Leading international companies have created a collective of 370,000 subsidiaries, many of which operate in the U.S. Before you follow in their footsteps, you must understand not only what a subsidiary company is but also how to manage one effectively.
A subsidiary company is owned or controlled by a parent or holding company. Usually, the parent company will own more than 50% of the subsidiary company. This gives the parent organization the controlling share of the subsidiary. Sometimes, control is achieved simply by being the majority shareholder. When a parent organization owns all common stock of a company, it is known as a ‘wholly owned' subsidiary.
This guide will explain:
Subsidiary definition: a company that is at least 50% owned by a parent or holding company.
A subsidiary company is either partially or wholly owned by another company. That company can be either a parent company, which is its own functioning company, or a holding company, which solely controls other companies and investments.
To be a subsidiary, a company has to be at least 50% owned by the parent or holding company. Subsidiaries 100% owned are considered wholly owned subsidiaries.
Subsidiaries are crucial in how multinational corporations structure their operations, manage risk and expand into new markets. While owned or controlled by a parent company, subsidiaries maintain some independence. Understanding the core characteristics of a subsidiary helps clarify precisely what a subsidiary is, how it functions and why it’s strategically crucial for businesses.
Distinguishing between a subsidiary and other business relationships is key to navigating corporate structures. Below are comparisons between subsidiaries and commonly confused entities:
A parent company controls a subsidiary, while a sister company is another entity owned by the same parent. The key distinction is that sister companies are peers — not in a controlling relationship with each other — though they may collaborate or share resources.
An affiliate is a company where another firm holds a minority interest, typically less than 50%. In contrast, a subsidiary involves majority or full ownership, giving the parent company significant or total control over decisions and operations.
A division is an internal segment of a company, not a separate legal entity. It operates under the parent company’s name and legal identity. On the other hand, a subsidiary is a standalone legal entity, even if wholly owned, and often has its own branding, financials and liability.
A subsidiary and a parent company are legally separate entities. This means that individual organizations pay taxes and debt, limiting shared liabilities between the companies. Subsidiary companies will have independence from the parent company and, in many cases, are individual brands. However, the parent company will naturally influence the subsidiary’s operations, including governance. The parent company can elect the board of directors as the major shareholder and drive the overall business strategy.
Subsidiaries are a commonly used structure for both national and international corporations. Tiers of subsidiaries group a range of industries within a multinational conglomerate. The structure can also bring together companies from within one sector in a corporate group.
A parent company controls its subsidiary by owning all or most of its stock. If that’s the case, the parent company can control most subsidiary operations, including assigning the board members.
The parent company can also include clauses in the subsidiary’s Articles of Incorporation to assign certain powers, such as requiring the parent company’s approval to pass bylaw changes or take certain actions.
That said, parent companies reap the benefits of subsidiaries when the subsidiary can operate more independently. This allows the subsidiary to set its own corporate strategy and objectives, which often significantly differ from those of the parent company.
Typically, a subsidiary cannot be liable for a parent company. Because they’re legally separate entities, they retain their own liability, meaning the parent company usually isn’t liable for the subsidiary’s actions either.
A subsidiary can leave a parent company, but the structure of the subsidiary/parent company relationship makes this uncommon. To leave the parent company, the subsidiary’s shareholders and board of directors would have to approve it. However, the parent company is among the shareholders — and, sometimes, the only shareholder — so it’s unlikely that a vote to leave the parent company would pass.
A subsidiary can sue a parent company, but it’s exceedingly rare and depends on the subsidiary’s Articles of Incorporation. To sue, the subsidiary has to prove damages due to the parent company — a difficult thing to do because the parent company owns the subsidiary. However, it’s still possible to sue if the parent company’s actions directly interfered with the subsidiary’s contractual obligations and the subsidiary suffered damages as a result.
Subsidiary companies will be owned by either a parent company or a holding corporation. A wholly-owned subsidiary company will be entirely owned by the parent or holding corporation. In other cases, parent companies will have the controlling share of a subsidiary company. In practice, this means owning more than half of a company’s common stock. So, by definition, parent companies have majority ownership or control of a subsidiary.
As the major shareholder, parent companies will have the deciding vote when electing the directors in the boardroom. In many cases, a member sits on the board of both the parent and subsidiary companies. Because of this, parent companies will significantly influence the strategic direction of subsidiaries, including any steering committee groups.
There are two types of subsidiary companies: wholly owned and partially owned. The primary difference lies in the parent or holding company's ownership stake.
Wholly-owned subsidiary: A wholly-owned subsidiary is 100% owned by the parent corporation. The parent company holds all common stock, which means they have sole influence over the subsidiary’s operations. This is generally achieved through a parent company acquiring full control of a company or by founding the subsidiary company itself. The wholly-owned subsidiary company is still legally recognized as its own entity.
Normal/partially-owned subsidiary: A normal subsidiary is when a parent or holding corporation owns more than half of the common stock. This means the subsidiary will have multiple shareholders who can influence the corporation’s ongoing operations.
The main benefit of subsidiary companies is that they are different legal entities from their parent company. This means the two companies can limit shared liabilities or obligations and will be separate in terms of regulation or tax. This legally recognized separation is a key difference between a branch and a subsidiary company.
