QSBS Calculator - Qualified Small Business Stock Tax Exclusion

Maximize your startup exit with Section 1202 QSBS tax exclusion. Calculate potential tax savings up to $10 million on qualified small business stock sales with comprehensive qualification analysis.

Understanding QSBS (Qualified Small Business Stock)

Section 1202 of the Internal Revenue Code provides one of the most powerful tax benefits available to startup founders and early employees - the ability to exclude up to $10 million (or 10x basis) of capital gains from federal taxation when selling qualified small business stock.

The QSBS Advantage

Massive Tax Savings Potential

• Up to $10 million exclusion per taxpayer, per issuer
• 100% federal tax exclusion on qualified gains
• No AMT implications unlike some other preferences
• Estate planning benefits through gifting strategies

Why QSBS Matters for Startups

• Startup founders: Protect gains from company sales or IPOs
• Early employees: Maximize value from stock options and grants
• Angel investors: Tax-efficient exits from successful investments
• Family offices: Multiply exclusions across family members

QSBS Qualification Requirements

The Five Critical Tests

1. Qualified Small Business Test

Company Requirements at Stock Issuance:

• Gross assets ≤ $50 million when stock was issued
• Gross assets ≤ $50 million immediately after stock issuance
• C Corporation (not S Corp, LLC, or partnership)
• Domestic corporation organized in the United States

2. Active Business Test

Qualified Business Activities (80% Rule):

• 80% of assets used in active conduct of qualified business
• Qualified businesses: Most operating businesses
• Excluded businesses: Banking, insurance, financing, investing, brokerage, consulting, engineering, architecture, law, medicine, accounting, hospitality, farming, mineral extraction

3. Original Issuance Test

Stock Acquisition Requirements:

• Original issuance directly from the corporation
• Cash or property exchange (not services)
• Not secondary market purchases
• Option exercises qualify if options granted for original issuance

4. Five-Year Holding Period Test

Timing Requirements:

• Minimum 5 years from acquisition to sale
• Continuous holding throughout the period
• Tacking allowed in certain reorganizations
• Gift recipients can tack donor's holding period

5. Ownership Limitation Test

Redemption Rules:

• No significant redemptions during 4-year testing period
• Complex attribution rules for family and entities
• Safe harbors for de minimis redemptions
• Professional guidance recommended for this test

QSBS Exclusion Limits

Per-Issuer Limits

The exclusion is limited to the greater of:

• $10 million, or
• 10 times the taxpayer's basis in the stock

Basis Multiplication Benefits

• Low basis stock: Dramatically amplifies the exclusion
• Founder shares: Often have minimal basis, maximizing 10x rule
• Early employee options: Low exercise prices create favorable basis

Lifetime Limits

• $10 million per taxpayer for single filers
• $20 million for married couples filing jointly (each spouse gets $10M)
• Separate tracking required for each issuing corporation
• No limit on number of companies that can qualify

Stacking Strategies

Family Multiplication:

• Gift QSBS to children: Each child gets their own $10M limit
• Spousal gifts: Transfer between spouses for optimal timing
• Trust strategies: Grantor trusts can multiply exclusions
• Generation-skipping: Benefits extend to grandchildren
