Qualified small business stock: how we think about the tiers

Qualified small business stock is the part of the Internal Revenue Code, § 1202, that can take a founder's gain on the sale of C corporation shares and exclude most or all of it from federal income tax. For years it was a footnote in Oklahoma, where so many closely held companies run as LLCs or S corporations and never issue C corporation stock at all. Pub. L. 119-21, enacted July 4, 2025, rewrote the rules for stock issued after that date, and the rewrite is generous enough that the question now belongs in the formation conversation, not only the exit conversation.

This is how we think about it: four moments in the life of a company where § 1202 is either won or lost, and what we weigh at each one. Everything below separates two regimes. "Old stock" means stock issued on or before July 4, 2025. "New stock" means stock issued after that date.

What the two regimes actually say

Old stock first, because a lot of it is still sitting in cap tables. Under § 1202(a)(4), stock acquired after September 27, 2010 and on or before July 4, 2025 gets a 100% exclusion if held more than five years. Earlier vintages get less: 75% for stock acquired after February 17, 2009 and on or before September 27, 2010, and 50% for stock acquired before that.

The per-issuer cap for old stock is the greater of $10,000,000 or ten times the aggregate adjusted basis of the stock in that issuer sold during the year. And the issuer had to stay at or under $50,000,000 of aggregate gross assets from August 10, 1993 through the issuance and immediately after it.

New stock changes three numbers and one clock. The holding period becomes a ladder: 50% of the gain excluded once the stock has been held three years, 75% at four years, 100% at five years or more. The dollar cap rises to $15,000,000 per issuer, still subject to the greater-of test against ten times basis. The gross-asset ceiling rises to $75,000,000, measured the same way.

Both the $15,000,000 cap and the $75,000,000 ceiling are indexed for inflation for taxable years beginning after 2026, using 2025 as the base year and rounding to the nearest $10,000. We don't compute the adjusted figures here. Check the current number in the year that matters.

Two wrinkles in the cap

Married taxpayers filing separate returns get half: $5,000,000 instead of $10,000,000 on old stock, and one-half of $15,000,000 on new stock. The halving follows the return, not the ownership, so a filing-status decision in the year of sale carries real money.

The second wrinkle is quieter. Under § 1202(b)(5)(B), once a taxpayer's eligible gain on new stock from a particular issuer exceeds the applicable dollar limit in a year, that taxpayer's limit for the same issuer in every later year is zero. Selling in slices across several years to pick up future inflation adjustments stops working the moment you blow through the cap.

Moment one: formation

Almost every § 1202 requirement is a test about the issuer, applied at or around the date the stock is issued. Section 1202(c)(1) requires stock in a C corporation, originally issued after August 10, 1993, acquired at original issue for money or property other than stock, or as compensation for services other than underwriting. A membership interest in an LLC taxed as a partnership isn't stock in a C corporation, and shares in an S corporation fail the same test.

So the first decision is whether to be a C corporation at all, and here is where we give the government-favorable side its airtime. A C corporation pays its own tax, and dividends to owners are taxed again. An Oklahoma company whose owners expect to pull profits out every year through distributions can lose more to that second layer over a five-year hold than the exclusion ever gives back.

Our rough frame: § 1202 rewards companies that reinvest and intend to sell, and penalizes companies that distribute. The company that fits is one with a product, outside capital on the horizon, and a plausible buyer. The company that doesn't fit is a profitable service firm paying out earnings each December, and for that owner the LLC-versus-S-corporation question still governs.

Formation also fixes the gross-asset number at its easiest point. Under § 1202(d)(2), aggregate gross assets means the corporation's cash plus the aggregate adjusted bases of its other property, with contributed property counted as if its basis equaled fair market value when contributed. A startup with a few hundred thousand dollars of cash clears $75,000,000 without thinking about it.

Here is an observation that only shows up when you have run the numbers for someone: the ceiling is a basis test, not a valuation test. A company that a venture investor values far above $75,000,000 can still issue qualifying stock if the basis of what it owns is low, while a company that received appreciated property from its founders counts that property at full fair market value and can fail the test on day one.

Moment two: converting an LLC to a C corporation

This is the path most Oklahoma companies would actually take, because they started as LLCs. A conversion generally means the members contribute their interests, or the LLC contributes its assets, to a corporation in exchange for stock. That stock is acquired at original issue for property, which is the kind of acquisition § 1202(c)(1) describes.

The holding period starts at the conversion, not at the date the LLC was formed. Under the old regime that meant five more years before any exclusion. Under the new tiers a three-year hold already buys a 50% exclusion, which changes the math for an owner who expects an exit in roughly four to six years.

Timing matters because the gross-asset test is applied at the conversion, with the contributed assets counted at fair market value. A company that has grown large before it converts can arrive at the conversion already over $75,000,000 and get nothing. The practical consequence is that the conversion decision has a window, and the window closes as the company succeeds.

Then the counter-considerations. The conversion has its own tax consequences, and the gain that accrued inside the LLC before the conversion is a separate question we always want examined before anyone celebrates the future exclusion. The owners also give up pass-through treatment permanently, and § 1202(c)(2)(A) requires the issuer to remain a C corporation during substantially all of the taxpayer's holding period, so an S election later undoes the work. We cover the mechanics of the move itself in our entity conversion article.

Moment three: a financing round

Each new investor who pays cash for newly issued shares starts a separate holding period and gets a separate per-issuer cap. The founders' clock keeps running on their own shares. That is why we treat every round as its own § 1202 event rather than something the company qualified for once at formation.

