The economist Adam Smith developed the following Canons of Taxation as principles which could ensure a good taxation system - Leaving Cert Economics - Question b - 2010

The economy canon emphasizes that the revenue collected from taxes should exceed the costs associated with their collection. This means that the administration costs should be minimized to ensure that as much revenue as possible is available for public services and welfare.

Certainty pertains to the clarity and predictability of tax obligations. The taxpayer should know how much they need to pay and when the payment is due, thus avoiding confusion and ensuring compliance.

Convenience in taxation means that the process of paying taxes should be straightforward and easy for the taxpayer. Taxes should be collected in a manner that is easy and not burdensome.

One additional principle to consider is Redistribution. This principle states that the tax system should aim to redistribute wealth within the country, aligning with the social goals of reducing inequality and providing for public goods. It can enhance social cohesion by ensuring that economic resources are equitably available.
