Accounting & Tax Services in Miami, FL

Miami-Dade County’s $344.9 billion metro GDP makes it the largest urban economy in Florida and a magnet for international commerce. The Brickell financial district alone hosts over 100 international banks, while Doral’s warehouse corridors serve as the primary distribution hub for Latin American trade. With 58% of Miami residents born outside the United States, businesses here routinely handle multi-currency transactions, cross-border supplier payments, and foreign-sourced income reporting.

Florida’s 5.5% corporate income tax applies only to C-Corps earning above $50,000, making S-Corp and partnership structures particularly advantageous for Miami business owners. Import-export companies operating through PortMiami and Miami International Airport face additional complexity around customs valuation, transfer pricing, and international information returns like Form 5471 for controlled foreign corporations.

SDO CPA works with Miami business owners in international trade, fintech, healthcare, and professional services to structure entities for cross-border efficiency, optimize S-Corp reasonable compensation, and manage the interplay between federal tax obligations and Florida’s business-friendly environment. For businesses along the Wynwood tech corridor or the Coral Gables corporate district, we provide monthly bookkeeping and fractional CFO services scaled to your growth stage.

Florida Tax Planning Tip

Florida has no personal income tax, making it ideal for S-Corp and partnership owners whose business income passes through to their personal return. However, C-Corps pay Florida’s 5.5% corporate income tax on income above $50,000. For most Florida business owners earning $150K+, the S-Corp structure saves $8,000-$25,000 annually in self-employment taxes alone.

Miami is home to 42,000+ small businesses and a population of 449,514. From International Trade, Finance & Banking, Healthcare to professional services, Miami business owners need CPAs who understand international transaction complexity and multi-currency accounting for cross-border businesses and can provide year-round tax planning — not just compliance.
