TaxCalc will include software updates regularly that are downloaded from the internet. This will include improved stability to the product and any new additional functionality that may have been added. The application will check for updates and licence terms each time it starts up on the computer. We recommend that you update your software on a regular basis. To check which software version you are running and for further information on how to update, please see How do I check if my TaxCalc is up to date?
