Can You Deduct a Personal Casualty Loss? Here's What Changed
Most people assume that if something unexpected and expensive happens to their property, there's at least some kind of tax deduction available.
A tree falls on your house. A tornado damages your garage. Floodwaters destroy your belongings.
Surely that counts for something on your tax return, right? Not necessarily.
In fact, personal casualty losses have been largely nondeductible for federal tax purposes since 2018. While many taxpayers are surprised to learn that, there is some good news: this year, the rules are expanding slightly.
Here's what you need to know.
What Is a Personal Casualty Loss?
A casualty loss is damage, destruction, or loss of property resulting from a sudden, unexpected, or unusual event.
Examples might include:
Tornadoes
Floods
Hurricanes
Fires
Earthquakes
Other natural disasters
The key word here is personal. These rules apply to your personal residence, vehicles, and belongings — not business property, which follows a different set of tax rules.
What Changed in 2018?
Before 2018, taxpayers could sometimes claim deductions for casualty losses that were not fully reimbursed by insurance or other sources.
In many cases, insurance covered part of the damage, but taxpayers could potentially deduct the unreimbursed portion of their loss if they met the applicable requirements.
However, the Tax Cuts and Jobs Act significantly limited that deduction.
Beginning in 2018, personal casualty losses became deductible only if the loss occurred in an area covered by a federally declared disaster.
That meant many taxpayers who experienced significant property damage received little or no tax benefit unless the federal government officially declared the event a disaster.
For example, if a severe storm damaged your property but never received a federal disaster declaration, the loss generally wasn't deductible, even if the repair costs were substantial.
What's Different in 2026?
With losses occurring in 2026, taxpayers may also qualify for casualty loss deductions when the damage results from a state-declared disaster, not just a federally declared one.
This is an important expansion because many disasters receive state-level declarations without ever rising to the level of a federal declaration. As a result, more taxpayers may become eligible for relief when unexpected disasters strike.
While the exact rules and calculations still apply, the broader eligibility could make a meaningful difference for families recovering from property damage.
Does Insurance Matter?
Yes, insurance plays a major role in determining whether a casualty loss may be deductible.
Generally, you can only claim a deduction for losses that are not reimbursed by insurance or other sources. If your insurance company pays for the entire loss, there is typically no deduction available. However, if part of the loss remains unreimbursed, you may be able to claim that portion, assuming all other requirements are met.
This is one reason it's important to keep thorough records, including:
Insurance claims
Settlement documents
Repair estimates
Receipts and invoices
Photos documenting the damage
If you want to be especially prepared, maintaining a detailed inventory of your personal belongings can be incredibly helpful. In the event of a disaster, a home inventory can help maximize your insurance claim and provide valuable documentation if a casualty loss deduction becomes available.
Good documentation is often one of the most important factors in determining whether a loss qualifies and how much relief may be available.
Why This Matters
Most people don't spend much time thinking about casualty loss deductions until they need them.
Unfortunately, natural disasters, severe storms, and unexpected property damage can create significant financial stress. Understanding what relief may be available can help you make better decisions during an already difficult situation.
The expansion to include state-declared disasters this year gives taxpayers more opportunities to claim relief when major property losses occur.
