Child Disability Benefit 2026: $290/Month + DTC Guide

Quick Answers - Child Disability Benefit 2026:

• How much? Up to $290.00 per month, or $3,480 a year, per eligible child for July 2026 to June 2027, based on your 2025 adjusted family net income ^[1]
• Do I apply? No separate application. CRA adds it to your Canada Child Benefit automatically once your child is approved for the disability tax credit ^[1]
• Two gates: You must qualify for the Canada Child Benefit, and your child must be DTC approved. Both have to stay open ^[1][2]
• Where it stops: Reduction starts above $82,847 and reaches zero at $191,597 with one eligible child ^[1]
• Newcomers: The status test applies to you or your spouse, not separately to your child. Temporary residents need the 18-month rule ^[2]
• Not the same as the Canada Disability Benefit. That one is for adults 18 to 64 and needs its own Service Canada application ^[32][34]
• Back pay: CRA automatically works out only the current and two previous benefit years. Older months need a letter ^[1]

The Child Disability Benefit is a tax-free monthly supplement for families raising a child under 18 with a severe and prolonged impairment ^[1]. For July 2026 to June 2027, the maximum is $290.00 per month, or $3,480 a year, for each eligible child ^[1].

You do not apply for it. That is the single most useful thing to know about this program, and also the most misleading. There is no Child Disability Benefit application form, because CRA calculates it automatically and folds it into your Canada Child Benefit payment ^[1]. What you actually have to win is the disability tax credit for your child, and that is a medical certification process that turns down a lot of families who assumed a diagnosis would be enough ^[7].

This guide covers both halves: getting your child approved, and everything that approval is worth. The monthly payment is genuinely the smaller part.

Is this the same as the Canada Disability Benefit?

No, and this is worth settling before anything else. Two different federal programs share the letters "CDB." They have different administrators, different ages, different amounts and different application rules.

	Child Disability Benefit	Canada Disability Benefit
Who runs it	Canada Revenue Agency [1]	Service Canada [32]
Who it is for	Family of a DTC-approved child under 18 [1]	DTC-approved adult, 18 to 64 [32]
How it is paid	Supplement inside your Canada Child Benefit [1]	Separate monthly payment [33]
Maximum, July 2026 to June 2027	$290.00 per month per child [1]	$204.20 per month [33]
Application	None. Automatic once both gates are met [1]	Required, through Service Canada [34]
Income used for 2026 to 2027	2025 adjusted family net income [1]	2025 adjusted family net income [33]
Taxable	No [1]	No [32]

The overlap is real, not just naming. Both programs run through the same disability tax credit approval, and a child who is DTC approved keeps that approval past their 18th birthday. What does not carry over is the money. The Child Disability Benefit ends after the birthday month, and the adult benefit has to be applied for separately ^[1][34]. Our Canada Disability Benefit guide covers the adult program in full, and the age-18 section further down explains how to bridge the two without a gap.

What is the Child Disability Benefit?

It is a monthly, tax-free, income-tested payment made to the person who already receives the Canada Child Benefit for a child under 18 who qualifies for the disability tax credit ^[1]. Related guide: Low-Income Extended Health Benefits Canada 2026: Start Here

Key facts:

• Paid with the Canada Child Benefit, on the same date, in the same deposit ^[3]
• No separate application once you meet both eligibility gates ^[1]
• Tax-free, not reported as income, and no tax slip is issued ^[1][2]
• Income-tested on your adjusted family net income from your tax return ^[1]
• Per child, so two eligible children means two maximums ^[1]
• Indexed annually under the Income Tax Act, using the change in the Consumer Price Index ^[6]

The amount rose from $284.25 a month in the July 2025 to June 2026 year to $290.00 for July 2026 to June 2027, an increase of $5.75 a month or $69 a year ^[1][36].

Because it lives inside the Canada Child Benefit, everything that governs the CCB governs this too: the July-to-June benefit year, the tax return that feeds it, the payment dates and the shared-custody rules. Our Canada Child Benefit guide covers the main benefit; this guide covers the disability supplement.

Who qualifies for the Child Disability Benefit?

There are exactly two gates, and both have to be open at the same time ^[1].

