- ✓These are sticker prices. They leave out scholarships, grants, and discounts.
- ✓The average discount is a starting point. It is what first-year, full-time students at that college got off the price, on average. It adds up grants and scholarships from the federal government, the state, and the college. Loans do not count. It counts only students who got federal aid, and it comes from the U.S. Department of Education.
- ✓Ask each college what it offers. Your discount depends on family income, grades, and each college's own programs. Some colleges match the tuition of your home state.

Real-life case study: see how this financial planner tracks his 529 receipts to maximize tax savings
Every dollar you take out of a 529 needs a receipt.
Your 529 plan reports what you take out to the IRS on Form 1099-Q. If the IRS asks, your receipts prove the money paid for school. Without them, you pay income tax plus a 10% penalty on the growth.
“At the end of the year, I use the Shoeboxed reporting (which is great) to see how much I should pull from the 529 to reimburse myself. (and I retain the reports in case the IRS wants to see backup)”

- Tuition
- Books
- Room and board
- Computer
-
Step 4
He pays her back
Only after the receipt comes in, so the receipts come in fast
-
Step 5
The report adds it up
At the end of the year, Shoeboxed totals each category
-
Step 6
He takes that much out of the 529
And keeps the report in case the IRS asks
He has 2 children, so he puts each child's initials in the category names. Then each report shows one child.
