What Happens After DTC Approval: A Practical Next-Steps Guide

A Disability Tax Credit (DTC) approval letter from the CRA confirms eligibility — but it does not, on its own, automatically claim the credit, open any accounts, or trigger any of the connected benefits discussed elsewhere in this category. Approval is the foundation; what happens next determines how much of the available support actually gets accessed.

Step 1: Review the Determination Letter Carefully

The CRA’s determination letter specifies several things that matter for what comes next: which years the approval covers (including whether it includes past years retroactively), whether the approval is permanent or has an expiry date requiring renewal, and which category or categories of impairment were approved (relevant if multiple categories were claimed, as the approved categories may differ from what was originally submitted).

Step 2: File or Adjust Tax Returns for Retroactive Years

If the determination letter confirms eligibility for previous years, the next step is requesting adjustments to those years’ tax returns through the CRA’s T1 Adjustment Request process (available online through CRA My Account, or by mail). This applies whether the DTC is being claimed by the individual themselves or transferred to a supporting family member — in either case, the relevant year’s return needs to be adjusted to include the credit.

Given that retroactive claims can cover up to 10 years, and the DTC’s value compounds with related provisions (such as the Canada Caregiver Credit, which may also apply retroactively for the same years if not previously claimed), this step alone can represent a substantial refund — but only if the adjustment requests are actually filed.

Step 3: Determine Who Should Claim the Credit Going Forward

For the current and future years, determine whether the DTC-eligible individual has enough taxable income to use the credit themselves, or whether some or all of it should be transferred to a supporting family member. If circumstances have changed since the original application (income changes, changes in who provides primary support), this allocation may need to be revisited periodically — it is not necessarily a "set once" decision, particularly for families where income levels or caregiving arrangements change over time.

Step 4: Open an RDSP, If Eligible and Not Already Done

As discussed in our companion article, DTC approval is the gateway to opening a Registered Disability Savings Plan, for beneficiaries under 60. If an RDSP has not yet been opened, this is often the single highest-value next step — particularly given the carry-forward provisions for government grants and bonds, where time elapsed since DTC eligibility began may represent a diminishing (though not necessarily lost) opportunity.

Step 5: Check the Canada Caregiver Credit (If Applicable)

If a family member provides support to the DTC-approved individual and the dependency criteria are met, the Canada Caregiver Credit may be claimable by that family member — separately from any DTC transfer. As discussed in our Women & Finance article on this credit, this is commonly missed, including for past years where it could also potentially be claimed retroactively.

Step 6: Confirm the Child Disability Benefit Is Being Received (For Children)

For a DTC-approved child under 18, confirm that the Child Disability Benefit is being received as part of the family’s Canada Child Benefit payments. This should occur automatically once the DTC approval is linked to the family’s benefit account, but families should verify this on a recent Canada Child Benefit notice (which itemizes the benefit components) rather than assuming it is occurring without confirmation.

Step 7: Note the Renewal Date, If Applicable

If the approval has an expiry date (rather than being permanent), note this date and plan to begin the renewal process well in advance — ideally several months before expiry, to allow time for a new medical certification and CRA processing without a gap in eligibility. A gap between an expired approval and a renewed one can disrupt RDSP grant and bond eligibility for that period, among other effects, so avoiding gaps through proactive renewal is preferable to addressing a lapse after it occurs.

Step 8: Consider Longer-Term Planning Implications

For families where the DTC approval is for a child, or for an adult with a condition expected to be lifelong, the approval may also be relevant to longer-term planning — estate planning considerations (such as whether a Henson trust or similar structure is appropriate, as discussed in our article on caregivers of adult children), and the parent’s or caregiver’s own retirement planning, particularly if ongoing caregiving responsibilities affect their own work and savings trajectory, as discussed in our article on the hidden cost of caregiving.

A Checklist Summary

Step	Action	Time Sensitivity
1	Review determination letter — years covered, expiry, approved categories	Immediate
2	File T1 Adjustment Requests for any retroactive years	High — represents an actual refund once filed
3	Determine optimal claimant for current/future years	Ongoing, revisit if circumstances change
4	Open RDSP if eligible and not already done	High — grant/bond carry-forward diminishes over time
5	Check Canada Caregiver Credit eligibility for supporting family members	Moderate — also has retroactive potential
6	Confirm Child Disability Benefit is being received (if applicable)	Moderate
7	Note renewal date if approval is not permanent	Low until approaching, then high
8	Consider estate planning and caregiver retirement implications	Low urgency, but benefits from early attention

Why This List Matters

Each of these steps is administered by a different system — the CRA for tax adjustments and the DTC itself, financial institutions for RDSPs, the Canada Child Benefit system for the Child Disability Benefit. None of these systems automatically triggers the others. A family that receives DTC approval and stops there — assuming the "hard part" is done — may be accessing only a portion of what the approval actually makes available, sometimes a small portion relative to the total.
