HOW MUCH CAN YOU CONTRIBUTE?
To qualify as a 529 plan under federal rules, a state program must not accept contributions in excess of the anticipated cost of a beneficiary's qualified education expenses. At one time, this meant five years of tuition, fees, and room and board at the costliest college under the plan, pursuant to the federal government's "safe harbor" guideline. Now, however, states are interpreting this guideline more broadly, revising their limits to reflect the cost of attending the most expensive schools in the country and including the cost of graduate school. As a result, most states have contribution limits of $300,000 and up (and most states will raise their limits each year to keep up with rising college costs).
A state's limit will apply to either kind of 529 plan: prepaid tuition plan or college savings plan. For a prepaid tuition plan, the state's limit is a limit on the total contributions. For example, if the state's limit is $300,000, you can't contribute more than $300,000. On the other hand, a college savings plan limits the value of the account for a beneficiary. When the value of the account (including contributions and investment earnings) reaches the state's limit, no more contributions will be accepted. For example, assume the state's limit is $300,000. If you contribute $250,000 and the account has $50,000 of earnings, you won't be able to contribute anymore--the total value
