EU market access, euro-denominated operations, and the banking window that opened when Turkey came off the FATF grey list in June 2024. Three things now align that were not simultaneously true in 2022.
Turkey occupies a specific position in European commercial geography: close, economically integrated through the EU Customs Union, and yet formally outside the single market. That distinction is not academic. It determines what a Turkish-registered company can and cannot do when it turns to face Europe.
For a Turkish entrepreneur with European clients, European suppliers or European ambitions, that right-hand column has always needed a solution. A Spanish SL is increasingly that solution — and the reasons now go well beyond market access.
The Turkish lira has lost the majority of its value over the past decade, reaching a record low of around ₺41.8 per US dollar in late 2024 and continuing a long depreciation trend that has steadily eroded the purchasing power and balance sheet value of lira-denominated assets. Periods of political and market volatility — including the events of March 2025, which triggered capital outflows and central bank intervention — have reinforced the case for holding assets and operating revenues outside Turkey.
A Spanish SL provides something the domestic system structurally cannot: euro-denominated operations, EU-regulated banking and an anchor outside the lira's volatility. This is not a judgment about Turkey. It is ordinary treasury and structural risk management, of the kind any exporter running two currencies would recognise.
This is the fact most Turkish entrepreneurs — and a good number of advisers — have not fully processed.
Documentation requirements remain rigorous, but the baseline risk classification has shifted. For founders who attempted Spanish banking in 2022 or 2023 and hit walls, the environment is materially different now — and the difference is structural, not a matter of finding a friendlier branch.
Turkey's relationship with the EU through the Customs Union creates a specific commercial logic for a Spanish subsidiary. The division is clean and immediately legible to Spanish tax authorities, banks and European clients.
Spain's bilateral relationship reinforces the logic. Trade between the two countries reached $19.2 billion in 2024, against a stated $25 billion target. Catalonia — home to Turkish companies including the logistics group Ekol and automotive supplier Orhan — maintains a dedicated trade office in Istanbul. The commercial infrastructure for Turkish business in Spain exists and is growing.
For Turkish IT companies, professional services firms, digital businesses and trading companies, Spain offers a credible EU anchor that is proportionately accessible: lower setup costs, a reduced corporate rate for qualifying new companies, and a simpler compliance environment than Germany or the Netherlands.
Until 3 April 2025, Turkish investors could obtain Spanish residency through the Golden Visa by investing at least €500,000 in Spanish real estate. Spain closed the programme on housing affordability grounds. For anyone who was treating it as the residency plan, this requires a rethink — and the remaining routes are more operationally relevant anyway.
With Turkey off the grey list the compliance baseline has improved, but Turkish-owned companies still need careful preparation for one specific reason: source of funds documentation from Turkish financial institutions.
The Turkish banking system operates in lira, with currency conversion and capital movement controls that have tightened during periods of central bank intervention. For a founder capitalising a Spanish SL, the question a Spanish compliance team asks is simple: where did this money come from, and how did it move from Turkey to Spain? The documentary answer needs:
This is not a political judgment about Turkey. It is a standard source-of-funds requirement that the recent macro environment simply makes more work to satisfy.
A Spanish SL owned by a Turkish founder, with Turkish clients and Turkish-sourced revenue, has to explain what the Spanish entity actually does. "To hold euro assets and invoice European clients" is a legitimate and perfectly explainable answer — provided it is documented rather than assumed. The applications that fail are the ones where nobody wrote it down.
Spain and Turkey have a Double Taxation Agreement signed in 2002 and effective from 2004. It allocates taxing rights between the two states, sets residency rules, determines where business profits are taxable, and caps withholding on dividends, interest and royalties flowing between the jurisdictions. The applicable caps depend on the type of income and, for dividends, on the size of the shareholding — which is why the shareholding structure should be settled before the first distribution rather than after.
Transfer pricing becomes operationally relevant from day one. Both Spain and Turkey apply transfer pricing rules to related-party transactions, requiring intercompany prices — for services, goods, IP licensing and management fees — to reflect arm's length market rates. The Agencia Tributaria has intensified enforcement in this area in recent years, and a parent-subsidiary pair with cross-border invoicing is precisely the profile that attracts review.
Understanding the treaty framework before incorporation, rather than after the first intercompany invoice has been issued, prevents the class of retrospective compliance problem that is substantially more expensive to unwind than to design around.
Three conditions now hold at the same time, which was not the case three or four years ago.
For Turkish founders deciding where to anchor European operations, the combination of accessible incorporation, improved banking conditions and genuine bilateral commercial momentum makes Spain the most actionable option in Southern Europe right now.
