Don’t Accidentally Disqualify Your QSBS by “Resetting” It

Replacing a stock certificate or restructuring a company does not, by itself, give existing QSBS a new acquisition date for the 2025 tax changes. Some transactions preserve QSBS and carry over the holding period; others produce taxable gain or replacement shares that do not qualify. Identify the applicable rule before treating a recapitalization as either a tax benefit or a disqualification.

• Exclusion percentages and the dollar-limit regime follow the shareholder's statutory acquisition date, including applicable holding-period tacking. Stock acquired on or before July 4, 2025 remains subject to the earlier rules; qualifying later acquisitions can use the three-, four- and five-year tiers.
• The gross-assets ceiling follows issuance: $50 million for stock issued on or before July 4, 2025, and $75 million for later issuances, with applicable indexing. Issuance and statutory acquisition are separate tests.
• Section 1202(f) can preserve QSBS on a conversion solely into another class of stock in the same corporation. Section 1202(h)(4) can preserve treatment in qualifying §351 exchanges and §368 reorganizations, subject to its conditions and limitations. These provisions carry forward the relevant holding period rather than supplying a new-regime election.

Startup founders and investors love Section 1202's qualified small business stock (QSBS) exclusion because it allows holders to avoid tax on gain when they sell stock of a qualified C‑corporation. The recently enacted One Big Beautiful Bill Act (OBBBA) makes this benefit even more attractive for new investments by shortening the holding period, increasing the gain cap and broadening the size of qualifying companies. However, these changes have led some holders of existing QSBS to wonder whether they can "refresh" or recapitalize their stock to take advantage of the new rules. The answer is generally no—and the consequences of getting it wrong can be severe.

What Changed Under the OBBBA

On July 4 2025 President Trump signed the OBBBA into law. Three distinctions matter for existing QSBS:

• Exclusion percentages and the dollar-limit regime follow the shareholder's statutory acquisition date, including applicable holding-period tacking. Stock acquired on or before July 4, 2025 remains subject to the earlier rules (generally more than five years, with a 100% exclusion for qualifying stock acquired after September 27, 2010 through July 4, 2025; earlier acquisitions generally use the historical 50% or 75% regimes, subject to special rules; the eligible-gain limit is the greater of the remaining $10 million dollar limit or 10× qualifying basis). Qualifying later acquisitions can use the three-, four- and five-year tiers (50%/75%/100%) and the $15 million dollar limit, with applicable indexing.
• The gross-assets ceiling follows issuance: $50 million for stock issued on or before July 4, 2025, and $75 million for later issuances, with applicable indexing. Issuance and statutory acquisition are separate tests.
• Conversions and qualifying reorganizations do not create a new-regime election. Section 1202(f) can preserve QSBS on a conversion solely into another class of stock in the same corporation. Section 1202(h)(4) can preserve treatment in qualifying §351 exchanges and §368 reorganizations, subject to its conditions and limitations. These provisions carry forward the relevant holding period rather than moving older shares into the post–July 4, 2025 exclusion regime.

None of this is retroactive. Section 1202(a)(5), added by the OBBBA, applies the tiered 50/75/100 % exclusion only to stock acquired after the "applicable date" — July 4, 2025 — with the acquisition date determined after applicable tacking under §1202(a)(6)(B). The $15 million cap follows the same acquisition line; the $75 million gross-asset ceiling follows the issuance date. Stock issued on or before that date stays under the pre-act rules for the gross-assets ceiling; stock acquired on or before that date (after tacking) stays under the pre-act exclusion and dollar-limit rules.

The Original‑Issuance Requirement Still Rules

Section 1202 only applies to stock that is acquired directly from the corporation in exchange for cash, property (other than stock), or services. This is often called the original‑issuance requirement. A secondary purchase from another shareholder does not qualify because the buyer did not acquire the stock from the corporation. Likewise, "refreshing" your QSBS by exchanging it for newly issued shares can destroy QSBS status if the exchange does not fall into one of the statute's narrow exceptions.

Exchanges, Reorganizations and "Refreshing" Stock

Conversions within the same corporation. When QSBS is converted into a different class of stock in the same corporation—such as exchanging common stock for preferred stock—Section 1202(f) can treat the new shares as QSBS acquired on the date the exchanged shares were originally issued. The holding period is tacked, meaning the clock does not restart and the shares do not automatically enter the post–July 4, 2025 exclusion regime.

