RDSP vs RRSP: What’s the Difference?

A Registered Retirement Savings Plan (RRSP) asks how much you earned last year. A Registered Disability Savings Plan (RDSP) asks whether a doctor has signed a specific government form. That single contrast explains most of what separates these two accounts, since one is built around income and the other around eligibility for the Disability Tax Credit (DTC), and almost every other difference between them flows from that starting point.

An RDSP and an RRSP are both tax-deferred registered accounts, but they serve entirely different purposes. An RRSP is available to any Canadian with earned income and rewards contributions with an immediate tax deduction. An RDSP is restricted to DTC-approved beneficiaries, offers no deduction at all, and instead attracts government matching grants and bonds worth up to $90,000 over a lifetime.

What Each Account Actually Requires You to Be

Opening an RRSP requires nothing more than being a Canadian resident under 71 with earned income from the prior year, since that income is what generates contribution room in the first place. There’s no disability requirement, no application process beyond opening the account itself, and no approval needed from anyone outside the financial institution.

An RDSP works backward from that. The beneficiary has to be approved for the Disability Tax Credit before the account can even be opened, a process that runs through a medical practitioner and the Canada Revenue Agency (CRA) rather than through the bank. Earned income plays no role in RDSP eligibility at all. A beneficiary with no income whatsoever can still have an RDSP opened on their behalf, since contributions can come from a parent, grandparent, or anyone else with the plan holder’s written permission.

How Much You Can Put in Each Year

RRSP room is a moving target tied to income. For 2026, the maximum new room any individual can generate is $33,810, based on 18% of 2025 earned income, a figure that only applies in full to someone who earned about $187,833 or more the prior year. Unused room carries forward indefinitely, so a low-income year doesn’t erase the opportunity, it just delays it.

An RDSP works nothing like this. There’s no annual limit at all, and no connection to anyone’s income for the purpose of how much can go in. The only constraint is a $200,000 lifetime ceiling per beneficiary, which can be reached in a single large deposit if the family has the means, or spread across decades in small amounts.

The Deduction Difference

Every dollar contributed to an RRSP reduces the contributor’s taxable income for that year, dollar for dollar, which is the entire mechanism that makes RRSPs attractive to higher earners in particular. Contribute $10,000 at a high marginal rate and the refund alone can be worth several thousand dollars back at tax time.

An RDSP contribution generates nothing comparable. The full mechanics of why that’s true, and what a contributor gets instead, are worth reading in detail elsewhere on this site, but the short version is that the incentive structure runs on a completely different timeline. An RRSP rewards the contributor immediately through a tax deduction. An RDSP rewards the beneficiary later, through government money that has nothing to do with anyone’s tax return.

The Government Matching That RRSP Doesn’t Have

This is the piece that actually makes the RDSP worth using despite the missing deduction. The Canada Disability Savings Grant matches personal contributions at up to 300%, worth up to $3,500 a year and $70,000 over a lifetime, and the Canada Disability Savings Bond adds up to $1,000 a year with no contribution required at all for lower-income families, worth another $20,000 lifetime. An RRSP offers nothing structurally similar. The government’s only involvement in an RRSP is the tax deduction itself, not a matching contribution added on top of what you put in.

What Happens at Withdrawal

An RRSP withdrawal is taxed entirely as ordinary income to whoever takes the money out, and it’s taxed to the same person who claimed the deduction when they contributed. There’s no splitting the withdrawal into pieces. The whole amount counts as income in the year it’s withdrawn.

An RDSP withdrawal works differently in a way that matters most when the contributor and the beneficiary are different people, which is common given how often parents or grandparents fund these accounts. Only the grant, bond, and investment growth portion of an RDSP withdrawal is taxable, and it’s taxed to the beneficiary specifically, never the contributor, regardless of who actually put the money in. A grandparent who contributed $15,000 over several years never reports a dollar of that on their own return, at contribution or at withdrawal.

