Minimum contribution
The minimum amount that can be contributed to a CollegeAdvantage account is $25 (Fifth Third 529 Certificates of Deposit require a minimum investment of $500).

Maximum account value 
Each Beneficiary in CollegeAdvantage has a maximum account value that applies to all accounts opened for him or her. The maximum account value currently in effect for 2010 is $345,000. This amount will be adjusted to reflect the changing costs of higher education.

Contributions for any Beneficiary will be rejected (or if accepted, returned) if the amount of the contribution would cause the aggregate amount held for the Beneficiary to exceed the maximum contribution limit.

$2,000 Ohio state tax deduction
CollegeAdvantage is the only 529 college savings program that allows Ohio taxpayers to deduct their contributions from Ohio taxable income. Each contributor (or married couple) can deduct up to $2,000 per beneficiary, per calendar year, with unlimited carry forward in future years.

For example, if you contributed $2,000 to accounts for each of your three children, you could deduct $6,000 from your taxable income for state of Ohio income taxes. Or, if you contributed $6,000 for one child in one year, you could deduct $2,000 from your state of Ohio taxable income in each of the next three years.

The deduction is not limited to the parents of the beneficiary. Any person contributing to a beneficiary's account is eligible to take the deduction: parents, grandparents, other relatives, even family friends. Each contributor who is an Ohio taxpayer can take the Ohio state tax deduction.

Contributors other than the account owner will not receive a statement at the end of the year detailing information of account balances. Such contributors should instead maintain their own record of contributions made under the account for state of Ohio tax deduction purposes.
