Sole Trader, SNC, SAS or SRL: Which Business Structure Should You Choose in Italy?

In a nutshell

When you set up a business in Italy, you have to choose how to structure it legally. The choice between a sole trader (ditta individuale), an SNC, an SAS, or an SRL is not just a formality — it changes how much personal risk you carry, how much tax you pay, and how much it costs to get started. The basic rule: the more protection you want for your personal assets, the more red tape and expense you'll face.

The difference that changes everything: unlimited vs limited liability

Before you look at costs, understand this concept. With unlimited liability (responsabilità illimitata) you are personally on the hook for business debts — your home, bank account, and car are all fair game. With limited liability (responsabilità limitata) you only risk the capital you put into the company.

The sole trader (ditta individuale) is the most exposed structure: you and the business are legally the same entity. If things go wrong, creditors can come after everything you own.

An SNC (Società in Nome Collettivo — a general partnership) works the same way but with multiple people: every partner is jointly and unlimitedly liable. If one partner can't pay, the others must cover. Before forming an SNC with anyone, make sure you trust that person completely.

An SAS (Società in Accomandita Semplice — a limited partnership) is a middle ground. There are soci accomandatari (managing partners) who run the business and bear full personal liability, and soci accomandanti (silent partners) who invest money and risk only what they put in. This structure suits anyone who wants outside capital without giving up management control.

An SRL (Società a Responsabilità Limitata — Italy's equivalent of a limited-liability company) protects you: partners are liable only for the capital they contributed. Your personal assets stay safe even if the company accumulates debts. You can set one up on your own (SRL Unipersonale — single-member LLC) with a minimum share capital of €1 — though if you go below €10,000 you must set aside 20% of annual profits as a legal reserve each year until you hit that threshold.

How each structure is taxed

The tax picture varies considerably depending on which form you choose, and that can make a real difference to what you actually take home each year.

As a sole trader you pay IRPEF (Italian personal income tax), which runs from 23% to 43% on a progressive scale. If you're just starting out or your revenue is below €85,000, you may qualify for the regime forfettario (Italy's flat-rate tax scheme for small businesses): a substitute tax of 15%, or even 5% in the first five years of activity. This is one of the most concrete advantages of the sole-trader structure.

With an SNC or SAS there is no company-level tax: profits flow through directly to the partners in proportion to their shares, and each partner pays IRPEF on their individual income. The flat-rate scheme is not available.

With an SRL the company itself pays IRES (Italy's corporate income tax) at 24% on profits, plus IRAP (Italy's regional business tax) at 3.9%. When you then distribute dividends to shareholders, those are subject to an additional 26% withholding tax on capital gains. Add it all up and the total tax burden on distributed profits reaches roughly 46%. The SRL only really makes sense financially if you reinvest profits back into the business rather than paying them out.

Which structure to choose — and when

Sole trader — go this route if you're a freelancer, a tradesperson, or a small retailer; your personal liability exposure is low; you want to get started quickly without a notary; and you want to take advantage of the flat-rate scheme. Typical Rome examples: web designer, photographer, plumber, hairdresser, software developer.

SNC — suitable when you have two or three partners with complete mutual trust, the business is family-run, and you want a simple structure. A notarised private agreement is enough — no public deed required. Examples: a father-and-son craft workshop, a small shop run by siblings.

SAS — useful when you need outside capital but don't want to hand over management control. The classic example is a parent funding a child's restaurant without getting involved in running it. The parent is the silent partner (risks only the invested money); the child is the managing partner (runs everything and bears full personal risk).

SRL — choose this when the business carries medium-to-high risk; you expect revenue above €100,000; you want to protect your personal assets; you need to attract investors; or you want to be able to transfer shares easily. Typical Rome examples: a full-service restaurant, a real-estate agency, an e-commerce business, an innovative startup.

How to set up in Rome — step by step

For a sole trader you don't need a notary. Register your Partita IVA with the Agenzia delle Entrate (Italy's tax-revenue agency) using form AA9/12, then submit the ComUnica filing through the Registro Imprese (Italy's official business registry) — you'll need a digital signature. ComUnica automatically notifies the Chamber of Commerce, INPS (Italy's social-security agency — pensions, unemployment, family benefits), and INAIL (Italy's workplace-injury insurance institute). You can be up and running in 1–3 days; total cost is €50–150 covering Chamber of Commerce fees and revenue stamps.

For an SNC or SAS you need at least a notary-authenticated private agreement. The notary then registers the company in the Registro Imprese via ComUnica. Timeline: 3–7 days; cost: €300–600.

For an SRL a full notarial public deed is required. Agree the articles of association and deed of incorporation with a notary, deposit the share capital at a bank (at least 25% if there are multiple shareholders, 100% if you're the sole shareholder), and the notary files for registration within 20 days. Then register your Partita IVA, INPS, and INAIL. Timeline: 7–15 days; notary fees alone: €1,500–3,000.

Mistakes to avoid

1. Opening an SRL just because it "sounds more professional". If your revenue is low, IRES, IRAP, and annual running costs — accountant, statutory accounts, Chamber of Commerce fees — can easily eat more than you'd save compared with paying personal IRPEF as a sole trader.
2. Underestimating unlimited liability in an SNC. When you join an SNC, you're personally on the hook for every other partner's debts with your own assets. If a partner causes a financial disaster, a creditor can come straight to you. This isn't a theoretical risk — it happens.
3. Paying an intermediary to register your Partita IVA. The application is free at the Agenzia delle Entrate. Anyone charging €100 or more just to fill in form AA9 is billing you for something you can do yourself — or that a CAF (free assistance office for tax forms and benefits applications) can help you with at no cost.

Special cases

If you've been working informally with someone without registering anything, Italian law already treats you as a società di fatto (a de facto partnership), taxed like an SNC. Regularise the arrangement as soon as possible to avoid problems.

If you're a foreign national living in Italy, you can set up any type of business structure. Non-EU citizens who are not resident in Italy are subject to reciprocity checks.

If you already have a sole tradership and want to convert to an SRL, you can do so via a notarial act of conferimento d'azienda (business transfer). Your client base transfers over; your Partita IVA changes.

Spouses can opt for the impresa familiare (family enterprise, art. 230-bis of the Italian Civil Code), which offers tax advantages and lower contributions compared with a standard company.
