To access a W-2 form as a USPS employee, one would typically need to visit the official USPS Human Resources Shared Services website. There, employees can log into their accounts using their credentials. Once logged in, the W-2 forms are often available for download in the employee self-service portal. It is important for employees to ensure that their personal information is accurate and that they have registered for online access to view their tax documents. In some cases, if the online access is not an option, USPS may also mail physical copies of W-2 forms to employees at their home addresses. For detailed information or specific inquiries, it can be helpful to check the current web page related to HR services for guidance on the process and contact information.
