QSBS Section 1202 in 2026 (After OBBBA): The Founder Tax-Free Exit Rule

#What QSBS actually is

Section 1202 of the Internal Revenue Code is one of the most aggressive tax breaks in the entire code: if you hold qualifying small business stock long enough, you can exclude most or all of the capital gain when you sell.

The basics that have to be true for stock to qualify:

1. Issued by a domestic C-corporation (S-corps and LLCs don’t qualify — has to be a C-corp at the time of issuance)
2. Acquired at original issuance (you bought it directly from the company, OR received it as compensation, OR converted from a SAFE/convertible note — NOT secondary-market purchase)
3. Held continuously for the required holding period (post-OBBBA: at least 3 years; pre-OBBBA: at least 5 years)
4. The company’s aggregate gross assets were under the threshold immediately before AND at the time of issuance ($75M post-OBBBA for stock issued in 2027+; $50M for pre-2027 stock under OBBBA)
5. The company is in a qualifying trade or business — most operating businesses qualify; excluded: services in health, law, finance, accounting, consulting, performing arts, etc. (§1202(e)(3)). Most SaaS + product companies qualify. Tax firms do NOT qualify (we’re services).
6. The company actively conducted business during substantially all the holding period

When all 6 conditions are met, the exclusion applies. When not, it’s regular capital gains treatment.

#What OBBBA changed (effective for stock issued after July 4, 2025)

The One Big Beautiful Bill Act (signed July 4, 2025) made three substantive changes to §1202 — the biggest reform since the rule was enacted in 1993.

#Change 1: Tiered holding period replaces 5-year cliff

Pre-OBBBA rule (still applies to stock issued July 4, 2025 or earlier):

• Held < 5 years → 0% excluded, full capital gain taxed
• Held 5+ years → 100% excluded (up to the per-issuer cap)

Post-OBBBA rule (stock issued after July 4, 2025):

• Held < 3 years → 0% excluded
• Held 3 to <4 years → 50% excluded
• Held 4 to <5 years → 75% excluded
• Held 5+ years → 100% excluded

This is a major shift. Founders no longer have to wait the full 5 years to get any benefit — partial exclusion kicks in at year 3.

Important rate trap: For the portion NOT excluded under the tiered rule (the 50% or 25% remaining gain), the tax rate is 28% (the §1(h)(4) rate for §1202 gain) — NOT the standard 15-20% long-term capital gains rate. So a 50% exclusion at year 3 effectively means:

• Gain × 50% × 0% = excluded
• Gain × 50% × 28% = taxed at 28%

Compared to a regular sale at year 3 (which would be ordinary if held <1 year, but in this case held 3+ years = standard LTCG at 20%), partial QSBS exclusion may NOT always win. Math has to be run case-by-case.

#Change 2: Per-issuer exclusion limit raised from $10M to $15M

The greater-of rule:

• $15M per issuer (post-OBBBA, was $10M), OR
• 10× your basis in the stock

For most early employees who paid pennies for their stock options, the $15M cap is what matters. For founders who put real money into the company, 10× basis can sometimes be the bigger number.

The $15M cap is now inflation-adjusted annually starting 2026 — was previously fixed at $10M since 1993.

#Change 3: Gross-asset threshold raised from $50M to $75M (effective tax years after 2026)

The company qualifies as a “small business” if its aggregate gross assets (cash + cost basis of all property, including IP) were under the threshold immediately before AND at the time of stock issuance.

• Pre-OBBBA: $50M ceiling
• Post-OBBBA (effective tax years beginning after 2026): $75M ceiling, inflation-adjusted

This means more later-stage companies will qualify. A Series B or Series C company that crosses $50M in gross assets pre-OBBBA was already disqualified for new issuances; post-OBBBA, they can keep issuing QSBS up to $75M.

#The dollar math — pre-OBBBA vs post-OBBBA

Two worked examples to show the magnitude of the change.

#Example 1: Founder selling at year 5 (pre-OBBBA stock)

Sarah, founder of a SaaS company, exits in 2030 with $15M of capital gain on stock she’s held since 2022 (pre-OBBBA issuance, so old rules apply).

