Is there a deadline for RESP contributions?

You'll receive the Canadian Education Savings Grant (CESG) grant for the calendar year in which you make the contribution. If you don't contribute enough to receive the maximum $500 grant in a given year, the unused amount can be carried forward to future years. You can catch up on one year at a time - so each year, you can receive the $500 grant for that year plus up to $500 for a previous year.
