I have one in private school and one that is homeschooled.
I am very curious to find out what strings are attached to the homeschooling part. I know some Canadian provinces offer tax benefits for homeschoolers but there are rules about using government-approved curriculum, no religious materials can be purchased, etc.
Here is a link to the current 529 plan rules. A couple of interesting points:
Q. What is the main advantage of a typical 529 plan?
A. Earnings are not subject to federal tax and generally not subject to state tax when used for the qualified education expenses of the designated beneficiary, such as tuition, fees, books, as well as room and board. Contributions to a 529 plan, however, are not deductible.
Q. Can anyone set up a 529 plan?
A. Yes. You can set one up and name anyone as a beneficiary — a relative, a friend, even yourself. There are no income restrictions on on either you, as the contributor, or the beneficiary. There is also no limit to the number of plans you set up.
Q. Are there contribution limits?
A. Yes. Contributions can not exceed the amount necessary to provide for the qualified education expenses of the beneficiary. If you contribute to a 529 plan, however, be aware that there may be gift tax consequences if your contributions, plus any other gifts, to a particular beneficiary exceed $14,000 during the year. For information on a special rule that applies to contributions to 529 plans, see the instructions for Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return.
Q. Who controls the funds in a 529 plan?
A. Whoever purchases the 529 plan is the custodian and controls the funds until they are withdrawn.
Q. Each 529 plan account has one designated beneficiary. What does that mean?
A. A designated beneficiary is usually the student or future student for whom the plan is intended to provide benefits. The beneficiary is generally not limited to attending schools in the state that sponsors their 529 plan. But to be sure, check with a plan before setting up an account.
Q. Can I change the beneficiary of a 529 plan I have set up?
A. Yes. There are no tax consequences if you change the designated beneficiary to another member of the family. Also, any funds distributed from a 529 plan are not taxable if rolled over to another plan for the benefit of the same beneficiary or for the benefit of a member of the beneficiary’s family. So, for example, you can roll funds from the 529 for one of your children into a sibling’s plan without penalty.
Q. What is an eligible educational institution?
A. An eligible educational institution is generally any college, university, vocational school, or other postsecondary educational institution eligible to participate in a student aid program administered by the U.S. Department of Education.
Q. I have not set up a 529 plan for my child. Can I start one now and take advantage of this new computer benefit?
Answer: You can start one anytime. But the benefit of a 529 plan comes with the tax-free withdrawal of earnings that build up in the plan based on the contributions made. Like other types of savings accounts, earnings are usually a function of time. A 529 plan which is set up while the student is already enrolled in college or in other postsecondary education may not accrue enough earnings to be of immediate benefit. However, that doesn’t mean that such a student wouldn’t benefit from a 529 plan as his or her postsecondary education continues.
So the devil is in the details, as always with our wonderful tax code. Earnings are exempt but currently the actual donations are not exempt.
In addition, new rules need to be created that expands the use of 529 plans beyond "approved DOE" schools.
