Cross-Border Tax Basics

Overview

Transfer pricing, permanent establishment, and treaty positioning

Cross-border tax planning is not simply about minimizing tax rates. It is about ensuring that the company's legal structure, operational conduct, contracts, intellectual-property ownership, and intercompany payments are aligned.

Three concepts are central to nearly every international company entering the United States: transfer pricing, permanent establishment, and treaty positioning.

Transfer Pricing

Transfer pricing governs transactions between related companies located in different jurisdictions.

Common intercompany transactions include:

Tax authorities generally expect related companies to transact on arm's-length terms. This means the price should resemble the price that unrelated parties would have agreed to under comparable circumstances.

• Management services
• Software development
• Research and development
• Sales support
• Marketing
• Customer service
• Intellectual-property licensing
• Product distribution
• Intercompany loans
• Cost reimbursements

Why Transfer Pricing Matters

Assume a foreign parent owns the technology and a U.S. subsidiary performs sales and marketing.

The group must determine:

A company should not assign nearly all profit to one entity while another entity performs substantial functions and assumes meaningful risks without appropriate compensation.

• Which entity contracts with customers
• Which entity records revenue
• Which entity bears market risk
• Which entity owns customer relationships
• How the U.S. subsidiary is compensated
• Whether the U.S. subsidiary earns a service fee, commission, or distribution margin

Transfer-Pricing Documentation

A defensible framework commonly includes:

Intercompany agreements should reflect actual conduct. A contract stating that the U.S. subsidiary performs limited support services will be less persuasive if the U.S. team independently negotiates contracts, sets prices, controls customer relationships, and bears commercial risk.

• Description of each legal entity
• Functional analysis
• Assets used by each entity
• Risks assumed by each entity
• Intercompany agreements
• Pricing methodology
• Comparable-company or transaction analysis
• Financial calculations
• Consistent invoicing practices

Permanent Establishment

Permanent establishment is a treaty concept used to determine whether a company has a sufficient taxable presence in another country.

A foreign company may face U.S. tax exposure when its activities create a U.S. trade or business or a permanent establishment under an applicable treaty.

Potential risk factors may include:

The analysis is fact-specific. Simply stating that an employee is engaged only in marketing or preparatory activity may not resolve the issue if the employee's actual conduct is central to revenue generation.

• Fixed office or place of business
• Employees working regularly in the United States
• Executives conducting core business activities in the United States
• Personnel habitually concluding contracts
• Dependent agents
• Long-term projects
• Warehousing or operational facilities
• Substantial founder activity within the United States

Remote Work and Founder Activity

Cross-border founders often create tax exposure unintentionally.

Examples include:

These situations can affect corporate tax, payroll, individual tax residency, state nexus, and treaty claims.

• A founder spends significant time in the United States while continuing to manage the foreign company.
• A foreign employee works permanently from a U.S. state.
• A salesperson regularly negotiates and closes contracts.
• A U.S.-based executive exercises strategic control over the group.
• The foreign parent uses the U.S. founder's home as an operational base.

Treaty Positioning

The United States has income-tax treaties with many countries. Treaties may reduce withholding taxes, define permanent establishment, establish residency rules, and provide mechanisms for resolving double taxation.

Treaty benefits are not automatic.

A company may need to establish:

Treaty planning should not be reduced to selecting a country with an attractive withholding rate. Tax authorities may examine whether the entity has genuine substance, decision-making authority, employees, functions, assets, and business purpose.

• Residency in a treaty country
• Beneficial ownership
• Satisfaction of limitation-on-benefits provisions
• Appropriate documentation
• Eligibility for reduced withholding
• Consistency between legal form and tax treatment

Withholding Taxes

Cross-border payments may be subject to U.S. withholding requirements.

Potentially relevant payments include:

The applicable rate may depend on domestic law, treaty eligibility, documentation, payment classification, and recipient status.

Companies should collect appropriate tax forms and evaluate withholding before making payments.

• Dividends
• Interest
• Royalties
• Certain service payments
• Payments to foreign contractors
• Proceeds involving U.S. real-property interests

Intellectual Property

Intellectual-property ownership is one of the most consequential cross-border tax decisions.

Questions include:

Moving intellectual property after it has accumulated significant value can create substantial tax exposure.

Founders should address intellectual-property ownership before major U.S. fundraising, commercialization, or restructuring.

• Which entity legally owns the intellectual property?
• Which entity funded its development?
• Where were development activities performed?
• Which entity employs the engineers?
• Which entity controls development risk?
• Are licenses documented?
• Has intellectual property been transferred?
• Was a valuation required?

State and Local Tax

Federal tax analysis is only part of the picture.

A company may create state tax obligations through:

Potential obligations include:

Each state applies its own rules.

• Employees
• Offices
• Inventory
• Contractors
• Customers
• Sales volume
• Property
• Remote work
• Economic nexus thresholds
• Income or franchise tax
• Sales and use tax
• Payroll withholding
• Unemployment insurance
• Gross receipts tax
• Local business taxes

Cross-Border Tax Operating Checklist

Before U.S. expansion, determine:

The central principle is alignment. The legal documents, accounting records, invoices, employee activity, customer contracts, and management decisions should tell the same economic story.

• Parent and subsidiary tax residency
• Ownership of intellectual property
• Intercompany transaction types
• Transfer-pricing method
• Permanent-establishment exposure
• Treaty eligibility
• Withholding obligations
• State tax nexus
• Sales-tax responsibilities
• Founder tax residency
• Payroll requirements
• Reporting of foreign accounts and ownership
