My family were covered by my spouse's family HDHP plan from Jan through Oct, and he has made some contributions to his HSA account. We will switch our family coverage to my family HDHP plan in Nov and Dec, and I will also make some contributions to my HSA. So throughout the entire year, we are covered by one family HDHP plan, just in Jan~Oct from my spouse's employer, and in Nov and Dec, through my employer. My question is wether there is a HSA contribution limit separately for me and my spouse, i.e., whether he can contribute all $8300 to his account and I contribute $0 to my HSA account, or he can contribute $5000 to his account and I contribute the rest of $3300 to my HSA account, or our contributions have to match the ratio of months we hold the HDHP (8300*10/12 for my spouse, and 8300*2/12 for me )? Thanks!
