Optum Bank

Optum's official form states verbatim: 'Interest and earnings will not be calculated on your behalf. Please work with your tax advisor to calculate if applicable.' Most explicit holder-computes-NIA disclaimer of any HSA custodian researched.

Known quirks

1. 1Form has two separate dollar-amount fields the holder must fill in: 'Contribution Amount to Remove' and 'Investment and Interest Earnings Amount to Remove.'
2. 2Form explicitly forbids the obvious workaround: 'you may not withdraw the excess directly. Instead, you must request an Excess Contribution refund by submitting this signed and completed form.' Direct withdrawal would be coded as a normal distribution and reported incorrectly.
3. 3Holder selects either EFT (requires a linked personal banking account) or paper check delivery.
4. 4Companion form 'HSA Return of Contribution in Error' exists for true mistake-of-fact reversals (different IRS treatment than excess removal).
5. 5HSA NIA is taxable in the year RECEIVED (per §223(f)(3)) — report on Form 8889 Line 14b and Schedule 1 Other Income for the year of distribution.

Process at Optum Bank

1. Confirm the contribution is in fact excess (limit lookup, MAGI check).
2. Compute NIA — required; custodian will not calculate.
3. Submit the Health Savings Account.
4. Allow processing time per the custodian's stated SLA (typically 3–10 business days).
5. Receive Form 1099-R (IRA) or 1099-SA (HSA) the following January with the applicable distribution code (8 / P for IRA current vs prior-year correction).
6. Report the earnings (NIA) as taxable income — in the year of distribution per IRC §223(f)(3).