Gate 1: you qualify for the Canada Child Benefit

You must be legally eligible for the Canada Child Benefit for that child, which generally means you ^[2]:

• are a resident of Canada for income tax purposes
• live with the child, who is under 18
• are primarily responsible for the child's care and upbringing
• meet the status condition through yourself or your spouse or common-law partner

There is an important distinction here that trips up higher-income families. Being eligible for the program is not the same as receiving a positive regular Canada Child Benefit amount. The ordinary CCB can be reduced to zero by income while you remain eligible for the program, and the disability supplement is calculated separately with its own phase-out ^[1][6]. So apply even if you think you earn too much for the CCB.

Gate 2: your child is approved for the disability tax credit

CRA must have approved your child for the DTC, normally after reviewing Form T2201, Disability Tax Credit Certificate ^[12][13].

This is the gate that actually decides most cases, and it is not a formality. The DTC is granted on the effects of an impairment, not on the diagnosis ^[7][8]. That distinction is the subject of the next section.

If either gate closes

• CCB eligibility ends - the Child Disability Benefit ends with it ^[1]
• DTC approval expires or is lost - the disability supplement stops, though the ordinary CCB can continue ^[1][25]
• Both stay valid - CRA keeps calculating the supplement each July ^[1]

Both you and your spouse or common-law partner have to file a tax return every year, even with no income at all, because CRA needs both returns to work out your adjusted family net income ^[1][2]. A missing return is one of the most common reasons payments simply stop.

How does your child get approved for the DTC?

The disability tax credit asks a specific question: compared with a child of similar age without the impairment, what can your child not do?

The general test

For most categories, your child is markedly restricted when, even with appropriate therapy, medication and devices, your child ^[7][8]:

• cannot perform the activity, or takes at least three times longer than a child of similar age without the impairment; and
• the restriction exists all or substantially all of the time, generally at least 90 percent of the time; and
• it has lasted, or is expected to last, at least 12 continuous months

The age comparison matters enormously for children. A four-year-old who needs help dressing is a four-year-old. The application has to show restriction beyond what is normal for that age ^[7][8].

The categories

Category	What it covers
Walking	Ability to walk, with aids and therapy in place [7]
Speaking	Being understood by a familiar listener in a quiet setting [7]
Hearing	Understanding a familiar person in a quiet setting [7]
Vision	Acuity and field of vision after correction [7]
Feeding and dressing	Preparing and eating food; dressing oneself [7]
Eliminating	Bowel and bladder functions [7]
Mental functions	Attention, memory, judgement, problem solving, goal setting, regulation of behaviour and emotion, adaptive functioning [9]
Life-sustaining therapy	Therapy needed to support a vital function, at the required frequency [11]
Cumulative effect	Significant restriction in two or more categories that together equal a marked restriction [10]

Two of these deserve emphasis for children:

Mental functions is where most childhood applications live: autism, ADHD, learning disabilities, intellectual disability, acquired brain injury, severe anxiety. CRA publishes examples specifically for this category, and it assesses the functional effects, not the label ^[9].

Cumulative effect is the most under-used route. A child who is significantly restricted in several areas, none of them severe enough on its own, can still qualify when the restrictions are added together ^[10]. If a straightforward single-category application was denied, this is often the section that was left empty.

The one diagnosis-based rule

Type 1 diabetes is the exception. For 2021 and later tax years, a person with type 1 diabetes is deemed to meet the life-sustaining therapy requirement of 14 hours per week ^[11]. Every other condition is judged on effects.

Everything else, including conditions that sound obviously disabling, still needs the functional evidence. Do not assume a well-known diagnosis makes the T2201 a formality.

Filling in the T2201

Part A is yours. It identifies the child, and it asks whether CRA should automatically adjust your previous tax returns. Say yes ^[12][15]. It also asks who the supporting family member is, which matters later for the transfer of the credit.

Part B is completed by an authorized medical practitioner: a medical doctor or nurse practitioner for any category, and a specialist for certain ones, such as an optometrist for vision or a psychologist for mental functions ^[12].

You can complete the form through CRA's digital application or on paper ^[12]. Practitioners may charge for completing the form; that fee is a medical expense you can claim ^[26].

