Qualified Small Business Stock §1202

"Your startup IPOs. You sell $15 million of founder stock. Federal tax bill: zero. The most generous provision in the Internal Revenue Code, and the One Big Beautiful Bill Act just made it better."

Typical Savings: Up to $3.6M federal per issuer Difficulty: ★★★★☆ Audit Risk: Medium Best For: C-corp founders & early employees

The 60-second pitch

§1202 of the Code lets non-corporate shareholders of a Qualified Small Business (QSB) exclude 100% of their gain on sale, up to a cap, after holding the stock for at least 5 years. It is the single most valuable provision available to startup founders and early employees.

The 2025 OBBBA upgrade (effective for stock issued after July 4, 2025):

Cap raised from $10M to $15M per issuer (or 10x basis if greater) — indexed for inflation starting 2027.
Aggregate asset threshold raised from $50M to $75M — more companies qualify at issuance.
New tiered exclusion: 50% after 3-year hold, 75% after 4-year hold, 100% after 5-year hold. Earlier exits get partial benefit instead of nothing.

For stock issued on or before July 4, 2025: the old rules still apply — $10M / 10x cap, 5-year hold, 100%-or-nothing exclusion, $50M asset cap at issuance.

The wrinkles are real: must be a domestic C-corp (no S-corps, no LLCs), at original issuance (not secondary buys), in a qualified trade or business (no financial services, no farming, no hotels/restaurants), and you can't redeem prior to or shortly after issuance. But when the wrinkles line up — and they do for most software, biotech, hardware, and product companies — it's the most lopsided risk/reward in tax planning.

Real-world example

Aisha · Co-founder · Series A SaaS startup

The setup. In August 2025 Aisha and her co-founder form CloudClerk, Inc. as a Delaware C-corporation. She buys 4,000,000 shares of founder common stock at $0.0001/share. Her basis: $400. They issue the stock fresh — original issuance.

The qualifying business. CloudClerk builds invoicing software for small businesses. That's a "qualified trade or business" under §1202(e)(3) — not a disqualified service business. The company raises $5M Series A in January 2026 at a $25M post-money valuation. Aggregate gross assets at issuance: $5.4M. Well under the new $75M cap.

The hold. Aisha holds her shares from August 2025. She reaches 5 years in August 2030. The company grows. In December 2032 (year 7), CloudClerk is acquired by a strategic buyer for $300M cash.

The exit math. Aisha owns 20% of fully-diluted shares post-financing. Her sale proceeds: $60,000,000. Her basis: $400. Gain: $59,999,600.

The §1202 exclusion (post-OBBBA stock). Cap per issuer = greater of $15,000,000 or 10× basis ($4,000). Cap = $15,000,000. $15M of her gain is federal-tax-free. Remaining $45M is taxed at 20% LTCG + 3.8% NIIT = $10.71M federal. Without §1202, she would have owed $14.28M federal. §1202 saves her $3,570,000 in federal tax.

The stacking move. Years before the sale, Aisha gifts 1,000,000 shares to an irrevocable trust for her kids. The trust is a separate taxpayer with its own $15M §1202 cap. On the same sale, the trust excludes another $15M of gain. Combined family savings: ~$7.14M federal. If she'd also gifted to a spouse and a non-grantor trust for her parents, the stack could exceed $40M of total tax-free gain on a single liquidity event.

The step-by-step checklist

Form as a domestic C-corporation at inception. S-corps, LLCs, and partnerships don't qualify, even if they convert to C-corp later (the holding period starts at conversion at FMV — old appreciation doesn't get §1202). Delaware is the standard.
Verify the trade or business is qualified under §1202(e)(3). Disqualified: health, law, engineering, architecture, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage, banking, insurance, financing, investing, farming, mineral extraction, hotels, restaurants. Qualified: software, hardware, manufacturing, biotech, e-commerce, most product businesses.
Confirm gross assets ≤ $75M at and immediately after issuance (post-OBBBA, for stock issued after July 4, 2025). Pre-OBBBA stock: ≤ $50M. Asset test is at issuance, not at sale — exceeding $75M later doesn't kill QSBS retroactively.
Acquire stock at "original issuance" from the company — cash, property (not stock), or services. Buying secondary shares from an existing holder does NOT qualify under §1202(c)(1)(B).
For employees: §1202 applies to stock acquired through option exercise, RSU vesting, or direct purchase — but the 5-year clock starts on the date you actually own the stock (option exercise date, not grant date).
Document the date and basis at acquisition. Cap table records, stock certificates, option exercise notices. Keep these for life — the §1202 holding period is forever evidentiary.
The company must use ≥ 80% of assets in active conduct of a qualified trade or business during "substantially all" of your holding period. Operating company test, not a holding company.
Avoid disqualifying redemptions. If the company redeems shares from you (or "related parties") within 2 years before or after your acquisition, your QSBS status can be tainted under §1202(c)(3). Plan around this.
Hold for at least 5 years for the 100% exclusion. Post-OBBBA stock: tiered partial — 50% at 3 years, 75% at 4 years. Pre-OBBBA: all-or-nothing at 5 years.
If forced to sell before 5 years: do a §1045 rollover. Reinvest proceeds into another QSBS within 60 days. The new stock's holding period tacks onto the original. Filed via Form 8949 with code "R."
For "stacking": gift shares to non-grantor trusts for children, spouse, or parents BEFORE the liquidity event. Each separate taxpayer gets its own $15M (or $10M, pre-OBBBA) §1202 cap. Coordinate with an estate attorney — gifts use lifetime exemption and require valuation discount work.
On sale, report on Form 8949 with code "Q" and the §1202 exclusion as a negative adjustment in column (g). Keep documentation showing all five tests met.

