Understanding Key Differences Between State and Federal Income Taxes

In countries with a federal governance system, authority is shared between the national government and individual states. Unlike most nations, the United States uniquely allows both levels to levy income taxes on citizens. Federal taxes fund national programs, while state taxes support local services such as education, healthcare, transportation, and infrastructure. The way these taxes are applied, the income types taxed, and the available deductions vary significantly between federal and state levels.

The federal government taxes income on a progressive scale, meaning higher earnings are taxed at higher rates. Conversely, many states adopt fixed or flat tax rates, taxing all residents equally regardless of income. Some states, including Alaska, Wyoming, Texas, Florida, South Dakota, Nevada, and Washington, do not impose income tax at all, relying instead on sales, property, and other levies.

Understanding Major Differences Between State and Federal Income Taxes

All individuals earning income in any state are required to pay federal taxes, including residents and non-residents. State taxes, however, are generally levied only on residents and are managed by state revenue departments. Income types taxed can differ; for example, federal income tax considers retirement income taxable, while some states offer exemptions. Interest on U.S. Savings Bonds is federally taxable but often exempt from state tax. Additionally, states like New Hampshire and Tennessee tax only interest and dividend income, not wages or pensions. Various states also offer tax credits—such as New York City’s credit for long-term care premiums—that are not available federally.

Staying informed about tax rules is essential. Follow updates on tax policies and benefits through trusted sources and social media channels to maximize your advantages and compliance.
