RDSP contribution limits: the ceiling, and the number that matters more
How much can you contribute to an RDSP?
An RDSP has no annual contribution limit, only a $200,000 lifetime cap ending the year the beneficiary turns 59. Here is the amount that earns grant.
The RDSP has one hard ceiling and no annual limit. A beneficiary can receive $200,000 in contributions over a lifetime, in any pattern, until the end of the year they turn 59. Nothing forces you to spread that money out, and no one will stop you from putting in $50,000 in a single January.
That freedom is also the trap. The lifetime cap is almost never the number that should decide how much you contribute this year. The matching grant rules decide it, because a dollar contributed above the matched amount earns no grant, still counts against the $200,000, and is still caught by the repayment rules if the plan pays out early. This page separates the ceiling from the number that actually matters.
How much can you contribute to an RDSP?
The lifetime limit is $200,000 for a beneficiary, counted across every RDSP they have ever held. Contributions are allowed until December 31 of the year the beneficiary turns 59. There is no annual cap under that ceiling, so the yearly amount is a planning decision rather than a legal one.
The Canada Revenue Agency states the rule plainly in RDSP limits, transfers, and rollovers: no annual limit, a $200,000 overall limit per beneficiary, and contributions permitted until the end of the year the beneficiary turns 59. Employment and Social Development Canada repeats the same figure on its contributions page. Once the lifetime limit is reached, the plan stops accepting contributions entirely.
Two conditions travel with every deposit. The beneficiary has to be a resident of Canada when the plan is opened and when each contribution is made, and anyone other than the holder needs the holder's written permission to contribute. Both come from the CRA's eligibility and contributions page. A grandparent who wires money without that permission is not making a valid contribution.
| Limit | Amount | When it stops |
|---|---|---|
| Lifetime contributions | $200,000 | December 31 of the year the beneficiary turns 59 |
| Annual contributions | No limit | Not applicable, only the lifetime cap applies |
| Canada Disability Savings Grant | $3,500 per year, $70,000 lifetime | December 31 of the year the beneficiary turns 49 |
| Canada Disability Savings Bond | $1,000 per year, $20,000 lifetime | December 31 of the year the beneficiary turns 49 |
| Grant paid in a single year with carry forward | $10,500 | Applies in every year grants are still payable |
| Bond paid in the year a plan opens with carry forward | $11,000 | Ten past years plus the current year |
Is there an annual RDSP contribution limit?
No. You can contribute any amount at any point in the year until the $200,000 lifetime cap is reached. What changes with the calendar is the grant, not the contribution room. Only part of what you deposit attracts matching money, and unused grant and bond entitlement may carry forward for up to 10 years.
This is the difference that costs families the most. An RRSP or a TFSA carries unused room forward automatically. An RDSP does not carry forward contribution room, because there is no annual room to carry. What carries forward is the entitlement to grant and bond, and only for beneficiaries who were approved for the disability tax credit in those past years. A year without a contribution is not a year of lost contribution space. It can still be a year of lost grant.
If the RDSP is new to you, the overview of the plan sets out how the pieces fit together before you decide on a deposit schedule.
How much should you contribute to get the full grant?
For most families the answer is $1,500 a year. Below the income threshold, the first $500 is matched three to one and the next $1,000 is matched two to one, which produces the $3,500 annual maximum. Above the threshold the match is one to one on the first $1,000.
ESDC publishes the thresholds each year on its grants and bonds page. The rates are set by the family income reported two years earlier, so entitlement for 2026 is calculated on the 2024 tax return. The thresholds are indexed annually by the CRA, which is why they shift slightly every January and why last year's plan should be rechecked rather than repeated.
| Family income | Match on the first $500 | Match on the next $1,000 | Contribution for the maximum | Maximum grant |
|---|---|---|---|---|
| $117,045 or less | $3 for every $1 | $2 for every $1 | $1,500 | $3,500 |
| More than $117,045 | $1 for every $1 on the first $1,000 | $1,000 | $1,000 | |
ESDC gives worked examples on the same page. A contribution of $1,200 at a family income of $60,000 produces $2,900 in grant, being $1,500 on the first $500 and $1,400 on the remaining $700. A contribution of $2,000 at a family income of $80,000 produces $3,500, and the last $500 attracts nothing. That unmatched $500 is what ESDC calls an unassisted contribution. The contribution itself is not repayable. What a withdrawal or a plan closure can trigger is repayment of grants and bonds paid into the plan in the previous ten years.
The bond works on a separate scale and needs no contribution at all. It is paid once the plan is open and the bond has been applied for, provided the beneficiary is approved for the disability tax credit, resident in Canada, and the required tax returns are on file showing family income under the threshold.
| Family income | Annual bond | Contribution required |
|---|---|---|
| $38,237 or less | $1,000 | None |
| More than $38,237 and less than $58,523 | A portion of $1,000, falling as income rises | None |
| $58,523 or more | No bond | Not applicable |
Whose income counts depends on the beneficiary's age. Until December 31 of the year the beneficiary turns 18, the calculation uses the combined income of the parents or guardians. Starting in the year the beneficiary turns 19, it uses the beneficiary's own income plus a spouse's income if there is one. From the year they turn 17, the beneficiary has to file a personal return every year, and returns must be on file for at least the two previous years. Without income information on file, the grant may be limited to the 100 percent matching rate, and the bond is generally unavailable.
How does the carry forward change the right amount?
It raises the ceiling for a while. Grant and bond entitlement from the past ten disability tax credit approved years stays available, so a newly opened plan can attract far more than $3,500 in one year. The annual grant cap in that catch up period is $10,500 rather than $3,500.
