Starting a company does not begin with a form.
It begins by defining which legal structure your business actually needs. Choosing correctly from the start can facilitate growth, reduce conflicts between partners and prepare the company to receive investment.

01 What does it mean to start a company in Argentina?

A business can carry out commercial activities without necessarily being incorporated as a company. However, when there are partners, when the goal is to separate personal assets from business assets, or when a structure designed for growth is needed, incorporating a company may be an appropriate option.

A company incorporated under Argentine law is a legal entity separate from its partners or shareholders. The incorporation instrument must be registered with the relevant Public Registry corresponding to the company's registered address.

The key idea: incorporating a company is not simply a matter of filling out a form. It involves legally designing the structure of a business.

02 What type of company do you need?

One of the most common mistakes is choosing a company structure solely because of its cost or because someone else used the same type of entity.

The right question
What structure does my business need?

Among the most commonly used alternatives in Argentina are the SAS, SRL, SA and SAU.

03 SAS, SRL or SA: which one is right for you?

There is no universal answer. The choice should take into account the number of partners, the business activity, assets, investment, management and projected growth.

01 · SAS

Simplified Joint-Stock Company

It can be particularly attractive for entrepreneurs, startups and certain projects seeking a flexible structure.

02 · SRL

Limited Liability Company

A traditional structure for small and medium-sized businesses with a relatively closed group of partners.

03 · SA

Joint-Stock Company

A share-based structure that may be suitable for more complex business organizations.

04 · SAU

Single-Member Joint-Stock Company

An alternative provided for under Argentina's General Companies Law when one person needs to incorporate a joint-stock company.

Tipo Structure Can be single-member Typical profile
SAS Shares Yes Startups / ventures
SRL Quotas No SMEs / closed ownership groups
SA Shares No Companies / investors
SAU Shares Yes Single-member joint-stock company
Do not choose based only on speed or price. The right structure today can prevent an expensive reorganization when the business grows.

04 Define who the partners or shareholders will be

Before drafting the bylaws or company agreement, it is necessary to define who will participate in the company and what percentage each person will hold.

However, the ownership percentage should not be the only issue considered.

What happens if a partner wants to sell?

It is advisable to establish mechanisms to prevent conflicts and organize a potential transfer.

What happens if a partner stops working?

A partner's departure may require specific rules agreed upon in advance.

What happens if an investor appears?

The structure should make it possible to properly accommodate a future investment.

What happens if there is a conflict?

Anticipating deadlock scenarios can be crucial to protecting the continuity of the business.

05 Choose the company name

The company needs a name that identifies it and complies with the requirements of the relevant jurisdiction.

Before definitively choosing a name, it is also advisable to review company-name availability, existing trademarks, trade names, domain names and social media accounts.

Important: the fact that a name is available for company incorporation does not necessarily mean it is also available as a trademark.

06 Registered address and corporate headquarters

The company must have a registered address within the relevant jurisdiction. Its corporate headquarters must also be determined in accordance with applicable regulations.

The headquarters is particularly important because legal effects may arise there and certain notices may be served there.

07 Define the corporate purpose

The corporate purpose determines which activities the company will carry out. This point can be much more important than it may appear.

A poorly designed corporate purpose can create problems when the company wants to add new activities, enter into certain contracts, obtain permits, work with banks or bring in investors.

Think beyond day one. The corporate purpose should be designed by considering not only what the company does today, but also how it may evolve.

08 Determine the share capital

Another fundamental point is determining how much capital the company will have and how it will be contributed.

Capital may be contributed in cash or, where regulations allow, through certain assets that can be valued.

Common mistake
Share capital should not be determined solely with the goal of paying the minimum possible amount.

There should be a reasonable relationship between the legal structure and the business activity to be carried out.

09 Define who will manage the company

The incorporation process also requires determining who will be responsible for the management and representation of the company.

Management

Determine who manages the company and for how long.

Representation

Establish who may act on behalf of the company before third parties.

Powers

Define the scope of the managers' or directors' powers.

