Detailed Guide Coming Soon
We're working on a comprehensive educational guide for the Canada Registered Disability Savings Plan. Check back soon for step-by-step explanations, formulas, real-world examples, and expert tips.
The Registered Disability Savings Plan (RDSP) is a long-term savings plan specifically designed for Canadians who qualify for the Disability Tax Credit (DTC). It is designed to help people with disabilities and their families save for long-term financial security. The Canadian government provides generous matching through two programs: the Canada Disability Savings Grant (CDSG) and the Canada Disability Savings Bond (CDSB). The CDSG matches contributions at a rate that depends on family income — for families with net income up to $106,717 (2024), the government contributes 300% on the first $500 contributed (maximum $1,500) and 200% on the next $1,000 (maximum $2,000), for a maximum annual CDSG of $3,500. For families above this threshold, the matching rate is 100% on the first $1,000 (maximum $1,000 CDSG). The Canada Disability Savings Bond provides up to $1,000/year to low-income individuals (with family net income below $53,359 in 2024) without requiring any contributions. Contributions to an RDSP are not tax-deductible, but growth inside the account is tax-sheltered and withdrawals are taxed in the beneficiary's hands. The lifetime contribution limit is $200,000. RDSP withdrawals include both the government grant/bond portions (fully taxable) and the contribution and growth portions. A 10-year holding rule applies to grants and bonds before they can be withdrawn without repayment.
CDSG = 300% × min(contribution, $500) + 200% × min(contribution - $500, $1,000) [for income ≤ $106,717]; Max CDSG = $3,500/year; CDSB = $1,000/year [for income ≤ $53,359]; Lifetime CDSG max = $70,000; Lifetime CDSB max = $20,000
- 1Confirm the beneficiary is approved for the Disability Tax Credit (DTC) — a signed T2201 form approved by CRA is required to open an RDSP
- 2Open an RDSP at a participating financial institution — only the beneficiary, their legal representative, or a qualifying family member can open and contribute
- 3The Canada Disability Savings Grant is automatically applied when contributions are made — no separate application needed
- 4For CDSG (income ≤ $106,717): contribute up to $1,500/year to maximize the $3,500 CDSG; for higher income, contribute $1,000 to get $1,000 CDSG
- 5The Canada Disability Savings Bond ($1,000/year) is paid automatically to beneficiaries with low family income without requiring any contribution
- 6Money inside the RDSP grows tax-free; withdrawals are taxed as income in the beneficiary's hands (grants and bonds) with contributions returned tax-free
- 7The 10-year holding period means grants and bonds paid in the last 10 years must be repaid if the RDSP is closed or the beneficiary ceases to qualify — plan accordingly
The maximum annual CDSG of $3,500 requires a contribution of $1,500.
A $1,500 contribution generates the full $3,500 CDSG — the government adds $3,500 on top of your $1,500, putting $5,000 into the RDSP in one year.
Both CDSG and CDSB apply. Total government additions = $4,500 on a $1,500 personal contribution.
At low incomes, the combination of maximum CDSG ($3,500) and the CDSB ($1,000) means the government contributes $4,500 for every $1,500 of personal savings — a 300% effective match rate on the personal contribution.
Higher income families receive 100% match on first $1,000 (max $1,000 CDSG). No CDSB applies.
Families above the lower income threshold still receive a meaningful CDSG — $1,000 on a $1,000 contribution — but do not receive the maximum $3,500 or the CDSB.
The 10-year holdback means grants paid in the most recent 10 years are subject to repayment on plan closure.
The 10-year holdback rule is designed to ensure the RDSP is truly a long-term savings plan. Any grants paid in the 10 years preceding closure must be repaid, regardless of investment growth.

Rollover from RRSP/RRIF
{'title': 'Rollover from RRSP/RRIF', 'body': "Under the RRSP/RRIF rollover provision, up to $200,000 can be transferred from a deceased parent's or grandparent's RRSP or RRIF directly to a beneficiary's RDSP on a tax-deferred basis, subject to conditions. This can substantially accelerate RDSP savings."} When encountering this scenario in canada registered disability calculations, users should verify that their input values fall within the expected range for the formula to produce meaningful results. Out-of-range inputs can lead to mathematically valid but practically meaningless outputs that do not reflect real-world conditions.