ESDC's rule is that a contribution can draw grants going back as far as ten years before it was made, at the highest matching rate still available and taking the oldest outstanding entitlement within that rate first, subject to that $10,500 annual ceiling. The practical effect is that catching up takes several years. In the ESDC example, a beneficiary approved since 2015 who opens a plan in 2026 and contributes $3,500 collects $10,500, then contributes $4,000 the following year and collects $10,500 again, while the oldest year quietly drops out of the ten year window.
The bond side is simpler. Carry forward bond is paid when the plan opens and the bond has been applied for, with no contribution required, up to $11,000 in that first year, provided the beneficiary was DTC approved and resident in Canada in those years and the necessary returns are filed. That figure is $1,000 for each of up to ten past eligible years plus $1,000 for the current year. Eligibility is tested year by year against the income threshold of each year, so a family whose income moved will not collect every past year.
| Situation | Grant available in one year | Contribution that reaches it | What limits it |
|---|---|---|---|
| Plan open and fully caught up | Up to $3,500 | $1,500 at or below the income threshold | The annual grant maximum |
| New plan with ten past approved years | Up to $10,500 | Larger contributions across the year | The $10,500 annual catch up cap |
| Bond only, low family income | Up to $11,000 in the opening year | No contribution required | Ten past years plus the current year |
| Lifetime totals reached | None | Not applicable | $70,000 grant and $20,000 bond |
Every February up to and including the year the beneficiary turns 49, ESDC mails a Statement of Entitlement showing the grant available that year and the contribution needed to collect it, including carry forward. That statement is the only document that gives your number rather than the general rule. Our page on accessing government grants and bonds goes through the application side.
What changes after the year the beneficiary turns 49?
Grants and bonds stop. Contributions do not. After December 31 of the year the beneficiary turns 49, no matching grant and no bond are paid, but contributions remain allowed until the end of the year they turn 59. Money added in that window still grows tax sheltered and still counts against the $200,000 cap.
That decade changes what a contribution is for. Before 49, a deposit is mostly a way to buy grant. After 49, it is a tax sheltered savings account with no top up, and the decision looks more like any other investment choice. The plan also has to start paying out: recurring lifetime disability assistance payments must begin by December 31 of the year the beneficiary turns 60.
| Age of the beneficiary | Grant and bond | Contributions | What usually drives the decision |
|---|---|---|---|
| 0 to 49 | Payable, subject to income and carry forward | Allowed | Contribute enough to collect the full grant each year |
| 50 to 59 | Not payable | Allowed until the end of the year they turn 59 | Tax sheltered growth and the ten year repayment clock |
| 60 and over | Not payable | Not allowed | Payments must have started by the end of the year they turn 60 |
What counts toward the $200,000 limit?
Contributions and rollovers count. Grants, bonds and investment income do not. A rollover from a deceased parent's RRSP or from an RESP reduces the room left under the cap, which is why a large rollover has to be planned against contributions rather than treated as separate money. Both rollovers carry their own eligibility conditions.
ESDC gives the arithmetic directly: if $50,000 in private contributions is already in the plan, a rollover cannot exceed $150,000. No matching grant is paid on rolled over money. The CRA adds one exception on its limits page: an amount transferred directly from one RDSP to another RDSP for the same beneficiary does not count toward the $200,000. That is a transfer between plans, not a new contribution.
| Amount | Counts toward the cap | Attracts matching grant |
|---|---|---|
| Contributions from anyone with the holder's written permission | Yes | Yes, up to the annual entitlement |
| Rollover from an RRSP, RRIF, RPP, PRPP or SPP | Yes | No |
| Rollover of RESP investment income | Yes | No |
| Canada Disability Savings Grant and Bond | No | Not applicable |
| Investment income earned inside the plan | No | Not applicable |
| Direct transfer to a new RDSP for the same beneficiary | No | No |
The rollover route has its own conditions, including that the beneficiary is approved for the disability tax credit, resident in Canada, and 59 or less on December 31 of the year the rollover is made. A retirement plan rollover also requires that the beneficiary was financially dependent on the deceased parent or grandparent because of an impairment. An RESP rollover requires the education plan and the beneficiary to meet the CRA conditions attached to that transfer. Our guide to transferring funds from an RESP to an RDSP covers the education savings side in detail.
Contribution mistakes that cost real money
Three patterns show up often enough to be worth naming.
The first is front loading. Depositing $30,000 in one year at a family income below the threshold collects the same $3,500 as a $1,500 deposit, assuming no carry forward is available. The other $28,500 buys nothing extra and is locked into the repayment rules. Spread across twenty years, the same money would have collected far more.
The second is ignoring the withdrawal clock. Any grant or bond paid into the plan in the last ten years is subject to repayment at $3 for every $1 withdrawn, up to the total paid in that period. ESDC sets this out on its withdrawals page. A contribution made shortly before money is needed can therefore cost more than it earns. The ten year rule explained walks through how the holdback unwinds.
The third is treating contributions as taxable savings. They are not. The CRA is explicit in its RDSP rules: contributions are not deductible going in and are not included in the beneficiary's income coming out. The grant, the bond, the investment income and the proceeds of rollovers are what get taxed on withdrawal. That asymmetry is a large part of why the order of deposits matters. Our page on the tax treatment of RDSP withdrawals goes further.
Where to find your own numbers
The general rules on this page will not tell you what to contribute this year. Three documents will. The Statement of Entitlement that arrives each February gives the grant available and the contribution that collects it. The notice of assessment for the year two years back gives the income the calculation uses. The plan statement from the financial organization gives the contributions already made against the $200,000.
Reei builds RDSP tools for Canadian families and works through those same three documents when setting a contribution schedule. If the plan is not open yet, start with the step by step guide to opening an RDSP, because carry forward entitlement only begins converting into money once a plan exists to receive it.
