QSBS has existed for years, but the way funds have to manage it has changed.
Since mid-2025, we’ve seen:
Legislative expansion of QSBS eligibility
Longer private holding periods becoming the norm
More partial liquidity through tenders and secondaries
More LP questions around tax treatment and documentation
Taken together, QSBS is no longer something most funds can think about only at exit. It’s something that now shows up throughout the life of an investment.
This post pulls together the most recent updates, how they fit with what we’ve written before, and how funds are approaching QSBS today.

QSBS 2.0: The 2025 Expansion and Why It Matters
In July 2025, legislation expanded QSBS eligibility for shares issued on or after July 4, 2025. Our friend, Chris Harvey covered this well in his post #33 Episode - QSBS 2.0 is Here, and we previously walked through the implications in #255: QSBS 2.0 – Faster Exits, Bigger Caps, New Playbooks.
The core changes:
Company asset threshold increased
From $50M to $75M at issuanceIndividual exclusion cap increased
From $10M to $15M (or 10x cost basis)Holding period now phases in
3 years → 50% exclusion
4 years → 75% exclusion
5 years → 100% exclusion
For earlier issuances, the prior rules still apply.
This expansion made QSBS relevant for more companies and more shareholders — but it also introduced another layer of tracking. Funds now need to understand which shares fall under which regime.
What Hasn’t Changed
Despite the expansion, the fundamentals are the same:
QSBS is a shareholder-level benefit, not a fund-level one
Eligibility is determined at issuance, not retroactively
Structure, timing, and documentation matter
QSBS benefits can be lost through routine operational actions
We’ve covered these basics before — including in #224: More VC Fund Tax & QSBS Detail and earlier in #215: VC Fund Taxes Simplified & QSBS — and they still hold.
A Quick Refresher: What QSBS Actually Is
Qualified Small Business Stock (QSBS) is a federal tax incentive under IRC Section 1202, intended to encourage people to start companies, invest early, and take employment risk.
If the requirements are met, eligible shareholders may be able to exclude some or all federal capital gains taxes on the sale of qualifying stock, subject to caps.
QSBS can apply to:
Founders
Employees
Angel investors
Individual GPs and LPs
It does not benefit the fund entity itself, and it does not change reported fund returns.
Where QSBS Tends to Break Down in Practice
In 2026, QSBS issues are less about edge-case law and more about day-to-day execution.
Common friction points we still see:
Share repurchases or tender offers that affect eligibility
Companies crossing the asset threshold during financings
Business model changes that introduce non-qualifying activity
Secondary transactions that create mismatched expectations
Incomplete or inconsistent documentation across rounds
Most of these aren’t controversial. They’re easy to miss if QSBS isn’t actively tracked.
An Illustrative Example (Why Funds Still Care)
We’ve previously referenced a simplified example from Sapphire Ventures showing how QSBS can materially change after-tax outcomes for founders, angels, and fund stakeholders — without changing valuation.
The lesson wasn’t that QSBS always applies, or that exits should be optimized around it. It was that when QSBS does apply, the difference in after-tax proceeds can be meaningful.
That lesson still holds — especially as exits stretch and liquidity becomes more incremental.
How Funds Are Approaching QSBS Today
There isn’t a single playbook, but in practice we see funds:
Evaluating QSBS eligibility at the time of investment
Revisiting assumptions after financings, restructures, or tenders
Tracking issuance dates and holding periods by tranche
Using more formal QSBS documentation and attestations, often informed by practical guidance and educational resources such as AngelList’s QSBS overview, especially as LP reporting expectations increase
Setting clearer expectations with LPs about tax treatment and limitations
None of this guarantees a benefit. It simply reduces surprises.
The Bottom Line
QSBS didn’t change venture economics. It changed the margin.
The 2025 expansion made QSBS relevant for more companies. The 2026 environment — longer holds, partial liquidity, and more LP scrutiny — made it harder to treat as an afterthought.
QSBS works best when it’s understood early, revisited periodically, and communicated clearly. When it isn’t, the issues usually show up late, and options are limited.
