Types of Taxes in the U.S.

The U.S. tax system is multifaceted, with a variety of taxes levied by federal, state, and local governments. The key types of taxes include:

1. Income Tax

Income tax is levied on earnings from employment, business activities, and investments. The Internal Revenue Service (IRS) is responsible for administering federal income taxes, while most states and some localities also impose their own income taxes. The rates vary depending on the jurisdiction, and progressive tax rates are commonly used, meaning that individuals pay higher tax rates as their income increases.

Understanding Your Tax Obligations:

Some states do not impose income tax at all, while others have significantly higher tax rates.

The federal income tax system operates on a progressive scale, with tax rates increasing from 10% to 37% for the 2024 tax year.

2. Payroll Taxes

Payroll taxes are deducted directly from an employee’s wages to fund federal programs such as Social Security and Medicare. Employers also contribute a matching amount. These taxes are crucial for supporting retirement and healthcare programs for American workers.

Key Points:

• Social Security tax rate: 6.2% for employees and employers (up to a wage base limit). Learn more at the Social Security Administration (SSA).
• Medicare tax rate: 1.45% for employees and employers (with an additional 0.9% for higher-income earners).

3. Sales Tax

Sales tax is a state or local tax levied on the sale of goods and services. The rate varies widely depending on the jurisdiction.

Key Points:

• Some states like Delaware and Oregon have no sales tax, while others like Tennessee and Arkansas impose rates exceeding 9%. View the latest state-by-state sales tax rates.

4. Property Tax

Property taxes are levied on real estate and, in some states, personal property such as vehicles. These taxes are a primary source of revenue for local public services.

Key Points:

• Property tax rates vary by locality and are generally based on the assessed value of the property.
• Check your state’s property tax rates on the National Association of Counties.

5. Corporate Tax

Corporate taxes are imposed on business profits. The federal corporate tax rate is 21%, but state corporate tax rates vary widely.

Key Points:

• Learn more about corporate tax obligations at the IRS Business Section.

6. Excise Taxes

How the Federal Income Tax System Works

The federal income tax system in the U.S. is progressive, meaning that individuals with higher incomes pay a higher percentage of their income in taxes. Understanding the federal tax brackets is crucial for calculating your tax liability. Here’s an overview of the 2024 federal tax brackets for single filers:

Income Bracket (USD)	Tax Rate
$0 – $11,000	10%
$11,001 – $44,725	12%
$44,726 – $95,375	22%
$95,376 – $182,100	24%
$182,101 – $231,250	32%
$231,251 – $578,125	35%
Over $578,125	37%

For example, if you earn $50,000 annually as a single filer, your tax liability would be calculated as follows:

• 10% on the first $11,000 = $1,100
• 12% on the next $33,725 = $4,047
• 22% on the remaining $5,275 = $1,160.50

Total Tax: $6,307.50

Deductions and Credits

• Standard Deduction: For 2024, the standard deduction is $13,850 for single filers and $27,700 for married couples filing jointly.
• Itemized Deductions: Taxpayers can opt for itemized deductions instead of the standard deduction, including deductions for mortgage interest, state and local taxes (SALT), and medical expenses.
• Tax Credits: Tax credits reduce your tax liability directly. Notable credits include the Child Tax Credit and the Earned Income Tax Credit.
