+# Tax on Luxuries
+
+## Definition
+
+A tax imposed on goods that are not essential for life and whose consumption
+is optional, which falls directly on the consumers of these goods without
+affecting the wages of labour or the prices of other commodities.
+
+## Source Chapter
+
+Book V, Chapter 2
+
+## Context
+
+Smith considers taxes on luxuries to be more equitable than taxes on necessaries
+because they are paid voluntarily by those who choose to consume such goods,
+and they do not have the broader economic effects of raising wages or prices.
