  • You only need to install UltraTax CS one time. You do not need to download and re-install the entire application to install any subsequent updates. See Installation Instructions for 2017 UltraTax CS.
  • After installing the initial release from our website, UltraTax CS automatically downloads and installs subsequent releases and updates for your licensed products via CS Connect Background Services, which is enabled by default.
  • If you have disabled CS Connect Background Services, you can install updated applications by opening CS Connect and downloading and applying releases and updates manually
  • In many cases, the releases of UltraTax CS applications (especially states) are contingent on the federal or state governments and taxing authorities. Tax law changes, pending legislation, and the approval of updated tax forms can all impact a release date. For details regarding federal and state UltraTax CS releases, click the Product Releases link on left side of the UltraTax CS Home Page, then hover your mouse pointer over a state application's checkbox to view the planned release date.
