Explanation:

El impuesto del 12% sobre compras o consumo es el impuesto al valor agregado. In Spanish it's commonly known as IVA, because of its initials. In English it's the value added tax. The percentage varies according to each country. In Argentina, for instance, it's a 21%. It's very common for tourists to have it back when purchasing things abroad, this is the famous "tax free". It's a benefit for people who purchase goods but don't live in the country where they're buying those things.