Documentation

Comply with acceptance-of-office requirements and other applicable formalities.

10 Draft the bylaws or company agreement

The incorporation instrument establishes the fundamental rules governing the operation of the company.

It may regulate the company name, registered address, corporate purpose, duration, capital, ownership interests, management, representation, operation of corporate bodies, transfer of interests and distribution of profits, among other matters.

Standard bylaws ≠ ideal bylaws. A standard model may simplify the process, but it does not necessarily address the specific needs of every business.

11 Sign and certify the documentation

The incorporation instrument must comply with the formalities applicable to the company type and jurisdiction.

Depending on the structure, different signing and certification methods may apply.

12 Publish the legal notice

Depending on the type of company, the corresponding publication must be made in the Official Gazette.

This step is part of the formal incorporation process and should not be confused with final registration.

13 File the company with the Public Registry

The company must be filed with the relevant registration authority.

En CABA, el organismo competente es la General Inspectorate of Justice (IGJ).

The required documentation depends on the type of company. Therefore, there is no single incorporation file applicable to every business.

14 How long does it take to incorporate a company?

There is no single timeframe for all companies. Timing depends on the company type, jurisdiction, filing method, documentation and any observations or requirements.

Attention
The existence of an expedited procedure for certain companies does not mean that every business in Argentina can be incorporated in five days.

The jurisdiction and company type are decisive.

15 How much does it cost to start a company?

The cost depends on the type of company, jurisdiction and incorporation method.

Professional fees
Registration fees
Signature certification
Official Gazette publication
Legalizations and documentation
Corporate and accounting books

16 Obtain a CUIT and tax registration

Company incorporation does not end with registration. The company must also complete its tax obligations.

Depending on the activity and jurisdiction, the relevant tax registrations must be assessed.

Legal incorporation + tax planning: both processes should be coordinated from the outset.

17 Open a business bank account

Once the company has been incorporated and the necessary documentation obtained, the process of opening a bank account in the company's name can begin.

The bank may request documentation relating to the bylaws, registration, CUIT, company officers, beneficial owners, business activity, source of funds and partner or shareholder documentation.

18 What happens after incorporating the company?

One of the most common mistakes is thinking the work ends when the registered bylaws are received.

In reality, that is where the company's corporate life begins.

Libros societarios

Maintain the company's corporate documentation properly.

Financial statements

Comply with the applicable accounting obligations.

Minutes and decisions

Properly document corporate decisions.

Tax obligations

Keep the company's tax status up to date.

19 Mistakes to avoid

ERROR 01

Choosing based only on price

The cheapest option today may become inconvenient if the company grows.

ERROR 02

Copying someone else's bylaws

Two companies can have completely different needs.

ERROR 03

Failing to regulate the relationship between partners

Many conflicts begin because no one agreed in advance on what would happen if one partner wanted to leave.

ERROR 04

Failing to think about the future

The structure should account for investment, growth and changes in the business.

20 Can a foreigner start a company?

Yes. Argentine law contemplates the participation of foreign individuals and legal entities in certain company structures, although additional requirements may apply.

The required documentation will depend on the chosen structure and the specific circumstances of the foreign investor.

If there are foreign partners or investors, it is advisable to design the structure before beginning the incorporation process.

21 Can I start a company without traveling to Argentina?

En determinados casos es posible organizar el proceso sin que todos the interested parties have to travel physically to Argentina.

The specific possibility will depend on the company type, jurisdiction, available documentation, signing and certification methods, and whether any participant acts through a power of attorney.

22 What is the best company structure for a business?

No existe una sociedad universalmente mejor. The choice depends on the project.

SAS

Puede ser adecuada para determinados emprendimientos que buscan flexibilidad.

SRL

Puede ser conveniente para empresas con una estructura with a more closed ownership structure.

SA

Puede resultar apropiada para proyectos con una estructura basada en acciones.

SAU

It may be an alternative when a single person needs a joint-stock company.

The decision should arise from the needs of the business. Not simply from a comparison of prices.

23 Checklist for starting a company
