Aster & Trujillo

Cross‑Border Tax, Corporate and Advisory

Luis E. Trujillo Garzón is the founding director and managing partner of Aster & Trujillo, where he leads the firm's cross‑border tax, corporate and advisory practice from London.

Luis advises Spanish, European and Latin American groups on all aspects of establishing and consolidating substantial business operations in the UK, combining technical tax and corporate expertise with a commercially driven, hands‑on approach. His work encompasses the design and implementation of cross‑border holding and trading structures, treaty‑based planning, residence and domicile analysis, capital gains and inheritance tax coordination under double tax treaties, and the application of special regimes such as Spain's "Beckham Law". He regularly handles UK corporation tax, VAT (including postponed accounting, import VAT and deferment accounts), PAYE, CIS compliance and group relief, integrating these with Spanish and Latin American tax obligations to ensure coherent, defensible positions across jurisdictions.

Beyond tax, Luis acts as the de facto CFO and company secretary for a number of Spanish corporate clients operating in the UK, overseeing financial reporting, management accounts, statutory filings, cash‑flow management and board‑level governance. He takes direct responsibility for corporate banking relationships, Companies House compliance and the strategic financial planning of UK subsidiaries within international groups.

Luis has strong working knowledge of the UK immigration framework and routinely supports clients on sponsor licence applications, Skilled Worker visas and Global Business Mobility routes, ensuring that workforce planning, visa strategies and employment contracts are aligned with the group's tax, social security and commercial objectives. He drafts and reviews UK‑law employment contracts for local hires and international secondees, and coordinates A1 certificates, social security positioning and residence analysis for mobile employees.

His practice also covers the legal and commercial framework around major contracts: he prepares and negotiates UK commercial agreements, subcontracting arrangements and supply‑chain documentation, ensuring that risk allocation, intellectual property and jurisdictional provisions are consistent with the client's wider tax and corporate structure.

Luis is responsible for the firm's legal and compliance function, including AML, KYC and anti‑bribery frameworks, and leads a bilingual team of accountants, tax advisers and lawyers operating across London and Spain. He works daily in English and Spanish, liaising directly with clients' advisers across Spain and Latin America, and many of his mandates are long‑standing relationships of seven years or more, during which he has accompanied groups through expansion, reorganisation and new market entry across the UK, Spain and Latin America.
