<p>You would have to calculate your particular situation, but the benefit may not be as much as you expect. First there is a maximum you can contribute per year. It is $12,000 per individual or $24,000 for both the spouses combined. You can make a one time contribution of $60,000 per parent or $120,000 for both parents but cannot make another contribution for 4 more years.</p>
<p>List below gives the state tax benefit by state</p>
<p>In a few states like S Carolina and W Virginia, your entire contribution is deductible (remember this is a deduction and not a tax credit). So if your marginal tax rate is 5% and you contribute $120,000, you get a tax reduction of $120,000*5% or $6000. (Again this is assuming your tax liability is greater than $6000. If it is not, then your benefits are less.)</p>
<p>On the other hand if you live in Maine ($250) or Arizona ($750) per person, your saving is not much. For example in Arizona if you and your spouse contribute $120,000 you will get a tax deduction of $1500 and that means a saving of $75. The cost of opening the account and managing it may be more than that. If your marginal tax rate is 3.5%, then your savings are even lower.</p>
<p>The advantage of a 529 plan is that it allows principal to grow tax free, so if you put $12,000 when the child is 1 year old, it will grow for 17 more years tax free.</p>
<p>If you put money in a 529 plan you have to keep records of how you spend it. So look at your specific situation and determine if it makes sense to park in a 529 fund a for a short period of time. It may or may not be worth it. A lot depends on how much money you are putting in and what your marginal tax rate is.</p>
