The actual tax to be paid may be modified by TaxExemptions, that can apply to:<br/>        • A Party – for example a war veteran may be granted a partial exemption from purchase tax, to pay 7% instead of 15%, or a voluntary organization may be granted a complete exemption from value-added tax, to pay 0%.<br/>        • A Location – for example a disadvantaged neighborhood may be granted a partial exemption from purchase tax, or a tourist zone may be granted a complete exemption from value-added tax.<br/>The TaxExemption will be issued by the same TaxJurisdiction that levies the tax, and will typically be represented by some certificate of exemption that has an ID and perhaps a printed or electronic representation to attest the granting of the exemption.<br/>The amount of the exemption is determined in the same way as the tax amount itself, by simple or complex calculation.<br/>
