Sources of Nigerian Tax Law

Nigerian Tax law, in line with best global practice is purely statutory. Therefore, main domestic sources of tax law are primary legislation, such as acts or laws, and secondary legislation (interpretation of tax laws) such as rulings, decisions, circulars, orders, etc. The main international sources of tax law are bilateral or multilateral treaties, and one important source for the interpretation of treaties is the OECD model tax treaty and the accompanying commentary. Another model is UN model. We shall examine these diverse sources. We have grouped these overlapping sources into the aforementioned distinct heads and seek to examine them in this paper.
