What is income tax from each paycheck?

Income tax from each paycheck is the portion of an employee's earnings that is withheld by the employer to pay federal, state, and sometimes local taxes. This withholding is typically calculated based on the employee's income level and filing status, using a tax table or withholding formula provided by the IRS. The withheld amount is then sent to the government on behalf of the employee, ultimately contributing to their annual tax liability. The amount can vary from paycheck to paycheck depending on changes in income, deductions, or tax credits.