The single most consequential field is the date the practitioner gives for when the effects began. That date sets how far back both your tax refunds and your benefit back payments can reach ^[14]. If your child's records show the restrictions started earlier than the date on the form, raise it with the practitioner before it is submitted.

If CRA says no

The notice of determination explains the decision and lists the approved years ^[14]. If you disagree:

1. Ask for a review. Send new or expanded medical information, or a letter from a practitioner who knows your child ^[14].
2. Protect the deadline. You have 90 days from the notice of determination to file a formal objection ^[14]. An informal review request does not stop that clock. If the 90 days are running out while you gather documents, file the objection anyway.
3. Check what was actually assessed. Denials often turn on a single unanswered question about frequency or duration, or on a cumulative-effect section that was never completed ^[10].

How much can you actually get?

The maximum

Benefit year	Per month, per eligible child	Per year	Reduction starts above
July 2025 to June 2026	$284.25	$3,411	$81,222 [36]
July 2026 to June 2027	$290.00	$3,480	$82,847 [1]

The amount is per eligible child. Two DTC-approved children means a family maximum of $6,960 a year ^[1].

How income reduces it

Above $82,847 of adjusted family net income, the annual amount comes down ^[1]:

• One eligible child: 3.2 percent of the income above $82,847
• Two or more eligible children: 5.7 percent of the income above $82,847

The 5.7 percent is one family-level reduction, not 5.7 percent applied separately to each child's amount ^[6]. That detail is why a second eligible child is worth so much: the maximum doubles while the reduction rate rises by only 2.5 points.

One child, $100,000 income:

$100,000 - $82,847      = $17,153 above the threshold
$17,153 x 3.2%          = $548.90 annual reduction
$3,480 - $548.90        = $2,931.10 a year
                        = about $244 a month

Two children, $100,000 income:

$3,480 x 2              = $6,960 family maximum
$100,000 - $82,847      = $17,153 above the threshold
$17,153 x 5.7%          = $977.72 annual reduction
$6,960 - $977.72        = $5,982.28 a year
                        = about $499 a month

Where it runs out

Eligible children	Benefit reaches zero at
One	$191,597 [1]
Exactly two	about $204,952 [1]
Three or more	Higher again, since each child adds $3,480 to the starting maximum [1][6]

Actual payments are subject to CRA's own calculation and rounding ^[1]. Use CRA's child and family benefits calculator for your own figures rather than relying on arithmetic here.

Adjusted family net income

AFNI starts from the combined line 23600 net income of you and your spouse or common-law partner, subtracts any Universal Child Care Benefit and registered disability savings plan income, and adds back repayments of those amounts ^[3].

Note what is not in there: the Canada Child Benefit and the Child Disability Benefit themselves are not taxable income, so receiving them never reduces next year's payment ^[1][2].

When do payments arrive?

The Child Disability Benefit is not a separate deposit. CRA adds it to your Canada Child Benefit and pays the combined amount on the CCB schedule ^[3].

CRA has published these dates for the 2026 half of the benefit year ^[4]:

Benefit month	Payment date
July 2026	July 20, 2026
August 2026	August 20, 2026
September 2026	September 18, 2026
October 2026	October 20, 2026
November 2026	November 20, 2026
December 2026	December 11, 2026

Payments generally land on the 20th of the month, moving to the preceding business day when the 20th falls on a weekend or federal statutory holiday ^[2]. CRA had not published the January to June 2027 dates when this guide was written, so treat the monthly pattern as a guide and confirm the exact dates on CRA's payment dates page ^[4].

Each July, CRA recalculates using the previous calendar year's returns. July 2026 to June 2027 payments run on your 2025 returns ^[1].

What if your child lives in two homes?

CRA treats an arrangement as shared custody when the child lives with each caregiver between 40 and 60 percent of the time ^[2].

In that case, each parent receives 50 percent of what that parent would have received if the child lived with them full time, calculated using that parent's own adjusted family net income and family situation ^[2][3].

Two things follow from this that surprise people:

• CRA does not calculate one family amount and split it according to your private agreement ^[3].
• The percentage is 50 percent flat. There is no 60/40 split of the money to match a 60/40 split of the time ^[3].

Tell CRA promptly when custody arrangements change. Overpayments get recovered.

Can newcomers get the Child Disability Benefit?

