When you get your paycheck, you might notice that the amount you take home is less than what you actually earned, and that's because some money is withheld. Typically, this includes taxes like federal and state income tax, as well as other deductions like social security and Medicare taxes. You might also see deductions for health insurance, retirement plans, or other benefits. To check these deductions, you can look at your pay stub, which should break down all the withholdings and deductions. You can also talk to your HR department or payroll person to get a better understanding of what's being withheld and why.
