Short answer
What this page answers
Qualified small business stock (QSBS) under Section 1202 may let eligible founders, employees, and investors exclude qualifying gain from federal tax, under rules that changed for stock acquired after July 4, 2025. Pre-exit planning reviews eligibility facts, documentation, estate and state coordination, and advisor sequencing before a letter of intent compresses the timeline.
Who this is for
- Founders of C corporations approaching a financing or exit
- Early employees with exercised options, restricted stock, or 83(b) elections
- Angel and venture investors holding original-issuance stock
- Families and trustees holding founder stock in trusts
- Companies that converted from LLC or S corporation status
- Advisor teams needing one coordinated pre-exit record
Why timing before the LOI matters
Entity history, issuance documents, and gross-asset support are fixed facts by the time a buyer appears. What stays flexible is how well those facts are proven and how ownership is arranged, and that flexibility narrows sharply once a letter of intent or exclusivity exists: transfers made after a gain has effectively ripened can be recharacterized to the original holder under assignment-of-income principles.
Before the LOI, records can still be gathered, counsel can structure transfers with years behind them, and rollover and charitable questions can be weighed rather than rushed.
QSBS and Section 1202 review areas
Stock qualifies only if every condition is met, and most are fixed at issuance:
- Eligible issuer. A domestic C corporation must issue the stock; S corporations and LLCs taxed as partnerships cannot.
- Original issuance. The stock must come directly from the company for money, property other than stock, or services; stock bought from another shareholder does not qualify.
- Gross-asset test. Aggregate gross assets must stay within the ceiling through issuance: $50 million under the legacy rules, $75 million for stock issued after July 4, 2025.
- Active business. At least 80% of assets by value must be used in a qualified trade or business during substantially all of the holding period; fields such as health, law, consulting, and financial services are excluded.
- Holding period. More than five years for legacy stock’s full exclusion; a tiered three, four, and five-year schedule for stock acquired after July 4, 2025.
Grant-side timing feeds these gates: an 83(b) election filed within its 30-day window starts the holding period at grant or early exercise, and option stock starts its clock at exercise. The engagement is described on the QSBS and Section 1202 planning service page.
Two QSBS rule sets after the 2025 law change
The 2025 legislation expanded Section 1202 for newly acquired stock and left earlier stock on the prior framework, so blocks are tracked under two regimes:
| Feature | Stock acquired on or before July 4, 2025 | Stock acquired after July 4, 2025 |
|---|---|---|
| Exclusion schedule | 100% after a more-than-five-year hold (most stock acquired after September 27, 2010) | Tiered: 50% after more than three years, 75% after more than four, 100% after more than five |
| Per-issuer cap | Greater of $10 million or 10 times adjusted basis | Greater of $15 million (indexed after 2026) or 10 times adjusted basis |
| Gross-asset ceiling | $50 million at issuance | $75 million (indexed), for stock issued after July 4, 2025 |
Blocks keep their original acquisition date: a rollover or reorganization that carries over the holding period also carries the old acquisition date, so pre-2025 stock stays under the earlier framework.
Estate and trust coordination
Stock transferred by gift or at death generally keeps its QSBS character, and the recipient tacks the transferor’s holding period, so a completed gift does not restart the clock. Because the cap applies per taxpayer, per issuer, families sometimes review with estate counsel whether properly structured non-grantor trusts, each a genuine separate taxpayer with distinct beneficiaries, can each apply their own cap.
The conservative framing matters. A grantor trust adds no separate cap, near-identical trusts for the same beneficiary invite consolidation and step-transaction challenges, and transfers after a sale is in view face assignment-of-income scrutiny. What holds up: completed gifts made years early, real beneficiaries, independent trustees, and gift tax returns with qualified appraisals. Holding a block until death, with its basis step-up, is the alternative worth weighing.
State and residency considerations
Section 1202 is a federal exclusion, and state conformity is not automatic. California does not conform and taxes the gain in full; other states conform partially or with their own limits. Residency, domicile timing, trust situs, and sourcing shape the state result, and residency changes close to a sale receive close examination.
Documentation and eligibility gaps
Most QSBS positions are won or lost on records. Worth reviewing before any sale process:
- Incorporation documents, entity history, and continuous C corporation status support
- Stock ledger, cap table history, and subscription or purchase agreements
- Option exercise records and 83(b) elections with proof of timely filing
- Gross-asset workpapers dated at each issuance
- Active-business support and excluded-field screening
- Redemption, repurchase, and tender history around issuance windows
- Conversion records for companies that began as LLCs or S corporations
- Gift, trust, charitable, and transfer records with holding-period schedules
- Basis records and acquisition dates for every block, since the date determines the rule set
Section 1045 rollovers
A sale before the holding period matures is not automatically a lost exclusion. A holder who has held QSBS more than six months may defer gain by reinvesting proceeds in replacement QSBS within 60 days, with the original holding period carrying over. The replacement must independently qualify, partial reinvestment triggers partial recognition, and the rolled block keeps its original acquisition date. Sixty days pass quickly; this is a before-the-sale conversation.
Common failure modes worth screening early
- The S corporation detour. Stock affected by a mid-history S election may not qualify; the problem often surfaces first in buyer diligence.
- The late LLC conversion. The holding period starts at conversion, and pre-conversion appreciation does not qualify.
- Redemptions near an issuance. Buybacks and tenders within defined windows can taint stock issued in the window; screening belongs before the buyback.
- Secondary purchases. Stock bought from another shareholder is never original-issuance stock, even when the company qualifies.
- Eve-of-sale transfers. Gifts and trust funding after a deal is in view face assignment-of-income scrutiny.
- Records that surface too late. Diligence teams ask for issuance and gross-asset support that may be a decade old.
How MMVFO coordinates advisors before the LOI
Pre-exit planning fails most often between advisors: the CPA sees the returns, corporate counsel sees the cap table, estate counsel sees the trusts, and no one owns the combined record. MMVFO builds that record and sequences the review, while regulated implementation remains with properly licensed or registered professionals.
- Map the facts: entities, stock blocks, acquisition dates, basis, and prior transfers in one working view.
- Close documentation gaps while the company and its counsel can still produce the records.
- Sequence counsel-led estate, trust, charitable, state, and rollover review in the right order, with time to act.
- Organize diligence responses, valuation support, and reporting positions before exclusivity compresses the calendar.
The engagements are described on the founder pre-exit tax planning and transaction tax readiness pages; for families whose exit is one part of a larger picture, the same discipline extends to the tax-led virtual family office model.
Pre-exit diagnostic checklist
- Confirm entity history and the acquisition date for every block of stock.
- Map caps, holding periods, and rule sets block by block, including trust-held shares.
- Identify documentation gaps while they can still be closed.
- Review estate, trust, gifting, and state questions with counsel before any sale discussion.
- Set the advisor sequence so tax, legal, and valuation review happen before the LOI.
