More U.S. startups and venture funds are looking at Spain as their first foothold in Europe. The reasons are practical, not sentimental: a large domestic market, a growing tech talent pool in Madrid and Barcelona, and a government that has spent the last few years actively courting founders with tax incentives built specifically for startups. Spain is also, increasingly, the base American companies use to reach the rest of the European Union and, through language and business ties, Latin America.
None of that makes incorporation automatic. Spain has its own entity types, its own tax rules, and its own immigration system, none of which map cleanly onto what a Delaware-incorporated founder is used to. This guide walks through what a U.S. company or investor actually needs to know before setting up in Spain.
Why Spain Keeps Coming Up in Expansion Conversations
Three things make Spain a recurring answer when U.S. founders ask where to land first in Europe. The first is market access: entering through Spain gives a company a foothold in the EU’s single market, with harmonized rules on data, competition, and e-commerce across all member states. The second is cost and talent: engineering and operations talent in Spain is competitive on both quality and cost compared to Northern Europe or the U.S. The third is Spain’s own effort to attract startups directly, through a dedicated legal framework (more on that below) that most European countries don’t have.
Choosing the Right Legal Structure
The Sociedad Limitada (SL): Spain’s version of an LLC
The most common entity for a U.S. company setting up in Spain is the Sociedad Limitada (SL), roughly Spain’s equivalent of a private limited liability company. It can be formed with a single shareholder, requires as little as one euro in share capital following recent reforms, and can be incorporated electronically in a matter of days through Spain’s CIRCE system, without the multiple in-person notary visits that used to slow the process down.
For a U.S. parent company, the SL typically operates as a subsidiary: a separate legal entity, locally incorporated, that can hire employees, sign contracts, invoice in euros with Spanish VAT, and open a local bank account. A branch (sucursal) is also possible, and functions as an extension of the U.S. parent rather than a separate legal person, but most U.S. companies prefer the subsidiary route because it limits liability exposure back to the parent.
Keeping Delaware in the picture
Most U.S. investors expect the cap table to sit on top of a Delaware C-Corp, and that expectation doesn’t have to change just because operations move to Spain. The common structure is a Delaware parent holding a Spanish SL as its operating subsidiary, which lets the company raise from U.S. VCs under familiar terms while running commercial operations, hiring, and local contracts through the Spanish entity. Getting the order of incorporation and the intercompany agreements right from day one avoids a costly restructuring later, particularly once the company has already closed a priced round.
Spain’s Startup Act: Tax Incentives Worth Knowing
In 2022, Spain passed a dedicated law to support high-growth, innovative companies, generally referred to as the Startup Act. Companies that qualify and get certified as an “empresa emergente” by ENISA, the public agency that evaluates innovative and scalable business models, can access a reduced 15% corporate tax rate (versus the standard 25%) for up to four years of positive taxable income, along with deferred tax payments and relief from advance tax installments during the early years.
The law also improved the tax treatment of employee stock options, a detail that matters directly to U.S. investors used to equity compensation as a core hiring tool: the first 50,000 euros a year in stock option gains are now tax exempt for employees, with the remainder eligible for deferral. This narrows, though doesn’t eliminate, the gap between how equity compensation is taxed in Spain versus the U.S.
The Visa Question: Why Spain Isn’t an E-2 Country
Here’s a detail that surprises a lot of American founders: Spain does not participate in the U.S. E-2 treaty investor visa program, unlike several other European countries. That visa category only works for citizens of countries that hold a qualifying commerce or investment treaty with the United States, and Spain currently isn’t on that list. In practice, that means a U.S. investor can’t use the E-2 route to move to Spain to run a business there.
What Spain offers instead is its own residency framework, built independently of any treaty with the U.S. The Entrepreneur Visa, created under Spain’s 2013 Entrepreneurs Law, is designed for founders launching an innovative business of particular economic interest to Spain, and doesn’t require reciprocity with the applicant’s home country. Spain also extended its special tax regime for inbound workers, informally known as the Beckham Law, to entrepreneurs, remote workers, and international teleworkers moving to Spain, allowing qualifying individuals to pay a flat personal income tax rate for their first years of residency rather than the standard progressive scale. For a U.S. founder relocating a founding team, this combination, entrepreneur visa plus the flat-rate tax regime, is generally the practical path, not the E-2.
Foreign Investment Screening: What to Clear First
Spain, like most EU countries, screens inbound foreign direct investment from outside the EU and EFTA in certain strategic sectors, including critical infrastructure, technology, dual-use goods, and media, above defined investment thresholds. Most early-stage venture investment in a Spanish startup falls well outside the scope of this screening regime, but it becomes directly relevant for larger growth-stage rounds, acquisitions, or any deal touching a sector the regime treats as sensitive. Checking whether a transaction requires prior government authorization should be one of the first questions asked when structuring a significant investment, not something raised at closing.
The U.S.-Spain Tax Treaty: Avoiding Double Taxation
The United States and Spain are bound by a bilateral tax treaty, most recently updated through a protocol that entered into force in 2019 and meaningfully lowered withholding tax rates on cross-border payments between the two countries. Under the current treaty, dividends paid between qualifying parent and subsidiary companies can, in many cases, flow with a 0% withholding rate, with reduced rates applying to smaller shareholdings, and interest and royalty payments between the two jurisdictions are also generally eligible for a 0% rate under the treaty’s provisions. This treaty is the tool that keeps a Delaware parent and a Spanish subsidiary from having the same income taxed twice, but it only works cleanly when the corporate structure and intercompany flows are designed with the treaty’s requirements in mind from the outset.
Common Mistakes U.S. Companies Make
The most frequent mistake is treating the Spanish subsidiary as a copy-paste of the Delaware entity, down to employment contracts and equity documentation that don’t reflect Spanish labor law or local tax treatment. A close second is assuming an American founder can simply move to Spain the way they’d move to a country with an E-2 treaty, only to discover mid-relocation that the visa strategy needs to be entirely different. A third is closing a significant investment round without checking whether the transaction triggers Spain’s foreign investment screening requirements, which can delay or complicate closing if raised too late.
How Delvy Helps
At Delvy, we help U.S. founders, investors, and tech companies set up and structure their presence in Spain the right way from the start: choosing between a subsidiary and a branch, structuring the Delaware-to-Spain holding relationship, securing Startup Act certification, applying the U.S.-Spain tax treaty correctly, and navigating the entrepreneur visa and Beckham Law regime for relocating team members. Our position between both markets means we speak both the U.S. investor’s language and Spain’s regulatory reality.
