Help All Americans Save for College Act of 201 7 This bill amends the Internal Revenue Code to modify the tax treatment of qualified tuition programs (known as 529 plans) and ABLE accounts. (Tax-favored ABLE [Achieving a Better Life Experience] accounts are designed to enable individuals with disabilities to save for and pay for disability-related expenses.) The bill excludes employer contributions to an employee's 529 plan or ABLE account from the gross income of an individual, certain employment taxes, and taxes on self-employment earnings. The exclusions are limited to the lesser of: (1) the compensation includible in the individual's gross income for the year, or (2) $5,000 ($10,000 in the case of a joint return) for each dependent of the taxpayer who is the designated beneficiary of a 529 plan. The bill also allows an individual to deduct up to $5,000 of the aggregate contributions of the individual to a 529 plan and an ABLE account. The bill revises the 10% additional tax for distributions from a 529 plan or an ABLE account that are not used for qualified purposes to change the rate to the greater of: (1) 10%, or (2) the highest rate of income tax applicable to the taxpayer.
