Portugal vs Spain vs UAE: Choosing the Right Jurisdiction for Your First International Entity

The jurisdiction comparison is most useful before those decisions are made — when it can inform the structure rather than rationalise it. This article is written for that earlier stage: the point at which the options are genuinely open and the choice between Portugal, Spain, and the UAE is a real one.

The comparison is direct. All three jurisdictions have genuine advantages. All three have genuine limitations. The right answer depends on what the business actually needs — not on which jurisdiction has the most attractive headline rate.

The UAE occupies a specific position in international structuring: zero corporate tax on most activities until recently, straightforward company formation, world-class banking infrastructure, and a time zone that works well for businesses operating across Asia, Africa, and Europe simultaneously.

The 2023 introduction of a 9% federal corporate tax changed the calculus somewhat — but the UAE remains attractive for businesses with genuine operations in the Gulf, significant non-EU revenue, or a need for the kind of banking relationships and financial infrastructure that the UAE's major institutions provide.

The honest assessment: 

The UAE works for businesses whose primary operations and revenue are genuinely in the Gulf or internationally — and for founders who intend to be physically present there. It is a poor substitute for an EU entity for businesses whose actual market is Europe, because it does not provide the infrastructure, the regulatory credibility, or the banking access that EU incorporation does.

Spain is the first comparison most founders make when Portugal is suggested. Larger market, larger economy, more obvious international brand. Barcelona and Madrid have developed startup ecosystems, established professional services networks, and well-understood legal frameworks.

Spain is also, for most non-EU founders at the entry stage, more expensive and more complex to operate in than Portugal — in ways that matter when you are still testing whether the EU model works.

The honest assessment: 

Spain is the right choice when Spain is the target market — when the business intends to acquire Spanish customers, build Spanish operations, and grow in the Spanish market specifically. It is a less compelling choice as an EU entry point for businesses whose actual target is the broader EU, because the higher costs and acquisition economics compress what the entry budget can learn.
Portugal and Spain are not interchangeable. The choice between them should be driven by where the business intends to operate commercially, not by which country name sounds more impressive to an investor.

For non-EU founders using Portugal as an entry point into the EU rather than as a destination market, the relevant question is not whether Portugal is a large enough market. It is whether Portugal provides the legal and operational infrastructure needed to test the EU model, generate valid data, and build the structure for subsequent expansion.

The honest assessment: 

Portugal is the most efficient entry point into the EU for most non-EU founders — not because it is the largest or most prestigious market, but because the cost of testing, the legal infrastructure, and the tax environment combine in a way that no comparable EU jurisdiction currently matches. The Madeira MIBC regime adds a structuring option that is unavailable elsewhere in the EU at this tax rate.

For most internationally-oriented businesses at an early stage of EU operations, the 1–2 employee tier is the relevant starting point. The €2.73 million annual profit ceiling covers a significant range of qualifying income — and as the business grows, the ceiling scales with headcount.

There is also an EU State Aid cap that operates independently: the benefit is limited to the most restrictive of 20.1% of gross value added, 30.1% of labour costs, or 15.1% of turnover. For capital-light businesses with high margins and modest payrolls, this cap — not the profit ceiling — may be the operative constraint. This is a calculation worth running before the structure is built.

The table above is useful for eliminating options. It is less useful for making the final decision — because the final decision depends on specifics that a table cannot capture.

A business whose primary revenue comes from Gulf clients, whose founders intend to be based in Dubai, and whose EU exposure is limited to a few contracts does not need a Portuguese company. It needs a UAE structure, and possibly a European entity later when the EU exposure grows.

A business entering the EU to acquire European customers, build European operations, and scale across European markets needs an EU entity — and within that category, Portugal offers more per euro of entry cost than Spain, France, or Germany for a business that hasn't yet validated the model.

A business with significant qualifying income and the capacity to maintain genuine Madeira substance should be looking at the MIBC regime before the 2026 licensing deadline closes.

These are not mutually exclusive positions. Many well-structured international businesses have a UAE entity for Gulf operations, a Portuguese Lda. for EU operations, and a Madeira MIBC entity for income structuring. The question is not which jurisdiction to choose — it is which jurisdiction serves which function, and whether the structure is coherent as a whole.

Jurisdiction selection is not a ranking exercise. Portugal, Spain, and the UAE each serve specific purposes for specific business models. The mistake is choosing a jurisdiction for its headline tax rate, its brand recognition, or because a founder in a LinkedIn post recommended it — rather than because it fits the actual structure of the business.

The questions worth answering before the decision is made: Where are the customers? Where will the founders and key team be based? What is the primary currency and transaction flow? What does the banking relationship need to look like? And — the question most often skipped — what does the structure need to look like in three years, not just today?

Portugal is the right answer for a specific and well-defined set of situations. So is Spain. So is the UAE. Understanding which situation you are in is the work that precedes the jurisdiction decision.
