Federal Inland Revenue Service (F.I.R.S): Overview, function and salary structure

The Federal Inland Revenue Service started as part of a colonial tax organization under the name the Inland Revenue Department of Anglophone West Africa. The Federal Inland Revenue Service (FIRS) is the only government institution at the federal government level in Nigeria saddled with the aim of collating and collection of  FG Taxes across the country. Let’s check out the functions of the Federal Inland Revenue Service (FIRS).


The Nigerian Federal Inland Revenue Service was created in 1943, when it was carved out of the erstwhile Inland Revenue Department that covered what was then the Anglo-phone West Africa (including Ghana, Gambia, and Sierra Leone) during the colonial era. In 1958 the Board of Inland Revenue was established under the Income Tax Ordinance of 1958. After various transformations in 1961 and 1993, Federal Inland Revenue Service (FIRS) as the working arm of FBIR, secured its autonomy through the emergence of FIRS (Establishment) Act 13 of 2007. The commencement date of this Act was 16th April 2007. The Act is a compendium of establishment, powers, management, financial provisions, tax administration and other provisions guiding the administration of FIRS.
