# Submit a tax exemption certificate


If you're a customer in the United States and are exempt from sales tax, you
can submit a valid tax exemption certificate to Docker Support.

If you're a global customer subject to VAT, make sure to include your
[VAT number](/billing/history/#include-your-vat-number-on-your-invoice)
along with your country prefix when you update your billing profile.

## Prerequisites

Before submitting your certificate:

- The customer name must match the name on the certificate.
- The certificate must list Docker Inc. as the Seller or Vendor, with all
  relevant fields completed.
- The certificate must be signed, dated, and not expired.
- You must include the Docker ID or namespace(s) for all accounts to
  apply the certificate to.

> [!IMPORTANT]
>
> You can use the same certificate for multiple namespaces, if applicable.

Use the following contact information on your certificate:
