Please see below the step by step instructions on how to change a password for TaxCalc users (other than admin).
Open TaxCalc and log in with your admin username and password
Launch Admin from the home screen.
Step 3: Open the Users Admin Panel
When Administration opens, select Users from the left-hand menu.
The screen will show the user accounts that have already been created. If TaxCalc has just been installed it will just show the admin account.
Right click on the username you want to change the password for. Enter the password you want them to use.
Please Note: If you are resetting someone else's password, this is a one use password and will have to be changed the first time the user tries to log in
Click on Reset.
The next time someone logs in using the relevant username, they need to enter the password you set in Step 4 above. They will then be prompted to set their own password that they will use going forward.
