International Tax Advisors

What International Tax Advisors does

International Tax Advisors, B.V. is a private tax consulting firm headquartered in Belnem, Bonaire (Caribbean Netherlands), specializing in cross-border tax advisory for US individuals and companies with interests on Bonaire. Founded in 2016 as a sister entity to American Consulting Group, B.V. (est. 2009), the practice was operated as a sole-practitioner model led by attorney Bruce Zavon, who brought nearly 40 years of tax experience including a Touche Ross & Co. background and continuous Bonaire-specific work since 2009; associate Bernice Stephens provided native Dutch-language compliance support. The firm offered tax consulting, compliance, and return preparation services, addressing niche issues such as the US-Bonaire Double Tax Decree, the BES 0% corporate tax regime, and post-TCJA GILTI/Section 965 reporting for US persons owning Bonaire B.V./N.V. entities. The firm relied on a direct, sales-led consulting model with quote-based professional services pricing, targeting three geography-defined segments: US expats and remote workers, US investors and business owners, and US property owners on Bonaire. Client acquisition was driven by organic content marketing through the firm's informational website (zavontax.com), with no paid advertising, no proprietary technology platform, no app, and no disclosed integrations. As of January 2023, Bruce Zavon announced his exit from the tax preparation and consulting business, the firm stopped accepting new clients, and existing clients were transitioned to Stephens Tax & Administration (Bonaire) and BNCTax (Amsterdam); the website remains online for informational purposes only and is not being updated.
