If you’re a U.S. citizen or resident living or working abroad, you may still be required to file U.S. Tax returns and report your worldwide income. Managing tax obligations across multiple countries can become complex, especially when foreign accounts, treaty rules and state residency issues are involved.
Expats, dual residents, green card holders, and globally mobile individuals may need to navigate foreign account reporting, treaty rules, and state residency issues all at once.

Coordinated cross-border individual tax guidance. International tax for individuals often involves more than an annual tax return. RKL helps expats, dual residents, and globally mobile individuals address worldwide income reporting, foreign tax credits, foreign asset disclosures, and treaty considerations within a single coordinated cross-border strategy.
Practical support for complex foreign reporting. FBAR filing requirements, Form 8938 (Foreign Financial Assets), foreign entity reporting, and foreign pension issues can quickly become overwhelming. Our International Tax Team helps you understand what applies, what needs to be filed, and how to document positions clearly and accurately.
Structured remediation for missed prior-year filings. Many international reporting issues are often discovered after a taxpayer has spent several years abroad. RKL helps you evaluate streamlined filing compliance procedures and other remediation options, with a focus on risk assessment, documentation, and restoring compliance under current law.

Yes, in many cases. U.S. citizens and certain residents are generally required to report worldwide income to the IRS even if they live abroad and pay tax in another country.
An FBAR is generally required if the aggregate value of foreign financial accounts exceeds $10,000 at any time during the year. The rules can apply to accounts you own directly and, in some cases, accounts over which you have signature authority.
No. Form 8938 (Foreign Financial Assets) and the FBAR are separate reporting requirements with different thresholds, filing methods, and asset definitions. Some taxpayers may need to file both.
The foreign tax credit (Form 1116) may help reduce double taxation by allowing a credit for certain foreign taxes paid on income that is also subject to U.S. tax.
It depends on your facts and circumstances. In some cases, one approach produces a better result than the other, and in others, a combination may be appropriate. Modeling is important before making that decision.
A Passive Foreign Investment Company, or PFIC, is generally a non-U.S. corporation that meets certain income or asset tests. Many foreign mutual funds, ETFs, and pooled investment vehicles may fall into this category for U.S. tax purposes. PFIC rules can result in complex reporting obligations and unfavorable tax treatment if not addressed properly. U.S. taxpayers with PFIC investments may need to file Form 8621 (Passive Foreign Investment Company) and evaluate available tax elections based on the facts and documentation available.
Often, yes. Foreign pensions and retirement plans can raise both income tax and information reporting issues. Treatment varies depending on the country, plan structure and any applicable treaty provisions.
Missed filings can expose you to significant penalties, but there may be compliance options available. Depending on the facts, streamlined filing compliance procedures or other remedial measures may help you return to compliance.
Yes. Some states apply aggressive residency rules based on domicile, property, family ties, or other connections, even if you no longer live in the U.S. full-time.
Generally, yes, unless the U.S. has a Totalization Agreement with your host country. These agreements prevent you from paying into both social security systems. If an agreement exists, you can obtain a Certificate of Coverage that exempts you from U.S. self-employment/Social Security taxes while paying into the local system
