CCH ProSystem fx Planning review
A deep CCH-connected planner for firms modeling complex federal and state tax outcomes.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CCH ProSystem fx Planning is tax planning software for CPA and public accounting firms. It combines federal calculations—including regular tax, AMT, capital gains, and retirement-distribution taxes—with integrated state computations for individual income tax authorities. Firms can also model estimated taxes, underpayment penalties, retirement-plan contribution deductibility, deductions, exemptions, credits, and carryforwards. Its audience is tax professionals who need structured planning workflows for individual clients and complex what-if analysis.
The product’s strongest capability is scenario modeling. Each tax scenario can contain up to 10 years of data, while users can compare up to 30 scenarios. Percentage- and dollar-based plan variance analysis helps show how proposed changes affect outcomes. Retirement calculations cover IRA, SIMPLE, SEP, and KEOGH contribution deductibility, and estimated-tax work includes payment vouchers. This makes the product a fit for firms handling multi-year planning, capital gains, retirement distributions, and estimated-payment decisions rather than only basic tax projections.
CCH ProSystem fx Planning is particularly suited to firms already working with CCH Axcess Tax or CCH ProSystem fx Tax, because it can import base-year amounts from both products. Support channels include email, chat, and phone, and the product is positioned for small, mid-market, and enterprise organizations. The published buying path directs firms to request a quote, so prospective buyers should assess fit within their CCH environment and procurement process. Choose it for deep CCH-connected tax scenario analysis and client correspondence letters; consider an alternative if in-product client collaboration or a non-CCH-centered workflow is a priority.
