A disaster loss is a tax-deductible loss that occurs in federally declared disaster areas—think floods, forest fires, or earthquakes. Much like a casualty loss, it involves damage to property, but only if the President has declared the area a federal disaster zone.
💡 Disaster Loss Deductions
The IRS states, “Generally, you may deduct casualty and theft losses related to your home, household items, and vehicles on your federal income tax return if the loss is caused by a federally declared disaster.”
However, don’t count on claiming losses covered by insurance unless you file a timely reimbursement claim and adjust the deduction by any amount you expect to recover.
Casualty Loss Categories
There are three main categories of casualty losses related to federally declared disasters, as outlined in IRS Publication 547 or Form 4684:
- 📌 Federal casualty losses
- 📌 Disaster losses
- 📌 Qualified disaster losses
From 2018 through 2025, personal-use property losses—whether from fire, storm, or theft—are only deductible if tied to a federally declared disaster. You can claim a casualty loss deduction in the same year the damage happened, but only if you’re not expecting reimbursement from insurance.
💡 Calculating Your Casualty Deduction
When claiming a casualty deduction, subtract the salvage value from the asset’s adjusted basis, then reduce that by any insurance payouts. The remainder is your casualty loss deduction.
❓What Qualifies as a Deductible Casualty Expense?
To qualify for a deduction, casualty losses must result from sudden, unexpected events. Theft losses, on the other hand, require proof that the property was actually stolen—not just misplaced.
💡 Which Losses Don’t Qualify?
Certain types of losses are not deductible, including:
- Long-term damage from erosion, drought, or termite damage
- Losses resulting from foreseeable events (i.e., something you could anticipate)
❓How to Claim Your Disaster Loss Deduction
To claim a disaster loss deduction, fill out Part I of Section D on Form 4684 and attach it to your tax return or amendment. This process ensures your disaster loss is reflected accurately for tax purposes.
