Italian SRL vs. LLC vs. Ltd: what is the difference?
If you search for a “limited company in Italy” or “start up a company” without knowing Italian terminology, the structure you are usually looking for is an SRL (società a responsabilità limitata). It is Italy’s private limited-liability company.
An SRL is not simply an Italian translation of a US LLC. The three structures can all separate business debts from the owners’ personal assets, but they differ substantially in tax classification, formation formalities and capital rules. The most important distinction for a founder is this:
An Italian SRL is closer to a UK Ltd or a US C-corporation than to a default US LLC.
That comparison is about the ordinary tax treatment and corporate form, not a statement that the entities are interchangeable. The right choice depends on where the business operates, where it is managed, the founders’ tax residence, investors and the legal requirements of the target market.
The short answer
- Italian SRL: an Italian company taxed at company level, normally subject to IRES and IRAP; incorporation uses a public notarial deed.
- US LLC: a state-law entity whose default federal income-tax classification normally passes income through to its owner or members; it can elect corporate classification.
- UK Ltd: a private company limited by shares registered with Companies House and subject to UK Corporation Tax at company level.
The word “limited” describes liability protection. It does not tell you how profits are taxed, how the entity is formed or what filings are required.
1. Taxation: the decisive difference
Italian SRL: company-level taxation
An Italian SRL is taxed as a separate company for Italian corporate income-tax purposes. The standard IRES rate is 24%. The standard IRAP rate is 3.9%, subject to the regional and sector variations described in the tax rules. The combined figure of roughly 27.9% is only a headline calculation: IRES and IRAP have different taxable bases and are not simply two percentages applied to the same profit.
The company-level treatment is the starting point even when the shareholders are individuals or foreign companies. Dividends can trigger a separate layer of taxation or withholding when distributed, depending on the shareholder, residence, treaty and applicable relief. For the wider picture, see Italian taxes for a foreign-owned company.
This means that an Italian SRL does not use a US-style entity-classification election to become a disregarded entity or partnership for ordinary Italian corporate taxation. Italian tax residence and cross-border management still need a separate analysis: the place of effective management and ordinary management can matter, not only the registered office.
US LLC: default pass-through classification, with an election
The Internal Revenue Service treats a US LLC according to the number of members and elections made by the entity
- a single-member LLC is generally a disregarded entity for federal income tax, so its activities are reported by the owner;
- a domestic LLC with two or more members generally defaults to partnership classification;
- an eligible LLC can file Form 8832, Entity Classification Election, to be classified as a corporation instead.
The IRS therefore describes an LLC as a state-law entity that may be treated as a corporation, partnership or disregarded entity. “LLC” alone does not answer the tax question. The election and the owner’s status can change the filing obligations, and state, foreign and employment-tax rules may produce additional results.
A corporate election can make the comparison closer to a US C-corporation, but it is not the default. That is why a founder should not assume that an Italian SRL and a US LLC have the same tax profile simply because both names contain a liability limitation.
UK Ltd: Corporation Tax at company level
A UK private company limited by shares is a separate company for UK Corporation Tax. HM Revenue & Customs publishes different rates rather than one universal percentage: for the 2026 financial year, the small-profits rate is 19% for profits under £50,000 and the main rate is 25% for profits over £250,000, with marginal relief between those limits (subject to the rules and associated-company adjustments).
A UK Ltd therefore does not have the US LLC’s general entity-classification route to disregarded-entity or partnership treatment. The company pays Corporation Tax under the applicable rate rules; dividends and the shareholder’s own tax position are separate questions.
2. How each entity is formed
Italian SRL: public deed and Business Register filing
Under article 2463 of the Italian Civil Code, an SRL is incorporated by a public deed. The notary receives the deed and files it with the Italian Business Register. In eligible cases, the deed can be completed by videoconference, or a founder can use a properly prepared power of attorney abroad. These are not shortcuts around the deed: the notarial public-deed requirement remains the legal framework.
The guide to opening an SRL in Italy as a non-resident covers the codice fiscale, reciprocity checks, remote incorporation and post-incorporation filings. A foreign founder should also allow time for identity, beneficial-owner and banking checks, which are practical steps distinct from the statutory form of the incorporation deed.
US LLC: state filing, not a national incorporation
The United States has no single federal company-registration procedure for LLCs. The LLC is created under the law of a state. Delaware is a useful illustration: its LLC Act requires one or more authorised persons to execute and file a certificate of formation with the Secretary of State. The statute requires the company name, registered office and registered agent, and states that the LLC becomes a separate legal entity when the certificate is filed.
The internal rules are normally set out in an operating agreement (called a “limited liability company agreement” in Delaware law). The agreement may be written, oral or implied under Delaware’s statute, although a written agreement is generally prudent for governance, ownership and investor arrangements. There is no Italian-style public notarial deed requirement in the Delaware formation statute.
The exact filing, registered-agent, publication and annual-report requirements vary by state. “A US LLC” is therefore a family of state-law entities, not one uniform national form.
UK Ltd: Companies House online registration
A UK private company limited by shares can be registered online with Companies House. GOV.UK identifies the key steps: choose the company type and name, provide an official registered office, appoint at least one director, identify at least one shareholder, prepare the company documents and submit the registration information (including the SIC code and persons with significant control information).
