A corporate spin-off is a transaction in which a parent company distributes shares of a subsidiary to its existing shareholders, creating a separate, publicly traded company. If you own stock in the parent on the right date, shares of the new company show up in your brokerage account automatically, in proportion to what you already hold. You pay nothing, and you do not give up your parent company shares. When it is over, you own two stocks instead of one.
The point of the transaction is usually to let each business operate on its own, with its own management, strategy, and investor base.
Spin-Off vs. Split-Off vs. Carve-Out
These three terms get used loosely, but they describe different transactions with different consequences for you.
In a spin-off, every shareholder automatically receives shares in the new company based on how many parent shares they already own. No action is required, and no shares change hands.
A split-off is a choice. The parent offers shareholders the option to exchange some of their parent shares for shares in the new entity. Participation is voluntary, and shareholders who opt in give up a portion of their parent stock in return.
A carve-out is different again. The parent sells a portion of the subsidiary to the public through an IPO, keeping a majority stake and pocketing the cash. Outside investors come in, and existing shareholders do not automatically receive anything.
How Shares Reach Your Account
Spin-off shares are distributed pro-rata based on a ratio the board sets. If you own 100 shares of the parent and the ratio is one new share for every five parent shares, 20 shares of the spin-off will appear in your account. You do not need to take any action, pay anything, or surrender your parent shares to participate.1FINRA. What Are Corporate Spinoffs and How Do They Impact Investors?
The Dates That Decide Whether You Get Shares
Three dates control who receives the distribution:
- Record date. You must be a shareholder of record by this date to receive the distribution. The parent’s board sets it when authorizing the spin-off.
- Ex-distribution date. Typically set on or one business day before the record date. If you buy parent shares on or after this date, you will not receive the spin-off shares; the seller keeps them.2Investor.gov U.S. Securities and Exchange Commission. Ex-Dividend Dates: When Are You Entitled to Stock and Cash Dividends
- Distribution date. The date the new company’s shares actually land in your account.
Fractional Shares
When the ratio does not divide cleanly, most companies pay cash instead of issuing a partial share. If you were entitled to 20.4 shares, you would get 20 shares and a small cash payment for the 0.4. Under federal tax regulations, that cash-in-lieu payment is not treated as a taxable dividend as long as the company’s purpose is simply to avoid the administrative burden of issuing fractional shares rather than to shift ownership percentages among shareholders.3eCFR. 26 CFR 13.10 – Distribution of Money in Lieu of Fractional Shares
Splitting Your Cost Basis Between the Two Stocks
Once the spin-off shares arrive, the cost basis of your original parent shares has to be divided between the parent stock you still hold and the new stock you just received. Under Section 358 of the Internal Revenue Code, the basis is allocated across all the shares you hold after the distribution.4Office of the Law Revision Counsel. 26 U.S. Code 358 – Basis to Distributees
In practice, the allocation is based on the relative fair market values of the parent and spin-off shares on the distribution date. Say your original parent shares had a cost basis of $10,000. If, on the distribution date, the parent stock represents 75% of the combined value and the spin-off stock represents 25%, you would allocate $7,500 of basis to the parent shares and $2,500 to the spin-off shares. Most companies publish the allocation percentages shortly after the spin-off so shareholders can report the numbers correctly. Getting this right matters. An incorrect allocation can cause you to overstate or understate your gain when you eventually sell either stock.
Is a Spin-Off Taxable?
A properly structured spin-off is tax-free at the time of the distribution, for both the corporation and its shareholders. To get that treatment, the transaction has to satisfy the requirements of Internal Revenue Code Section 355. Companies typically seek an IRS private letter ruling or a legal opinion before proceeding, because failing any single test can trigger immediate tax.
The Core Section 355 Requirements
Control. The parent must control the subsidiary immediately before the distribution. Under Section 368(c), that means owning at least 80% of the total combined voting power of all voting stock and at least 80% of the shares of every other class of stock.5Office of the Law Revision Counsel. 26 U.S. Code 368 – Definitions Relating to Corporate Reorganizations
Active trade or business. Both the parent and the spin-off must be engaged in an active trade or business that has been conducted for at least five years before the distribution. This blocks a company from buying a small business shortly before a spin-off just to check the box.6Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation
Not a device. The transaction cannot be used primarily as a device to distribute earnings and profits at favorable tax rates. The IRS weighs several factors, including the ratio of non-business assets like cash and investment securities to operating assets in each company after the split. A large mismatch between the two companies’ non-business asset percentages is treated as evidence of a device, and pre-arranged sales of the new shares by shareholders weigh heavily against the transaction.7Federal Register. Guidance Under Section 355 Concerning Device and Active Trade or Business
Corporate business purpose. The spin-off must serve a real non-tax purpose, such as improving access to capital, resolving regulatory conflicts, or letting each business pursue a focused strategy.6Office of the Law Revision Counsel. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation
The 50% Acquisition Trap
Section 355(e) is a separate anti-abuse rule. If one or more persons acquire 50% or more of either the parent or the spin-off as part of a plan connected to the distribution, the parent has to recognize gain on the distributed shares as if it had sold them. The law presumes such a plan exists if the acquisition happens within a four-year window running from two years before the distribution to two years after. The company can rebut that presumption by showing the spin-off and the acquisition were not coordinated.8Office of the Law Revision Counsel. 26 U.S. Code 355 – Distribution of Stock and Securities of a Controlled Corporation
If the Spin-Off Fails to Qualify
When a distribution does not meet Section 355, the shareholder-level tax hit is significant. The distributed shares are treated as a distribution under Section 301, meaning the value is taxed as a dividend to the extent of the parent’s earnings and profits, with any excess treated as a return of capital or capital gain.9GovInfo. 26 USC 355 – Distribution of Stock and Securities of a Controlled Corporation At the corporate level, the parent may owe tax on any built-in gain in the subsidiary’s shares as if it had sold them at fair market value.
What the New Company Looks Like on Day One
Before the distribution, the subsidiary has to be organized as a standalone corporation with its own articles of incorporation, registered agent, and governance framework. The parent transfers specific assets to it, including equipment, real estate, intellectual property, and contracts, along with the corresponding liabilities so the new entity is responsible for its own debts. The spin-off gets its own board of directors and executive team, its own credit rating, and its own capital structure. The parent and the spin-off sometimes keep limited commercial relationships in place, but the new company generally operates without the parent’s oversight or control over business decisions.
On the securities side, the parent files a Form 10 registration statement with the SEC on behalf of the new entity. Form 10 covers audited financial statements, business description, risk factors, executive compensation, and information about the new company’s directors and officers.10SEC.gov. Form 10 – General Form for Registration of Securities The SEC reviews the filing and can require amendments, a process that often takes months. Some spin-offs are exempt from Securities Act registration, but the parent still has to give shareholders and the market adequate information about the transaction.11Investor.gov U.S. Securities and Exchange Commission. Spin-Offs
The new company also has to apply to list its shares on an exchange. On Nasdaq, for example, the listing application must be submitted no later than 30 calendar days before the anticipated first trade date.12Nasdaq Listing Center. Applications, Notifications and Guides Whether shareholders have to vote on the spin-off depends on the exchange’s rules and state corporate law, but most spin-offs do not require a shareholder vote. Once Form 10 is effective and the exchange listing is approved, the new company begins trading under its own ticker.
