In recent years Uruguay has become a regional leader in renewable energy, with an electricity mix that is over 95% clean in typical years. This is no accident: it is the result of a state policy combining legal stability, specific tax incentives and a clear regulatory framework that attracts local and international investment. If you are considering how to set up a company in Uruguay in the renewable energy sector — whether to develop wind, solar or biomass projects, energy management or related technical services — this article guides you step by step through the key corporate, tax and operational aspects of setting up and running your company with legal certainty and tax efficiency.

The context is favourable: Uruguay has an Investment Law (Law 16,906) with significant tax benefits for projects declared promoted, a Free Zone regime that exempts income and wealth taxes, and mechanisms for self-generation and distributed generation. But to use these tools it is essential to choose the right company type, plan the tax structure from the start and meet all requirements with the relevant bodies: DGI, BPS and, in certain cases, the Ministry of Industry, Energy and Mining (MIEM) and its National Energy Directorate (DNE). Here is how.

Choosing the Corporate Structure for Renewable Energy

The first step is to define which legal structure suits the type of project, investment volume, number of partners and whether there will be institutional investors or bank financing. The types of companies in Uruguay most used in this sector are four, each with its own features.

Corporation (SA) for Large-Scale Projects

The corporation (SA) is the traditional structure for large renewable generation projects, especially when there are several investors, capital is to be raised or structured bank financing is sought. The SA can issue different classes of shares, makes it easy for partners to enter and exit and is widely recognised by banks and institutional investors. It is incorporated before a notary, with its articles reviewed by the AIN, a board of directors (or sole director) and formalities such as minutes books and shareholders’ meetings. The SA pays the corporate control tax (ICOSA), a fixed annual amount, although certain promoted or free zone activities may be exempt.

Limited Liability Company (SRL) for Medium-Sized Projects

The SRL is a flexible and cheaper alternative in terms of running costs. It does not pay ICOSA, management is simpler (no board required) and transfers of quotas are more controlled than in an SA. It suits family businesses, small groups of partners or medium-sized projects where frequent changes in ownership are not expected. It is incorporated before a notary and registered with the General Registry Office (DGR), and then with DGI and BPS.

Simplified Joint Stock Company (SAS) for Agile Projects and Startups

The SAS is the most modern and flexible company type, governed by Law 19,820. It can be incorporated quickly by private document (including online through the “Empresa en el Día” system), allows partners to enter and exit easily and does not pay ICOSA. It is ideal for entrepreneurs who want to incorporate quickly and cheaply, technology startups in the energy sector (energy management software, energy trading platforms, energy efficiency projects) and smaller or early-stage projects. The SAS issues shares and can later transform into an SA if the project grows. You can even buy a ready-made SAS to start operating within hours.

Sole Proprietorship for Professionals and Services

A sole proprietorship suits professionals (engineers, technicians, consultants) who provide services to the energy sector without developing large investment projects. It is simple to set up and cheap to run, but it does not separate the owner’s personal assets from the business: the owner is personally liable. Its ability to scale is limited and it is not attractive to outside investors.

In short, to decide which legal structure to choose, analyse the type of activity, the project size, financing needs and the growth horizon.

Specific Tax Benefits for Renewable Energy

Uruguay offers a range of tax incentives designed to attract investment in renewable energy. They can significantly reduce the tax burden and improve project returns, but obtaining them requires meeting formal requirements, submitting projects to the relevant bodies and staying compliant throughout the benefit period.

Investment Law: IRAE and Wealth Tax Exemptions

Investment Promotion Law 16,906 allows projects declared promoted to obtain partial exemptions from corporate income tax (IRAE, general rate 25%) and from Wealth Tax on the investment, among other benefits. To obtain them, the company must submit a project to the Investment Law Application Commission (COMAP) with feasibility studies, an investment plan, a schedule and the expected economic impact and employment. The exemption period can extend over several years depending on the project’s type and scale. It applies both to generation projects (wind farms, solar plants, biodigesters) and to investments in technology and related services. For more on available incentives, see our guide to tax benefits for investment in Uruguay.

