It may come as a shock to foreign (non-US) companies and other foreign businesses to learn that they may have US tax withholding obligations with respect to their US employees, even if the foreign business is not in any way involved in US activity. Pursuant to the US Internal Revenue Code, an employer is required to withhold federal income and social security taxes from the wages of its US employees. Every quarter, the employer must file a Form 941, the Employer’s Quarterly Tax Return, reporting the amount of income and social security tax withheld during the period. A Federal Tax Deposit Form must be filed with the remittance of the withholding taxes the month following the close of each quarter.
