Lullius has been recognised for the first time in ITR World Tax, one of the leading international directories dedicated to tax advisory services. In its debut appearance in the 2027 edition, the firm has secured two rankings in Spain, entering directly at Tier 2 in Tax Controversy and Tier 3 in Transactional Tax.

Xavier Rubert, Managing Partner of Lullius, has also been individually recognised as “Highly Regarded” for Tax Controversy in the 2027 edition of ITR World Tax.

The recognition marks an important milestone for Lullius and spans two core areas of its practice: representing clients in complex tax disputes and advising on the tax implications of transactions.

Based in Palma de Mallorca, Lullius advises Spanish and international clients on matters where tax, private wealth and business interests intersect. Its approach combines technical analysis, commercial judgement and close partner involvement, from the initial structuring of a transaction through to the resolution of a dispute.

“To enter ITR World Tax for the first time with rankings in both Tax Controversy and Transactional Tax is an important milestone for Lullius,” said Xavier Rubert, Managing Partner. “It recognises the work of our team across two closely connected disciplines and the trust our clients place in us. We have built the firm around a clear conviction: sound tax advice requires both the foresight to structure a transaction and the expertise to defend it.”

ITR World Tax assesses tax advisory firms and practitioners across jurisdictions worldwide. Its annual research draws on an evaluation of their work, professional experience and feedback from clients and peers. The assessment considers, among other factors, the complexity of matters handled and the solutions delivered to clients.

For Lullius, these rankings reinforce its commitment to providing clear, rigorous advice on complex Spanish and cross-border tax matters, with a particular focus on the needs of businesses, private clients and family offices.
