Introduction

Taxes are the financial foundation of modern governance, funding everything from national defense to local road repair. In the United States, the tax system is layered across federal, state, and local governments, each with distinct revenue sources and spending responsibilities. For citizens and businesses alike, understanding who collects which taxes—and how those dollars are deployed—is essential for navigating personal finances, evaluating public policy, and holding governments accountable. This article provides a detailed breakdown of the taxes levied at each government level, how they work, and what they fund.

Federal Taxes

The federal government collects the largest share of tax revenue in the United States, primarily through income and payroll taxes. These funds support nationwide programs such as national defense, Social Security, Medicare, and federal infrastructure. Below are the major federal tax types and how they function.

Individual Income Tax

The individual income tax is the single largest source of federal revenue. It is a progressive tax—meaning tax rates increase as income rises. For the 2024 tax year, rates range from 10% to 37%, applied to taxable income after deductions and exemptions. The Internal Revenue Service (IRS) administers collection, and most workers have taxes withheld from their paychecks. Taxpayers must file annual returns to reconcile withheld amounts with their actual tax liability. This tax funds a broad array of federal programs, including defense, healthcare, and education.

Payroll Taxes

Payroll taxes are dedicated to funding Social Security and Medicare. The Federal Insurance Contributions Act (FICA) tax is 15.3%—12.4% for Social Security (capped at a wage base of $168,600 in 2024) and 2.9% for Medicare (no cap). Employers and employees each pay half (7.65%), though self-employed individuals pay the full amount. These taxes are critical for providing retirement benefits, disability insurance, and hospital insurance for eligible Americans.

Corporate Income Tax

Corporations pay a flat 21% federal tax on their profits, set by the Tax Cuts and Jobs Act of 2017. This revenue comes from the net income of C-corporations, while S-corporations and pass-through entities pass income to owners taxed at individual rates. The corporate tax is a smaller share of federal revenue compared to individual income and payroll taxes, but it remains a significant source—especially for regulating business behavior and funding general government operations.

Excise Taxes

Federal excise taxes are imposed on specific goods, services, and activities. Common examples include taxes on gasoline (18.4 cents per gallon), diesel (24.4 cents), tobacco, alcohol, and airline tickets. These taxes are often included in the purchase price and are collected by the IRS from manufacturers, importers, or retailers. Excise tax revenues often fund related trust funds—for example, the Highway Trust Fund uses fuel tax revenue to support road and transit infrastructure.

Estate and Gift Taxes

The federal estate tax applies to transfers of wealth after death, while the gift tax applies to lifetime transfers above a certain threshold. In 2024, the estate tax exemption is $13.61 million per individual, meaning only very large estates are subject to tax (rates up to 40%). Gift tax exemptions mirror the estate tax, with an annual exclusion of $18,000 per recipient. These taxes generate a small fraction of federal revenue but affect high-net-worth families and influence wealth transfer planning.

Other Federal Taxes

Additional sources include customs duties (tariffs) on imported goods, which are collected by the Customs and Border Protection agency and support general revenue. The federal government also imposes excise taxes on certain business activities, such as the Affordable Care Act’s net investment income tax (3.8% on investment income for high earners) and various environmental taxes.

State Taxes

State governments largely rely on income taxes, sales taxes, and corporate taxes to fund education, transportation, public health, and law enforcement. However, states vary widely in their tax structures—some have no income tax, while others have high rates. The following are the primary state-level taxes.

State Income Tax

As of 2024, 41 states and the District of Columbia impose a state income tax on residents’ wages and salaries. Eight states (Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no state income tax, while New Hampshire taxes only interest and dividends. Among states with income taxes, rates range from flat rates (e.g., Colorado at 4.4%) to progressive brackets (e.g., California with a top rate of 13.3%). These revenues help fund K-12 education, higher education, and social services.

Sales Tax

Forty-five states impose a statewide sales tax on goods and some services, with rates ranging from 2.9% (Colorado) to 7.25% (California). Five states (Alaska, Delaware, Montana, New Hampshire, Oregon) have no statewide sales tax, though local jurisdictions in Alaska may levy their own. Sales taxes are regressive because lower-income households spend a larger share of their income on taxable goods. States often exempt necessities like groceries, prescription drugs, and utilities to reduce the burden. Sales tax revenue is a primary source for state general funds, often directed toward education and health care.

