Internal Revenue Code Section 1202 offers one of the most significant tax benefits available to founders, entrepreneurs and investors in qualifying small businesses. When its requirements are satisfied, Section 1202 can permit a shareholder to exclude a substantial portion, and potentially all, of the federal capital gain realized when Qualified Small Business Stock, commonly referred to as QSBS, is sold.
For a successful business, the tax savings can be enormous. This makes Section 1202 something that should ideally be considered when a business is formed or capitalized, not merely when the owners begin thinking about selling it.
Just as importantly, Section 1202 is not limited to technology startups or venture-capital investments. Many ordinary operating businesses, including general contractors and construction companies, may potentially qualify.
What Is Section 1202?
Section 1202 was enacted to encourage investment in smaller domestic businesses by providing favorable tax treatment to investors willing to put capital at risk and hold their investment for an extended period.
In general, Section 1202 allows a noncorporate taxpayer who owns qualifying stock in a domestic C corporation to exclude some or all of the gain realized when that stock is eventually sold.
Historically, the best-known version of the rule provided a 100% exclusion after the required five-year holding period for qualifying stock acquired after September 27, 2010.
Congress significantly expanded Section 1202 in 2025. For qualifying stock acquired after July 4, 2025, the exclusion is phased in based upon the shareholder’s holding period:
- 3 years: 50% of qualifying gain may be excluded.
- 4 years: 75% of qualifying gain may be excluded.
- 5 years or more: 100% of qualifying gain may be excluded.
The rules applicable to older QSBS depend upon when the stock was acquired, so the date of acquisition remains important.
Basic Qualification Requirements
Several requirements must be satisfied before stock can qualify for Section 1202 treatment.
1. The Company Must Be a Domestic C Corporation
QSBS must be stock of a domestic C corporation.
An LLC taxed as a partnership, a partnership, a sole proprietorship or an S corporation cannot itself issue QSBS.
This makes entity selection particularly important for entrepreneurs creating businesses with substantial growth potential. The immediate tax advantages of operating as an S corporation or partnership should sometimes be weighed against the potentially much larger future benefit available under Section 1202.
2. The Stock Generally Must Be Acquired at Original Issuance
The shareholder generally must acquire the stock directly from the corporation at its original issuance, either in exchange for money, qualifying property, or services provided to the corporation.
Simply buying shares from an existing shareholder ordinarily does not create QSBS.
There are important exceptions and carryover rules, including certain acquisitions by gift, inheritance, conversion or exchange, but the basic principle is that Section 1202 is intended to encourage investment into the qualifying business, rather than purchases of stock from existing owners.
3. The Corporation Must Satisfy the Gross-Assets Test
The corporation must satisfy an aggregate gross-assets limitation when the qualifying stock is issued.
For stock issued after July 4, 2025, the applicable threshold is generally $75 million. For stock issued on or before July 4, 2025, the previous $50 million threshold generally applies.
Importantly, this is often misunderstood as a permanent ceiling on the size of the company. It is not.
The test generally looks at the corporation’s aggregate gross assets before the stock issuance and immediately after the issuance. A company that subsequently becomes worth $100 million, $500 million or even $1 billion does not lose QSBS status merely because it became successful after the qualifying shares were issued.
In fact, that growth is precisely where Section 1202 can become so valuable.
4. The Corporation Must Conduct a Qualified Trade or Business
During substantially all of the shareholder’s applicable holding period, at least 80% of the corporation’s assets, by value, generally must be used in the active conduct of one or more qualified trades or businesses.
This requirement deserves particular attention because there is considerable misunderstanding about what constitutes a “qualified” business.
What Types of Businesses Can Qualify?
Many business owners assume Section 1202 is limited to technology companies, manufacturers, biotech startups or other businesses developing innovative products.
That is not the law.
Section 1202 does not require a company to be a technology company, a venture-backed startup, or even particularly innovative.
More importantly, Section 1202 does not contain a blanket exclusion for service businesses. Instead, Congress specifically identified certain categories of businesses that do not qualify.
This means that a surprisingly wide range of ordinary operating businesses can potentially qualify.
