If your requirements for the system change whilst you have an active license, it may be best to clarify your yearly requirements with a member of our Sales team. The reason for this is that the licences purchased will activate for a 12 month period and therefore you should consider what you will need over the course of this time period. The contact details can be found below:
If however you know which product you need to purchase, you can simply log in to the TaxCalc website and purchase the required item(s). please note that any existing products will need to be removed (the website will issue a pro rata credit for the remaining time left on your licence towards the cost of the upgrade) and therefore you should ensure that if necessary, the existing product is re-added in the order. Once the payment has been processed, you should close and re-open the TaxCalc application and the new licence will start with immediate effect.
