U.S. Tax & Accounting for Internationally Connected Clients

Where U.S. Tax Law
Meets the Global Client

Miami-based CPA firm serving foreign investors with U.S. assets, American citizens with international holdings, and the businesses that operate between both worlds. Full-service tax, accounting, and cross-border advisory — all under one roof.

The CPA Firm for Clients Who Cross Borders

Miami sits at the crossroads of U.S. and international capital — and the clients here reflect that. Foreign nationals acquiring American real estate. U.S. entrepreneurs with offshore operations. Families splitting time between two countries. These clients need a CPA who understands both sides of the equation.

Biscayne Bay Advisory provides the full range of U.S. tax and accounting services — preparation, planning, bookkeeping, compliance — but every engagement is informed by our fluency in international tax. That means your bookkeeper understands foreign entity implications. Your tax preparer catches cross-border reporting obligations. And your advisor thinks globally by default.

U.S. Tax Expertise, Extended Across Borders

Our foundation is U.S. tax law. But when clients have international connections — foreign investments, overseas income, non-resident status, or plans to move to or from the United States — the domestic rules interact with international provisions in ways most advisors aren't equipped to navigate.

We map how U.S. tax obligations apply to your specific international situation, identify exposures across income tax, reporting, entity classification, and treaty positions, and build strategies that keep you compliant and protected on both sides of the border.
