Can a Corporation Own Another Corporation?

Yes, a Corporation Can Own Stock in Another Corporation

State corporate statutes generally don't restrict who can hold a corporation's shares. A corporation can purchase, be issued, or otherwise acquire stock in another corporation, just as an individual, a trust, or an LLC can. This is how parent-subsidiary structures, holding companies, and corporate groups are built: one corporation (the parent) owns stock in one or more other corporations (subsidiaries), which may themselves own stock in further corporations.

Wholly Owned Subsidiaries and Partial Ownership

When a parent corporation owns 100% of a subsidiary's stock, that subsidiary is a wholly owned subsidiary; the parent elects its entire board and controls every shareholder decision. A corporation can also own less than 100%, anywhere from a small minority stake up to a controlling majority, without the owned corporation becoming a subsidiary in the full sense. There's no separate state filing that creates a parent-subsidiary relationship; it exists simply because of who owns the shares, as reflected in the subsidiary's own stock ledger and stock certificates.

Why Businesses Use Parent-Subsidiary Structures

Companies commonly use a holding company structure to separate different lines of business, isolate liability so that a lawsuit against one subsidiary doesn't automatically expose the parent's other assets, or organize a business before a planned sale or investment in one division. Each corporation in the group keeps its own board, officers, bylaws, and stock, and each is formed and maintained under its own state's corporate law, even when the same parent owns all of them.

The IRS Affiliated Group Test

For federal tax purposes, commonly owned corporations can be treated as an affiliated group, which matters because an affiliated group can elect to file one consolidated federal income tax return instead of separate returns for every corporation. Under 26 U.S.C. Section 1504, a group qualifies when a common parent corporation owns stock representing at least 80% of the total voting power and at least 80% of the total value of at least one other includible corporation, and that 80% test is met, directly or through other group members, for every other corporation in the chain. Falling just short of 80% on either the vote or the value test keeps a corporation out of the affiliated group, even if the parent otherwise controls it.

Consolidated Returns Are an Election, Not Automatic

Qualifying as an affiliated group doesn't by itself change anything; the group has to affirmatively elect to file a consolidated return, and once made, that election generally applies to future years as well. Filing consolidated lets the group offset one subsidiary's loss against another's profit in the same year, among other effects, but it also means every member is generally liable for the group's full consolidated tax liability. Groups that don't elect consolidation simply file separate corporate returns for each corporation, even though they're commonly owned.

Each Corporation Still Pays Its Own State Fees

Owning a subsidiary doesn't merge the group's state-level obligations into one filing. Each corporation in the group, parent and every subsidiary, still owes its own state's Articles of Incorporation fee when it's formed, its own annual report or franchise tax every year after, and its own registered agent in its state of incorporation. A holding company structure can mean paying several states' formation and annual fees at once, one set per entity.

Keep Each Corporation's Formalities Separate

Owning stock in a subsidiary doesn't erase the fact that it's a separate legal entity. Each corporation in a group still needs its own board actions, its own bylaws, and its own stock records, and a parent that treats a subsidiary's assets and finances as interchangeable with its own risks a court disregarding the separation between them if the subsidiary is ever sued. See our guide on protecting the corporate veil for the habits that keep each entity's liability shield intact.

A Corporation Owning Another Doesn't Automatically Shield the Parent

Liability protection between a parent and subsidiary depends on actually running them as separate entities, with their own bank accounts, boards, and records. A parent that mixes funds, ignores the subsidiary's own governance, or treats the subsidiary as a mere department rather than a distinct corporation can lose the liability separation a court would otherwise respect.

State Foreign Qualification Still Applies to Each Entity

If a subsidiary does business in a state other than where it's incorporated, it has to register there as a foreign corporation in its own right, separately from whatever states its parent is registered in. Owning a subsidiary doesn't consolidate each entity's state-level compliance obligations into one filing.

Minority Ownership Has Its Own Rules

A corporation that owns less than a controlling stake in another corporation is a minority shareholder, with rights set by the other corporation's bylaws and the state's corporate law, not by whatever agreement the two corporations' officers might informally reach. Significant minority investments are usually documented with a shareholders' agreement or stock purchase agreement spelling out voting, transfer, and information rights.

This Is Not Legal or Tax Advice

Setting up or restructuring a parent-subsidiary group involves state corporate law questions about liability separation and federal tax questions about consolidated returns and intercompany transactions.
