Qualified Small Business Stock (QSBS) requirements determine whether investors can exclude up to $10 million or 10 times their basis in capital gains from federal taxation. Section 1202 establishes strict criteria spanning corporate structure, business operations, asset thresholds, and holding periods that companies and shareholders must satisfy to qualify for these substantial tax benefits.
Understanding QSBS requirements ensures investors structure their investments correctly and companies maintain compliance throughout their growth trajectory. This guide covers all qualification criteria under IRC Section 1202.
Corporate Structure and Formation
The foundation of QSBS qualification begins with proper corporate structure. Companies must meet specific entity formation and tax classification requirements from the moment stock is originally issued.
C-Corporation Requirement
Only C-corporations issue stock eligible for QSBS treatment under Section 1202. S-corporations, partnerships, limited liability companies (LLCs), and sole proprietorships categorically cannot issue qualified small business stock.
The C-corporation requirement must exist at the time of stock issuance. Converting from an LLC or S-corporation to C-corporation status before issuing new shares enables QSBS qualification for those newly issued shares only.
Entity Classification Timing
| Scenario | QSBS Eligible? | Explanation |
|---|---|---|
| C-corp at issuance | ✓ Yes | Meets classification requirement |
| LLC converts to C-corp, then issues | ✓ Yes | New shares after conversion qualify |
| S-corp converts to C-corp | ✓ Yes | Post-conversion shares only |
| C-corp converts to S-corp | ✗ No | Existing QSBS disqualified |
Stock issued while operating as an S-corporation never qualifies, even if the company later converts to C-corporation status. The classification at the original issuance date controls qualification permanently.
Domestic Business Entity
Section 1202 requires corporations to be domestic entities organized under federal or state law within the United States. Foreign corporations incorporated outside U.S. jurisdiction cannot issue QSBS regardless of where they conduct business operations.
Domestic Entity Criteria
Qualifying formations:
- Incorporated in any U.S. state (Delaware, Nevada, Wyoming, etc.)
- Organized under federal law (rare for operating businesses)
- U.S. territory incorporation (Puerto Rico, U.S. Virgin Islands)
Non-qualifying formations:
- Foreign corporations incorporated abroad
- Canadian, U.K., or other non-U.S. entities
- Subsidiaries of foreign parent companies (complex rules apply)
Foreign individuals and entities can hold QSBS and potentially claim Section 1202 exclusions, though state tax treatment varies and international tax treaties may affect benefits. The domestic entity requirement applies exclusively to the issuing corporation's formation jurisdiction.
Business Operations Requirements
Beyond corporate structure, companies must demonstrate genuine active business operations. Section 1202 targets operating companies creating jobs and economic value, not passive investment vehicles.
Active Business Test
The 80% active business use test requires companies to deploy at least 80% of asset value in the active conduct of qualified trade or business activities. This threshold applies throughout the shareholder's entire holding period.
Qualified active uses include:
- Manufacturing equipment and facilities
- Inventory for sale to customers
- Office space for employee operations
- Technology and software for service delivery
- Vehicles for business transportation
- Working capital for operational expenses
Non-qualified passive uses include:
- Real estate held for investment appreciation
- Stock portfolios or securities investments
- Excess cash beyond reasonable working capital needs
- Assets leased to unrelated parties
- Passive royalty-generating intellectual property
Working Capital Safe Harbors
The IRS provides safe harbor rules for working capital that would otherwise appear passive. Companies may hold cash and short-term investments as working capital if:
- Two-year designation - Management designates funds for specific business purposes within two years
- Reasonable amounts - Working capital levels align with normal business plans
- Progress toward deployment - Company demonstrates ongoing progress using funds as planned
| Working Capital Amount | Safe Harbor Status | Requirements |
|---|---|---|
| Under $500,000 | Generally acceptable | Basic business plan documentation |
| $500,000 - $2,000,000 | Requires justification | Detailed deployment plans within 24 months |
| Over $2,000,000 | Enhanced scrutiny | Quarterly milestone tracking required |
Companies should document working capital deployment plans contemporaneously with fundraising to support safe harbor qualification.
