GoSystem Tax RS review
A cloud platform for firms managing complex, high-volume corporate filings.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
GoSystem Tax RS is cloud-based professional tax preparation software from Thomson Reuters for accounting firms handling complex U.S. tax work. Its coverage includes corporate, consolidated, partnership, fiduciary, individual, multistate, state, and local returns. Firms working with multitiered structures and high-volume filings get electronic filing, prior-year access, simultaneous collaboration, batch processing, paperless workflows, trial balance tools, and diagnostics in a web-based platform.
Pricing follows a contact-sales model rather than published plan tiers. The platform is available through the web and REST APIs, with connections to FirmFlow, time-and-billing systems, Thomson Reuters products, and third-party applications. Those integrations support firms that need to move return data across tax, practice-management, and other business systems. The APIs cover importing, exporting, and e-filing return data, giving larger practices an option for more structured workflows.
The standout fit is its handling of consolidated and multistate work. Data imports from tax documents, trial balances, and workpapers can reduce manual entry, while built-in trial balance and diagnostics support review before filing. Multiple users can access the same return simultaneously, which suits collaborative tax teams. GoSystem Tax RS makes the most sense for firms managing complex corporate structures, recurring multistate filings, and substantial return volume. Smaller practices seeking a narrowly focused corporate tax tool, transparent tiered pricing, or a simpler workflow may find its wider return coverage and enterprise-oriented features more than they need.
