Income Tax
What Is Income Tax?
Income tax is a tax governments impose on the money individuals and businesses earn. In the United States, income taxes are collected by the federal government and often by state and local governments as well.
Income tax applies to many types of earnings, including wages, salaries, self-employment income, investment income, and certain retirement withdrawals.
Why Income Tax Matters
Income tax directly affects how much of your earnings you keep. It influences your take-home pay, financial planning decisions, and eligibility for deductions and tax credits.
Understanding income tax helps you estimate what you owe and identify opportunities to legally reduce your tax burden through deductions, credits, and tax-advantaged accounts.
How Income Tax Works
Income tax in the U.S. is based on a progressive system, meaning higher portions of income are taxed at higher rates.
The general process includes:
- calculating total income
- subtracting adjustments and deductions
- determining taxable income
- applying tax rates based on tax brackets
Employers typically withhold estimated income taxes from paychecks throughout the year.
Example
If you earn $70,000 from your job, deductions such as the standard deduction reduce the portion of income that is taxed. The remaining amount becomes your taxable income, and the IRS applies tax rates based on your tax bracket.
Income Tax vs Payroll Tax
- Income tax funds general government operations.
- Payroll taxes specifically fund programs such as Social Security and Medicare.
