The interaction between the DTC and the RDSP

The disability tax credit and the Registered Disability Savings Plan are usually described as two separate programs. In practice, the credit is the condition that lets the plan start. Without DTC approval, a beneficiary cannot open a new RDSP and grant or bond payments cannot be considered. Approval is necessary, but it does not by itself produce a payment.

That dependency runs deeper than a single application. Approval sets the age clocks, decides how many past years of grant and bond you can still claim, and determines what happens to the plan years later if the Canada Revenue Agency decides the impairment no longer meets the criteria.

This page traces the credit through the whole life of a plan rather than treating it as a form to be filed once. If you only need the plan side of the test, our page on RDSP eligibility requirements covers the other conditions in more detail.

Why does an RDSP depend on the disability tax credit?

The Canada Revenue Agency defines an RDSP as a savings plan intended to help an individual who is approved to receive the disability tax credit. Approval is a condition of becoming a beneficiary, alongside a valid social insurance number, Canadian residency when the plan is entered into, and being under the age of 60.

Approval is not a self-assessment. A medical practitioner certifies on the T2201 that the individual has a severe and prolonged impairment in physical or mental functions, and the Canada Revenue Agency then approves or refuses. Your financial institution notifies the federal government when a plan is opened, and the agency verifies both the credit and residency before any grant or bond is issued.

The eligibility test itself has three routes. A marked restriction in one of the listed categories, significant limitations in two or more categories whose combined effect is equivalent to a marked restriction, or life-sustaining therapy to support a vital function.

The categories are walking, mental functions, dressing, feeding, eliminating, hearing, speaking and vision, plus life-sustaining therapy on its own. The tests are measured against a person of similar age without the impairment, and they are applied even when appropriate therapy, medication and devices are being used.

The transfer exception in the table is worth reading twice. When a beneficiary moves an existing RDSP to a new issuer, the Canada Revenue Agency does not retest approval and the age 59 ceiling does not apply. A plan that already exists can therefore move even if the beneficiary would no longer qualify to open a new one.

What does DTC approval unlock beyond the plan itself?

Approval is the key to more than one door. It makes a plan possible and makes the beneficiary eligible to be considered for the Canada Disability Savings Grant and Bond, carry-forward entitlements and the Canada Disability Benefit. Payment still depends on the plan or application, contributions for grant, filed returns, income, age and the rules of each program.

Carry forward is where retroactive approval matters. A year without DTC approval remains unavailable unless the Canada Revenue Agency later approves the credit retroactively. Even then, the year must fall inside the rolling ten-year window and meet the other eligibility rules. An application for the grant or bond is still required, and grant payments still require contributions.

The catch up is capped. While you claim past years, the maximum grant paid in one year is $10,500, and a contribution can attract grant going back as far as ten years before it was made. Bond is different: when a plan opens, up to $11,000 can be available for eligible past years and the current year. CRA must have approved each year later claimed, subject to the rolling window and other rules.

Two numbers set the rates for 2026, and both are based on the family income reported two years earlier, so a 2026 entitlement uses the 2024 return. Full bond is paid where family income is less than or equal to $38,237, a partial bond is paid above that and below $58,523, and no bond is paid at $58,523 or more. Our page on accessing grants and bonds works through the matching rates.

The Canada Disability Benefit is the newest item on that list and the one most likely to change a household's arithmetic. It requires approval for the credit, an age between 18 and 64, Canadian residency for tax purposes and a filed federal return for the applicable year. Its own rules govern how income affects the amount paid.

Because a single approval carries all of these, the value of an application is much larger than the credit line on a tax return. A family weighing whether the paperwork is worth the effort should count the plan, the grant, the bond, the carry forward and the federal benefit together rather than only the tax saving.

What happens to the RDSP if DTC approval ends?

Since 2021 the holder has a choice rather than an obligation. If the beneficiary is no longer approved for the credit, the plan can be closed or kept open. Keeping it open freezes new money going in but does not force repayment of the grants and bonds already inside the plan.

The last row is the one that surprises people. Before the year the beneficiary turns 60, a withdrawal made while approval is lost triggers repayment of grants and bonds paid into the plan in the ten years before the beneficiary lost approval, rather than the ten years before the withdrawal. The reference point moves.

Employment and Social Development Canada adds an age adjustment for beneficiaries between 50 and 59 who lost approval before the year they turned 50. In that case the ten year lookback shrinks by one year for each year the beneficiary is over 50, so in the year they turn 51 the window covers nine years rather than ten.

None of this is a penalty for losing the credit. It is the same three to one repayment machinery that applies to any early withdrawal, measured from a different date. Our page on the ten year rule sets out how that repayment is calculated.

How do you protect a plan across DTC renewals?

For an approval that is time-limited, track the end date and start renewal early. An approval without an end date does not create a renewal deadline. If approval lapses, contributions, grants and bonds stop. Each unapproved year remains unavailable unless CRA later approves the DTC retroactively, subject to the rolling ten-year window and other eligibility rules.

The mechanics behind those thresholds are published by Employment and Social Development Canada, which also confirms that grant is paid until December 31 of the year the beneficiary turns 49 and that, in a year with no carry-forward room, contributions above the amount needed to attract the maximum grant earn nothing extra.

Filing returns is the step most often skipped and the one that quietly costs the most. From the year the beneficiary turns 19, grant and bond amounts are calculated on their own income plus a spouse's income, and they must have filed for at least the two previous years for the correct amount to be paid.

If approval is regained, the plan operates normally again and contributions can resume. Entitlement for a year without approval remains unavailable unless the Canada Revenue Agency later grants retroactive approval, because carry forward counts approved years within the applicable window. That asymmetry is why a renewal handled early is worth more than a successful appeal handled late.

Two practical notes to close. Withdrawing from the plan is a separate decision with its own consequences, covered on our page about the impact of withdrawals on other benefits, and opening the plan itself is a short process once approval is in hand, set out in our step by step guide.
