Disability tax credit for mental health conditions in Canada
CRA mental functions criteria, certification and what an approval opens up
Disability tax credit for depression, anxiety and PTSD in Canada: the CRA mental functions criteria, who can certify, and what an approval unlocks.
The Canada Revenue Agency does not approve the disability tax credit because of a diagnosis. It approves it on the effects of an impairment, measured against the mental functions a person needs for everyday life. Depression, anxiety, post-traumatic stress disorder and bipolar disorder can all meet that test. None of them qualifies automatically.
That distinction decides most mental health files. An application that describes a condition tends to be refused. An application that describes concrete daily restriction, certified by a practitioner allowed to certify mental functions, gives a CRA reviewer something to assess against the criteria.
Federal rules and amounts checked against Canada.ca on September 14, 2026. This is general information about the disability tax credit, not tax, legal or medical advice, and nothing here guarantees CRA approval.
Can you get the disability tax credit for depression or anxiety?
Yes, when the effects are severe enough. The CRA grants the credit if an impairment leaves you unable to perform the mental functions necessary for everyday life, or makes them take three times longer than for someone of similar age without the impairment, even with appropriate therapy, medication and devices. The restriction must also be near constant and prolonged.
Nothing in the rules ranks one condition above another. A person living with treatment-resistant depression and a person with a physical impairment face the same four questions: what can you not do, how much longer does it take, how often, and how long has it been that way. The disability tax credit is a non-refundable federal credit, so it reduces income tax payable rather than paying out money on its own.
A diagnosis still matters. It explains the cause of the restriction and supports the expected duration. It is the context of the file, not the argument.
Which mental functions does the CRA assess?
The CRA works from a fixed list of mental function categories. Your practitioner certifies against those categories rather than against a diagnostic label. Applications that translate symptoms into adaptive functioning, attention, concentration, judgment, memory, problem-solving or regulation of behaviour are far easier for a reviewer to weigh.
| Mental function category | What the CRA includes in it |
|---|---|
| Adaptive functioning | Adapting to change, expressing basic needs, going into the community, initiating common simple transactions, basic hygiene and self-care, performing necessary everyday tasks |
| Attention | Showing awareness of danger and risks to personal safety, demonstrating basic impulse control |
| Concentration | Focusing on a simple task for any length of time, understanding and recalling short-term information |
| Goal-setting | Making and carrying out simple plans, initiating everyday tasks |
| Judgment | Choosing clothing appropriate for the weather, deciding about your own treatment and welfare, recognizing the risk of being taken advantage of, understanding consequences |
| Memory | Remembering basic personal information, remembering things that are important and of interest, remembering simple instructions |
| Perception of reality | Showing an accurate understanding of reality, separating reality from delusions and hallucinations |
| Problem-solving | Identifying everyday problems, carrying out solutions to simple problems |
| Regulating behaviour and emotions | Behaving appropriately for the situation, showing appropriate emotional responses, controlling mood to prevent risk of harm to self or others |
| Verbal and non-verbal comprehension | Understanding and responding to verbal information, understanding and responding to non-verbal cues |
A marked restriction in a single category can qualify on its own. Where no single category reaches that level, the CRA can also apply the cumulative effect of significant limitations, which combines two limitations that together equal one marked restriction. The category list and that rule both come from the CRA page on mental functions eligibility.
How severe and how often does the restriction have to be?
Three tests apply at the same time, and all three must be met. Two out of three is a refusal. This is where mental health applications most often fail: the symptoms are real and documented, but the form never establishes the frequency or the time multiplier the CRA is measuring.
| Test | What the CRA requires | Where mental health files break down |
|---|---|---|
| Degree | Unable to perform mental functions necessary for everyday life, or taking three times longer than someone of similar age without the impairment, even with appropriate therapy, medication and devices | The form says a task is difficult or exhausting but never compares it to how long it should take |
| Frequency | Present all or almost all of the time, which the CRA describes as generally 90% or more | Wording built around episodes or bad weeks reads as well under 90% of the time |
| Duration | Has lasted, or is expected to last, for a continuous period of at least 12 months | A recent diagnosis with no treatment history and no stated prognosis |
The phrase "even with appropriate therapy, medication and devices" cuts both ways. Being in treatment does not disqualify anyone. The question is what the restriction looks like while treatment is in place, which is exactly what a practitioner who has followed you for a year can describe.