The constitutional documents include a memorandum of association and articles of association. For an online filing, the memorandum is created automatically; the company can use model articles or submit its own articles. Companies House issues a certificate of incorporation once the application is accepted. This is an administrative registration process, not an Italian public deed before a notary.
3. Minimum capital and ownership funding
SRL: €1 is possible, but the form matters
The Italian Civil Code allows an ordinary SRL to have capital below €10,000 down to €1, subject to special rules on cash contributions and the strengthened legal reserve until the statutory threshold is reached. An SRLS is a simplified SRL with capital from €1 to €9,999, individual shareholders and standard-form articles.
An ordinary SRL can also be funded with a higher amount and allows more tailored governance and, in most cases, corporate shareholders and contributions in kind. The €1 figure is therefore a legal entry point, not a recommended operating budget or a promise that incorporation and early trading will cost €1.
UK Ltd: commonly £1 nominal share capital
UK guidance says that a share can have any value and gives £1 as an example of a low share value that limits the shareholder’s unpaid-share exposure to a reasonable amount. A founder will therefore commonly see a Ltd incorporated with one £1 ordinary share, but the company’s share capital is a legal structure rather than a measure of the business’s value or funding needs.
US LLC: no general federal minimum
There is no general US federal minimum capital amount for an LLC. State law controls. In Delaware, the formation statute lists the information required in the certificate and the membership statute allows a person to be admitted as a member without making or being obliged to make a contribution, unless the operating agreement provides otherwise.
That does not mean an LLC can operate without funding. Members may agree to contribute cash or property, investors and lenders may require committed capital, and state filing or annual fees still apply. It means that the legal formation threshold is not a universal paid-in-capital figure comparable to a share-capital rule.
4. Limited liability: similar headline, different details
At a high level, all three structures create a legal separation between the company and its owners
- Italian Civil Code article 2462 provides that, for an SRL’s obligations, the company is liable with its assets, subject to the statutory exceptions.
- Companies House describes a private company limited by shares as one where each member’s liability is limited to the amount unpaid on their shares.
- Delaware’s LLC Act provides that the LLC’s debts and liabilities are solely those of the LLC and that a member or manager is not personally liable solely because of that status, while allowing a member or manager to assume personal liability by agreement.
The practical protection is not absolute in any jurisdiction. A founder may still be exposed through a personal guarantee, unpaid subscribed capital, wrongful or fraudulent conduct, misuse of the separate entity, director or manager duties, tax and employment rules, or another statute. The tests and remedies for disregarding the entity or piercing the liability shield are jurisdiction-specific, so an adviser should review the actual state, Italian or UK facts rather than assume that “limited” means risk-free.
Final comparison table
| Dimension | Italian SRL | US LLC | UK Ltd (private company limited by shares) |
|---|---|---|---|
| Taxation | Separate company-level taxation; standard IRES 24% and standard IRAP 3.9% (different bases and possible variations). No ordinary pass-through election. | Default US federal treatment is generally disregarded entity for one member or partnership for multiple members; Form 8832 can elect corporate classification. State and cross-border rules vary. | Company-level Corporation Tax. For 2026, 19% small-profits rate under £50,000 and 25% main rate over £250,000, with marginal relief between thresholds, subject to the rules. |
| Formation | Public notarial deed under Civil Code article 2463, followed by Business Register filing; remote deed is possible when conditions are met. | State filing, such as a Delaware certificate of formation; operating agreement sets internal governance. No single federal formation process. | Companies House registration; registered office, at least one individual director, at least one shareholder, memorandum, articles, share-capital details and other registration information. |
| Minimum capital | Ordinary SRL can start at €1 under Civil Code rules; SRLS capital is €1–€9,999. Ordinary SRL has no statutory upper limit. | No general US federal minimum; state law and the operating agreement control. Delaware law can admit a member without a contribution. | Commonly one £1 share, but share value can be any amount; the £1 example is customary rather than a universal business-funding rule. |
| Liability | Normally limited to the company’s assets, subject to statutory exceptions and personal undertakings. | Normally the LLC alone owes its debts; a member or manager can separately agree to personal liability and other exceptions may apply. | Normally limited to the amount unpaid on the shareholder’s shares; guarantees and legal exceptions can create additional exposure. |
Which structure is closer to an Italian SRL?
For tax classification, an Italian SRL is closer to a UK Ltd or a US C-corporation than to a default US LLC: the SRL and Ltd are taxed as companies, while the ordinary US LLC classification is generally pass-through unless an election changes it.
For legal form, the comparison is never exact. A UK Ltd uses shares, directors and Companies House filings; an Italian SRL uses a notarial deed and Italian Civil Code governance; a US LLC is built under state law and can be highly contractual through its operating agreement.
If the business will actually operate in Italy, start with the SRL’s Italian incorporation and tax consequences rather than translating “LLC” word for word. Then test whether a foreign parent, branch, subsidiary or other structure is appropriate for the group. The non-resident SRL incorporation guide and foreign-owned company tax guide are the natural next steps, but neither replaces advice on the founder’s residence, management location, financing and treaty position.
