QSBS Basics & Overview: Understanding Qualified Small Business Stock

Qualified Small Business Stock (QSBS) represents a significant tax advantage for investors in eligible small businesses. As delineated in Internal Revenue Code Section 1202, taxpayers may exclude a considerable portion—or in some cases, all—of the capital gains realized from the disposition of QSBS, contingent upon fulfilling specific criteria.

This page offers a detailed exploration of QSBS, including its definition, operational mechanics, essential eligibility requisites, and the tax benefits accessible to qualifying investors.

What is Qualified Small Business Stock (QSBS)?

Qualified Small Business Stock (QSBS) pertains to stock issued by a qualified small business that adheres to precise statutory mandates delineated in IRC Section 1202. Enacted in 1993 with the Revenue Reconciliation Act, the QSBS provisions were designed to stimulate investments into small businesses, fostering economic growth and innovation.

Statutory Definition

Section 1202(c) meticulously defines "qualified small business stock" as stock in a C corporation that meets the following criteria:

• The stock must be originally issued after August 10, 1993, the enactment date of the Revenue Reconciliation Act of 1993 [IRC §1202(c)(1)].
• It should be issued by a corporation that qualifies as a "qualified small business" at the time of issuance [IRC §1202(c)(1)(A)].
• The stock must be acquired by the taxpayer at its original issue (directly or through an underwriter) in exchange for money, other property (excluding stock), or as compensation for services provided to the corporation (excluding services performed as an underwriter) [IRC §1202(c)(1)(B)].

It is crucial to note that only stock acquired at original issue qualifies as QSBS. Stock purchased on the secondary market does not qualify, regardless of whether the issuing corporation meets the other qualifications of a qualified small business.

The Tax Benefit: Capital Gains Exclusion

The primary advantage of investing in QSBS lies in the potential to exclude capital gains from federal income tax, which varies based on the acquisition date and the duration the stock is held.

Exclusion Percentages

The exclusion benefits are tiered based on the stock's acquisition timing and holding period:

• For Stock Acquired on or Before the "Applicable Date" (Currently July 4, 2025):

  • A 50% exclusion is available if the stock is held for more than five years [IRC §1202(a)(1)(A)].

• For Stock Acquired After the "Applicable Date":

  • A 50% exclusion is available if held for at least three years but less than four years.
  • A 75% exclusion if held for at least four years but less than five years.
  • A 100% exclusion if held for five years or more [IRC §1202(a)(1)(B), (a)(5)].

Historical Exclusion Percentages

• A 75% exclusion was applicable for stock acquired between February 18, 2009, and September 27, 2010, if held for more than five years [IRC §1202(a)(3)].
• For stock acquired after September 27, 2010, and on or before the applicable date, a 100% exclusion is available if held for more than five years [IRC §1202(a)(4)].

Per-Issuer Limitations

The exclusion also adheres to per-issuer dollar constraints:

• For Stock Acquired on or Before the Applicable Date:

  • The exclusion is limited to $10 million or 10 times the taxpayer's adjusted basis in the QSBS, whichever is greater, per issuer [IRC §1202(b)(1), (b)(4)(A)].

• For Stock Acquired After the Applicable Date:

  • The limit rises to $15 million or 10 times the taxpayer's adjusted basis in the QSBS, whichever is greater, per issuer [IRC §1202(b)(1), (b)(4)(B)].
  • This amount will adjust for inflation starting in 2027 [IRC §1202(b)(5)].

These limits are applied on a per-issuer basis, allowing a taxpayer to potentially exclude gains from multiple different QSBS issuers, each subject to its separate limit.

Key Eligibility Requirements

To qualify for QSBS tax benefits, both the issuing corporation and the manner in which the stock is acquired must meet stringent requirements:

1. Qualified Small Business Requirements

The issuing entity must be a domestic C corporation throughout the relevant period, as other business structures such as S corporations, partnerships, and LLCs do not qualify [IRC §1202(e)(4)]. Moreover, the corporation's aggregate gross assets must not exceed $75 million at any point from August 10, 1993, up to and including the time of stock issuance [IRC §1202(d)(1)(A), (d)(1)(B)].

