Sec. 529 plan is tax-free accumulation, so the sooner the account is established and funded, the better. A special provision of Sec. 529 allows those who are concerned with the annual gift tax limitations, currently $15,000, to contribute five years’ worth of contributions ($75,000) up front. These limitations apply to each contributor, but if there are multiple contributors, such as parents, grandparents, aunts and uncles, huge amounts can be contributed up front and provide the greatest long-term growth.
