Case studies
Foreign-owned LLC
“A Spanish-owned LLC in Florida had missed Form 5472 filings and risked $50K in penalties. We corrected the backlog and now provide ongoing compliance under our $850/month package – keeping them penalty-free and stress-free.”
E-commerce seller
“A Shopify seller in Latin America thought sales tax was covered because Shopify was withholding it. In reality, they were behind on filings and payments in multiple states. We registered them properly, filed past-due returns, and now manage compliance and reporting under our $1,750 CFO Partner package.”
U.S. person with global structures
“A U.S. expat in Portugal had multiple filings (5471, FBAR, 8938) and felt overwhelmed. We streamlined everything into our CFO Partner package, ensuring full compliance and ongoing tax strategy support.”
