+# Tax on Necessaries
+
+## Definition
+
+A tax imposed on goods that are essential for life or considered necessary
+by social custom, which raises the price of these goods and consequently the
+wages of labour, ultimately falling on landlords through reduced rent and
+on consumers through higher prices.
+
+## Source Chapter
+
+Book V, Chapter 2
+
+## Context
+
+Smith argues that taxes on necessaries are particularly burdensome because
+they affect the poor most heavily and raise the cost of production throughout
+the economy, making them less desirable than taxes on luxuries.
