THE SHORT ANSWER
QSBS is a potential federal exclusion for gain on qualifying stock, not a tax-free sale rule for every small business. The July 4, 2025 law changed certain holding periods and limits for stock acquired after enactment. Entity, issuance, acquisition, activity and holding-period facts matter. Do not assume a 2026 sale qualifies for the new rules.
The dates determine which changes can apply
Section 70431 of Public Law 119-21 was enacted July 4, 2025. For qualifying stock acquired after that date, the phased exclusion is 50% at three years, 75% at four years and 100% at five years or more. The new base dollar limitation is $15 million, subject to the statute’s per-issuer rules and reductions; the alternative basis-based limit and other conditions require separate analysis.
(Public Law 119-21, section 70431)Earlier stock does not acquire the new three-year schedule merely because it is sold in 2026. Acquisition dates can depend on holding-period rules; they are not always the date on a newly printed certificate. A new purchase after July 4, 2025 generally cannot complete a three-year period during 2026.
Check the company and the issuance
The IRS describes qualifying stock requirements including a domestic C corporation, original issuance and qualified-business conditions. Its instructions identify a $75 million gross-asset threshold for stock issued after July 4, 2025, versus $50 million for earlier issuance.
(IRS: Schedule D instructions, QSB stock)These are gross-asset tests, not annual-revenue ceilings. Acquisition date for the shareholder and issuance date for the company answer different questions. A corporation’s tax history, predecessor assets, redemptions and activity can also matter. Not all business activities qualify.
An LLC interest or S-corporation share is not automatically QSBS. Changing an entity classification shortly before sale does not establish that the requirements or holding period have been satisfied.
Assemble an eligibility file before quoting a savings amount
| Evidence to organize | Question for the tax advisor |
|---|---|
| Formation and tax-election history | Was the issuer the required type of corporation? |
| Subscription and issuance records | Was the stock acquired at original issue or through a qualifying exception? |
| Acquisition dates and transfers | Which holding period and rules apply to this shareholder? |
| Historic and issuance-date asset records | Was the applicable gross-asset test satisfied? |
| Operating activity and asset use | Were qualified-business conditions maintained? |
| Prior exclusions and share basis | What issuer-level and basis-based limits remain? |
Obtain advice before restructuring, gifting shares or committing to a sale date. Do not treat trust planning or “stacking” as a standard guaranteed savings strategy.
Connect the stock analysis to the proposed deal
A corporation selling its operating assets is not the same transaction as a shareholder selling qualifying stock. Ask whether the buyer’s proposed structure produces the type of gain covered by the exclusion. State treatment and other tax consequences need their own review.
The dollar limit refers to eligible gain under specific rules, not an automatic $15 million of tax-free revenue, enterprise value or cash proceeds. The 2025 law provides inflation adjustment for certain amounts after 2026; use the amount applicable to the actual tax year rather than assuming today’s base figure will remain unchanged.
Use the asset-versus-equity planning guide to assemble the transaction facts. A tax advisor should determine eligibility and liability; the proceeds tool only subtracts a reserve you supply.
Owner questions
Does selling in 2026 make my gain eligible for the $15 million limit?
No. The stock acquisition date, issuer facts and other statutory conditions control. The year of sale alone is insufficient.
Does the new three-year schedule apply to all existing stock?
No. The July 2025 changes distinguish stock acquired after enactment from earlier acquisitions, subject to the holding-period rules.
Does a $15 million sale mean $15 million is excluded?
No. Eligible gain, tax basis, the issuer limits, prior exclusions and the transaction structure must be analyzed.
