1. Overview of Section 1202

Qualified Small Business Stock (QSBS) is a tax designation established under Section 1202 of the Internal Revenue Code (IRC). Its primary goal is to incentivize long-term investment in domestic small businesses by offering significant tax breaks to early-stage investors and founders.

The policy has evolved significantly over the decades. Historically, the tax exclusion was limited to 50%. However, following the 2010 Small Business Jobs Act and the 2015 PATH Act, the exclusion was increased to 100% for shares acquired after September 27, 2010. This makes it one of the most lucrative tax incentives in the U.S. financial landscape, particularly for those in the high-growth tech and blockchain sectors.

2. Eligibility Requirements for Corporations

To qualify as qualified small business stock, the issuing entity must meet strict criteria at the time the stock is issued:

Domestic C Corporation Status: The company must be a U.S.-based C corporation. S-corporations, partnerships, and LLCs are generally ineligible for QSBS benefits.
Gross Asset Test: According to recent updates, the company’s aggregate gross assets must not have exceeded $50 million at any time before or immediately after the stock issuance. Note that as of early 2025, certain legislative updates may adjust these thresholds for inflation or specific development zones.
Active Business Requirement: At least 80% of the corporation's assets must be used in the active conduct of one or more qualified trades or businesses.
Qualified Sectors: Technology, manufacturing, and retail typically qualify. However, service-based sectors like banking, law, hospitality, and farming are specifically excluded from QSBS status.

3. Shareholder Eligibility and Holding Periods

Not everyone who owns shares can claim the QSBS exclusion. Only non-corporate taxpayers, such as individuals, trusts, and certain pass-through entities, are eligible. C-corporations that own stock in other companies cannot claim the Section 1202 exclusion.

The original issuance requirement dictates that the stock must be acquired directly from the corporation in exchange for money, property, or services (such as sweat equity). Buying shares from another shareholder on a secondary market usually disqualifies the stock from being QSBS.

The most critical component is the five-year rule. To claim the tax exclusion, the shareholder must hold the stock for at least five years. According to reports as of March 2025, new legislative discussions suggest a tiered exclusion for shares issued after July 2025, potentially allowing partial benefits for 3-year or 4-year holding periods to further stimulate venture activity.

4. Tax Benefits and Limitations

The primary advantage of qualified small business stock is the exclusion of capital gains from federal income tax. For eligible stock, 100% of the gain is excluded, and this gain is also exempt from the Alternative Minimum Tax (AMT) and the 3.8% Net Investment Income Tax (NIIT).

However, there are caps on the total benefit. The exclusion is limited to the greater of:

$10 million per issuer; or
10 times the taxpayer’s aggregate adjusted basis in the stock.

Investors should also be aware of state-level treatment. While many states mirror federal rules, others—most notably California—do not recognize the QSBS exclusion and will tax the gains at the state level.

5. Strategic Provisions for Investors

For those who sell their qualified small business stock before the five-year mark, Section 1045 Rollovers provide a safety net. This provision allows an investor to defer capital gains by reinvesting the proceeds into a new qualified small business within 60 days of the sale.

In the venture capital world, QSBS dramatically changes the "exit math." For a founder or early investor in a startup, the ability to walk away with $10 million tax-free can represent a significantly higher net return than traditional equity in larger, more established firms. Additionally, gifting QSBS to family members or non-grantor trusts can sometimes multiply the $10 million exclusion cap, though this requires complex tax planning.

6. Compliance and Documentation

To successfully claim the exclusion, documentation is paramount. Investors should request a QSBS Attestation Letter from the company at the time of investment, confirming that the company meets the gross asset and active business tests. Ongoing monitoring is also required, as excessive share repurchases by the company can occasionally "taint" or disqualify the stock’s QSBS status. While Bitget provides tools for tracking traditional assets, for private equity like QSBS, maintaining a physical or digital paper trail of the original purchase is essential.