The active business requirement mandates that at least 80% of the corporation's assets (by value) be employed directly in the active conduct of one or more qualified trades or businesses [IRC §1202(e)(1)(A)]. Furthermore, the corporation must not engage in certain excluded industries such as professional services, financial services, farming, natural resource extraction, or hospitality [IRC §1202(e)(3)].

2. Stock Acquisition Requirements

The stock must be acquired directly from the corporation or through an underwriter and paid for with money or other property, not including stock, or as compensation for services [IRC §1202(c)(1)(B)].

3. Holding Period Requirements

To qualify for the exclusion, the stock must be held for more than five years if acquired on or before the applicable date [IRC §1202(a)(1)(A)]. For stock acquired after the applicable date, a minimum of three years of holding is required, with the exclusion percentage increasing based on the length of the holding period up to five years [IRC §1202(a)(1)(B), (a)(5)].

4. Taxpayer Eligibility

The Section 1202 exclusion is available only to non-corporate taxpayers, including individuals, trusts, estates, and certain pass-through entities [IRC §1202(a)(1)]. C corporations are not eligible to claim this benefit.

Special Rules and Exceptions

Redemption Restrictions

For stock to qualify as QSBS, the issuing corporation must not engage in certain redemptions that could signify a return of capital to investors rather than an investment in the business's growth and operations [IRC §1202(c)(3)(A), (c)(3)(B)]. These restrictions are detailed further in Reg. 1.1202-2, which includes rules on permissible redemptions and de minimis exceptions.

Pass-Through Entity Treatment

Specific rules under Section 1202(g) accommodate QSBS holdings through partnerships, S corporations, regulated investment companies, and common trust funds. These provisions allow gains from the sale of QSBS held by these entities to flow through to their owners, maintaining eligibility for the exclusion if the owner held an interest in the entity at the time the QSBS was acquired and continuously until its disposition [IRC §1202(g)].

Partners in partnerships holding QSBS should particularly note the impact of capital interest limitations under Section 1045 regulations, which can influence rollover benefits. This aspect is discussed in more detail on related pages.

Transfers and Conversions

Transfers by gift, at death, and certain corporate reorganizations are addressed under Section 1202(h), which provides for the preservation of QSBS status under these circumstances, allowing the continuity of tax benefits across generational transfers and during some business restructuring activities.

Relationship to Section 1045 Rollovers

Section 1045 complements Section 1202 by permitting taxpayers to defer gains from the sale of QSBS if they reinvest the proceeds into new QSBS within a 60-day window. Both sections share a consistent definition of "qualified small business stock," facilitating a cohesive regulatory framework [IRC §1045(b)(1)].

Recent Legislative Changes

The "applicable date" of July 4, 2025, marks a significant juncture in QSBS regulation, introduced by recent legislation (Pub. L. 119-21). This legislation not only adjusted the gross asset threshold and per-issuer exclusion limits but also introduced the nuanced tiered exclusion percentages based on holding periods for stock acquired post-applicable date.

Key Takeaways

• QSBS offers substantial tax savings: Investors can exclude up to 100% of capital gains, subject to per-issuer limits.
• Adherence to eligibility criteria is mandatory: Investors must ensure compliance with detailed corporate, asset, business, and acquisition requirements.
• Acquisition at original issuance is crucial: Secondary market purchases do not qualify.
• Duration of ownership is critical: The holding period significantly affects eligibility, requiring a minimum of 3-5 years depending on the acquisition date.
• Limits are enforced per issuer: Each issuer's limit on exclusion must be considered separately.
• Proactive planning is essential: Investors should confirm QSBS eligibility at the time of investment and diligently maintain necessary documentation.
