a.) An itemized deduction is a specific expense that taxpayers can deduct from their total income when calculating their taxable income. These deductions are detailed and listed individually on a taxpayer's return, rather than taking the standard deduction, which is a fixed dollar amount. Common examples of itemized deductions include mortgage interest, state and local taxes, charitable contributions, medical expenses (above a certain threshold), and certain unreimbursed business expenses. Taxpayers generally use Schedule A of IRS Form 1040 to report their itemized deductions.
b.) You should choose to itemize deductions instead of using the standard deduction if the total of your itemized deductions exceeds the amount of the standard deduction for your filing status. For many taxpayers, especially those with significant mortgage interest, high medical expenses, or large charitable contributions, itemizing might result in a lower taxable income and a lower tax bill. Here are a few situations where itemizing may be beneficial:
-
High Medical Expenses: If your unreimbursed medical expenses exceed 7.5% of your adjusted gross income (AGI), you can deduct the amount that exceeds that threshold.
-
Mortgage Interest: If you pay significant interest on a mortgage for your primary residence or a second home, this can lead to a large itemized deduction.
-
State and Local Taxes (SALT): If you pay substantial state and local taxes (up to a limit of $10,000 for single and married filing jointly), this could also encourage itemizing.
-
Charitable Contributions: If you make substantial charitable donations, itemizing may allow you to deduct those contributions.
-
Miscellaneous Deductions: Some unreimbursed expenses related to your job or other qualified expenses could also add to your itemized deductions.
Taxpayers should carefully calculate both options to determine which method offers a greater tax benefit.
