If a disability tax credit application is sitting on your to-do list, the way you planned to submit it has already changed. In mid-June the Canada Revenue Agency announced updates to the DTC application process, and two of them had hard dates that have now passed: 14 July 2026 and 8 September 2026. A third change, announced in the spring, still has no firm date but will matter to anyone whose family doctor is hard to reach.
This is the how-to-file piece. If you want the basics of what the credit is and who qualifies, start with our plain-language guide to the DTC. For how the credit connects to the Canada Disability Benefit, see our 2026 update on the DTC and the CDB.
14 July: the upload channel has closed for new applications
Until now, a common way to get a DTC application to the CRA was the “submit documents” section of your CRA account: fill out the form, scan it, upload it. As of 14 July 2026, that section no longer takes DTC applications or related documents. The CRA is reserving it for one job: sending extra information when the agency asks for it on an existing file. If reviewers need more from you, they will contact you through your CRA account or by mail, and that letter will include a case reference number to quote when you upload.
What to use instead is the online DTC application form inside your CRA account. It is not the same thing as uploading a PDF. The digital form is always the current version, helps you skip the sections you do not need, and lets your medical practitioner complete their part online as well. The CRA says online applications are processed more quickly than paper ones. If filling in a form on a screen does not work for you, the digital route also runs by phone: the CRA’s how-to-apply page says you can have Part A completed for you by a call centre agent or through the automated voice service, once you have confirmed your identity. Phone is a way into the digital form, not a third route of its own. The remaining option is the paper form by mail.
Two mechanics the summer announcement leaves out, and both can get an application sent back. The first is that the digital form runs on a reference number. When you finish Part A you get a reference number on the confirmation page. You give that number to your medical practitioner, who uses it to complete and submit Part B online, and the completed application then goes to the CRA automatically. The CRA says the number is valid for up to 12 months and can be used only once. The second is that you cannot mix the two routes. In the CRA’s words, “Both Part A and Part B must be submitted using the same method,” and it is “unable to process your application if the entire application is not submitted in the same format.” Filling in Part A online and then handing your practitioner a blank paper form does not produce an application the CRA can process. One route looks like a mix and is not: a practitioner without a reference number can still fill in Part B using the CRA’s online tool for medical practitioners, print it, sign it by hand and give it to the patient, who then fills in and signs Part A and mails the completed T2201. That is a paper application throughout, with the online tool only doing the typing.
Two more things worth knowing before you book the appointment. If your medical practitioner charges a fee for completing the form, you pay it, although the CRA says you may be able to claim that fee as a medical expense on lines 33099 or 33199 of your return. Timing matters too. The CRA reviews a DTC application before it assesses the tax return it arrives with, so sending both together can delay your assessment. Send the application first.
Since 8 September: older paper forms no longer count
Paper is still allowed. The form version now matters. Since 8 September 2026, the CRA no longer accepts versions of Form T2201 from before 2023, because the older versions do not meet the updated requirements. Submit an old version now and you will be asked to start again on the current form. That means a new appointment, a new signature from your medical practitioner, and more waiting.
The fix is cheap now and expensive later. Check the version of any T2201 you or your clinic have on hand against what the CRA currently publishes: its how-to-apply page names 23e and 23f as the most recent versions. If what you have is older than 2023, download the current version before your certification appointment. Clinics sometimes keep saved copies of the form, so it is worth telling your practitioner’s office that the old ones stopped being valid on 8 September.
If you have a completed, signed form from before 2023 that has not gone in yet, it is too late to send it. Since 8 September 2026 the CRA no longer accepts pre-2023 versions, so have it redone on the current version, 23e or 23f.
Coming next: a shorter route for some conditions, and more professionals who can sign
The third change has no firm date, and it is the biggest one. The federal Spring Economic Update 2026, released on 28 April 2026, proposed three reforms to DTC certification. For a list of long-lasting conditions where the disability impact is well established, a medical practitioner would still certify that the person has the condition, but would no longer have to fill in the long section on how the impairment affects daily living. The government’s own list runs to more than forty conditions, including dementia, ALS, Down syndrome and cystic fibrosis (Table 3, Spring Economic Update 2026). That change would apply to certifications issued for the 2026 and later tax years. It does not change who qualifies. Finance says the eligibility criteria stay as they are, the CRA keeps its authority to ask for more information to confirm the impairment is severe and prolonged, and anyone approved would still have to tell the CRA in writing if their condition improves in a way that could affect eligibility. What goes away is the paperwork, not the test. The update also proposes expanding who can certify. Podiatrists would be added, for impairments affecting walking that fall within their scope of practice. Three professions already on the list would be allowed to certify more than they can now: occupational therapists could certify impairments affecting eliminating, meaning bowel or bladder function, including under cumulative effects; physiotherapists could certify feeding or dressing, plus cumulative effects across walking, feeding and dressing; and speech-language pathologists could certify feeding or hearing, plus cumulative effects across speaking, feeding and hearing. This one is further out than the rest: it would apply only to certifications issued after 2026, for the 2027 and later tax years. The third proposal, which has had far less coverage, would recognize provincial and territorial public guardians, trustees and curators (public curators, in Quebec) as able to certify, for an adult in their care for property matters, that the person holds a valid certificate of incapacity issued by a health care professional. Where that certification is given, Finance says a qualified medical practitioner would no longer be required to certify the impairment at all, which for some families removes the doctor’s appointment from the process. The CRA would still be able to ask for more information to confirm the remaining eligibility requirements are met. Finance proposes the same for Indigenous Services Canada and Crown-Indigenous Relations and Northern Affairs Canada, for adult dependants in their care for property matters under the Indian Act. Like the streamlined condition list, this one would apply to certifications issued for the 2026 and later tax years. Today, certification runs mainly through doctors and nurse practitioners, with a short list of professions able to certify only specific sections.
