Why is Value Added Tax Charged on my Invoice.

[mmikestone]

I do not understand why VAT (Value Added Tax. A UK Sales Tax.) @ 20 % is charged on sales.

I was about to purchase Mezzmo when I noticed this.

Concevia is an Australian Company and the money handler -Digital River is in California.

Having purchased Software before off the net I have NEVER been charged VAT on it.

Could a Representative of Concevia inform me why they want to add 20% to my invoice? Are They VAT registered?.
And more importantly do they remit this Tax to the UK government after collecting it.
