Definition of an S.p.A.

A joint-stock company is a corporation governed by the Italian Civil Code (Article 2325 et seq.). The entity type suits established businesses, often medium- to large-scale, seeking funding.

When forming an S.p.A., note that this legal structure keeps its assets clearly separate from those of its shareholders. The equity holders’ liability is capped at the amount contributed.

Creating one divides the entity’s equity into stock units that owners can trade easily, making the model well suited to enterprises that plan to expand or draw investors.

This structure is often used by large-scale enterprises, late-stage startups, or enterprises seeking to access the financial markets.

Requirements for establishing an S.p.A.

To establish an S.p.A. in Italy, several formal and funding conditions apply; the sections below outline them in detail.

Minimum share capital

The minimum share capital required to incorporate an S.p.A. is €50,000. At that time, at least 25% of the sum must be paid in (or 100% if a sole shareholder).

This factor directly affects the costs of setting one up, making this form less accessible than some alternatives, such as the limited liability business (S.r.l.).

Articles of incorporation and bylaws

To understand how to establish an S.p.A., it is useful to know it is mandatory to draw up articles of incorporation as a public deed before a notary. The deed must contain the following:

• Company name
  
• Corporate purpose
  
• Share capital
  
• Number and value of the shares
  
• Governance system
  

Shareholders

To form an S.p.A., there can be one or more shareholders, who could be either natural persons or legal entities (such as other companies). Such flexibility is one of the notable advantages of incorporating an S.p.A., particularly for complex business ventures or transactions involving institutional investors.

If the entity has a sole shareholder (a single-member corporation), the full stock amount is payable at the time of creation. This factor directly affects the costs of its formation, but it provides greater protection against creditors.

Another point to consider is share transferability: parties creating an S.p.A. can set limits or conditions on share transfers in the bylaws, but, in general, shares transfer freely. As a result, adding new investors over time and increasing equity becomes easier.

Registration with the Business Register

An S.p.A. comes into existence when the Chamber of Commerce enters it in the Business Register for the relevant territory. Solely from this point on does the company acquire juridical personality and become fully operational.

After the parties sign the deed, the public official handling the act files the articles of incorporation and the governing rules. Registration usually takes place within a few days. Still, it is a necessary step for anyone intending to form an S.p.A., as without completion of the filing, the entity does not officially exist.

Filing also involves assigning a company registration number and a tax code/value-added tax (VAT) number, which are needed for starting business operations, issuing invoices, and managing relationships with customers and suppliers.

Characteristics of an S.p.A.

When deciding to form an S.p.A., it is important to understand the distinctive characteristics of this enterprise model, which make it ideal for organized, growth-oriented businesses.

Limited liability

One of the primary reasons for choosing this corporate form is the limited liability of shareholders. Each one is solely liable for the entity’s liabilities up to the amount contributed, without risking personal assets. That protection serves as a valuable safeguard for ventures that require substantial investment or entail higher exposure. In practice:

• The personal assets of shareholders are separate from those of the company
  
• Creditors might seek recourse against the company’s capital
  
• The business risk is limited to the investment made
  

Furthermore, the arrangement increases the brand’s appeal to outside investors, who can invest without assuming unlimited liability. Limited liability is one of the defining features that distinguish S.p.A.s from partnerships.

Capital divided into shares

When parties create an S.p.A., they divide the authorized funding into shares of equal value that represent the shareholders’ equity stakes. The system gives owners added flexibility in handling ownership, as shares can trade easily, subject to any limits outlined in the governing rules. As a result, it becomes possible to:

• Facilitate the entry of new investors
  
• Conduct capital increases in a more structured manner
  
• Simplify the transfer (in whole or in part) of your equity stake
  
• If necessary, prepare the company for a future public listing
  

Additionally, shares can fall into different categories (for instance, with varying economic or management rights), thus providing extra tools for shaping corporate governance.

Public deed

Another point to note when creating an S.p.A. is the need for a public deed drawn up by a certified official. This step ensures the legal validity of its formation and shows the bylaws and articles of incorporation comply with all applicable rules. Specifically, the notary’s role is to:

• Verify the identity of the shareholders and their intention to incorporate the company
  
• Ensure that the articles of incorporation comply with the law
  
• Certify the formal validity of the entire process
  

Corporate bodies

The organizational structure is one of the central factors for anyone planning to establish an S.p.A. It, in fact, has a defined governance system consisting of various bodies with specific functions. The principal ones are:

• Shareholders’ meeting, which votes on key decisions (financial statements, appointment of directors, amendments to the bylaws)

• The administrative body (board of directors or sole director), responsible for the company’s day-to-day operations

• Supervisory body (board of statutory auditors or statutory auditor), which oversees proper oversight and compliance with regulations

This framework ensures stronger transparency and stricter oversight than other corporate models. When incorporating an S.p.A., defining the governance structure is a necessary step that affects the company’s efficiency and the balance of power within it.

Transparency and inspections

Its establishment entails stricter transparency and monitoring requirements than alternative legal forms. S.p.A.s must, in fact, follow specific rules when drafting their financial statements and, in many cases, have them audited. In operational terms, this translates to:

• Mandatory preparation and filing of annual financial statements
  
• A potential statutory audit
  
• Periodic inspections by supervisory bodies
  
• Greater formalization of administrative processes
  

These obligations require a more organized operating approach, but they also enhance the organization’s reliability and strengthen its market reputation.

Advantages of an S.p.A.

