Section 1202 of the Internal Revenue Code offers one of the most powerful tax incentives available to investors in small businesses. This provision allows individuals who hold qualified small business stock (QSBS) to permanently exclude a portion, or even all, of their capital gains from federal income tax when they sell that stock. Unlike tax deferrals that simply delay when you owe, the Section 1202 exclusion eliminates the tax entirely. You can review the statute itself in the Internal Revenue Code at Cornell Law.
For founders, angel investors, and early-stage shareholders, understanding Section 1202 can mean the difference between paying hundreds of thousands of dollars in capital gains tax and paying nothing at all. The stakes are high, and the rules are specific, so getting the details right matters. The right tax advisory services can help you confirm eligibility before a sale closes.
What is Section 1202 and why does it exist?
Section 1202 was enacted to encourage investment in small businesses by reducing the tax burden on investors who take the risk of backing early-stage companies. Congress recognized that small businesses drive job creation and innovation, and that investors needed a meaningful incentive to put capital into ventures that carry higher risk than established public companies.
The core mechanism is straightforward: if you acquire qualified small business stock at original issuance and hold it for the required period, you can exclude a percentage of the gain when you sell. The exclusion is permanent. It is not a deferral, a credit, or a deduction. The gain simply does not count as taxable income.
This makes Section 1202 fundamentally different from other tax provisions like Section 1031 exchanges or opportunity zone deferrals, which postpone taxation rather than eliminating it. For investors who meet the QSBS requirements, the Section 1202 gain exclusion represents a rare opportunity to build wealth without a federal capital gains tax hit. The IRS guidance on capital gains and losses explains how the broader gain rules interact with exclusions like this one.
QSBS requirements: what qualifies as Section 1202 stock?
Not every small business investment qualifies for the Section 1202 exclusion. The Internal Revenue Code sets several specific QSBS requirements that both the company and the investor must satisfy.
Company requirements
The issuing company must be a domestic C corporation that meets a gross asset test at the time the stock is issued and immediately after. For stock issued on or before July 4, 2025, the company’s aggregate gross assets must be $50 million or less. For stock issued after July 4, 2025, the One Big Beautiful Bill Act raised that threshold to $75 million, with annual inflation adjustments scheduled to begin in 2027. The company must also use at least 80% of its assets in the active conduct of a qualified trade or business. Certain industries are excluded, including services in the fields of health, law, accounting, consulting, financial services, and brokerage, along with banking, insurance, farming, and hospitality.
Investor requirements
The investor must acquire the stock at original issuance, meaning directly from the company in exchange for money, property, or services. Stock purchased on the secondary market does not qualify. The investor must be an individual (or a pass-through entity whose owners are individuals), and they must hold the stock for the required holding period before selling.
The per-issuer dollar cap
Even when all requirements are met, the Section 1202 exclusion is subject to a per-issuer cap. An individual can exclude the greater of a fixed dollar amount or 10 times their adjusted basis in the stock. For stock acquired on or before July 4, 2025, the fixed amount is $10 million. For stock acquired after July 4, 2025, the One Big Beautiful Bill Act increased the fixed amount to $15 million, with annual inflation adjustments scheduled to begin in 2027. This cap applies per issuer, so an investor with qualified small business stock in multiple companies can potentially exclude gains from each one separately.
Section 1202 exclusion percentages and holding periods
The percentage of gain you can exclude under Section 1202 depends on when the stock was originally issued. Congress has adjusted these percentages several times since the provision was first enacted in 1993, and the One Big Beautiful Bill Act introduced further changes in 2025.
Here is the current schedule of Section 1202 gain exclusion percentages:
| Stock Issue Date | Holding Period | Exclusion Percentage |
| — | — | — |
| August 11, 1993 – February 17, 2009 | More than 5 years | 50% |
| February 18, 2009 – September 27, 2010 | More than 5 years | 75% |
| September 28, 2010 – July 4, 2025 | More than 5 years | 100% |
| July 5, 2025 – present | More than 3 years | 50% |
| July 5, 2025 – present | More than 4 years | 75% |
| July 5, 2025 – present | More than 5 years | 100% |
For stock issued between September 28, 2010 and July 4, 2025, the full 100% exclusion applies after a five-year holding period. This has been the most favorable window in the history of Section 1202, and investors who acquired QSBS during this period stand to benefit the most. Coordinating these dates with a transaction advisory team before a sale helps confirm which schedule applies.
How the One Big Beautiful Bill changed Section 1202
The One Big Beautiful Bill Act, signed into law in July 2025, introduced a graduated exclusion structure for stock issued after July 4, 2025. Previously, investors had to wait five full years to receive any exclusion benefit. Under the new rules, investors can begin excluding gains after just three years of holding.
This tiered approach, 50% after three years, 75% after four, and 100% after five, gives investors earlier access to partial tax benefits while still rewarding those who hold for the full five-year period. The change is particularly meaningful for founders and early employees who may need liquidity before the five-year mark. A founder who sells QSBS after four years of holding will now exclude 75% of the gain rather than receiving no exclusion at all.
The Act also expanded two other key limits for stock issued after July 4, 2025: the per-issuer exclusion cap rose from $10 million to $15 million, and the company-level gross asset threshold rose from $50 million to $75 million. Both figures are scheduled to be adjusted for inflation beginning in 2027.
