Many American citizens who have lived outside the United States for a number of years find it increasingly difficult to reconcile paying and reporting taxes on worldwide income to the US. For personal or financial reasons, an individual may decide to renounce their US citizenship. Under certain circumstances, the US may then impose an expatriate tax or “US Exit Tax” at the time of expatriation. Find Out More

Partnerships, both domestic and foreign, have distinct tax treatment compared to corporations. They submit annual information returns but do not pay income tax themselves. Instead, they distribute profits or losses to partners (individuals, corporations, trusts) using K-1 forms. Limited Partnerships, common in Private Equity and Venture Capital, fall under this category. Foreign partnerships with US operations typically file US partnership income returns, and non-US partners may need to file US non-resident income tax returns (individuals) or a US Income Tax Return of a Foreign Corporation (corporations). Non-US partnerships with US partners may face complex US reporting requirements even without US operations. Find Out More

The Foreign Account Tax Compliance Act (FATCA) is a US federal law that is intended to target US Persons who may be concealing assets held in foreign accounts. When the relevant financial institutions identify their US customers in accordance with FATCA, they must report them to the IRS. If a taxpayer’s US tax returns or information reports have not been filed, or incorrectly filed, the US taxpayer could be subject to civil penalties and possible criminal charges, and the bank may be fined. We can help you bring your filing up to date and compliant. Find Out More
