GoSystem Tax RS

GoSystem Tax RS is Thomson Reuters’ enterprise-level tax preparation platform for large accounting firms and multi-office practices. It is a web-based application that handles high volumes of complex corporate, partnership, individual, and fiduciary returns with centralized administration.

Firms use GoSystem Tax RS when they need centralized control over user access, templates, and return configurations across multiple offices. The web-based architecture means preparers access the software through a browser without local installations, which simplifies IT management in large firms. It integrates with Thomson Reuters’ research tools (Checkpoint), document management, and workflow systems.

GoSystem Tax RS is best suited for large US firms and national practices — it is commonly used by Top 100 and Big Four firms that require enterprise-scale processing, role-based security, and centralized oversight. Smaller firms typically find UltraTax CS or ATX more appropriate for their needs.
