There are five main categories of itemized expenses that you can deduct on your taxes:
1. Medical and dental expenses.
2. Taxes
3. Interest expenses.
4. Charitable contributions
5. Casualty and theft losses
Some itemized deductions are not allowed until they exceed a certain “floor” amount — medical expenses, miscellaneous deductions such as investment expenses, safe deposit fees, professional education, employee job-hunting expenses and tax-preparation fees.
