Itemized Deductions

Itemized deductions allow taxpayers to reduce their taxable income based on specific personal expenses. If the total itemized deductions are greater than the standard deduction, it will result in a lower taxable income and lower tax.

In general, taxpayers benefit from itemizing deductions if they have mortgage interest, very large unreimbursed medical or dental expenses when compared to their income, or other large expenses such as charitable contributions. Itemized deductions will be covered in another lesson.
