All perks contribution amount includes taxes (if applied).
The value added tax (VAT, IVA in Spain) is included for Spanish clients and also for some European countries as law stablishes, meaning that the price you are paying includes the machine and the taxes.
In case you are an American client, VAT is not applicable, and the price you are paying through Kickstarter includes the machine.
So, depending on your country the invoice will contain the VAT or not. Once the campaign ends, the invoice sent to all our backs will contain a detailed specification of the taxes applied depending on the case.
