Good day everyone,

If you are currently having issues with the new update for ZIMRA VAT being changed from 15% to 15.5% (as of January 1st 2026), the following instructions are on how to update it on your Fiscal Harmony Template. This also includes any issues involving updating the tax ID on the configuration where it notifies the user that it is failing e.g. "Tax fiscal lD no longer available : 1" for example.

How to update it on your template

Step 1: Navigating to the configuration

• Open your Fiscal Harmony Invoice template from the File menu or the menu where you create a new file.
• When the file is open, navigate to the Fiscal Harmony tab and select it
• On the tab, select Manage Accounts. This should open a window to show the details with your account and API keys.

Step 2: Performing the updates

• In this window, you do not have to change anything. Make sure you have an internet connection and hit the "Save" button so that the system will update automatically.
• When the application confirms the save, close Excel and then Reopen Excel.

Step 3: Confirming changes

• Open the template again and navigate the column with the VAT tax. If you click on the cell's dropdown, you should be able to see the new VAT tax rate.
• Check your other invoices for 2026 to see if the invoices have been updated as well.
• You may make a test invoice to see if the changes are reflecting with the new Tax.
