Which option is typically not considered an itemized deduction on federal taxes?

The correct answer is C, Traditional IRA contributions, because these contributions are not considered itemized deductions; instead, they may be deductible as an adjustment to income on your tax return. This means that when you make contributions to a Traditional IRA, you often can deduct these amounts directly from your gross income, which directly reduces your taxable income for the year.

On the other hand, medical expenses, charitable contributions, and home mortgage interest are all examples of itemized deductions. They require taxpayers to itemize their deductions on Schedule A of their tax returns rather than using the standard deduction. This means that taxpayers need to have qualifying expenses that exceed the standard deduction threshold to benefit from these deductions. Each of these itemized deductions has specific criteria and limitations, but they are intended to reduce taxable income based on actual expenses incurred during the tax year.
