Qualified Small Business Stock: Redemption Issues

By Joe Wallin | July 6, 2026 | ~7 min read

A stock buyback in the wrong window can disqualify Qualified Small Business Stock (QSBS) — not just the redeemed shares, but every share issued near the redemption. Section 1202(c)(3) and Treas. Reg. §1.1202-2 treat corporate repurchases within defined testing windows as disqualifying events, which means a company that buys back shares to clean up its cap table can destroy the exclusion for shareholders who never sold a share.

The interaction between stock redemptions and QSBS qualification is one of the most misunderstood—and most dangerous—areas of startup tax planning. Founders and investors have lost millions in potential tax exclusions because their company's buyback strategy wasn't run through a Section 1202 lens first. This post walks you through how redemptions can disqualify QSBS, what the law actually allows, and how to protect yourself.

What Is QSBS? A Quick Refresher on the Updated Rules

QSBS is a tax provision under Section 1202 of the Internal Revenue Code that lets you exclude a massive portion of your gain when you sell stock in a qualified small business. The recent One Big Beautiful Bill Act (OBBBA), effective July 4, 2025, made these rules significantly better.

For stock issued after July 4, 2025, you now get these improvements: your per-issuer exclusion cap increased from $10 million to $15 million in gains, the corporate gross asset threshold rose from $50 million to $75 million, and—perhaps most important—you can now get partial exclusions even if you hold the stock less than five years. You'll exclude 50% of your gain after holding for 3 years, 75% after 4 years, and 100% after 5 years.

If your stock was issued before July 4, 2025, the old rules still apply: you need a more-than-five-year holding period to get the 100% exclusion, and you're stuck with the $10 million per-issuer cap. But the redemption rules we're about to discuss apply to both new and old QSBS equally.

The Redemption Problem: When the Company Buys Back Your Stock

Section 1202(c)(3) contains two separate anti-churning rules. The first, under (c)(3)(A), targets redemptions from you or a related person: if the corporation buys back more than a de minimis amount of its stock from you (or a related party) at any time during the four-year period running from two years before to two years after your shares are issued, your stock is disqualified. That rule reaches only your stock and stock of persons related to you — not redemptions from unrelated shareholders. The second rule, below, is broader—and catches more people.

The concern Congress is addressing is this: if the company can essentially shuffle around its own stock or conduct redemptions that feel like they're accomplishing things other than genuine business needs, the value of the QSBS exclusion could be easily manipulated. So the IRS has built in gatekeepers.

When your company does a share buyback or redemption, it's acquiring stock from you. If that acquisition isn't carefully structured, it can disqualify your entire QSBS position. This isn't a per-share rule—the disqualification generally applies to all your holdings in that company if the problem occurs.

The Significant Redemption Test: The Real Gatekeeper

Section 1202(c)(3)(B) is the rule that catches most founders and investors, because it applies to redemptions from anyone—not just you. A stock issuance is disqualified if, during the two-year window running from one year before the issuance to one year after, the corporation bought back its stock with an aggregate value exceeding 5% of the value of all its stock, measured at the start of that window.

There is just one threshold here, and it turns on value, not earnings: the buybacks during the window must exceed 5% of the aggregate value of all the corporation's stock as of the beginning of the window. Each redemption is valued as of the time it occurs, and they are aggregated. Stay at or below that 5% line and the significant-redemption rule isn't triggered; cross it, and every share issued in that window loses QSBS status.

The math in practice. Suppose the corporation's outstanding stock was worth $10 million at the beginning of the two-year window surrounding your issuance. The redemption budget for that entire window is $500,000 — 5% of the value at the window's start (Treas. Reg. §1.1202-2(b)(1)). Aggregate repurchases of more than $500,000 during the window, valued as of each purchase, disqualify every share issued in the window. Note the asymmetry: the 5% denominator is frozen at the window's start, but each redemption counts at its value when it happens. A fast-growing company burns through its budget quickly, because buybacks priced at appreciated values are measured against a denominator set when the company was worth less.

The first-year founder trap. The denominator is the value of all the corporation's stock "as of the beginning of" the two-year period — which, for stock issued in a company's first year, is a date when the company barely existed or was worth almost nothing. Read literally, that makes 5% of a near-zero denominator a near-zero redemption budget, so almost any non-de-minimis redemption could be "significant" as to first-year issuances. Commentators have urged the IRS to fix this by starting the testing period no earlier than the date of formation, but no guidance has issued. Until it does, treat any redemption in a company's first two years as presumptively dangerous to founder QSBS.

The key insight here is the timing window. For the significant-redemption rule, that window runs from one year before your issuance to one year after; the related-party rule reaches wider, two years on each side. A redemption outside the relevant window generally won't disqualify your QSBS. The related-party rule applies to you and related parties collectively, so you need to aggregate redemptions across family members and controlled entities.

The De Minimis Safe Harbor and Other Exceptions

The regulations provide more breathing room than people assume. Under Treas. Reg. §1.1202-2, a purchase exceeds the de minimis threshold — and therefore counts toward the disqualification tests — only if BOTH prongs are exceeded: the aggregate amount paid is more than $10,000 AND more than 2% of the relevant stock is purchased. Fail either prong and the purchase is disregarded: a sub-2% buyback is de minimis no matter how many dollars it involves, and a purchase of $10,000 or less is de minimis no matter the percentage. (The 2% is measured against the stock held by you and related persons for the related-party rule, and against all outstanding stock by value for the significant-redemption rule.) And don't confuse this de minimis disregard with the significant-redemption rule's separate 5%-of-value threshold — they are different tests.

