Formula & methodology

Formula used

federal DTC amount = $10,341 base + $6,032 (if under 18)
tax reduction = DTC amount × applicable marginal rate (federal + provincial)

The DTC is a non-refundable credit, not a deduction: it's a fixed dollar amount multiplied by the lowest marginal tax rate, then subtracted directly from tax owed — not from taxable income.

Step-by-step calculation

1. DTC amount
$10,341 for 2026, plus a $6,032 supplement if the person is under 18 at year end (CRA line 31600).
2. Federal tax reduction
DTC amount × 14% (the lowest federal bracket rate).
3. Provincial tax reduction
DTC amount × your province's lowest marginal rate.
4. Retroactive refund
Annual tax reduction × the number of prior years you're claiming, assuming similar income across those years (a simplification — actual retroactive value depends on each year's rates and income).
5. Caregiver transfer
If unused, the credit's value to a supporting family member is estimated at the DTC amount × their approximate marginal rate.

Limitations

Retroactive refund assumes similar income and rates in prior years — CRA recalculates each year individually using that year's actual rates.
Caregiver marginal rate is approximated from income bands, not a full tax calculation.
Does not model the reduction to the under-18 supplement once child care or attendant care costs exceed the CRA threshold.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What is the Disability Tax Credit (DTC) and who is eligible?

Tap to view the answer

The DTC is a non-refundable tax credit for Canadians with a prolonged physical or mental impairment. Eligibility is determined by the CRA using Form T2201, signed by a medical practitioner. The 2026 federal amount is $10,341 (plus a $6,032 supplement for someone under 18). It reduces your tax payable and may unlock other benefits like the RDSP.

Can I claim the DTC retroactively?

Tap to view the answer

Yes. If your disability started in a prior year, you can request an adjustment for up to 10 years back. The calculator estimates retroactive refunds based on the number of eligible years you enter, assuming similar income and rates across those years.

What happens if I can't use the entire DTC?

Tap to view the answer

Unused portions of the DTC can often be transferred to a supporting family member (spouse, parent, child, etc.). This calculator shows the estimated value of a caregiver transfer if you choose that option.

How does DTC approval affect my RDSP?

Tap to view the answer

DTC eligibility is a requirement to open a Registered Disability Savings Plan (RDSP). Once approved, you may receive Canada Disability Savings Grants and Bonds. The calculator highlights this RDSP linkage.

Does this calculator cover all provinces?

Tap to view the answer

Yes, it works for all provinces and territories. Provincial DTC amounts vary, and the calculator uses your selected province to estimate the combined federal-provincial tax reduction.

Understanding the Disability Tax Credit

What the DTC is, and why it opens other doors

The Disability Tax Credit is a non-refundable tax credit for people with a severe and prolonged impairment in physical or mental functions. For 2026 the federal base amount is $10,341, with a supplement of $6,032 for those under 18.

Being non-refundable means it reduces tax owing but cannot create a refund on its own — someone with no tax payable gets nothing directly. Its real significance is as a gateway. DTC approval is the eligibility requirement for the Registered Disability Savings Plan, the Child Disability Benefit, the disability supplement to the Canada Workers Benefit, and the Home Accessibility Tax Credit. Many families find the RDSP grants worth far more than the credit itself.

Qualifying is about function, not diagnosis

The Canada Revenue Agency does not maintain a list of qualifying conditions. Approval turns on how an impairment affects daily functioning, which is why two people with the same diagnosis can receive different decisions.

You must be markedly restricted in at least one basic activity of daily living — walking, speaking, hearing, feeding, dressing, eliminating, or mental functions necessary for everyday life — or significantly restricted in two or more in a cumulative way, or require life-sustaining therapy at least three times a week. "Markedly restricted" means all or substantially all of the time, even with appropriate therapy and devices. The restriction must have lasted, or be expected to last, at least twelve continuous months.

Applying, and why applications get refused

Form T2201 has two parts: your section, and a certification from a medical practitioner. A doctor, nurse practitioner, optometrist, audiologist, occupational therapist, physiotherapist, psychologist or speech-language pathologist can certify, depending on the impairment.

Most refusals come down to vague wording rather than an ineligible condition. A practitioner who writes that a patient "has difficulty walking" has not established a marked restriction; one who writes that they take three times as long as an average person to walk 100 metres, on all or substantially all days, even with a mobility aid, has. Bring specific examples to the appointment. If refused, you can request a review or file a formal objection within 90 days, often succeeding with better documentation.

Transferring the credit and claiming retroactively

If you cannot use the full credit because your tax owing is too low, the unused portion can be transferred to a supporting spouse, common-law partner, parent, grandparent, child, sibling, aunt, uncle, niece or nephew who supported you.

Approval can also be backdated up to ten years if the impairment existed then. This is where the DTC becomes financially significant: a successful retroactive claim covering several years, adjusted across a family's returns, can produce a refund in the tens of thousands. Request the adjustment through the T1 Adjustment process or by asking the CRA to reassess the affected years. Be wary of firms charging a large percentage of the refund to do paperwork you can file yourself for free.

The RDSP and the grants that follow approval

A Registered Disability Savings Plan is available once the DTC is approved, and the government contributions are unusually generous. The Canada Disability Savings Grant matches contributions at up to 300% for lower-income beneficiaries: a $1,500 contribution can attract $3,500 in grant.

The grant pays 300% on the first $500 and 200% on the next $1,000 where family income is below the threshold, and 100% on the first $1,000 above it. Lifetime grant is capped at $70,000. Lower-income beneficiaries may also receive the Canada Disability Savings Bond of up to $1,000 a year with no contribution at all, to a $20,000 lifetime maximum. There is a ten-year holdback rule, so withdrawals made too soon can require repaying recent grants.

Other supports that open up

DTC approval also unlocks the Child Disability Benefit, a tax-free monthly amount of up to $3,480 a year per eligible child, paid automatically with the Canada Child Benefit once approved.

Provincial amounts stack on top of the federal credit and vary considerably — Alberta's provincial disability amount is substantially larger than Ontario's. Approval can also support claims for attendant care as a medical expense, the Home Accessibility Tax Credit for renovations improving access, and the disability supplement to the Canada Workers Benefit. Because these follow automatically from approval, the single most valuable step is getting the T2201 certified properly the first time.

Formula & methodology

Formula used

federal DTC amount = $10,341 base + $6,032 (if under 18)
tax reduction = DTC amount × applicable marginal rate (federal + provincial)

The DTC is a non-refundable credit, not a deduction: it's a fixed dollar amount multiplied by the lowest marginal tax rate, then subtracted directly from tax owed — not from taxable income.

Step-by-step calculation

1. DTC amount
$10,341 for 2026, plus a $6,032 supplement if the person is under 18 at year end (CRA line 31600).
2. Federal tax reduction
DTC amount × 14% (the lowest federal bracket rate).
3. Provincial tax reduction
DTC amount × your province's lowest marginal rate.
4. Retroactive refund
Annual tax reduction × the number of prior years you're claiming, assuming similar income across those years (a simplification — actual retroactive value depends on each year's rates and income).
5. Caregiver transfer
If unused, the credit's value to a supporting family member is estimated at the DTC amount × their approximate marginal rate.

Limitations

Retroactive refund assumes similar income and rates in prior years — CRA recalculates each year individually using that year's actual rates.
Caregiver marginal rate is approximated from income bands, not a full tax calculation.
Does not model the reduction to the under-18 supplement once child care or attendant care costs exceed the CRA threshold.