Some other common reasons parent companies also use subsidiaries for the following purposes:
A subsidiary company may sound like a win-win. While it’s true that they shelter the parent from liabilities, offer tax benefits and facilitate growth, they also greatly complicate the corporate structure. Corporations considering a subsidiary should consider both the pros and cons of a subsidiary structure before moving forward.
Many modern businesses have subsidiaries; some offer liability protection, while others allow the parent company to reach new industries or territories. For example, PepsiCo isn’t just a company; it’s a conglomerate that owns more than one subsidiary company, including Mountain Dew, Frito-Lay and even Quaker Foods.
More common examples of subsidiary companies include:
The Securities and Exchange Commission (SEC) requires publicly listed companies to disclose their subsidiaries, including when they acquire or dispose of a subsidiary. As a result, this information is publicly available, and you can find the subsidiaries of a company if you know where to look.
A company’s subsidiaries are usually listed on:
A parent company can either create a subsidiary company or purchase the majority shares in an existing company. If founding a new subsidiary, parent companies will need to:
Establishing a subsidiary involves setting up a new business entity, but it also brings a host of regulatory and accounting responsibilities. Companies must navigate financial reporting standards, jurisdiction-specific compliance rules and tax and audit requirements that vary by region. Understanding these implications helps ensure that legal or operational risks do not outweigh the benefits of a subsidiary structure.
1. Consolidated financial reporting: Parent companies are typically required to consolidate the financial results of their subsidiaries into a single set of financial statements. This ensures stakeholders have a full view of the company’s financial position and performance, but it also adds complexity to accounting and reporting processes.
2. Compliance requirements: Subsidiaries must adhere to local and international regulations, depending on their location and industry. The layered compliance landscape they face requires strong governance and legal oversight. For example:
3. Impacts on audits and tax filings: Each subsidiary may be subject to its own audit requirements and tax obligations based on jurisdictional rules. While some audits are conducted independently at the subsidiary level, others are rolled up into the parent company’s global audit. Tax implications can be especially complex when dealing with transfer pricing, foreign income taxes or intercompany transactions.

A subsidiary company can be either an LLC or a corporation. The parent company will decide which structure the subsidiary will take. This is usually a financial and legal decision. While both LLCs and corporations limit liability, they are taxed differently.
Subsidiaries can be both wholly-owned (100% owned) or not-wholly-owned. A parent company only needs to own more than 50% of another company’s stock for that company to be considered a subsidiary.
Yes. Subsidiaries typically operate on their own and follow their own structure, but they benefit from the resources and connection to their parent company.
There can be multiple layers or tiers of subsidiary companies within a wider corporate group. A company owned by a parent corporation is a first-tier subsidiary. But this subsidiary company may hold majority shares of a subsidiary company of its own. The second subsidiary company can be described as a second-tier subsidiary of the overall parent corporation. The tiers can continue depending on the complexity of the corporate group.
The parent company will have a degree of control over both tiers of subsidiary companies. As the major shareholder, it will hold direct control of a first-tier subsidiary. It can elect the board of directors and influence strategic business decisions when required. Using this influence, the parent company can exercise indirect control of the second-tier subsidiary.
If the entire subsidiary company is owned by the parent corporation, this is known as a wholly owned subsidiary. A wholly-owned subsidiary company has no other shareholders. This gives the parent corporation a major influence on the company’s ongoing operations. Direct control of who sits on the board of directors helps define the aims and strategic decisions made by the subsidiary company.
When a corporation owns a minor share of another business, the company is known as an associate or affiliated company. In this case, a corporation owns a portion of a company but not enough to have full ownership. Usually, this is when a parent corporation owns less than half of a company's common shares. To be considered a subsidiary, the parent corporation would need to own the majority of the company.
With a minority share of common stock, a parent corporation will have no direct control over strategic decisions. In most cases, a larger company will invest in a smaller associate company. The parent company will usually record the value of this investment on its financial statements.
Sister companies are subsidiary companies that share a parent or holding company. Most sister companies operate independently and have no relationship other than the owning corporation.
Subsidiaries do have their own CEO, management team and board of directors. However, the parent company does have sway over who holds those positions.
In most cases, no subsidiary can own shares in its parent company. This is known as a circular ownership structure, and it's typically prohibited by corporate law in many jurisdictions. The logic is that control must flow in one direction: from parent to subsidiary. If a subsidiary were to own shares in its parent, it could distort voting rights and financial reporting. In rare cases — such as cross-holdings in joint ventures — exceptions may apply, but these are strictly regulated.
Generally, a subsidiary is not liable for the debts of its parent company. One of the key legal benefits of forming a subsidiary is liability protection. Because a subsidiary is a separate legal entity, creditors of the parent company cannot pursue the subsidiary’s assets — unless there is fraud, co-mingling of assets or a legal basis to "pierce the corporate veil." However, shared branding or intercompany guarantees can blur these lines, so legal structuring matters.
Subsidiaries are taxed separately from their parent companies and must comply with the tax laws of the country or state in which they are incorporated. This means they file their own tax returns and may be subject to different corporate tax rates, withholding taxes, and transfer pricing rules. For multinational companies, this creates both tax planning opportunities and compliance challenges, especially around intercompany transactions and profit shifting.
Key considerations include:
Closing a subsidiary involves a formal legal process, which can vary by jurisdiction. The typical steps include:
Keep in mind that closing a subsidiary may trigger final tax filings, employee notifications and regulatory reporting. It’s wise to consult legal and tax advisors to ensure a clean exit.
