How Should Foreign Investors Choose Between an S.A., S.R.L. and S.A.S. in Argentina?

A foreign investor may own all the shares of an S.A. in Argentina, subject to sector-specific restrictions and ownership eligibility rules.

In this guide, we compare the S.A., S.R.L. and S.A.S. in Argentina on ownership, capital, management, supervision, cost and timeline, and match each form to the investor profile it serves best.

What Are the S.A., S.R.L. and S.A.S. in Argentina?

The S.A., S.R.L. and S.A.S. are Argentina's three most common corporate vehicles, and each limits owners' liability to the capital contributed. The S.A. and S.R.L. are governed by Companies Law No. 19,550 of 1972, as amended, while the Entrepreneurs' Law No. 27,349 added the S.A.S. in 2017 to speed up business formation.

Foreign shareholders may hold 100% of any of the three, subject to sector-specific restrictions and applicable ownership eligibility rules. The practical differences lie in who can own the company, who runs it and how much supervision it attracts.

1. Sociedad Anónima (S.A.)

The S.A. is a share company run by a board of directors (directorio). It needs at least two shareholders unless formed as a single-owner S.A.U., and it suits large groups, regulated sectors and businesses that may raise capital or list later. Its shares are generally transferable, although the bylaws may impose limits on transfers.

2. Sociedad de Responsabilidad Limitada (S.R.L.)

The S.R.L. is Argentina's limited liability company. It runs on quotas rather than shares, caps membership at 50 partners and is managed by one or more gerentes instead of a board. Most small and family businesses choose it.

3. Sociedad por Acciones Simplificada (S.A.S.)

The S.A.S. is a simplified share company created in 2017. A single shareholder — individual or company, local or foreign — can incorporate one, subject to Article 39 restrictions, including restrictions on control by certain companies covered by Article 299, and its bylaws can be tailored far more freely. Startups and solo market entries use it most.

What Are the Key Differences Between the Three Structures?

Ownership limits, capital minimums, management bodies and statutory supervision divide the three forms — the essentials are summarised below.

The three forms differ on five practical dimensions: who may own them, how much capital they need, who runs them, who supervises them and how easily owners exit.

When several investors are involved, the S.A.'s transferable shares and the S.R.L.'s partner controls matter most. A solo founder can consider an S.A.S. or a single-owner S.A.U., while an S.R.L. needs at least two partners at formation.

1. Ownership and Capital Requirements

An S.A. generally needs at least two shareholders, although an S.A.U. can have one. An S.R.L. needs two to 50 partners at formation, and an S.A.S. can have one or more shareholders. As of 4 November 2026, under Article 186 of Companies Law No. 19,550, as updated by Decree 209/2024, a new S.A. needs at least ARS 30 million in capital. An S.R.L. has no equivalent general statutory minimum; Article 40 of Law No. 27,349 sets the S.A.S. minimum at two statutory monthly minimum wages. Confirm current requirements with the relevant registry before filing.

2. Management and Control

The S.A. is run by a board of directors, with at least one director. Under Articles 255 and 299 of Companies Law No. 19,550 and Ministry of Justice Resolution 10/2024, at least three are required when capital reaches ARS 2 billion or other Article 299 grounds apply, subject to the exception for S.A.U. status alone. The S.R.L. is run by one or more gerentes, who may be partners or outsiders. The S.A.S. is the most flexible: its bylaws can adopt board-like or manager-like governance at will.

3. Supervision and Disclosure

As of 4 November 2026, under Articles 284 and 299 of Companies Law No. 19,550 and Ministry of Justice Resolution 10/2024, an S.A. with capital of at least ARS 2 billion must have statutory supervision; other Article 299 grounds, including S.A.U. status, also apply. An S.R.L. reaching that capital threshold must appoint a síndico or supervisory board under Article 158. Supervision is optional for an S.A.S. under Law No. 27,349. All three must still prepare annual financial statements.

How Long Does Registration Take in Argentina?

Timelines vary by registry and filing completeness. As of 4 November 2026, IGJ advertises S.A.S. registration in 72 hours and offers a five-business-day urgent route for S.A.s and S.R.L.s when filings have no observations; actual times can vary.

Timing depends on the registry: in Buenos Aires, the Inspección General de Justicia (IGJ) supervises company registration, while each province runs its own. Under IGJ General Resolution 11/2026, company formation generally no longer requires a professional prequalification opinion, although exceptions may apply. The S.A. route is subject to registry review and requires publication of a prescribed notice in the Official Gazette. Both S.R.L.s and S.A.s publish an incorporation notice containing the information prescribed by Article 10. In Buenos Aires, an S.A.S. is filed through the government's digital system; actual registration times vary with the filing and registry.

