QSBS Before a Sale: Prove Eligibility Before Counting the Savings

Section 1202 concerns qualifying small-business stock, with requirements involving the issuer, original issuance, holding period, assets, and business activities. An ownership interest in a small company is not automatically QSBS. The applicable rules and exclusion limits depend on the stock’s dates and circumstances.

Prepare an ownership timeline: when you acquired each block, what you paid, how you acquired it, and whether exchanges, gifts, redemptions, or reorganizations occurred. Ask your tax professional which events need separate analysis.

A useful starting file includes stock issuance records, purchase or subscription documents, capitalization records, and the company information your CPA or attorney requests. Do not treat a verbal assurance from the company as a substitute for the underlying facts.

Divide the list into confirmed, estimated, and missing. A missing fact should remain visible in the planning discussion rather than quietly turning into a favorable assumption.

Illustration: an owner expects $8 million of usable cash if a tax benefit applies, but $6 million if it does not. At $240,000 of annual portfolio withdrawals, the initial withdrawal rate is 3% in one case and 4% in the other. Neither percentage proves retirement is secure. The difference shows why eligibility belongs in the personal planning conversation before a deal is treated as sufficient.

Use the QSBS calculator to organize a first screen, then carry only the tax-team-confirmed amount into the sale-proceeds and retirement models. Review state treatment separately.

Ask: which facts support our conclusion, which remain unverified, and what changes if the exclusion is smaller or unavailable? A written explanation of those assumptions is more useful than a headline savings number.
