Can You Write Off Flood Damage to Your Home?
Short answer: Only if the flood was part of a declared disaster, and only the uninsured loss after the $100 and 10%-of-AGI floors.
Personal casualty losses are deductible only from a federally declared disaster (and, starting in 2026, certain state-declared disasters), after a $100 reduction and 10% of AGI, and only if you itemize.
Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
