Failure to render, such service usually resulted in Seizure of property which might be reclaimed on payment of money. This practice continues until 1904 when late Lord Lugard introduced the first income tax into the system. With the emergence of the Native Revenue ordinance of 1917 and subsequent amendment, the income tax became operative in the southern Nigeria in 1918 precisely Abeokuta in the Western Nigeria and Benin city in Mid-Western Nigeria and by 1928, it has extended to the Eastern Nigeria. With the passages of time the Native Revenue ordinance of 1917, 1918 and 1928 were transform into Direct Taxation Ordinance in 1940 and this automatically replaced the Nature Revenue Ordinance and the Native Direct Taxation (Colony) of 1937 which of course was regarded as been discriminatory in nature for the fact that it only applies to native in Nigeria other than Lagos Colony or township.

Tax laws or Acts in Nigeria came into being as a result of lack of uniformity in the tax collection system as observed between the Africans and non – Africans living in some part of the regions of Nigeria most especially Lagos Territory.
