What's the difference between the HSA Contributions federal vs Idaho state treatment?
The HSA Contributions is a FEDERAL deduction — federal eligibility rules apply uniformly nationwide. Idaho's difference is at the state-level conformity: most states "couple" with federal AGI calculations, meaning the deduction reduces your Idaho taxable income too.

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

What records should I keep for the HSA Contributions in case of an IRS audit?
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 8889 as filed, and any correspondence from payors or institutions.
