IRC Section 302 Stock Redemption & Section 318 Attribution Evaluator

Analyze tax characterization (Capital Gain vs. Dividend) under IRC Section 302 with graph-based Section 318 constructive attribution modeling.

Determining if a stock buyback qualifies for Exchange Treatment (Capital Gain) under Section 302(b) or is treated as a Dividend is highly complex. Stock owned by related family members, trusts, partnerships, and controlled corporations must be constructively attributed using the intricate and counter-intuitive rules of Section 318, including strict limits on reattribution (e.g. no sidewise attribution). Use our presets below or construct a custom corporate cap table to find out.

* Note: Going from a sole majority control position (>50%) to a minority position (<50%) is almost universally treated as a meaningful reduction by the IRS and courts.

Navigating the Complexities of IRC Section 302 Stock Redemptions

In corporate tax planning, a stock redemption—where a corporation repurchases its own shares from an existing shareholder—poses a critical classification question: Is the transaction treated as a Sale or Exchange of stock (typically yielding preferential capital gains taxation) or as a Section 301 Distribution(treated as a dividend to the extent of the corporation's earnings and profits)?

The Statutory Dilemma: Sale vs. Dividend

Historically, shareholders strongly prefer exchange treatment under IRC § 302(a). In an exchange, the shareholder is taxed only on the gain (the excess of the redemption proceeds over their adjusted tax basis in the redeemed shares). This results in basis recovery and preferential capital gains tax rates. Conversely, if a redemption is characterized as a distribution, the gross proceedsare taxed as dividend income (under § 301) with zero offset for basis, unless the corporation has no remaining Earnings & Profits (E&P).

Deciphering the Section 318 Attribution Rules

To prevent taxpayers from circumventing dividend characterization by keeping shares in the names of family members, trusts, or controlled shell entities, the Internal Revenue Code mandates the application of the Section 318 constructive ownership rules. Under § 318, shares physically held by one taxpayer are constructively attributed to another.

  • Family Attribution (§ 318(a)(1)): Stock is attributed between spouses, and from parents, children, and grandchildren. Sibling-to-sibling attribution is notably absent.
  • Entity-to-Member (§ 318(a)(2)): Stock owned by a partnership, estate, or trust is attributed proportionately to its partners or beneficiaries. Stock owned by a corporation is attributed proportionately only to shareholders who own 50% or more in value of the company's stock.
  • Member-to-Entity (§ 318(a)(3)): Stock owned by partners, trust beneficiaries, or 50%+ corporate shareholders is attributed 100% to the partnership, trust, estate, or corporation.
  • Options (§ 318(a)(4)): A person holding an option to buy stock is treated as owning that stock.

The Substantially Disproportionate Safe Harbor (Section 302(b)(2))

To qualify for the safe harbor under § 302(b)(2), three statutory requirements must be satisfied immediately after the redemption:

  1. The shareholder must own (actually and constructively) less than 50% of the total combined voting power of all classes of stock entitled to vote.
  2. The shareholder's post-redemption constructive voting stock percentage must be less than 80% of their pre-redemption constructive voting percentage.
  3. The shareholder's post-redemption constructive common stock percentage must be less than 80% of their pre-redemption constructive common percentage.

Complete Termination of Interest and the Section 302(c)(2) Family Waiver

Section 302(b)(3) grants exchange treatment if the shareholder completely terminates their actual proprietary interest in the corporation. In a close family-held business, complete termination is often thwarted because family attribution (§ 318(a)(1)) remains. However, Section 302(c)(2) allows the shareholder to wave family attribution by executing a triple-i agreement.

Under the triple-i agreement, the redeemed shareholder must completely sever ties, holding no interest in the corporation (as officer, director, or employee) other than as a creditor, and must agree not to acquire any such interest (except by bequest or inheritance) for 10 years following the distribution date.

Pitfalls to Avoid: Sidewise Attribution and Option Triggers

A common mistake in corporate restructurings is misunderstanding reattribution rules. Under § 318(a)(5)(C), stock constructively owned by an entity via member-to-entity attribution cannot be reattributed from the entity to another member (the no sidewise attribution rule). However, stock attributed via entity-to-member rules can be reattributed via family rules. This tool accurately models these path dependencies, allowing tax practitioners to confidently simulate redemptions without triggering unexpected tax audits.

Accounting & Compliance Best Practices

When executing redemptions, corporate accountants must prepare simultaneous balance sheet adjustments. The redemption amount up to the par value of redeemed shares is debited to common stock, with the remainder allocated between Paid-in Capital and Retained Earnings (pursuant to § 312). Detailed records of the triple-i agreement and the shareholder's annual tax filing disclosure statements must be maintained for a minimum of ten years to withstand IRS audit scrutiny.