The company obtains its tax identification number (CUIT) from ARCA; depending on the registry process, it may be assigned with registration. ARCA is the Agencia de Recaudación y Control Aduanero, which replaced the former authority AFIP under Decree 953/2024, published on 25 October 2024. The company can then open a local bank account. Foreign shareholders add documentation steps, which we cover below.

Obtain jurisdiction-specific quotes for registry fees, Official Gazette notices, notary or signature certification, translations and legalisation, and professional advice. In Buenos Aires, IGJ says the S.A.S. constitution fee includes publication; signature certification at IGJ costs extra. Confirm current amounts before filing.

Which Entity Fits Which Foreign Investor?

Large groups and some regulated businesses may choose an Argentina S.A., joint ventures and family firms an S.R.L., and solo founders or fast-moving startups an S.A.S.; sector rules determine which forms are permitted.

Match the form to your shareholder count, sector and exit plan. The three profiles below cover the decisions we most often see in practice, and the same logic applies to subsidiaries and holding structures.

1. When the S.A. Works Best

Choose an Argentina S.A. when you plan to raise capital, list, or operate in a regulated sector where an S.A. is an approved form; banking and insurance laws also permit certain other forms. Generally transferable shares can make joint ventures with many investors easier to unwind, although the bylaws may limit transfers.

2. When the S.R.L. Fits Better

Choose an S.R.L. when a small team wants control and low disclosure — family businesses, holdings and two-party joint ventures. Quota transfers may be made by public instrument or by private instrument with authenticated signatures, and registry filing makes them effective against third parties.

3. When the S.A.S. Is the Fastest Route

Choose an S.A.S. when speed and flexibility dominate — a single founder testing the market, or a subsidiary that must be live quickly. Its shares are designed for private companies, so founders aiming at a stock-market listing typically convert to an S.A. first.

Does the Entity Choice Change Your Taxes in Argentina?

No — the same corporate income tax schedule applies to all three forms, so governance, disclosure and cost should drive the choice, not the tax rate.

Corporate income tax applies uniformly to S.A.s, S.R.L.s and S.A.S.s, and the standard value added tax (VAT) rate runs at 21%. What differs is administration: every company must register with the tax authority, file periodic returns and keep compliant books. Cross-border groups also face transfer pricing rules on related-party dealings, and beneficial-ownership reporting obligations for companies have tightened in recent years.

The principle travels to other markets. In Singapore, the Inland Revenue Authority of Singapore applies a flat 17% corporate income tax to all companies, local or foreign-owned — entity form there, as in Argentina, changes governance rather than the headline rate. Rates and filing rules shift, which is why most investors pair registration with international accounting services support so nothing is missed.

How Should Foreign Investors Prepare Before Filing?

Preparation, not paperwork, shortens an Argentine incorporation. Four steps settle the decision before anything is filed, and each one is cheap to fix early and expensive to fix later. Choosing an international service provider can help coordinate advice across jurisdictions.

Step 1: Define Ownership and Exit Rights Early

Fix shareholder count, veto rights and exit terms first. A two-investor structure with a funding plan already points to the S.A.; a solo entry can use an S.A.S. or an S.A.U.

Step 2: Confirm Current Registry Requirements

Minimum capital, director counts and document rules come from registry resolutions that change periodically. Verify current figures with the registry in your chosen province before drafting bylaws.

Step 3: Prepare Apostilled Documents for Foreign Shareholders

Foreign corporate owners typically need apostilled proof of existence, translated powers of attorney and certificates of good standing. A 2023 deregulatory decree also limited the guarantees registries may demand from foreign parent companies.

Step 4: Model Governance and Conversion Options

Draft bylaws with the end state in mind — board seats, transfer restrictions and conversion paths. Argentine law permits transformation between forms, so a fast S.A.S. entry can later become an S.A. before fundraising.

Conclusion

The S.A., S.R.L. and S.A.S. all deliver limited liability and can permit full foreign ownership in Argentina, subject to sector-specific restrictions and applicable ownership eligibility rules; what changes is ownership flexibility, capital formality, supervision and speed. Match the form to your shareholder count, sector and exit plan before filing, then budget for the differences in setup time and ongoing obligations.
