Registered Disability Savings Plan (RDSP): A Strategic Guide for High-Net-Worth Families

Registered Disability Savings Plan (RDSP) guide for high-net-worth families: DTC eligibility, $200,000 lifetime room, and up to $90,000 in federal grants/bonds. Learn the key tax-planning moves—timing deposits, meeting age cut-offs, income thresholds, and preserving ODSP benefits.

The Registered Disability Savings Plan (RDSP) is one of Canada’s most powerful but underutilized tax-sheltered vehicles designed to secure the long-term financial well-being of individuals with disabilities. While RDSPs are available to all eligible Canadians, high-net-worth (HNW) families in particular stand to benefit significantly from proper RDSP planning. This guide outlines the key features, eligibility requirements, contribution rules, and strategic planning opportunities available to HNW families in Mississauga & GTA or other parts of Canada.

An RDSP is the only Canadian registered plan that offers up to $90,000 in federal contributions—$70,000 in matching grants plus $20,000 in bonds—on top of tax-sheltered growth.

What is an RDSP?

An RDSP is a government-registered savings plan intended to help parents and others save for the long-term financial security of a person who is eligible for the Disability Tax Credit (DTC). It allows for tax-deferred investment growth and, in many cases, access to substantial government contributions.

Who is Eligible?

To open or be a beneficiary of an RDSP, the individual must:

Be eligible for the Disability Tax Credit (DTC) under the Income Tax Act
Be a Canadian resident with a valid Social Insurance Number (SIN)
Be 59 years old or younger at the end of the year of contribution

Plan Holder:

For minors: a parent, guardian, or legal representative
For adults: the individual themselves if legally competent, or a qualifying family member, legal guardian, or someone authorized under provincial law

Contributions: How Much and By Whom?

Lifetime contribution limit: $200,000. Contributions are permitted until the end of the year in which the beneficiary turns 59.
No annual contribution limit
Contributions are not tax-deductible, but income grows tax-deferred
Anyone can contribute with the written permission of the plan holder
Amounts directly transferred from one beneficiary’s RDSP to another RDSP for the same beneficiary do not count toward the $200,000 overall contribution limit.

Government Grants and Bonds

1. Canada Disability Savings Grant (CDSG)

Matching grants up to 300%, depending on family income
Maximum of $3,500/year, with a lifetime limit of $70,000

Canada Disability Savings Grant (CDSG) – how it is calculated

The CDSG provides matching government contributions of 300%, 200%, or 100%, depending on the beneficiary’s adjusted family net income and the amount contributed to the RDSP.

From birth to age 18: Income is based on the parents’ or guardians’ income used for the Canada Child Benefit (CCB).
From age 19 onward: Income is based on the beneficiary’s income, plus that of their spouse or partner, if applicable.
If in institutional care: Income is based on the Children’s Special Allowance received by the institution.

Grant Amounts Based on Adjusted Family Net Income

The beneficiary’s adjusted family net income thresholds are indexed annually to inflation. The following thresholds are for 2025:

If income is $114,750 or less:
- $3 for every $1 on the first $500 = $1,500
- $2 for every $1 on the next $1,000 = $2,000
- Maximum annual grant: $3,500
If income is more than $114,750:
- $1 for every $1 on the first $1,000 = $1,000
- Maximum annual grant: $1,000

Lower-income beneficiaries receive enhanced matching to help grow long-term savings. Carry forward of unused grant entitlements is available for up to 10 years.

Canada Disability Savings Bond (CDSB)

The Canada Disability Savings Bond is a government contribution of up to $1,000 per year paid directly into an RDSP for low-income Canadians with disabilities. No personal contributions are required to receive the bond.

Lifetime limit: $20,000
Age limit: Bonds can be paid until December 31 of the year the beneficiary turns 49

2025 Income Thresholds:

$37,487 or less → Full bond of $1,000
$37,487 – $57,375→ Partial bond (calculated by formula in the Act)
Over $57,375→ No bond paid

To qualify, the beneficiary (or their parents/guardians if under 18) must have filed income tax returns for the past two years and continue filing annually.

For beneficiaries under age 18, bond eligibility is based on parental income. Starting at age 17, the beneficiary must file their own tax returns to continue receiving accurate bond entitlements at age 19 and beyond.

Tax Treatment and Withdrawals

Investment income and government contributions grow tax-free until withdrawal
Withdrawals consist of a mix of personal contributions (non-taxable) and grant/bond/investment income (taxable to the beneficiary)
Two types of withdrawals:
- Disability Assistance Payments (DAPs): Lump sums
- Lifetime Disability Assistance Payments (LDAPs): Regular annual payments starting no later than age 60

Withdrawals may trigger repayment of government grants/bonds if made within 10 years of receipt.

