The treatment of financial services has long been viewed as one of the more technical, and difficult, areas in value added taxation. Financial intermediaries add value by reducing transaction costs for clients. While in principle this value added should be taxed under a comprehensive VAT, this has proven to be difficult to do in practice because of measurement issues. The predominant approach adopted in most countries albeit with several variations on the theme has thus been to exempt most financial services from VAT. This was the approach adopted in Canada at the initiation of the GST just over twenty years ago. While this approach is far from perfect, and introduces several distortions into the economy, it has by and large been concluded that it is the most practical approach to dealing with financial services under a VAT.
