The federal Standard Deduction is a fixed dollar amount, based on your filing status and age, that the IRS lets you take off (deduct) from your taxable income.
On the other hand, itemizing deductions allows you to list (itemize) your deductions on Schedule A.
The IRS lets you either choose the "bundled" Standard Deduction or go "a la carte" and itemize your deductions. Naturally, most taxpayers want the one that gives them the most money back.