Asset Utilization Standards
Asset utilization standards prevent companies from converting to passive investment vehicles after issuing QSBS. The substantially all test requires continuous active business operations throughout the holding period.
Substantially all means 80% or more of asset value by fair market value, not book value. This calculation includes all corporate assets on a consolidated basis.
Asset Calculation Methodology
Step-by-step calculation:
- Determine total asset fair market value (FMV) at measurement date
- Identify assets in active business use (operations, inventory, equipment)
- Calculate active asset percentage (Active FMV ÷ Total FMV)
- Compare to 80% threshold (must exceed to maintain qualification)
Example calculation:
- Total assets (FMV): $10,000,000
- Active business assets: $8,200,000 (82%)
- Passive investments: $1,800,000 (18%)
- Result: Meets 80% threshold, QSBS qualified
If passive investments increased to $2,100,000 (21%), the company would fall below the 80% threshold and fail the active business test.
Asset and Size Limitations
Section 1202 targets "small business" investment by imposing strict asset caps. Companies must remain below gross asset thresholds both before and immediately after stock issuance.
Gross Assets Cap
The $50 million gross asset test serves as the bright-line qualification threshold. Companies with gross assets exceeding $50 million at the time of stock issuance cannot issue QSBS under any circumstances.
Critical Measurement Points
The $50 million cap applies at two specific times:
- Immediately before stock issuance - Pre-money valuation and existing assets
- Immediately after stock issuance - Post-money valuation including new capital
Both measurements must fall at or below $50 million for the newly issued shares to qualify as QSBS.
| Measurement Point | Gross Assets | Investment Amount | Post-Money Assets | QSBS Qualified? |
|---|---|---|---|---|
| Pre-issuance | $45 million | $3 million | $48 million | ✓ Yes |
| Pre-issuance | $48 million | $5 million | $53 million | ✗ No |
| Pre-issuance | $50 million | $500,000 | $50.5 million | ✗ No |
| Pre-issuance | $49 million | $1 million | $50 million | ✓ Yes (at limit) |
Companies approaching the threshold should:
- Calculate gross assets before each fundraising round
- Consider splitting large rounds into tranches
- Time equity issuances strategically around asset fluctuations
- Use convertible debt to delay equity issuance
Timing of Asset Measurement
Asset measurement timing critically affects QSBS qualification. The $50 million test applies at the moment of stock issuance, creating planning opportunities and potential traps.
Tax Basis vs. Fair Market Value
Section 1202 uses tax basis (also called adjusted basis) for the gross asset calculation, not fair market value or GAAP book value. This distinction significantly affects technology companies with valuable intangible assets.
Tax basis considerations:
- Purchased assets: Original cost less accumulated depreciation
- Developed software: Generally expensed (zero basis unless capitalized)
- Self-created IP: Development costs expensed (zero basis)
- Cash and marketable securities: Face value equals basis
- Equipment: Cost less accumulated tax depreciation
Example comparison:
| Asset Category | Fair Market Value | Tax Basis | Difference |
|---|---|---|---|
| Developed software platform | $30 million | $0 | $30 million |
| Office equipment | $500,000 | $300,000 | $200,000 |
| Cash and receivables | $5 million | $5 million | $0 |
| Total | $35.5 million | $5.3 million | $30.2 million |
This company qualifies under the $50 million tax basis test despite $35.5 million FMV.
Redemption and Repurchase Impact
Stock redemptions reduce gross assets but create attribution risks. Purchasing shares from existing shareholders within a four-year window may disqualify stock issued to related parties.
The two-year/four-year redemption rules:
- Two years before issuance - Significant redemptions may disqualify new issuances
- Two years after issuance - Redemptions may disqualify recently issued stock
- Attribution period - Four-year total window for redemption analysis
Industry and Business Restrictions
Section 1202 excludes specific industries from QSBS qualification regardless of meeting other requirements. These categorical exclusions prevent tax benefits for businesses Congress deemed inappropriate for incentivization.
