A value added type tax (VAT) is a tax on goods and services collected in stages by enterprises and which is ultimately charged in full to the final purchasers. This heading value added type taxes comprises the value added tax which is collected by the General government and which is applied to national and imported products, as well as, where appropriate, other deductible taxes applied under similar rules to those governing VAT, for simplicity henceforth called ‘VAT’. Producers are obliged to pay only the difference between the VAT on their sales and the VAT on their purchases for their own intermediate consumption or gross fixed capital formation.
