System Requirements for TaxCalc

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

• 10
• 8 / 8.1
• 7 (Service Pack 1)
• 2008R2 (2008 before R2 is not supported)
• SBS Server 2011
• Server 2012
• Server 2016

Apple Mac (64-bit Intel processors only)

• 10.14 Mojave
• 10.13 High Sierra
• 10.12 Sierra
• 10.11 El Capitan

Linux

• 64 bit kernel 3.10 (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.

• 10.10 Yosemite

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.

Unsupported

For more information on our unsupported operating systems, please see our Knowledge Base article for Retired Operating Systems

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.
