Ultra Tax CS – Thomson Reuters

From the 2020 reviews of professional tax preparation systems.

UltraTax CS from Thomson Reuters is part of the CS Professional Suite of applications. UltraTax CS is better suited to larger firms that process more than 250 tax returns annually. For smaller firms that process fewer returns, Thomson Reuters recently released UltraTax CS Express (not reviewed here), a scaled down version of the application that offers e-filing capability for up to five states and up to 250 returns.

While UltraTax CS can be used as a stand-alone application, more product functionality can be utilized if used in conjunction with other CS Professional Suite applications. Currently, UltraTax CS can be installed on-premise, accessed through Virtual Office CS, or delivered as a SaaS solution.

While UltraTax CS does not offer a mobile app, those using other CS Professional Suite applications such as NetClient CS and Practice CS can access client returns, financial statements and other related documents via a smart phone or tablet.

What’s New

UltraTax CS offers several new enhancements including the Connect Background Services, which offers automatic downloading and application of updates directly to the UltraTax CS Bar Code Scan utility and the Data Entry utility. A new user preference option has been added to the list of options which will warn users when a client has been closed. One update in the application is actually the removal of a feature – the Recall Transmitted Returns option will no longer be available due to the immediacy in which the IRS now accepts e-filed returns.

UltraTax CS has also added links to the Help and How-to Center for any e-file rejections to help with troubleshooting and form correction. Google Maps integration has been added to the application, and changes to the asset module allows users to calculate change of use on multiple assets at one time.     

Product Features

E-Filing is completely supported in the application for both federal and state returns where e-filing is permitted. FinCEN Form 114 e-filing for foreign bank reporting supported as well.
