How an Italian Company Sets Up Operations in the United States

Italian companies entering the U.S. market typically do so by forming a new U.S. entity — most commonly a corporation or a limited liability company (LLC). The process itself is not complex, but the choices made during setup have significant implications for taxation, reporting, and the ongoing relationship between the U.S. subsidiary and the Italian parent.

This article provides a practical overview of what the process looks like, what decisions need to be made, and where we most frequently see Italian groups run into difficulties.

1. Choosing the Right Entity Type

The first and most consequential decision is the choice of entity. For Italian-owned businesses, the most common options are:

• C-Corporation — the default for most foreign-owned U.S. subsidiaries. It provides limited liability, is familiar to Italian parent companies, and has a well-established tax and reporting framework. Profits are taxed at the entity level.
• LLC taxed as a corporation — offers more flexibility in governance and operations while being treated as a corporation for U.S. tax purposes. This is increasingly common for smaller operations.
• Branch office — in some cases, an Italian company may operate directly in the U.S. without forming a separate entity. This creates a different set of tax obligations and is generally less common for ongoing operations.

The choice depends on factors including the nature of the U.S. activities, expected revenue levels, the number of employees, the parent company's reporting requirements, and treaty considerations. We frequently see Italian groups make this decision based solely on legal advice without considering the tax and accounting implications — which are often the more significant long-term factors.

2. State of Incorporation

A U.S. entity must be incorporated in a specific state. Delaware is the most popular choice for foreign-owned companies due to its well-developed corporate law and business-friendly court system. However, if the company's operations are concentrated in a single state — say, New York or Florida — incorporating in that state may simplify compliance.

It is important to understand that incorporating in one state does not limit the obligation to register and pay taxes in other states where the company has a physical or economic presence (nexus). This is a point that many Italian groups initially overlook.

3. Federal and State Tax Registration

Once the entity is formed, several registrations are required:

• EIN (Employer Identification Number) — the U.S. equivalent of a tax identification number. Required for tax filings, bank accounts, and hiring employees.
• State income tax registration — in the state(s) where the company operates.
• Sales tax registration — if the company sells taxable goods or services, it must register in each state where it has nexus. Since the 2018 Wayfair decision, economic nexus thresholds mean that even remote sellers may have obligations in multiple states.
• Payroll registration — if the company will have U.S. employees.

4. Opening a U.S. Bank Account

This step is often more difficult than Italian groups expect. U.S. banks have strict compliance requirements for foreign-owned entities, and the documentation and verification process can take several weeks. Typical requirements include the entity's formation documents, EIN confirmation, identification of beneficial owners, and sometimes a physical meeting.

We generally recommend starting the banking process early, as delays here can hold up the entire operational setup.

5. Intercompany Agreements

This is perhaps the most important — and most frequently neglected — step. From the moment the U.S. entity begins operating, transactions between the Italian parent and the U.S. subsidiary need to be documented and priced at arm's length.

Common intercompany arrangements include:

• distribution or resale agreements
• management service agreements
• intellectual property licensing
• intercompany loans
• cost-sharing arrangements

These agreements must be in place before transactions occur — not retroactively. The IRS scrutinizes intercompany pricing for foreign-owned U.S. entities, and Form 5472 requires annual disclosure of all reportable transactions with foreign related parties.

6. Accounting and Reporting Setup

Italian groups are accustomed to Italian GAAP or IFRS. The U.S. subsidiary will typically need to maintain books under U.S. GAAP, while also providing reporting packages to the Italian parent in a format compatible with group consolidation.

Decisions that need to be made early include:

• chart of accounts aligned with both U.S. requirements and group reporting
• accounting software selection
• monthly reporting cadence and format
• year-end alignment (Italian groups often use a December 31 fiscal year, which typically aligns with U.S. requirements)

In our experience, setting up the accounting framework correctly in the first few months saves significant time and cost later — particularly when the group auditors begin requesting U.S. reporting packages.

7. First-Year Compliance Calendar

The first year of operations brings several compliance deadlines that Italian groups are often not fully prepared for:

• federal corporate income tax return (Form 1120) — due by April 15, with extension to October 15
• Form 5472 — reporting transactions with foreign related parties, filed with the tax return
• state income tax returns — due dates vary by state
• sales tax returns — monthly, quarterly, or annually depending on the state
• annual report filings — most states require an annual report to maintain good standing
• payroll tax returns — quarterly (Form 941) and annual (W-2, W-3)

Common Mistakes We See

After working with numerous Italian groups on U.S. setup projects, the mistakes we encounter most frequently are:

• choosing the entity type based on legal considerations alone, without analyzing the tax implications
• not establishing intercompany agreements before operations begin
• assuming that state tax obligations only arise in the state of incorporation
• underestimating U.S. bookkeeping and reporting requirements
• expecting Italian accounting practices to translate directly to U.S. GAAP
• delaying the EIN and bank account process, which holds up everything else

Closing Observations

The mechanics of forming a U.S. entity are relatively simple. What makes the difference — particularly for Italian-owned businesses — is the quality of the decisions made during setup and the coordination between legal, tax, and accounting advisors.

Getting the structure, intercompany framework, and compliance calendar right from day one avoids the most common and most expensive corrections we see in the first two to three years of operations.
