Descriptive and inferential (multiple regression) statistics were used to analyze the data at 0.05 level of significance. The study revealed that government expenditure on roads (Adj.R2 = 0.806, F (5, 21) = 25.097, p < 0.000) and government expenditure on power (Adj.R2 = 0.742; F (5, 21) = 17.63; p <0.05) were significantly affected by federal tax revenue.
