How Italian Companies Can Avoid Double Taxation When Expanding to the United States: A Guide to the U.S.-Italy Tax Treaty

Expert legal guidance for Italian businesses establishing U.S. subsidiaries and operations

Introduction: Understanding Double Taxation for Italian Companies in America

When Italian companies decide to expand their business to the United States, one of the most critical concerns is avoiding double taxation—being taxed on the same income by both Italy and the United States. Fortunately, the U.S.-Italy Income Tax Treaty (officially known as the Convention Between the Government of the United States of America and the Government of the Italian Republic for the Avoidance of Double Taxation) provides comprehensive protection and tax benefits for Italian businesses operating in America.

At Biazzo Law, PLLC, we help Italian companies navigate U.S. business expansion, entity formation, tax compliance, and international business law to ensure your American operations are structured efficiently from day one.

What Is the U.S.-Italy Tax Treaty?

The U.S.-Italy tax treaty, which entered into force in 1985 and was amended by protocol in 1999, is a bilateral agreement designed to:

• Prevent double taxation of income earned by Italian companies in the United States

• Reduce withholding tax rates on cross-border payments

• Establish clear rules for determining which country has primary taxing rights

• Prevent tax evasion while promoting international trade and investment

For Italian businesses opening U.S. subsidiaries, establishing branch offices, or conducting business activities in America, understanding this treaty is essential to optimizing your tax position and maintaining compliance with both Italian and U.S. tax authorities.

Key Provisions: How Italian Companies Avoid Double Taxation in the U.S.

1. The Permanent Establishment Rule

One of the most important concepts in the U.S.-Italy tax treaty is the "permanent establishment" (PE) rule. Under the treaty, Italian companies are only subject to U.S. corporate income tax on their business profits if they maintain a permanent establishment in the United States.

What constitutes a permanent establishment?

• A fixed place of business in the U.S. (office, factory, workshop)

• A construction site or installation project lasting more than 12 months

• An agent with authority to conclude contracts on behalf of the Italian company

  
  

Strategic insight for Italian businesses: If your Italian company conducts business activities in the United States without creating a permanent establishment—for example, through independent distributors or limited business trips—you may avoid U.S. corporate income tax on those profits entirely. However, proper structuring is critical, and mistakes can trigger unexpected U.S. tax obligations.

2. Reduced Withholding Tax Rates on Dividends

When a U.S. subsidiary pays dividends to its Italian parent company, the United States typically imposes a 30% withholding tax under domestic law. However, the U.S.-Italy tax treaty significantly reduces these rates:

• 5% withholding tax if the Italian parent company owns at least 10% of the voting stock of the U.S. subsidiary

• 15% withholding tax in all other cases

Example: If your Italian company owns 100% of a U.S. LLC taxed as a corporation or a U.S. C-Corporation, dividends paid to Italy will be subject to only 5% U.S. withholding tax, rather than 30%. The Italian parent can then claim a foreign tax credit in Italy for the U.S. tax paid, effectively eliminating double taxation.

3. Reduced Withholding on Interest Payments

Interest payments from a U.S. subsidiary to an Italian parent company are generally subject to 30% U.S. withholding tax. The treaty reduces this to:

• 10% withholding tax on most interest payments

• 0% withholding tax in certain circumstances involving bank loans and government-related financing

This treaty benefit makes it more tax-efficient for Italian companies to provide financing to their U.S. subsidiaries through loans rather than equity in certain situations, though careful attention must be paid to U.S. thin capitalization rules and earnings stripping limitations.

4. Royalty Payments: Significant Tax Savings

Royalties paid by a U.S. subsidiary to an Italian parent company for the use of intellectual property (patents, trademarks, copyrights, know-how) face reduced withholding rates under the treaty:

• 5% or 8% withholding tax depending on the type of intellectual property (compared to 30% under U.S. domestic law)

For Italian companies licensing technology, brands, or proprietary processes to their U.S. operations, these treaty benefits represent substantial tax savings.

5. Foreign Tax Credit System

Even when income is taxed by both countries, Italian companies can avoid double taxation through the foreign tax credit mechanism. Under the treaty:

• Italy allows Italian companies to credit U.S. taxes paid against their Italian tax liability on the same income

• The United States similarly allows foreign tax credits for Italian taxes paid

This ensures that the same income is not effectively taxed twice at full rates in both jurisdictions.

