Adam Smith laid down four principles or cannons of taxation in his famous book "Wealth of Nations"
Canon of equality or ability
People should pay taxes in proportion to their incomes, with the rate or percentage of taxation increasing with the increase in income and decreasing with the decrease in income
Canon of certainty
There should be certainty with regard to the amount which taxpayer is called upon to pay during the financial year
Canon of convenience
The tax should be levied at the time and the manner which is most convenient for the contributor to pay it
Canon of economy
The expenses of collection of taxes should not be excessive and should be kept as little as possible, consistent with administration efficiency
Other principles of taxation
Canon of productivity
Canon of elasticity
Canon of simplicity
Canon of diversity
Proportionate principle
Taxes should be levied in proportion to the incomes of the individuals to extract equal sacrifice
Modern principles of taxation
Rational combination of direct and indirect taxes
Universalization of taxation
One-time taxation
Scientific approach for the determination of the exact tax rate
Universalization of taxation
Equivalent efficiency requirements to all payers and an equivalent approach to the deduction of the tax amount irrespective of the income source, type of activity, or economic sector
It is not acceptable to introduce additional taxes, increased and differentiated rates, or tax allowances for different types of ownership, organizational or juridical structure of the entity, citizenship of natural persons or other factors
Taxes should not be established or applied on basis of political, economic, and ethnic factors, or other criteria of this type
One-time taxation
One object can only be taxed once through one tax type for a specific period of time indicated in the law
Scientific approach for the determination of the exact tax rate
Setting the deduction rate at a level that would allow the subject to have an income necessary for normal development
The magnitude of the tax burden should allow the normal functioning of the taxpayer after paying the tax amount
It is not acceptable to set the tax rates on basis of short-term interests of insuring state revenues and to the detriment of economic development or to the interests of the taxpayer
Stability of taxation
Endurance of taxation for a long period of time and the simplicity of deducting the payment
Tax rates should be determined by law and should not be revised frequently
Differentiation of tax rates
In accordance to the level of income, which should not develop into an inhibitive progression nor should it be transformed into an individualization of rates
Tax allowances system
Lead to an actual stimulation of investments into entrepreneurship activities and comply with the principle of social justice, including the insurance of a minimum living standard of the citizens
Allowances should not be established for certain payers only—they should be the same for everybody
Benefit Theory
The state should levy taxes on individuals according to the benefit conferred on them
The benefit theory has been subjected to severe criticism as there is no direct quid pro quo in the case of a tax, and it is not possible to estimate the benefit enjoyed by a particular individual every year
Cost of Service Theory
The state charges actual cost of the service rendered from the people
The cost of service principle can be applied to some extent in cases where the services are rendered out of prices and are a bit easy to determine, but most of the state expenditure cannot be fixed for each individual
Ability to Pay Theory
Citizens of a country should pay taxes to the government in accordance with their ability to pay
The main viewpoints on measuring ability to pay are ownership of property, tax on the basis of expenditure, and income as the basis
Keynesian Taxation Theory
Fast economic development must be based on a market expansion and an associated increase in consumption, and state intervention is achieved at the level of effective demand
Keynes argued that high level progressive taxation is necessary and that low tax rates lead to reduced state revenues and contribute to economic instability
