RESP Decision Guide: How Much, How Late, and What If They Don't Go?

Question 0: Is your family income low enough for free money with no contribution?

Before any strategy question, check this one, because it is pure upside and it is massively under-claimed.

The Canada Learning Bond pays $500 in the first year of eligibility plus $100 a year until the child turns 15 — up to $2,000 — to lower-income families, and it requires no contribution whatsoever. You open an RESP, deposit nothing, and the government deposits money. Hundreds of thousands of eligible Canadian children have never received it, almost entirely because nobody told their parents it existed.

Eligibility follows family net income and family size, with the threshold around $57,375 for families with one to three children. If you are anywhere near that, open an RESP at a provider with no account fees and claim it. There is no version of this decision where waiting helps.

Question 1: RESP or TFSA for education money?

This is the real question for families above the CLB threshold, and the answer is usually "RESP first, but not RESP only."

The RESP wins on the grant, and it is not close. A guaranteed, immediate 20% return on the first $2,500 each year is better than any investment you will find. Nothing in a TFSA competes with a government match. For the first $2,500 a year, the RESP is simply the right answer.

Beyond the matched amount, the comparison gets more even:

• RESP beyond $2,500/yr: still tax-sheltered, and growth is eventually taxed in the student's hands — usually at close to zero, given tuition credits and low income. But the money is committed to education, with penalties if it isn't used that way.
• TFSA: no match, but no strings. If your child skips post-secondary, takes a trade, gets a scholarship, or you need the money for something else entirely, TFSA money is simply yours.

A common and sensible split: contribute exactly enough to the RESP to capture the full grant each year, then put additional education savings in a TFSA. You get every dollar of free money without over-committing to one very specific future for a five-year-old.

Question 2: How hard should you catch up?

If you started late, the arithmetic is unforgiving in one direction and forgiving in the other.

Unforgiving: you can only claim one extra grant year at a time. $5,000 in a year gets you $1,000 of basic grant, and $10,000 gets you the same $1,000. Grants stop after the year the child turns 17, so from the year they turn 11 the full $7,200 of basic grant is no longer reachable — seven years at $1,000 is $7,000, and it falls by $1,000 for each further year you wait.

Forgiving: if your child is 10 or under, you have not lost anything yet. Every dollar of unclaimed room is still banked and waiting. A parent who has contributed nothing for eight years can still collect the entire $7,200 by contributing about $3,400 a year from age 8 — no more total money than the steady $2,500-a-year plan would have required, just concentrated into fewer years.

So the answer scales with the child's age. Under 10: catch up at a comfortable pace, you have room to breathe. Age 11 to 15: contribute $5,000 a year if you can at all, because each year you delay permanently deletes $1,000 of free money. Age 16 or 17: check the teen rule below before assuming any grant is available.

Question 3: Will your teenager still qualify at 16 and 17?

Two extra years of grant hang on a condition most parents have never heard of. A child aged 16 or 17 receives CESG only if, before the end of the year they turned 15, either $2,000 was contributed to the RESP and not withdrawn, or $100 was contributed in each of any four years.

This creates one of the few genuine deadlines in Canadian personal finance. If your child is 14 or 15 and has no RESP, opening one and depositing $2,000 before December 31 of the year they turn 15 preserves up to $2,000 of grant that otherwise vanishes. If your child is already 16 and neither condition was met, no contribution will produce grant — an RESP may still be worth opening for the tax-sheltered growth and the income-splitting at withdrawal, but the free money is gone.

Question 4: What if your child doesn't go?

Worth understanding before you commit, because the outcomes are worse than most parents assume, and the mitigations need setting up in advance.

• The grant goes back. All CESG is returned to the government. You never keep it. This is the single most important thing to know: the grant is not yours, it is your child's education's.
• Your contributions come back tax-free. You put in after-tax dollars, and you get them out with no tax.
• The growth is expensive to extract. Taken as an Accumulated Income Payment, it is taxed at your marginal rate plus a 20% penalty. To qualify, the plan generally must have been open at least 10 years and the beneficiary must be 21 or older.
• Or roll it into your RRSP. Up to $50,000 of the growth can move into your RRSP if you have contribution room, avoiding the penalty entirely. Preserving RRSP room is therefore a quiet form of RESP insurance.
• Or change the beneficiary. A family plan lets you redirect the money — and often the grant — to a sibling. If you have more than one child, a family plan is usually the better structure for exactly this reason.

Also worth knowing: "post-secondary" is broader than university. Trade schools, apprenticeships, CEGEP and many part-time and short programs qualify. The plan can also stay open for 35 years, so a child who works for a few years before studying has not cost you anything.

The most common mistake: treating December 31 like the RRSP deadline

The RESP contribution deadline is December 31, with no 60-day grace period into the new year. A contribution made in January counts against the new year's grant room, not last year's.

On its own, missing the date is survivable — the room carries forward. The problem is that it burns one of your limited catch-up years, and catch-up capacity is exactly what runs out as a child approaches 17. A parent of a 13-year-old who "means to get to it in January" has quietly turned a recoverable position into a $1,000 loss.

A second, smaller version of the same mistake: contributing far more than $2,500 in a single year in the belief that a big deposit earns a big grant. It does not. Above $5,000 in a catch-up year, the extra money earns no match at all — it just grows tax-sheltered, which a TFSA also does without committing the money to education.

A short version, if you want one

If your family income is near or below the CLB threshold, open an RESP today and claim up to $2,000 that requires no contribution. Otherwise contribute $2,500 a year for the full basic grant, or about $5,000 a year if you are behind and the child is 10 or under — you can still get every dollar. From age 11 each year of delay permanently costs $1,000, so move faster. Get $2,000 in before the end of the year your child turns 15 to keep the last two grant years alive. Use a family plan if you have more than one child, keep RRSP room available as a fallback, and put education savings beyond the matched amount in a TFSA rather than over-committing to a future your child hasn't chosen yet.
