Section 1202 is one of the most powerful tax breaks ever written into the U.S. tax code — and most founders either don't know it exists or find out too late to plan around it.
The short version: if you hold Qualified Small Business Stock (QSBS) issued by a C-corporation for more than five years, you can exclude up to 100% of your federal capital gains from that stock — up to $10 million per taxpayer per issuer, or 10x your adjusted cost basis, whichever is greater. At a 23.8% federal long-term capital gains rate (including the 3.8% net investment income tax), that's up to $2.38 million in federal taxes eliminated on a $10M gain.
But whether New York State conforms to that federal exclusion is the question that matters most for the thousands of founders building companies in NYC — and the answer is no.
What Section 1202 Actually Requires
The federal QSBS exclusion under IRC Section 1202 has specific qualification criteria that must be met at both the company level and the investor level. Meeting all of them is more straightforward than most founders realize — especially if you're raising a seed or Series A round as a C-corp.
Company must be a C-corp
LLCs, S-corps, and LPs don't qualify. Delaware C-corps are the standard vehicle.
Aggregate gross assets ≤ $50M
At issuance and immediately after. Most seed and Series A companies qualify easily.
Active business requirement
Must be in a qualified trade. Finance, hospitality, law, healthcare, and a few others are excluded.
Original issuance only
Stock must be acquired directly from the company, not on the secondary market.
Held for 5+ years
The full exclusion requires a holding period of more than five years from issuance.
Domestic C-corp
Foreign-incorporated entities or their subsidiaries don't qualify for Section 1202.
The Federal Math: What You Actually Save
The exclusion is per taxpayer, per issuer — which means each founder, angel, and early employee who holds their own shares independently can claim separate exclusions. Here's what the federal savings look like across different exit scenarios:
| Exit Gain | Federal Tax (No QSBS) | Federal Tax (With QSBS) | Federal Savings |
|---|---|---|---|
| $2M | $476K | $0 | $476K |
| $5M | $1.19M | $0 | $1.19M |
| $10M | $2.38M | $0 | $2.38M |
| $20M | $4.76M | $2.38M* | $2.38M |
| $50M | $11.9M | $9.52M* | $2.38M |
*Assumes 23.8% federal LTCG + NIIT rate. Gains above $10M cap taxed normally. Each taxpayer's exclusion is independent.
Does New York Conform to the Federal QSBS Exclusion Under Section 1202?
No. This is the core issue for every New York-based founder. New York State has not adopted the federal Section 1202 exclusion. When you file your NY state return, the gain you excluded at the federal level gets added back in — you pay New York tax on the full amount.
What NY Non-Conformity Means in Dollars
On a $10M QSBS gain for a NYC resident:
New York treats capital gains as ordinary income, and it doesn't recognize the federal exclusion as modifying the character or amount of income for state purposes. The gain flows through on your NY return at the full amount, taxed at the top marginal rate for your income level.
Which States Do and Don't Conform to Section 1202
State conformity to Section 1202 varies significantly. The non-conforming states are mostly high-tax states with large founder populations — which is exactly why this planning issue matters so much.

Conforming or No-Tax States (Full federal benefit)
State tax law changes frequently. Consult a qualified tax advisor and verify current conformity status in your state before relying on QSBS planning.
QSBS Planning Strategies That Still Work for NY Founders
Non-conformity doesn't eliminate QSBS value for New York founders — it just changes the calculus. The federal savings are still enormous. And there are legitimate planning strategies that can reduce or eliminate the state-level exposure.
Relocation before exit
Medium complexityMoving from New York to a conforming or no-income-tax state before a liquidity event can eliminate the state tax entirely. The move must be genuine — domicile change, changed residency status, physical presence, driver's license, voter registration. NY aggressively audits high-income taxpayers who claim non-residency in an exit year.
QSBS stacking
Low risk if done earlyEach taxpayer gets a separate $10M per-issuer exclusion. Founders who issue stock to multiple family members, trusts, or entities at issuance — when the company is truly early-stage and the stock has minimal value — can multiply the total federal exclusion. This is a legitimate strategy but requires careful structuring well before any expected liquidity.
Section 1045 rollover
Time-sensitiveIf you sell QSBS before the 5-year mark, you can defer the gain by rolling proceeds into another qualifying QSBS company within 60 days. The new stock inherits the holding period of the original stock, so you don't restart the clock. This is especially useful for founders who take secondary sales before a company reaches liquidity.
Charitable giving of QSBS
IrreversibleDonating QSBS to a donor-advised fund or charitable organization can eliminate both federal and state capital gains on the donated shares, while generating a charitable deduction equal to the fair market value. This strategy is powerful for founders with highly appreciated QSBS who also have philanthropic goals.
The Legislative Outlook: Will NY Conform?
There have been periodic proposals in Albany to adopt New York QSBS conformity. The argument is straightforward: non-conformity makes New York a less attractive place to found and exit a company, which undermines the city's startup ecosystem relative to Miami, Austin, and other emerging tech hubs.
The counter-argument is equally simple: New York needs the tax revenue, and most QSBS beneficiaries are wealthy founders and investors. Conformity would disproportionately benefit high-income taxpayers in a state that has consistently moved toward higher rates at the top of the income distribution.
As of 2026, New York has not adopted conformity. The NY QSBS dashboard at Value Add VC tracks the current legislative status and any changes to state tax treatment of Section 1202 gains. The most realistic planning assumption for a New York founder today is that state taxes will apply on any QSBS exit — and strategy should be built around that baseline.
Section 1202 is still the single most powerful tax break available to startup founders.
New York non-conformity doesn't change that math at the federal level — it just means your state tax bill can't be zeroed out without a move or careful structuring from day one.
