When a closely held corporation buys back a shareholder’s stock, the IRS treats the payment as either a sale of the shares or as a corporate distribution, and the difference can cost real money. A closely held corporation stock redemption qualifies as a sale if it passes at least one of the four tests in Section 302 of the Internal Revenue Code. Pass one test and you recover your stock basis tax-free and pay capital gains rates only on the profit. Fail all four and the entire payment is treated as a distribution under Section 301, which usually means a bigger tax bill because your basis no longer offsets what you receive.
What Sale Treatment Actually Saves You
Under sale treatment, you subtract your adjusted basis from the redemption proceeds and pay tax only on the gain. Receive $200,000 for stock with a $40,000 basis and you report $160,000 of long-term capital gain. For 2026, long-term capital gains rates run 0%, 15%, or 20% depending on taxable income, with the 20% rate kicking in above $545,500 for single filers and $613,700 for joint filers.1Internal Revenue Service. Topic No. 409, Capital Gains and Losses High earners may also owe the 3.8% Net Investment Income Tax once modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly).2Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
Distribution treatment reclassifies the entire payment under Section 301.3Office of the Law Revision Counsel. 26 U.S. Code 301 – Distributions of Property To the extent the corporation has current or accumulated earnings and profits (E&P), that payment is a dividend. Here’s the part shareholders often miss: for an individual receiving dividends from a C corporation, those qualified dividends generally get the same 0%, 15%, or 20% preferential rates as long-term capital gains. The headline rate is often identical.
The real damage from failing Section 302 is losing basis recovery. In the example above, the full $200,000 becomes taxable as a dividend if the corporation has enough E&P, and your $40,000 basis does nothing to reduce that amount. The unrecovered basis shifts to any shares you still hold. If the redemption cleaned out your direct holdings but was still treated as a dividend because of constructive ownership, the basis moves to the shares of the related person whose stock was attributed to you.4GovInfo. 26 CFR 1.302-2 – Redemptions Not Taxable as Dividends
The math can flip for a corporate shareholder. A C corporation that receives dividend treatment on a failed redemption may claim a dividends-received deduction sheltering 50% to 100% of the payment depending on its ownership stake, sometimes producing a lower bill than sale treatment. That is why the IRS pays attention to the classification in both directions.
Attribution Rules Come First
Before you can run any of the four tests, you have to know what percentage of the corporation you own, and the IRS counts far more than the shares registered to you. Section 318 attributes stock ownership from family members, entities, and option holders, and its rules apply automatically before every Section 302 test.5Office of the Law Revision Counsel. 26 U.S. Code 318 – Constructive Ownership of Stock
Family attribution is where most closely held redemptions get into trouble. You are treated as owning all stock held by your spouse, children, grandchildren, and parents. The rules do not reach sideways: siblings, aunts, uncles, nieces, and nephews are excluded. A father who sells every share he directly owns back to the company still constructively owns his daughter’s shares, which can block a complete termination.
Entity attribution moves stock through partnerships, estates, trusts, and corporations. Shares held by a partnership or estate are treated as owned proportionately by the partners or beneficiaries, and the reverse is also true. For corporations, stock is attributed to a shareholder only when that shareholder owns 50% or more of the corporation’s value, and then only in proportion to their stake. S corporations are treated as partnerships for attribution purposes, so every S corp shareholder receives proportionate attribution regardless of size.
Option attribution treats an option holder as already owning the underlying stock, and chained options count too: an option to acquire an option counts as direct ownership.
Attribution can chain, but with limits. Stock you constructively own through entity or option rules is treated as actually owned for the next round of attribution. Stock attributed through the family rules cannot be re-attributed through the family rules a second time. Your father’s shares get attributed to you, but they do not then jump from you to your spouse. When both family and option rules could pick up the same stock, the option rule wins, which matters because option-attributed stock keeps chaining while family-attributed stock hits the re-attribution block.
The Four Section 302 Tests
A redemption qualifies as a sale if it passes any one of four tests in Section 302(b).6Office of the Law Revision Counsel. 26 U.S. Code 302 – Distributions in Redemption of Stock Passing one is enough. The tests range from mechanical bright-line rules to subjective judgment calls.
Substantially Disproportionate Redemption
The bright-line test in Section 302(b)(2) is the one most planners aim for. Immediately after the redemption, the shareholder must own less than 50% of the total combined voting power of all voting stock. And the shareholder’s voting-stock percentage after must be less than 80% of what it was before.7eCFR. 26 CFR 1.302-3 – Substantially Disproportionate Redemption Both requirements have to be met.
If you own 60% before, you need to drop below 48% after (60% × 80%), and you need to clear the absolute 50% ceiling. Start at 45% and you need to fall below 36%, with the ceiling already handled. The percentages use constructive ownership, not just the shares in your name, which is where the arithmetic usually goes wrong.
Complete Termination of Interest
Under Section 302(b)(3), the corporation redeems every share you actually and constructively own. This is the cleanest route to sale treatment, and it comes with a valuable option: you can waive family attribution. Without the waiver, a retiring parent who sells every direct share would still constructively own the children’s stock and fail the test outright.
