## About

VivaldiTax is a boutique US international tax firm engineered for cross-border founders, expats, and e-commerce operators. We handle the technical compliance work most generalist CPAs avoid — Forms 5471 and 5472 for foreign-owned and US-owned entities, FBAR filings, transfer pricing documentation — and pair it with the strategic structuring work that actually moves the needle: entity selection across jurisdictions, US tax treaty optimization, IRS resolution support, and outsourced CFO services for businesses preparing for investor conversations.

Our founder, Michelle Vivaldi, is a CPA, JD, and US international tax specialist. Every client works directly with Michelle — no junior staff, no handoffs, no template responses. We serve clients fully bilingual in English and Spanish, with a particular focus on the Hispano-American expat market that is chronically under-served by traditional US firms.

What sets us apart: we treat tax as a forward-looking financial engineering discipline, not a backward-looking compliance chore. Our Investor Readiness engagements help founders prepare for capital events with clean books, defensible structures, and the kind of documentation that survives diligence. For operating businesses, we layer fractional CFO support to keep financial clarity ongoing.

Based in Miami. Serving founders and operators in the US, Latin America, Europe, and beyond.
