RDSP contribution limit: how much you can contribute and when

The RDSP does not work like an RRSP or a TFSA. That trips people up, and it costs them real money. Whether you are an adult with a disability opening a plan for yourself, or a parent or family member running one for someone else, the contribution rules are where most of the confusion starts.

Three differences matter. There is a lifetime cap but no annual cap. Contributions are not deductible. And the age at which you can still contribute is not the age the government stops matching you. Get that last one wrong and you can put money into a plan that earns you nothing.

What is the RDSP contribution limit?

The lifetime RDSP contribution limit is $200,000 per beneficiary. There is no annual limit. You can contribute the entire amount in a single year if you want to. Grants, bonds and investment growth do not count toward the $200,000. Contributions are allowed until December 31 of the year the beneficiary turns 59.

That $200,000 follows the person, not the plan. A beneficiary can only hold one RDSP at a time, and every contribution ever made to it counts, no matter who wrote the cheque. Rollovers from a deceased parent's RRSP or from an RESP also count against the same $200,000, as CRA sets out in its RDSP limits guidance. Money moved directly from one RDSP to another for the same beneficiary does not.

The absence of an annual cap is the part people find strange. With a TFSA you get a set amount of room each year. With an RDSP you get one big number and total freedom on timing. That freedom is a trap, and the section on front-loading below explains why.

Who can contribute to an RDSP?

Anyone can contribute, as long as they have written permission from the plan holder. Grandparents, siblings, family friends and the beneficiary themselves can all put money in. The holder controls who is allowed to contribute, so if you are the holder and not the beneficiary, that permission is yours to give.

Two conditions catch families out. The beneficiary must be a resident of Canada each time a contribution is made. And contributions are not refundable to the person who made them, which CRA states plainly. Once your money is in, it belongs to the plan and can only ever be paid out to the beneficiary. Treat a contribution as a gift, because legally that is what it is. If you are still choosing where to open the plan, you can open and manage an RDSP online.

Are RDSP contributions tax deductible?

No. RDSP contributions are not tax deductible. You do not get a deduction the way you would with an RRSP, and contributing will not lower your taxable income this year. The benefit sits somewhere else. Your money grows tax sheltered inside the plan, and the government may add grant and bond on top.

This is the single most common wrong assumption about the RDSP, and CRA is explicit about it. If you are looking for a deduction, an RRSP does that and an RDSP does not.

So what do you actually get? Two things. First, nothing inside the plan is taxed while it grows. Second, and this is the real return, the government may match your contributions. For a beneficiary in the lower income band, $1,500 contributed can attract $3,500 in grant. No RRSP deduction comes close to that rate of return.

On the way out, the money splits. Your contributions come back tax free. The grant, the bond and all the investment growth are taxable income to the beneficiary in the year they are withdrawn, not to you as the contributor. Many beneficiaries have modest taxable income, so the tax on that portion is often small.

None of this is available without Disability Tax Credit approval. If you are not approved yet, that is the first step, and you may also be owed a refund for past years. You can check with a free DTC refund estimate.

Should you front-load the $200,000 or spread contributions out?

Spread it out. Grant is paid on what you contribute each year, so one large contribution collects a single year of grant and nothing afterwards. Contributing $1,500 in a year attracts the maximum $3,500 in grant. Front-loading the full $200,000 can forfeit tens of thousands of dollars in matching money.

Here is the arithmetic. Employment and Social Development Canada confirms the grant maximum is $3,500 in a year and $70,000 over a lifetime, and that $1,500 is the contribution needed to attract the full annual amount. Twenty years of $1,500 contributions costs you $30,000 and collects the entire $70,000. Put $200,000 in on day one and you collect $3,500, because your contribution room is gone and you cannot contribute again to trigger any more matching.

The figures above assume a beneficiary in the lower family income band with no unused entitlement to catch up on. Read that last row carefully, because it is the answer for most families with a large sum to place. You are not choosing between contributing $200,000 and contributing $30,000. You collect the grant first at $1,500 a year, then add the larger amounts once the $70,000 is banked. The room is still there.

Two things change the picture. If the beneficiary was approved for the DTC in past years without an RDSP, unused grant is carried forward for up to 10 years and the annual grant maximum rises to $10,500, so a larger contribution is justified while you catch up. And if the beneficiary is close to the year they turn 49, you have fewer years left to collect, which argues for contributing harder now. Your February Statement of Entitlement tells you the exact amount to contribute that year. The grant and bond rules go through the matching bands in detail.

What is the RDSP contribution age limit?

You can contribute until December 31 of the year the beneficiary turns 59. Grant and bond stop earlier, on December 31 of the year they turn 49. That leaves a ten year window where contributions are allowed but the government adds nothing to them. Most people should not contribute during that window.

The two ages are set separately, which is why families miss it. ESDC says it directly: after December 31 of the year you turn 49, you can keep contributing until December 31 of the year you turn 59, and you will not receive a matching grant during that time.

A plan can still be opened for someone until the end of the year they turn 59. Opening at 55 is not pointless, since contributions grow tax sheltered and a withdrawal is taxed in the beneficiary's hands. But you are buying tax shelter only, not free government money, and you should decide with that clearly in mind.

What happens when you reach the $200,000 limit?

You stop. Once total contributions reach $200,000, the plan cannot accept any more, and your financial organization tracks the running total across every contributor. There is no monthly penalty tax to worry about the way there is with a TFSA over-contribution, because the contribution is refused rather than accepted and taxed.

Rollovers eat the same room. If a parent or grandparent leaves RRSP or RRIF proceeds to a financially dependent child or grandchild, or you move money from an RESP, that amount counts toward the $200,000 and attracts no grant. With $50,000 already contributed, a rollover is capped at $150,000.

One more trap. Any contribution above the amount needed to attract that year's grant is called an unassisted contribution, and ESDC warns that it cannot be withdrawn without triggering repayment of grant and bond. Money that went in without earning a match is not easy money to take back out.
