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

There are many benefits of using a trust, including asset protection and management, generational planning and for income tax and estate tax purposes. However, the US tax treatment of trusts can be complex, so our dedicated US Trust division offers up-to-the-minute advice and ensures you avoid the substantial compliance issues that affect US taxes on foreign income.

US taxpayers often participate in foreign pension plans as these can be useful, tax preferred, investment tools in the jurisdiction where they are a tax resident, but are treated differently in other jurisdictions. Complexities also arise when reporting to the IRS, given the substantial penalties for non-compliance. But we can help you, whether you are a US individual or a pension provider. Find Out More

Funds & Partnerships
US-Connected Tax Services
Investment Funds with US investors and/or US investments have extensive US reporting requirements. To navigate the extremely complex US tax system, our dedicated team of highly experienced, fund-focused US tax professionals offer customized services for every stage of a fund’s lifecycle. This includes structuring, advice on including US investors, US tax compliance and support for a clean exit. We specialise in K-1, K-2 and K-3 reporting for investors, CFCs (Controlled Foreign Corporation), along with PFIC (Passive Foreign Investment Corporation) testing. 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
Entities that are either a US-based or foreign partnership are required to designate a Partnership Representative to serve as the direct contact with the IRS for all taxable years. We are well placed to be a trusted and knowledgeable Partnership Representative to limited partners, general partners and limited liability companies. Find Out More
Corporations, US Expansion & FATCA
Corporations have different tax treatment from other business entities such as Partnerships. As an integrated firm of cross-border tax lawyers and accountants, we work with many types of corporate entities where there are US connections and are an attractive alternative to the Big Four in terms of fees, experience and proven history of working in multiple jurisdictions. We support corporations in an advisory capacity and through our suite of US compliance services. Find Out More
The US remains a focal market for companies looking to expand and scale their business, particularly with US-based investment, but the regulations and set-up can be daunting.

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