Tax‑free reorganizations or Section 351 exchanges. Section 1202(h)(4) provides that if QSBS is exchanged for stock of another corporation in a Section 351 nonrecognition exchange or a tax‑free reorganization described in Section 368, the stock received will be treated as QSBS. The successor stock is deemed acquired on the date the surrendered QSBS was originally issued, so the holding period from the old shares carries over. The rule is subject to important limitations: If your company was acquired in a stock-for-stock deal, see what happens to your QSBS after an acquisition — including the exchange-date cap on how much of your gain remains excludable.

• Successor-stock limitation. When §1202(h)(4) preserves QSBS treatment, the exclusion generally cannot exceed the gain that would have been recognized at the exchange if §351 or §368 had not applied. That particular limitation does not apply when the issuer of the replacement stock is a qualified small business at the time of the exchange. Other applicable requirements still matter; qualification at closing is not a guarantee that every dollar of later appreciation will be excluded.
• Control requirement for Section 351. Section 351 generally requires the property transferors, as a group, to control the transferee corporation immediately after the exchange. Separately, Section 1202(h)(4)(D) requires the corporation issuing the replacement shares to own, directly or indirectly, control of the corporation whose QSBS was exchanged immediately after the transaction. These are different ownership relationships. If Section 351 does not apply, check whether another nonrecognition provision applies. If the exchange is taxable, gain on the old QSBS may still qualify for Section 1202 exclusion; the status of the replacement shares is a separate question. See §351(a) and §1202(h)(4)(D).

What happens if the exchange is not tax‑free? A taxable exchange can trigger gain on your existing QSBS that remains eligible for Section 1202 exclusion, subject to the applicable holding period, eligible-gain limit, exclusion percentage and other requirements. Section 1202 covers gain from a sale or exchange. The replacement shares generally will not qualify as QSBS when received in exchange for stock without an applicable exception. Analyze the gain on the old shares separately from the status of the new shares. For example, if you exchange qualifying old shares with $1 million basis for buyer shares worth $6 million in a fully taxable exchange, your $5 million gain may be excludable if all Section 1202 requirements are met, even though the buyer shares you receive generally are not QSBS. See §1202(a) and (c).

You Can't "Reset" the Clock

Even when an exchange qualifies under Section 351 or Section 368, the new stock inherits the holding period of the old QSBS. You cannot exchange five‑year‑old QSBS into new shares and move into the OBBBA's shorter three‑year tier or the higher $15 million dollar limit solely by virtue of the exchange. The exclusion and dollar-limit regime follow the statutory acquisition date after applicable tacking; the gross-assets ceiling follows issuance. Identify which rule applies before treating a recapitalization as either a tax benefit or a disqualification.

Takeaways for Founders and Investors

1. Keep the three distinctions straight. Exclusion percentages and the dollar-limit regime follow the shareholder's statutory acquisition date, including applicable holding-period tacking. Stock acquired on or before July 4, 2025 remains subject to the earlier rules; qualifying later acquisitions can use the three-, four- and five-year tiers. The gross-assets ceiling follows issuance: $50 million on or before July 4, 2025, and $75 million thereafter, with applicable indexing. Section 1202(f) and §1202(h)(4) can preserve QSBS and carry forward the relevant holding period; they do not supply a new-regime election.
2. Do not attempt to "refresh" QSBS without careful tax planning. The original‑issuance requirement means that exchanging QSBS for new shares generally disqualifies the stock unless the transaction fits within Section 1202(f), Section 351, or Section 368. Even when it does, the holding period carries over.
3. Apply the successor-stock limitation correctly. When §1202(h)(4) preserves QSBS treatment, the exclusion generally cannot exceed the gain that would have been recognized at the exchange if §351 or §368 had not applied — unless the issuer of the replacement stock is a qualified small business at the time of the exchange. Qualification at closing is not a guarantee that every dollar of later appreciation will be excluded.
4. Seek professional advice. QSBS planning has become more attractive under the OBBBA, but it remains technical. Missteps in corporate restructurings, recapitalizations or estate planning can cost you the QSBS exclusion. Work with experienced tax counsel to evaluate any proposed transactions.

The QSBS exclusion is a powerful tool for founders and investors, but its benefits hinge on careful adherence to the statute. The OBBBA expands those benefits for new investments, yet a qualifying conversion or reorganization does not automatically move older shares into the post–July 4, 2025 exclusion regime. Before embarking on any restructuring, consult a knowledgeable tax advisor to ensure that your QSBS remains qualified and that you do not inadvertently give up a valuable exclusion.