State Corporate Income Tax

Most states tax corporate profits, with rates ranging from 2.5% (North Carolina) to 11.5% (New Jersey). Some states use flat rates, others progressive brackets. A growing trend is the adoption of “single-sales factor” apportionment, which only counts sales within the state when determining taxable income, reducing taxes for manufacturers. States also impose franchise taxes on the privilege of doing business, separate from income taxes.

Property Tax

While property taxes are primarily local, many states also play a role through state-level property taxes or programs like school funding equalization. For example, some states levy a small statewide property tax to support schools or set a uniform assessment ratio. However, the vast majority of property tax revenue goes to local governments—states simply set the legal framework for assessment and collection.

State Excise Taxes

Parallel to federal excise taxes, states impose their own excises on gasoline (average state gas tax is about 30 cents per gallon), alcohol, tobacco, cannabis (where legalized), and other products. These taxes are often dedicated to transportation funds, health programs, or general revenue. For instance, state cigarette taxes range from $0.17 per pack in Missouri to $4.35 in New York.

Local Taxes

Local governments—counties, cities, towns, school districts, and special districts—rely heavily on property taxes, local sales taxes, and other fees to provide essential services like police and fire protection, public schools, roads, parks, and sanitation. The mix varies enormously by jurisdiction.

Property Tax

Property tax is the backbone of local government finance. It is levied on real estate (land and buildings) based on assessed value, which is determined by county assessors. Effective rates (the actual tax paid as a percentage of home value) average about 0.99% nationally, but range from 0.31% in Hawaii to 2.23% in New Jersey. Revenue primarily funds local school districts (roughly half of property tax dollars), municipal services, and county operations. Tax rates are set by local elected bodies through complex budget processes, and many states impose caps on annual increases.

Local Sales Tax

In many states, local jurisdictions can add their own sales tax on top of the state rate. Combined local rates can push total sales tax above 10% in some cities (e.g., Chicago’s combined rate is 10.25%). Local sales taxes are collected by the state government and remitted back to the local government. The funds often support city streets, public safety, and economic development projects. As of 2024, roughly 10,000 local taxing jurisdictions in 38 states levy local sales taxes.

Local Income Tax

Some cities and counties impose a local income tax on residents and, in some cases, non-residents who work within the jurisdiction. Notable examples include New York City (up to 3.876%), Philadelphia (3.79% for residents, 3.44% for non-residents), and various cities in Ohio, Kentucky, and Maryland. These taxes are typically collected through employer withholding and help fund city services like streets, sanitation, and municipal pensions.

Utility Taxes and Fees

Many local governments tax utilities such as electricity, natural gas, water, and telephone services. These taxes may be a flat fee or a percentage of the bill. For example, many cities levy electric utility taxes of 1% to 10% on residential and commercial customers. The revenue goes into the general fund to support basic operations. Similarly, franchise fees are charged to utility companies for the right to use public rights-of-way, often passed through to consumers.

Business Licenses, Permits, and Fees

Local governments require businesses to obtain licenses and permits, charging fees that cover the cost of regulation and inspection. These fees vary by city and type of business, ranging from a few hundred dollars for a small service business to thousands for restaurants or construction firms. Revenue from these fees is used to fund zoning enforcement, health inspections, and business support services.

Other Local Revenue Sources

Some localities impose lodging taxes (hotel occupancy taxes), amusement taxes on tickets and admissions, and specific assessments on properties that benefit from improvements (e.g., streetlights, sidewalks). Special districts—such as fire districts, water districts, or library districts—can levy their own taxes or assess fees on property owners within the district. These are often authorized by voter approval.

Tax Distribution and Responsibilities

Each level of government has distinct spending responsibilities that determine how tax revenues are allocated. While there is overlap, the general division is as follows:

Federal Spending Priorities

The largest federal expenditures include Social Security (21% of spending), Medicare (14%), national defense (13%), health programs like Medicaid (10%), and net interest on the national debt (13%). Federal tax revenue is pooled into the general fund, but payroll taxes are legally dedicated to Social Security and Medicare trust funds. The federal government also provides grants to states and localities—for example, for highways, education, and disaster relief—which account for about 16% of federal spending.