What this looks like for depression, PTSD, anxiety and bipolar disorder
The CRA never lists qualifying conditions, so the useful exercise is mapping each condition onto the categories above. The descriptions below are examples of how restriction is usually expressed for these conditions. They are not eligibility promises, and only your practitioner can certify what applies to you.
Depression
Major depressive disorder most often touches concentration, memory, goal-setting and adaptive functioning. Concrete detail carries the file: needing prompting to eat or shower, being unable to start or finish routine tasks without another person present, taking most of a day to complete something that used to take an hour. Low mood on its own is not what the CRA measures.
Post-traumatic stress disorder
PTSD files usually rest on regulating behaviour and emotions, attention and adaptive functioning. Relevant detail includes avoidance that prevents leaving home or entering public spaces, hypervigilance that blocks sustained attention, and dissociation or intrusive symptoms that interrupt everyday tasks. Sleep disruption matters mainly through its documented effect on daytime functioning.
Anxiety disorders
Generalized anxiety, panic disorder and severe social anxiety tend to restrict adaptive functioning, concentration and problem-solving. What a reviewer can use: being unable to make phone calls, attend appointments or handle simple transactions without support, and avoidance that is constant rather than triggered by occasional events.
Bipolar disorder
Bipolar disorder raises the frequency test more sharply than the others, because a cycling condition can look intermittent on paper. The file has to show the restriction across the whole cycle rather than during episodes only, covering judgment, regulation of behaviour and emotions, and the periods between episodes.
Who can certify a mental health impairment?
Three practitioners can certify mental functions: a medical doctor, a nurse practitioner and a psychologist. That psychologist option matters, because a psychologist who has treated you for months may document functional restriction in more detail than a family doctor with fifteen-minute appointments.
| Medical practitioner | Impairments they may certify |
|---|---|
| Medical doctor | All impairments |
| Nurse practitioner | All impairments |
| Psychologist | Mental functions |
| Occupational therapist | Walking, feeding, dressing |
| Physiotherapist | Walking |
| Optometrist | Vision |
| Audiologist | Hearing |
| Speech-language pathologist | Speaking |
The applicant fills out Part A of the application, online through a CRA account or by phone, then hands the reference number to the practitioner, who completes Part B. Both parts must travel the same way, digital or paper, and the reference number is valid for up to 12 months and can be used once. An applicant who fills out Part B is not processed. The mechanics are covered in our guide to the T2201 form.
A practitioner may charge for completing the form. You pay it, and you may be able to claim it as a medical expense on line 33099 or 33199 of your return.
What makes a mental health application stronger?
Specificity is what separates an approval from a refusal. The CRA decides on the information the practitioner provides, so the strongest files replace adjectives with observable facts: which tasks need help, how often that help is needed, how much longer each task takes, and what happens when nobody is there.
Bring your practitioner concrete material before the appointment. A short log of the last few months, the tasks someone else takes over for you, the appointments missed, the reminders required, how long ordinary tasks now take against how long they used to. Name the supports already in place, because a restriction that persists despite medication and therapy is exactly what the criteria describe.
If the CRA needs more, it writes to the practitioner, who then has 60 business days to answer. You are told in writing that this request was made. Treat that letter as the decisive moment of the file rather than a formality, because the answer it produces is what the reviewer weighs.
What happens if the CRA denies the application?
The notice of determination states the reason. Compare it line by line against your copy of Form T2201 and the eligibility criteria. Most refusals in mental health files come down to insufficient functional detail rather than a decision that the condition is not serious.
