Right now we have all our benefits through DH's work. I'm supposed to start a new FT job soon and since I've been PT with the company for nearly three years, I already know the benefits are way better and substantially more affordable (health insurance will be half the cost of DH's medical insurance). My question is this: DH had elected to max out his FSA account and his dependent care account for 2016.
What happens with those accounts if/when we switch to my company's benefits? Do I have to elect not to contribute to those accounts, and we use his for the rest of the year? Or will his become null, and we have to switch to mine? If he has already made the contributions from his paychecks, would we subtract that amount, then I elect to contribute the remaining amount?

Sorry if that's confusing, I should just ask my HR person hahaha.
