Established in 2017, the international tax firm is highly recommended for its expertise in tax advisory. The practice is separated into five areas: tax advisory, transfer pricing, commercial practice, private clients, and the oil, gas, and power unit. The tax team provides full tax and legal support on both contentious and non-contentious matters. The firm is part of one of the most extensive tax networks spanning across 146 locations within 18 countries and has two Nigerian offices in Lagos and Abuja. The tax team is led by managing partner Olaleye Adebiyi, who is supported by six tax partners and three directors.
