Taxation originated as a means to finance the activities of government, and that still remains its primary purpose in most of the world. However, in recent years, taxation also has been used to discourage undesirable behaviour or encourage socially desirable activity. In some cases, these policies take the form of a “user fee,” in which the taxpayer is charged for specific activities, such as a charge to dump garbage in a landfill. These fees should serve as a deterrent that would discourage the activity or behaviour. In addition, these fees may be designed to pay, at least in part, for the cost of the activity to the government. In other cases, a reduction in taxes is given to encourage desired activities or behaviour.
Discussion
(a) Adam smith principles of a good taxation system
Adam Smith developed the basic principles that should be subject to all legal and tax rules in order to integrate a fair legal system that encourages productivity, effort and creative imagination as sources of wealth. These principles are:
Principle of Justice and Proportionality;

The time of payment, the payment, the appropriate amount, everything must be clear and precise same for the taxpayer to any person, given the uncertainty accommodate the abuse and corruption favours certain people who are unpopular in the nature of their positions, even if they do not engage in corruption and abuse.
3. Principle of Comfort
This principle provides that any tax should be collected over time and how be more comfortable for the taxpayer, which means that the deadlines and dates should be set so that taxpayers will be practical and not very burdensome the fulfil their tax obligation.
4. Principle of Economy
This principle is that any contribution should be levied so that has the smallest possible difference between the amounts that come out of the pocket of the taxpayer and they enter the public treasury (William, 2005, pp 362).
