RESP-to-RDSP and RRSP-to-RDSP Rollovers: A Planning Strategy

What Is an RDSP? covers contributions, grants, and withdrawals, but not what happens when money from a completely different registered account needs to land in an RDSP instead of being taxed away first. Two specific rollovers make that possible — one from a deceased parent or grandparent's RRSP or RRIF, and one from an RESP. Both are genuinely valuable, and both are easy to miss if no one in the family knows to ask about them.

Why a rollover is worth knowing about before it's needed

Both rollovers covered here exist because, without them, money that was being saved specifically to support someone with a disability would otherwise be taxed heavily on its way to them — sometimes losing 30–50% of its value in the process. A rollover isn't a loophole; it's a deliberate exception built into the tax system for exactly this situation. The catch is that neither rollover happens automatically. Someone — an executor, a subscriber, a family member — has to know the option exists and take specific action, often within a limited window after a death or an AIP-triggering event. That makes this squarely a "raise it while everyone is healthy and thinking clearly" conversation, not a "figure it out during probate" one.

RRSP/RRIF-to-RDSP: when a parent or grandparent dies

A Registered Retirement Savings Plan (RRSP) or RRIF is normally taxed as income in full on the deceased's final tax return in the year they die — often at a significant combined rate, since it's added on top of whatever other income they had that year. There's an exception when the beneficiary is a financially dependent, infirm child or grandchild.

The conditions

• The deceased was the beneficiary's parent or grandparent.
• The RDSP beneficiary is the deceased's child or grandchild.
• The beneficiary is approved for the Disability Tax Credit (DTC) — the same gate that applies to opening an RDSP at all, covered in RDSP Eligibility and the Disability Tax Credit.
• The beneficiary was financially dependent on the deceased, by reason of a mental or physical infirmity, at the time of death.

That last condition is a facts-and-circumstances test, not a fixed dollar cutoff. The CRA generally presumes a child wasn't financially dependent if their own income for the year before the death exceeded a certain combined threshold (built from the basic personal amount plus the disability amount), but that presumption can be overturned either way depending on the full picture — living arrangements, actual support provided, and more. This is genuinely worth confirming directly with the CRA or a tax professional on the specific facts, rather than assuming either outcome from a rough income comparison.

What the rollover actually does

Instead of the RRSP or RRIF being taxed in full on the deceased's final return, the proceeds — up to the beneficiary's available RDSP contribution room — transfer directly into the beneficiary's RDSP, tax-deferred. No tax is owed at the time of the rollover. Tax is deferred until the money is eventually withdrawn from the RDSP, at which point it's taxed the same way other RDSP growth and grant money is: generally as income to the beneficiary, often at a much lower rate than the deceased's own marginal rate would have applied.

Two tradeoffs come with that benefit:

• It uses up RDSP contribution room. The rolled-over amount counts against the same $200,000 lifetime limit that applies to regular contributions — a large rollover can use up most or all of a beneficiary's remaining room.
• It doesn't attract CDSG matching. The Canada Disability Savings Grant matches contributions; a rollover isn't treated as a grant-eligible contribution for that purpose. The Canada Disability Savings Bond isn't affected either way, since it's paid based on the beneficiary's own family income rather than tied to any contribution at all.

A family navigating this

Priya's father, DTC-eligible-adjacent in his own right but the RRSP holder in this scenario, dies with a $150,000 RRIF. Priya, his adult daughter, has a severe and prolonged disability, is DTC-eligible, and was financially dependent on him for support. Without a rollover, that $150,000 would be added to her father's income on his final return, taxed at a combined federal-provincial rate that could easily claim $50,000–$65,000 of it, depending on his other income that year — leaving meaningfully less than $150,000 for Priya.

RESP-to-RDSP: when a beneficiary can't pursue post-secondary education

RESPs are built around funding post-secondary education, and money that isn't used that way — the Accumulated Income Payment (AIP), meaning the account's investment growth — normally comes with real tax friction if it's paid out to the subscriber instead: it's taxed as the subscriber's income, plus an additional 20% tax on top, and any remaining CESG or CLB still in the account is repaid to the government.

There's a specific exception for a beneficiary who has a severe and prolonged mental impairment that reasonably prevents them from pursuing post-secondary education. In that situation — and in a couple of other, less common situations involving long-standing RESPs where no beneficiary is pursuing further education — the AIP can instead roll into that same person's RDSP.

What rolls, and what doesn't

Only the accumulated income portion rolls over — not the original contributions (which the subscriber can withdraw separately, tax-free, since they were already after-tax money) and not any CESG, CLB, or other grant money still in the RESP, which is repaid to the government regardless of whether a rollover happens.

The rollover itself:

• Avoids both the regular income tax and the 20% additional tax that would otherwise apply to that AIP.
• Uses up the beneficiary's RDSP contribution room, against the same $200,000 lifetime limit.
• Doesn't attract CDSG matching, the same as the RRSP/RRIF rollover.
• Requires the RESP beneficiary and the RDSP beneficiary to be the same person — this isn't a way to redirect one child's unused RESP toward a different family member's RDSP.

A worked example

An RESP has grown to include $40,000 of accumulated income for a beneficiary who, due to a severe and prolonged mental impairment, won't be pursuing post-secondary education. Paid out as a normal AIP to the subscriber, that $40,000 would face regular income tax plus the 20% additional tax — commonly claiming somewhere close to half of it, depending on the subscriber's other income that year.

Common mistakes

• Assuming either rollover happens automatically. Both require specific CRA forms (RC4625 for RRSP/RRIF, RC435 for RESP) filed by the issuer or promoter — no one arranges this without someone actively requesting it.
• Not checking available RDSP contribution room before counting on a rollover. A large rollover can use up most of the $200,000 lifetime limit, leaving little room for future CDSG/CDSB-eligible contributions.
• Expecting CDSG matching on the rolled-over amount. Neither rollover attracts the grant — only contributions made separately, after the rollover, are grant-eligible.
• Waiting until after a death or an AIP-triggering event to learn these options exist. Both have real conditions and deadlines that are far easier to plan around in advance than to scramble to meet afterward.
• Assuming the financial-dependency test for the RRSP/RRIF rollover is a simple income cutoff. It's a facts-and-circumstances test with a rebuttable presumption, not a hard line — worth confirming directly rather than assuming disqualification based on income alone.

This article is general financial education, not personalized financial, legal, or tax advice. Eligibility for either rollover depends on specific facts — the financial-dependency test, DTC status, available contribution room, and account history all vary by family — confirm your own situation with the CRA, the relevant plan issuer or promoter, or a qualified tax professional before relying on either rollover in an estate or education plan.

What to do next

If a family member holds a meaningful RRSP or RRIF and has a DTC-eligible child or grandchild who may be financially dependent on them, or if an RESP beneficiary has a disability that may prevent post-secondary education, raising these rollovers with an estate or tax professional now — while there's time to plan — is far better than discovering them during probate or an AIP deadline.
