Unlike the federal government, states can't print money to pay their bills. Instead, they rely on taxes to fund everything from roads and schools to state parks and police forces. Each state develops its own unique mix of taxes to generate the revenue it needs.

While every state's tax code is a little different, most rely on a few common types of taxes. The three heavy hitters are income, sales, and property taxes. Let's break them down.

If you earn a paycheck, you're likely familiar with income tax. Many states tax a portion of the money earned by individuals and corporations within their borders. Some states use a progressive system, where higher earners pay a larger percentage of their income in taxes. Others use a flat tax, where everyone pays the same rate regardless of income. A handful of states have no personal income tax at all.

Next up is the sales tax, which you pay almost every time you buy something.

Sales tax is a type of consumption tax, meaning you pay it when you spend money. States set a base sales tax rate, and sometimes cities or counties can add their own local sales tax on top. Not everything is taxed, though. States often exempt necessities like groceries or prescription drugs to lessen the burden on lower-income households.

Finally, there's property tax, which is a primary source of funding for local governments.

While property taxes are usually collected at the local level (think counties and cities), the rules governing them are set by the state. This tax is based on the assessed value of property, primarily real estate. The revenue is crucial for funding local public schools, fire departments, and other community services.

Beyond the big three, states collect revenue through several other taxes that target specific goods or activities. One of the most common is the excise tax.

Excise taxes are built into the price of certain products. Think of the state taxes on gasoline that help pay for road maintenance, or the taxes on cigarettes and alcohol, sometimes called "sin taxes," which can be used to fund public health programs. Other examples include taxes on hotel rooms and rental cars.

States also levy corporate taxes on business profits and estate taxes on assets transferred after someone's death. Each of these taxes plays a part in the state's overall financial picture.

So, where does all this money go? State tax revenue is the lifeblood of public services. It pays for K-12 education, state university systems, healthcare programs like Medicaid, and the construction and maintenance of infrastructure like highways and bridges. It also funds state police, court systems, and prisons.

When designing their tax systems, states often try to balance several competing goals. They want a system that is equitable, or fair, ensuring that the tax burden is distributed appropriately across the population. They also aim for efficiency, meaning the tax should raise revenue without discouraging economic activity. Finally, a tax system should be adequate, generating enough money to consistently fund public services.

Now that you have a general understanding of how state taxes work, let's review some key terms.
