I have a new HSA account (my husband retired and is now covered by Medicare as of 3/1/2023). I was on his HDP for all of 2022 and remain on a HDP. Can I fund my new HSA for 2022 even though the account did not become active until 2023? I am self-employed and did not put any money into an HSA for 2022 - we previously funded an HSA (which paid any extra medical expenses for both of us) via my husband's job.
