No. Contributions to a Registered Disability Savings Plan (RDSP) are not tax deductible, unlike a Registered Retirement Savings Plan (RRSP), where every dollar contributed reduces taxable income for that year. A parent or family member contributing $5,000 to an RDSP gets no line on their tax return for it, no refund, nothing. That surprises people who assume every registered account works the same way an RRSP does, and it’s the first thing worth clearing up before anything else about how this account gets taxed makes sense.

What contributions do get in exchange is tax-deferred growth once the money is inside the plan, and a withdrawal structure that treats the original contributions as already-taxed money forever. The government matching grants and bonds, along with any investment growth the account earns, are taxed later, but only when money actually comes out, and only in the beneficiary’s hands, not the contributor’s.
What Not Deductible Actually Means for a Contributor
Whoever puts money into the RDSP, a parent, a grandparent, a family friend, gets nothing back from the Canada Revenue Agency (CRA) in the year of the contribution. There’s no deduction to claim, no tax slip generated for having contributed, and no reduction in the contributor’s own taxable income. This holds true no matter how much is contributed in a given year, since the RDSP has no annual contribution limit at all, only the $200,000 lifetime ceiling per beneficiary.
That’s a genuine structural difference from an RRSP, where the entire incentive to contribute is built around the upfront deduction. An RDSP asks a contributor to give up that immediate tax benefit in exchange for something that only pays off for the beneficiary, and only much later.
What Happens Instead, Tax-Deferred Growth
While the money sits inside the account, investment income, interest, dividends, and capital gains all compound without being taxed year to year, the same tax-deferred treatment an RRSP offers. The difference is what happens when it eventually comes out. An RRSP withdrawal gets taxed as ordinary income to whoever contributed and later withdraws it. An RDSP withdrawal splits into pieces, and each piece gets treated differently.
The Three-Part Split When Money Comes Out
Every Disability Assistance Payment or Lifetime Disability Assistance Payment (DAP or LDAP) blends three types of money together, and Canada.ca’s own explanation of withdrawals states the split plainly. The portion representing original contributions comes out completely tax-free, since that money was already taxed before it went in and never received a deduction. The portion representing the Canada Disability Savings Grant and Bond is taxable. And the portion representing investment growth and income earned inside the account is taxable as well.
All of that taxable portion lands as income in the beneficiary’s hands, not the contributor’s, regardless of who actually put the money in originally. A grandparent who contributed $20,000 over several years never sees a tax consequence from that contribution, at contribution or at withdrawal. The beneficiary does, and only on the grant, bond, and growth portion of whatever gets paid out.
Why the Tax Bill Usually Lands Softer Than People Expect
Here’s the detail that rarely makes it into a quick summary of these rules. Every RDSP beneficiary is, by definition, approved for the Disability Tax Credit (DTC), which means every RDSP beneficiary automatically qualifies for two federal non-refundable tax credits, the basic personal amount and the disability amount. The CRA’s own guidance on RDSP tax withholding confirms that issuers don’t need to withhold tax at source until the taxable portion of lump-sum payments in a year exceeds the combined value of those two credits.
For 2026, the federal basic personal amount sits at $16,452, and the federal disability amount is $10,341, for a combined threshold of $26,793. A beneficiary can receive up to that amount in taxable grant, bond, and growth payments in a single year before any tax gets withheld at source at all. That’s a meaningfully higher bar than most people assume walking into this, since the instinct is to expect RDSP withdrawals taxed the same punishing way an RRSP withdrawal would be.
The Withholding Rates If You Cross That Threshold
Past that combined credit amount, withholding applies on a tiered basis. The federal portion sits at 10% on amounts up to $5,000, 20% on the portion between $5,000 and $15,000, and 30% on anything above $15,000, with Quebec residents facing a lower federal-only component of 5%, 10%, and 15% at the same thresholds, since Quebec administers its own provincial withholding separately. These are withholding rates, meaning tax taken off at the time of payment, not necessarily the beneficiary’s final tax bill, which still depends on their total income and applicable credits when they file that year’s return.
What Happens to Rolled-Over RRSP or RESP Money
Money doesn’t only enter an RDSP as a direct contribution. Under specific circumstances, funds can roll over from a deceased parent or grandparent’s RRSP, or from an RESP, into an RDSP for an eligible beneficiary. CRA’s general RDSP rules page confirms that these rollover amounts aren’t taxed at the point they move into the RDSP, but they become part of the taxable pool once eventually withdrawn from the RDSP itself. That’s a different treatment than a straightforward cash contribution, which is never taxable on the way out, and it’s worth flagging specifically to anyone involved in estate planning that touches an RDSP.
How This Compares to an RRSP and a TFSA
| Account | Contribution Treatment | Growth While Held | Withdrawal Treatment |
|---|---|---|---|
| RDSP | Not deductible | Tax-deferred | Contributions tax-free, grant, bond, and growth taxable to beneficiary |
| RRSP | Fully deductible | Tax-deferred | Fully taxable as income to the withdrawer |
| TFSA | Not deductible | Tax-free | Entirely tax-free on withdrawal |
Laid out this way, the RDSP sits in its own category, closer in spirit to an RESP than either an RRSP or a TFSA, since both accounts tax the growth and government incentive money to the beneficiary specifically rather than the contributor, while leaving the original contributions untouched.
Mistakes People Commonly Make
The most common one is assuming an RDSP withdrawal gets hit with the same full-marginal-rate tax treatment an RRSP withdrawal does, which leads some families to avoid withdrawing money even when the beneficiary truly needs it, purely out of an inflated sense of the tax cost. Given the combined credit threshold most beneficiaries can use before any withholding even applies, that fear is often larger than the actual consequence.
The second is conflating this income tax question with the assistance holdback amount and grant repayment rules, which are a completely separate mechanism from income tax. A withdrawal can trigger grant and bond repayment to the government under the proportional rule regardless of whether any income tax is owed on that same withdrawal, and the two calculations run independently of each other. And the third is a contributing parent or grandparent expecting some kind of tax receipt or slip for their own contribution, which simply doesn’t exist for an RDSP the way it does for an RRSP.
What to Do Next
If a withdrawal is being planned, ask the provider directly what portion of that specific payment would be taxable before assuming a worst-case number, since the actual taxable share depends on how much of the account balance is contributions versus grant, bond, and growth at that point. If the beneficiary is close to the combined credit threshold for the year, timing a withdrawal to stay under it, or spreading it across two calendar years, can avoid triggering withholding altogether. And for the mechanics of how withdrawal amounts get calculated and structured in the first place, our breakdown of RDSP withdrawal rules covers that separate piece in full.
A Few More Questions Worth Answering
Does a contributing parent need to report anything on their own tax return? No. Since RDSP contributions aren’t deductible and don’t generate any tax slip for the contributor, there’s nothing to report on the contributor’s return connected to the act of contributing.
Will I get a tax slip for RDSP withdrawals? Yes. The taxable portion of DAPs and LDAPs is reported to the beneficiary on a T4A slip for the year the payment was made, which then gets included on that year’s personal tax return.
Does transferring the Disability Tax Credit to a supporting person change any of this? No. Transferring the DTC affects who can claim that credit on their own tax return, but it has no bearing on how RDSP contributions, growth, or withdrawals are taxed, since those rules are tied to the beneficiary and the plan itself, not to who claims the DTC.
