What Are Subsidiaries? Understanding Their Role in Business
Table of Contents
When you hear about big companies like Google, Disney, or Amazon, you might imagine one giant business doing everything. But behind the scenes, many large corporations are actually made up of smaller companies called subsidiaries.
A subsidiary is a business that is owned or controlled by a bigger company, often called the parent company. Subsidiaries can have their own name, their own products, and even their own management team. But the parent company still makes the key decisions.
In this guide, you’ll learn what subsidiaries are, how they work, why companies use them, and the advantages and risks of having them. We’ll also include clear examples and FAQs to make the topic simple to understand.
What Is a Subsidiary?
A subsidiary is a company that is owned or controlled by another business called the parent company. According to the FPPC, the official subsidiary definition in corporate law, means the parent owns more than 50% of the subsidiary’s voting shares, giving it the power to make major decisions.
A simple way to define subsidiary is:
A smaller company that is controlled by a larger company.
Even though a subsidiary may run its own daily operations, it is still connected to the parent company legally and financially. In business terms, the subsidiaries definition means each subsidiary is a separate legal entity, but the parent company holds the ultimate authority.
It also helps to understand where a holding company fits in. A holding company definition refers to a business that doesn’t sell products or services of its own—it mainly exists to own shares in other companies, including multiple subsidiaries. Holding companies allow large organizations to manage several businesses under one structured umbrella.
Examples of well-known subsidiaries:
- Instagram → subsidiary of Meta
- YouTube → wholly owned subsidiary of Alphabet
- Whole Foods → subsidiary of Amazon
- Pixar → subsidiary of Disney
Subsidiaries show up on a company’s balance sheet as an investment. This accounting structure keeps the companies legally separate while still connected.

Types of Subsidiaries
Not all subsidiaries are structured the same way. Ownership levels change how much control the parent company has. Here is a simple breakdown of the two main types:
| Type of Subsidiary | Ownership Level | Parent Company Control | How It Works | Common Uses |
| Wholly Owned Subsidiary | Parent owns 100% of the company (e.g. YouTube → Alphabet) | Parent has full control over strategy, operations, and finances | Subsidiary operates under its own name but follows the parent’s goals and policies | Brand expansion, risk protection, entering new markets, keeping separate brand identity |
| Minority-Owned Subsidiary | Parent owns 51–99% of the company (e.g. Disney+ Hotstar → Disney) | Parent controls major decisions but shares ownership | Subsidiary has more independence but stays aligned with parent strategy | Joint ventures, international expansions, meeting regulatory ownership rules, sharing financial risk |
Parent–Subsidiary Relationship
This relationship determines how much influence the parent has. When people ask “what is a parent company,” they’re asking about the controlling business entity.
The parent company may:
- Appoint the subsidiary’s board of directors
- Approve major financial decisions
- Require consolidated financial reporting
- Set strategic direction and goals
But subsidiaries often still:
- Operate their own teams
- Maintain their own branding
- Make day-to-day business decisions
- Manage local operations
This balance helps companies grow without becoming too centralized or slow. An organizational chart typically shows the parent at the top with subsidiaries branching below, making the structure easy to visualize.
How Subsidiaries Operate
Even though subsidiaries belong to a parent company, they operate as separate legal businesses with their own responsibilities.
Legal and Ownership Structure
Subsidiaries are separate legal companies, even though they’re owned or controlled by a parent business. This means each subsidiary has its own:
- EIN (Employer Identification Number)
- Tax responsibilities
- Contracts and agreements
- Legal protections
- Liabilities
Because the subsidiary is legally separate, the parent company is usually protected from lawsuits, debts, or financial problems that belong to the subsidiary.
Under California’s legal guidelines, a business must meet certain ownership and control thresholds to be considered a true subsidiary. These rules help define when a parent company has enough influence to be legally responsible for consolidated reporting.
Subsidiaries can be set up in different legal forms, including:
- Corporations
- LLCs
- Partnerships (less common)

Management and Operations
Subsidiaries usually have their own CEO or management team. They make day-to-day decisions, but the parent sets high-level goals, budgets, and strategy. This subsidiary company meaning in practice means operational independence within strategic boundaries.
Operational considerations include:
- Hiring and personnel management
- Daily production or service delivery
- Customer relationship management
- Local market strategies
An organizational chart usually shows the parent at the top with subsidiaries branching below—similar to a family tree of companies.
Accounting and Balance Sheets
In accounting, parents and subsidiaries are connected through consolidated financial statements. That means the parent company combines the subsidiary’s data with its own for reporting.
Subsidiaries appear as “investments” or “controlled companies” on statements. The subsidiary pronunciation may vary (sub-SID-ee-air-ee), but the accounting treatment follows clear standards. Learn more about tracking these financial relationships with assets and liabilities guides.
Companies use various tools to manage subsidiary finances, including:
- Profit and loss statements for each entity
- Cash flow formulas to track movement
- Retained earnings calculations for growth planning
- Annual reports combining all entities
Advantages and Disadvantages
Subsidiaries offer many benefits for growing companies, but they also come with challenges that businesses must manage carefully.
| Advantages | Disadvantages |
| Risk Protection — If a subsidiary faces legal trouble or debt, the parent company is often shielded. | Complex Management — Coordinating multiple companies requires strong oversight, communication, and alignment. |
| Brand Flexibility — Each subsidiary can focus on a different brand or audience without confusing customers. | Higher Administrative Costs — More entities mean more accounting, legal requirements, and tax filings. |
| Faster Expansion — Companies can acquire existing businesses or enter new markets quickly through subsidiaries. | Communication Gaps — Subsidiaries may drift from the parent company’s goals if not managed closely. |
| Tax Benefits — Some countries provide tax advantages for subsidiaries, especially with smart planning like pro-rata allocations or perpetuity strategies. | Increased Regulatory Scrutiny — Large organizations with many subsidiaries face more compliance and regulatory review. |
| Focused Management — Each subsidiary can specialize in its own operations without being slowed down by the parent company. | Potential Operational Overlap — Without clear boundaries, subsidiaries may duplicate roles or compete for resources. |
Managing Subsidiary Finances
Proper financial management becomes more complex with subsidiaries. Many growing businesses use automated invoicing to streamline billing across multiple entities.
Smart financial practices include:
- Tracking each subsidiary’s performance separately
- Using business reports for consolidated insights
- Implementing payment notifications for timely collections
- Setting up online payments for efficient transactions
Maintaining clear financial records helps companies get paid faster while keeping parent and subsidiary finances properly separated. Tools like an ROI calculator can help assess whether creating subsidiaries makes financial sense for your growth strategy.
