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.

Definition: A C-corporation is a business entity taxed separately from its owners under Subchapter C of the Internal Revenue Code, facing corporate income tax at the entity level.

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
⚠️ Warning: Converting from C-corporation to S-corporation status disqualifies previously issued QSBS. This conversion triggers immediate loss of Section 1202 benefits.

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)
💡 Key Insight: A Delaware C-corporation owned entirely by foreign investors still qualifies for QSBS. The corporation's formation location matters, not shareholder citizenship.

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.

Definition: Active conduct means using assets directly in business operations to produce goods, perform services, or generate revenue from qualified business activities.

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
⚠️ Warning: Holding more than 20% of assets in passive investments or excessive cash reserves disqualifies stock from QSBS treatment, even if the company otherwise qualifies.

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:

  1. Two-year designation - Management designates funds for specific business purposes within two years
  2. Reasonable amounts - Working capital levels align with normal business plans
  3. 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:

  1. Determine total asset fair market value (FMV) at measurement date
  2. Identify assets in active business use (operations, inventory, equipment)
  3. Calculate active asset percentage (Active FMV ÷ Total FMV)
  4. Compare to 80% threshold (must exceed to maintain qualification)
📋 Quick Summary: Calculate asset utilization quarterly to ensure ongoing compliance. Values below 80% active use disqualify QSBS prospectively.

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.

Definition: Gross assets means the total value of all corporate assets without reduction for liabilities, measured on a tax basis (not GAAP book value or fair market value).

Critical Measurement Points

The $50 million cap applies at two specific times:

  1. Immediately before stock issuance - Pre-money valuation and existing assets
  2. 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)
⚠️ Warning: Exceeding $50 million immediately after issuance disqualifies that entire stock issuance permanently. Previous issuances below the threshold remain qualified.

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
💡 Key Insight: Technology startups with internally developed software often have low tax basis despite high fair market value, making QSBS qualification easier.

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:

  1. Two years before issuance - Significant redemptions may disqualify new issuances
  2. Two years after issuance - Redemptions may disqualify recently issued stock
  3. Attribution period - Four-year total window for redemption analysis
⚠️ Warning: Repurchasing more than 5% of stock value within two years before or after an issuance can disqualify that issuance under de minimis exceptions.

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:

  1. 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
  2. Financial services (Section 1202(e)(3)(B))

    • Banking and lending
    • Insurance companies
    • Financing operations
    • Investment management
    • Securities and commodities brokerage
  3. Farming businesses (Section 1202(e)(3)(C))

    • Agricultural production
    • Commercial farming operations
    • Livestock raising
  4. Natural resource extraction (Section 1202(e)(3)(D))

    • Oil and gas production
    • Mining operations
    • Timber extraction
    • Other natural resource businesses
  5. Hospitality (Section 1202(e)(3)(E))

    • Hotels and motels
    • Restaurants and food service
Definition: Professional services means businesses where the principal asset is the reputation or skill of one or more employees, with services provided directly by employees.

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
💡 Key Insight: Companies selling software or technology products to excluded industries generally qualify. The exclusion applies to performing the restricted services, not serving those industries.

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
📋 Quick Summary: If the business cannot scale without hiring proportionally more professionals, it likely provides excluded services rather than qualified products.

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.

Definition: Original issuance means stock received directly from the corporation in exchange for money, property, or services, not purchased from existing shareholders.

Qualified acquisition methods:

  1. Cash investment - Direct purchase of newly issued shares from the company
  2. Property transfer - Contributing assets in exchange for stock
  3. Service compensation - Receiving shares for services to the corporation
  4. Conversion of qualified instruments - Convertible notes or SAFEs issued when company qualified

Non-qualified acquisition methods:

  1. Secondary purchases - Buying shares from existing shareholders
  2. Inheritance - Receiving stock from deceased shareholders
  3. Gift transfers - Stock received as gifts from current holders
  4. Non-qualified conversions - Converting debt issued after company exceeded thresholds
⚠️ Warning: Purchasing even one share from an existing shareholder on the secondary market disqualifies those shares permanently from QSBS treatment.

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
💡 Key Insight: Early-stage investors using SAFEs or convertible notes protect QSBS eligibility even as companies grow beyond $50 million before equity conversion.

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
Definition: The holding period is the continuous timespan an investor owns qualified small business stock, measured from original issuance until sale or exchange.

Holding Period Tracking

Key dates to document:

  1. Original issuance date - Stock certificate or subscription agreement date
  2. Vesting schedule completion - Restricted stock becomes unrestricted
  3. Conversion dates - If converting from notes, SAFEs, or preferred stock
  4. Transfer dates - Any ownership changes within family or trusts
  5. Anticipated sale date - Target exit timing to meet five-year requirement
📋 Quick Summary: Mark your calendar for five years plus one day from stock issuance to begin tax-free sale eligibility planning.

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)
⚠️ Warning: Waiting even one day short of five full years costs the entire QSBS exclusion. Verify exact dates before executing sales.

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:

  1. Asset utilization review (80% active business test)

    • Calculate total asset fair market value
    • Identify passive vs. active business assets
    • Document compliance or corrective actions
  2. Gross asset tracking (aggregate issuance monitoring)

    • Track cumulative issuances against $50 million threshold
    • Plan timing for future fundraising rounds
    • Model redemption impacts on qualification
  3. 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
  4. Corporate status confirmation (C-corporation maintenance)

    • Verify continued C-corporation tax status
    • Confirm no S-corporation election filed
    • Document entity classification continuity
💡 Key Insight: Implement quarterly QSBS compliance reviews with finance and tax teams to identify and correct qualification threats before they disqualify stock.

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:

  1. 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
  2. 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
  3. 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
  4. 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
⚠️ Warning: Disqualification events don't invalidate holding periods already completed. Stock qualifying for five years before disqualification retains QSBS benefits for that period.

Remediation Strategies

When compliance issues arise:

Asset utilization failures:

  1. Immediate deployment - Invest passive cash in active business assets within 60-90 days
  2. Working capital documentation - Retroactively document business plans for safe harbor
  3. Asset disposition - Sell or distribute passive investments to shareholders

Industry restriction concerns:

  1. Activity separation - Transfer excluded services to separate subsidiary
  2. Revenue reallocation - Price excluded services at cost to minimize gross receipts
  3. Business model pivot - Transition from services to product delivery

Structural issues:

  1. Election reversal timing - Coordinate S-corp elections with investor exits
  2. Redemption planning - Space share repurchases outside attribution windows
  3. 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
📋 Quick Summary: Most compliance failures can be remedied prospectively but don't cure past periods. Proactive monitoring prevents disqualification rather than requiring reactive fixes.

Professional Tax Guidance

QSBS qualification complexity requires specialized tax advisor involvement for companies issuing stock and investors claiming benefits. The interplay of multiple requirements and subjective tests necessitates professional analysis.

When to engage QSBS specialists:

  • Company formation - Structure entity correctly from inception
  • Each fundraising round - Verify $50 million test compliance before issuance
  • Annual compliance reviews - Assess ongoing qualification maintenance
  • Business model changes - Evaluate impacts of new activities or acquisitions
  • Shareholder exit planning - Confirm qualification and optimize tax benefits

Investor tax planning services:

  • Original issuance verification and documentation
  • Holding period tracking and calendar management
  • Exit timing optimization around five-year anniversaries
  • QSBS gain calculation and exclusion claiming
  • State tax treatment analysis (varies significantly by state)
💡 Key Insight: Tax advisor fees typically represent 0.1-0.5% of potential QSBS tax savings, making professional guidance highly cost-effective for significant equity positions.

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.
