuses on what changes at the $30M+ wealth level: advanced planning strategies most founders miss, the California problem that surprises even sophisticated investors, and how QSBS fits into a coordinated UHNW exit plan.

OBBBA changes to Section 1202

Before OBBBA, Section 1202 required a 5-year holding period to receive a 100% federal gain exclusion, capped at the greater of $10 million or 10× the taxpayer's adjusted basis. OBBBA, signed July 4, 2025, made three significant changes for stock issued after that date:²

The tiered holding-period structure is particularly important for UHNW investors: a founder who exits at year 3 or year 4 now gets meaningful federal exclusion rather than nothing. The 50% and 75% partial exclusions existed before OBBBA but required a hold of exactly 3 or 4 years as transition periods toward the 5-year threshold — OBBBA made the tiers permanent and standalone entitlements.

Pre-OBBBA vs. post-OBBBA stock: which rules apply

The OBBBA changes apply to stock newly issued after July 4, 2025. The effective date has specific implications:

• Stock issued ≤ July 4, 2025: The old $10M cap and $50M gross assets test apply permanently to that stock, regardless of when you sell. OBBBA cannot retroactively increase your exclusion cap on stock you already hold.
• Stock issued after July 4, 2025: $15M cap (inflation-indexed), $75M gross assets test at issuance, tiered holding periods at 3/4/5 years.
• Section 351 or Section 368 exchange of old stock into new stock: If you contributed pre-OBBBA QSBS to a new entity in a tax-free exchange, the new stock generally carries the $10M old cap — not the upgraded $15M limit. This is a specific trap for founders doing entity restructurings.
• Gifts of QSBS: A gift of QSBS transfers the donee into the donor's holding period and exclusion rules. The donee's exclusion cap is derived from the original issuance rules, not the date of the gift.

Qualification requirements

Stock qualifies under Section 1202 only if ALL of the following are met at issuance and maintained throughout the holding period:³

The corporation

• C-corporation status: The issuer must be a domestic C-corporation at time of issuance and throughout substantially all of the holding period. S-corporations, LLCs, and partnerships do not qualify. If you hold QSBS and the company converts to an S-corp, the §1202 clock typically stops.
• Gross assets test: The corporation's aggregate gross assets (cash + adjusted basis of other property) did not exceed $75M (post-OBBBA) or $50M (pre-OBBBA) immediately before and immediately after the issuance. Once the test is satisfied at issuance, later growth above the threshold does not disqualify previously issued stock.
• Active business requirement: During substantially all of the holding period, the corporation must be engaged in a qualified active trade or business (see ineligible businesses below).

The stockholder

• Original issue: You must have acquired the stock at original issue from the corporation — not in a secondary transaction, not from another stockholder. Secondary-market purchases of QSBS-eligible shares do not carry the §1202 benefit for the new buyer.
• Money, property, or services: The stock must have been acquired in exchange for money, property, or as compensation for services rendered. This covers founders receiving stock, employees receiving equity compensation, and investors making capital contributions.
• Individual or pass-through taxpayer: §1202 applies to individuals and most pass-through entities (S-corps, partnerships, LLCs). C-corporations cannot use the exclusion — which is why venture funds structured as LPs can flow the benefit through to their LP investors, but a C-corp holding QSBS cannot.

The real math: $50M+ QSBS gain

Consider a founder who receives 2,000,000 shares in a Series A round for $0.10/share ($200,000 total basis) in a software company qualifying as QSBS. The company exits 5 years later at $25/share. Her gain: $49.8M. Federal tax consequence:⁴

The difference between the "do nothing" scenario and a fully coordinated QSBS plan is over $10M in federal tax savings — on top of avoiding the 23.8% federal rate on the excluded gain. With two children each receiving gifted shares worth up to $15M at exit, and a DAF absorbing any remaining gain, a founder can exit a $50M position with negligible federal tax. The strategies that make this possible are explained below.

7 advanced UHNW planning strategies

1. Gift QSBS to family members before exit — each donee gets their own $15M cap

The §1202 exclusion cap is per taxpayer, per issuer. When you gift QSBS to another person, that donee holds the stock with your original acquisition date (for the 5-year clock) but benefits from their own separate $15M exclusion limit against gain recognized in their hands.

For a founder with a $100M exit, gifting shares to a spouse, children, and dynasty trusts for grandchildren can multiply the $15M cap across multiple taxpayers. A family of 5 with each member holding $15M of QSBS covers $75M in gain federally tax-free.