Yes, but the test lives entirely in the Canada Child Benefit rules, not in the disability rules ^[1][2].

The status condition

You or your spouse or common-law partner must be one of the following ^[2]:

• a Canadian citizen
• a permanent resident
• a protected person with a positive decision
• a temporary resident who meets the 18-month rule below
• registered or entitled to be registered under the Indian Act

A pending refugee claim is not the same as protected person status ^[2].

The 18-month rule for temporary residents

A temporary resident must ^[2]:

1. have lived in Canada continuously throughout the previous 18 months, and
2. hold a valid permit in the 19th month that does not say it confers no status or no temporary resident status

The 18 months are a single continuous stretch immediately before the 19th month. Separate earlier stays cannot be added together to reach 18 ^[2]. This is the same structure as the adult Canada Disability Benefit's residency rule, explained in more depth in our Canada Disability Benefit guide.

Your child's own status

The status condition applies to you or your spouse or common-law partner, not separately to the child ^[2]. Your child does not need to be a citizen or permanent resident to satisfy that particular test. Your child does still have to live with you and be under 18, and CRA may ask for proof of birth or immigration documents for a child born outside Canada ^[2].

You can start the DTC first

The disability tax credit has no residence-length or immigration-status waiting period of its own ^[12]. It assesses the impairment and the practitioner's certification.

That means a newcomer family can begin the T2201 immediately, while the 18-month clock is still running, so that DTC approval is already in place when Canada Child Benefit eligibility begins. DTC approval on its own does not create Child Disability Benefit entitlement, but it removes the slower of the two steps from the critical path ^[1][12].

Documents

Applying for the Canada Child Benefit by mail generally uses Form RC66, plus Form RC66SCH for status and income information ^[2]. Proof of birth is required if CRA has not paid benefits for that child before, and documents that are not in English or French need an acceptable translation ^[2].

Foreign medical records

A diagnosis made abroad does not automatically produce DTC approval. The application still has to describe functional effects on CRA's terms ^[7][12]. Bring translated foreign records to the Canadian practitioner who completes Part B; a practitioner may rely on symptoms, medical history, direct observation and knowledge of the impairment ^[12].

How far back can you claim?

This is where the largest amounts of money sit, and where families lose the most by waiting. A backdated DTC approval produces two separate payments through two unrelated processes. They are not one refund.

Pot 1: tax reassessments

The DTC is a non-refundable tax credit. A child with little or no tax payable can transfer the unused amount to a supporting parent, generally claimed on line 31800 ^[15][16].

• You can adjust up to 10 previous tax years ^[15]
• Each year has its own deadline: no refund where the request comes more than 10 calendar years after the end of that tax year ^[17]
• Use Change my return in CRA My Account, ReFILE, or mail Form T1-ADJ ^[17]
• CRA's indicative timing is about two weeks online and 12 weeks by mail, and as long as 36 weeks for multiple years or years outside the normal reassessment period ^[17]

During 2026, the open years are 2016 through 2025. The 2016 year closes on December 31, 2026, whether or not CRA has finished processing your T2201 ^[17]. Waiting for the approval letter does not preserve it.

Pot 2: retroactive Child Disability Benefit

This runs through the child-benefit system instead, and changing your tax returns does not request it ^[17].

• For a first award, CRA automatically calculates the current benefit year and the two previous ones ^[1]
• For earlier benefit years, you must send a written request to your tax centre ^[1]
• The child-benefit limit is a rolling month-by-month one under the Income Tax Act, extending up to 10 years after the beginning of the month concerned, and the extension is discretionary ^[18]

The two limits do not expire the same way

This is the practical point. The tax-year limit closes in a block every December 31. The benefit limit closes one month at a time. In August 2026, the August 2016 benefit month is already gone while the 2016 tax year still has until December 31 ^[17][18]. If your child's approval reaches back several years, send the written benefit request first, because those months are dropping off continuously.

What this can be worth

For a child approved in 2026 with eligibility backdated to January 2023, where a parent can use the full transferred credit and the family qualified for the maximum:

Source	Approximate amount
Federal tax reassessments, 2023 to 2025	about $6,911
Retroactive Child Disability Benefit, January 2023 to June 2026	about $11,399
Combined	about $18,310

This is an illustration built from CRA's published historical amounts, not an estimate of your case ^{[15][36][40][41][42]}. Your reassessments will be lower if the parent had insufficient tax payable, and your benefit will be lower if income reduced it. Provincial disability credits may add more.