State Spending Priorities

States spend the largest shares on K-12 education (roughly 35% of total state spending), higher education (10%), Medicaid (17%), transportation (8%), and public safety and corrections (5%). States also fund their own courts, parks, and environmental agencies. Sales and income taxes are the primary revenue sources, supplemented by federal grants. Many states rely on formula-based revenue sharing to distribute funds to local governments for education and other mandated programs.

Local Spending Priorities

Local governments spend heavily on primary and secondary education (through school districts—often the largest local government entity), police, fire, public works (roads, water, sewers), parks, libraries, and general administration. Property tax provides roughly 30% of local revenue, with state aid (including income and sales tax distributions) and federal grants making up the remainder. In many states, local governments are constrained by tax and expenditure limits that require voter approval for new taxes.

Intergovernmental Transfers and Tax Coordination

An important aspect of federalism is the flow of tax revenue between levels of government. The federal government provides grants to states and localities (e.g., for Medicaid, education, highways), often with matching requirements. States also transfer funds to local governments, especially for school funding and public health. This system aims to reduce disparities between wealthy and poor jurisdictions. However, it can create complexity—local governments sometimes face mandates from higher levels without full funding (unfunded mandates). Understanding these transfers is key to seeing the full picture of tax dollars.

The Impact of Taxes on Citizens and the Economy

The structure of taxation across levels affects economic behavior, equity, and public service quality. Here are key dimensions:

Economic Growth and Investment

Progressive income taxes can dampen incentives for additional work or investment at high incomes, while low corporate taxes may attract businesses. However, taxes on consumption (sales taxes) can reduce spending. The net effect depends on tax rates, exemptions, and what the revenue funds—investments in infrastructure, education, and health can boost long-term growth. The Tax Foundation regularly studies how state and local tax climates affect economic competitiveness.

Equity and Progressivity

The federal income tax is highly progressive, with the top 1% paying an average rate of about 26% while the bottom 50% pay negative or low rates due to credits. State income taxes vary in progressivity—some are flat, some have expanding brackets. Property taxes are generally regressive because lower-income homeowners spend a higher share of income on housing. Sales taxes are regressive unless exemptions for necessities are generous. Policymakers balance these effects through tax credits, deductions, and targeted spending programs.

Compliance and Administrative Costs

The three-tier tax system creates significant compliance burdens for small businesses and individuals, especially those operating across state lines. For example, remote sellers now must comply with local sales tax collection in thousands of jurisdictions following the South Dakota v. Wayfair Supreme Court decision. The IRS estimates that taxpayers spend about 6.5 billion hours annually on tax paperwork. States and localities also incur costs for collection and enforcement, which can be a significant fraction of revenue for small jurisdictions.

Public Service Quality

Reliance on property taxes can create large disparities in school funding—wealthy districts raise more money per student. Some states have enacted “Robin Hood” formulas that redistribute property tax revenue. Similarly, income tax-funded states can offer more robust social services. Citizens often judge tax fairness by the quality of public services received, which varies widely by location. Local governments with low property tax rates may struggle to maintain infrastructure, while high-tax jurisdictions can offer better services but may drive out residents.

Current debates touch on federal tax reform, state tax competition, and local revenue sustainability. Key trends include:

  • Federal tax reform: Discussions on extending the 2017 tax cuts, raising corporate rates, or implementing a wealth tax.
  • State tax competition: More states are cutting income tax rates to attract remote workers and businesses—for example, Florida and Texas benefit from no income tax.
  • Local revenue challenges: Declining property tax bases in urban cores and increased demand for services post-pandemic are pushing cities to consider local income taxes or sales taxes on services.
  • Digital taxation: States are expanding sales tax to digital goods and services, and there is growing pressure for federal clarity on taxing the digital economy.
  • Environmental taxes: Carbon taxes at the federal level or state-level carbon pricing are gaining traction as climate policy tools, though implementation remains limited.

Conclusion

Understanding the U.S. tax system’s multi-layered structure is vital for making informed decisions as a citizen, taxpayer, or business owner. The federal government collects the bulk of revenue through progressive income taxes and payroll taxes, funding national programs. States rely on a mix of income and consumption taxes to meet their responsibilities. Local governments lean heavily on property taxes to deliver essential community services. Each layer has unique trade-offs in terms of equity, economic impact, and administrative complexity. By recognizing who collects what and how those dollars are spent, individuals can better engage in policy debates and plan their financial futures.