The Age Timelines Compared

Milestone	RRSP	RDSP
Contributions can be made until	End of year turning 71	End of year turning 59
Government incentive stops	Never applies	End of year turning 49 (grant and bond)
Mandatory withdrawals begin	Year turning 71 (conversion to a Registered Retirement Income Fund)	Year turning 60 (LDAP payments)

The RDSP’s timeline compresses everything into an earlier window relative to the RRSP, with the contribution cutoff sitting 12 years earlier and the mandatory withdrawal age sitting 11 years earlier than their RRSP equivalents.

The RRSP to RDSP Rollover

Here’s a connection between these two accounts that surprises a lot of people. When an RRSP or RRIF annuitant dies, Canada.ca’s own rules on transferring these amounts allow the proceeds to roll over, tax-deferred, into the RDSP of a financially dependent child or grandchild who’s eligible for the DTC because of a physical or mental impairment. No tax gets withheld on that rollover payment at all.

This isn’t a minor technicality. Without this rule, a deceased parent’s RRSP would normally be fully included as income on their final tax return, creating a potentially large tax bill for the estate in the year of death. Rolling it into the child’s RDSP instead defers that tax entirely, and the money only becomes taxable much later, and only to the child, as it’s eventually withdrawn from the RDSP. The rolled-over amount does count against the beneficiary’s $200,000 lifetime RDSP contribution limit, so a very large RRSP can’t simply disappear into an RDSP without regard to that ceiling, but it’s a useful estate-planning tool for exactly the families this account is built for.

Can You Have Both

Yes, and there’s no conflict between them. A person can be the beneficiary of an RDSP funded by their family while also maintaining their own separate RRSP built from their own earned income, if they have any. The two accounts don’t share contribution room, don’t affect each other’s limits, and serve entirely different functions, one for disability-related long-term savings with government matching, the other for retirement savings with an upfront tax deduction. Beyond the specific death-rollover mechanic, they simply run in parallel.

Mistakes People Commonly Make

The most common one is assuming an RDSP contribution works like an RRSP contribution and expecting a tax refund that never arrives, since the entire benefit structure of an RDSP sits on the government-matching side rather than the deduction side. The second is a family withdrawing from an RRSP to fund an RDSP contribution without accounting for the tax hit that RRSP withdrawal itself triggers, which can quietly erode a meaningful chunk of the money before it ever reaches the RDSP. And the third is not knowing the rollover option exists at all, leading a family to let a deceased parent’s RRSP get taxed in full on the final return when a tax-deferred transfer into a dependent child’s RDSP was available the whole time.

What to Do Next

If you’re weighing which account to prioritize for a family member who’s DTC-eligible, the RDSP’s government matching almost always outweighs what an RRSP could offer for the same dollars, given the 300% match available at lower incomes. If you’re the parent or grandparent of a DTC-eligible child or grandchild and haven’t reviewed your estate plan with this rollover in mind, that’s worth a conversation with whoever handles your will, since the difference between a taxed RRSP and a rolled-over one can be substantial. And if you’re unsure whether a specific family member currently qualifies to receive a rollover, confirming their DTC status now, rather than after a death in the family, avoids losing the option when timing matters most.

A Few More Questions Worth Answering

Can RRSP contribution room be used to open an RDSP? No. The two accounts don’t share contribution room, and RDSP contribution room isn’t calculated from earned income at all. The only connection between them is the specific death-rollover rule covered above.

Does contributing to an RDSP reduce RRSP room? No. These are entirely separate systems, and putting money into one has no effect on the contribution limits or deduction room available in the other.

Is the RRSP-to-RDSP rollover available for any relative, not just a child or grandchild? No. The rollover is specifically limited to a financially dependent child or grandchild of the deceased annuitant who’s DTC-eligible because of an impairment, and it isn’t available for other relatives such as siblings, nieces, or nephews, a distinction CRA’s death of a RRIF annuitant page confirms explicitly.
