The 2025 Form 4684, officially titled "Casualties and Thefts," is issued by the Internal Revenue Service (IRS) to assist taxpayers in reporting losses resulting from casualty or theft events. It serves as an essential tool for taxpayers to calculate deductible losses on their federal income tax returns. Casualty losses arise from sudden, unexpected, or unusual events like natural disasters, fires, and accidents, whereas theft losses relate to unlawful or wrongful takings of your property not regained by the end of the year.
IRS guidelines specify that Form 4684 must be used to report casualty and theft losses on personal, business, or income-producing properties. Not every loss qualifies for deduction; the taxpayer must show declines in value and explain any compensative sources like insurance claims. Specific IRS publications offer further directions on completing the form correctly, including Publication 547, which covers casualty, disaster, and theft losses.
Form 4684 can be submitted along with your federal income tax return through:
The form must be filed by the same deadline as your federal tax return, typically April 15th for most individual taxpayers. Extensions may be filed, but interpretation of deadlines is critical, as delinquency can result in penalties.
Failing to accurately report or file Form 4684 can lead to IRS-imposed penalties, including fines and delayed processing of returns. Taxpayers must ensure correctness and include supporting documentation for claims.
Form 4684 is available for individuals, small businesses, and corporations who have sustained uninsured losses due to casualty or theft events. The deductions apply only when losses surpass 10% of the taxpayer's adjusted gross income (AGI) after subtracting a $100 dollar-for-dollar reduction per loss.


Both digital and paper versions of the form hold the same legal weight. Digital submissions via e-file offer faster processing times, with streamlined support in tracking submission status and managing revisions. Conversely, paper versions cater to those who prefer or require formal paperwork submission.
Businesses prone to environmental risks or located in areas with high burglary rates, such as retail stores, restaurants, and service-based entities, significantly benefit from Form 4684. Completing it correctly can help offset horrendous financial blows and economic setbacks resulting from covered losses.
