Multiply your
QSBS exclusion

QSBS trust stacking lets eligible founders multiply the $15M per-taxpayer Section 1202 exclusion across properly structured non-grantor trusts — turning one exclusion into several.

GAIN EXCLUSION MATH

$15 Million

The federal QSBS gain exclusion per taxpayer, per issuer (stock issued after July 4, 2025 under OBBBA).

$60 Million

Founder/Investor + spouse + two non-grantor trusts. Four taxpayers.


Same exit. Same equity. Very different return to the family.

FIGURE 2 — FEDERAL TAX OWED AT EXIT

On a $200M exit, a four-taxpayer stack may shelter roughly $14M more in federal tax than a single taxpayer — same exit, same equity.

HOW THE STRATEGY WORKS (4 STEPS)

Identify

Confirm eligibility and model the stack against the founder's cap table.

Transfer

Gift qualifying stock well before a liquidity event. Gifting inside 12 months of a signed LOI is a no-go zone —recharacterization risk spikes.

Design

Choose the right structures. SLATs (grantor) do NOT stack; SLANTs, NGTs, non-grantor IDGTs do.

Realize

At exit, each properly structured trust claims its own §1202 exclusion.

Dogpatch brings the advisory relationship. Promissory brings the trust infrastructure — drafting, valuation, and administration.
