TeaPea is listed in the 2026 Financial & Tax Strategies ranking published by Décideurs Magazine, in the “High Profile” category for tax law, under the transfer pricing category.
The firm was founded in January 2026. This recognition therefore comes less than a year after it opened, in a ranking based in part on feedback gathered from clients.
Key Takeaways from Décideurs
The ranking is accompanied by an editorial analysis, which we reproduce in its entirety:
"Although it was just recently established, the firm can already boast of serving several major international corporations and is committed to providing the same level of advice to smaller companies. Client referrals help fuel its growth."
“‘The price of expertise’ could be Marion Aguilar’s motto as she launches her firm. She now brings her clients the benefit of a dual career path forged first at EY Société d’Avocats and then at CMA CGM. This dual background has been particularly formative, enabling her to offer rigorous, responsive advice that is always grounded in a deep understanding of the challenges facing businesses.”
A Confident Approach
These principles are in line with the philosophy that guided the firm’s founding: to offer mid-sized companies and growing corporations the same level of technical expertise enjoyed by the largest corporations, without resorting to standardized approaches.
Transfer pricing lies at the intersection of tax law, economic analysis, and corporate strategy. It requires specialized expertise, but also an understanding of the company’s operational constraints, because a transfer pricing policy is not implemented by the tax specialist who designed it: it is implemented on a day-to-day basis, over many years, by operational teams, the accounting department, and management control.
This recognition is owed first and foremost to the companies that placed their trust in a firm that had just opened its doors, as well as to our colleagues who thought of TeaPea whenever a transfer pricing issue arose.