Assistive Technologies and Catch-Up Contributions
{'title': 'Assistive Technologies and Catch-Up Contributions', 'body': 'Beneficiaries who could not contribute in earlier years (due to lack of DTC approval or other factors) can make catch-up contributions. CRA will pay CDSG for missed years going back 10 years, limited to the annual maximums and subject to current family income thresholds.'}
Beneficiary Becomes a Non-Resident
{'title': 'Beneficiary Becomes a Non-Resident', 'body': 'If the RDSP beneficiary ceases to be a Canadian resident, the RDSP must generally be closed, triggering the 10-year holdback repayment. There is a planning opportunity to maximize withdrawals before departing Canada to minimize the holdback impact.'} In the context of canada registered disability, this special case requires careful interpretation because standard assumptions may not hold. Users should cross-reference results with domain expertise and consider consulting additional references or tools to validate the output under these atypical conditions.
| Income Level | CDSG Rate | Max Annual CDSG | Annual CDSB |
|---|---|---|---|
| Family net income ≤ $53,359 | 300% on first $500 + 200% on next $1,000 | $3,500 | $1,000 |

Who is eligible for an RDSP?
To be eligible, the beneficiary must be a Canadian resident, under 60 years of age when contributions are made, have a valid Social Insurance Number, and be approved for the Disability Tax Credit (DTC). The DTC requires a completed T2201 certified by a medical practitioner and approved by CRA. This is an important consideration when working with canada registered disability calculations in practical applications.
What is the lifetime contribution limit?
The lifetime contribution limit is $200,000 per beneficiary. There is no annual contribution limit, but CDSG and CDSB have annual maximums ($3,500 and $1,000 respectively). Contributions in excess of $200,000 attract a 1% per month penalty tax. In practice, this concept is central to canada registered disability because it determines the core relationship between the input variables. Understanding this helps users interpret results more accurately and apply them to real-world scenarios in their specific context.
Are RDSP contributions tax-deductible?
No. Unlike RRSP contributions, RDSP contributions are not tax-deductible. However, the investment grows tax-free inside the plan, and only the grants, bonds, and investment income are taxable when withdrawn — contributions are returned tax-free. This is an important consideration when working with canada registered disability calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied.
What is the 10-year holdback rule?
Grants and bonds paid in the 10 years before an RDSP is closed must be repaid to the government. This includes situations where the beneficiary dies, ceases to qualify for the DTC, or the plan is closed. The 10-year rule is calculated on a rolling basis. In practice, this concept is central to canada registered disability because it determines the core relationship between the input variables.
Can a beneficiary have more than one RDSP?
No. Only one RDSP can be open for any individual beneficiary at a time. However, an RDSP can be transferred from one issuer to another. This is an important consideration when working with canada registered disability calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
What happens if the beneficiary dies?
If the beneficiary dies, the RDSP must be closed. Grants and bonds received in the last 10 years must be repaid. Remaining funds are paid to the estate as taxable income. There is no ability to transfer an RDSP to another beneficiary. This is an important consideration when working with canada registered disability calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied.
Can unused CDSG and CDSB room be carried forward?
Yes. Unused CDSG and CDSB room carries forward for 10 years. This means if you did not contribute in some years, you may be able to make catch-up contributions in later years to receive the grants for those missed years (subject to annual limits on grant and bond payments). This is an important consideration when working with canada registered disability calculations in practical applications.
What are the withdrawal rules for an RDSP?
Withdrawals can be made as a Lifetime Disability Assistance Payment (LDAP) — regular annual payments — or a Disability Assistance Payment (DAP) at any time. The 10-year holdback applies to plan closure (not individual withdrawals). LDAP must begin by age 60. This is an important consideration when working with canada registered disability calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied.
Pro Tip
If a family member qualifies for the DTC, open an RDSP immediately — even with no contributions. The Canada Disability Savings Bond of $1,000/year starts accumulating from the first year the plan is open, regardless of contributions (for qualifying income levels). Years of unclaimed bonds cannot be easily recovered.
Did you know?
The RDSP was introduced in 2008 as part of the Federal Budget under the Harper government. By 2023, over 250,000 RDSPs had been opened across Canada, holding over $8 billion in savings. The government has contributed over $3 billion in CDSG and CDSB grants and bonds since the program launched.