From there you have three routes: request a review and submit new documentation, file an objection, or call the CRA to discuss the decision. New information from your practitioner is usually the fastest of the three. If you remain ineligible, other disability deductions and credits may still apply.
Approval is not always permanent. A notice with no expiry date needs no further application unless the CRA asks. A notice with an expiry date requires reapplying at the end of the period, and the CRA notifies you a year in advance on your notice of assessment. You must also tell the CRA in writing if your condition improves to the point where you no longer meet the criteria.
What DTC approval unlocks beyond the tax credit
For mental health claimants the tax credit is often the smaller half of the outcome. An approved certificate is the entry condition for several federal programs, and some of them pay money rather than reducing tax payable. That is why the application is worth the effort even when your taxable income is low.
| Program | Who it is for | Key figure |
|---|---|---|
| Disability amount on your return | The person with the impairment, with unused amounts transferable to a supporting family member | $10,138 for the 2025 tax year, plus up to $5,914 for a person under 18 at year end |
| Canada disability benefit | Approved DTC holders aged 18 to 64 who meet the residency and tax filing conditions | Maximum $204.20 per month from July 2026 to June 2027, income-tested |
| Registered disability savings plan | Approved DTC holders, as the plan cannot be opened without the credit | Federal grants and bonds paid into the plan |
| Child disability benefit | Families of an approved child under 18 | Paid monthly with the Canada child benefit |
| Canada workers benefit disability supplement | Approved DTC holders with working income | Claimed on the tax return |

The credit itself can also be claimed for past years, going back up to 10 years, which is covered in our guide to the retroactive disability tax credit.

How Quebec treats a mental function impairment
Quebec runs a separate claim. Revenu Quebec offers an amount for a severe and prolonged impairment in mental or physical functions, claimed on line 376 of the provincial return, and it has its own certificate. A federal approval does not apply itself automatically to your Quebec return.
The provincial certificate is form TP-752.0.14-V. Revenu Quebec accepts a copy of the federal Form T2201 instead in most situations, and a psychologist is among the professionals who can certify the impairment. The provincial test also runs on functional restriction rather than diagnosis, so the material you prepare for the federal file is the same material you need here.
Frequently asked questions
Is depression enough on its own to qualify for the disability tax credit?
No. A diagnosis of depression never qualifies by itself. The CRA looks at whether the impairment leaves you unable to perform mental functions necessary for everyday life, or makes them take three times longer, at least 90% of the time, for a period of at least 12 months.
Does taking medication or being in therapy hurt my application?
No. The criteria are assessed with appropriate therapy, medication and devices already in place. The question is what restriction remains while you are being treated. A practitioner describing persistent limitation despite ongoing treatment is answering the criteria correctly, not weakening the file.
Can a psychologist complete the DTC application?
Yes, for mental functions. Medical doctors, nurse practitioners and psychologists are the three practitioners who may certify an impairment in mental functions on the application. A psychologist who has treated you over time often has the detailed functional record the CRA is asking for.
What if my condition comes and goes?
Episodic conditions are harder because of the 90% frequency test, not impossible. The file has to describe restriction that persists between acute episodes rather than only during them. If no single category reaches a marked restriction, the cumulative effect of two significant limitations may still apply.
How far back can I claim if I am approved?
Up to 10 years. If you were eligible in past years but did not claim the disability amount, you can ask the CRA to adjust those returns or adjust them yourself online. Your notice of determination states which years the approval covers, which sets the limit in practice.
Do I need the DTC to get the Canada disability benefit?
Yes. Approval for the disability tax credit is a requirement for the Canada disability benefit, along with being 18 to 64, meeting the residency conditions and having filed the required tax return. The maximum is $204.20 per month for July 2026 to June 2027, reduced by family income.
Where to start
Book time with the practitioner who knows your functional history best, bring written examples of daily restriction rather than a symptom list, and confirm they can certify mental functions before the appointment. If approval is the goal because you want to open a savings plan, you can check where you stand first and work back from there.
