In economic terms, the Incidence of Tax refers to the final allocation of the tax burden between buyers and sellers. It determines who ultimately pays for or bears the economic burden of the tax. For example, in the case of tobacco taxes, smokers end up bearing the incidence through increased prices.
Types of Tax Incidence
Legal Incidence
The legal incidence of tax falls on the party that is legally bound to pay the tax to the government. For example, the legal incidence of excise taxes on tobacco falls on the tobacco manufacturers who are required to pay the tax.
Economic Incidence
The economic incidence focuses on the effective burden of the tax, regardless of who is legally responsible for the payment. For instance, if the tobacco manufacturers pass the cost of the excise tax to smokers by raising prices, the economic incidence falls on the smokers.
Factors Affecting Tax Incidence
Elasticity of Demand and Supply
- Elasticity of Demand: If the demand for a product is inelastic (i.e., consumers are not sensitive to price changes), a greater portion of the tax burden can be shifted to consumers.
- Elasticity of Supply: Similarly, if the supply of a product is inelastic, producers may absorb a higher share of the tax burden.
Market Structure
Competitive markets versus monopolistic markets can also impact how the tax burden is distributed.
Example: Tobacco Tax
When a tobacco tax is levied, the legal incidence falls on tobacco producers. However, they can pass part or all of this tax onto consumers in the form of higher prices. The final distribution of the tax burden between producers and consumers depends on the price elasticity of demand and supply.
Historical Context
The concept of tax incidence has been a crucial part of economic theory since the works of Adam Smith and David Ricardo. Their early analysis laid the groundwork for understanding how tax policies affect different economic agents.
Applicability in Public Finance
Understanding tax incidence helps policymakers design equitable tax systems and avoid unintended consequences. For example, taxing a good with inelastic demand ensures higher revenue with less behavioral change among consumers.
Comparisons
Direct Taxes vs. Indirect Taxes
- Direct Taxes: Taxes directly levied on income, wealth (e.g., income tax).
- Indirect Taxes: Taxes levied on goods and services (e.g., sales tax), with the incidence shifting among different market participants.
Related Terms
- Tax Shifting: The process by which the initial economic burden of a tax is transferred from the entity legally responsible for the tax to another party.
- Deadweight Loss: A loss of economic efficiency that occurs when the equilibrium for a good or service is not achievable due to taxation.
- Subsidy Incidence: The counterpart of tax incidence, focusing on who benefits from government subsidies.

Summary
The incidence of tax is a pivotal concept in understanding the distributional effects of taxation policies. It distinguishes between the legal responsibility to pay a tax and the actual economic burden experienced by market participants. By analyzing factors like elasticity and market structures, policymakers can better predict and manage the impacts of taxes to achieve economic equity and efficiency.
