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

Keep these records for at least 3 years after filing (6 years if you under-reported income substantially): receipts, invoices, bank/credit card statements showing the expense, Form 4562 as filed, and any correspondence from payors or institutions.
