A Boutique Approach to Tax‑Driven Legal Strategy
OPENTAX was born from more than two decades advising international clients in Marbella’s real‑estate market, where legal certainty and tax efficiency define successful investments.
We reverse the traditional model: tax strategy first, legal execution second. A boutique approach that delivers clarity, protection, and long‑term value for foreign investors.
Who We Are
OPENTAX is a tax‑focused legal boutique guiding foreign investors through Spanish property acquisitions with precision, certainty, and strategic planning.
After more than twenty years working at the heart of Marbella’s real‑estate market, we understood a fundamental truth: legal security is essential, but tax planning is what truly shapes the success and long‑term profitability of an investment.
While most law firms involve the tax adviser only after the deal is closed, we place tax strategy at the beginning—designing the optimal structure, and then executing it legally with the same rigor.
We work openly and collaboratively with lawyers, agents, and international partners, offering our fiscal expertise as an added value to the entire transaction.
Beyond property acquisitions, we support individuals and companies with ongoing tax compliance, accounting, and business structures in Spain.
OPENTAX is built to deliver one thing above all: intelligent, efficient, and secure cross‑border investment.

How Important is Tax Planning?
Tax planning should be considered before buying property in Spain, not afterwards. A well-structured acquisition can reduce future tax liabilities, avoid costly mistakes, and ensure that your investment is both tax-efficient and fully compliant with Spanish regulations.
