Summary

The OBBBA’s shorter holding periods and larger caps apply only to stock acquired after July 4, 2025. Exchanging or recapitalizing existing QSBS to “refresh” it can disqualify the stock, and the holding period cannot be reset.

The One Big Beautiful Bill Act (OBBBA) expanded the QSBS exclusion, but the shorter holding periods and larger cap reach only stock acquired after July 4 2025. Trying to “refresh” existing QSBS by recapitalization or exchanging shares can disqualify your stock because QSBS requires original issuance and the holding period cannot be reset.

The OBBBA’s shorter holding periods and higher exclusion cap reach only stock acquired after July 4, 2025, acquisition determined after applicable holding-period tacking; the raised gross-assets ceiling separately follows the issuance date.
QSBS must be acquired at original issuance; exchanging or recapitalizing stock to “refresh” it generally disqualifies the stock from QSBS benefits.
Section 351 contributions and Section 368 reorganizations may allow your original holding period to carry over, but they do not restart the clock or qualify for the new OBBBA benefits.
You cannot reset your five-year holding period; attempting to convert or reissue shares may void QSBS status, so hold your existing stock for the full period to claim the exclusion.
Before restructuring or taking advantage of new rules, consult experienced tax and legal advisors to ensure compliance and avoid disqualifying your QSBS.

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 caused 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.

This post is part of our Complete Guide to QSBS and Section 1202.

What Changed Under the OBBBA

On July 4 2025 President Trump signed the OBBBA into law. The statute introduced three major changes to Section 1202, all of which apply only to stock issued after the act’s effective date:

Shorter holding period – Under prior law, QSBS had to be held more than five years to exclude 100 % of the gain (subject to a cap). The OBBBA introduced a tiered schedule for stock acquired after July 4 2025: investors may exclude 50 % of gain when stock is held at least three years and less than four, 75 % of gain after four years and less than five, and 100 % after five years. Pre‑act stock must still be held for more than five years to claim any exclusion.
Larger company eligibility – Before the law, QSBS benefits applied only when the issuing corporation’s aggregate gross assets did not exceed $50 million. The OBBBA increased the threshold to $75 million, indexed for inflation. This expansion allows more late‑stage startups to issue QSBS, but it is effective only for stock issued after July 4 2025.
Higher exclusion cap – The per‑issuer gain cap increased from $10 million to $15 million, also indexed for inflation. The alternative cap of ten times the taxpayer’s basis continues to apply. The larger cap likewise applies only to stock acquired after July 4 2025.

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: more than five years, a $10 million (or 10× basis) cap, and a $50 million ceiling.

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—the new shares are treated as QSBS and are considered acquired on the date the exchanged shares were originally issued. The holding period is tacked, meaning the clock does not restart.

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 must be a qualified small business. If the acquiring corporation qualifies as a small business (i.e., its gross assets, including those of the target, are below the applicable threshold and it meets the active trade‑or‑business requirement), all the successor shares are QSBS and future appreciation is eligible for exclusion. If the successor corporation is not a qualified small business, only the built‑in gain on the exchanged QSBS is eligible; any post‑transaction appreciation will not be excludable.
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 magically restart the holding period under the OBBBA’s shorter three‑year rule. Similarly, you cannot switch to the higher $15 million cap by rolling your old QSBS into new shares. The OBBBA expressly states that the shorter holding periods and larger caps apply only to stock acquired after July 4 2025, and any tacked holding period rules must be taken into account. Attempting to engineer a new issuance or recapitalization to “refresh” your QSBS could therefore backfire, either by disqualifying the stock or by leaving you stuck with the old regime.

Takeaways for Founders and Investors

Understand the cutoff. QSBS acquired after July 4 2025 is subject to the OBBBA’s shorter holding periods, higher gain caps and expanded eligibility thresholds. Stock issued on or before July 4 2025 remains subject to the pre‑act five‑year holding period and $10 million gain cap.
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 351 or Section 368. Even when it does, the holding period carries over.
Beware of successor company qualifications. In tax‑free reorganizations, the successor corporation must itself be a qualified small business for the new stock to receive full QSBS treatment.
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 cause you to lose 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 it does not provide a shortcut for existing stock. 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.
