What Is the QSBS Exclusion in 2026?
Quick Answer: The QSBS exclusion lets you exclude capital gains on qualified small business stock. For 2026, the cap is $15 million or 10x basis.
The Qualified Small Business Stock (QSBS) exclusion is a federal tax benefit under Internal Revenue Code Section 1202. It allows eligible shareholders to exclude a large portion of their capital gains when they sell qualifying stock. Congress first introduced this provision in 1993 to encourage investment in small, early-stage companies. Since then, lawmakers have expanded it several times.
In 2025, the One Big Beautiful Bill Act (OBBBA) made major changes. As a result, the 2026 rules are far more generous than before. You can review the underlying statute directly at the Legal Information Institute Section 1202 text. This is why proactive tax strategy planning for founders now delivers even bigger savings.
Why the 2026 Changes Matter
Previously, the exclusion cap was limited to $10 million or 10x basis. However, OBBBA increased that cap to $15 million for stock issued after July 4, 2025. Furthermore, both dollar limits will be indexed for inflation starting in 2027. Consequently, founders selling qualifying stock in 2026 can shield significantly more gain from federal tax.
Pro Tip: Track your original stock issuance date carefully. Post-July 4, 2025 stock unlocks the new tiered exclusion benefits.
Who Benefits Most From QSBS
Startup founders, early employees, and angel investors gain the most. In addition, venture capital investors and high-net-worth individuals seeking advanced strategies use QSBS to reduce exit taxes. Moreover, the benefit stacks per issuing company. Therefore, investors holding stock in multiple qualifying companies can multiply their exclusions.
How Do You Deduct the QSBS Exclusion?
Quick Answer: You report the sale on Form 8949 and Schedule D. Then you enter the excluded gain with code Q.
Learning how to deduct QSBS exclusion starts with proper reporting. First, you report the stock sale on IRS Form 8949. Next, you carry the totals to Schedule D of your Form 1040. Importantly, you enter the exclusion amount as a negative adjustment using code “Q” in column (f). You can review current instructions on the IRS Schedule D official page.
Step-by-Step Reporting Process
Follow these steps to claim the exclusion accurately:
- Confirm your stock meets all Section 1202 requirements.
- Report the full sale proceeds on Form 8949.
- Enter the excluded gain with code Q in column (f).
- Transfer totals to Schedule D and Form 1040.
- Keep documentation proving your holding period and basis.
Calculating Your Exclusion Amount
Consider a founder who invested $500,000 in qualifying stock. She sells five years later for $10.5 million. Her total gain equals $10 million. Because 10x her $500,000 basis equals $5 million, but the fixed cap is higher, she uses the $15 million cap. Therefore, her entire $10 million gain qualifies for exclusion. Consequently, she owes zero federal capital gains tax on the sale.
Did You Know? The exclusion cap applies per issuer. As a result, separate investments can each claim their own cap.
Because the rules are complex, many founders rely on personalized tax advisory support to file correctly. In addition, working with Tax Strategists in Delaware helps founders coordinate federal and state treatment before an exit.
How Long Must You Hold QSBS in 2026?
Quick Answer: For stock issued after July 4, 2025, hold three years for 50%, four for 75%, and five for 100%.
The holding period rules changed dramatically under OBBBA. Previously, you needed a full five years to claim any exclusion. However, stock issued after July 4, 2025 now uses a tiered system. Therefore, shorter holds still deliver partial benefits. This flexibility helps founders who exit earlier than planned.
The New Tiered Holding Period Table
| Holding Period | Exclusion Percentage | Applies To |
|---|---|---|
| 3 years | 50% | Stock issued after July 4, 2025 |
| 4 years | 75% | Stock issued after July 4, 2025 |
| 5 years | 100% | Stock issued after July 4, 2025 |
Old Rules vs New Rules
Stock issued on or before July 4, 2025 still follows the old five-year, all-or-nothing rule. In contrast, newer stock benefits from the tiered approach. This table compares the two regimes.
| Feature | Pre-July 5, 2025 | Post-July 4, 2025 |
|---|---|---|
| Exclusion cap | $10M or 10x basis | $15M or 10x basis |
| Holding period | 5 years for 100% | Tiered 3/4/5 years |
| Gross asset limit | $50 million | $75 million |
Pro Tip: If your exit approaches year five, waiting a few months may unlock full exclusion.
