I have an HSA-compatible HDHP starting next year, and I plan on contributing to an HSA. I have self-coverage only through my employer. My wife is under 26 and still on her father's HDHP, and he contributes to an HSA.
My wife and I will be filing jointly next year. For tax purposes, does her father's contribution to his HSA count as a contribution from her for the year? In other words, will I be penalized for putting money towards my personal HSA account if her father is maxing out his account?
