ATX Professional is a desktop-based tax preparation application from Thomson Reuters designed for small to mid-sized US accounting firms. It handles individual (1040), business (1120, 1120S, 1065), estate (706), trust (1041), and nonprofit (990) returns with built-in diagnostic checks and e-filing.

Firms use ATX for its relatively straightforward interface and lower price point compared to Thomson Reuters’ other tax products (UltraTax CS and GoSystem Tax RS). It includes prior-year data import, automated calculations, and integration with Thomson Reuters research tools. Client management features help firms track return status and deadlines during tax season.

ATX is best suited for smaller US tax practices that need a reliable, cost-effective preparation tool. Firms that handle higher volumes or need multi-office capabilities typically look at UltraTax CS or GoSystem Tax RS.