The new rules apply only to stock issued after July 4, 2025. Stock issued on or before that date continues to follow the original schedule, which requires a full five-year hold for any exclusion and retains the $10 million cap and $50 million gross asset limit.
How to plan around the Section 1202 exclusion
Tax planning around Section 1202 requires attention to timing, entity structure, and documentation. Several strategies can help investors maximize the benefit.
Confirm C corporation status early
Because Section 1202 applies only to stock issued by a C corporation, founders should consider their entity structure from the beginning. An LLC taxed as a partnership cannot issue QSBS. If a company converts from an LLC to a C corporation, only stock issued after the conversion may qualify, and the gross asset test is measured at the time of issuance.
Track the gross asset threshold
The gross asset limit is tested at the time the stock is issued and immediately after the issuance. The threshold is $50 million for stock issued on or before July 4, 2025, and $75 million for stock issued after that date. Companies approaching the applicable mark should consider the timing of future fundraising rounds carefully. Once the company’s gross assets exceed the threshold that applies to a given issuance, stock issued after that point will not meet the qualified small business stock requirements.
Document everything
The IRS may request proof that the stock qualifies under Section 1202. Investors and companies should maintain records showing the company’s gross assets at the time of issuance, the nature of the business activities, the date and manner of stock acquisition, and the holding period. A well-documented file makes it far easier to claim the exclusion and defend it if questioned.
Consider gifting and estate planning
Section 1202 stock can be gifted to family members, and the recipient inherits the donor’s holding period and basis. This means a founder who has held QSBS for four years can gift it to a child, and the child only needs to hold it for one more year to reach the five-year threshold. This strategy can multiply the per-issuer cap, $10 million for older stock or $15 million for stock issued after July 4, 2025, across multiple family members.
Common mistakes that disqualify Section 1202 treatment
Several pitfalls can cause investors to lose the Section 1202 exclusion entirely. The most common include failing to acquire stock at original issuance (buying on the secondary market does not qualify), holding stock in a company that later shifts more than 20% of its assets to non-qualifying activities, redeeming stock in a way that triggers the redemption rules under Section 1202(c)(3), and failing to meet the holding period before selling. These are the kinds of issues that benefit from coordinated accounting services and recordkeeping throughout the holding period.
Another frequent mistake is assuming that stock options automatically qualify. Incentive stock options (ISOs) and non-qualified stock options (NQSOs) do not become QSBS until the options are exercised and shares are actually issued. The holding period begins on the exercise date, not the grant date.
Investors should also be aware that Section 1202 does not apply to S corporations. If a company elects S corporation status at any point during the investor’s holding period, the stock may lose its qualified status.
Frequently Asked Questions
What is Section 1202 qualified small business stock?
Section 1202 qualified small business stock (QSBS) is stock issued by a domestic C corporation that meets the gross asset test, $50 million or less for stock issued on or before July 4, 2025, and $75 million or less for stock issued after that date, acquired at original issuance in exchange for money, property, or services. The company must use at least 80% of its assets in an active qualified trade or business. Stock that meets these criteria may be eligible for a capital gains exclusion when sold.
What are the QSBS requirements to qualify for the gain exclusion?
The main QSBS requirements include acquiring stock directly from a C corporation at original issuance, the company meeting the gross asset test at the time ($50 million or less for stock issued on or before July 4, 2025, or $75 million or less afterward), and the company conducting an active trade or business (excluding certain service industries). The investor must also hold the stock for the required period: at least three years under the rules for stock issued after July 4, 2025 for a partial exclusion, or five years for the full 100% exclusion.
How much capital gains tax can you exclude under Section 1202?
An individual can exclude the greater of a fixed dollar amount or 10 times their adjusted basis in the stock, per issuing company. The fixed amount is $10 million for stock acquired on or before July 4, 2025, and $15 million for stock acquired after that date, with inflation adjustments scheduled to begin in 2027. For stock issued after July 4, 2025, the exclusion percentage ranges from 50% (after 3 years) to 100% (after 5 years). For stock issued between September 28, 2010 and July 4, 2025, the full 100% exclusion applies after a five-year hold.
Does Section 1202 apply to LLCs or S corporations?
Section 1202 applies only to stock issued by domestic C corporations. LLCs taxed as partnerships and S corporations do not qualify. If a company converts from an LLC to a C corporation, only stock issued after the conversion date may be eligible, and the company must meet the gross asset and active business tests at that time.
How did the One Big Beautiful Bill change the Section 1202 holding period?
The One Big Beautiful Bill introduced a graduated exclusion for stock issued on or after July 5, 2025. Investors can now exclude 50% of gains after three years, 75% after four years, and 100% after five years. Previously, no exclusion was available until the full five-year holding period was met. Stock issued before July 5, 2025 follows the original schedule.
How do you report the Section 1202 exclusion on your tax return?
The Section 1202 exclusion is reported on Schedule D and Form 8949 of your federal income tax return. You report the full gain from the sale, then subtract the excluded portion. The IRS may require documentation showing the stock met all QSBS requirements, so retaining records of the issuance date, purchase price, company gross assets, and business activities is essential.
