Explanation:

The point where tax makes its effect felt is known as the impact of tax—the after effect of tax imposition.

The tax which has incidence and impact at the different points is the indirect tax—the person who is hit does not bleed’ someone else bleeds. As, for example, excise, sales tax, etc., which are imposed on either the producers or the traders, but it is the general consumers who bear the burden of tax. The tax which has incidence and impact both at the same point is the direct tax—the person who is hit, the same person bleeds. As for example income tax, interest tax, etc.
