SAS vs SA vs trust in Uruguay: which one is best for you
Public Limited Company (SA)
The Uruguayan Corporation (Sociedad Anónima) has a very formal and relatively long incorporation process, which takes between 3 and 5 months, and requires a minimum of 2 shareholders, either individuals or legal entities, domestic or foreign.
To speed up the process, it is common in Uruguay to acquire pre-incorporated companies that have no activity and have not yet held their first shareholders’ meeting nor appointed the first Board of Directors. In that case, the transfer of shares and the appointment of the First Board of Directors takes about two weeks, with the limitation regarding the company name. However, in Uruguay companies can register a “trade name”, which will be the one used commercially, including on invoices (as long as the legal name appears somewhere). It is also possible to amend the bylaws to change the legal name, although this is a process with significant cost and takes approximately 3 months.
The Corporation may have a single shareholder and a single Director, who may be the same person, either individual or legal entity, and does not require residence in Uruguay.
The S.A. is not an offshore company, but according to Uruguayan tax regulations, activities, income, and assets located outside Uruguay are, in principle, exempt from taxes in Uruguay.
Main taxes:
Corporate Control Tax (ICOSA). Every Uruguayan S.A. pays a fixed minimum annual tax of approximately USD 700 (ICOSA) from the moment of its incorporation, even if it has no activity. This tax is paid monthly (approx. USD 60/month).
Corporate Income Tax (IRAE). The income tax is called IRAE, with a rate of 25%, calculated on net income after deducting all operating and non-operating expenses.
Income from services provided abroad, including commissions, to non-Uruguayan residents, or investments made outside Uruguay, are in principle not taxed by IRAE in Uruguay. Likewise, for the calculation of taxable net income, only expenses incurred in Uruguay and those abroad directly linked to the generation of taxable income are deductible as costs.
In the case of international trading operations (purchase and sale outside Uruguay, without the physical entry of the product into the country), companies are taxed IRAE (25%) on a deemed base equivalent to 3% of the gross margin (sale price minus cost of goods). That is, if the S.A. buys a product at 80 and sells it at 100, it will pay 0.75% of the gross margin; in the example: (100 – 80) × 0.25 × 0.03 = 0.15 of tax.
Another relevant consideration is that once the company begins to generate taxable income (even if the effective rate is low, as in the case of offshore trading), it must make monthly advance payments of income tax of approximately USD 180. At year-end, once the final calculations are made, these advances are considered final payments, even if the determined tax is lower. In this sense, the advances operate as a minimum income tax.
In the case of a company that will not have operations in Uruguay, even if it receives profits from abroad (interest, dividends) or income from services provided entirely outside Uruguay and to non-Uruguayan residents, it will not pay either advance payments or income tax.
Dividend Tax (ID). On the other hand, the distribution of dividends derived from taxed income is subject to Dividend Tax (ID), at a rate of 7% on distributed dividends. Profits from abroad that are not taxed by IRAE are also not subject to ID. If the recipient of the profits is a foreign resident, even if they have not been taxed by IRAE, they will still be subject to the 7% rate as long as it can be credited against taxes payable in their country of tax residence.
In the case of international trading, since the taxable income is equivalent to 3% of the gross margin, only that 3% is subject to ID. In the previous example, where the taxable income is 0.6 (3% of 20), 7% will be paid on 0.6, that is 0.042, equivalent to 0.21% of the gross margin.
The total between IRAE and Dividend Tax for international trading amounts to approximately 0.96% of the gross margin.
Net Worth Tax (IP). Another tax to consider is Net Worth Tax (IP), which taxes assets located in the country, minus liabilities in Uruguay, at a rate of 1.5%. The balance available in a Uruguayan bank account, for example, constitutes an asset subject to IP; however, it is easy to reduce the taxable base by lowering the bank balance at the fiscal year-end.
Assets located abroad (equity participations, real estate, bank accounts, etc.) are not subject to this tax.
Value Added Tax (VAT). Domestic sales of goods and services are subject to VAT, with companies acting as withholding agents. Companies invoice adding 22% VAT and, at the same time, pay VAT on local purchases. Monthly, they must remit to the tax authority the difference between VAT charged on sales and VAT paid on purchases.
Exports and operations carried out outside the country are not subject to VAT.
The Uruguayan company may have bank accounts anywhere in the world and participate in other companies in any country.