IRS code & authority

§1202(a) The core exclusion. 100% (or 50%/75% under OBBBA tiered rules) of gain on sale of QSBS held > 5 years (or 3/4 years post-OBBBA for partial).
§1202(b) The per-issuer cap: greater of $15M (post-OBBBA, indexed) or 10× aggregated adjusted basis. Pre-OBBBA stock: greater of $10M or 10× basis.
§1202(c) Defines QSBS. Original issuance, domestic C-corp, gross assets ≤ $75M (post-OBBBA) or ≤ $50M (pre-OBBBA) at and immediately after issuance.
§1202(c)(3) Anti-redemption rules. Significant redemptions from you (or related parties) within 2 years before or after issuance taint QSBS status.
§1202(d) "Qualified small business" — the gross asset cap test, measured at issuance.
§1202(e)(3) "Qualified trade or business" — the long list of disqualified service businesses. Tech and product companies generally qualify.
§1202(h) Tacking of holding period in tax-free transfers — gifts, inheritance, and certain reorgs preserve QSBS status and holding period.
§1045 Rollover. Sell QSBS held > 6 months, reinvest in new QSBS within 60 days, tack holding period. Saves the 5-year clock when forced to sell early.
One Big Beautiful Bill Act (P.L. 119-21, July 4, 2025) Raised cap from $10M to $15M, asset threshold from $50M to $75M, introduced tiered 50%/75%/100% exclusion. Applies to stock issued after July 4, 2025.
Form 8949 (Code Q) The §1202 exclusion election on the return.
Form 8949 (Code R) The §1045 QSBS rollover election.

Audit risk flags

"Qualified trade or business" challenge. Health-adjacent, consulting-adjacent, and "platform" businesses get pushed back on. Defense: Document the operating company's actual revenue activities. Software companies that sell to dentists are still software companies — but a "dental practice management" company that mostly performs services may be argued either way.
Original-issuance dispute. Buying shares from a departing co-founder or early employee = secondary purchase = no §1202 on those shares. Defense: All your founder/early shares should come directly from the corporation.
Asset test miscalculation. Often blown when the round closes just after a previous fundraise — the company may exceed $75M (or $50M pre-OBBBA) momentarily. Defense: Test gross assets immediately before AND immediately after issuance.
S-corp / LLC conversion to C-corp. The holding period starts at conversion, and the basis is FMV at conversion. Pre-conversion appreciation is NOT QSBS-eligible. Defense: Form as C-corp from day 1 if §1202 matters.
Redemption taint. Significant share repurchases within ±2 years of your stock issuance can disqualify all stock issued in that window. Defense: Avoid buybacks near financings. If unavoidable, restrict to the 5% safe harbor under Reg §1.1202-2.
"Substantially all" failure during hold. If the company pivots to a disqualified business (e.g., becomes a hedge fund) for a meaningful portion of your hold, QSBS may be tainted. Defense: Don't sell the share if a pivot might disqualify; structure pivots carefully.
Improper stacking gifts. Gifts to "incomplete" gift structures (revocable trusts, your own grantor trust) don't give you a separate §1202 taxpayer. Defense: Use non-grantor trusts, properly structured, with separate trustees and EIN. Engage trust attorney.
State conformity. California (NJ, Massachusetts, Pennsylvania, others) does NOT conform to §1202. You owe state tax on the full gain even with full federal exclusion. Defense: Consider state residency planning before sale.

When NOT to do this

You're forming an LLC or S-corp. Pass-through entities don't qualify. If §1202 might matter at exit, organize as a C-corp from inception (or commit to a §351 incorporation early).
You're in a disqualified trade or business. Law firms, accounting firms, medical practices, consulting shops, financial advisors. Don't waste time chasing §1202 — your structure simply doesn't qualify.
You'll sell in < 3 years. Pre-OBBBA stock gets nothing under 5 years. Post-OBBBA stock gets nothing under 3. If you know the exit is imminent, the §1202 setup overhead may not pay back.
You bought stock secondary. Buying shares from a departing founder or in a tender offer = no §1202 unless the original holder transferred to you via gift/inheritance (which tacks the holding period under §1202(h)).
The company will exceed $75M assets imminently. If you're joining post-Series C and the company has $200M in cash, the asset test was likely blown long ago for shares issued after that point. Your shares may not qualify.
You're in a high-conformity state with no easy way to change residency. California, Massachusetts, NJ, PA don't recognize §1202. You'll still owe state cap gains tax on the full $15M.
The C-corp form creates double-taxation drag. If the company will throw off operating profit (not just appreciation), C-corp double tax on dividends might outweigh the QSBS savings. Model both paths.

Disclaimer. §1202 is the most reward-rich and rule-heavy provision in the Code. Even small structural errors — secondary purchase, redemption within 2 years, S-corp parentage, disqualified-business activities — can destroy a multimillion-dollar exclusion. Always work with both a tax professional and a startup attorney before formation, before financing, and well before exit. The OBBBA changes summarized here apply to stock issued AFTER July 4, 2025. Earlier-issued stock follows the prior $10M / 5-year / $50M / 100%-only rules.
