1. What is Casualty Loss Deduction?

The casualty loss deduction allows taxpayers to deduct certain losses from sudden, unexpected, or unusual events like natural disasters, accidents, or theft. The deductible amount is calculated after accounting for insurance reimbursements and IRS thresholds.

2. How Does the Calculator Work?

The calculator uses the IRS casualty loss formula:

Where:

• \( Loss \) — Total amount of the casualty loss
• \( Insurance \) — Insurance reimbursement received
• \( AGI \) — Your adjusted gross income
• \( 100 \) — IRS per-event deductible
• \( 0.1 \times AGI \) — 10% of AGI threshold

Explanation: The deduction is the loss amount minus any insurance reimbursement, minus $100 per event, minus 10% of your AGI. The result cannot be negative.

3. Importance of Casualty Loss Calculation

Details: Properly calculating casualty losses can significantly reduce taxable income after disasters or accidents. This deduction is particularly important for major uninsured losses.

4. Using the Calculator

Tips: Enter the total loss amount, any insurance reimbursement received, and your AGI. All values must be non-negative dollar amounts.
