7 Costly Financial Mistakes High-Income Families Make When Paying for College

College is one of the biggest expenses your family will face, and if you earn too much to qualify for traditional financial aid, it’s easy to assume your only option is to write the check and move on. But that mindset often leads to missed opportunities. Many high-income families are overpaying for college without realizing it, simply because they made preventable financial mistakes. Here are seven of the most common we see and what to do instead.

1. Paying Tuition from the Wrong Account

One of the fastest ways to lose out on valuable tax credits is to pay tuition from a 529 plan before covering the first $4,000 out-of-pocket. The American Opportunity Tax Credit (AOTC), worth up to $2,500 per student, requires that the first $4,000 of qualified expenses be paid with non-tax-advantaged money.

If you use a 529 plan for the full amount, you eliminate your ability to claim the credit, even if you qualify otherwise. To maximize tax benefits, always pay the first $4,000 from cash, a regular checking account, or the student’s earned income.

2. Assuming You’re Not Eligible for Financial Aid

Families with incomes over $180,000 often assume they’re automatically disqualified from financial aid. That’s not always true. Some colleges use different formulas that consider factors like the number of children in college or the source of your assets.

Even if need-based aid is off the table, merit-based aid is still widely available and often goes to students from high-income households. Failing to apply means you’re removing yourself from consideration before the school has a chance to evaluate your situation.

3. Claiming Your Child as a Dependent Without Running the Numbers

Most parents think it’s a given to claim their college student as a dependent. However, depending on your income level, this action might block your child from qualifying for refundable tax credits like the AOTC.

In some cases, it’s more advantageous for the student to file their own return and claim the credit themselves, especially if they’ve earned income. If your income is too high to benefit and your child meets IRS requirements, this strategy can shift thousands of dollars back into your household.

4. Triggering the Kiddie Tax Without Realizing It

Shifting assets to your child can seem like a good idea, but it can trigger the kiddie tax—a rule that taxes unearned income (over $2,600 in 2024) at your rate instead of your child’s. That includes capital gains, dividends, and other passive income.

If you’re planning to help your child fund college by transferring investments, make sure you understand how the income will be taxed. Earned income (like wages from a job) is generally exempt from the kiddie tax and can often be used more efficiently for tuition.

5. Overfunding or Misusing a 529 Plan

The 529 plan is a valuable tool, but only when used correctly. Many high-income families overfund these accounts or use them at the wrong time, missing out on more strategic ways to save.

In some situations, using a 529 too early can disqualify you from tax credits. In others, having a grandparent own the plan instead of a parent can negatively affect financial aid eligibility. You should also consider whether 529 funds will be needed for graduate school or younger siblings before pulling large amounts too soon.

6. Paying Without Considering Timing

Tuition payments are only eligible for tax credits in the year they’re paid, not the year the student attends school. If you wait until January to pay for the spring semester, that payment may apply to the following year’s return.

Strategically paying tuition before year-end can allow you to stack more credits in one tax year or avoid losing them in a year where your income spikes. On the flip side, waiting to pay can help you line up the expense with a lower-income year for better results.

7. Relying on a Standard Tax Return to Catch the Savings

Many accountants simply plug in the numbers. They don’t ask if you structured your payments to maximize credits or shifted income strategically to your student. That means you could leave thousands on the table without knowing it.

Tax-smart college planning often falls between the cracks. It’s not part of traditional financial aid counseling, and it’s not something most tax preparers are looking for. You have to be intentional if you want to take full advantage of what the IRS legally allows.
