Q: "My daughter will be starting college this fall. I’m estimating the tuition will be about $25,000 each year. I’ve got about $45,000 put aside in a 529 for her. When should I tap that money?" —Henry Winkler, Colorado

A: The first thing you and your daughter should do is fill out a FAFSA, the federal financial aid application. Even if you think your household income will be too great to qualify for aid, it's worth applying just to be certain, says Mark Kantrowitz, publisher of Edvisors.com, a website that helps people plan and pay for college. "I have seen many cases where families assume they won't receive any aid, but actually do qualify based on the number of children they have currently attending college or because the high costs of the tuition resulted in a lower than expected family contribution amount."

Don't worry that the savings you currently have in your 529 will hurt her chances for aid either. Federal aid will be reduced by no more than 5.64% of the value of the account and account distributions are not considered income, Kantrowitz says.

Next, she should apply for the most available in federal direct student loans. In her first year, she can borrow $5,500. In her second year, $6,500, and any of the years following up to $7,500. Because you only get to borrow a certain amount in these direct federal student loans—which have much lower interest rates than Parent PLUS loans or private loans—it's worth borrowing the max each year and accruing that interest rather than waiting and trying to borrow the full cost of college her third or fourth year, says Kantrowitz.

If you have other savings accounts you can draw from, Kantrowitz recommends setting aside $4,000 a year from such an account for your daughter's college education so that you can take advantage of the American Opportunity Tax Credit.

With this credit, you get 100% of the first $2,000 you spend on tuition, fees and course materials paid during the year, plus 25% of the next $2,000. The credit is worth $2,500 off your tax bill. Also, 40% of the credit (up to $1,000) is refundable, which means you can get it even if you owe no tax.

The caveat: You will need to have a modified adjusted gross income of $80,000 or less, or $160,000 or less for married couples, a year to get the full benefit. If you earn more than $90,000 or $180,000 for joint filers, you cannot claim the credit.

You cannot use any of the funds from your 529 to qualify for the tax credit since that plan is already a form of tax-free educational assistance. If you do not have an additional $4,000 a year to put toward her education, you can also qualify for the credit by using the student loan amount she received—but just know that you may not be also able to claim the student loan deduction on that amount since you've already received a tax break on it, says Kantrowitz. (Right now you can claim both, but Kantrowitz says that could change in the future.)

After deducting any grant aid, her student loan sum, and the $4,000 from another savings account, pay the remaining education expenses with funds from the 529 plan.

"Under this plan it is likely your 529 will be exhausted after her third year of college, or sooner if you don't put aside that additional $4,000 for the tax credit each year," says Kantrowitz.

To make up the difference you'll need to secure another loan. If you own a home, consider home equity financing before PLUS loans, since the latter currently carry a 7.21% interest rate and come with an “origination” fee of about 4.3% of the principal amount you borrow.

If you must take the PLUS, you might be tempted to try to lock in current interest rates by borrowing to cover the first two years' worth of expenses. But you'd end up having to borrow more since she'll be getting less federal loan money those first two years, and you'd have to pay two more year's worth of interest. Even with possible rate increases, you're still better off taking the PLUS loans in her last two years.
