International Tax
Whether you’re a US citizen or resident with foreign source income or a non-resident who plans to work in the U.S., we often provide consulting  and tax preparation for inbound and outbound expatriates.

Foreign Investment Companies & Inbound – For foreign companies who have direct investment to the U.S., our tax related services include payroll, gross-up and exchange rate conversion, tax planning, and tax preparation services. Employees, such as inbound expatriates, often have FBAR/FATCA requirements (for foreign accounts and/or assets), ITIN application, visa/green card, dual status, and including a foreign tax return. Double taxation can be avoided using tax treaties, while totalization agreements can avoid duplication of social security taxes.

U.S. Expatriate & Outbound – If you are a U.S. citizen or resident alien, the rules for filing income, estate, and gift tax returns and paying estimated tax are generally the same whether you live in the United States or abroad. The Federal tax code requires all taxable income to be reported and tax on worldwide income from all sources.  However, double taxation can be avoided by qualifying for tax treaty benefits, such as the Foreign Earned Income Exclusion and Foreign Tax Credit. FBAR/FATCA may be required for holding more than $10,000 in combined foreign accounts.
