However, international filers should use extra caution to avoid common mistakes that occur when taxpayers fill out these forms. These mistakes can lead to transmission failures, rejected tax returns or issues in creating or accessing an account. Here are some of the common mistakes international filers make while using these forms. Special characters, hyphens and spaces When creating an account or entering information on a form, taxpayers shouldn’t use any hyphenates or special characters such as ñ, ü, ó, and they shouldn’t leave spaces in first or last names. International addresses Many forms require taxpayers to use a U.S. mailing address. Entering an international address, including military addresses, APO, DPO and FPO, may cause the return to be rejected. Unfortunately, there isn’t a universal solution for this issue. International phone numbers Taxpayers should use a U.S. phone number when creating an account. Filers that use international phone numbers may not be able to create, access or recover their account. Certain forms only accept a 10-digit number, and international filers shouldn't use these forms if they don't have access to a U.S. phone number. Banks outside of the U.S. Direct deposit is available only for bank accounts located only in the United States. IRS Direct Pay requires a U.S. bank routing number. If the international filer has an account with an international bank that has a U.S. affiliate, the bank may be able to provide a U.S. bank routing number. Unsupported or prohibited forms for e-filing All taxpayers should familiarize themselves with the forms they need before starting a return. This will help them understand the information about a form and its limitations, which could prevent the taxpayer from filing electronically.
