HSA Excess contribution withdrawal after tax due date
Due to retroactive Medicare assignment, I was notified on 4/16/26 that my coverage will start on 9/25. By that time, I had already submitted my 2025 Tax Return with HSA contributions for full 2025 year in amount of $9500. So, based on IRS 8889 form instructions I recalculated my maximum contribution for 2025 to be $6367 and requested my HSA custodian for ROE in amount $3183. Amount they actually refunded was 3109.84 due to negative earnings (losses) in amount $-73.16.
I understand that I have to submit amendment to my 2025 Tax return and I would like to use 6 months extension rule to prevent excess penalty taxes. When I used Turbotax it calculated correct HSA excess amount ($3183) but :
- in HSA questionary I do not see where I can enter actual value ($3109.84) I got refunded to get it listed in 8889-line 14d as requested by IRS.
Form 8889 Line 14b Instructions
Include on line 14b any distributions your HSA made in 2025 that qualified as a rollover contribution to another HSA. See Rollovers, earlier. Also include any excess contributions (and the earnings on those excess contributions) included on line 14a that were withdrawn by the due date, including extensions, of your return.
- I also do not see how can I add “Filed pursuant to section 301.9100-2” to the top of 1040-X form to request 6 months extension
Form 8889 Line 13 Instructions
Note. If you timely filed your return without withdrawing the excess contributions, you can still make the withdrawal no later than 6 months after the due date of your tax return, excluding extensions. If you do, file an amended return with “Filed pursuant to section 301.9100-2” written at the top.
