<prompt> Human: I have 2 nephews and 2 nieces, and I have committed to myself to paying for a year of college for each, and more if they go to graduate school. The spread in ages is from 6 to 19, and for the two oldest, who have already graduated high school, I let their parents know at the Christmas of their senior years that they would be receiving this gift.Ive heard of 529 plans, and am wondering if these are the best route to go, or are there other tax advantaged plans that might be utilized. I live in a state with no state income tax, so state taxes arent a concern, but are there plans that are tax advantaged at the federal level?  <response>: For the ones out of high school, Id pay it directly to the school. You could open 529 plans now for the younger ones.
