Itemized deductions are when you list your tax expenses instead of taking the federal standard deduction. 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.
Common itemized expenses include are:
The mortgage interest you pay on up to two homes,
Your state and local income or sales taxes,
Property taxes,
Medical and dental expenses that exceed 7.5 percent of your adjusted gross income,
The charitable donations you make.
Also miscellaneous deductions such as work-related travel and union dues.
