The 5 most common mistakes when setting up a company in Argentina

Argentina remains one of the most attractive economies in South America. With a solid domestic market, highly qualified professionals, and opportunities in sectors such as energy, O&G, technology, services, and agribusiness, many international companies look to establish a presence in the country. However, entering the Argentine market can become a quagmire if not properly planned. Through my experience advising foreign businesses, I have identified several recurring issues that can be avoided with the right guidance.

Here are the five most common mistakes when setting up a company in Argentina — and how to prevent them.

1️⃣ Failing to choose the right corporate structure

Selecting the proper legal entity is one of the most critical steps. The most common options are:

Sociedad Anónima (S.A.) – Corporation
Sociedad de Responsabilidad Limitada (S.R.L.) – LLC
Sociedad por Acciones Simplificada (S.A.S.) – Simplified Corporation
Branch of a foreign company

Each structure carries different implications regarding liability, capital requirements, and administrative formalities. A common mistake is attempting to replicate the parent company’s structure without taking into account its particular characteristicas in Argentina.

👉 Tip: define the structure according to your business model, investor profile, and long-term operational goals.

2️⃣ Overlooking the prior registration of the foreign shareholder (Article 123, Companies Law)

If a foreign company intends to act as a shareholder in an Argentine entity, it must first register with the Public Registry of Commerce (IGJ) under Article 123 of the Argentine Companies Law (LGS). This registration proves the company’s legal existence, principal place of business, and corporate decision to invest in Argentina. Without it, the participation cannot be validly registered.

Typical mistakes include:

Missing apostilles or consular legalization.
Incomplete or untranslated bylaws.
Failure to appoint a local legal representative with domicile in Argentina.

👉 Tip: start the Article 123 registration early and ensure all documents are properly legalized and translated. Proper preparation saves significant time and avoids costly registry delays.

3️⃣ Underestimating procedural timelines and formal requirements

Even with all documents ready, the registration process can take longer than expected, especially bearing in mind the previous paragraph. The IGJ strictly reviews every filing, and even minor inconsistencies can result in observations. Additionally, legalization, translation, and coordination with notaries, banks and tax authorities can extend the timeline.

👉 Tip: plan ahead and rely on experienced local counsel who understands both the law and the practical workflow of each institution involved.

4️⃣ Failing to coordinate corporate, tax, and banking processes

A frequent challenge for foreign investors is the lack of synchronization between corporate registration, tax identification, and banking setup. Each institution — IGJ, ARCA, and local banks — requires documentation that depends on the previous step, so delays in one area can stall the entire project. For instance, opening a corporate bank account often requires a CUIT (tax ID), which cannot be obtained until the company is properly registered; meanwhile, some payments or investments may need to flow in before that.

👉 Tip: manage all corporate, tax, and banking procedures under a single coordinated plan, ideally with one local advisor overseeing the sequence. Parallel preparation of documents and early communication with banks significantly shortens the time to full operational capacity.

5️⃣ Neglecting the appointment of a local director

The majority of the local company’s directors must reside in the country. In addition to being a legal requirement, this ensures proper legal representation and registration with the authorities. Failing to appoint a resident director can block the company’s ability to be registered, act, open bank accounts, or sign official documents.

👉 Tip: designate a qualified local director early in the process. Once the company is set up, it may be replaced by a designated foreign person who -in the meantime- will have cleared her migration visa.

🧭 Conclusion

Setting up a company in Argentina can be straightforward with proper preparation and integrated advice. Avoiding these five mistakes will ensure a smooth and compliant market entry.
