If you're hosted, we'll insert the new VAT rate into your VAT_Rate table on your behalf. If you're self-managed, we'll provide you with the script to run it yourself.
Here’s the information we’ll need:
Category Description: How it should appear e.g., Out of scope.
Code: For example, O
Rate: For example, £0.00
If you already have a default rate set to Yes in the table, we will check whether you'd like to switch it to "No" so your new rate can take the default flag. There must only be one default rate otherwise, interfaces may start duplicating rows.
We’ll assign the new VAT rate the next number in the display order sequence. For instance, if you already have four VAT rates with display orders 1–4, we’ll add the new one as position 5. We won’t leave this field blank.
The table also includes fields called External_VAT_Code and Additional_Code. If your interface uses these fields, let us know.
If you'd like us to make this change, please raise a new case.