Does S-Corp or LLC Stock Qualify for the QSBS Exclusion?
Free Tax Write-Off FinderQuick Answer: No. Only original-issue C-corporation stock qualifies. S-Corp and LLC interests do not.
This is one of the most common QSBS mistakes. Only C-corporation stock qualifies for the Section 1202 exclusion. Therefore, S-Corps, LLCs, and partnerships do not produce QSBS directly. However, an LLC can convert to a C-corporation before issuing qualifying stock. Consequently, entity choice becomes a critical planning decision for founders.
Why Entity Structure Drives QSBS Eligibility
Many startups begin as LLCs for flexibility. However, that structure blocks QSBS treatment. As a result, founders often convert to a C-corporation before a major fundraising round. In addition, the stock must be issued at original issue, meaning directly from the company. Proper business entity structuring guidance prevents costly eligibility errors.

Comparing a Standard Sale to a QSBS Strategy
Consider a $5 million capital gain under the 75% exclusion tier. The savings are substantial, as this comparison shows.
| Metric | Standard Sale (23.8%) | QSBS 75% Exclusion |
|---|---|---|
| Total capital gain | $5,000,000 | $5,000,000 |
| Federal exclusion | $0 | $3,750,000 |
| Taxable amount | $5,000,000 | $1,250,000 |
| Federal tax due | $1,190,000 | $350,000 |
This single strategy saves $840,000 in federal tax. For guidance on business structures, review the SBA business structure guide.
What Are the QSBS Qualification Tests?
Quick Answer: The company must be a C-corp, meet the $75 million gross asset test, and run an active qualified business.
Several tests must be satisfied for stock to qualify. First, the issuer must be a domestic C-corporation. Second, the company’s gross assets must not exceed $75 million when the stock is issued. Third, at least 80% of assets must support an active qualified trade or business. Furthermore, you must acquire the stock at original issue.
The Gross Asset Test Explained
OBBBA raised the gross asset threshold to $75 million. Previously, the limit was $50 million. Moreover, this amount will be indexed for inflation for tax years beginning after 2026. Therefore, more mid-sized companies now qualify. This expansion benefits both founders and later-stage investors. As a result, business owners planning an exit should confirm asset levels before each stock issuance.
Businesses That Do Not Qualify
Certain industries are excluded from QSBS treatment. Consequently, you cannot use the exclusion for these fields:
- Health, law, accounting, and consulting services.
- Financial services, banking, and insurance.
- Farming and certain natural resource operations.
- Hospitality businesses like hotels and restaurants.
Pro Tip: Document your active business use each year. Audit-proof records protect your exclusion claim.
Because state conformity varies, some states tax QSBS gains despite the federal exclusion. Therefore, confirm your state’s stance early. For research, the Tax Foundation policy resources track state conformity trends. Meanwhile, real estate investors diversifying into startups should review both federal and state impacts.
Uncle Kam in Action: How a SaaS Founder Saved $2.1 Million
Client Snapshot: Maya, a 38-year-old software founder, built a B2B SaaS company. She originally formed it as an LLC in Delaware.
Financial Profile: Her company reached a $12 million valuation in 2026. She held a $600,000 adjusted basis in her founder shares.
The Challenge: Maya planned a partial exit. However, her LLC structure blocked QSBS eligibility entirely. As a result, she faced a large federal capital gains bill. Furthermore, she did not know how to deduct QSBS exclusion or whether she could still qualify.
The Uncle Kam Solution: Our team converted her LLC to a C-corporation before her next funding round. Consequently, newly issued stock qualified as QSBS under Section 1202. In addition, we confirmed the company met the $75 million gross asset test. Then we mapped her holding period against the new tiered rules. Because she planned to hold beyond five years, she targeted the full 100% exclusion tier. Moreover, we coordinated Form 8949 and Schedule D reporting to document everything correctly.
The Results: When Maya sells her qualifying shares after five years, she projects excluding roughly $8.8 million in gain. Therefore, she avoids approximately $2.1 million in federal capital gains tax. Her investment with Uncle Kam totaled $18,000 for the planning engagement. As a result, her first-year projected ROI exceeds 100x on the strategy. See more outcomes on our client results and case studies page. Ultimately, early planning transformed a huge tax bill into a near-zero federal outcome.
