Whether a corporate buyback of your shares is taxed as a stock sale or as a dividend comes down to Section 302 of the Internal Revenue Code: if the redemption passes one of four tests, you get sale treatment and subtract your basis before paying tax on the gain; if it fails all four, the whole distribution is a dividend to the extent of the corporation’s earnings and profits, with no basis offset at the time of the payment. On a large buyback, that distinction routinely swings the tax bill by tens of thousands of dollars. Understanding the stock redemption sale vs. dividend tax treatment rules before the check is cut is what separates a clean exit from an expensive surprise.
Why the Characterization Matters in Dollars
Under sale treatment, the math is familiar: proceeds minus adjusted basis equals gain, and if the shares were held more than a year, the long-term capital gains rate applies (topping out at 20% for 2026).1Office of the Law Revision Counsel. 26 U.S. Code 302 – Distributions in Redemption of Stock
Under dividend treatment, the distribution is governed by Section 301. The portion covered by the corporation’s earnings and profits (E&P) is a dividend.2Office of the Law Revision Counsel. 26 U.S. Code 301 – Distributions of Property For a qualified shareholder in a domestic C corporation, that dividend can be taxed at the same preferential rates as long-term capital gains, so the rate itself may not change dramatically. The bite comes from basis. A shareholder who paid $200,000 for stock and receives $500,000 in a failed redemption owes tax on the full $500,000 (up to E&P), not on the $300,000 economic gain. Basis in the redeemed shares does not disappear, but it isn’t recovered at the time of the redemption.
The Four Tests for Sale Treatment
Section 302(b) sets out four ways a redemption qualifies as a sale or exchange. Each test asks, in a different way, whether the redemption genuinely reduced the shareholder’s stake or merely dressed up a dividend as a buyback.1Office of the Law Revision Counsel. 26 U.S. Code 302 – Distributions in Redemption of Stock
Not Essentially Equivalent to a Dividend
This is a facts-and-circumstances test with no numerical threshold. The Supreme Court held in United States v. Davis that a redemption qualifies only if it produces a “meaningful reduction of the shareholder’s proportionate interest in the corporation.”3Justia Law. United States v. Davis, 397 U.S. 301 (1970) Courts weigh changes in voting power, rights to earnings, and rights to net assets on liquidation. A shareholder dropping from control to a minority position has a strong argument; a sole shareholder whose constructive ownership stays at 100% has none. Because the test is subjective, advisors usually prefer the mechanical routes.
Substantially Disproportionate Redemption
The workhorse test. It requires three conditions immediately after the redemption, all of them:
- The shareholder owns less than 50% of the total combined voting power of all voting classes.
- The shareholder’s percentage of voting stock after the redemption is less than 80% of what it was before.
- The same 80% reduction applies to the shareholder’s ownership of all common stock, voting and nonvoting combined.
Miss any one and the test fails. In practice, the 80% reduction is where most closely held redemptions come apart.
Complete Termination of Interest
If the corporation redeems every share the shareholder owns, sale treatment is automatic. The important feature of this test is that it lets the shareholder waive the family attribution rules under Section 318, which is often the only way a “complete” termination is actually complete on paper.
To waive family attribution, the former shareholder must: retain no interest in the corporation other than as a creditor (no officer, director, or employee role); acquire no such interest for 10 years after the redemption, other than stock received by inheritance; and file a written agreement with the IRS to report any prohibited acquisition during that 10-year window. The 10-year commitment is the price of ignoring family ownership.
Partial Liquidation
Available only to non-corporate shareholders. The distribution must not be essentially equivalent to a dividend at the corporate level and must occur under a plan adopted in the same taxable year or the next. The typical fact pattern: a corporation that has run at least two active businesses for five or more years terminates one and continues the other. Unlike the other three tests, this one focuses on what happened at the corporate level, not on shifts in the individual’s percentage.
Constructive Ownership Is Usually What Kills Sale Treatment
Before any of the four tests can be applied, Section 318 makes you count stock you don’t actually hold. You are treated as owning shares held by certain family members and by certain entities you are connected to.4Office of the Law Revision Counsel. 26 U.S. Code 318 – Constructive Ownership of Stock In a closely held corporation, this is nearly always the reason a redemption that looks like a sale gets taxed as a dividend.
Family attribution covers a spouse, children, grandchildren, and parents. Siblings are not on the list. Stock a person constructively owns only through family attribution cannot be reattributed sideways from that person to another family member. Attribution also flows between entities and their owners: partnership and estate stock is attributed proportionately to partners and beneficiaries and back the other way in full; corporate attribution runs in both directions only when the shareholder holds 50% or more of the corporation by value; and an option to acquire stock is treated as ownership.
A Worked Example: When the 80% Test Fails
Alpha Corp is a closely held C corporation with 1,000 shares of common voting stock outstanding and substantial accumulated E&P. The shareholders:
- Shareholder A owns 300 shares (30%). A is the mother of Shareholder B.