Free Zones: Full Exemption from National Taxes

Companies located in Uruguayan free zones are exempt from IRAE, VAT, Wealth Tax and other national taxes on activities carried out in the zone. The regime is especially attractive for equipment manufacturing, component logistics, storage and distribution of renewable energy technology, and engineering or technology development services for clients abroad. A free zone company follows the general regime (SA, SRL or SAS) but requires authorisation as a user and compliance with investment, substance and local employment requirements.

Self-Generation and Distributed Generation

Companies can generate electricity for their own consumption by installing solar panels or wind turbines connected to their installations. This is very common in industry, agribusiness and logistics centres. In addition, the microgeneration and distributed generation rules allow surplus electricity to be fed into the UTE grid in exchange for compensation, which improves project returns. These schemes do not imply automatic tax exemptions, but they reduce operating costs, and the related investments may qualify for Investment Law benefits.

Practical Steps to Set Up the Company and Start Operating

Once the corporate structure is chosen and the applicable tax benefits assessed, incorporation follows an orderly sequence of procedures with the relevant bodies.

Incorporation and Mandatory Registrations

The process begins with drafting the articles, which define the corporate purpose, capital, management bodies, partners’ rights and decision-making mechanisms. For an SA or SRL, the articles are formalised before a notary and registered with the DGR’s Legal Entities Registry (the SA also goes through AIN review). For an SAS, the process is simpler and can be done online. Once registered, the company must be registered with DGI to obtain the RUT, declare its activity and tax regime (IRAE, VAT, etc.) and record its partners and managers. If the company will have employees, it must also register with BPS. The total timeframe ranges from about a day for an SAS through “Empresa en el Día” to several weeks for an SA.

Sector-Specific Permits and Authorisations

Depending on the activity, specific permits may be needed from the MIEM, the DNE, UTE (the state electricity company) or the sector regulator (URSEA). For example, grid-connected generation projects require UTE connection approval, environmental authorisations from the Ministry of Environment and compliance with technical connection rules. Self-generation projects must notify the installation and meet technical requirements. Professional services, software or consulting do not require sector permits, apart from municipal authorisation for the premises. It is advisable to consult a specialised adviser to identify all permits for the specific project before starting operations.

Business Bank Account and Beneficial Ownership Registration

To operate formally, the company must open a business bank account in Uruguay. Banks will require incorporation documents, identification of partners and managers, the beneficial ownership declaration filed with the Central Bank of Uruguay (BCU) and compliance with anti-money laundering policies. If there are non-resident foreign partners, the bank may request additional (apostilled or legalised) documents and a declaration of the source of funds. The process can take 2 to 4 weeks depending on the bank and the project’s complexity. See our guide to opening a business bank account in Uruguay.

Taxation of Renewable Energy Companies in Uruguay

The Uruguayan tax system is based on the territoriality principle: Uruguayan-source income is taxed in Uruguay regardless of the owner’s nationality or residence. This principle is key for foreign investors and international financing structures.

The main tax obligations are:

• IRAE (corporate income tax): general rate of 25% on Uruguayan-source net profits. Promoted projects can obtain partial exemptions for several years. Free zone companies do not pay IRAE on their free zone activities.
• VAT: basic rate 22% and reduced rate 10% for certain goods and services. Sales of electricity are taxed; qualifying exports of services or goods are relieved of VAT with the right to recover input VAT. Promoted projects may obtain a refund of VAT on investments.
• Wealth Tax (Impuesto al Patrimonio): taxes the company’s net assets at a flat 1.5% rate. Promoted projects (on their investments), free zone companies and certain exempt activities do not pay it. See more on corporate wealth tax in Uruguay.
• ICOSA (corporate control tax): paid only by SAs, as a fixed annual amount. SASs, SRLs and sole proprietorships do not pay it.
• BPS employer contributions: mandatory for each employee on the payroll.