Disability Assistance Payments (DAPs) – Mechanics

DAPs are lump-sum withdrawals from an RDSP that can be made at any time and for any purpose. There are no restrictions on how the funds must be used — they can support daily living expenses, disability-related costs, or other personal needs of the beneficiary. Unlike Lifetime Disability Assistance Payments (LDAPs), DAPs are not subject to an annual schedule and may be requested as needed.

However, if the RDSP is classified as a “primarily government-assisted plan” — meaning it has received more in government grants and bonds than personal contributions — DAPs are subject to a withdrawal limit. In that case, the maximum annual DAP is the greater of:

The annual LDAP minimum, or
10% of the RDSP’s fair market value at the beginning of the year.

Tax-wise, only the government contributions and investment earnings portion of a DAP is taxable, and it is taxed in the hands of the beneficiary. Personal contributions are always non-taxable when withdrawn. Additionally, if a DAP is made within 10 years of receiving a grant or bond, the plan must repay $3 of grants/bonds for every $1 withdrawn, as part of the federal 10-year repayment rule.

DAPs offer flexibility but must be carefully planned to avoid unnecessary tax or repayment of government incentives

Lifetime Disability Assistance Payments (LDAPs): Mechanics

Start no later than Dec 31 of the year the beneficiary turns 60 and pay at least once a year for life.
Minimum each year = CRA formula (~4-10 % of the Jan 1 balance); if government money still exceeds private deposits, the maximum is the higher of that formula or 10 % of the account.
Every payment is taxable to the beneficiary, and any withdrawal within 10 years of a grant/bond repays it at $3-for-$1.
A doctor-certified life expectancy under five years lifts both the annual minimum and maximum caps.

RDSP Rules When DTC Approval Is Lost

Since 2021, if a beneficiary loses eligibility for the Disability Tax Credit (DTC), the RDSP does not need to be closed. The plan holder may choose to keep it open, with the following conditions:

Withdrawals are still allowed
No new contributions can be made
No new grants or bonds will be paid
Rollovers from deceased parents’/grandparents’
RRSP/RRIF/RPP/PRPP/SPP are still permitted (must be done within 5 years of DTC loss)
No automatic repayment of existing grants and bonds is required just because DTC is lost
Withdrawals made before age 60 may trigger repayment of grants/bonds received in the 10 years before DTC loss
If DTC is later re-approved, the RDSP returns to full functionality

What happens if the beneficiary dies

The RDSP must be closed and all amounts remaining in the plan must be paid out to the beneficiary’s estate by December 31st of the year following the calendar year in which the beneficiary dies. Any funds remaining in the RDSP, after any required repayment of government grants and bonds, will be paid to the estate. If a DAP had been made and the beneficiary is deceased, the taxable portion of the DAP must be included in the income of the beneficiary’s estate in the tax year in which the payment is made.

Strategic Planning for High-Net-Worth Families

High-net-worth families can leverage RDSPs as part of a broader financial and estate plan:

Use of Trusts:
1. Henson Trusts or other discretionary trusts can distribute funds to the RDSP without disqualifying the beneficiary from provincial disability benefits (e.g., ODSP).
1. Testamentary trusts can be structured to make annual contributions to an RDSP over time.
Estate Planning:
1. Designate RDSP beneficiaries in wills
1. Coordinate with other registered plans (RRSP, TFSA, RESP) to optimize tax and income outcomes
1. Avoid probate by using successor holder provisions
Income Splitting Opportunities:
1. Since taxable withdrawals are taxed in the hands of the beneficiary (who may have little to no income), this may offer significant tax deferral and income splitting for the family
Long-Term Funding Strategy:
1. For families nearing the $200,000 contribution cap, investing early maximizes compound growth
1. Using corporate funds via shareholder income can be a tax-effective way to fund RDSP contributions
You still get a 100 % match.
1. Even if the household earns well above the threshold, contributing $1,000 will trigger a guaranteed $1,000 grant each year—an immediate 100 % return that no other account offers.
Income “drops” after age 19.
1. If the beneficiary has little personal income, grant rates can jump back to 300 %/200 % even though the parents are high-income earners. Filing timely tax returns for the beneficiary is critical to lock in the higher match.
Bond is different.
1. The Canada Disability Savings Bond ($1,000 a year, no contribution required) begins to phase out at $37,487 and disappears entirely above $57,375 AFNI for 2025. High-income families should not rely on the bond.

Provincial Considerations and ODSP

In Ontario, RDSPs do not affect eligibility for the Ontario Disability Support Program (ODSP), even for large balances or withdrawals. This makes RDSPs especially valuable, as they allow for asset accumulation without jeopardizing essential benefits.

Common Pitfalls to Avoid

Failing to apply for the Disability Tax Credit (DTC)
Withdrawing funds too early and triggering repayment of grants and bonds
Not coordinating with a professional accountant or estate planner, especially when trusts and cross-border issues are involved
