A Multiple Regression Analysis Of Contributions Of Various Sources Of Tax To The Total Tax Revenue In Nigeria:- Usoro, Anthony E.
ABSTRACT
This
work sought to carry out a multiple regression analysis, which involved a
dependent and five independent variables. The data for the analysis were
obtained from Federal Inland Revenue, Uyo Zonal Office, Akwa Ibom State.The
variables Ci, C2, C3, C4, C5 and Cg, which represented Total Budgeted Tax
Revenue (TBTR), Petroleum Profit Tax (PPT), Company Income Tax (CIT), Education
Tax (ET), Personal Income Tax (PIT) and Value Added Tax (VAT) respectively were
all used for the analysis. A multiple linear model was obtained as; Ci =
20.017-0.342C2 -1.115C3 17.633C4 +17.171C5 +0.51C6. The t-test result of
table 4.2 revealed that Petroleum Profit Tax and Education Tax are
statistically significant while Company Income Tax, Personal Income 8 Tax and
Value Added Tax agreed with the null hypothesis of no significant contribution
to the Total Tax Revenue. Farrar and Glauber test for detection of
multicollinearity showed presence of multicollinearity amongst the explanatory
variables. Further tests carried out indicated that the presence of
multicollinearity was as a result of inter-correlation between variables C2 and
C5. This . multicollinearity attracted further study to finding solution
through Principal Component Method. The Principal Component Analysis was actually
carried out and this finally yielded higher estimates for Total Tax Revenue.
