A VAT amount is not allowed if you use a VAT code of type No VAT or VAT 0 percent. ## Error message ```plaintext Failed to export expense. A VAT amount is not allowed if you use a VAT code of type 'No VAT' or 'VAT 0%'. ``` ## Affected ERP integrations - Exact Online ## Cause This error occurs when you have selected a VAT code in Payhawk that is designated as **No VAT** or **VAT 0%** in Exact Online, but a custom VAT amount (greater than 0.00) has been entered for the expense in Payhawk. Payhawk's logic for handling VAT amounts is as follows: - If you select a VAT code, Payhawk typically calculates and displays the appropriate rate, sending only the VAT code to Exact Online. - If you manually override the calculated VAT amount in Payhawk to a different value, Payhawk will send both the VAT code and the custom VAT amount to Exact Online. When a VAT code that means **no tax**, such as **No VAT** or **VAT 0%**, is paired with a non-zero VAT amount, Exact Online identifies this as a discrepancy and blocks the export, as it's logically inconsistent to have a VAT amount when the rate is zero. ## Solution To resolve this issue: 1. In the [Payhawk Web Portal](https://portal.payhawk.com), go to **Spend**. 2. Click on the expense that failed to export. 3. Locate the **VAT code** and **VAT amount** fields. - If the expense truly has no VAT, ensure the selected **VAT code** in Payhawk is indeed a **No VAT** or **VAT 0%** type. Change the VAT amount to **0.00**. - If the expense should have VAT, change the selected **VAT code** in Payhawk to an appropriate code that has a non-zero VAT rate configured in Exact Online. Adjust the VAT amount accordingly. 4. Save the expense and attempt to export it again.
