Worthless stock

Can You Write Off Worthless Stock?

Short answer: Yes, stock that becomes totally worthless is treated as sold for $0 on the last day of the year.

You need proof it's worthless, not just down a lot.

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.