Entity Structure Matters: Choosing the Right U.S. Business Entity for Italian Companies

The U.S. entity structure you choose for your American operations significantly impacts how the tax treaty applies:

U.S. C-Corporation

• Treated as a separate taxable entity in the U.S.

• Profits taxed at the U.S. corporate level

• Dividends paid to Italian parent subject to treaty-reduced withholding (typically 5%)

• Clear treaty benefits and well-established rules
  

U.S. LLC (Limited Liability Company)

• Can be taxed as a corporation, partnership, or disregarded entity

• If treated as a partnership or disregarded entity, income "flows through" to Italian parent

• Tax treaty application can be complex; requires careful analysis

• May offer flexibility for certain business structures

Branch Office

• Not a separate legal entity; extension of Italian company

• All profits attributable to the U.S. branch are subject to U.S. tax

• Subject to branch profits tax (additional 5% under treaty, vs. 30% under U.S. law)

• Simpler structure but less liability protection

Critical consideration: Choosing the wrong entity structure can result in higher taxes, compliance complications, and missed treaty benefits. Italian companies should work with experienced U.S. business attorneys who understand both American corporate law and international tax treaties.

Compliance Requirements: Claiming Treaty Benefits

To benefit from the U.S.-Italy tax treaty, Italian companies must comply with specific documentation and reporting requirements:

IRS Form W-8BEN-E

Italian companies receiving U.S.-source income (dividends, interest, royalties) must provide U.S. withholding agents with Form W-8BEN-E (Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting).

This form:

• Certifies that the Italian company is a resident of Italy for tax purposes

• Claims the benefit of reduced withholding rates under the treaty

• Must be updated periodically and when circumstances change

Limitation on Benefits (LOB) Provisions

The U.S.-Italy tax treaty includes "Limitation on Benefits" provisions designed to prevent treaty shopping. To qualify for treaty benefits, Italian companies must meet certain tests, such as:

• Publicly traded test: Company is publicly traded on a recognized Italian exchange

• Ownership and base erosion test: Company is substantially owned by Italian residents and meets income requirements

• Active trade or business test: Company is engaged in active business operations in Italy

U.S. Tax Return Filing

Italian companies with U.S. operations may need to file:

• Form 1120-F (U.S. Income Tax Return of a Foreign Corporation)

• Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation)

• State-level tax returns depending on where business is conducted

Failure to comply with these requirements can result in loss of treaty benefits, penalties, and increased IRS scrutiny.

State Tax Considerations for Italian Companies

While the U.S.-Italy tax treaty addresses federal taxation, Italian companies must also navigate U.S. state taxes:

• State income taxes vary by state (ranging from 0% to over 10%)

• States determine tax obligations based on "nexus" (sufficient connection to the state)

• Treaty benefits generally do not apply at the state level

• Some states offer tax incentives for foreign investment

  
  

Strategic planning: Many Italian companies incorporate in Delaware for its favorable corporate law but maintain operations in other states. Understanding state tax obligations is essential to avoiding unexpected liabilities.

Common Mistakes Italian Companies Make (And How to Avoid Them)

Mistake #1: Failing to Properly Structure the U.S. Entity

Choosing the wrong entity type or failing to make appropriate tax elections can result in unfavorable tax treatment and lost treaty benefits.

Mistake #2: Not Filing Required Forms

Missing filing deadlines for Forms W-8BEN-E, 5472, or 1120-F can trigger automatic penalties and loss of treaty protection.

Mistake #3: Creating Unintended Permanent Establishment

Sending Italian employees to work in the U.S. without proper planning can inadvertently create a permanent establishment, triggering U.S. tax obligations.

Mistake #4: Inadequate Transfer Pricing Documentation

Transactions between Italian parent companies and U.S. subsidiaries must be at arm's length. The IRS scrutinizes related-party transactions and can adjust income allocations.

Mistake #5: Overlooking State and Local Tax Obligations

Focusing solely on federal taxes while ignoring state income tax, sales tax, and local business taxes can lead to significant unexpected liabilities.
