I had water damage to my primary residence & had a $1K deductible on my homeowners insurance. As I a paid the $1k out of pocket, can I deduct this cost?

No. Casualty loss is not deductible unless caused by a declared national disaster.

When you have items that are lost or damaged as a direct result of a natural disaster, and you live in a federally declared disaster area, you may be able to take a tax deduction for the value of the property that is not covered by your insurance.

Unfortunately, property loss or damage of property for personal use that is not the direct result of a natural disaster is not eligible for a casualty deduction.

This restriction started in 2018 and applies through 2025.
