Is tax added to the price?

Tax is never added on top at the end: what you see is what you pay.

In the United Arab Emirates

5% VAT is included in the price shown, not added at checkout. Your tax invoice shows the VAT on a line of its own, from Anunzio International FZC with the company's tax registration number on it.

Everywhere else

Nothing is added to the price at checkout, and your tax invoice is marked OUT OF SCOPE: outside the scope of UAE VAT. It carries the amount charged.

Every invoice states exactly what was charged and what part of it, if any, was tax. See Where are my invoices?.

Your company's VAT number

Every invoice has a Customer VAT number line, in the UAE and everywhere else. It shows your number, or N/A when we do not have one.

To add it, open Billing, type it under VAT number in Payments and invoices, and press Save. Type it the way your tax office gives it - in the UAE that is your TRN - using letters, numbers, spaces or dashes (4 to 20 of them). It goes on the invoices for your payments from then on, printed cards included; invoices already issued stay as they are. Only the account's owner can change it.

You can also type it on the payment page when you buy. The number given last is the one used: a number typed on a payment page goes on your invoices from then, and pressing Save under VAT number takes its place again - your number, or N/A if you leave the field empty. If your last invoice shows a different number, Billing says so under the field.
