A Multiple Regression Analysis Of Contributions Of Various Sources Of Tax To The Total Tax Revenue In Nigeria
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 lbom State. The variables C+, C», Cs, Ca, Cs and C,
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; C, = 20.017--0.3420% - 1.1150% +
17.633C, + 17.171C% +0.51C%. 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 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 Cs. These 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 .
