Disasters are unfortunate events in the history of the US. Hurricane Milton is one of them. The disaster hit Florida and specific regions in North Carolina in the last quarter of 2024. Businesses, infrastructures, entire cities, and residents were all damaged financially too. We explain financial benefits presented by the US authorities. The US tax code allows taxpayers to deduct un-reimbursed losses caused by federally declared disasters. Hurricane Milton is among them.
Our guide presents exactly:
- Qualifying parties
- How to calculate this deduction
- How to file — with a timing strategy that most victims overlook.
Do you qualify for a Hurricane Milton casualty loss deduction?
If your property suffered un-reimbursed damage in a federally declared disaster area and the net loss clears the IRS income threshold — qualification is likely. The rules vary parallel to whether the damaged property was personal / business-use.
The IRS has 4 concrete conditions before deductions:
- Federally declared disaster area — the property must be located in a county officially declared by the federal government. Specific Florida & North Carolina counties received the designation after Hurricane Milton. It is possible to confirm the county’s status at DisasterAssistance.gov.
- Un-reimbursed loss only — it is only only possible to deduct what insurance, FEMA grants, or SBA loans did not cover. The IRS calls this a “realized loss.” More on the FEMA & SBA interaction below.
- Itemized deductions — personal casualty losses from federally declared disasters are claimed on Schedule A. In case that the standard deduction exceeds the itemized deductions, the casualty loss may not present a net tax benefit.
- The 10% AGI floor — for personal property, only the portion of the net loss that exceeds 10% of the Adjusted Gross Income (AGI) is particularly deductible.
Sarah’s Scenario: The underinsured Tampa homeowner
- Sarah lives in Tampa, FL.
- Her AGI is USD 80,000.
- Hurricane Milton caused USD 25,000 in structural damage.
- The insurance paid out USD 10,000 and left her with a USD 15,000 out-of-pocket loss.
Calculation:
- Starting with out-of-pocket loss — USD 15,000
- Subtracting the IRS’s $100 per-event reduction — USD 14,900
- Subtract 10% of her AGI ($80,000 × 10% = $8,000) — USD 6,900
Sarah’s allowable casualty loss deduction is USD 6,900
It’s less than she lost. But USD 6,900 in deductions at a 22% tax bracket is still roughly $1,518 back in her pocket. Not nothing.
Personal vs Business Casualty Loss
Business property embraces different restrictions. They’re considerably more favorable. The table below presents the critical distinctions.
Personal vs Business Casualty Loss Cheat Sheet
| Feature / Rule | Personal Property | Business / Income-Producing Property |
| IRS Per-Event Reduction | $100 subtracted per casualty event | No $100 reduction |
| Income Threshold | Net loss must exceed 10% of AGI | No AGI threshold — full loss may be deductible |
| Where You Claim It | Schedule A (Itemized Deductions) | Form 4797 — business assets / Schedule C — self-employed |
| Filing Requirement | Form 4684, Section A | Form 4684 — Section B |
| Itemizing? | Yes | No — deducted against business income directly |
| Tax Code | IRC §165(c)(3) | IRC §165(c)(1) |
David’s Scenario — freelance developer in Asheville, NC
- David is a freelance web developer. His home office in Asheville was destroyed by Hurricane Milton.
- A fallen tree wiped out USD 5,000 worth of servers and office furniture — equipment used exclusively for client work.
Since they are business assets, David faces none of the limitations Sarah did.
- No $100 reduction.
- No 10% AGI floor.
- He reports his loss on Form 4684, Section B — and it flows directly against his business income on Schedule C.
His USD 5,000 loss could lower the self-employment income — and lower his self-employment tax as well.
How do you calculate the hurricane loss without records?
No need for a formal appraisal to value the loss. The IRS presents “safe harbor” methods that accept written contractor repair estimates as valid proof of value.
The 2 Accepted Valuation Methods
In accordance with Revenue Procedure 2018-08, the IRS formally recognizes 2 approaches to calculating the casualty loss:
The Appraisal Method — a qualified appraiser is taken to document the fair market value (FMV) of the property before and after the disaster. The difference, minus insurance proceeds, is the gross loss. Precise — yet expensive & time-consuming.
The Cost of Repairs Safe Harbor (The Practical Choice) — If the repairs are:
- reasonable
- necessary
- actually restore the property to its pre-disaster condition — not improvements
the cost of those repairs might be used as a proxy for the loss in value. A written contractor estimate is proper. You do not need to have already paid the repair bills.
This method is preferred by most individual homeowners.
What If the Hurricane Destroyed Your Records?
The IRS has options for you.
- Contractor estimates for damaged property replace appraisals in most cases as indicated above
- County tax assessor records may establish pre-disaster property values — these are public records and generally available online .
- Photographs & videos from before the storm — social media, real estate listing photos, Google Street View — serve as legitimate evidence
- Purchase records might be requested from the mortgage lender or title company or state property
- Insurance company claim files generally contain pre-loss property descriptions that ca be requested
The standard is “reasonable substantiation” — not perfection.
FEMA Grants & SBA Loans Impact Deductions
It is not possible to deduct a loss that was already covered by someone else. That’s the anti-double-dip rule. The rule applies to:
- FEMA Individual Assistance grants — tax-free to receive, but they lower deductible casualty loss dollar-for-dollar
- SBA Disaster Loans — if the loan is forgiven later, the forgiven amount lower the loss — If you must repay it, it does not lower deductible loss
- State disaster relief payments — same logic as FEMA grants
A single miscalculation at any step has the potential to either shrink the refund or flag the return for IRS review. This is exactly where a CPA earns their fee.
Let Dimov Tax do the calculations
Hurricane Milton didn’t just damage property — it established a tax situation with moving layers:
- The 10% AGI floor.
- The safe harbor valuation rules.
- The option between 2 tax years.
- The interaction with FEMA & SBA proceeds.
One wrong number on Form 4684 may either leave money on the table or — worse — attract IRS attention.
At Dimov Tax, our CPAs and EAs manage hurricane loss cases exactly like this every day. Here’s what working with us looks like:

You’ve already dealt with the storm. You shouldn’t have to fight the IRS alone too. Contact Dimov Tax today for the best available options.
We present below how the timing decision breaks down — and why getting it correct can mean the distinction between a refund this month vs next spring.
How and when should you file?
Victims of federally declared disasters can claim their 2024 hurricane loss on their 2023 tax return. This strategy is authorized under IRC Section 165(i). It has the potential to put money in your hands months earlier than waiting to file the 2024 return.
Option A: Claim the Loss on the 2024 Tax Return — Standard Path
Form 4684 is filed with the standard 2024 federal tax return. Straightforward. No amended return necessary. Functions well in case of having a large 2024 income that the deduction can offset.
Option B: Claim the Loss on an Amended 2023 Return — The Fast-Cash Strategy
This is an option that’s not known widely by the victims. Under IRC §165(i), federally declared disaster losses may be claimed on the prior year’s return.
- File Form 1040-X to reopen the 2023 taxes
- Add Form 4684 reporting the Milton loss to the amended return
- The IRS processes amended returns & issues refunds — sometimes within a few weeks
If the taxes are already paid on 2023 income, the strategy converts the casualty loss into a refund check. Generally, months before the 2024 return would even be due.
Who leverages Option B:
- Taxpayers who owed substantial tax in 2023
- Anyone who needs immediate cash flow for repairs & rebuilding
- People whose 2024 income is lower than 2023 — the deduction is worth more against higher income