The Uruguayan S.A. must file annual financial statements within 4 months following the end of the fiscal year, which can be set at the end of any month (determined at the time of incorporation), and settle the corresponding taxes.
Iruleguy Asociados will be responsible for making monthly advance payments of ICOSA, IP, VAT, and IRAE (when applicable), as well as preparing financial statements and annual tax filings for these taxes.
Other legal obligations of Uruguayan companies: register all Directors with the Public Registry and tax authorities, and also register the names of shareholders and beneficial owners with the Central Bank of Uruguay. This information may only be disclosed by court order or upon a justified request from the DGI.
The Uruguayan company is also required to use electronic invoicing. We include the costs associated with registration and use of electronic invoicing.
Simplified Joint-Stock Company (SAS)
This type of company in Uruguay aims to facilitate the development of entrepreneurship, seeking to expedite the incorporation of corporations by reducing formalities, costs and incorporation times.
The SAS grants greater freedom to the shareholders' will than the traditional SA (for example, it allows for the establishment of different classes of shares with differentiated rights and benefits, as well as limiting the transfer of shares, among other possibilities). It also modernizes the convening and operation of General Shareholders' Meetings (allowing, for example, for them to be held abroad or by videoconference), and permits the existence of a single shareholder, among other flexibilities.
The differentiating aspects to consider in tax matters are :
The SAS does not pay ICOSA.
Legal representatives of SAS companies must make social security contributions in Uruguay, regardless of whether they receive remuneration for their role (contributions to the Social Security Bank). This means that even if the representative is the owner and does not receive a salary, they must still make a minimum contribution. We estimate the cost of social security contributions to be approximately USD 250 per month.
In contrast, in a SA (public limited company), directors do not make social security contributions if they do not receive a salary from the company.
For income generated within Uruguayan territory, which is taxable, this corporate structure can opt for a "fictitious" income tax, which is established in stages according to what is billed annually (Rates range from 3% to 15%).
Companies with annual revenues of less than 4 million UI (indexed units, currently approximately USD 685,000) are exempt from dividend distribution tax.
In all other respects, what has already been explained for the SA applies, including the form of taxation.
Trust
A trust (fideicomiso) in Uruguay is a contract by which a person (the settlor) transfers ownership of certain assets/rights to a trustee, so that the trustee manages those assets for a specific purpose, for the benefit of a beneficiary (or beneficiaries). Uruguayan law establishes that the transferred assets constitute a separate allocated estate; that is, they are not commingled with the assets of the trustee, the settlor, or the beneficiary.
It is important to structure it with experienced professionals who know how to draft it and include clauses to ensure proper protection and provide peace of mind to clients. Irrevocability (and anticipating in the drafting that it cannot cease to be so), the definition of beneficiaries, replacement of parties, operation of business activities, powers, potential “conflicts among beneficiaries,” incapacity, and applicable law are some of the most important clauses.
Trusts are often combined with holding or operating companies (S.A., S.A.S., or other jurisdictions).
In asset and corporate structures, trusts are frequently chosen because:
They avoid having to go through a probate process.
They provide confidentiality.
They ensure continuity during the settlor’s lifetime and after death, avoiding disruptions, liquidity issues, etc.
They allow protection of minor and/or vulnerable heirs and help resolve complex family matters.
They allow coordination of succession planning.
They eliminate issues that arise when assets were omitted from a will or acquired after it was drafted.
They provide a high degree of asset protection against third parties, whether legitimate heirs or not.
They make it possible to avoid limitations inherent in forced heirship regimes.
In principle, they do not need to be modified when a person relocates to another country.
Asset protection / functional shielding: trust assets are “segregated” (separate estate), reducing risks of contamination from personal issues of the trustee/settlor/beneficiaries (with nuances depending on the case).
Succession and governance: they allow setting rules for management, income distribution, replacement of beneficiaries, conditions, etc., all predefined in the contract.
Flexibility: they do not require a board of directors like an S.A. (the core of the structure is the contract + the trustee), and they can be designed for very specific objectives.
Unlike an S.A., a trust is not a company: it is a contractual legal arrangement.
It is normally implemented by contract (and, depending on the asset, may require additional formalities).
If real estate is involved, it generally requires a public deed and registration to transfer ownership to the trustee (since there is a transfer of title to the trust estate).
If the contract does not establish a term, the law sets a maximum legal term of 30 years.
