Apply the missing VAT rate 1. Apply the missing VAT rate If you forgot to apply the 7% rate, you can add it to the header and select "VAT only" so that Sage updates the relevant lines without affecting other accounting settings. 2. Set rates in the item library To avoid this type of error in the future, you can associate each item with a specific VAT rate in the library. This way, when you enter the rate, Sage will automatically apply the correct rate based on the selected item. 3. Create custom rates in Sage In the setup module, you can create multiple VAT rates (e.g., 5.5%, 7%, 19.6%) and make them available for all documents. This makes it easier to select them and prevents forgetfulness.
