The demo database allows you to practise using TaxCalc on a separate standalone database and trial its features without having to enter lots of data.
To use the demo database, follow these steps:
TaxCalc will close and reopen to give you the demo database. This will include all the modules for which you have a (trial) licence.
NOTE: None of the changes you make in the demo database will be saved. If you want to save data or enter real client data, use the main database.