Excluded Industries
Categorically excluded businesses include:
Professional services (Section 1202(e)(3)(A))
- Health (doctors, dentists, veterinarians)
- Law (attorneys, legal services)
- Engineering and architecture
- Accounting and actuarial services
- Performing arts (actors, musicians)
- Consulting services
- Athletics (professional sports)
- Brokerage services
Financial services (Section 1202(e)(3)(B))
- Banking and lending
- Insurance companies
- Financing operations
- Investment management
- Securities and commodities brokerage
Farming businesses (Section 1202(e)(3)(C))
- Agricultural production
- Commercial farming operations
- Livestock raising
Natural resource extraction (Section 1202(e)(3)(D))
- Oil and gas production
- Mining operations
- Timber extraction
- Other natural resource businesses
Hospitality (Section 1202(e)(3)(E))
- Hotels and motels
- Restaurants and food service
Gray Area Businesses
Technology-enabled service businesses create classification ambiguity. The IRS applies a facts and circumstances test examining whether the business primarily involves product delivery or personal services.
| Business Type | QSBS Qualification | Analysis |
|---|---|---|
| Healthcare SaaS platform | Likely qualifies | Software product, not medical services |
| Telemedicine service | Likely excluded | Doctors providing health services |
| Legal document automation | Likely qualifies | Technology product vs. legal advice |
| Accounting firm using software | Excluded | Core business is accounting services |
| Restaurant delivery platform | Qualifies | Technology platform, not operating restaurants |
| Boutique hotel chain | Excluded | Operating hotels directly |
De Minimis Exception
The 10% gross receipts test provides limited relief. Companies deriving less than 10% of gross receipts from excluded activities may still qualify if those activities are incidental to qualified business operations.
Example application:
- Primary business: Manufacturing software (qualified)
- Incidental consulting: Implementation services (excluded activity)
- Consulting revenue: 8% of total gross receipts
- Result: De minimis exception applies, full QSBS qualification maintained
Once excluded activities exceed 10% of gross receipts, the entire corporation's stock becomes disqualified prospectively.
Service Business Determination
The reputation or skill test distinguishes product businesses from excluded service businesses. This subjective standard evaluates whether customer value derives primarily from employee expertise or from products and systems.
Reputation or skill factors:
- High indicator of services: Business revolves around named individuals (e.g., "Smith Consulting")
- Product indicator: Scalable delivery without founder involvement
- Service indicator: Customized deliverables requiring professional judgment
- Product indicator: Standardized offerings with automated fulfillment
Comparison examples:
| Business Model | Qualification | Reasoning |
|---|---|---|
| SaaS platform with self-service | Qualifies | Product scales independently |
| Professional services firm | Excluded | Revenue requires professional labor |
| Healthcare AI diagnostic tool | Qualifies | Software product, not medical services |
| Engineering consulting | Excluded | Services require engineer expertise |
| Tax preparation software | Qualifies | Automated product vs. accounting services |
Companies straddling this line should document product characteristics, automation features, and scalability metrics to support QSBS qualification.
Stock Acquisition and Holding
Investors must acquire and hold QSBS properly to claim Section 1202 benefits. Acquisition method, holding duration, and ownership continuity all affect qualification.
Original Issuance Requirement
QSBS qualification requires investors to acquire stock through original issuance directly from the corporation. Secondary market purchases from other shareholders categorically fail this requirement.
Qualified acquisition methods:
- Cash investment - Direct purchase of newly issued shares from the company
- Property transfer - Contributing assets in exchange for stock
- Service compensation - Receiving shares for services to the corporation
- Conversion of qualified instruments - Convertible notes or SAFEs issued when company qualified
Non-qualified acquisition methods:
- Secondary purchases - Buying shares from existing shareholders
- Inheritance - Receiving stock from deceased shareholders
- Gift transfers - Stock received as gifts from current holders
- Non-qualified conversions - Converting debt issued after company exceeded thresholds
Conversion and Exchange Rules
Stock received through qualified conversions or exchanges may maintain QSBS status if the original instrument qualified. Convertible debt and preferred stock conversion follow specific rules.