Separately, the regulations disregard certain redemptions entirely, regardless of size, when they're tied to specific events: a holder's death, disability or mental incompetency, divorce, or termination of services (Treas. Reg. §1.1202-2(d)). And one more carve-out that matters for the cap-table scenario: under Treas. Reg. §1.1202-2(c), a transfer of stock by a shareholder to an employee or independent contractor is not treated as a purchase by the corporation at all — a founder handing shares directly to a new hire doesn't count against these thresholds. It's corporate repurchases that do. The bottom line is that not every redemption disqualifies QSBS, but you need to run the math before you assume you're safe.

Real-World Scenarios Where This Matters Most

Share Buybacks for Cap Table Management: The most common scenario is a mature startup that wants to buy back shares from employees who've left or early angels who want liquidity. If your company is doing a secondary sale or tender offer, and the amounts being repurchased push past those thresholds in the critical timing window, QSBS holders can lose their status without even selling their own shares. The buyback wasn't their choice, but they bear the tax consequence.

Preferred Stock Redemptions at Financing Rounds: Sometimes new investors come in and old preferred stock gets redeemed or converted. If the corporation is redeeming preferred shares it previously issued, and this happens within the two-year lookback or one-year forward window relative to new QSBS issuance, you have a problem. This is especially dangerous for founders who hold both common and preferred stock.

Earnout Redemptions and Contingent Consideration: Acquisitions sometimes involve earnout payments structured as stock redemptions or cash paid by redeeming outstanding shares. If the target company is redeeming shares shortly before or after issuing new QSBS shares (which can happen in complex post-acquisition restructurings), the timing trap triggers.

Equity Compensation Adjustments: Companies that repurchase or net-settle shares to cover tax withholding at vesting or exercise, or to adjust employee holdings, need to be careful. Every share withheld or repurchased counts toward the redemption thresholds.

How to Protect Your QSBS Status: Practical Planning Tips

If your company is contemplating any kind of redemption, buyback, or share repurchase, the first step is transparency with your tax advisor. Ideally, the company should run the numbers before announcing a buyback program. If the redemptions stay within the de minimis disregard — no more than $10,000 paid, or no more than 2% of the relevant stock — they don't count against the tests at all. Above that, aggregate every purchase in the window against the 5%-of-value significant-redemption threshold, and separately check whether any purchase came from an issuee or a related person within the wider two-year windows.

Timing is everything. If you know your company is planning a significant redemption, can you time the issuance of new QSBS shares outside the critical window? A redemption that disqualifies QSBS from issuance before it happens might not affect QSBS issued after the one-year lookforward period ends. Conversely, if you're going to be issued new QSBS, confirm that no major redemptions occurred in the preceding two years.

Document everything. The company should maintain clear records of all stock acquisitions, redemptions, and repurchases, along with the dates and amounts. When you need to substantiate QSBS status to the IRS, this contemporaneous documentation is invaluable.

Consider structural alternatives. If the company needs liquidity for departing employees, direct cash payments might be better than stock redemptions. If the company wants to optimize its cap table, a new class of stock or a recapitalization might accomplish the goal without triggering the redemption rules. These alternatives require careful analysis, but they're worth exploring before defaulting to redemptions.

For QSBS holders with options and restricted stock, the analysis gets more complex. Options themselves are never QSBS — the stock you receive on exercise can be, whether the option was an ISO or an NSO, because exercise is an acquisition at original issuance. The §1202 holding period runs from exercise for vested-share exercises — and from grant for restricted stock with a timely 83(b) election. The exception: shares acquired subject to vesting without a timely 83(b) election. Under §83, those shares aren't treated as acquired for tax purposes until they vest, so both the holding period and the §1202 original-issuance date start at vesting. This is one more reason the 83(b) filing matters for QSBS planning. But if your company is redeeming and you're holding both vested common and unvested restricted stock, the timing of vesting relative to redemptions matters.

What If You've Already Been Hit?

If your company has already conducted a redemption and you're worried about QSBS status, the analysis depends on timing. If the redemption occurred outside the critical window relative to your stock issuance, you may have no issue. If it's within the window, run the numbers: was the purchase above the de minimis floor, and did aggregate purchases exceed 5% of the value of all stock at the start of the window (or involve you or a related person at any size above de minimis)? The good news is that not every redemption disqualifies QSBS—it depends on magnitude and timing relative to your specific issuance date.

The defenses that actually appear in the regulation are the de minimis disregard and the §1.1202-2(d) exceptions for termination of services, death, disability, and divorce. Whether a particular redemption fits one is fact-specific — worth a detailed analysis with a tax advisor who knows Section 1202 before you concede the exclusion is gone.

Planning Forward with the New OBBBA Rules

The OBBBA made QSBS more valuable by expanding the exclusion and loosening the holding periods. That's great news. But it's also made planning more important, because the tax stakes are higher. A company that could previously afford to be casual about redemptions might now face a disqualification that costs millions.

If your startup is raising capital or doing any kind of corporate restructuring, make sure your cap table and tax advisors are talking. The QSBS redemption rules are technical and easy to overlook, but they're not hard to follow once you understand the mechanics. A little planning today can save you from a catastrophic tax bill later.

The bottom line: stock redemptions don't automatically disqualify QSBS, but they can if you don't understand the rules. If your company is considering any form of share repurchase, buyback, or redemption, get a tax opinion before you pull the trigger. The cost of analysis is trivial compared to the risk of losing an exclusion worth millions.

Questions About Your Specific Situation?

QSBS rules are dense, and redemption interactions are genuinely complex. If you're holding QSBS and your company is planning a buyback, or if you're unsure about your own stock's status, I'd recommend talking to a tax professional who understands Section 1202 in detail. Every situation is different, and the stakes are too high for assumptions.
