Complete vs. Incomplete Disposition: Stock and Passive Activity Rules

A complete disposition, in tax terms, is the full termination of your interest in an asset, activity, or entity, and it matters most in two places: a corporation’s redemption of all your stock under Section 302, and the sale of your entire interest in a passive activity under Section 469. Getting the disposition right converts an otherwise ordinary-income dividend into capital gain, or unlocks years of suspended passive losses that offset any kind of income. Getting it wrong leaves the money on the table. The rules that govern each context are separate, and each has traps that catch taxpayers who assume “I sold everything” is enough.

Complete Termination in a Stock Redemption

When a corporation buys back a shareholder’s stock, the default treatment under Section 302(d) is unfavorable. The redemption is treated as a property distribution under Section 301 and taxed as a dividend to the extent of the corporation’s earnings and profits.¹ That is ordinary income, and in 2026 the top federal rate reaches 37%.²

The way out is one of the exceptions in Section 302(b). The one that produces a true complete disposition is Section 302(b)(3), the “complete termination of a shareholder’s interest” test. Every share the shareholder owns must be redeemed, and after the redemption they must own nothing in the corporation.¹ When the test is satisfied, the redemption is a sale or exchange. Basis comes off the proceeds, and only the gain is taxed, at a long-term capital gains rate capped at 20%.

“Own nothing” is meant literally. Immediately after the redemption the former shareholder cannot serve as an officer, director, or employee. They can remain a creditor, but only if the debt is on standard commercial terms and is not subordinated to general creditors.¹

A 10-year look-forward period follows the redemption. During those years the former shareholder cannot acquire any interest in the corporation other than by inheritance. If they do, the IRS can recharacterize the original redemption as a dividend and assess the deficiency, with the limitations period running for one year after the shareholder reports the acquisition.¹

Why Family Businesses Usually Fail the Test

Section 318 treats stock held by related people and entities as owned by the taxpayer, even after every share in the taxpayer’s own name has been redeemed. Family attribution reaches a spouse, children, grandchildren, and parents. Siblings and in-laws are outside the rule. Entity attribution treats a taxpayer with an interest in a partnership, estate, trust, or corporation as owning a proportionate share of the stock that entity holds. Option attribution treats stock you have a right to acquire as already yours.³

In practice, a shareholder who has personally sold every share is still treated as owning stock the moment a spouse or child holds shares in the same corporation. The redemption fails the complete termination test and becomes a dividend.

Waiving Family Attribution

Section 302(c)(2) allows a shareholder to waive family attribution, but only on three conditions. Immediately after the redemption the shareholder can hold no interest in the corporation other than as a creditor. For the next 10 years the shareholder cannot acquire any interest except by inheritance. And the shareholder must file a written agreement with the IRS promising to report any prohibited acquisition and to keep the records needed to enforce that promise.¹

The waiver reaches family attribution only. Stock attributed through partnerships, trusts, or corporations still counts. An anti-abuse rule closes the obvious workaround: the waiver is unavailable if the shareholder received any of the redeemed stock from a related person within the prior 10 years, or transferred stock to such a person within that period without also having that stock redeemed in the same transaction.¹ Parking shares with relatives to manufacture a complete termination does not work.

Complete Disposition of a Passive Activity

Section 469 suspends losses from passive activities — rental properties and businesses in which you do not materially participate — so they cannot offset wages, salary, or investment income. The losses carry forward and can only offset passive income in later years.⁴

A complete disposition of the entire interest in a passive activity releases those suspended losses. They first offset any gain from the sale. If losses exceed the gain, they next offset income from other passive activities. Anything left over becomes deductible against income of any kind, with no limit.⁴ Years of frozen rental losses can turn into an immediate tax refund in the year of sale.

Two conditions have to be met. The disposition must cover the entire interest in the activity, and it must be fully taxable. Miss either one and the losses stay locked up.

Transactions That Look Like Dispositions but Aren’t

Several common structures fail one of those two conditions.

Sales to Related Parties

A sale of your entire interest to a related party does not release the losses. Section 469 cross-references Sections 267(b) and 707(b)(1) to define which relationships disqualify the transaction, and the list is broad: family members including siblings, spouses, ancestors, and lineal descendants; controlled corporations; grantors and their trusts; and partnerships and corporations under common ownership above 50%.⁵ Note the mismatch with Section 318’s family attribution: siblings are related for this purpose even though they are not attributed for the redemption test.

The suspended losses stay with the original taxpayer and remain available only against passive income. They release in the year the related party sells the interest to an unrelated buyer in a fully taxable transaction.⁴

Gifts

Gifting a passive activity is worse than selling to a relative. The suspended losses are permanently lost as deductions to the donor. They are added to the recipient’s basis, which will reduce any gain the recipient realizes on a future sale, but the original taxpayer never deducts them.⁴ Anyone thinking about giving a loss-generating rental to a family member should price that lost deduction into the decision.

Tax-Deferred Exchanges

Section 469(g)(1)(A) requires that all gain or loss be recognized on the disposition. A like-kind exchange under Section 1031, a contribution to a controlled corporation under Section 351, or a contribution to a partnership under Section 721 defers recognition by design, so none of them qualifies.⁴ Swap one rental for another in a 1031 exchange and the suspended losses attach to the replacement property and stay frozen until a later fully taxable sale.

Death and Installment Sales

Death is treated as a complete disposition, but with a cap. Suspended losses become deductible on the decedent’s final return only to the extent they exceed the step-up in basis the heir receives.⁴ If a rental has $100,000 in suspended losses and the step-up at death is $150,000, none of the losses are deductible; the step-up already gives a tax benefit that the code will not double. If instead the losses were $200,000, the excess $50,000 above the step-up is deductible on the final return.

An installment sale of the entire interest does qualify as a complete disposition, but the losses release proportionally with payments. Each year, the deductible portion of the suspended losses equals the ratio of gain recognized that year to total expected gain.⁴ Sell a rental with $60,000 of suspended losses for a total gain of $120,000, receive 25% of the gain in year one, and $15,000 of losses release against nonpassive income that year.⁶ The rest release as payments arrive.

What Is Actually at Stake

In a stock redemption, a valid complete termination means capital gains treatment: basis comes off the proceeds and the gain is taxed at up to 20%. A failed termination taxes the entire distribution as a dividend at ordinary rates reaching 37% in 2026, and the shareholder’s basis does not offset the distribution; it moves to remaining shares or is reallocated under Treasury regulations when attribution is the reason for failure.⁷

In a passive activity, a qualifying complete disposition turns years of trapped deductions into losses usable against any income in the year of sale. An incomplete disposition — a partial sale, a related-party sale, or a tax-deferred swap — keeps the losses suspended and waiting for passive income that may never arrive. A gift erases them as deductions entirely. The difference between an arm’s-length taxable sale and a transfer to a family member can easily run into five figures of forgone tax savings.