Do not let anyone describe a combined figure like this as a single "DTC refund." It is two processes with two deadlines, and one of them requires a letter you have to write yourself.

What else does DTC approval unlock?

The monthly payment is genuinely the smaller half. Approval is a key that opens several other doors, and the largest one has nothing to do with income support.

The registered disability savings plan

An RDSP is a long-term savings plan for a DTC-approved beneficiary, and it is the reason to pursue the DTC even for families who will never see a dollar of the monthly benefit because of income ^[21].

	Lifetime maximum
Canada Disability Savings Grant	$70,000 [22]
Canada Disability Savings Bond	$20,000 [22]
Personal contributions	$200,000 [23]

Two features matter most:

The bond needs no contribution at all. A family with low income can receive the Canada Disability Savings Bond without putting in any money of their own ^[22]. A family that cannot afford to save still qualifies.

Grants and bonds carry forward 10 years. Entitlement accumulates from the year of DTC eligibility, and opening a plan late means those carry-forward years start expiring ^[22]. This is the quiet cost of delay.

Grants are matched at up to 300 percent and 200 percent on the first contribution dollars, depending on family income; for amounts paid in 2026, the enhanced matching applies up to family income of $117,045, the full bond is paid up to family income of $38,237, and bond eligibility ends at family income of $58,523 ^[22].

Before withdrawing, understand the assistance holdback: a withdrawal can require repaying $3 of grant and bond for every $1 withdrawn, up to the holdback amount, for assistance paid in the previous 10 years ^[24]. An RDSP is not an emergency fund.

While your child is a minor, grant and bond calculations use the family income associated with your Canada Child Benefit. From the year your child turns 19, they use your child's own income, which is why your child should start filing a return in the year they turn 17 ^[37].

Tax credits and deductions

Measure	What approval changes
Medical expenses	The credit uses the lesser of 3 percent of net income or a fixed threshold; DTC approval does not make every expense eligible, but it opens categories such as attendant care [26]
Child care expenses	The annual limit for a DTC-eligible child is $11,000 for 2025, above the ordinary age-based limits [27]
Canada caregiver credit	Available for a dependant with a physical or mental impairment [38]
Home accessibility expenses	Renovation costs to make a home safer or more accessible for a qualifying individual [39]

Provincial programs are separate

Federal DTC approval does not enrol your child in any provincial program. Each province runs its own assessment ^{[28][29][30][31]}.

Province	Program	Notes
Ontario	Assistance for Children with Severe Disabilities	$25 to $678 a month; household income generally $77,640 or less; own severity and extraordinary-cost tests [28]
British Columbia	Children and Youth Disability Benefit	Needs-based rather than income-tested; $6,500 a year, or up to $17,000 for higher needs [29]
Alberta	Family Support for Children with Disabilities	No flat monthly amount; individually assessed costs, respite and services [30]
Quebec	Supplement for Handicapped Children	$241 a month in 2026, non-taxable and not income-tested; a separate Retraite Quebec regime, not the federal benefit under another name [31]

British Columbia has also announced a Disability Supplement that will require federal DTC approval, planned at up to $6,000 a year with first payments in July 2027 based on the 2026 tax return ^[29].

Apply to your province separately, and expect a separate medical assessment.

What happens when your child turns 18?

This is the transition that costs families the most, because nothing about it happens automatically.

The cliff

• The Child Disability Benefit's last payment is for the month your child turns 18 ^[1][5]
• The Canada Disability Benefit for adults is a separate program with a separate Service Canada application, and it does not start on its own ^[32][34]

Your child's DTC approval survives the birthday. The money does not.

The adult requirements

To receive the Canada Disability Benefit, your child must ^[32][35]:

• be 18 to 64
• be DTC approved
• be a resident of Canada for income tax purposes
• hold an eligible status
• have filed the required federal return, with a spouse or partner filing where applicable

The maximum is $204.20 a month for July 2026 to June 2027 ^[33].

