529 plan aggregate limits Unlike IRAs or 401(k)s, there are no annual contribution limits for 529 plans. However, there are maximum aggregate limits, which vary by plan. Under federal law, 529 plan balances cannot exceed the expected cost of the beneficiary’s qualified higher education expenses. Limits vary by state, ranging from $235,000 to $529,000. This amount represents what the state believes to be the full cost of attending an expensive school and graduate school, including textbooks and room and board. If your plan is close to the limit don’t worry about future earnings in the account pushing it over. The funds can remain in the account without penalty, but the family will not be able to make any future contributions unless a market drop brings the account balance back down.
比如网上搜US median household income, 也是税表上全家的adjusted gross income 吗？ 所以是把401K, FSA, HSA都除掉后的收入吗？ 这样的话岂不是average income $6,8000,但其实可以是将近10,8000？ 如果俩人都401K存满的话
西方都讲税前收入，中国都讲扣掉五险一金和个税的税后收入，因为没有西方的各种plan和税的最后清算的多退少补。
不会吧，我的W2上面的wage,是已经除去了401K的啊，IRS怎么会知道你存了多少401K呢？IRS全国统计家庭收入平均值的时候必须是用的W2吧？所以不都是去掉了401K那些的吗
IRS什么都知道。
所以是税前，算上401K今年存的，也算上股票bonus,对于工薪族来说的全部收入是吧？
是税前。W2中的第一栏wage是包括401K的，而1040表中asjusted gross income是除掉了免税收入（如你列举的401K，FSA，HSA）后的收入。
Are you serious? 不可能啊，难道我每年都比offer上的工资少给了1、2万？明明就是工资减去401K啊
怎么可能 所有的W2的第一栏都是federal wage，绝对都是exclude 401k contribution
一种是Survey调查，都是自保的收入。
所以要看来源。
这个make sense
