Employees of International Organizations
Working for Supranational Organizations such as the UN, EC, WHO or WB has many advantages - your tax status being one of them. However, this benefit significantly complicates your U.S. tax reporting. Due to the increased level of tax complexity we advise having your taxes handled by a qualified professional.
Many of our clients work for Supranational Organizations. Hence we are very familiar with the issues they face (such as proper exclusion of Social Security tax, reporting income from the Form 1099 as wages, calculation of the non-taxable portion of pension benefits, etc).
