RESP Grants Stop at 17. The Last Year to Start and Still Collect $7,200
The last calendar year in which you can begin contributing to an RESP and still collect the entire $7,200 of grant is the year the child turns 10. Three deadlines govern the RESP grant, and they sit at 17, 15 and 10. Grant is payable up to and including the year a child turns 17. Contribute nothing by the end of the year they turn 15 and the grant is not reduced, it is extinguished. And because the grant is capped two ways at once, by a lifetime maximum and by a ceiling on what any single year can pay, no start later than the year the child turns 10 reaches the full $7,200 of basic grant, however much money follows it. On our arithmetic on the statute, a family starting in the year the child turns 11 has already lost $200, and by the year they turn 13 the ceiling on what is still reachable is $5,000.
The same mechanism has one further consequence. Paying the whole $50,000 lifetime contribution limit in the year the child is born, which sounds like the maximum-compounding move, collects $500 of grant rather than $7,200.
The grant is capped by a rate, by a year, and by a lifetime
Three provisions of the Canada Education Savings Act do all the work.
The rate is 20%. Under s.5(2)(a), the basic grant is the lesser of 20% of the contribution and the room available, so every dollar of grant costs five dollars of contribution.
The room accrues at $500 a year. Section 5(3)(b) sets it at $500 multiplied by the number of years after 2006 in which the beneficiary was alive, up to and including the year in question, less every grant already paid for earlier years. The CRA’s Canada Education Savings Grant page puts it plainly: “Every child under age 18 who is a resident of Canada will accumulate $400 (for 1998 to 2006) and $500 (from 2007 and subsequent years) of unused CESG room.” Room starts in the birth year, so a child born this year already has $500 of it.
The year is capped at $1,000. However much room has piled up, s.5(2)(b)(i) allows no more than $1,000 of basic grant to be paid for any one year. The CRA’s wording is “$1,000 in CESG if there is unused grant room from a previous year.”
And the lifetime is capped at $7,200. Section 5(10): “Not more than $7,200 in CES grants may be paid in respect of a beneficiary during their lifetime.”
Set those last two side by side and you have the catch-up mechanism. Room arrives at $500 a year and no year can ever draw more than $1,000, so a backlog shrinks by at most $500 a year, which fixes the arithmetic of a late start before the first dollar moves.
Two consequences of the 20% rate are worth having in hand. The first is that $36,000 of contributions is the amount that converts to the full grant, whenever it is paid, which is nothing more clever than $7,200 divided by 20%. Contributing more than $36,000 does not buy more grant: a flat $2,500 a year from birth collects the whole $7,200 on $45,000 of contributions, because the pace runs on past the point where there is room left to claim. Of the $50,000 lifetime contribution limit, only $36,000 can ever convert, leaving $14,000 that earns nothing. The second is that no single year converts more than $5,000, because the grant on it hits the $1,000 ceiling.
The last useful start year is the year the child turns 10
Grant is payable only where the beneficiary “is less than 17 years of age at the end of the year preceding the contribution”, under s.5(1), and s.5(3)(a) makes room nil “if the beneficiary was 17 years of age or older at the end of the preceding year”. The CRA’s version: “The CESG is available until the calendar year in which the beneficiary turns 17.”
So the last qualifying year is the year the child turns 17, and $7,200 at a ceiling of $1,000 a year needs 7.2 years, which means eight calendar years of claiming. Eight years back from 17, counting 17 itself, lands on 10.
That 10 is the answer for the basic grant, which is what the table and the chart here are about. A family drawing the Additional CESG as well collects $1,100 in a year at the upper tier, or $1,050 at the lower one, and $7,200 at either pace needs seven claim years rather than eight. For them the last useful start year is 11.
