@Brian Gilmore This thread is helpful. I am in a more complicated situation. My family was enrolled in HDHP and contributed $3700 (including company contribution) to HSA Jan-Jun, then I changed job in July, and we enrolled in non HDHP and FSA ($1600), then I returned to the first employer recently (end of Aug), and will be back on HDHP starting Sep 1. hsa custodian told me that I made mistake, I can not contribute to FSA and HSA within the same year, even with job change, my first employer should make ‘mistaken’distribution’ to withdraw contributions from HSA account through payroll, and I can not contribute to HSA for the remainder of the year. I looked at the FSA account and it does say, plan start date is Jan1 2024 and plan end date Dec31, eligiblility date is July1, last day for spending Aug7. Is it correct that I must withdraw HSA to 0 for this year? I consulted my CPA and she did not know if this is an issue and how to fix it. I appreciate it if you have any insights on this. Thanks.