Apply early, but know what early cannot buy you

Service Canada accepts an application up to six months before the 18th birthday, but cannot decide it until your child actually turns 18 ^[32][34]. Where approval is effective in the birthday month, the regulations make the following month the first payable one ^[35].

Transition timeline

When	What to do
12 to 9 months before 18	Check the DTC expiry date and start recertification if one applies [14]
The year your child turns 17	Have your child file a return, even with zero income, for later RDSP calculations [37]
9 to 6 months before 18	Research provincial adult disability assistance, which has its own tests
6 months before 18	Apply for the Canada Disability Benefit as soon as Service Canada allows [34]
3 to 1 months before 18	Confirm SIN, status documents, address, direct deposit and assessed return
The birthday month	Expect the final Child Disability Benefit payment [1][5]
The following month	Possible first Canada Disability Benefit month, if approved [35]
1 to 3 months after	Follow up on both federal and provincial applications

Do not assume eligibility carries across. The adult program tests your child's own residence, status, returns and DTC approval, not yours ^[32]. A temporary-resident family that qualified through a parent's status has to look at this again from scratch.

What mistakes and scams should you watch for?

Assuming a diagnosis is enough. Apart from type 1 diabetes, the DTC is decided on functional effects with age-appropriate comparison ^[7][11].

Describing only the worst day. The test asks about restriction all or substantially all of the time. Evidence should cover home, school and community, not only crises ^[9][10].

Leaving the cumulative-effect section blank. Significant restrictions in two or more categories can add up to a marked restriction ^[10]. Many denied applications never made this argument.

Not checking the practitioner's dates. An unnecessarily late start date silently shortens both your refund years and your back payments ^[14].

Missing the 90-day objection deadline. An informal review request does not pause it ^[14].

Waiting for automatic back payments. CRA works out only the current and two previous benefit years by itself. Older months need a letter, and they expire monthly ^[1][18].

Letting DTC approval expire. An expiry gap stops the benefit and stops new RDSP grants and bonds ^[14][25]. Reapply during the expiry year.

Not opening an RDSP because you cannot afford to contribute. The bond requires no contribution, and carry-forward years expire ^[22].

Assuming provincial enrolment is automatic. It is not, anywhere ^{[28][29][30][31]}.

Paying a promoter a large percentage of your refund. The federal fee cap in the Disability Tax Credit Promoters Restrictions Regulations is currently suspended by a court injunction, so do not assume a legal limit is protecting you ^[19][20]. No promoter can guarantee approval, the medical section still has to be completed by your child's own practitioner, and you can submit the T2201 yourself at no cost ^[12].

Key Takeaways

• The Child Disability Benefit pays up to $290.00 a month per eligible child for July 2026 to June 2027, tax-free, on top of your Canada Child Benefit ^[1]
• There is no application. CRA adds it automatically once you qualify for the CCB and your child is DTC approved ^[1]
• The disability tax credit is the real gate, and it is decided on functional effects, not on a diagnosis ^[7]
• Reduction starts at $82,847 and the benefit reaches zero at $191,597 with one eligible child ^[1]
• Newcomers qualify through the CCB status rules; the test applies to you or your spouse, not separately to your child, and temporary residents need 18 continuous months ^[2]
• You can start the T2201 before your family becomes CCB-eligible, because the DTC has no waiting period of its own ^[12]
• Back pay comes in two separate pots with two different deadlines: tax years close every December 31, benefit months close one at a time ^[17][18]
• Approval also unlocks an RDSP worth up to $90,000 in grants and bonds, and the bond needs no contribution ^[22]
• The benefit ends with the birthday month at 18, and the adult Canada Disability Benefit must be applied for separately ^[1][34]
• Provincial programs are separate applications with their own tests, everywhere in Canada ^{[28][29][30][31]}

This guide is general information, not tax, medical or financial advice. Amounts and rules change every July, so confirm your situation with CRA.

FAQ

Q: How much is the Child Disability Benefit in 2026?

A: The maximum is $290.00 per month, or $3,480 per year, for each eligible child, for the July 2026 to June 2027 benefit year. Your actual amount depends on your 2025 adjusted family net income. The previous benefit year paid a maximum of $284.25 per month ^[1][36].

Q: Is the Child Disability Benefit the same as the Canada Disability Benefit?

