Do I Need a Foreign Subsidiary, or Can I Just Run a Branch Abroad?

Your startup has started winning customers overseas.

The first international contracts are signed, and you’re preparing to hire someone in another country to support your growing customer base.

Now you face an important decision.

Should you establish a local company, or can you simply operate as an extension of your US business?

At first glance, running a branch appears to be the quicker and less expensive option.

However, this decision affects much more than incorporation costs. It can determine who is responsible for local liabilities, how your profits are taxed, how employees are hired, and whether your US parent company becomes directly exposed to legal and financial risks overseas. Choosing the right structure early can make international expansion much easier as your business grows.

What Is a Foreign Branch?

A foreign branch is not a separate legal business. Instead, it operates as an extension of your existing US company.

Because the branch and the parent company are legally connected:

• The parent company generally remains responsible for the branch’s obligations.
• Local legal claims may reach the US parent.
• The branch’s activities may bring the parent company within the scope of local tax and regulatory rules.

Although branches are often faster to establish, founders should understand that simplicity also comes with additional exposure.

A Subsidiary Creates a Separate Legal Entity

A foreign subsidiary works differently. It is a separate company formed under the laws of the country where it operates, even if the US parent owns all of its shares.

This structure generally provides several advantages. A subsidiary can:

• Limit the parent company’s exposure to local liabilities.
• Pay taxes under local rules.
• Enter contracts in its own name.
• Raise capital locally where appropriate.

Many companies choose this structure because it separates the parent company from the day-to-day legal obligations of the foreign business.

Cost and Protection Usually Move in Opposite Directions

The choice between a branch and a subsidiary often comes down to balancing cost against protection.

Branches usually cost less to establish, require less initial administration, and allow faster market entry.

Subsidiaries generally require local incorporation, involve ongoing compliance, cost more to maintain, and provide stronger legal separation between the foreign operation and the US parent.

For founders, the question is not simply which option is cheaper today, but which structure best supports the company’s long-term plans.

You May Not Need Either Option Immediately

Many startups assume they must immediately create a branch or subsidiary before hiring internationally. That is not always necessary.

Many early-stage companies initially use an Employer of Record (EOR) when hiring one or two employees in another country.

An Employer of Record hires the worker through its local legal entity while handling payroll and employment compliance.

This allows founders to test a new market before deciding whether establishing their own local entity makes business sense.

Tax and Employment Rules Still Matter

Expanding internationally introduces more than corporate structure decisions.

Local laws may create obligations involving:

• Permanent establishment tax exposure.
• Payroll registration.
• Mandatory employee benefits.
• Local employment protections.
• Termination requirements.

These requirements vary significantly between countries.

Ignoring them simply because the parent company is based in the United States can create unexpected compliance issues after operations begin.

Think About Your Long-Term Expansion Plans

The right structure depends largely on how your business intends to grow.

A short-term market test with one employee may justify a different approach than opening a permanent office with a growing local workforce.

Before making a decision, founders should consider:

• How many employees they expect to hire.
• Whether the operation is temporary or permanent.
• The potential legal exposure of the parent company.
• The ongoing compliance costs associated with each option.
• The tax implications in both countries.

Looking beyond the initial setup cost often leads to a more sustainable international expansion strategy.

Common Founder Mistakes

• Choosing a branch simply because it costs less: Lower setup costs may come with greater legal and tax exposure because the parent company generally remains responsible for the branch’s obligations.
• Creating a subsidiary before the business has a meaningful local presence: Incorporating a separate company for a very small operation may create unnecessary compliance costs and administrative work.
• Ignoring local tax and employment laws: Permanent establishment rules, payroll obligations, employee benefits, and termination protections often apply regardless of where the parent company is incorporated.
• Overlooking Employer of Record solutions for early hiring: An Employer of Record may provide a practical way to hire internationally before deciding whether a permanent legal entity is necessary.

10-Minute International Expansion Self Check

• Will my foreign activities expose the US parent company to local liability?
• Is this market entry temporary or part of a long-term expansion strategy?
• Have I evaluated whether a branch could create permanent establishment tax exposure?
• Do I understand the ongoing compliance costs of maintaining a subsidiary?
• Would an Employer of Record meet my current hiring needs?
• Have I reviewed local employment and payroll requirements?
• Do I understand how profits may be taxed in both countries?

If you cannot answer yes to most of these, you are not ready to choose a structure yet.

Bottom Line

There is no single structure that works for every startup expanding internationally. A branch may provide a faster and less expensive way to enter a new market, while a subsidiary offers greater legal separation and liability protection. For businesses still testing demand, an Employer of Record may provide another practical option. The best choice depends on your hiring plans, risk tolerance, tax considerations, and long-term international growth strategy.
