You pay taxes based on your income. But before that income is calculated, the IRS allows you to reduce it based on exemptions. What is a tax exemption? A standard amount of money (defined each year by the IRS) that is not taxed. For tax year 2014, the personal exemption amount is $3,950. That means that for each person claimed on your taxes (which may include yourself, your spouse, and qualifying dependents ), your taxable income will be reduced by $3,950.
Rules for Tax Exemptions
In order to claim a tax exemption you must earn income and file a tax return . In addition, nobody else may claim you as a dependent. If you are in college and file your own return, but your parents still claim you as a dependent, you cannot use your own exemption. You may claim an exemption for your spouse only if your filing status  is married filing a joint return or if you are filing a separate return and your spouse does not need to file a return .
Note that exemptions are different than deductions .