The typical parties are: Settlor (who contributes assets/rights); Trustee (who receives fiduciary ownership and manages the assets); Beneficiary(ies) (who receives the benefits/results); Remainderman (who receives the assets at the end, if so structured — it may be the beneficiary themselves, heirs, etc.). In many cases there is also a financial advisor, and the role of a “protector” (protecting the settlor), as ancillary roles.
The law generally allows the trustee to be either an individual or a legal entity (with legal capacity).
In the case of financial trusts or when the trustee acts as a “professional” trustee, there are specific requirements and registrations before the Central Bank of Uruguay (BCU), with additional requirements.
Common types:
Administrative trust: the trustee manages assets (real estate, shares, portfolio, rights) and executes governance/distribution rules.
Guarantee trust: assets are contributed as collateral for an obligation; it often has a differentiated tax treatment in certain scenarios.
Financial trust (securitization / capital markets): used to issue securities, raise funds, and structure financing; it is the most regulated (BCU/capital markets).
Although a trust does not have corporate legal personality, it is generally treated as a taxable subject (similar to a company), with obligations before the tax authority (DGI) and, where applicable, withholding and reporting requirements; similar to an S.A., plus the ICOSA tax.
FAQ - Frequently Asked Questions
-
What is the main difference between an SAS and an S.A. in Uruguay?
The SAS (Simplified Stock Company) is more agile, cost-effective, and flexible — it can be incorporated in 7 to 15 business days and does not pay ICOSA. The S.A. (Corporation) takes 3 to 5 months to be incorporated from scratch but does not need to make social security contributions (approximately USD 260 monthly) for a director or administrator (although this can be avoided by hiring a director service through our firm). The SAS also has an option that is generally more tax-efficient for businesses operating within Uruguay and does not pay taxes on distributions up to approximately USD 865,000 annually. For most operational structures and personal holdings, the SAS is the most efficient option in 2026.
-
How much does it cost to incorporate a company in Uruguay?
An SAS has an incorporation cost of approximately USD 1,700 to USD 2,500. A new S.A. takes months, although it can be acquired pre-incorporated for a cost of USD 4,700 - 5,200 and in just 2 weeks. A trust starts from USD 2,500 and can exceed USD 6,000 depending on the complexity of the agreement. These costs are in addition to annual maintenance costs: accounting, taxes, and compliance.
-
What taxes does a company pay in Uruguay if it operates abroad?
Foreign-source income is exempt from IRAE in Uruguay — for SAS, S.A., and trusts. For international trading operations, the effective tax burden is approximately 0.96% on the gross margin (+ 0.75% on income + 0.21% on dividend distribution). Income generated in Uruguay is subject to IRAE at 25% on net income, with an optional deemed tax regime for SAS, which is tiered and ranges between 3% and 15% of revenue.
-
When is it advisable to choose a trust instead of a company?
A trust is advisable when the main objective is advanced asset protection, succession planning with specific rules, or the formal separation of assets from legal or family risks. Unlike an SAS or S.A., a trust does not have legal personality — it is a contract that creates a separate allocated estate, providing a higher level of asset protection. Its greater complexity and cost are justified when the assets to be protected are significant.
-
Can a foreigner incorporate a company in Uruguay without residing in the country?
Yes. SAS, S.A., and trusts can be incorporated by foreign individuals or legal entities without the need for residency in Uruguay. The process can be carried out remotely with the appropriate documentation. Iruleguy Asociados supports the entire process end-to-end, including powers of attorney, compliance, and bank account opening.
-
What structure is best for an international family holding?
For family holdings with multiple assets across different countries, the Uruguayan S.A. is the most common option due to its stronger international banking recognition and shareholder anonymity (the shareholder registry before the Central Bank of Uruguay is confidential and only disclosed by court order). For holdings with complex succession objectives, a trust can complement or replace the S.A., depending on the case.
-
What is the difference between a Uruguayan fideicomiso and an international trust?
A fideicomiso is the civil law structure of Uruguay — regulated by local law, with registration before DGI and BCU when applicable. A trust is the Anglo-Saxon (common law) structure, with greater international flexibility and privacy in jurisdictions such as BVI, Cayman Islands, or New Zealand. Both are used for asset protection and succession planning, but the Uruguayan fideicomiso has advantages in simplicity and cost, while the international trust is preferred when greater privacy is required or when operating across multiple jurisdictions.
