# VAT information required error when submitting an invoice with tax information

## Symptom

When submitting an invoice, I receive the error VAT information required even though I already entered tax information.

## Environment

SAP Business Network

## Cause

Your buyer has enabled the two rules below, but they have not added a tax with the value **VAT**.

- Sub-rule **Require VAT** for rule **Require suppliers to provide tax information in invoice**.
- **Require suppliers to choose from your list of valid tax values.**

Since your buyer requires a value of VAT and is expecting a value from their list of valid taxes, the invoice returns an error because there is no **VAT** value available for you to select on their list of valid taxes.

## Resolution

You must [contact your buyer](https://support.ariba.com/item/view/KB0392552)to request one of the following two actions be taken:

1. Disable the sub-rule **Require VAT** for the rule **Require suppliers to provide tax information in invoice**. OR
2. Add a **VAT** value to their list of valid taxes.

Once one of these actions is completed, you must submit a new invoice with the proper tax information.

## See Also

As Australia suppliers do not use **VAT**, if encountering the above error, another option to finish the validation is using **ABN number** as **VAT**.

1. Click the **\[user initials\]** on the top right corner of SAP Business Network home page.
2. Click **Company Profile >** **Business Information** tab.
3. Input your **ABN** number into **ABN Number** and **Vat ID** fields.
4. Tick the checkbox of **VAT Registered**.
5. Click on **Save**.

If you want to check which transaction rules your buyer has set for you, follow the article [How do I view the transaction rules set by my customer in SAP Business Network?](https://support.ariba.com/item/view/KB1395929)
