Sleep apnea may qualify for the Disability Tax Credit when it causes severe and prolonged limitations in everyday functioning that meet the Canada Revenue Agency’s requirements.
A sleep apnea diagnosis, severe sleep-study result or CPAP prescription does not automatically qualify someone for the Disability Tax Credit, commonly called the DTC.
The CRA considers the effects of the condition rather than the diagnosis alone. Eligibility may involve a marked restriction in an eligible everyday activity, the cumulative effect of significant limitations in multiple categories or qualifying life-sustaining therapy.
The DTC is different from short-term disability, long-term disability and CPP Disability. Those benefits generally focus on the ability to work, while the DTC focuses on severe limitations in everyday functioning.

Does Sleep Apnea Qualify for the Disability Tax Credit in Canada?
Sleep apnea may qualify for the DTC, but approval is based on severe and prolonged functional limitations—not the condition itself.
The CRA may approve a person who:
-
Has a marked restriction in one eligible category
-
Has significant limitations in two or more categories whose cumulative effect is equivalent to one marked restriction
-
Receives qualifying life-sustaining therapy
For most eligible categories, a marked restriction generally means that the person:
-
Is unable to perform the activity or takes approximately three times longer than a similar-aged person without the impairment
-
Experiences the restriction all or almost all of the time, generally at least 90 per cent
-
Has had, or is expected to have, the impairment for at least 12 continuous months
Does Severe Sleep Apnea Automatically Qualify?
No. Mild, moderate or severe sleep apnea classifications are based on medical testing, but they do not determine DTC eligibility.
A person with severe obstructive sleep apnea may not qualify if treatment controls their symptoms and they do not have a qualifying functional restriction.
Another person may qualify when sleep apnea and related conditions cause profound, ongoing limitations despite appropriate treatment.
Does CPAP Count as Life-Sustaining Therapy for the DTC?
The DTC life-sustaining therapy category applies when a person requires therapy that supports a vital function:
-
At least twice per week
-
For an average of at least 14 hours per week
Only time dedicated to administering the therapy and taken away from normal everyday activities can generally be counted.
Does Time Sleeping With CPAP Count?
No. The CRA specifically excludes the time a CPAP machine takes to deliver therapy.
This means that wearing a CPAP mask for seven or eight hours each night does not create 49 or 56 qualifying therapy hours per week.
Travel time, ordinary medical appointments, obtaining medication and general recovery time also generally do not count toward the 14-hour requirement.
Can a CPAP User Still Qualify?
Potentially, but most people will not qualify through life-sustaining therapy based on CPAP use alone.
A person may qualify through another route if sleep apnea or related conditions create a marked restriction in an eligible everyday activity or meet the cumulative-effect criteria.
Other medically required respiratory therapy may also need to be considered separately. The treating practitioner should describe the therapy, the time actively required to administer it and whether it meets the CRA’s criteria.
What Other Sleep Apnea Limitations May Qualify?
Some people may qualify because sleep apnea and related medical conditions severely affect an eligible area of everyday functioning.
Mental Functions Necessary for Everyday Life
Sleep apnea can cause daytime sleepiness, poor concentration, memory problems and slower thinking.
However, ordinary fatigue or difficulty concentrating at work will not necessarily meet the DTC test.
The limitation must generally be severe enough that the person is unable, or takes approximately three times longer, to perform necessary everyday mental functions all or almost all of the time.
Relevant mental functions may involve:
-
Attention and concentration
-
Memory
-
Judgment and problem-solving
-
Planning and completing necessary everyday tasks
-
Understanding verbal and non-verbal information
Cumulative Effect of Significant Limitations
A person who does not have one marked restriction may qualify through significant limitations in two or more eligible categories.
For example, sleep apnea may exist alongside heart disease, mobility problems, mental health conditions or another impairment affecting everyday functioning.
To qualify through cumulative effect, the limitations must generally:
-
Exist in at least two eligible categories
-
Exist together at least 90 per cent of the time
-
Have lasted or be expected to last for at least 12 continuous months
-
Create an impact equivalent to one marked restriction
Life-sustaining therapy can’t be combined with other categories under the cumulative-effect test.
How Do You Apply for the Sleep Apnea Disability Tax Credit?
The person with sleep apnea or their legal representative must complete Part A of Form T2201, Disability Tax Credit Certificate.
