Every year, millions of people in the United States check their paychecks and wonder why they're receiving less money than they expected. Part of the answer lies in income tax, one of the pillars of the country's tax system. Understanding how it works and where it applies can make a big difference when planning your personal finances and choosing where to live. Income tax is a levy that governments apply to income generated by individuals and businesses within their territory. In the United States, it exists at both the federal and state levels. This means that, in most cases, taxpayers must file two tax returns each year: one to the federal government and one to their state of residence. The purpose of this tax is to fund public services and government obligations. The revenue collected helps support programs such as Social Security, public education, road infrastructure, and other essential services. Simply put, it is one of the main ways citizens contribute to the functioning of the country. There are different types of income tax. The most common is personal income tax, which applies to wages, salaries, tips, commissions, and other income earned by an individual. Depending on individual circumstances, it's possible to reduce the amount owed through deductions, exemptions, or tax credits. These benefits can make a portion of income untaxable. There's also corporate income tax. This applies to corporations, small businesses, and the self-employed. In this case, businesses report their income and subtract operating expenses, capital investments, and other allowable deductions. The resulting amount is taxable income, on which taxes are calculated. One of the most frequent questions is what percentage of income is taxed. There isn't a single figure. The rate depends on how much a person earns and their tax status.The U.S. tax system is progressive. This means that the higher your income, the higher the percentage you pay. For this reason, two people with different salaries do not contribute the same amount. Calculating income tax involves several steps. First, all sources of taxable income earned during the tax year are added together. Then, adjusted gross income is determined. From there, applicable deductions, such as the standard deduction or itemized deductions, are subtracted. The final result is taxable income, on which the corresponding tax rates are applied. A key aspect for many Latino families is knowing that not all states levy income tax.

It does not tax wages or employment income. However, it does levy a 5% tax on income from interest and dividends. This is relevant for those with significant investments or savings.
