International Tax
We help clients minimize tax, whether they’re U.S. citizens with interests overseas, non-resident aliens with business operations in the United States, or high net worth non-residents with investments in U.S. real estate.
With clients in more than four dozen countries, our expertise in international tax issues is unmatched.
From an outbound perspective, we advise U.S. businesses on structuring their foreign operations with the goal of minimizing U.S. taxation and complying with other U.S. accounting provisions. Through our Praxity alliance, we provide specialist support worldwide and work alongside colleagues in other highly rated firms to advise and assist clients with foreign tax and accounting matters and offer truly global solutions.
From an inbound perspective, we assist foreigners operating a business within the United States. We also advise foreign buyers of U.S. real estate on how to structure their purchases in a tax-efficient manner.
From a financial institution perspective, our international tax experts help both foreign and domestic financial organizations comply with the Foreign Account Tax Compliance Act (FATCA). Further, our bank compliance team assists foreign and domestic financial institutions with the implementation of anti-money laundering compliance programs.
