You built a company, took stock early, and now an exit is on the table. The federal QSBS exclusion under IRC Section 1202 may wipe out most of the federal tax. The question NJ founders keep asking: does New Jersey tax the gain anyway?
For years, the answer was yes — in full. Starting with tax year 2026, the answer changed. New Jersey now excludes QSBS gains that are exempt federally.
This guide answers the New Jersey question first, since most national coverage skips it. It then covers what OBBBA changed in July 2025, and what both changes mean for exit timing. Every figure below is sourced to the IRS, the U.S. Code, or the State of New Jersey.
What is the QSBS exclusion?
Qualified small business stock, or QSBS, is stock in a qualifying small C corporation. You generally must get the shares at original issuance — from the company, not another holder. The company must pass a gross-asset test when the shares are issued.
Hold the stock long enough, and IRC Section 1202 lets you exclude some or all of the gain. For founders and early employees, that can be the single largest tax break in an exit.
Two sets of federal rules now run side by side. Which set applies depends on when you acquired the stock — not when you sell it.
Does New Jersey tax Section 1202 gains?
Historically, yes — all of them. New Jersey’s Gross Income Tax never followed the federal QSBS exclusion.
A founder who owed $0 federal tax on a QSBS sale still owed New Jersey tax on the whole gain. NJ rates top out at 10.75%.
That changed with P.L. 2025, c.67, signed June 30, 2025. The law created N.J.S.A. 54A:6-34, a new exclusion in the Gross Income Tax Act.
It removes QSBS gains from NJ gross income. The exclusion applies “to the extent such gains or income are exempt from federal taxation” under IRC Section 1202.
Three points matter here:
- It is a straight federal piggyback. The enacted law adds no New Jersey-only tests — no NJ incorporation, payroll, or property rules.
- It starts with taxable years beginning on or after January 1, 2026. For nearly all individuals, that means calendar year 2026.
- It covers only the federally exempt portion. Gain the IRS still taxes stays fully taxable in New Jersey. That includes a 50% or 75% tier and any gain over the cap. NJ has no lower rate for capital gains.
The 2025 vs. 2026 timing trap
The effective date draws a sharp line. A QSBS sale that closed in calendar 2025 got the federal exclusion but no New Jersey exclusion. The same sale closing in 2026 may get both.
Consider a founder in Alpine with a $5 million QSBS gain. The stock was acquired in 2015, held more than five years, and sits under the $10 million cap.
The federal exclusion is 100%. Had the sale closed in December 2025, New Jersey could have taxed the full $5 million.
At the top 10.75% rate, that is roughly $537,500 of state tax. Close the same sale in 2026, and the New Jersey tax on that gain could potentially be $0.
Illustrative example — results vary. Your rate, cap usage, and eligibility depend on your facts.
The 2026 law does not reach back. If your deal closed in 2025, the gain stays on your NJ return for that year.
What OBBBA changed for stock acquired after July 4, 2025
The One Big Beautiful Bill Act (P.L. 119-21), signed July 4, 2025, rewrote Section 1202 for newly acquired stock. The new rules apply to stock acquired after July 4, 2025. Stock acquired on that date or earlier stays under the old regime.
The new 3–4–5-year holding tiers
The all-or-nothing 5-year cliff is gone for new stock. Section 1202(a) now phases the exclusion in:
- 50% after 3 years
- 75% after 4 years
- 100% after 5 years or more
Sell before the 3-year mark and you get no exclusion at all.
The $15 million per-issuer cap
For new-regime stock, the dollar cap rises to $15 million per issuer. The cap is the greater of that dollar limit or 10 times your basis in the shares sold.
Two reductions apply. Prior-year exclusions shrink the $15 million. So do current-year gains you take on old-regime stock of the same company.
The $15 million amount adjusts for inflation for tax years beginning after 2026.
The $75 million gross-asset test
A company can now be much larger at issuance and still mint QSBS. For stock issued after July 4, 2025, the gross-asset limit rises from $50 million to $75 million. That amount also indexes for inflation after 2026.
The old rules still govern stock you already hold
If you acquired your shares on or before July 4, 2025, nothing changed for you federally:
- Holding period: more than 5 years — all or nothing
- Exclusion: 100% only for stock acquired after September 27, 2010; earlier vintages get 50% or 75%
- Cap: $10 million per issuer, or 10 times basis if greater
- Company size: $50 million gross-asset test at issuance
Two traps hit people who hold both vintages. First, gains excluded on old-regime stock eat into the $15 million cap on new-regime stock of the same company.
