QSBS Planning for Founders
Qualify, protect, and multiply the Section 1202 exclusion before your liquidity event — not after.
Qualified Small Business Stock (QSBS) is one of the largest tax breaks in the U.S. tax code, but it is also one of the easiest to forfeit. The rules are set at issuance, the clock starts on the acquisition date, and most of the planning that expands the exclusion has to happen years before a term sheet is signed. This guide covers what QSBS planning actually involves for founders — and how Frame helps you track eligibility, model outcomes, and prepare for the sale.
What is QSBS planning?
QSBS planning is the ongoing process of establishing, preserving, and expanding your eligibility for the Section 1202 capital gains exclusion. It is not a one-time filing — it is a set of decisions across incorporation, share issuance, holding period, residency, and trust structure that determine how much of your exit is tax-free at the federal level.
- Confirm the company met the §1202 gross-asset test at issuance
- Document acquisition date and cost basis for every lot
- Track the 5-year holding clock (or the OBBBA tiered clock for stock issued after July 4, 2025)
- Model residency and state-conformity risk before the sale
- Evaluate non-grantor trust stacking to multiply the per-taxpayer cap
The §1202 exclusion in plain English
For QSBS held at least five years, eligible shareholders can exclude the greater of $10 million or 10× the aggregate adjusted basis of qualifying stock from federal capital gains tax. Stock issued on or after July 4, 2025 falls under the OBBBA tiered regime, which introduced a 50% exclusion at 3 years, 75% at 4 years, and 100% at 5 years. The exclusion is per taxpayer, per issuer — which is why trust stacking can meaningfully change the math on a large exit.
The most common QSBS mistakes we see
By the time most founders talk to a specialist, at least one of these has already happened. The good news is that early tracking catches most of them while there is still time to fix.
- Missing documentation of the gross-asset test at issuance
- Losing eligibility through a company redemption or reorganization
- Selling before hitting the 5-year mark to fund a life event
- Living in a non-conforming state (California, New Jersey, Pennsylvania) on the sale date
- Skipping trust planning until after the term sheet — when valuations spike
Frequently asked questions
When should I start QSBS planning?
The day the company issues stock. Eligibility is set at issuance, the holding clock starts on the acquisition date, and the trust and residency planning that expands the exclusion typically takes 6–24 months to execute cleanly.
Can I still do QSBS planning if I already have stock?
Yes. Documentation cleanup, trust stacking, residency planning, and modeling the tiered vs. legacy regime can all be done after issuance. Some strategies (like non-grantor trust gifting) work best before a signed term sheet raises the valuation.
Does QSBS cover state taxes?
It depends on the state. Most states conform to the federal §1202 exclusion, but California and a handful of others do not. On a large exit, that gap alone can be worth restructuring your residency before the sale date.
How much can trust stacking save?
Each properly structured non-grantor trust can hold its own $10M / 10× basis exclusion. For founders with a large gain and multiple beneficiaries, this can multiply the excluded amount several times over — but only if the trusts are funded and seasoned before the sale.
