Tax Policy and Administration

While any evaluation of tax policy and tax administration is naturally centred around revenue, due consideration must also be paid to the public expenditure environment, particularly with respect to whether expenditure leads revenue or vice versa. It is possible to have both good tax policy and good tax administration, with public expenditures being spent on dubious projects - which ultimately equals poor policy. Potential conflict between tax policy and tax administration is important to anticipate. In this regard, the forum within which tax policy is set is significant. Experience has shown, for example, that policy should not be determined by the institution responsible for administration (a conflict of interest exists between achieving revenue targets and establishing good policy).

Both tax policy and tax administration can be assessed against the norms of good practice. The combination of the "good" tax and the "good" tax administration provides a basis for an evaluation of the way taxation is conducted in any country.

Taxes are unrequited, compulsory payments collected primarily by central government, in contrast to user charges that are payments in exchange for specific publicly provided goods. In principle, charges should be used wherever a publicly produced good or service can be sold and should reflect some measure of the cost - preferably, the incremental cost. Tax financing should be reserved for cases where user charges are not appropriate to pay for public goods. These include goods whose costs or benefits cannot be assigned to individuals; compensation for market failures (such as externalities); or for the achievement of distributional goals (such as alleviating poverty).

Since the primary function of the tax system is to generate revenue, its first goal is to ensure that this function is discharged effectively. A second goal is to raise the economic efficiency of the taxation system. This requires that, for a given level of revenue, it interferes as little as possible in decisions made by firms (about production, trade and investment) and by households (about consumption and savings). A third goal is to lift the tax burden off the poorest households and to ensure that actual tax structures are both horizontally and vertically equitable. This is likely to be carried out with some degree of progression.

Any reform or redirection of the tax system is likely, as its main aim to simplify tax policy and strengthen tax administration to achieve these objectives in the most efficient manner. The imposition of individual taxes in any country should ultimately be determined by the capacity of the tax authorities to administer the tax system efficiently and effectively. Some taxes, while theoretically sound, should not be contemplated as the cost of collection may be too great in relation to tax yield and the imposition of the tax may not be equitably applied to all the taxpayers that should come under that tax’s net. In addition to this a widespread use of exemptions ensures that the tax system deviates from the "good" tax model from the principles of both equity and administrative efficiency. The proliferation of exemptions is a condemnation of the basic principles underlying the tax that is being exempted. The granting of exemptions creates a culture of expecting and seeking exemptions. It is better to reform the system rather than continue to allow the undermining of good tax administration by creating the conditions for the continuation of an exemption culture.

There is also one important feature of a tax system that has to be added to the above: that of stability. Unfortunately, a stable "bad" tax system is not desirable. Stability can only be justified when the system has been adequately established and/or reformed. Once the system has been through an appropriate and adequate reform process, then it should be left substantially unchanged.
