Adam Smith's four canons of taxation are: equity, efficiency, certainty, and convenience/simplicity. Use these canons as a framework to explain whether the personal property sales legislation (CB 3, CB 4, and CB 5) or the land sales legislation (CB 6 - CB 23) better meets Adam Smith's canons of taxation. You should refer to specific sections of the legislation and case law to support your arguments. While taxation has been around for a good number of centuries, the canons of taxation were first presented by Adam Smith in his famous book "The Wealth of Nations." These canons of taxation define numerous rules and principles upon which a good taxation system should be built. Although these canons of taxation were presented a good while back, they are still used as the foundation of discussion on the principles of taxation. Adam Smith presented 4 canons of taxation, which are also commonly referred to as the Main Canons of Taxation: 1. Canon of Equality 2. Canon of Certainty 3. Canon of Convenience
