Section 1202 can exclude up to $10M of gain on a founder's exit, but only if the stock was originally issued in a qualifying structure and held for five years. We walk through the common traps we see at formation.
Section 1202 of the Internal Revenue Code permits a non-corporate shareholder to exclude from federal income tax up to the greater of $10 million or ten times basis in gain recognized on the sale of qualified small business stock (QSBS) held for more than five years. For a founder whose equity is worth meaningful money at exit, the difference between qualifying and not qualifying is often the largest single line on their personal tax return, and the rules are unforgiving of formation-stage missteps.
The most basic requirement — that the stock be issued by a domestic C corporation — is also the most commonly overlooked. Founders who form an LLC at inception and later convert to a C corporation start the five-year holding period on the conversion date, and the qualified-small-business gross-asset test is applied at that date. We regularly see clients who could have preserved a full QSBS position by forming as a C corporation at the outset and who lost the benefit on a post-hoc conversion because the conversion valuation pushed the gross-asset figure above the $50 million ceiling.
The $50 million gross-asset cap is measured immediately after issuance and includes cash raised in the same round. A seed-stage company that raises a $12 million priced round is generally still well within the ceiling, but a Series B at a $60 million pre-money valuation — even if the company itself has minimal operating assets — will typically blow the cap and render any stock issued in or after that round non-qualifying. Stock issued before the company crossed the threshold, however, remains eligible. We advise founders to document the gross-asset picture at each issuance as a contemporaneous matter so that, a decade later, there is no dispute about which tranche qualifies.
The active business requirement demands that at least 80% of the corporation's assets be used in the active conduct of a qualified trade or business during substantially all of the holding period. Service businesses — law, health, engineering, consulting, financial services, and most other personal-services trades — are categorically excluded. The borderline cases are software and technology-enabled services, where IRS guidance is sparse and private letter rulings are relied upon heavily. In our practice, most venture-backed software companies clear the bar; vertically-integrated services businesses with software components are often a closer call and merit a PLR-oriented analysis before the exit.
Two estate-planning techniques effectively multiply the QSBS benefit beyond the per-taxpayer $10 million cap: gifting shares to non-grantor trusts (each of which is a separate taxpayer for Section 1202 purposes) and, for founders with significant equity, making modest early gifts to adult children who will then hold through to exit in their own capacity. Both techniques require clean execution — the five-year holding period tacks only for certain transfers, the gift tax cost must be understood at the point of transfer, and the state tax treatment varies (Massachusetts does not conform to Section 1202; Rhode Island does).
Traps we see routinely: issuing founder stock and then taking it back to reissue (new holding period starts); redemptions within two years of issuance that exceed statutory de minimis thresholds; convertible note conversions timed poorly relative to the five-year clock; and secondary sales by founders that don't appreciate that the holding period is tested at the share level, not the shareholder level.
Section 1202 planning is, in our experience, one of the highest-leverage items a founder can address at formation and one of the hardest to rescue later. A thirty-minute structuring conversation at incorporation is routinely worth seven figures at exit.
