When a corporation buys back stock from one of its owners, it feels like a simple sale. The shareholder hands over shares, the company hands over cash, everyone moves on. The tax code does not see it that way. Under Section 302, that same transaction can be treated as a clean sale that produces a capital gain, or as a dividend that gets taxed very differently, and which one you land on depends on a set of tests that catch a lot of people by surprise.
Here is the short version. A distribution in redemption of stock is treated as a sale or exchange, giving the shareholder capital gain treatment, only if it meets one of the tests in Section 302(b). If it fails all of them, the payment is treated as a Section 301 distribution, which usually means a dividend. The difference is not just the rate. Sale treatment lets the shareholder recover their stock basis and pay tax only on the gain, while dividend treatment can tax the whole amount.
This guide walks through what a redemption is, why the sale-versus-dividend question matters, the four tests that earn capital gain treatment, the constructive ownership rules that quietly sink many redemptions, and what happens when a redemption fails. This is general information rather than tax advice, so consult a tax adviser for any specific deal.
A redemption happens when a corporation acquires its own stock from a shareholder in exchange for cash or other property. The whole question under Section 302, which the code titles distributions in redemption of stock, is how to tax what the shareholder receives, and there are only two answers.
The first is sale or exchange treatment under Section 302(a). Here the redemption is treated as a sale of the shares back to the distributing corporation. The owner subtracts their stock basis, and only the excess is gain, generally taxed as a capital gain. The second is distribution treatment under Section 302(d), which routes the payment through Section 301. That makes it a dividend to the extent of the corporation's earnings and profits, with no basis offset against the distribution, then a return of capital, then capital gain.
Why does the difference matter so much? For an individual, qualified dividends and long-term capital gains often carry the same tax rate, so the headline rate can look identical. The real advantage of sale treatment is basis recovery. If a shareholder redeems stock for $100,000 and has $70,000 of basis, capital gain treatment taxes only the $30,000 of gain, while a full dividend can tax the entire $100,000. The answer can flip for a corporate shareholder, which may actually prefer a dividend because of the dividends-received deduction. Knowing which side you want is the starting point, and it is one reason the choice between a C corp and an S corp shapes so much downstream.
The cleanest path to capital gain treatment is Section 302(b)(2), the substantially disproportionate test, because it is mechanical. If you hit the numbers, you qualify, no judgment call required. A redemption is substantially disproportionate when all three of these are true immediately after the redemption:
An example makes it click. Say a corporation has 1,000 voting common shares held by five unrelated shareholders, 200 each, so everyone owns 20%. The corporation redeems 150 shares from A, 75 from B, and 25 from C, leaving 750 shares outstanding. A now owns 50 shares, or about 6.7%. A's post-redemption ownership is less than 80% of the old 20% stake, which was 16%, and it is well under 50%, so A gets capital gain treatment. B, now at about 16.7%, just misses the 16% ceiling and fails. C actually rises to about 23%, so C fails too. Same transaction, three different tax answers, all driven by the math.
Section 302(b)(3) is the most intuitive test: if the corporation redeems all of the stock the shareholder owns, the redemption qualifies as a sale or exchange. An owner who fully exits should not be treated as receiving a dividend, and usually is not.
The complication is that ownership here includes shares the shareholder is treated as owning through family members, which we will get to in a moment. A parent redeeming all of their own shares can still be treated as owning a child's shares, which means the redemption is not actually complete. Section 302(c)(2) offers a way out through a family attribution waiver, but it comes with conditions. The redeemed shareholder must keep no interest in the corporation other than as a creditor, must not acquire an interest other than by bequest or inheritance within 10 years, and must file the required agreement with the IRS. Handled correctly, the waiver lets a genuine exit qualify even in a closely held family business.
Section 302(b)(1) is the catch-all, and it is the hardest to rely on because it has no formula. A redemption qualifies if it is not essentially equivalent to a dividend, which the courts have read to require a meaningful reduction in the shareholder's proportionate interest in the corporation. That reduction is measured across voting power, the right to share in earnings, and the right to share in net assets on liquidation.
This test tends to matter for a minority owner whose redemption does not clear the 80% threshold of the substantially disproportionate test but still gives up real ground, such as losing the ability to block corporate actions. It cannot help a sole shareholder, because someone who still owns 100% after the redemption has not reduced anything. Because the standard is judgment based on facts and circumstances, it is the test practitioners reach for last, and document most carefully.
The fourth path, Section 302(b)(4), works differently from the others. A redemption from a noncorporate shareholder qualifies for sale or exchange treatment if it is made in partial liquidation of the distributing corporation. The key twist is that this test is applied at the corporate level, asking whether the distribution is not essentially equivalent to a dividend from the corporation's point of view, rather than looking only at the individual shareholder's percentage.
