## Facts

### What Is Form 4684 Used For?

Form 4684, Casualties and Thefts, reports the financial hit from a fire, storm, theft, or similar event. Section A covers personal-use property; Section B covers business or income-producing property, each with different rules for figuring the deductible loss.

### Who Should File Form 4684?

Anyone who suffered a casualty or theft loss can file IRS Form 4684, but personal-use property only qualifies if the loss came from a federally declared disaster. Business owners and landlords face no such restriction and can claim losses from ordinary casualties too.

### When Is Form 4684 Due?

There's no specific Form 4684 due date; it’s attached to your regular tax return, usually April 15th. If you're claiming a loss tied to a disaster declared the following year, you can instead amend the prior year's return by October 15th.

### What Happens If Form 4684 Is Not Submitted?

If you don’t submit Form 4684 with your tax return, the IRS has nothing to support your loss claim, so the deduction gets disallowed. This means higher taxable income and possibly a notice asking you to explain the discrepancy.

### How and Where Do I File Form 4684?

Attach IRS Form 4684 to Form 1040, 1040-NR, or your business return, and file it the same way you file the rest of your return, electronically through IRS e-file or by mail to your regional processing center.