The gross-asset test bites here in a way that surprises people. Section 1202(d)(1)(B) measures aggregate gross assets immediately after the issuance, counting the amounts received in the issuance. A round that pushes the company past $75,000,000 means the shares issued in that round don't qualify, even though earlier rounds already issued keep their status.

The redemption traps

Section 1202(c)(3) disqualifies stock when the issuer has been buying back its own shares around the issuance date. Under (c)(3)(A), stock is out if the corporation purchased stock from the taxpayer or a related person during the four-year period beginning two years before the issuance. Under (c)(3)(B), stock is out if the corporation made purchases exceeding 5% of the aggregate value of all its stock during the two-year period beginning one year before the issuance, and (c)(3)(C) sweeps in transactions treated as redemptions under § 304(a).

The order things happen in is what gets companies hurt. A departing co-founder is bought out, the company raises a round six months later, and the new money arrives in shares that may already be tainted by the buyout. We would rather see the buyout question raised before the term sheet than discovered in the buyer's diligence years later.

Preferred stock that converts to common keeps its history. Under § 1202(f), stock acquired solely through the conversion of other qualified small business stock is treated as qualified and as held for the period the converted stock was held. The 80%-by-value active business test in § 1202(e)(1)(A) keeps running through the holding period, though, and a company holding a large cash balance after a round is a fact we would want reviewed against that test rather than assumed away.

Moment four: the exit

Section 1202 is a stock seller's benefit. If the corporation sells its assets and distributes the proceeds, the gain is the corporation's, taxed at the corporate level, and the shareholders' exclusion never comes into play. Buyers, as we explain in our article on the tax bill when you sell, usually prefer asset deals for their own reasons, so the exclusion often becomes a negotiating point in deal structure rather than a given.

For new stock the tiers change the timing conversation. Selling once the three-year mark is reached captures 50%. Waiting another year captures 75%, and another year after that captures everything. Nobody can promise the buyer will still be there in year five, and a founder weighing a strong offer at year three is making a real trade, not a mistake.

The greater-of rule in § 1202(b)(1) splits sellers into two camps. Founders with nominal basis live under the dollar cap, $10,000,000 for old stock and $15,000,000 for new stock, reduced by eligible gain they have already taken on the same issuer in prior years. Later investors with substantial basis may do better under ten times basis, which has no fixed ceiling. Both measures are per issuer, per taxpayer, which is one reason share ownership gets spread across family members and trusts before an exit, subject to its own rules that we won't pretend to cover here.

Reporting what you excluded

Schedule D's instructions for Form 1040 direct a seller to report the sale in Part II of Form 8949 as though there were no exclusion, enter code "Q" in column (f), and enter the excluded gain as a negative number in column (g). The same instructions can send a seller who reported a § 1202 exclusion through the 28% Rate Gain Worksheet, and the amount entered there depends on the exclusion percentage. That worksheet is the CPA's territory, and the arithmetic there is exactly the sort of thing we would want a return preparer and counsel to walk through together.

One honest caution on the instructions: the published Schedule D text still describes the exclusion in terms of the pre-July 4, 2025 rules, including the more-than-five-year holding period. Treat the statute as the law and the instructions as the reporting mechanics until the IRS updates them.

The Oklahoma question is a separate question

Oklahoma's income tax computation generally begins with federal figures, but that does not settle how a federal exclusion flows through to the Oklahoma return. The state has its own capital gain deduction with its own holding-period and ownership tests, and we would run a sale of qualified small business stock through the Oklahoma capital gain deduction rules rather than assume the federal result carries over. Sometimes the two provisions stack. Sometimes they don't. The answer depends on facts we can't state in the abstract.

Where qualified small business stock status is lost

The exclusion is rarely lost at the exit. It's lost quietly years earlier: a redemption to clear out a co-founder, a conversion that happened after the company got big, an asset mix that drifted away from the 80% test, a round that crossed the ceiling. Nobody checks until a buyer's counsel asks for the § 1202 analysis or a CPA preparing the return asks for the issuance-date balance sheet.

Section 1202(d)(1)(C) also requires the issuer to agree to submit whatever reports the Secretary requires, and the practical version of that promise is documentation. The cap table at each issuance, the balance sheet immediately before and after, the valuation of any contributed property, the board minutes for every repurchase. Those records are cheap to make in year one and nearly impossible to reconstruct in year six.

Can a well-run company lose the exclusion without anyone doing anything wrong? Yes, and that is the point of thinking about § 1202 as four moments rather than one. A qualification that depends on tests applied at issuance, through the holding period, and at the sale needs someone watching all three stretches of road.

When a lawyer is cheaper than the mistake

At formation, the cost of structuring for § 1202 is modest and the decision is mostly about whether a C corporation fits the owners' plans for distributions. At a conversion, the stakes are the pre-conversion gain and the gross-asset test, and the timing is usually tighter than owners realize. At a financing or a buyout, the redemption windows run two years in either direction, which is long enough to catch a transaction nobody connected to the stock. At the exit, the exclusion is worth a specific dollar amount that can be computed, and that number usually justifies the review.

If your Oklahoma company is weighing a C corporation, planning a conversion, taking in outside money, or heading toward a sale, that is a good moment to reach us through the contact page or our Oklahoma City office. The qualification questions are easier to answer while the facts are still being chosen, and a conversation early is almost always cheaper than discovering in diligence that the stock stopped qualifying years ago.
