Intergovernmental Relations in Tax Administration in Nigeria. The need for the Federal Government of Nigeria and its state governments to mobilise internal
revenues has become inevitable owing to dwindling revenue from oil. The National Economic
Council Retreat of March 2016 had within its 71 Resolutions, a dedicated theme on Revenue
Generation and Fiscal Stability. The Technical Report of the Retreat has suggested that for Nigeria
to attain the average revenue to GDP ratio of similar economies, it has to increase its tax revenues
by 300% from the less than 7% to 20% of GDP, and that at least 70% of its revenues must come
from non-oil sources to ensure sustainability and forestall the country’s exposure to shocks in oil
prices.