• Holding period: 8 years (>5) → 100% exclusion eligible
• Per-issuer cap: $10M (pre-OBBBA)
• Excluded gain: $10M
• Taxable gain: $5M
• Federal tax on $5M @ 20% LTCG + 3.8% NIIT = ~$1.19M
• Net to Sarah: $13.81M

#Example 2: Founder selling at year 5 (post-OBBBA stock)

Same Sarah, but the stock was issued in 2026 (after OBBBA). She sells in 2031 with $15M gain.

• Holding period: 5 years → 100% exclusion eligible
• Per-issuer cap: $15M (post-OBBBA, possibly $16M+ by 2031 with inflation)
• Excluded gain: $15M
• Taxable gain: $0
• Federal tax: $0
• Net to Sarah: $15M

Improvement vs Example 1: $1.19M of additional after-tax wealth. Just from the limit going $10M → $15M.

#Example 3: Founder selling at year 3 (post-OBBBA, partial exclusion)

Mike, an early employee, exits at year 3 with $4M of capital gain from acquisition.

Pre-OBBBA approach (if his stock had been issued before July 4, 2025):

• Holding period 3 yrs (<5) → 0% QSBS exclusion
• $4M gain taxed at 20% LTCG + 3.8% NIIT = ~$952K
• Net to Mike: $3.05M

Post-OBBBA (stock issued after July 4, 2025):

• Holding period 3 yrs → 50% exclusion
• Excluded gain: $2M
• Taxable gain: $2M @ 28% §1202 rate = $560K
• Net to Mike: $3.44M

Improvement vs pre-OBBBA: $390K. Mike gets to exit a year earlier than the old “wait 5 years” rule would have required, and still captures meaningful benefit.

#Operational planning — how founders + employees should think about this

The decisions QSBS changes:

#For founders deciding entity structure at incorporation

If you’re forming a new business and there’s any chance of substantial exit value (>$5M), strongly consider C-corp from day one. The QSBS exclusion only applies to C-corps. The S-corp election that saves you SE tax in the operating years can disqualify you from QSBS at exit — and the disqualification is permanent for that stock.

The math: $15M exit gain × 23.8% (LTCG + NIIT) = $3.57M of federal tax saved by being a C-corp at issuance. That’s massively bigger than any S-corp SE-tax savings over the operating years.

For ETS clients in the SaaS founder segment, this is a Day 0 decision we surface during initial advisory.

#For early employees deciding when to exercise options

If your company has issued stock after July 4, 2025 and you’re holding ISOs / NSOs:

• Exercise as early as possible to start the holding period clock. The clock starts when you ACQUIRE the stock, not when you receive the options.
• 3 years vs 5 years matters more now. Under the tiered rule, even a 3-year hold gets you 50% exclusion. The trade-off between “exit liquidity now vs $X more in exclusion later” is now more dynamic.

#For founders considering a sale before year 5

Pre-OBBBA: selling at year 4 meant losing 100% of QSBS benefit. Many founders held an extra year purely for the tax break.

Post-OBBBA: a year-4 sale captures 75% exclusion. The “hold for QSBS” pressure is much less acute. Liquidity events at year 3 or 4 are now legitimately on the table from a tax-planning standpoint.

#For employees joining a company that’s near the $75M threshold

Pre-OBBBA: a company that crossed $50M in gross assets stopped issuing QSBS-eligible stock. New employees got non-QSBS stock.

Post-OBBBA: more late-stage companies can still issue QSBS up to $75M gross assets. If you’re joining a $40-70M company starting 2027, ask the company whether they’re issuing QSBS-eligible stock.

#Common pitfalls (where founders lose the benefit)

#Pitfall 1: Doing an S-corp election after issuance

Once you elect S-corp status, you’re no longer a C-corp. New shares issued during the S-corp period don’t qualify for QSBS. Existing pre-election shares MAY qualify, but it’s complicated. If QSBS is on your radar, don’t elect S-corp.

