With the next tax law, i am trying to understand what i can use the 529 funds for. I believe i can use them for K-12 before and aftercare for both my sons, as my wife and I both work. Prior to 2018, I contributed 5,000 annually into a FSA to pay for younger son's daycare and now that he starts Kindergarten this September, I want to see if i can continue having an FSA in addition to using the 529.
