In that case, with prior-prior reporting, if the grandfather waits until January of your son's sophomore year to provide a gift for educational expenses, none of it will be reported on a financial aid form before your son graduates, assuming he completes his degree requirements in the course of four normal academic years. In other words, if the first gift is made in January 2023, it would need to be reported on financial aid forms for the 2025-2026 academic year, but if your son graduates in four years he will be done after the spring 2025 semester.
