Setting up foreign subsidiary

International Expansion and Foreign Entities: Taxes, Permanent Establishment, and Structuring explains that setting up a foreign subsidiary involves local incorporation, registration, tax registration, and creates a separate taxable entity that ordinarily limits permanent establishment exposure compared with operating through a branch; the OECD Model Tax Convention Article 5 defines a permanent establishment (PE) as a "fixed place of business". Setting up a subsidiary typically triggers local corporate tax filing and transfer pricing obligations, while a branch can create immediate PE risks and expose home-country profits to foreign taxation under the host state's rules. Local capital requirements vary by jurisdiction and some countries require director residency or minimum capital.

Mechanically, the choice between a foreign subsidiary and a branch is evaluated using legal tests and tax frameworks such as the OECD Model Tax Convention, BEPS Action 7 guidance, and domestic corporate law; common tools include advance pricing agreements (APAs) and local transfer pricing documentation under the OECD Transfer Pricing Guidelines. Cross-border tax structuring must consider permanent establishment rules and double taxation treaties to assess withholding tax exposure and tax residency for companies, while international business structure decisions interact with thin-capitalization rules, VAT registration, and local substance requirements that determine treaty benefits and treaty entitlement, and include jurisdictional risk scoring.

The important nuance is that incorporation location does not eliminate permanent establishment exposure and often creates parallel compliance risks; a concrete example is a U.S. software firm that incorporates a local subsidiary for sales but uses local agents who habitually conclude contracts, which under Article 5 could produce a dependent agent PE even though the entity is a separate taxpayer. Many founders confuse branch vs subsidiary simply as liability choices, overlooking foreign entity taxation, withholding taxes on cross-border payments, and transfer pricing compliance obligations that require intercompany contracts, pricing policies, and documentation prior to first cross-border invoicing, and tax authorities often focus on substance when assessing treaty entitlement.

Practical next steps for a founder or in-house counsel include performing a PE risk assessment using the OECD Article 5 tests, reviewing applicable double taxation treaties and local withholding rates, deciding between branch versus subsidiary based on liability, compliance, and tax outcomes, documenting intercompany services and transfer pricing policies, and seeking APAs or rulings where exposure is material. Early registration, local tax IDs, payroll setup, and timely transfer pricing documentation reduce audit risk. Engaging local counsel and tax advisors to maintain books according to local GAAP or IFRS is common. This page contains a structured, step-by-step framework.