For anyone who sees an occupational therapist every month and a family doctor once a year, if at all, that change is practical, not cosmetic. CTV News reported that Dr. Bolu Ogunyemi, president-elect of the Canadian Medical Association at the time, expects the reform to narrow the current gap while cautioning that a significant share of people with disabilities still will not benefit from the credit. In the same report, Rabia Khedr, national director of Disability Without Poverty, called the announcement a step in the right direction but said accessing the credit remains an obstacle because of its stringent medical criteria and lengthy application process, and that more work is needed. The same report carries the association’s own figure on the size of the gap: 84 per cent of people living with disabilities in Canada do not hold a DTC certificate.
These reforms need legislative amendments before they take effect, and Finance Canada says consultations on the draft amendments will take place in due course. Do not wait for them. The current pathway stays open, an approval now is not undone when the new route launches, and if you have been turned down before, you will be able to reapply once the new rules are live.
If you are partway through applying
Nothing about eligibility changed this summer. These changes are about the route in. If your application is already with the CRA, you do not need to do anything; if reviewers want more information, they will contact you with a case reference number and instructions. If your plan was to upload a completed form through “submit documents,” that route closed on 14 July: move to the online application, or mail the paper form (current version) to your tax centre.
Why the paperwork is worth the trouble
The DTC is a gateway credit. Approval lowers the tax you pay, can be claimed for up to 10 past years in which you were eligible and did not claim, and opens the door to the Registered Disability Savings Plan and the Canada Disability Benefit, which pays up to $204.20 per month for the July 2026 to June 2027 period. The retroactive part has a switch on it. The application form asks whether you want the CRA to adjust your previous returns. If you do not check that box, you have to ask the CRA in writing afterwards, or change the returns yourself. If the application has felt like too much on top of everything else, the summer’s message is simple: the online route is now the front door, the old paper forms have stopped counting, and an easier certification path is coming for some conditions.
The dates once more. Since 14 July, new applications no longer go through “submit documents.” Since 8 September, only 2023 or later versions of Form T2201 count. And later this year, watch for the regulations that bring the shorter certification route and the wider list of certifiers into force.

Frequently asked questions
Can you still upload a disability tax credit application through ‘submit documents’ in your CRA account?
No. As of 14 July 2026 the submit documents section of your CRA account no longer takes DTC applications or related documents. The CRA is reserving it for sending extra information when the agency asks for it on an existing file. What to use instead is the online DTC application form inside your CRA account, and the remaining option is the paper form by mail.
Can you fill in Part A of the DTC application online and Part B on paper?
No. The CRA says “Both Part A and Part B must be submitted using the same method,” and that it is “unable to process your application if the entire application is not submitted in the same format.” With the digital form, you get a reference number when you finish Part A, and your medical practitioner uses it to complete and submit Part B online. The CRA says the number is valid for up to 12 months and can be used only once.
Can you still send an older paper Form T2201?
Only if it is a 2023 or later version. Since 8 September 2026 the CRA no longer accepts versions of Form T2201 from before 2023, because the older versions do not meet the updated requirements. The CRA’s how-to-apply page names 23e and 23f as the most recent versions. A completed, signed form from before 2023 that has not gone in yet has to be redone on the current version.
What changes has the federal government proposed for disability tax credit certification?
The Spring Economic Update 2026, released on 28 April 2026, proposed three reforms. For a list of more than forty long-lasting conditions where the disability impact is well established, a medical practitioner would no longer have to fill in the long section on how the impairment affects daily living. More professionals would be able to certify, including podiatrists for impairments affecting walking, and provincial and territorial public guardians and trustees would be able to certify, for an adult in their care for property matters, that the person holds a valid certificate of incapacity. Finance says the eligibility criteria stay as they are and the reforms need legislative amendments, and the post reports no firm date.
Why is the disability tax credit worth the paperwork?
Approval lowers the tax you pay, can be claimed for up to 10 past years in which you were eligible and did not claim, and opens the door to the Registered Disability Savings Plan and the Canada Disability Benefit. The application form asks whether you want the CRA to adjust your previous returns, and if you do not check that box you have to ask the CRA in writing afterwards or change the returns yourself. This is general information, not tax advice, so confirm the specifics of your own file with the CRA.