A qualified medical practitioner completes Part B and describes the effects of the impairment.
A medical doctor or nurse practitioner can certify all DTC categories. A psychologist may certify limitations involving mental functions.
The Disability Tax Credit application may be completed digitally or by mailing the current paper version of Form T2201.
Focus on Everyday Functioning
A sleep-study report confirms the diagnosis and medical severity of sleep apnea. It may not explain whether the applicant meets the DTC’s functional requirements.
The medical practitioner should clearly describe:
-
The limitations that remain despite CPAP or other treatment
-
Which eligible activities are affected
-
How frequently the limitations occur
-
Whether activities take approximately three times longer
-
When the qualifying restrictions began
-
The effects of related medical conditions
Provide Accurate Treatment Information
The application should explain which treatments have been prescribed, whether they are used consistently and what symptoms remain.
If CPAP use is limited by mask problems, discomfort, dryness, claustrophobia or another medical issue, those concerns should be documented with the treatment provider.
What Does DTC Approval Provide?
The Disability Tax Credit is a non-refundable tax credit. It may reduce the income tax paid by the eligible person or an eligible supporting family member.
It is not a fixed sleep apnea payment and is not paid monthly.
Approval may also provide access to other programs, depending on the person’s age and circumstances, including:
-
The Registered Disability Savings Plan
-
The Canada Disability Benefit
-
The Canada Workers Benefit disability supplement
-
Certain provincial or territorial programs
Can the DTC Be Retroactive?
Potentially. The CRA’s notice of determination identifies the years for which the person is approved.
DTC eligibility may be recognized for previous years, up to a maximum of 10 years from the date the CRA receives the application.
The applicant may authorize the CRA to adjust eligible previous tax returns automatically.
What If a Sleep Apnea DTC Application Is Denied?
The CRA will send a notice of determination explaining why the DTC application was denied.
Common issues may include:
-
The application relies mainly on the sleep apnea diagnosis or sleep-study result
-
CPAP operating hours are incorrectly counted as therapy time
-
The application focuses on an inability to work rather than everyday functioning
-
The 90-per-cent requirement is not addressed
-
The medical practitioner provides brief or general answers
-
Related impairments or cumulative limitations are not explained
Request a Second Review
An applicant may ask the CRA to review its decision and submit new or updated medical information.
The additional evidence should address the specific denial reasons rather than repeat the original application.
File an Income Tax Objection
An applicant may also file a formal income tax objection within 90 days of the date on the notice of determination.
Submitting additional information does not necessarily extend the objection deadline. Review the notice promptly.
DTC vs. LTD and CPP Disability for Sleep Apnea
The DTC, long-term disability and CPP Disability use different eligibility tests.
-
DTC: Focuses on severe and prolonged limitations in everyday activities or qualifying life-sustaining therapy.
-
Long-term disability: Considers whether you can perform your occupation or another suitable occupation under an insurance policy.
-
CPP Disability: Considers whether a severe and prolonged disability regularly prevents substantially gainful work.
A person may qualify for LTD benefits without qualifying for the DTC. A DTC denial also does not determine whether an insurance company should approve a disability claim.

Frequently Asked Questions About Sleep Apnea and the DTC
Does sleep apnea automatically qualify for the Disability Tax Credit?
No. DTC eligibility is based on severe and prolonged functional limitations or qualifying life-sustaining therapy—not the diagnosis alone.
Does severe sleep apnea qualify for the DTC?
Potentially, but medical severity alone is not enough. The applicant must meet one of the CRA’s functional or therapy-based eligibility tests.
Does CPAP use count toward the 14-hour requirement?
The time a CPAP machine takes to deliver therapy does not count. Sleeping with the machine operating is therefore excluded from the 14-hour calculation.
Can sleep apnea qualify through mental functions?
Potentially. The resulting limitation must be severe, prolonged and present at least 90 per cent of the time. Ordinary tiredness or occasional concentration problems are unlikely to meet the test.
Who completes the DTC form?
The applicant or legal representative completes Part A. A qualified medical practitioner completes Part B.
Can the DTC be retroactive?
Potentially. The CRA may approve previous eligibility years, up to a maximum of 10 years from the date it receives the application.
What should you do if the application is denied?
Review the denial reasons and consider submitting new medical information, requesting a second review or filing an objection within the applicable deadline.