Subject to the other Section 1202 requirements, examples of businesses that may potentially qualify include:
- General contractors and construction companies
- Electrical contractors
- Plumbing companies
- HVAC contractors
- Roofing companies
- Excavation and grading contractors
- Other specialty trade contractors
- Manufacturing companies
- Software and technology companies
- Product development businesses
- Retail businesses
- E-commerce businesses
- Wholesale and distribution companies
- Transportation and logistics companies
- Equipment and machinery businesses
- Staffing and employment businesses
- Telecommunications companies
- Certain marketing and advertising businesses
- Certain property-management and operational service businesses
- Many other operating companies that do not fall within one of the specifically excluded categories.
The fact that a company provides a service does not, standing alone, prevent its stock from qualifying as QSBS.
A General Contractor Is a Good Example
Consider a successful general contractor.
The company employs 75 people, maintains construction equipment, manages multiple projects, supervises subcontractors, maintains bonding and banking relationships, negotiates contracts and has established project-management and operating systems.
It is unquestionably providing services.
But construction is not one of the professional service categories specifically excluded by Section 1202.
The fact that the company employs skilled workers, estimators, project managers and construction professionals does not automatically turn it into an excluded professional-service business.
Accordingly, a properly structured construction company organized and operated as a domestic C corporation may potentially issue QSBS.
The same analysis could apply to an electrical contractor, HVAC company, plumbing company, roofing contractor or other specialty construction company.
This distinction is critical because the phrase “service business” is sometimes used too broadly when discussing Section 1202. The statute does not say that businesses providing services are excluded. It identifies particular categories of businesses that Congress chose to exclude.
Which Businesses Are Specifically Excluded?
Section 1202 excludes businesses involving the performance of services in the fields of:
- Health
- Law
- Engineering
- Architecture
- Accounting
- Actuarial science
- Performing arts
- Consulting
- Athletics
- Financial services
- Brokerage services
It also excludes a business whose principal asset is the reputation or skill of one or more of its employees.
In addition, the statute excludes certain other types of businesses, including:
- Banking
- Insurance
- Financing
- Leasing
- Investing and similar businesses
- Farming
- Certain natural-resource and extraction businesses
- Hotels
- Motels
- Restaurants
- Similar hospitality businesses
Consequently, the correct question is not simply:
“Does this company provide services?”
The better question is:
“What does this company actually do, and does that activity fall within one of the businesses Congress specifically excluded?”
Businesses Near the Line Require More Analysis
Some companies operate in areas where the distinction is less obvious.
For example, a traditional general contractor may potentially qualify. But suppose the company is a design-build firm that derives a significant portion of its business from architectural or engineering services. Engineering and architecture are specifically excluded activities, making the analysis more complicated.
Likewise, a marketing company may qualify, while a company that primarily provides strategic advice to corporate clients might be characterized as an excluded consulting business.
A staffing company may qualify even though its business involves providing human capital to customers. A management-consulting company, by contrast, may be expressly excluded.
The label placed on the company is therefore less important than what the business actually does, how it earns its revenue and how its assets are deployed.
What About the “Reputation or Skill” Exclusion?
The statutory reference to businesses whose principal asset is the reputation or skill of one or more employees can also create confusion.
Almost every successful company depends upon skilled people. A software company depends upon programmers. A construction company depends upon experienced project managers and tradespeople. A manufacturing business depends upon engineers, managers and skilled employees.
That alone cannot reasonably mean that the company is automatically disqualified.
The issue becomes more significant when the economic value of the enterprise is predominantly tied to the personal reputation or individual skills of particular people rather than to an operating business with independent enterprise value.
For example, there is an obvious difference between a 100-person construction company with equipment, systems, contracts and established customer relationships and a corporation whose only meaningful business asset is the personal reputation and expertise of one highly compensated individual.
For closely held businesses built around a prominent founder, this issue deserves careful analysis.
The Active-Business Requirement
Even a company operating in a qualifying industry must satisfy Section 1202’s active-business requirements.
Generally, at least 80% of the corporation’s assets, measured by value, must be used in the active conduct of one or more qualified trades or businesses during substantially all of the applicable holding period.
