Frequently asked questions

The questions below provide immediate answers to many aspects of TaxCalc Tax Return Production.
If you have any further questions, please call 0345 5190 883 or email

Does TaxCalc work on
Windows 10?

Yes. TaxCalc's software has been fully tested with Microsoft's latest operating system and we can confirm that it does indeed work with Microsoft Windows 10. For a full compatibility list please see the System Requirements for TaxCalc.

Does TaxCalc work on
Apple Macs?

Yes. TaxCalc will run on any 64-bit Macintosh running Mac OS 10.7 or higher.

Does TaxCalc work on Linux

Yes. TaxCalc will run on any 64 bit kernel 3.2(or higher), Debian (e.g. Ubuntu) or Redhat based distributions.

Will you release a server
version for Apple Macs?

We will wait to gauge the popularity of the standalone version before deciding whether there is enough support to embark upon creating a server version. Again, please email our support team at to register your interest.

Do I have to buy the
software every year?

TaxCalc is an annual purchase because we have to redevelop it each year for new rates
and tax rules. We also continually improve the product and release a series of updates during
the course of your licence.

Your software will run for a full twelve months and you will be invited to renew your licence 30 days before it expires. If you renew within this period, some products will be entitled to an early renewal discount.

Furthermore, we believe in fair, transparent pricing and sales terms. That's why we don't lock you into long contracts or require lengthy notice periods to leave us (not that you would!).

Can I upgrade or add
additional returns?

Yes. You can start off working with one version of TaxCalc Tax Return Production and later upgrade or buy a version that provides additional returns. We will provide you with a credit for any unused portion of your annual licence.

If you cannot find the product you are looking for, please call us on 0345 5190 883 or email

Will I need to reinstall
if I upgrade?

We make it easy for you. All you need to do is pay for your upgrade and restart TaxCalc on your computer. Your software will be updated automatically.

Can I move from the
standalone version to the
server version?

Yes. Whilst you can do this by yourself, we also offer a migration service, charged based on the complexity of your standalone deployment (for example, to merge many standalone databases).

Can I buy previous
years' returns?

All TaxCalc Tax Return Production products create tax returns for tax years from 2011-12. We have a range of standalone products for tax years prior to this. Please call us on 0345 5190 883 or email to discuss your requirements.
