Setting Up a U.S. Branch vs. Subsidiary: Tax and Legal Comparison for Turkish Companies

When a Turkish company decides to establish a U.S. presence, the foundational structural question is: branch or subsidiary?

A branch is not a separate legal entity — it is simply the Turkish parent company operating directly in the United States. A subsidiary is a separate U.S. legal entity (typically an LLC or C-corporation) owned by the Turkish parent.

The choice between these two structures affects:

• U.S. and Turkish tax obligations
• Liability exposure of the Turkish parent
• Regulatory and compliance requirements
• Operational flexibility
• Exit and restructuring options

There is no universally correct answer. The right structure depends on the nature of the U.S. business, the expected profitability timeline, the Turkish parent's tax position, and long-term strategic goals. This guide provides the framework for making an informed decision.

A branch office is the Turkish parent company doing business directly in the United States. Key characteristics:

• No separate legal entity: The branch is part of the Turkish parent, not a distinct company
• Direct liability: The Turkish parent is directly liable for all branch obligations — there is no liability shield between the branch's activities and the parent's assets
• Permanent establishment: A branch almost always constitutes a U.S. permanent establishment (PE) under the U.S.-Turkey Tax Treaty, subjecting the Turkish parent to U.S. income tax on branch profits
• Registration requirement: Foreign companies operating a branch in the U.S. must register as a "foreign corporation" (or foreign LLC) in each state where they do business — this is called "qualifying to do business" or obtaining a "certificate of authority"
• No separate capitalization: The branch uses the parent's capital; there is no minimum capital requirement

A U.S. subsidiary is a separate legal entity incorporated in the United States and owned (wholly or partially) by the Turkish parent. The most common forms are:

LLC (Limited Liability Company):

• Pass-through taxation by default (profits taxed at owner level, not entity level) — but a single-member LLC owned by a foreign corporation is treated as a disregarded entity for U.S. tax purposes, meaning the Turkish parent is taxed directly on LLC income
• Flexible governance structure
• No minimum capital requirement
• Preferred for real estate, joint ventures, and holding structures

C-Corporation:

• Separate taxable entity — pays U.S. corporate income tax at the entity level (currently 21%)
• Dividends paid to the Turkish parent are subject to U.S. withholding tax (15% under the U.S.-Turkey Tax Treaty)
• Preferred for operating businesses, U.S. venture capital investment, and companies planning a U.S. IPO
• Required for certain regulated industries and U.S. government contracting

S-Corporation: Not available to foreign shareholders — Turkish companies cannot own S-corporation stock.

Branch:

• The Turkish parent is subject to U.S. income tax on its effectively connected income (ECI) — income effectively connected with the conduct of a U.S. trade or business
• U.S. federal corporate income tax rate: 21%
• State income taxes apply in addition (rates vary by state; New York City imposes an additional city tax)
• The Turkish parent files a U.S. corporate income tax return (Form 1120-F) reporting branch income

Subsidiary (C-Corp):

• The U.S. subsidiary is a separate U.S. taxpayer subject to U.S. corporate income tax at 21% on its worldwide income
• State income taxes apply in addition
• The subsidiary files a U.S. corporate income tax return (Form 1120)

Key difference: Both structures are subject to U.S. corporate income tax at 21%. The tax rate on operating income is the same. The differences emerge in how profits are repatriated to Turkey and in the branch profits tax.

This is a critical difference. The United States imposes a branch profits tax on foreign corporations operating U.S. branches. The branch profits tax is a second layer of U.S. tax — in addition to the regular 21% corporate income tax — designed to approximate the withholding tax that would apply if the branch were a subsidiary paying dividends to its foreign parent.

• Statutory rate: 30%
• Treaty rate (U.S.-Turkey): 5% (significantly reduced under the Treaty)
• Tax base: The "dividend equivalent amount" — roughly, after-tax branch profits that are not reinvested in U.S. assets

Practical impact: A Turkish company operating a U.S. branch pays:

1. 21% U.S. corporate income tax on branch profits, plus
2. 5% branch profits tax on after-tax profits deemed repatriated (under the Treaty)

Effective combined rate: Approximately 25% on branch profits (21% + 5% × 79% ≈ 25%).

When a U.S. subsidiary pays dividends to its Turkish parent:

• Statutory withholding rate: 30%
• Treaty rate (U.S.-Turkey): 15%

Practical impact: A Turkish company operating through a U.S. C-corporation pays:

1. 21% U.S. corporate income tax on subsidiary profits, plus
2. 15% withholding tax on dividends paid to the Turkish parent

Effective combined rate: Approximately 33% on profits distributed as dividends (21% + 15% × 79% ≈ 33%).

Key insight: From a pure U.S. tax perspective, a branch is generally more tax-efficient than a C-corporation subsidiary for a Turkish company that plans to repatriate profits — primarily because the Treaty branch profits tax rate (5%) is lower than the Treaty dividend withholding rate (15%).

However, this analysis changes if:

• The U.S. business is expected to generate losses in early years (losses are more useful in a subsidiary structure if the Turkish parent cannot use U.S. losses directly)
• The subsidiary retains earnings rather than paying dividends (deferring the 15% withholding)
• The subsidiary is eventually sold (capital gains treatment may be more favorable than branch liquidation)

Turkish companies must also consider the Turkish tax treatment of U.S. branch income and subsidiary dividends:

Branch income: Turkish companies are generally taxed in Turkey on their worldwide income, including U.S. branch profits. A foreign tax credit is available for U.S. taxes paid, subject to Turkish limitations. Double taxation is generally avoided, but the interaction of Turkish and U.S. tax rules requires careful analysis.

