Tax

Based in Ecuador, Bustamante Fabara is the product of the merging of two leading firms, Fabara y Cia and Bustamante & Bustamante. With Fabara y Cia’s outstanding track record in Tax Controversy and Bustamante’s expertise in tax planning and business structuring, the newly formed firm aims to provide services for all tax matters. The firm has a 95% success rate in tax refund proceedings, and specializes in foreign trade, M&A transactions, dispute resolutions, and tax planning.

Over the research period, the firm has been active throughout the region. The firm represented Abbott Laboratorios del Ecuador in a customs dispute involving imports of pharmaceuticals classified as food for tariff purposes. The customs error was recognized as a violation of rights and the judgment serves as a guide for future resolutions in similar cases.
