Introduction
Startup founders and investors often face a daunting challenge: navigating the complex tax landscape when selling their business. Inexperienced CPAs or tax preparers may overlook critical provisions, leading to overpaid taxes or missed savings opportunities.

Understanding QSBS and Its Tax Benefits
The QSBS provision, codified under IRC § 1202, allows non-corporate taxpayers to exclude up to 100% of capital gains from selling qualified stock, fostering investment in small businesses. For stock acquired on or before July 4, 2025, the issuing corporation must be a domestic C corporation with gross assets not exceeding $50 million at issuance (IRC § 1202(d)). The One Big Beautiful Bill Act, enacted July 4, 2025, raises this threshold to $75 million for stock acquired thereafter, adjusted for inflation. The corporation must engage in an active trade or business, excluding service sectors like law, health, or finance (IRC § 1202(e)). Taxpayers must acquire the stock at original issuance and hold it for at least five years (IRC § 1202(a)).
The exclusion cap is the greater of:
- $10 million ($15 million for post-July 4, 2025 acquisitions) per issuer, or
- 10 times the adjusted basis of the stock (IRC § 1202(b)).
Any non-excludable gain is taxed at long-term capital gains rates, typically 20% for high earners, plus 3.8% Net Investment Income Tax (IRC § 1411). For further details, consult IRS Publication 550.
Key Forms for Reporting
- Form 8949: Report the sale of QSBS, using adjustment code “Q” to denote the exclusion.
- Schedule D (Form 1040): Summarize capital gains and losses, reflecting the excluded amount.
- Form 1099-B: Provided by brokers to document the sale proceeds.
Detailed Example: Maximizing QSBS Savings
Consider Jane, a startup founder who acquires $600,000 of QSBS in her tech C corporation on March 1, 2020 (pre-July 2025). The corporation’s gross assets are $40 million at issuance, qualifying under IRC § 1202(d). On August 1, 2025, Jane sells her stock for $8 million, realizing a $7.4 million gain. Under IRC § 1202(b), her exclusion limit is the greater of:
- $10 million, or
- 10 times her basis ($600,000 × 10 = $6 million).
Jane excludes $7.4 million (the entire gain, as it’s below $10 million), owing no tax on the sale. Without QSBS, at a 20% capital gains rate plus 3.8% NIIT, her tax liability would be approximately $1.75 million. By leveraging QSBS, Jane saves this entire amount, retaining more capital for reinvestment or personal use. For post-July 2025 acquisitions, the exclusion cap would be $15 million, offering even greater potential savings.
Alternative Scenario
If Jane’s gain were $12 million, she’d exclude $10 million, with $2 million taxed at 23.8% (20% + 3.8% NIIT), resulting in a $476,000 tax bill—still a significant saving compared to $2.86 million without QSBS.
Step-by-Step Guide for Taxpayer Compliance
To ensure compliance with IRS requirements and maximize QSBS benefits, follow these steps:
- Verify Corporate Eligibility: Confirm the issuer is a domestic C corporation with assets under $50 million (or $75 million post-July 4, 2025) at issuance, per IRC § 1202(d). Review formation documents and financial statements.
- Confirm Active Business: Ensure the corporation engages in a qualifying trade or business, excluding prohibited sectors (IRC § 1202(e)).
- Document Stock Acquisition: Acquire stock at original issuance (e.g., via founder shares or investment) and retain stock certificates to prove the acquisition date.
- Hold for Five Years: Maintain ownership for at least five years to meet IRC § 1202(a) requirements, tracking via dated records.
- Track Adjusted Basis: Record the initial investment and any adjustments (e.g., additional contributions) per IRC § 1016.
- Execute the Sale: Upon selling, obtain Form 1099-B from your broker and calculate the gain under IRC § 1001 (sale price minus adjusted basis).
- Report the Exclusion: On Form 8949, report the sale with code “Q” to claim the QSBS exclusion, then transfer to Schedule D (Form 1040). File by April 15, 2026, or extend with Form 4868.
- Retain Records: Keep all documentation (certificates, financials, 1099-B) for at least three years post-filing, as required by IRC § 6001.

Common Pitfalls to Avoid
- Non-Qualifying Businesses: Ensure the corporation isn’t in an excluded sector (e.g., consulting, finance) per IRC § 1202(e).
- Asset Threshold Exceedance: Verify assets don’t exceed the $50 million/$75 million cap at issuance, including cash and property.
- Early Sale: Selling before the five-year holding period disqualifies the exclusion, though IRC § 1045 may allow a tax-deferred rollover into new QSBS.
- Improper Documentation: Failure to substantiate acquisition or holding period can trigger IRS audits, risking disallowance.