Subsidiary dividends: Dividends received by a Turkish parent from a U.S. subsidiary may qualify for a participation exemption under Turkish tax law if certain ownership and holding period requirements are met. If the exemption applies, the dividends are not subject to Turkish corporate tax — making the subsidiary structure potentially more efficient from a Turkish tax perspective.

Because a branch is not a separate legal entity, the Turkish parent is directly and fully liable for all branch obligations — contracts, torts, employment claims, regulatory fines, and any other liabilities arising from U.S. operations.

This means:

• A judgment against the U.S. branch is a judgment against the Turkish parent
• Creditors of the U.S. branch can pursue the Turkish parent's assets (subject to enforcement limitations)
• Product liability, employment disputes, and regulatory violations in the U.S. directly expose the Turkish parent

For Turkish companies with significant U.S. operational risk (manufacturing, construction, consumer products, healthcare), the unlimited liability exposure of a branch structure is a serious concern.

A properly maintained U.S. subsidiary provides a liability shield — the Turkish parent's liability is generally limited to its investment in the subsidiary. U.S. creditors cannot reach the Turkish parent's assets simply because the subsidiary is insolvent.

Important caveats:

• The liability shield can be pierced if the subsidiary is not properly maintained (commingling of funds, failure to observe corporate formalities, undercapitalization, fraud)
• The Turkish parent may be required to personally guarantee subsidiary obligations (loans, leases, contracts) — which eliminates the practical benefit of the shield for those obligations
• Environmental liability and certain regulatory violations can sometimes reach parent companies

Best practice: Maintain the subsidiary as a genuinely separate entity — separate bank accounts, separate books, proper capitalization, board meetings, and no commingling of parent and subsidiary funds.

A foreign company operating a branch in the U.S. must:

• Register as a foreign corporation in each state where it does business (typically requires filing, paying a fee, and appointing a registered agent)
• File annual reports in each registered state
• Obtain an Employer Identification Number (EIN) from the IRS
• File Form 1120-F (U.S. Income Tax Return of a Foreign Corporation) annually
• Comply with state and local business license requirements

A U.S. subsidiary must:

• Incorporate or organize in a U.S. state (Delaware is most common for C-corporations; the operating state is common for LLCs)
• Register as a foreign entity in each state where it does business (other than the state of incorporation)
• Obtain an EIN
• File annual federal and state tax returns
• Maintain corporate records (minutes, resolutions, capitalization records)
• File beneficial ownership information with FinCEN under the Corporate Transparency Act

Compliance burden: Both structures require ongoing compliance. A subsidiary has somewhat more formation and governance overhead, but the difference is manageable for most businesses.

U.S. banks generally prefer to lend to U.S. entities rather than foreign branches. A U.S. subsidiary can:

• Open U.S. bank accounts more easily
• Obtain U.S. Small Business Administration (SBA) loans (if eligible)
• Access U.S. venture capital and private equity investment
• Issue equity to U.S. employees (stock options, restricted stock)

A branch can open U.S. bank accounts but may face more scrutiny and documentation requirements.

Some U.S. counterparties (customers, landlords, suppliers) prefer to contract with a U.S. entity rather than a foreign company. A U.S. subsidiary may be perceived as more stable, more accountable, and more familiar. For consumer-facing businesses or businesses requiring U.S. government contracts, a U.S. subsidiary is often essential.

Both branches and subsidiaries can employ U.S. workers. However:

• A U.S. subsidiary is the employer of record — cleaner for U.S. employment law compliance
• A branch employing U.S. workers means the Turkish parent is the employer — which can create complications for payroll, benefits, and employment law compliance

• The U.S. presence is temporary or exploratory (testing the market before committing to a full subsidiary)
• The U.S. business is expected to generate losses in early years that the Turkish parent can use against Turkish income
• The Turkish parent wants maximum control and simplicity without a separate U.S. entity
• The U.S. activity is low-risk (no significant product liability, employment, or regulatory exposure)
• The Turkish parent qualifies for the 5% branch profits tax rate under the Treaty and plans to repatriate profits

• The U.S. business involves significant operational risk (manufacturing, construction, consumer products, healthcare, financial services)
• The Turkish parent wants to limit liability exposure to its U.S. investment
• The U.S. business will retain earnings rather than repatriating profits immediately
• The U.S. subsidiary will seek U.S. financing, venture capital, or strategic partners
• The U.S. business will employ a significant U.S. workforce
• The Turkish parent may eventually sell the U.S. business (a subsidiary sale is structurally cleaner)
• The Turkish parent qualifies for the participation exemption on subsidiary dividends under Turkish tax law

For most Turkish companies entering the U.S. market with a genuine operating business, a U.S. LLC or C-corporation subsidiary is the preferred starting point because:

1. The liability shield protects the Turkish parent from U.S. operational risk
2. U.S. counterparties, banks, and employees are more comfortable with a U.S. entity
3. The structure is familiar and well-understood by U.S. advisors, banks, and regulators
4. Conversion from a branch to a subsidiary later is possible but involves tax costs — starting with a subsidiary avoids this

The branch structure is most appropriate for short-term, low-risk market testing or for Turkish companies with specific tax reasons to prefer branch treatment.

The branch vs. subsidiary decision is one of the most consequential structural choices a Turkish company makes when entering the U.S. market. The right answer depends on the interplay of U.S. and Turkish tax rules, liability considerations, operational needs, and long-term strategy.