This can become important when a successful operating company accumulates substantial cash, investment securities, real estate or other passive assets.
Section 1202 contains detailed rules governing working capital, investments, real property and subsidiaries. Consequently, business owners hoping to preserve QSBS treatment should not assume that qualifying at formation ends the analysis.
Section 1202 should be monitored as the company grows.
How Much Gain Can Be Excluded?
The potential exclusion is substantial.
For qualifying stock acquired after July 4, 2025, current law generally permits an eligible taxpayer to exclude gain subject to a $15 million per-issuer limitation, with the applicable exclusion percentage determined by the holding period.
The law therefore creates the possibility that a founder or investor could realize millions of dollars of gain on the sale of a successful company while excluding a substantial portion, and potentially all, of that gain from federal income taxation.
Different limitations and rules apply to stock acquired under earlier versions of Section 1202, so the acquisition date must always be considered.
Pass-Through Entities and QSBS
Another common misconception is that QSBS must always be owned directly by an individual.
Certain pass-through entities, including partnerships and S corporations, can own QSBS, and qualifying gain can potentially pass through to eligible partners or shareholders. However, Section 1202 contains additional requirements governing pass-through ownership, including rules concerning when the taxpayer held the pass-through interest and limitations based upon the taxpayer’s ownership interest when the QSBS was acquired.
The analysis can therefore become considerably more complicated than direct individual ownership.
The important distinction is that an S corporation or partnership cannot itself issue QSBS, because the issuing company must be a C corporation. But an S corporation or partnership may potentially own stock issued by a qualifying C corporation and pass eligible Section 1202 gain through to its owners.
QSBS and Grantor Trust Planning
Trust ownership can also play an important role in Section 1202 planning.
In many cases, a simpler approach is to have qualifying Section 1202 stock owned directly by a properly structured Bridge Trust® that is treated as a grantor trust for federal income-tax purposes.
Because a grantor trust is generally disregarded as a separate taxpayer for federal income-tax purposes during the grantor-trust period, ownership through the trust can preserve the tax relationship between the grantor and the QSBS while simultaneously integrating the stock into the owner’s broader asset-protection and estate-planning structure.
However, QSBS trust planning can become considerably more sophisticated where multiple trusts, nongrantor trusts or transfers of existing QSBS are contemplated. Those strategies require separate analysis of the Section 1202 holding-period, transfer and taxpayer-level limitation rules.
Planning Should Begin Before the Business Becomes Valuable
One of the biggest mistakes entrepreneurs make with Section 1202 is waiting until they are preparing to sell the company before considering QSBS.
By then, many of the important decisions have already been made.
Entity selection, capitalization, stock issuance, asset levels and ownership structure can all affect qualification.
Consider two entrepreneurs who each start a construction business that eventually sells for $30 million.
One begins as an LLC taxed as an S corporation and remains that way for years. The other forms an appropriately capitalized C corporation, issues qualifying stock while the company is well below the applicable asset ceiling, operates a qualifying construction business and satisfies the applicable holding-period requirements.
The businesses may be economically almost identical.
Their federal tax consequences upon sale could be dramatically different.
That is why Section 1202 should be viewed as a business-formation and ownership-planning issue, rather than merely a tax provision to examine immediately before a sale.
Conclusion
Section 1202 represents one of the most powerful tax incentives available to founders and investors in qualifying American businesses.
It is also considerably broader than many entrepreneurs realize.
A business does not need to be a Silicon Valley startup to qualify. A general contractor, construction company, manufacturer, software company, distributor, logistics company, retailer, e-commerce business and many other ordinary operating businesses may potentially qualify, provided the corporation and its shareholders satisfy the statutory requirements.
The critical distinction is that Section 1202 does not exclude all businesses that provide services. It excludes specifically identified professional, financial and other businesses.
For entrepreneurs starting or restructuring businesses with meaningful growth potential, the question should therefore be asked early:
Could this business qualify for Section 1202, and if so, should we structure the company and its ownership today to preserve that opportunity?
The potential tax benefit can be significant enough that the question deserves consideration long before an eventual sale is on the horizon.
