Thank you for your question,
Your child must first claim the tuition amount on their own tax return. If there is any amount left over after your child has claimed the tuition amount, they have two choices: transfer it or carry it forward. This comes up a lot since students don’t typically earn a lot of income while going to college or university.
Your child can transfer up to $5,000 of the tax credit, less the amount used to reduce tax owing. So if they reduced their tax owing by $1,000, the most that can be transferred is $4,000. The tuition amount can be transferred to their parent, grandparent, or spouse/common-law partner.