Choosing to establish an S.p.A. means adopting a framework designed to support growth, attract investment, and operate in competitive environments. Let us take a closer look at its primary benefits.

Access to capital

One of the main advantages of those who decide to structure one is the ability to raise funds in a clearer manner than with other types of companies. Dividing the capital into shares enables the firm to bring in new investors—both individual and institutional—without radically altering its corporate framework.

In practical terms, this means being able to:

• Issue new shares to finance growth
  
• Attract investment funds or venture capital
  
• Gain access to regulated markets in the future
  

Market credibility

The incorporation of an S.p.A. helps strengthen the company’s image, enhancing its credibility with stakeholders, business partners, and financial institutions. Its layered framework and tighter disclosure duties often signal soundness and reliability. For those who choose to establish an S.p.A., this means:

• Easier access to bank financing
  
• Better terms when negotiating with suppliers and partners
  
• Greater trust from customers and investors
  

Scalability

If the goal is to expand the enterprise in an orderly way, creating an S.p.A. is a solid choice. It supports expansion in scale and organizational complexity. Thanks to its structure, you can:

• More easily manage growth and internationalization initiatives
  
• Restructure the corporate framework without substantial operational impacts
  
• Plan mergers, acquisitions, or strategic partnerships
  

Corporate continuity

An S.p.A. is well suited to long-term ventures, where continuity and stability are foundational to success. Another significant benefit for those who decide to form one is, in fact, business continuity: it exists independently of its shareholders, and the transfer of shares does not affect its existence. As a result:

• The entry or departure of shareholders does not interrupt business operations
  
• Ownership transfers in a gradual, efficient way
  
• The company maintains stability over time, including during changes in governance
  

How much does it cost to form an S.p.A.?

If you are wondering how much it costs to form an S.p.A., bear in mind that the cost can vary depending on numerous factors, but in general, it is quite high compared to other corporate models. First and foremost, you need to consider a minimum share capital of €50,000, plus notary fees (approximately €2,000–€4,000), registration taxes, Chamber of Commerce fees, and legal and fiscal consulting costs. Overall, the initial cost can exceed €55,000.

How much tax does an S.p.A. pay?

An S.p.A. in the country is primarily subject to two levies: IRES (Italian Corporate Income Tax) and IRAP (Italian regional tax on productive activities). IRES is levied at a rate of 24% on profits, whereas IRAP generally ranges from 3.9% to 4.82%, depending on the region and sector.

In addition to these main taxes, it might also be subject to further forms of taxation, such as VAT on commercial transactions and levies on dividends distributed to shareholders. The overall fiscal burden, therefore, depends on several factors, including the amount of profits, geographic location, and the nature of the business.

Difference between S.p.A.s and partnerships limited by shares

When considering whether to form an S.p.A., it is helpful to compare it with alternative but similar entity types, such as the partnership limited by shares (S.a.p.a.). Although both are corporations with equity divided into shares, they differ substantially in structure and governance.

Investors

The primary distinction concerns the types of investors. In an S.p.A., all shareholders have limited liability to the extent of their contribution. An S.a.p.a., however, has two categories:

• General partners: These have unlimited liability and are responsible for management.
  
• Limited partners: These contribute to the capital but have limited liability.
  

Governance

The distinction has a profound impact on governance. Upon incorporation of an S.p.A., day-to-day direction is entrusted to bodies appointed by the shareholders’ meeting (such as the board of directors), which ensures a separation between ownership and oversight. In S.a.p.a.s, by contrast, management authority is concentrated in the general partners, which makes the setup less flexible and heavily dependent on specific individuals.

For those looking to establish an S.p.A., this translates into greater investor appeal and easier corporate restructuring. S.a.p.a.s, on the other hand, are not widespread today and are used primarily in specific contexts where certain managing partners wish to maintain stable control.

What is the difference between S.r.l.s and S.p.A.s?

The primary distinction between S.r.l.s and S.p.A.s lies in their governing frameworks, size, and funding allocation.

In S.r.l.s, ownership interests use quotas, and management can run operations through a simpler, and more adaptable model, which suits small and medium-sized enterprises. In S.p.A.s, ownership funding uses transferable stock units, and the framework is more layered, with required oversight bodies and tighter disclosure standards.

Let us examine the main differences below:

How to incorporate an S.p.A.

Let us now take a practical look at how to incorporate an S.p.A., breaking down the primary steps involved in setting one up in Italy:

• Definition of the business plan
  Before proceeding with the incorporation of an S.p.A., it is useful to clarify the business model, the corporate purpose, and the growth objectives. At this stage, it is also helpful to assess the financial requirements, the shareholder structure, and the initiative’s economic viability.

• Drafting the articles of incorporation and bylaws
  The articles of incorporation and the bylaws define the rules under which the company operates: governance, shareholder rights, procedures for transferring shares, and the handling of strategic decisions.

• Payment of share capital
  To form an S.p.A., at least 25% of the share capital (or 100% in the case of a sole shareholder) must be deposited into a restricted account. This step is necessary to provide evidence of initial financial stability and proceed with the incorporation.

• Notarial deed
  An S.p.A. must be formed by means of a public deed executed before a notary, who verifies the validity of the transaction and certifies the documents. The notary plays a core role in ensuring that the company complies with applicable legislation.

• Registration with the Business Register
  The final step in understanding how to incorporate an S.p.A. is registration with the Business Register. Solely upon entry does the entity acquire legal status and can begin operating officially in the market.
