113 years of SIXT. 113 years of tradition.

How do I change the VAT details or address on my SIXT invoice?

Invoices and receipts

You can update your billing address on the website or in the SIXT app within your booking at any time – both before pick-up and after return. A VAT number, however, cannot be added on the website or in the SIXT app – just message us on WhatsApp or Live Chat and we'll add it for you.

Add or update your billing address on the website or in the SIXT app

  • Sign in on the website or in the SIXT app

  • Open "Bookings" and select the relevant rental

  • In the "Your information" section, click "Add billing address"

  • Enter the company name and address and save

Tip: In the "Profile" section, you can save your company details and billing address as defaults – they'll then be used automatically for any future bookings.

Add a VAT number

A VAT number can't be added by yourself on the website or in the SIXT app via your booking management. Just message us on WhatsApp or Live Chat with your rental agreement number and the correct VAT number – we'll add it and send you an updated PDF invoice by email.

Exception: corporate rentals with a fixed billing address

For corporate rentals with a fixed billing address on file, changes can't be made on the website or in the SIXT app. Just message us on WhatsApp or Live Chat with your rental agreement number – we'll check whether an update is possible.

Next step

Update your billing address on the website or in the SIXT app under "Bookings", or have it added or reviewed via WhatsApp or Live Chat.