Our calculation on Canada Education Savings Act s.5(1), (2), (3) and (10) and Canada Education Savings Regulations s.4(1)(c) and (d), for a beneficiary born after 2006 and resident in Canada throughout, contributing in each year exactly the amount that converts to grant. Basic CESG only.
| Contributions begin in the year the child turns | Qualifying years left | Most grant obtainable | Forgone |
|---|---|---|---|
| 0 to 10 | 18 down to 8 | $7,200 | nil |
| 11 | 7 | $7,000 | $200 |
| 12 | 6 | $6,000 | $1,200 |
| 13 | 5 | $5,000 | $2,200 |
| 14 | 4 | $4,000 | $3,200 |
| 15 | 3 | $3,000 | $4,200 |
| 16 | 2 | nil | $7,200 |
| 17 | 1 | nil | $7,200 |
Every figure in that third column is a ceiling under contributions timed perfectly against the room, not a prediction: contribute less than the amount that converts in a given year and the ceiling drops again.
The two ends of the plateau reach the same $7,200 by very different routes, and that is what shows why the plateau stops where it does. Start at birth and the pace is $2,500 a year, collecting $500 for each of the years the child is 0 through 13, then $1,000 collecting the last $200 at 14. It is $500 a year rather than $1,000 because nothing was ever banked: room claimed in the year it arrives never becomes a backlog. Start in the year they turn 10 and the pace is $5,000 a year, collecting $1,000 for the years they are 10 through 16 and $200 at 17, which works because $5,500 of room is already waiting in the first year. Start one year later and seven qualifying years at $1,000 give $7,000 on $35,000, with the last $200 nowhere left to go.
The same grant, and not the same outcome
Both ends of that plateau contribute $36,000 and collect $7,200. The only thing separating them is when. Here are the two schedules valued at the start of the year the child turns 18, before any tax on withdrawal from the plan, under a single constant annual return.
| Annual return | Start at birth | Start in the year they turn 10 | Gap |
|---|---|---|---|
| 4% | $68,169 | $52,505 | $15,664 |
| 5% | $76,499 | $55,119 | $21,379 |
| 6% | $85,884 | $57,860 | $28,024 |
| 7% | $96,458 | $60,732 | $35,726 |
Our arithmetic, with the same $36,000 contributed and the same $7,200 of grant collected in both columns.
At 7% the gap is $35,726, nearly five times the entire grant either family received. The grant is identical and the outcome is not, so the plateau is a statement about one line of the statute rather than about what the money comes to.
The other half of the asymmetry is in the schedules themselves. The birth starter commits $2,500 a year for fourteen years and then $1,000. The age-10 starter commits $5,000 a year for seven consecutive years and then $1,000, twice the annual commitment, with no year in which it can be missed.
Contribute nothing before the year a child turns 16 and the grant is nil
The second cliff is sharper, and it sits in the Canada Education Savings Regulations rather than the Act. Under s.4(1)(c), a contribution made in the year the beneficiary turns 16 or 17 attracts grant only if one of two prior-savings tests is met: either “a minimum of $2,000 of contributions has been made to, and not withdrawn from, RESPs in respect of the beneficiary before the year in which the beneficiary attains 16 years of age”, or “a minimum of $100 of annual contributions has been made to, and not withdrawn from, RESPs in respect of the beneficiary in at least any four years before the year in which the beneficiary attains 16 years of age”.
Those tests turn a gradual decline into a step. Our arithmetic on a family contributing $5,000 in each of the years the child turns 16 and 17, varying only what went in during the year they turned 15:
| Contributed in the year they turn 15 | Grant that year | Grant at 16 and 17 | Lifetime total |
|---|---|---|---|
| nil | nil | nil | nil |
| $1,000 | $200 | nil | $200 |
| $1,500 | $300 | nil | $300 |
| $2,000 | $400 | $2,000 | $2,400 |
| $5,000 | $1,000 | $2,000 | $3,000 |
An extra $500 in that one year, from $1,500 to $2,000, is worth $2,100 more of grant, and it is worth that because it clears the first limb of s.4(1)(c), not because of anything it earns at 20%. Below that line, with nothing contributed before the year the child turns 16, even $50,000 paid in that year earns nil.
This is the one conclusion the CRA states in its own words rather than leaving to arithmetic. From guide RC4092: “you must start to save in RESPs for your child before the end of the calendar year in which your child turns 15 years of age.”
Front-loading the whole $50,000 collects $500 of grant
Nothing in the rules stops a subscriber putting the entire lifetime limit in on day one. The limit itself is in section 204.9 of the Income Tax Act, “for 2007 and subsequent years, $50,000”, and RC4092 confirms there is no annual cap to go with it: “for 2007 and subsequent years, there is no limit.”
