The Incidence of Tax refers to the distribution of the tax burden between buyers and sellers in a market. It essentially asks which party bears the economic burden of a tax - consumers or producers.
Economic Mechanism
Economically, the tax incidence can be depicted with the help of supply and demand curves. The actual burden is divided according to the price elasticity of both demand and supply.
When analyzing tax incidence:
- Price Elasticity of Demand: If demand is inelastic, consumers bear a greater share of the tax.
- Price Elasticity of Supply: If supply is inelastic, producers bear a greater share of the tax.
The formula \( \frac{dP}{dQ} = \frac{\text{Elasticity of Supply}}{\text{Elasticity of Supply} + \text{Elasticity of Demand}} \) is often used, where \( dP \) and \( dQ \) denote changes in price and quantity, respectively.
Types of Taxes and Their Incidence
Excise Tax
Applied to specific goods (e.g., cigarettes, alcohol):
- When demand is inelastic, consumers bear most of the tax.
- When demand is elastic, producers bear a larger part of the tax.
Sales Tax
A general tax on sales within a jurisdiction:
- Typically split between consumers and retailers based on their relative elasticities.
Income Tax
Levied on individual income:
- The incidence depends on labor supply and demand elasticities.
Special Considerations
Tax Shifting
- The process by which the economic burden of a tax is shifted from the entity legally responsible for payment to another party, usually because of changes in market prices.
Fiscal Incidence
- Fiscal incidence studies assess the overall impact of government taxation and expenditure policies on the distribution of income and wealth.
Historical Context
Tax incidence theory dates back to classical economics, with significant contributions from economists such as Adam Smith, David Ricardo, and later, Alfred Marshall. Over the centuries, understanding tax incidence has been crucial for effective tax policy formulation.
Examples
Example 1: Cigarette Tax
Consider a cigarette tax of $1 per pack:
- If the demand for cigarettes is highly inelastic, most of the tax burden falls on smokers (consumers).
- If the demand is elastic, cigarette producers and retailers absorb a larger portion of the tax.
Example 2: Luxury Tax
A luxury tax imposed on expensive cars:
- If supply is inelastic (limited production of luxury cars), producers bear most of the tax.
- If demand is price-sensitive (consumers can buy other luxury items), the tax incidence falls more on consumers.
Applicability
Understanding tax incidence is vital for policymakers to predict the outcomes of tax policies. By analyzing how a tax will affect different stakeholders, governments can design tax systems that minimize economic distortions and ensure fairness.
Comparisons
Tax Incidence vs. Tax Burden
- Tax Incidence explains how the tax burden is divided between consumers and producers.
- Tax Burden refers to the overall economic impact of a tax on taxpayers.
Direct vs. Indirect Taxes
- Direct Taxes (e.g., income tax): individuals directly bear the tax burden.
- Indirect Taxes (e.g., sales tax): the burden can shift between consumers and producers.
Related Terms

- Price Elasticity of Supply: Measure of responsiveness of quantity supplied to changes in price.

Summary
The Incidence of Tax explores who truly bears the economic burden of a tax—consumers, producers, or other entities. It relies heavily on the concepts of elasticities of demand and supply. Understanding tax incidence is crucial for the formulation of effective and fair taxation policies and can significantly influence economic behavior and market outcomes.
