Indirect taxation is increasing in prominence worldwide. In times of international company tax competition, such forms of indirect taxation as value added tax (VAT) and goods and services taxes (GST) are particularly advantageous as sources of tax revenue on account of their broad base and non-distortion of competition in the chain of companies.
