Tax Incidence

Tax incidence tells us who really bears the burden of a tax — regardless of who writes the cheque to the government. A tax creates a wedge between the price buyers pay () and the price sellers receive (). The tax . Even when the tax is legally imposed on sellers, part of the burden lands on buyers through a higher price.

Key Term

Tax Incidence and Elasticity

The burden of a tax falls more heavily on the less elastic side of the market. If demand is less elastic than supply, buyers bear more of the tax. If supply is less elastic than demand, sellers bear more. This holds regardless of whether the tax is legally placed on buyers or sellers.

The ratio of the tax burden on buyers vs. sellers equals the ratio of supply elasticity to demand elasticity

It doesn’t matter who the tax is legally imposed on. Whether you tax producers or consumers, the economic outcome is identical. The market adjusts so the burden splits according to relative elasticities. The more inelastic side can’t escape the tax (they’re less responsive to price changes), so they bear more of the burden.

Worked Example

Demand: . Supply: . A 10 dollars per-unit tax is imposed. Find the new prices paid by buyers and received by sellers.

Same E* and same 10 dollar tax in all three scenarios. Only the demand slope (elasticity) changes — and the burden split flips with it.