Go past $50,000 and the excess is taxed under s.204.91(1). RC4092 describes the charge this way: “Each subscriber for that beneficiary is liable to pay a tax of 1% per month on their share of the excess contribution.” That is the same monthly rate as the 1% a month tax on an RRSP over-contribution, with one difference worth knowing before assuming the two work alike. The RRSP version bites only above a $2,000 cushion. The RESP has no cushion: under s.204.9(1), for years after 2006 the excess amount is whatever is contributed in the year above the unused part of the lifetime limit, so the first dollar past $50,000 is already being charged.
What stops front-loading is not a limit, it is the room. Pay $50,000 in the birth year and the room that year is $500, so the grant is $500, and the lifetime contribution limit is spent with nothing left to convert in any later year. That forgoes $6,700, on our arithmetic. The identical $50,000, paced so that $2,500 lands each year against the room and the ungranted $14,000 goes in at the start, collects the full $7,200.
Where the money waits decides whether front-loading is worth it
Against that lost grant sits the argument for paying early, which is simply how compounding works over an 18-year horizon: a dollar contributed at birth has 18 years of growth behind it and a dollar contributed at 14 has four. Whether those years beat a 20% match turns on an assumption that is easy to leave unstated. We valued all three cases at the start of the year the child turns 18, before any tax on withdrawal, under a single constant annual return.
If the money waiting to be contributed earns nothing, the breakeven return is 2.63%. Above that, front-loading finishes ahead despite the forgone grant. That number is true and on its own it is misleading, because it quietly assumes the $50,000 you have not contributed yet is sitting in a drawer.
If instead it waits in a TFSA earning the same return, which assumes the roughly $33,500 still waiting at the start of the first year has TFSA room available to sit in with no competing use, there is no breakeven at all. Pacing wins at every return from 0% to 30%, by $6,700 at worst and by roughly $20,000 at a 10% return. Every dollar earns the same return either way, so the only thing the schedule changes is how much grant arrives.
The middle case is a taxable account, where the waiting balance is taxed each year at 30% of its return, a round rate we assumed rather than sourced. The breakeven there is about 5.7%.
So there are three answers, and which one applies depends entirely on where the uncontributed money sits.
The claiming deadline and the second grant
One deadline sits behind all of this. Under Regulations s.4(1)(b)(i), the application for the grant has to be made “within three years after the date of the contribution”. A contribution sitting in the plan is not the same thing as a grant claimed on it.
The $7,200 ceiling also covers more than the basic grant. Under s.5(4) of the Act, the Additional CESG adds 20% of the contribution to a maximum of $100 a year where the family’s adjusted income is at or below the Act’s first threshold, and 10% to a maximum of $50 a year where that income is above the first threshold but not above the second. It counts against the same $7,200 lifetime maximum rather than sitting on top of it, and its annual maximum does not carry forward, so an unclaimed $100 or $50 is gone.
The grant is not the subscriber’s to keep
Under Regulations s.11(1), where assisted contributions are withdrawn from a plan, “other than by way of transfer to another RESP”, at a time when no beneficiary is eligible to receive an educational assistance payment, the trustee “shall … repay to the Minister” an amount set by the formula in that subsection, and s.11(3)(a) imposes the same obligation if “the RESP is terminated”. The contributions are the subscriber’s throughout; the grant account goes back to the government. Changing the beneficiary is a repayment event too under s.11(3)(f), but not where paragraph 204.9(4)(b) of the Income Tax Act applies, which covers a new beneficiary under 21 who shares a parent with the one they replace. Redirecting a plan to a sibling is the case the rules are built to allow.
Starting early earns no extra grant, and wins anyway
Put the whole timing question together and the programme pays nothing for starting early. What a late start costs is the part no rule hands back, which makes the year the child turns 10 a backstop rather than a target. Wait until the year a child turns 12 and $1,200 of grant is gone before the first contribution is made, with no amount of money later recovering it. Start by 10 and you keep every dollar of grant, and pay for the delay in a currency the start-year table does not show.
