Thanks. I'm aware that medicare enrollment by the policy holder prevents HSA contributions.
Looking at your answer - about 3/4 of the total insurance premium is paid directly to the insurer by my former employer, and I pay 1/4 to the insurer. My share exceeds the monthly insurance company HSA contribution, and I pay my share with post tax dollars. The insurance plan brochure says "a portion of your monthly health plan premium is deposited to your HSA" and calls it a "premium pass through contribution." I'm not aware of any way of actually tracking the source of funds used to make the contribution. Given that the former employer paid 3/4 of the premium, is that a sufficient basis to conclude that the insurer's HSA contribution is "made on my behalf" with post tax dollars, and therefore included on line 2 of the form 8889, and thus deductible by me?