In practice, a partial liquidation of a corporation usually involves a genuine contraction of the business. The clearest safe harbor is a distribution attributable to the corporation ceasing to conduct one qualified trade or business, where the corporation continues to run at least one other trade or business that it has actively conducted throughout the preceding five years. Because it is tested at the entity level, this route can deliver capital gain treatment even for a pro rata redemption that would fail the shareholder-level tests.
Here is the rule that quietly derails more redemptions than any other. The percentage tests above are not based only on the shares a person holds in their own name. Under the Section 318 constructive ownership rules, a shareholder is treated as owning stock held by certain family members, such as a spouse, children, grandchildren, and parents, and stock held through related entities like partnerships, estates, trusts, and controlled corporations.
For a closely held company, this attribution is often the whole ballgame. Imagine a father who owns 60% of a family corporation and his daughter who owns the other 40%. If the corporation redeems enough of the father's shares that he directly holds only 30%, the mechanical test looks satisfied. But because he is treated as owning his daughter's 40% too, his real ownership stays high, and the redemption fails the tests and becomes a dividend. Running the Section 318 numbers before the deal, rather than after, is what separates a clean capital gain from an unwelcome surprise.
If a redemption clears none of the Section 302(b) tests, Section 302(d) treats it as a Section 301 distribution. That means it is a dividend to the extent of the corporation's earnings and profits, then a nontaxable return of capital against the shareholder's basis, then capital gain for anything beyond that. The shareholder gets no immediate basis recovery on the dividend portion, and the basis of the redeemed shares generally shifts to the shares the shareholder still holds rather than disappearing.
Two more points round this out. At the corporate level, paying cash in a redemption creates no gain or loss for the corporation, but distributing appreciated property does trigger corporate gain as if the property were sold. And for an S corporation, the analysis interacts with its accumulated adjustments account and any earnings and profits carried over from prior C corporation years, so redemptions at S corporations with significant AAA and old E&P need their own careful review.
The honest takeaway is that Section 302 is a testing exercise, and the tests are unforgiving. Running the substantially disproportionate math, applying Section 318 attribution correctly, confirming a complete redemption really is complete, testing a partial liquidation at the entity level, and then tracking basis and earnings and profits through the result is detailed work, and a single missed attribution can turn an expected capital gain into a fully taxable dividend.

What is a stock redemption under Section 302? A stock redemption is when a corporation acquires its own shares from a shareholder in exchange for cash or other property. Section 302 decides how the shareholder is taxed on what they receive. If the redemption meets one of the tests in Section 302(b), it is treated as a sale or exchange of the stock, producing capital gain. If it meets none of them, Section 302(d) treats the payment as a Section 301 distribution, which is usually a dividend.
Is a stock redemption taxed as a capital gain or a dividend? It depends on whether the redemption passes one of the four Section 302(b) tests. If it does, the shareholder gets sale or exchange treatment, recovers their stock basis, and pays tax only on the gain as a capital gain. If it fails all four, the distribution is treated as a dividend to the extent of the corporation's earnings and profits, generally with no basis offset. For individuals the rates can be similar, but basis recovery usually makes capital gain treatment the better outcome.
What is the substantially disproportionate test? It is the mechanical safe harbor in Section 302(b)(2). A redemption is substantially disproportionate if, immediately after it, the shareholder owns less than 50% of the total combined voting power, their voting stock percentage is less than 80% of what it was before, and the same 80% test is met for common stock. If all three conditions are satisfied, using the Section 318 attribution rules, the shareholder gets capital gain treatment.
What is a complete redemption? A complete redemption under Section 302(b)(3) is one in which the corporation redeems all of the stock the shareholder owns, which qualifies the redemption as a sale or exchange. The challenge is that ownership includes shares attributed from family members, so a redemption that looks complete may not be. Section 302(c)(2) allows a family attribution waiver if the shareholder keeps no interest other than as a creditor, acquires no new interest for 10 years except by inheritance, and files the required agreement.
What does not essentially equivalent to a dividend mean? Under Section 302(b)(1), a redemption qualifies for sale treatment if it is not essentially equivalent to a dividend, which the courts interpret as requiring a meaningful reduction in the shareholder's proportionate interest. That is measured by voting power, the right to share in earnings, and the right to share in assets on liquidation. It is a facts and circumstances test, most useful for a minority shareholder who loses real influence but does not meet the mechanical thresholds.
What are the Section 318 constructive ownership rules? Section 318 treats a shareholder as owning stock they do not hold directly, including shares owned by close family members such as a spouse, children, grandchildren, and parents, and shares held through partnerships, estates, trusts, and controlled corporations. These constructive ownership rules apply when running the redemption tests, and in closely held corporations they often cause a redemption that looks like a sale to be taxed as a dividend instead.
What happens if a redemption fails the Section 302 tests? If a redemption meets none of the Section 302(b) tests, Section 302(d) treats it as a Section 301 distribution. It is a dividend to the extent of the corporation's earnings and profits, then a return of capital against basis, then capital gain. The shareholder does not get basis recovery against the dividend portion, and the basis of the redeemed shares generally moves to their remaining shares rather than being lost.
