When theft and casualty losses are deductible
Theft and casualty losses can be deductible, but only if they meet strict IRS requirements and exceed high thresholds. According to IRS Publication 547, you can deduct personal casualty and theft losses only if:
1. The loss exceeds $100 per incident
2. Your total losses exceed 10% of your adjusted gross income (AGI)
3. You itemize deductions instead of taking the standard deduction
4. The loss isn't covered by insurance
Example: $80,000 homeowner with $15,000 theft loss
Let's say you earn $80,000 AGI and thieves steal $15,000 worth of jewelry and electronics from your home. Your insurance covers $8,000, leaving you with a $7,000 uninsured loss.
Calculation:
Your loss doesn't exceed the 10% AGI threshold ($8,000), so you get no deduction.
Higher loss scenario:
If the uninsured loss was $12,000:

Best for W-2 employees with standard deductions who experienced minor theft or casualty losses
Why most small losses don't qualify
If you're a typical W-2 employee taking the standard deduction ($15,000 single, $30,000 married filing jointly in 2026), casualty and theft losses rarely provide tax benefits due to the high thresholds.
Example: $50,000 earner with car break-in
Your car window is smashed and $2,000 of items are stolen. Insurance covers $500, leaving you with $1,500 out-of-pocket.
Calculation:
The 10% AGI threshold ($5,000) is higher than your loss, so you get no tax benefit.
When it might still be worth documenting
Alternative options for smaller losses
Key takeaway: For most people with typical incomes and smaller losses, the 10% AGI threshold makes casualty and theft deductions unavailable.
Key Takeaway: Most smaller theft and casualty losses don't qualify for deductions due to the high 10% AGI threshold requirement.

Best for families who experienced significant losses from natural disasters or major theft events
Special considerations for families
Families often have higher dollar amounts at risk (home contents, multiple vehicles, children's belongings) and may be more likely to exceed the 10% AGI threshold for casualty loss deductions.
Example: Family of four with $70,000 AGI and flood damage
Your home floods, causing $20,000 in damage to furniture, appliances, and personal belongings. Insurance covers $12,000, leaving $8,000 uninsured.
Calculation:

Documentation tips for families
Key takeaway: Families with substantial property and possessions are more likely to exceed the 10% AGI threshold, making casualty loss deductions potentially valuable after major events.
Key Takeaway: Families with more property at risk are more likely to benefit from casualty loss deductions when major disasters strike.