Timing matters: Gift the shares when their value is low — before significant appreciation, before the IPO, before the acquisition announcement. The gift tax consequences are determined by the value at the time of gift. Waiting until exit to "gift" appreciated shares creates a larger taxable gift and potentially gift tax. The strategic window is early: the Series A or B round when shares are still cheap.

Trust considerations: QSBS can be held in a grantor trust (such as an IDGT) and the §1202 exclusion flows through to the grantor/taxpayer. Non-grantor trusts are generally separate taxpayers each entitled to their own $15M cap, which creates stacking opportunities — but also requires careful structuring to avoid attribution issues. Confirm the trust structure with qualified counsel.

2. Stack exclusions across multiple QSBS issuers

The $15M cap is per issuer. A UHNW investor with QSBS in five different portfolio companies each has a $15M exclusion cap per company — potentially $75M+ in total federally excluded gain. This is the investor equivalent of stacking rather than the gifting approach above.

Angel investors and early-stage VCs with diversified QSBS portfolios can aggregate significant federal tax-free income over time. The key planning consideration is ensuring each investment independently meets all §1202 requirements, since the IRS scrutinizes the "active business" and "original issue" conditions carefully.

3. Section 1045 rollover: defer gain into new QSBS

If you sell QSBS before you've held it long enough to qualify for the minimum 3-year holding period for the 50% exclusion (or for any reason want to defer the gain), §1045 allows you to roll the proceeds into new QSBS within 60 days. The rolled gain is deferred until you sell the new QSBS, and your holding period on the original stock carries forward to the new stock.⁵

For UHNW founders with a forced liquidity event before 3 years, §1045 can preserve the QSBS tax benefit while redeploying capital into a new qualifying investment. The 60-day clock is strict — missing the window permanently forfeits the rollover opportunity.

4. California does not conform — time your domicile change

California is the most significant state non-conformity problem for QSBS planning. California does not conform to IRC §1202 — which means California taxes 100% of the QSBS gain at 13.3% regardless of how long you held the stock or whether you qualify for the federal exclusion.

A founder with a $50M QSBS exit who lives in California on the sale date owes approximately $6.65M in California state income tax even after getting the full federal exclusion. Moving from California before the exit — and satisfying the Franchise Tax Board's domicile standards — eliminates this liability entirely. See our domicile change guide for the FTB audit standards, the 9-month presumption, and the equity apportionment trap for unvested shares.

Other notable non-conforming states include New Jersey and Pennsylvania. If you live in one of these states, the state-level capital gains tax applies in full to QSBS gain. Most other states either conform to §1202 or have no income tax.

5. DAF contribution of QSBS: avoid gain entirely on the donated shares

Contributing appreciated QSBS to a donor-advised fund before an exit eliminates capital gains tax on the contributed shares entirely (the DAF is a tax-exempt entity that pays no tax on sale) and generates a charitable deduction based on fair market value at the time of contribution, limited to 30% of AGI for appreciated non-cash assets in a year (with 5-year carryforward).⁶

For a founder with $50M in QSBS, contributing the shares above the $15M exclusion cap into a DAF before the sale means the federally taxable gain above $15M disappears entirely — the DAF sells and retains the cash for charitable grant-making. Combined with the §1202 exclusion on the first $15M, a founder can exit a $50M QSBS position with $0 federal tax and a large charitable deduction for future giving. This is the same strategy outlined in our philanthropic vehicles guide and our post-exit planning guide.

Note: California's non-conformity problem still applies to the donated shares unless domicile has been changed before the exit. Confirm California timing with your CPA.

6. QSBS before IPO: maximize exclusion before appreciation

The most powerful QSBS planning is done years before exit. Once a company is on an IPO trajectory or has received a major acquisition offer, the share price is already high and the opportunities narrow. The strategies that generate the most value — gifting to family members at low valuations, contributing to DAF while shares are cheap, establishing IDGTs before the big appreciation — all work best when done early.

If you're a founder holding QSBS in a pre-Series C company, the questions to be asking now are: Have I confirmed this stock qualifies as QSBS? Is my basis documentation clean? Have I considered gifting some shares to trusts or family members while the 409A is still low? Is the company still below the $75M gross assets test threshold? Getting these answers while you have time is far more valuable than trying to plan retroactively in the 90 days before an IPO.

