# Local Income Taxes | Principles of Economics

## Definition

Local income taxes are taxes that city or county governments charge on income earned within their jurisdiction. In Principles of Economics, they are a local revenue source that changes the total tax burden and can affect where people work or live.

## What It Is

Local income taxes are taxes imposed by a city, county, or other local government on income earned by people or businesses in that area. In Principles of Economics, they are one way local governments raise revenue without depending only on property taxes, sales taxes, or state aid.

These taxes are usually set as a percentage of income, often at a flat rate. That means everyone subject to the tax pays the same rate, even though the dollar amount paid rises with income. So if the rate is 1 percent, a person earning more pays more in taxes, but not at a higher rate than someone earning less.

Local income taxes matter because local governments use them to pay for services tied to the community, such as public schools, police and fire protection, roads, transit, and utilities. The exact services supported depend on the local budget, but the basic idea is the same: the tax helps fund things people in that area use.

A big economics question is who actually bears the burden. Even if a local income tax is legally paid by workers or firms, part of the burden can be shifted through lower wages, higher prices, or changes in where people choose to work and live. That is why economists look at both the legal incidence and the economic incidence of the tax.

Local income taxes also create differences across places. Some cities and counties have them, while others do not. That can make the total tax burden very different from one community to another, which can affect migration, business location decisions, and local housing demand.

In practice, you might see a local income tax appear alongside state and federal income taxes on a paycheck or tax form. It is not a separate kind of income in economics, it is a local claim on earned income that helps local governments finance public goods and services.

## Why It Matters

Local income taxes show how government revenue choices affect incentives, fairness, and public service funding. In Principles of Economics, this term sits right inside tax analysis, where you compare who pays, how much they pay, and what changes when the tax exists.

It also helps you think about tax structure. A local income tax is often flat, so it is usually proportional at the local level, but the total tax burden can still feel different across income groups once you combine it with state, federal, sales, and property taxes. That is a common place where students mix up legal rate with actual burden.

This term also connects to local public finance. Cities and counties have to fund services somehow, and local income taxes are one option among property taxes, sales taxes, fees, and state transfers. If a question asks why one town can offer better services than another, local tax revenue is part of the answer.

Finally, local income taxes are useful for policy analysis. You can use them to explain why people might shop, work, or move across municipal borders, especially when neighboring places tax income differently. That makes the term useful for any question about location decisions and the economic effects of taxation.

## Connections

### Flat Tax

Local income taxes are often flat, meaning the rate stays the same no matter how much income someone earns. That makes them different from progressive systems where the rate rises with income. If a problem asks whether a local tax is proportional or progressive, look at the rate structure, not just the dollar amount paid.

### [Proportional Taxes](/principles-econ/key-terms/proportional-taxes)

Many local income taxes are proportional because the tax rate is constant across income levels. Someone earning twice as much usually pays twice as much in tax if the rate is flat. This connection helps you judge fairness arguments, since the tax does not take a larger percentage from higher incomes.

### Tax Deduction

A tax deduction lowers taxable income, which can reduce how much federal tax someone owes after paying certain state or local taxes. This matters because the size of a local income tax is not always the same as its final cost. When deductions apply, the effective burden can be smaller than the sticker price.

### [Property Taxes](/principles-econ/key-terms/property-taxes)

Local governments often rely on property taxes instead of, or alongside, local income taxes. Property taxes are tied to real estate value, while local income taxes are tied to earnings. Comparing them helps you explain why different towns choose different revenue sources and how those choices spread the tax burden.

## On the AP Exam

A quiz question or short response may ask you to identify what a local income tax is funding, or to compare it with another tax system. You might need to tell whether the tax is flat, proportional, or regressive in effect, and explain why the legal rate is not always the same as the economic burden.

In a problem set, you could be given two cities with different local tax rates and asked how that affects take-home pay, business location, or public service funding. In a case question, look for clues like a city payroll tax, a county income surcharge, or a paycheck deduction tied to where someone works. The main move is to connect the tax to local revenue and to any behavioral change it may cause.

## Local Income Taxes vs Property Taxes

Local income taxes and property taxes both fund local government, but they tax different bases. Local income taxes are based on earnings, while property taxes are based on the value of land and buildings. They can affect households differently, so a question may ask you to compare which one places more burden on workers, homeowners, or local businesses.

## Key Takeaways

- Local income taxes are taxes charged by a city, county, or similar local government on income earned in that area.
- They are often flat-rate taxes, so the percentage stays the same even as the dollar amount rises with income.
- The money usually supports local public services like schools, safety, roads, and utilities.
- Economists care about both the legal payer and the real burden, because taxes can change wages, prices, and location choices.
- Local income taxes are one part of a larger tax system that may also include property taxes, sales taxes, and state or federal income taxes.

## FAQs

### What is local income tax in Principles of Economics?

Local income tax is a tax a city, county, or other local government charges on income earned within its area. In economics, it is one way local governments raise revenue for services such as schools, roads, and public safety. It also matters because it can change how much people keep from their paychecks and where they choose to live or work.

### Is a local income tax flat or progressive?

It is often flat, meaning the rate stays the same for all income levels within that jurisdiction. That makes the tax proportional in structure, even though higher earners still pay more dollars. If a question asks about progressivity, check whether the rate changes with income or stays constant.

### How is local income tax different from property tax?

Local income tax is based on earnings, while property tax is based on the value of property such as land and buildings. Both fund local government, but they fall on different groups and can influence behavior differently. Property taxes affect homeowners more directly, while income taxes affect workers and sometimes businesses.

### Why do local governments use income taxes?

Local governments use income taxes to bring in revenue for public services without relying only on property taxes or sales taxes. They can spread the burden across people who earn income in the area, including commuters in some places. In economics, this also raises questions about fairness, tax burden, and whether people change behavior to avoid the tax.
