Based on Table 6.15, estimated regression showed that estimated coefficient for<br />

constant, B2, B3, B6, B7 <strong>and</strong> B8 were statistically significant at 1% level (p value <<br />

0.01). The B3 <strong>and</strong> B8 variables had a positive effect on <strong>tax</strong> <strong>compliance</strong> while B2, B6<br />

<strong>and</strong> B7 had a negative relationship with <strong>tax</strong> <strong>compliance</strong>.<br />

Results implied that <strong>tax</strong>payers with good <strong>knowledge</strong> about responsibilities, child<br />

relief <strong>and</strong> rebates tend to be non compliant with negative coefficient .53, .12 <strong>and</strong> .12<br />

respectively. On the other h<strong>and</strong>, <strong>tax</strong>payers with good <strong>knowledge</strong> of employment<br />

<strong>in</strong>come <strong>and</strong> awareness of offences, penalties <strong>and</strong> f<strong>in</strong>es tend to be more compliant.<br />
