My wife and I each have HSA accounts through our employers. We calculated the deductions wrong, and now we have $13 in excess contributions. The bank will charge $25 to refund this, so I'm wondering if it would be better to just take the penalty. Would the only penalty on the excess contribution be the 6% excise tax? The IRS says that "The excise tax applies to EACH YEAR the excess contribution remains in the account." Does this mean that I would still need to withdraw the $13 in 2017? Or do I apply the $13 to my 2017 contributions, i.e. in 2017 I only contribute $6750 - $13?
