Planner CS review
A planning workspace for federal, state, multi-year, and scenario-based tax analysis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Planner CS is tax planning software from Thomson Reuters for accountants and tax professionals. It supports federal and state tax projections, multi-year planning, resident and nonresident state analysis, withholding calculations, and comparisons of filing alternatives. The product also tracks carry-forward items, calculates payments, and produces client-ready reports, graphs, and letters. Its positioning fits professionals who need structured planning outputs for client discussions rather than a general-purpose tax filing tool.
The planning depth is centered on scenario modeling. Users can compare multiple tax-planning scenarios and apply Result Finder for what-if analysis, which supports evaluating alternatives across a longer planning horizon. W-4 withholding calculations add a practical payroll-planning component, while federal and state projections extend the analysis beyond a single jurisdiction. These capabilities make Planner CS a strong fit for firms handling multi-year planning, state complexity, and client-facing recommendations.
Ecosystem fit is a defining consideration. Planner CS imports client data from UltraTax CS and GoSystem Tax RS, and Thomson Reuters offers hosted cloud access through Virtual Office CS and Software as a Service for CS Professional Suite. According to the vendor’s pricing model, prospects contact sales rather than selecting a published plan online. Firms already working with the supported Thomson Reuters tax systems should find the product’s workflow alignment more relevant than firms seeking broad integrations or a standalone consumer tax application. Choose Planner CS for professional tax projection and scenario work; look elsewhere if your needs are limited to basic individual tax preparation.
