What are the system requirements for ProSeries Tax and ProSeries Tax Basic Edition?

Based on continued performance testing, we have increased our minimum RAM requirement to 8GB. If you are running ProSeries on a computer with less than 8GB of RAM, you will experience slower performance when opening the program and completing tax returns. To improve performance, we recommend upgrading your RAM to 8GB or more.

  • While some Customers run ProSeries in a Windows emulation environment (i.e Virtual Machine) on the Apple MacOS operating system, support for this type of install may be limited. Customers using the Apple MacOS may wish to use our online or hosted software options instead. See for more information on ProConnect Tax for our online tax product or Tax Software Hosting for ProSeries.
