FSA 没有花完，剩下的就没了，被抢了。不会回到收入里算税

FSA 的rule就是either use it or lose it.

"The IRS' use-or-lose rule states that FSA funds must be spent by the participant within the FSA's plan year. That means FSA participants typically need to spend most or all of their FSA funds by the end of the plan year. Unused funds at the end of the plan year are forfeited to the plan"

不知道被谁抢的，但肯定就没了