SAFE and convertible note conversions:
- Issuance date determines qualification - SAFE or note must be issued when company meets QSBS requirements
- Conversion timing irrelevant - Stock qualifies even if company exceeds thresholds at conversion
- Holding period relates back - Five-year holding period starts from original SAFE/note issuance
| Original Instrument | Company Status at Issuance | Converted Stock QSBS? | Holding Period Start |
|---|---|---|---|
| SAFE | Qualified ($40M assets) | ✓ Yes | SAFE issuance date |
| Convertible note | Qualified ($50M assets) | ✓ Yes | Note issuance date |
| SAFE | Disqualified ($60M) | ✗ No | N/A |
| Preferred stock | Qualified at original issue | ✓ Yes | Original issuance date |
Preferred-to-common conversions:
- Preferred stock originally issued as QSBS retains qualification when converted to common
- Holding period includes time held as preferred stock
- Conversion ratios or adjustments don't affect QSBS status
Five-Year Holding Period
The five-year minimum holding period represents the most straightforward QSBS requirement. Investors must hold qualified stock for more than five years from the original issuance date to claim Section 1202 exclusions.
Holding period mechanics:
- Start date: Date of original issuance from corporation
- End date: Must exceed five full years (e.g., issued Jan 15, 2020 → must hold past Jan 15, 2025)
- Continuous holding: Uninterrupted ownership throughout period
- Attribution rules: Certain transfers maintain holding period continuity
Holding Period Tracking
Key dates to document:
- Original issuance date - Stock certificate or subscription agreement date
- Vesting schedule completion - Restricted stock becomes unrestricted
- Conversion dates - If converting from notes, SAFEs, or preferred stock
- Transfer dates - Any ownership changes within family or trusts
- Anticipated sale date - Target exit timing to meet five-year requirement
Tracking example timeline:
- Feb 10, 2020: Investor purchases Series A preferred stock
- Feb 10, 2023: Company Series C triggers automatic conversion to common
- Feb 11, 2025: Five-year holding period satisfied (measured from Feb 10, 2020)
- Eligible: Can sell with QSBS exclusion on or after Feb 11, 2025
The holding period calculation uses the original issuance date, not conversion dates for qualified conversions.
Early Exit Considerations
Selling before completing the five-year holding period permanently forfeits QSBS benefits for those shares. No exceptions exist for hardship, company circumstances, or partial holding period completion.
Early sale consequences:
- Capital gains taxed normally - Federal rates up to 23.8% (20% + 3.8% NIIT)
- State taxes apply - No state tax exclusions for non-qualified sales
- No partial benefits - Holding 4.5 years provides zero QSBS advantage
- Lost opportunity cost - Cannot reclaim benefits if company later fails
| Holding Period | Sale Price | Tax Without QSBS | Tax With QSBS | Benefit Lost |
|---|---|---|---|---|
| 3 years | $5,000,000 | $1,190,000 | $0 | $1,190,000 |
| 4.9 years | $5,000,000 | $1,190,000 | $0 | $1,190,000 |
| 5+ years | $5,000,000 | $1,190,000 | $0 | $0 (qualified) |
Ongoing Compliance Monitoring
QSBS qualification requires continuous compliance throughout the five-year holding period. Companies that initially qualify can lose eligibility through subsequent business changes, asset composition shifts, or structural modifications.
Annual Compliance Checklist
Quarterly monitoring requirements:
Asset utilization review (80% active business test)
- Calculate total asset fair market value
- Identify passive vs. active business assets
- Document compliance or corrective actions
Gross asset tracking (aggregate issuance monitoring)
- Track cumulative issuances against $50 million threshold
- Plan timing for future fundraising rounds
- Model redemption impacts on qualification
Industry activity verification (excluded business screening)
- Review gross receipts by business activity category
- Ensure excluded activities remain below 10% threshold
- Document de minimis exception if applicable
Corporate status confirmation (C-corporation maintenance)
- Verify continued C-corporation tax status
- Confirm no S-corporation election filed
- Document entity classification continuity
Compliance Documentation
Essential records to maintain:
- Stock ledger with original issuance dates and prices
- Quarterly balance sheets showing asset composition
- Revenue breakdown by business activity category
- Corporate formation and tax election documents
- Board resolutions related to structure changes
- Investor communication confirming QSBS intent
Disqualification Events
Specific corporate actions and business changes disqualify previously qualified stock prospectively from the date of change. Understanding disqualification triggers prevents inadvertent loss of tax benefits.
