Tax shifting refers to the process where the economic burden of a tax is transferred from the entity that is statutorily liable to another party. This phenomenon occurs through various mechanisms such as changes in market prices or wages.
Mechanisms of Tax Shifting
Price Adjustments
One common mechanism for tax shifting is through price adjustments. If a business faces a new tax, it may raise the prices of its goods or services to cover the additional cost, thereby shifting the tax burden to consumers.
Example:
If a government imposes a $1 tax on each unit of a product, the business might increase the product price by $1. Thus, the consumer effectively bears the tax burden.
Wage Adjustments
Similarly, tax shifting can occur via changes in wages. If employers are subjected to payroll taxes, they might reduce wages or delay wage increases to compensate for the additional tax expense.
Example:
A firm facing a higher payroll tax might reduce employee wages by an equivalent amount, shifting the tax burden onto its workers.
Types of Tax Shifting
Forward Shifting
This occurs when the tax burden is transferred from producers to consumers. Forward shifting typically happens through price increases.
Example:
A sales tax on gasoline results in higher prices at the pump, meaning consumers bear the cost.
Backward Shifting
In backward shifting, the tax burden is transferred from producers to suppliers. This can occur when businesses negotiate lower raw material prices to offset the tax.
Example:
A tax on final goods may lead producers to demand lower prices from their suppliers.
Factors Affecting Tax Shifting
Elasticity of Demand and Supply
The elasticity of both demand and supply significantly impacts tax shifting. Products with inelastic demand (necessities) are more likely to see forward shifting, as consumers are less sensitive to price changes.
Market Structure
Market structure, such as monopolies or competitive markets, also affects the ability to shift taxes. Businesses in monopolistic markets are often better positioned to pass the tax burden to consumers.
Historical Context
Tax shifting has been a critical consideration in public finance since the classical economics era. Concepts introduced by economists like Adam Smith and David Ricardo include foundational discussions on tax incidence (who ultimately pays the tax).
Comparisons and Related Terms
Tax Incidence
Tax incidence closely relates to tax shifting but focuses more on who ultimately bears the burden of a tax—be it consumers, producers, or others.
Deadweight Loss
This term refers to the loss of economic efficiency when the equilibrium outcome is not achievable due to taxation. Deadweight loss can result from tax shifting by altering consumption and production patterns.

Summary
Tax shifting remains a pivotal concept in understanding the broader economic impact of taxation policies. By examining mechanisms like price and wage adjustments, as well as factors influencing tax shifting such as elasticity and market structure, policymakers and economists can better predict the real-world implications of tax legislation.
