Duo Tax FAQ

What is a Value-Added Tax (VAT) number?

A Value-Added Tax (VAT) number, also known as Goods & Service Tax (GST), is a registered tax identification number in a country with a tax system that utilizes VAT. When a business registers for VAT in their billing country, that business receives a VAT number for that country’s tax system. A VAT number is exclusively used for the VAT scheme. A VAT number usually has between 4 and 15 digits, and starts with the two digit country code (e.g., DE for Germany, IN for India), followed by 2-13 other characters, (i.e., DE123456789).

Is Value-Added Tax (VAT) included on Duo invoices?

Currently, Duo does not charge a Value-Added Tax (VAT). Reverse charges may apply.

Why is Duo prompting customers to provide their Value-Added Tax (VAT) number?

Many non-US tax authorities require that a customer’s Value-Added Tax (VAT) number be listed on their invoice. Requiring this field for non-US billing customers, when a customer first registers, or, when the customer updates their billing information, enables Duo to comply with this common requirement.

What if a business has multiple Value-Added Tax (VAT) numbers?

The Value-Added Tax (VAT) number provided to Duo should be the one associated with that customer’s billing country listed on its Duo account.

Does the customer’s Value-Added Tax (VAT) number provided to Duo need to match that customer’s billing name on its Duo account?

Yes, the Value-Added Tax (VAT) number provided to Duo should match that customer’s billing name on its Duo account.

What if a business does not have a Value-Added Tax (VAT) number?

If a business does not have a Value-Added Tax (VAT) number, it should bypass the “VAT Number” field by selecting the prompt: “I do not have a VAT number.” Next, the business should select a reason for not having a VAT number from the following options:

• “My country does not require VAT numbers”

• “I have not yet met the requirements to become a VAT registrant in my billing country”

• “Other” (Type other reasons here)
