Final answer:
Arturo can include $8,070 of medical expenses and $9,684 of the casualty loss in his itemized deductions for 2020, subtracting expected insurance reimbursements from his total expenses and losses.
Step-by-step explanation:
Before considering any limitations on deductions, Arturo can include $8,070 of the medical expenses and $9,684 of the casualty loss when determining his itemized deductions for 2020. This is calculated by subtracting the expected insurance reimbursements from the total expenses and losses incurred. Specifically, for medical expenses: $26,900 - $18,830 = $8,070, and for the casualty loss: $32,280 - $22,596 = $9,684.
An itemized deduction is an expense that can be subtracted from your adjusted gross income (AGI) to reduce your tax bill. Taxpayers can itemize deductions or claim the standard deduction that applies to their filing status. Itemized deductions must be listed on Schedule A of Form 1040 and may include mortgage interest, charitable gifts, and unreimbursed medical expenses.
Itemized deductions reduce your taxable income, and your savings depends on your tax bracket. Suppose an unmarried single filer with a gross income of $80,000 claims itemized deductions totaling $15,000. Subtracting those deductions from gross income yields a taxable income of $65,000, which falls within a 22% marginal tax rate bracket for 2023 and 2024.
