Castell.tax, the tax practice of Castell.law
Castell.tax is the tax practice of Castell.law (Castell Law & Investments), a Balearic law firm with more than twenty years advising international clients. We combine tax advisers and lawyers, so the same team that files your returns can also plan an inheritance, structure a company or defend you before the tax agency.
Tax, connected with everything else
Most of our clients come to us for a specific return: the modelo 210 for a holiday home, a first Spanish income tax return or the sale of a property. Many then stay with us for their yearly taxes, an inheritance, a company or a move to Spain. A firm that knows your whole situation can plan instead of just filing.
Castell.tax is part of Castell.law, the international side of the Castell group of law firms, which also includes Castell Abogados. We work in English, German and Spanish.
Our people
- Carlos Castell — CEO, lawyer, investments and project management.

We also work with many other collaborating lawyers, accountants, tax advisers and lawyers in Spain and abroad, so each matter has the right specialist.