A: No. They are two different federal programs that share the letters CDB. The Child Disability Benefit is a CRA supplement paid inside your Canada Child Benefit for a DTC-approved child under 18. The Canada Disability Benefit is a separate Service Canada payment for DTC-approved adults aged 18 to 64, and it needs its own application ^[1][32].

Q: Do I have to apply for the Child Disability Benefit?

A: No. There is no separate application. Once you are eligible for the Canada Child Benefit and CRA has approved your child for the disability tax credit, CRA calculates it automatically and adds it to your monthly payment ^[1].

Q: Does an autism or ADHD diagnosis automatically qualify my child?

A: No. Apart from a specific rule for type 1 diabetes, the disability tax credit is decided on the effects of the impairment, not the diagnosis. The T2201 has to show that your child is markedly restricted, or significantly restricted in two or more categories, compared with a child of similar age without the impairment ^{[7][9][10][11]}.

Q: At what income does the Child Disability Benefit stop?

A: For July 2026 to June 2027 the reduction starts once adjusted family net income passes $82,847. With one eligible child the benefit reaches zero at $191,597. With exactly two eligible children it runs out at about $204,952, because the maximum doubles while the reduction rate rises only to 5.7 percent ^[1].

Q: Can newcomers get the Child Disability Benefit?

A: Yes, if you qualify for the Canada Child Benefit. You must be a Canadian resident for tax purposes, and you or your spouse or common-law partner must be a citizen, permanent resident, protected person, a temporary resident who meets the 18-month rule, or registered or entitled to be registered under the Indian Act ^[2].

Q: Does my child need to be a permanent resident or citizen?

A: The status condition applies to you or your spouse or common-law partner, not separately to the child. Your child still has to live with you and be under 18. CRA may ask for proof of birth or immigration documents for a child born outside Canada ^[2].

Q: Can I apply for the DTC before we qualify for the Canada Child Benefit?

A: Yes. The disability tax credit has no residence-length or immigration-status waiting period of its own, so you can start the T2201 as soon as a Canadian-authorized practitioner can complete it. But DTC approval alone does not create Child Disability Benefit entitlement until you also meet the Canada Child Benefit rules ^[1][12].

Q: How far back can we claim?

A: Two separate limits apply. A parent can adjust up to 10 previous tax years for the disability amount, and each tax year closes on December 31 of its own tenth year. For the benefit itself, CRA automatically calculates only the current and two previous benefit years, and older months need a written request to your tax centre under a different month-by-month rule ^{[1][15][17][18]}.

Q: Is a retroactive Child Disability Benefit payment taxable?

A: No. The Child Disability Benefit is tax-free, whether it arrives monthly or as a lump sum, and it is not reported as income on your return. Provincial assistance and housing programs can use their own income and asset definitions, so check with those programs before spending a large back payment ^[1][2].

Q: What else does DTC approval unlock?

A: A registered disability savings plan with up to $70,000 in lifetime grants and $20,000 in lifetime bonds, a higher child care expense limit, medical expense claims, the Canada caregiver credit, home accessibility expenses, and access to several provincial programs that have their own applications ^{[22][26][27][38][39]}.

Q: What happens when my child turns 18?

A: The Child Disability Benefit normally ends with the payment for the month your child turns 18. The adult Canada Disability Benefit does not start automatically. Service Canada accepts an application up to six months before the 18th birthday but cannot decide it until the person actually turns 18 ^[1][5][34].

Q: Do both parents get the benefit in shared custody?

A: If your child lives with each parent between 40 and 60 percent of the time and both parents qualify, each receives 50 percent of what that parent would have received with full-time care. CRA calculates each parent's share using that parent's own adjusted family net income ^[2][3].

Q: Do we both have to file tax returns even with no income?

A: Yes. CRA recalculates your payments every July using both spouses' or common-law partners' returns from the previous calendar year. A missing return stops the payments even when the person had no income at all ^[1][2].

Q: Should we hire a DTC clinic that takes a percentage of the refund?

A: Be careful. The federal fee cap for DTC promoters is currently suspended by a court injunction, so do not assume a legal limit protects you. No promoter can guarantee approval, the T2201 medical section has to be completed by your child's practitioner, and you can file it yourself for free ^[12][19][20].