#Pitfall 2: Disqualifying redemptions

If the company buys back stock from anyone (including employees who leave) during the 1-year period before OR 1-year period after issuance, that redemption can disqualify the NEW stock from QSBS treatment. Founders need to coordinate buyback timing with cap-table events.

#Pitfall 3: Crossing the gross-asset threshold

If your company’s gross assets exceed $75M (post-OBBBA) at any point — including immediately after a financing round — new stock issuances stop qualifying. Existing QSBS stays QSBS (the threshold is tested at issuance, not at exit), but new issuances after that point don’t qualify.

#Pitfall 4: Wrong type of business

The “qualified trade or business” exclusion is broad. Service businesses where “the principal asset is the reputation or skill of one or more of its employees” generally DON’T qualify — health, law, accounting, consulting, financial services, performing arts, athletics. SaaS and most software companies DO qualify because the principal asset is the code/product, not specific employee reputation.

#Pitfall 5: Stacking via gifting

You can multiply the per-issuer limit by gifting stock to family members. Each donee gets their own $15M cap. Done right, a founder can effectively exclude $30M, $45M, or more through careful planning with a tax-aware estate attorney. Done wrong, the IRS can challenge as a step-transaction. This needs sophisticated planning.

#Section 1202(h) reinvestment — the rarely-used escape valve

If you need to sell QSBS before hitting the holding-period threshold, §1202(h) lets you roll the proceeds into other QSBS within 60 days. The original holding period tacks onto the new stock.

This is rarely used because most founders selling early aren’t planning to immediately invest in another qualified small business. But for repeat founders + early-stage angels, it’s a real tool.

#Common questions

Does my company qualify for QSBS? Most C-corp operating businesses do, as long as gross assets are under the threshold. Exclusions are listed in §1202(e)(3): services in health, law, finance, accounting, consulting, performing arts, athletics, and a few others. SaaS, e-commerce, manufacturing, biotech, hardware, fintech all generally qualify.

Can I get QSBS treatment on stock I got from converting a SAFE? Yes — the conversion is considered “original issuance” for QSBS purposes. Same for convertible notes. Critical: the holding period starts at conversion, not at the SAFE/note origination.

What about RSUs? RSUs don’t qualify for QSBS because there’s no “purchase” of stock — the shares are delivered as compensation. However, ISOs and NSOs CAN qualify if exercised before the company crosses the gross-asset threshold and held for the required period.

Do all 50 states conform to §1202? No. State conformity varies widely. California does NOT conform to §1202 — California taxes QSBS gain at full state rates. Texas has no state income tax so federal-only matters. New York generally conforms but check specifics. State-level analysis matters for high-income founders.

Can I use QSBS more than once? Yes. The $15M cap is per-issuer, not per-taxpayer lifetime. You can stack multiple companies’ QSBS exclusions across your career. Many serial founders end up using QSBS 2-5 times.

What if I die holding QSBS? QSBS treatment passes to your heirs at full step-up in basis, but the QSBS character is generally preserved if the inheriting party meets the other requirements. This is one of the few cases where dying with appreciated stock is actually tax-favorable (basis step-up + QSBS treatment).

What’s the “10× basis” alternative? If 10× your basis exceeds $15M, you get the bigger number. For most founders this won’t apply (basis is tiny). But for founders who put serious capital in (say $5M founder investment), 10× = $50M. That’s a much bigger exclusion than the $15M cap.

Can I gift QSBS to a trust to multiply the cap? Yes — irrevocable trusts can each get their own $15M cap. This is a sophisticated estate-planning strategy worth $5M-$20M+ in tax savings for high-net-worth founders pre-exit. Needs careful structuring with a tax-aware estate attorney.

Does QSBS apply to ESPP shares? Generally no — ESPP shares are typically purchased at a discount to FMV, which complicates the original issuance requirement. Some narrow ESPP structures might qualify; needs specific analysis.

When should I think about QSBS planning? Three trigger moments:

1. Pre-incorporation — the C-corp-vs-S-corp decision is QSBS-determinative
2. Pre-Series-B — when gross assets are approaching the threshold ($75M post-OBBBA)
3. 18-24 months pre-exit — to evaluate trust/gifting strategies that multiply the cap
