System Requirements for TaxCalc

Article ID: 2066
Last updated: 02 Mar, 2017

TaxCalc is either ‘fully supported’, ‘partially supported’ or ‘unsupported’ running on the configurations of operating system as listed here.

Fully supported

TaxCalc is optimised to work on the specified versions of these operating systems and all releases are tested on them.

Microsoft Windows

Apple Mac (64-bit Intel processors only)


  • 64 bit kernel 3.2 (or higher), Debian (e.g. Ubuntu) or Redhat based distributions
  • Graphical user interface (GUI)
  • Office productivity software (for Word and Excel exports)

We fully support customers with TaxCalc queries encountered when running on these configurations and we endeavour to correct any issues that emerge.

Appropriate hardware is required to run any operating system.

Partially supported

TaxCalc may work perfectly well on the following platforms but we cannot guarantee it.

  • There are no operating systems which are partially supported

Releases are tested on these configurations and we will make reasonable efforts to support customers with queries encountered on them but we may not be able to correct any issues that emerge.

These operating systems will usually be no longer supported by their suppliers, making them vulnerable to security threats. As a result it may become necessary for us to make changes to TaxCalc with minimal or no notice that render it unable to run on a given partially supported platform.

For all these reasons we recommend that all customers move to a fully supported platform as soon as possible.


Microsoft Windows

  • XP
  • Server 2003

From 1 March 2016, support ceased for the above versions of Microsoft Windows. To find out more, please read article Withdrawal of Support for Windows XP and Server 2003.

Apple Mac

Any operating system not explicitly listed as ‘fully supported’ or ‘partially supported’ should be considered ‘unsupported’.

TaxCalc will probably not run on these platforms or, if it does, some functions may not behave correctly. No testing is performed and only limited support will be given to customers with queries or issues encountered running on these configurations.

These operating systems may no longer be supported by their suppliers making them vulnerable to security threats and we strongly recommend that all customers move to a fully supported platform immediately.

Program Compatibility

  • The Encrypted PDF module is not compatible with Mac or Linux operating systems.
  • Mac and Linux machines can act as clients connecting to the server and CloudConnect versions of TaxCalc, but cannot currently act as the "server machine" for TaxCalc.

Additional Requirements

  • A PDF viewer such as Adobe Reader 9.0 or higher (Adobe Reader 11.0.06 or above is required for Windows 8/8.1 and Windows 10).
  • Microsoft Office 2007 or higher for export and Mail Merge features.
  • An internet connection to allow the product to be licensed to you, receive updates and file online.
  • A minimum screen resolution of 1024 x 768.
