Who can open a unipersonal in Uruguay? Labor, capital, and examples by profession

“Can I open a unipersonal?” is one of the first questions for anyone starting to work on their own in Uruguay. The short answer is: almost certainly yes. The more interesting question — and the one that really matters — is how your activity will be taxed. And that depends on a couple of simple ideas: labor and capital. In this post we explain who can open a unipersonal and how those two factors decide your taxes, with examples for different professions.

What a unipersonal is

A unipersonal business is not a company: it's you, an individual, carrying out an economic activity on your own account. There's no separation between you and “the business” — you use your own name and you're liable with your personal assets. To exist, you register as a taxpayer with the DGI (where you get your RUT to invoice) and with the BPS.

This is how the State defines the unipersonal procedure: an individual registering as a taxpayer before starting their activity.

«Es el trámite mediante el cual una persona física cumple con la obligación de inscribirse como contribuyente ante la Administración Tributaria previo al inicio de la actividad económica.»

In English: It is the procedure through which an individual fulfills the obligation to register as a taxpayer with the Tax Administration prior to beginning economic activity.

Who can open a unipersonal?

In practice, almost any individual of legal age with an ID (cédula de identidad or passport) can register a unipersonal — whether you're Uruguayan or a newly arrived foreigner. You don't need partners, a minimum capital, or a degree. What defines everything is that you'll carry out an economic activity on your own account.

Some typical unipersonal profiles:

• Independent professionals: accountants, lawyers, architects, doctors.
• Digital workers: developers, designers, consultants, marketers.
• Trades: electricians, plumbers, hairdressers, photographers.
• Commerce: those who buy and sell goods, in a shop or online.
• Small-scale production: artisans and those who sell what they make.

The key: labor and capital

Here's the idea almost no one explains well. Every economic activity combines, to different degrees, two factors: capital (what you invest — machines, inventory, a premises, vehicles, money) and labor (your personal effort). Uruguayan law looks at which of the two predominates to decide how you pay. When there's a real combination of capital and labor, there's an “enterprise”, and that pays IRAE (the business income tax). The law itself says so:

The legal definition of “enterprise” is precisely the combination of the two factors: capital and labor.

«Se considera empresa toda unidad productiva que combina capital y trabajo para producir un resultado económico.»

In English: An enterprise is considered to be any productive unit that combines capital and labor to produce an economic result.

When labor rules: personal services

And what if all you bring is your work, with no relevant capital behind it? Then you're not an “enterprise” in the business-income sense: you provide a personal service. The law expressly excludes from business income the work of professionals and other trades when the predominant factor is labor. That income pays IRPF (the personal income tax), though it can opt to file IRAE if that suits it better:

And the law makes the other side clear: when labor is what predominates, that professional income falls outside business income.

«No se encuentran comprendidas en el inciso anterior las rentas derivadas de actividades desarrolladas en el ejercicio de su profesión por profesionales universitarios con título habilitante, rematadores, despachantes de aduana, corredores y productores de seguros (…), siempre que el factor productivo predominante lo constituya el trabajo.»

In English: The income derived from activities carried out in the exercise of their profession by university professionals with a qualifying degree, auctioneers, customs brokers, insurance brokers and agents (…) is not included in the preceding paragraph, provided that the predominant productive factor is labor.

Examples by profession

The best way to grasp it is with concrete cases. See which factor predominates in each activity and how it usually pays (this is a general guide — your case may have nuances):

Unipersonal, Monotributo and régimes

“Unipersonal” is the form (you're an individual with an activity); the régime is how you're taxed within it. Small selling activities in public spaces or tiny shops can usually use Monotributo. The rest falls under IRAE (which can be filed on an assumed or actual basis) or, if it's pure labor, under IRPF. We develop this in our posts on the legal forms and the taxes each form pays.

In short: opening a unipersonal is within reach of almost any individual. What truly defines your taxes is whether labor predominates in your activity (personal service → IRPF, with the IRAE option) or a combination of capital and labor (enterprise → IRAE), with Monotributo for the smallest. Want to know what applies to you, with numbers and deadlines? Tributo builds your calendar and shows where each figure comes from. And always verify with the DGI and BPS before deciding.