- Shareholder B owns 200 shares (20%). B is A’s son.
- Shareholder C owns 500 shares (50%). C is unrelated.
A wants to scale back and has Alpha Corp redeem 150 of her 300 shares for $450,000. Her basis in those 150 shares is $100,000. Sale treatment would put $350,000 of gain on her return. Dividend treatment would put $450,000 of dividend income there.
Before
A directly holds 300 of 1,000 shares. Family attribution adds B’s 200 shares. A’s constructive ownership is 500 out of 1,000, or 50.0%.
After
The 150 redeemed shares are retired, so 850 shares remain outstanding. A directly holds 150. B still holds 200; C still holds 500. With attribution, A constructively owns 350 out of 850, or 41.18%.
Running the Substantially Disproportionate Test
- 50% voting power: A is at 41.18% post-redemption, which is below 50%. Passes.
- 80% voting stock: A’s pre-redemption percentage was 50.0%. Multiplied by 80%, the target is 40.0%. A’s post-redemption 41.18% is not below 40.0%. Fails.
Because one condition fails, the substantially disproportionate test fails. Complete termination is unavailable (A still holds 150 shares). A could try to argue “not essentially equivalent to a dividend” on the drop from 50% to 41.18%, but that outcome is uncertain. The $450,000 defaults to dividend treatment to the extent of Alpha Corp’s E&P, with no basis offset.
What A Should Have Done Instead
A needed post-redemption constructive ownership below 40.0%. Redeeming 200 shares instead of 150 gets her there: 800 shares outstanding, A directly holds 100, plus B’s 200 attributed, for 300 out of 800, or 37.5%. That clears 40.0% and stays under 50%, so all three prongs pass. Alternatively, if A wanted out entirely, redeeming all 300 of her shares and filing the waiver of family attribution would give her sale treatment on the whole exit, at the cost of a 10-year separation from Alpha Corp.
What Happens to Your Basis if It’s a Dividend
When a redemption is recharacterized as a dividend, basis in the redeemed shares is not lost. It shifts to the shareholder’s remaining shares in the same corporation.5eCFR. 26 CFR 1.302-2 – Redemptions Not Taxable as Dividends In the Alpha example, A’s $100,000 basis in the redeemed 150 shares would move to her remaining 150 shares. If a shareholder has all of their shares redeemed but still lands in dividend treatment because of family attribution, the basis shifts to the related party whose shares were attributed, and recovery depends on what that person eventually does with the stock.
Two Situations Worth Knowing About
Estates Redeeming Stock to Pay Death Taxes
Section 303 provides an escape from the Section 302 tests for estates with concentrated business wealth. If the decedent’s stock in a corporation exceeds 35% of the adjusted gross estate (gross estate less deductions under Sections 2053 and 2054), the estate can redeem enough stock to cover estate and inheritance taxes plus allowable funeral and administration expenses and receive automatic sale or exchange treatment on that amount.6Office of the Law Revision Counsel. 26 USC 303 – Distributions in Redemption of Stock to Pay Death Taxes Anything the estate takes above that amount falls back to the standard Section 302 analysis.
Paying the Redemption With Appreciated Property
Cash redemptions don’t trigger gain at the corporate level. Property redemptions do. Under Section 311(b), a corporation distributing appreciated property is treated as if it sold the property to the shareholder at fair market value and must recognize the gain.7Office of the Law Revision Counsel. 26 USC 311 – Taxability of Corporation on Distribution Real estate with a $200,000 basis and a $600,000 fair market value used to fund a buyback produces $400,000 of corporate gain, even though no third-party sale occurred.
Don’t Forget the 3.8% Net Investment Income Tax
Whether the redemption ends up as capital gain or as a dividend, the proceeds are net investment income. The 3.8% NIIT applies to individuals with modified adjusted gross income over $200,000 (single), $250,000 (married filing jointly), or $125,000 (married filing separately). Estates and trusts hit the threshold at roughly $16,000 for 2026.8Internal Revenue Service. Topic No. 559, Net Investment Income Tax On a $450,000 redemption, the surcharge alone can exceed $13,000. It applies either way, so it doesn’t influence the sale-versus-dividend analysis, but it adds to the total cost.
Reporting
The corporation reports a redemption treated as a dividend on Form 1099-DIV.9Internal Revenue Service. About Form 1099-DIV, Dividends and Distributions A redemption treated as a sale is generally reported on Form 1099-B, and the shareholder reports the capital gain on Schedule D. A shareholder who waives family attribution under the complete termination rules must attach the written agreement to the return for the year of the redemption. Missing that filing, or reacquiring a prohibited interest inside the 10-year window, can retroactively convert the sale into a dividend and produce underpayment penalties and interest on top of the new tax.
