QSBS §1202 Expanded: $15M Cap and 3/4/5-Year Tiers—Compliance Planning for C-Corp Startups

Author: Gloria Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line in one breath

OBBBA (P.L. 119-21, signed July 4, 2025) expanded IRC §1202 Qualified Small Business Stock (QSBS). For stock acquired after July 4, 2025, the gain exclusion is 50% / 75% / 100% after holding 3 / 4 / 5 years; the per-taxpayer, per-issuer dollar cap rises to $15 million ($7.5 million if married filing separately) or 10× adjusted basis (greater of); and the issuer’s aggregate gross-assets limit rises from $50 million to $75 million. Pre-enactment stock generally keeps the old rules (typically more than five years and a $10 million class cap). As of September 2026, Cary/RTP founders and angels who want QSBS at exit need compliance planning on entity choice, issuance, and holding-period records—not a label added after the fact.

Background

Section 1202 has long allowed noncorporate taxpayers to exclude up to 100% of gain on qualifying original-issue stock of a domestic C corporation that meets active-business and asset tests, subject to a per-issuer cap. OBBBA added shorter holding-period tiers, a higher dollar cap, and a higher asset threshold for newly acquired QSBS, with inflation indexing of the new bases for tax years beginning after 2026. Partnerships and S corporations are generally not QSBS issuers. Many founders default to LLCs or S corps; if QSBS is a goal, evaluate a C corporation before financing—and accept the double-tax and state-tax tradeoffs.

Old vs. new

1. Holding period (new stock): Old path usually required more than 5 years for 100% → new stock: 3 years 50%, 4 years 75%, 5 years 100%.

2. Dollar cap (new stock): Old $10 million (MFS $5M) or 10× basis → new $15 million (MFS $7.5M) or 10× basis; post-2026 inflation figures 待核.

3. Issuer assets: Old $50 million → new $75 million, tested before and immediately after issuance.

4. Old stock: Acquired on or before July 4, 2025 generally stays on old holding-period and cap rules—stacking with new stock of the same issuer needs a fact-specific analysis (待核).

5. Who qualifies: Primarily individuals and other noncorporate shareholders; C corporation shareholders generally do not.

6. Issuance: Must be original issue for money, property, or services; secondary-market purchases usually fail.

7. Active business: Qualified trade or business tests still apply; certain industries have long been limited—confirm the statutory list (待核).

8. North Carolina: Whether NC fully conforms to the federal exclusion—check NCDOR before filing (待核).

Self-check: does this affect you?

1. You will take original-issue C corp stock as a founder or angel and expect exit gain years later.

2. A financing round may push aggregate gross assets near the $75 million test.

3. You are in an LLC/S corp today but investors want a “QSBS-friendly” C corp.

4. You hold both pre- and post-July 4, 2025 blocks in the same issuer and are unsure about the $10M vs $15M caps.

5. You heard “three years means fully tax-free” without distinguishing the 50% tier from the 100% five-year rule.

Simplified examples (illustration only; ignores state tax, NIIT, redemptions, preferred terms)

Example A — five years / 100%: Cash subscription for qualifying original-issue shares in August 2025; $500,000 basis; $8 million gain on a 2031 sale within the per-issuer cap. Illustration: if all QSBS tests are met, the gain may be 100% excludable (still subject to the $15M / 10× limit).

Example B — three years / 50%: Same stock sold just after three years with $4 million of gain. Illustration: roughly $2 million may be excluded (50%); the rest remains taxable capital gain—rate details including any 28% class rules 待核.

Example C — asset test: Post-round assets reach $80 million. Illustration: that round’s original-issue shares may fail entirely—run the asset test before closing.

Action timeline

1. Before financing: Confirm domestic C corp status; model pre/post-issuance assets; screen disqualified industries.

2. At closing: Keep subscription docs, funding proofs, cap table, and holding-period start dates.

3. During hold: Watch redemptions, related-party deals, and business-mix changes that can spoil eligibility.

4. Pre-exit: Model 3/4/5-year tiers and the $15M cap on an after-tax basis; add NC (待核).

5. Old + new blocks: Separate acquisition dates so caps are not mixed incorrectly.

What YCL can do

1. Stress-test entity choice and QSBS risk points before a raise or reorganization.

2. Build workpapers for original issue, holding period, and the asset test.

3. Model 50%/75%/100% outcomes and dollar-cap headroom; flag state conformity (待核).

4. Coordinate counsel letters and tax files to reduce exam friction.

5. Bilingual help from Cary (RTP) and Shanghai with CPA Chenchen Liu and Gloria—compliance planning.

FAQ

Q: Does every startup share become tax-free after three years?

A: No. Original issue, C corp, asset, and active-business tests still apply—and three years generally means a 50% exclusion, not automatic 100%.

Q: Can pre-July 4, 2025 shares use the new $15 million cap?

A: Generally they stay on the old rules; combining old and new blocks of the same issuer needs a facts-and-circumstances analysis (待核).

Q: Does North Carolina also exclude the gain?

A: Follow current NCDOR conformity to federal §1202 (待核); do not assume a perfect federal match.
