The Worthless Securities Deduction is a FEDERAL deduction — federal eligibility rules apply uniformly nationwide. Montana's difference is at the state-level conformity: most states "couple" with federal AGI calculations, meaning the deduction reduces your Montana taxable income too.

Some states "decouple" from federal — verify Montana's 2026 state tax form for confirmation.

Federal phase-outs depend on your modified adjusted gross income (MAGI) — high-income filers may see reduced or fully phased-out benefits.