The waiver has strict conditions. Immediately after the redemption you can hold no interest in the corporation other than as a creditor. No officer, director, or employee role. You must agree to notify the IRS within 30 days if you reacquire any interest within ten years, and you must keep records for the full ten years.8Internal Revenue Service. Private Letter Ruling 202219011 Break the ten-year rule and the IRS can go back and recharacterize the original redemption as a dividend.
The waiver statement must be attached to your timely filed return for the year of the redemption. There is no retroactive fix if you file without it.
Not Essentially Equivalent to a Dividend
The subjective catch-all in Section 302(b)(1) is the least predictable of the four. The Supreme Court held in United States v. Davis that a redemption qualifies only when it produces a “meaningful reduction” in the shareholder’s proportionate interest.9Justia Law. United States v. Davis, 397 U.S. 301 (1970) Courts look at voting power, the right to share in current earnings, and the right to assets on liquidation.
The standard has bite when the shareholder crosses a control threshold. A drop from 51% to 49% of the vote is the textbook example: losing majority control genuinely changes the shareholder’s relationship with the company. A drop from 85% to 80% moves numbers without moving control, and the IRS is unlikely to call that meaningful. Experienced planners avoid leaning on this test because the answer depends on facts and circumstances that are hard to predict before an audit.
Partial Liquidation
The fourth test, Section 302(b)(4), is only available to noncorporate shareholders. It is evaluated at the corporate level rather than by looking at any one shareholder’s percentage change. The distribution qualifies when it is not essentially equivalent to a dividend measured by what the corporation did.
The typical fact pattern is termination of a qualified trade or business. If the corporation ran two separate business lines for at least five years, shuts one down, and distributes the proceeds while keeping the other going, the distribution qualifies. It can even be pro rata among all shareholders, something that would sink any of the shareholder-level tests. Partnerships, estates, and trusts look through to their individual partners or beneficiaries for the noncorporate requirement.
S Corporation Redemptions Follow a Different Path
A failed Section 302 redemption plays out differently for an S corporation. S corporations rarely carry accumulated earnings and profits unless they converted from C status or acquired a C corporation. Without E&P, the distribution moves through the ordering rules of Section 1368 instead of being immediately taxed as a dividend.
Under those rules the distribution first reduces the accumulated adjustments account (AAA) tax-free. Next, any accumulated E&P from a prior C period comes out as a taxable dividend. After E&P is exhausted, the distribution reduces stock basis tax-free. Only amounts above all those layers get taxed as capital gain. For an S corporation that has always been an S corporation and carries no E&P, failing Section 302 often produces no immediate dividend income at all, just a reduction in AAA and basis, with any excess taxed as capital gain. The practical stakes of failing the four tests are much lower for a pure S corporation than for a C corporation.
You May Not Be Able to Deduct a Loss
If the redemption price is below your basis, you might expect a capital loss. Section 267 blocks it when the transaction is between related parties, and in a closely held corporation you are very likely related to the corporation for tax purposes.10Office of the Law Revision Counsel. 26 USC 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Persons If you own more than 50% of the outstanding stock, counting direct and indirect ownership, the loss is disallowed entirely. The only statutory exception is a distribution in complete liquidation of the corporation.
Indirect ownership under Section 267 uses rules similar to Section 318, so even a minority shareholder can cross 50% through family members and entities. A shareholder who owns 30% directly while a spouse and children hold another 25% is over the line and gets no deductible loss. Calculate indirect ownership before assuming a loss exists.
The Installment Sale Trap
Closely held corporations frequently lack the cash to fund a full redemption at closing, so payments get spread over several years using a note. A redemption that qualifies as a sale under Section 302 can use installment reporting under Section 453, spreading the gain over the payment period and deferring tax until the cash arrives.
The note must carry adequate stated interest at or above the applicable federal rate (AFR) the IRS publishes monthly. For reference, the long-term AFR for December 2025 was 4.55% annually.11Internal Revenue Service. Revenue Ruling 2025-2412Office of the Law Revision Counsel. 26 U.S. Code 483 – Interest on Certain Deferred Payments13Office of the Law Revision Counsel. 26 U.S. Code 1274 – Determination of Issue Price
Here is the trap. If the redemption fails Section 302, the entire distribution is treated as a dividend in the year the obligation is created, not spread over the payments. Installment reporting is only available for sales. Getting the classification right before closing is not something you can fix afterward.
Documentation the IRS Will Expect
Closely held redemptions invite scrutiny because the buyer and seller are related. Documentation is the primary defense against recharacterization.
The redemption agreement should specify the number of shares redeemed, the purchase price, payment terms, and any closing conditions. The board should adopt a formal resolution authorizing the redemption and confirming the corporation has the financial capacity to complete it under state law. Most states require the payment to come from legally available funds and prohibit redemptions that would render the corporation insolvent.
An independent valuation is essential because there is no public market price for a closely held company. The valuation should be performed by a qualified professional and documented in a written report explaining the methodology. An inflated price looks like a disguised dividend; a deflated price looks like a gift. Professional valuations for closely held corporations range from a few thousand dollars for simple businesses to $30,000 or more for complex entities.
For a complete termination that relies on a family attribution waiver, the shareholder must attach the waiver statement to a timely filed return for the year of the redemption, confirming no prohibited interest remains and agreeing to the ten-year notification requirement.6Office of the Law Revision Counsel. 26 U.S. Code 302 – Distributions in Redemption of Stock Miss that filing and there is no way to claim the waiver later.