Second, transfers do not reset the regime. Gifted, inherited, and Section 1045 rollover stock generally keeps the original acquisition date.
What the IRS — and New Jersey — still tax
The exclusion rarely covers everything. The taxable slice of a Section 1202 gain is taxed at a maximum 28% federal rate.
The 3.8% net investment income tax can also hit that taxable slice. The excluded portion escapes NIIT because it never enters gross income.
AMT is now mostly a non-issue. After OBBBA, the 7% preference under IRC Section 57(a)(7) applies only to stock acquired on or before September 27, 2010. If you still hold shares from that era, the preference lives on for those lots.
New Jersey mirrors the federal split. Whatever the IRS exempts, New Jersey exempts. Whatever the IRS taxes, New Jersey taxes at ordinary Gross Income Tax rates.
Exit timing for Bergen County founders and early employees
The acquisition date — not the sale date — picks your federal regime. The sale date picks your New Jersey treatment. Owners in this situation often work through four questions before a term sheet is signed:
- Which regime does each stock lot fall under? Grants, exercises, and secondary purchases can straddle July 4, 2025.
- Where does each lot sit against its cap? The $10 million and $15 million limits interact when one company issued both vintages.
- Does the sale land in a tax year that starts on or after January 1, 2026? For NJ purposes, that is the whole ballgame.
- What records prove it? Acquisition dates, basis, and the company’s asset-test support should be in the file before diligence starts.
A QSBS sale is usually one piece of a larger exit. Deal structure, earnouts, and escrow all change the tax picture. Our guide to the tax side of selling a business in New Jersey covers those moving parts.
Does the exit also mean selling the house and leaving the state? Read how the NJ exit tax and mansion tax really work.
One more gate: Section 1202 requires a C corporation. If your company is an S-corp or LLC, QSBS is off the table unless the entity converts. Pass-through owners have a different toolkit, starting with the NJ BAIT election.

Frequently Asked Questions
Does New Jersey tax QSBS gains in 2026?
Generally no. Starting with taxable years beginning on or after January 1, 2026, New Jersey excludes QSBS gains from Gross Income Tax. The exclusion comes from P.L. 2025, c.67, signed June 30, 2025, which created N.J.S.A. 54A:6-34. It covers only gain exempt federally under IRC Section 1202; the rest stays taxable in New Jersey.
What did OBBBA change for QSBS?
For stock acquired after July 4, 2025, OBBBA (P.L. 119-21) replaced the 5-year cliff with holding tiers. The tiers are 50% at 3 years, 75% at 4 years, and 100% at 5 years. OBBBA also raised the per-issuer cap from $10 million to $15 million. The company gross-asset limit rose from $50 million to $75 million, and both new amounts adjust for inflation after 2026.
Do the new QSBS rules apply to stock I already own?
No — stock acquired on or before July 4, 2025 keeps the old rules. Those rules are a more-than-5-year holding period, a $10 million or 10-times-basis per-issuer cap, and a $50 million gross-asset test. The 100% exclusion applies only if that stock was acquired after September 27, 2010. Gifted, inherited, or Section 1045 rollover stock generally keeps the original acquisition date.
Is a QSBS sale that closed in 2025 exempt from New Jersey tax?
No — the New Jersey exclusion applies to taxable years beginning on or after January 1, 2026. For nearly all individuals, that means calendar year 2026. A QSBS sale that closed in 2025 got the federal Section 1202 exclusion but stayed fully taxable in New Jersey. NJ Gross Income Tax rates run up to 10.75%.
How much QSBS gain can I exclude per company?
The cap is the greater of a dollar limit or 10 times the basis of the stock sold that year. The dollar limit is $10 million for stock acquired on or before July 4, 2025. For stock acquired after that date, the limit is $15 million. Gains you take on old-regime stock reduce the $15 million cap for new-regime stock of the same company.
Does the AMT apply to excluded QSBS gain?
Usually not anymore. After OBBBA, the 7% preference under IRC Section 57(a)(7) applies only to stock acquired on or before September 27, 2010. Excluded gain on stock acquired after that date carries no AMT preference. The taxable part of a Section 1202 gain is taxed at a maximum 28% federal rate.
