LLC vs C-Corp for Italian Founders: Which US Entity Is Right for You?
Italian founders building a US business face a familiar European pattern: Italy's tax treatment of a US LLC is unfavourable, and the C-Corp is generally the better choice for founders with serious US ambitions. This guide covers the Italian-specific considerations.
The core difference
An LLC is a pass-through entity by default — no US corporate tax, profits flow to owners. A C-Corp is a separate taxable entity — 21% US corporate tax, then dividend withholding on distributions. C-Corps are the standard for venture-backed companies.
The Italian tax dimension
Italy taxes Italian residents on worldwide income. The treatment of a US LLC under Italian tax law creates specific problems.
The LLC transparency problem: Italy generally treats a US LLC as a transparent entity (similar to an Italian società di persone), meaning Italian tax applies to the LLC's profits directly, even if not distributed. The US also taxes the LLC's income at the individual level. The result is a risk of double taxation, with limited treaty relief. The US-Italy tax treaty (in force since 1984, updated 1999) has provisions for hybrid entities, but the interaction is complex.
The C-Corp advantage: Italy treats a US C-Corp as an opaque entity (similar to an Italian SpA or SRL). Italian tax on corporate profits is deferred until you take a dividend or salary. The US-Italy treaty reduces dividend withholding to 5% for qualifying corporate shareholders (holding 25%+ of the C-Corp) and 15% for individuals.
The SRL holding structure: Many Italian founders use an Italian SRL (Società a Responsabilità Limitata) as the holding entity that owns the US C-Corp shares. This structure — Italian SRL → US C-Corp — can be tax-efficient, particularly if the SRL qualifies for the Italian participation exemption (PEX) on dividends received from the US C-Corp. If this is your situation, the US entity should be a C-Corp.
When to choose an LLC
- Simple service business, no retained earnings, no fundraising plans
- You have confirmed with an Italian cross-border tax adviser that the transparent treatment does not create double taxation in your specific case
- You want the lowest administrative overhead
When to choose a C-Corp
- You plan to raise venture capital or angel investment
- You want to issue stock options
- You want to retain profits in the US entity
- You are using or plan to use an Italian SRL as the holding entity
- You want treaty-protected dividend treatment

What Keystone Bridge recommends
For most Italian founders building a scalable business, the C-Corp is the better choice. The treaty protection and clean equity structure outweigh the double-taxation cost. For founders running a simple service business, the LLC can work — but only with an Italian cross-border tax adviser confirming the structure first.
