We study congestion pricing by a government that has redistributive concerns, in the presence of optimal income taxation. Individuals differ in (unobservable) earning ability and consumption technology for commodities using a congestible network (e.g. roads, Internet). We find, assuming separable preferences, that when efficiency of consumption technology is either invariant or postively correlated with earning ability, low ability individuals should face higher marginal congestion charges than high ability ones. Moreover, reducing congestion (by raising charges or expanding network capacity) enables government to increase redistribution. We also find that means tested congestion pricing may be necessary to implement the second-best allocation.