Common disqualification events:
Converting to S-corporation status
- Effect: Immediate QSBS disqualification for all shareholders
- Timing: Disqualification from election effective date
- Mitigation: Delay S-corp election until after shareholders exit
Exceeding 80% active business threshold
- Effect: Prospective disqualification while non-compliant
- Timing: Measured quarterly or at sale date
- Mitigation: Rebalance assets within 90 days, document remediation
Engaging in excluded business activities >10%
- Effect: Disqualifies stock issued while exceeding threshold
- Timing: Annual measurement based on gross receipts
- Mitigation: Spin off excluded activities to separate entity
Significant redemptions within attribution period
- Effect: May disqualify related party issuances
- Timing: Two years before through two years after issuance
- Mitigation: Limit redemptions to less than 5% of outstanding stock
Remediation Strategies
When compliance issues arise:
Asset utilization failures:
- Immediate deployment - Invest passive cash in active business assets within 60-90 days
- Working capital documentation - Retroactively document business plans for safe harbor
- Asset disposition - Sell or distribute passive investments to shareholders
Industry restriction concerns:
- Activity separation - Transfer excluded services to separate subsidiary
- Revenue reallocation - Price excluded services at cost to minimize gross receipts
- Business model pivot - Transition from services to product delivery
Structural issues:
- Election reversal timing - Coordinate S-corp elections with investor exits
- Redemption planning - Space share repurchases outside attribution windows
- Issuance sequencing - Time new issuances when compliance is certain
| Issue Type | Detection Window | Remediation Period | Compliance Restoration |
|---|---|---|---|
| Asset utilization | 90 days | 30-60 days | Prospective only |
| Excluded business | Annual | Before year-end | Following tax year |
| Corporate structure | Immediate | Cannot reverse | New issuances only |
| Redemptions | 4-year window | Before issuance | Delay issuance 2 years |

Frequently Asked Questions
What are the basic requirements for stock to qualify as QSBS?
Stock must meet five core requirements: issued by a domestic C-corporation, acquired at original issuance, company had ≤$50 million gross assets at issuance, used in active qualified business with ≥80% of assets, and held for more than five years.
Can S-corporations issue qualified small business stock?
No. Only C-corporations can issue QSBS. S-corporations categorically cannot issue qualified stock regardless of meeting other requirements. Companies must convert to C-corporation status before issuance for shares to qualify.
How is the $50 million gross asset test calculated?
The test uses tax basis (adjusted basis) of all corporate assets, not fair market value or book value. Measurement occurs immediately before and immediately after stock issuance. Both measurements must not exceed $50 million.
What happens if a company exceeds the $50 million threshold?
Stock issued after exceeding $50 million doesn't qualify as QSBS. However, stock issued before crossing the threshold remains qualified, assuming all other requirements continue to be met throughout the holding period.
Does the five-year holding period include time holding convertible notes?
Yes. When convertible notes or SAFEs convert to QSBS, the holding period includes the time holding the original instrument, provided the note or SAFE was issued when the company met QSBS requirements.
What industries are excluded from QSBS qualification?
Excluded industries include professional services (health, law, accounting, consulting), financial services (banking, insurance, brokerage), farming, natural resource extraction, and hospitality (hotels and restaurants).
Key Takeaway: QSBS requirements span corporate structure, business operations, asset thresholds, industry restrictions, and holding periods. Meeting all requirements simultaneously throughout the five-year holding period qualifies investors for substantial federal capital gains tax exclusions up to $10 million or 10 times basis.
