With members saving for their children's college education or who just shelled out thousands of dollars to pay this semester's bill, credit unions take note: September is National College Savings Month. Congress designated the month in 2003 following requests by the National Association of State Treasurers and the College Savings Plan Network.

It's not only a reminder about the need to save for college, which can soak up close to $250,000 for four years at a private institution (or about one-third to one-half that at a public four-year college) but a month when several 529 college savings plans are giving away several hundred or several thousand dollars to state residents enrolled in their plans.

This year, Georgia and Oklahoma are each offering a $5,529 prize to the parents or grandparents of children born in 2015, and 2014, respectively, as well as several $1,529 prizes, according to Savingforcollege.com. Connecticut is offering a $1,529 gift; Nebraska and Utah several $1,000 prizes; and Kentucky, North Carolina and Ohio several $529 prizes. California is offering several $500 awards for students ages 3 to 14. All these prizes will take the form of contributions to state 529 plans. Deadlines for entries vary, from late September until the end of December, except for Oklahoma whose deadline is April 14, 2016, just before tax day.
