Governments often include equity considerations when determining rates for
value added taxes (VAT). This paper explores the implication of current and
proposed tax exemptions in South Africa from the perspective of their impa
cts on the expenditures of the poor and on the calorie and protein consumpt
ion of low-income households. Maize, which is currently exempted from VAT,
is shown to be the best choice for low fax rates from both the standpoints
of equity and the impact on the food consumption of the poor. In contrast,
lower tax rates on fluid milk, which is currently exempted from VAT, and me
at, for which an exemption has been proposed, are not good vehicles for ass
isting the poor. The paper illustrates the revenue forgone with zero tax ra
tes on these commodities and compares the tax relief for the poor and chang
e in nutrients consumed from alternative tax exemptions.
