# Adding VAT rates with DATEV BU codes

In many cases, the tax amount on the document is not the actual amount your company can claim. The supported [integration between Payhawk and DATEV](/help/connecting-payhawk-to-duo) automatically creates the **BU7**, **BU8**, and **BU9** VAT rates. However, you can add your own, custom VAT rates (BU codes) in Payhawk.

> [!TIP]
> All of your VAT rates will appear in **Spend**. When a new expense is created, it will use the default VAT rate from the expense category. You can set [default VAT rates](/help/creating-editing-and-deleting-default-tax-rates) in the categories.

## Creating new VAT rates in Payhawk

To create additional custom VAT rates (BU codes):

1. Log in to your Payhawk account.
2. Go to **Settings** > **Fields library**.
3. Click on **Tax rate**.
4. Click on **Add rate** and, in the **New tax rate** panel, enter the desired VAT name in **Name**.
5. In **Code**, enter the **BU-Code** from DATEV.
6. Enter the rate in **Rate %**.
7. Click on **Save*.***

## Editing or deleting existing tax rates from Payhawk
