QSBS Redemption Rules & Stock Buybacks

A corporate stock buyback can affect QSBS treatment for shares issued before or after the purchase. Section 1202 has a shareholder-and-related-person rule and a separate significant-redemptions rule. Apply both to each relevant issuance; the shorthand “$10,000 and 2%” leaves important requirements unexplained.

This guide focuses on redemptions. For original issuance, active business, holding periods, and exclusion limits, start with QSBS tax planning. The governing sources are Section 1202(c)(3) and Treasury Regulation 1.1202-2.

Compare the two redemption tests

Apply each test separately to each stock issuance
Question	Taxpayer or related person	Significant redemptions
Testing period	Four years beginning two years before issuance	Two years beginning one year before issuance
Relevant sellers	The taxpayer and persons related under Sections 267(b) or 707(b)	Company purchases across holders
De minimis screen	Amount paid exceeds $10,000 AND more than 2% of the taxpayer/related-person stock is acquired	Amount paid exceeds $10,000 AND more than 2% of all outstanding stock is acquired
Additional value threshold	No separate 5% company-value test	Purchased stock value exceeds 5% of all stock value at the beginning of the testing period

The current eCFR text sets out the complete rules and exceptions. “Exceeds” and “more than” matter at a boundary. The regulation’s de minimis conditions are conjunctive; exceeding the dollar amount alone does not complete either percentage analysis.

Build a timeline for each issuance

Use issuance dates rather than a single company-wide date. Identify purchases already completed and those proposed within the relevant forward period. A purchase affecting one stock lot may fall outside the testing window for another.

For a fictional issuance on June 15, 2026, the four-year period begins June 15, 2024, and the two-year period begins June 15, 2025. Their last days are June 14, 2028, and June 14, 2027, respectively. Transactions near a boundary require careful confirmation of the actual issuance and purchase dates.

For SAFEs and convertible instruments, identify when stock is acquired under the applicable tax treatment before constructing the calendar. Read SAFE classification and holding periods.

Use the correct value and denominator

For each purchase, the 2% calculation uses the purchased stock’s value at that purchase divided by the relevant stock value immediately before the purchase. The shareholder-specific denominator includes the taxpayer’s and related persons’ holdings; the company-wide denominator includes all outstanding stock. For multiple purchases, add the separately calculated purchase percentages.

The 5% test uses purchased-stock values at the respective purchases against all stock value at the beginning of the two-year period. It is not the same denominator as the immediately-before-purchase 2% screen.

Keep amount paid, stock value, note principal, par value, and SAFE conversion caps separate in the workpapers. A board finding for a particular common-stock grant does not automatically value every class or investment instrument at every testing date. A share count alone may be misleading where rights differ. See stock valuation and equity planning.

Section 1202 uses the relationships specified in Sections 267(b) and 707(b). Under Section 267, family relationships include ancestors and lineal descendants, among other specified relatives. A parent’s independent investment therefore deserves review when the company purchases a founder child’s stock.

Trusts, holding entities, partnerships, indirect ownership, and their tax classifications can also matter. Do not assume a separate name on the capitalization table establishes independence, or that every relative is included. Document the relationship analysis before selecting the denominator.

Check exceptions and other purchases

Review each transaction for an applicable regulatory exception before including it in a calculation. Service-termination repurchases require particular care: the rule expressly addresses qualifying employee and director departures, while the independent-contractor provision is reserved. Our unvested stock repurchase guide covers this distinction.

Then collect other purchases within the testing period. A small transaction reviewed alone can produce an incomplete answer when other purchases also count. Document the reason a purchase was included or disregarded.

What a useful redemption workpaper contains

Record each issuance and holder, the applicable windows, sellers and relationships, purchase dates, consideration, valuation evidence, exceptions, and separate calculations for each test. Preserve the sources and assumptions alongside the conclusion.

If a proposed payment involves replacing a founder investment with a note, first determine whether the exchange itself is a stock purchase. See founder loans and SAFE restructuring. The redemption formulas cannot answer that preliminary classification question.

Frequently Asked Questions

Can a buyback affect investors who did not sell shares?

Yes. The significant-redemptions rule can affect stock issued to other holders within its testing period when its conditions are met.

Is a payment over $10,000 automatically disqualifying?

No. Apply the applicable percentage conditions, testing window, exceptions, and, for significant redemptions, the additional 5% value test.

Can I use par value for the calculation?

Par value alone does not establish the relevant stock value. Support values for the instruments and dates required by each test.
