§1202 Maximization —
Structure Matrix & Qualification Rulebook

For a build-to-sell platform with passive ownership and operators in place. Scored on a single objective: maximizing the gain excluded under IRC §1202 across a serial sequence of business exits.

Post-OBBBA · stock issued after 07/04/2025 $75M gross-asset cap $15M / 10× per-issuer cap 3 / 4 / 5-yr tiered exclusion

Bottom line, viewed only through §1202

The structure that minimizes tax returns — one C corp holding disregarded single-member LLCs — is the worst for maximizing §1202. It collapses everything into a single issuer with a single exclusion cap, usable only once, on a sale of the whole platform; selling any one business is a deemed asset sale with no exclusion and corporate double tax. To maximize §1202 in a serial build/sell model you do the opposite: one qualifying C corp per business = one fresh issuer cap per business, then multiply caps further across non-grantor trusts and family. More returns is the price of more exclusion — and the exclusion is worth far more than the compliance.

Quick disqualifier screen

Tick anything true of a candidate business or its issuer. Any single tick puts §1202 at risk — these are the fastest ways to lose the exclusion before you ever get to structuring.

Clear so far

Nothing flagged. If the issuer is a C corp under the gross-asset cap and ≥80% of assets are used in a qualified active business, the stock can be QSBS. Confirm the 80% test holds for substantially all the holding period, not just at issuance.

Qualification rulebook

Both gates must be cleared. The corporate-level tests govern whether the stock is QSBS; the shareholder-level tests govern whether you can claim the exclusion and how much.

Corporate level — the issuer

Domestic C corporation at issuance and substantially all the holding period. S-corp-era stock does not qualify; an LLC must elect C-corp treatment.
Gross-asset cap. Aggregate gross assets ≤ $75M ($50M for stock issued on/before 7/4/2025) at all times before and immediately after issuance. Contributed property counts at FMV, not basis. Breach is permanent for stock already issued.
80% active-business test. ≥80% of assets by value used in the active conduct of one or more qualified trades or businesses — for substantially all the holding period.
Qualified trade or business. Must not be an excluded field (see screener). Operators running the business count as active conduct; owner passivity is irrelevant.
Real-estate limit. Fails if >10% of net assets is real property not used in an active QTB. Rental/holding real estate does not count as active.
Portfolio limit. Fails if >10% of net assets is stock/securities of non-subsidiaries.
Working-capital safe harbor. Cash/investments for reasonable working capital or R&E count as active-business assets for up to 2 years (longer in genuine startup/R&D).
Look-through. A >50%-owned corporate sub: parent is deemed to own its ratable share of the sub's assets/activities. A disregarded SMLLC collapses fully into the parent.

Shareholder level — the holder

Non-corporate holder. Individuals, or a passthrough that routes the exclusion through under §1202(g).
Original issuance. Stock acquired directly from the corporation for cash, property (not stock), or services.
Holding period (post-7/4/25 stock): 3 yr → 50%, 4 yr → 75%, 5 yr+ → 100% exclusion. Pre-7/5/25 stock: 5 years for its applicable %.
Per-issuer cap. Excludable gain = greater of $15M ($10M pre-7/5/25) or 10× aggregate adjusted basis of the issuer's QSBS sold that year. Per taxpayer, per issuer — this is the lever you multiply.
§1202(g) passthrough. A partnership or S corp may hold QSBS; the exclusion flows to a partner/shareholder who held the interest when the QSBS was acquired and continuously through the sale, capped at their interest at acquisition.
28% rate on the taxable slice. Gain not excluded (the 50%/75% tiers) is taxed at the 28% §1202 rate, above the normal 15/20% LTCG rate — a reason to hold to five years where possible.

Structure decision matrix

Four architectures, ranked by how much §1202 exclusion they generate across a build/sell sequence. "Caps available" is the maximization metric — distinct issuer caps you can stack across businesses and taxpayers.

Structure	§1202 rank caps generated	Per-business QSBS exit	Gross-asset headroom	Contamination risk	Returns	Operator-equity fit	Best when
Parallel C corps one issuer per business	★ MaximumOne $15M/10× cap per business; multiply across non-grantor trusts & family.	✓ YesSell one C corp's stock; clean QSBS.	$75M eachSeparate ceiling per entity.	IsolatedA bad line can't taint the others.	High1120 per business (+ holdco).	GoodOperators get stock/options in their own corp; mind redemption rules.	Serial build/sell of qualifying operating businesses with sizable exits. The §1202 maximizer.
Partnership holdco over C-corp subs §1202(g) passthrough	★ Near-maxEach sub is a separate issuer; caps pass through to partners per §1202(g).	✓ YesSubject to §1202(g) holding conditions.	$75M eachPer sub.	IsolatedPer-sub qualification.	Highest1065 holdco + 1120 per sub.	ModerateProfits interests at holdco affect each partner's ratable §1202(g) share.	You want consolidated personal reporting + trust/family stacking as partners, with QSBS on each sub.
Single C corp + disregarded SMLLCs one tax return	✕ WeakestOne issuer → one cap, usable once, only on a whole-platform sale.	✕ NoPer-business sale = deemed asset sale, double tax, no §1202.

Then single-tax flexibility wins.

The operator-equity trap. Giving an operator any real equity — a membership interest or even a profits interest — converts a single-member LLC into a partnership that files its own return, regardless of the holding structure. The "one return" advantage of disregarded SMLLCs survives only if operators are paid contractually (salary, bonus, phantom equity, SARs, deal-based payouts) with no actual ownership. If operators will own a slice, you are filing separate returns either way — so structure each entity to be cleanly sellable and stop optimizing for return count.

Maximization levers

Once the businesses qualify, these are the moves that multiply the exclusion. The first two do most of the work.

01 · Stack issuers

One qualifying C corp per business = one fresh $15M/10× cap each. The single biggest lever — and the reason the single-C-corp structure underperforms.

02 · Stack taxpayers

Gift QSBS to non-grantor trusts and family members before sale — each is a separate taxpayer with its own per-issuer cap. Gifts tack the holding period.

03 · Work the 10× lever

The cap is the greater of $15M or 10× basis. Contributing high-FMV property at issuance raises the 10×-basis ceiling well above $15M.

04 · Issue early & low

Issue stock while gross assets are well under $75M to lock QSBS status and start the clock. The cap also resets as assets spend back down below the ceiling.

05 · Route via §1202(g)

A partnership/S corp can hold the QSBS and pass the exclusion to qualifying partners — useful for trust/family stacking under one holdco.

06 · Hold to five years

Reach the 100% tier and avoid the 28% rate on the 50%/75% taxable slice. Use the 3/4-yr tiers only as a liquidity fallback.

07 · Guard the 80% test

Keep real estate <10%, non-qualified activity <20%, and portfolio securities <10% — for substantially all the hold, not just at issuance.

08 · Avoid redemptions

Significant redemptions from the holder or related persons near issuance can taint the stock. Keep capital activity clean around the issuance window.
