Lower tax rates in the agricultural sector are often indicated as an example of policies that benefit low-income individuals. In this paper, I use a computable general equilibrium model to evaluate the impact of such policy in Brazil. It is found, first, that the policy would tend to enhance the landowners’ rents, thereby reinforcing the country’s income concentration. Nonetheless, because of the changes in the economy’s relative prices due to the policy, in particular the lowering of the agricultural goods’ prices, the 10% of the population with lowest income would be indeed the group benefiting the most from it. This would occur because that group is, in proportion to its own income, the main consumer group of agricultural goods. It is also found, however, that the policy would cause a non-negligible reduction of the tax revenue collected by the government.