7. QSBS in an IDGT: supercharge estate and income tax planning

An Intentionally Defective Grantor Trust (IDGT) funded with QSBS at low pre-exit values creates a powerful combination: the §1202 exclusion flows through to the grantor (since the trust is a grantor trust for income tax), and the future appreciation occurs entirely outside the grantor's taxable estate. When the IDGT sells the QSBS at exit, the grantor's personal tax return claims the §1202 exclusion on the excluded gain.⁷

The gift of QSBS into the IDGT at current low value uses minimal gift tax exemption (compared to the exit value), removes the future appreciation from the estate, and still generates the full §1202 federal exclusion for the grantor. For a founder with a $100M exit who gifts QSBS into IDGTs for children when shares are at $1M total value, the gift uses $1M of exemption while removing $99M+ in future gain from the estate — and the §1202 exclusion covers the first $15M per taxpayer.

See our IDGT guide for the mechanics, note structure, and seed gift requirements.

The California trap in detail

California's non-conformity to §1202 is not theoretical — it's a $6–$13M tax bill on large exits that founders routinely overlook until it's too late. The mechanics:

• California taxes all capital gains as ordinary income at your marginal rate (up to 13.3% for income above ~$1M).
• California does not recognize the §1202 exclusion at all. The federally excluded gain is fully taxable in California.
• If you are a California resident at the time of the sale, California will tax the entire QSBS gain regardless of the federal exclusion.
• The Franchise Tax Board has long-arm audit authority for equity income from California-based companies. Even if you've moved, CA may argue apportionment if vesting or services were rendered in California while you were a CA resident.

The planning solution: Establish domicile in a state with no income tax (Florida, Texas, Nevada, South Dakota, Wyoming, Washington) before the sale. California's closest-connections standard requires a genuine change of domicile — not just buying a second home. See our detailed guide to domicile change for UHNW families for the FTB audit standards and the documentation checklist required to survive scrutiny.

Timing: For an anticipated IPO or acquisition, begin the domicile change process at least 12–18 months before the expected closing date. FTB will examine every element of your life — where your primary residence is, where your family and social ties are, where your business activities are — to determine whether the move was genuine.

Ineligible business types

Section 1202 explicitly excludes several business categories from qualifying as a "qualified active trade or business." If the company is primarily in one of these sectors, the stock does not qualify:³

• Professional services: Any business where the principal asset is the reputation or skill of specific employees — including health, law, engineering, architecture, accounting, actuarial science, performing arts, consulting, athletics, financial services, and brokerage services. Most SaaS companies, manufacturing companies, and technology hardware companies qualify. A consulting firm, law firm, or accounting firm does not.
• Hospitality: Hotel, motel, restaurant businesses are excluded.
• Financial and investment businesses: Banking, insurance, financing, leasing, or investing (holding or trading financial instruments). VC funds and PE funds themselves are not QSBS; their portfolio companies may be.
• Farming: Agricultural operations are excluded.
• Mining/oil/gas: Businesses producing petroleum and natural gas products.

The professional services exclusion catches some technology-adjacent companies by surprise. A healthcare IT company that also employs physicians for clinical services may not qualify. An architectural software company is fine; an architecture firm is not. When in doubt, get a legal opinion on QSBS qualification at the time of stock issuance — not at the time of exit.

Questions to ask your advisor about QSBS

At the UHNW level, QSBS planning is not a single advisor's domain — it requires coordination between your tax attorney, CPA, and financial planner. Key questions:

1. Does my stock qualify? Request a written QSBS qualification analysis covering: C-corp status at all times, gross assets test at issuance, active business qualification, and original-issue requirement. Get this before the exit, not after.
2. Pre-OBBBA or post-OBBBA? If your stock was issued before July 5, 2025, the $10M cap applies. Know which rules govern your specific shares.
3. How much of my total gain is covered by my personal $15M? For founders with larger positions, understand the amount above the $15M threshold and plan accordingly (gifting, DAF, domicile change).
4. Have we considered gifting shares to trusts or family members before the exit? This is the single highest-leverage QSBS planning strategy for UHNW founders — and it requires time. If the exit is imminent, the window may be nearly closed.
5. What is my state income tax exposure? California non-conformity is critical. If you're a CA resident, quantify the state tax cost and evaluate domicile change timing.
6. Is §1045 rollover relevant? If the exit is under 3 years from issuance, evaluate whether rolling into new QSBS makes sense.
7. How does QSBS interact with my overall estate plan? GRATs, IDGTs, and SLATs all interact with QSBS gifting strategies. The sequencing of which trust gets which shares, and when, should be coordinated across your estate planning attorney, CPA, and financial advisor.
