Quick Answer
Yes, you can deduct casualty losses from federally declared disasters above $100 per incident plus 10% of AGI. For a $75,000 income earner with $25,000 in uninsured hurricane damage, this creates a $17,400 deduction worth ~$3,800 in tax savings.

Homeowners who suffered property damage from hurricanes, wildfires, floods, or other natural disasters
What qualifies as a deductible casualty loss?
According to IRS Publication 547, a casualty loss must be sudden, unexpected, and result from a federally declared disaster area. This includes hurricanes, tornadoes, wildfires, floods, earthquakes, and severe storms — but not gradual damage like termites or normal wear and tear.
The calculation formula
Your deductible casualty loss equals:
[Total Loss] - [Insurance Reimbursements] - $100 - [10% of AGI]
Step-by-step example: Hurricane damage
Homeowner profile:
Calculation:
1. Actual loss: $50,000
2. Less: Insurance received: -$25,000
3. Net loss: $25,000
4. Less: $100 per casualty: -$100
5. Less: 10% of AGI ($7,500): -$7,500
6. Deductible casualty loss: $17,400

Retired individuals living on Social Security, pensions, and retirement account distributions who may have lower AGI thresholds
How lower AGI helps retirees with casualty losses
Retirees often benefit more from casualty loss deductions because their lower Adjusted Gross Income means a smaller 10% threshold to overcome. This makes casualty losses more accessible for seniors on fixed incomes.

Special considerations for retirees
Timing elections: Retirees may benefit from claiming losses in the prior year if they had higher income (and thus higher tax brackets) before retirement.
Itemizing vs. standard deduction: The 2026 standard deduction is $15,000 (single) or $30,000 (married). Casualty losses might push you over the itemizing threshold.
State tax benefits: Many states don't have the federal AGI limitation, providing additional savings.
Key takeaway: Retirees' lower AGI makes casualty loss deductions more accessible, as the 10% threshold is easier to exceed with typical disaster-related losses.
Key Takeaway: Retirees benefit from lower 10% AGI thresholds for casualty losses, making disaster deductions more accessible on fixed retirement incomes.
