Starting September 8, 2026, the Canada Revenue Agency no longer accepts versions of Form T2201 (Disability Tax Credit Certificate) printed before 2023. Any new DTC application filed on an older paper form will be returned and must be resubmitted on the current version. Applicants should either use the digital DTC application inside CRA My Account or download the latest paper Form T2201 from Canada.ca before applying. Approved DTC certificates already on file are not cancelled by this rule — only new applications are affected. For 2026, an approved adult claimant in Ontario can reduce combined federal and provincial tax by roughly $1,980, with retroactive adjustments possible for up to 10 prior tax years.
» Why the September 8, 2026 Deadline Matters for You
If you or someone you love lives with a long-term impairment, chances are good you have thought about the Disability Tax Credit at some point. Maybe you printed Form T2201 months ago, half-completed it, and set it aside. Maybe an adult child is helping an aging parent finally apply. Maybe a family doctor mentioned it during a recent appointment.
Whatever brought you here, the timing now matters. The CRA is making two changes to the Disability Tax Credit application process in 2026. The first, on July 14, closed a common online submission channel. The second, on September 8, is the one most people need to act on: the CRA will stop accepting older versions of Form T2201 for any new application. Miss the version, and your paperwork comes back unprocessed. Good news — the fix is straightforward, and this guide walks you through it.
» Quick Start: Pick Your Path
Never approved before. Use the digital DTC application in CRA My Account. The online form is always the current version.
Nothing to do. The rule change affects only new applications; your existing certificate remains valid through its stated expiry.
Treat yourself as a new applicant. Use the current form and consider bringing stronger medical documentation this time.
Confirm you have written authorization, then follow the new-applicant steps. Unused credit can be transferred to you if the person has little taxable income.
» If you have a CRA My Account
Sign in to your CRA My Account, open the digital DTC application, and complete Part A. This route removes any risk of a version-mismatch rejection.
» If you are helping a family member
Confirm authorization first. Once approved, unused credit may be transferred to a supporting spouse, parent, grandparent, or sibling when the person with the disability has little or no taxable income.
» What Actually Changed on September 8, 2026
The Canada Revenue Agency runs the Disability Tax Credit under the Income Tax Act. The credit is a non-refundable federal tax credit, which means it reduces income tax you owe rather than paying you a lump sum. To claim it, a medical practitioner must certify on Form T2201 that you have a severe and prolonged impairment lasting at least 12 months.
Two things changed in 2026. As of July 14, the Submit Documents feature inside CRA My Account can no longer be used to send in a new DTC application or its supporting documents. As of September 8, any paper Form T2201 printed before 2023 is rejected outright. The digital DTC form inside My Account, by contrast, is always the current version. Before signing in, it is worth a moment to check the security of your CRA login first, since impersonation attempts have been on the rise.
Existing approvals are not affected. If your DTC certificate is on file and still within its approval period, nothing needs to be resubmitted.
» Digital vs Paper T2201: Which Route Should You Choose?
For most Ontarians with reliable internet, the digital route wins on almost every measurable dimension. The form is always current, submission is confirmed instantly, and CRA can typically process a digital application faster than a mailed paper one. The medical practitioner receives their portion through the online portal and can complete it without printing, scanning, or couriering anything.
Paper still has its place. Older applicants without CRA My Account access, or people applying on behalf of a family member without a digital sign-in, may prefer the paper route. The key discipline is downloading a fresh copy of Form T2201 from Canada.ca in the same week you plan to submit, so version currency is never in doubt.
| What to compare | Digital (CRA My Account) | Paper Form T2201 |
|---|---|---|
| Form version | Always the current version | Must be downloaded fresh from Canada.ca |
| Processing time | Weeks to a few months | Typically longer than digital |
| Medical Part B workflow | Completed through CRA online portal | Printed, signed, and returned by hand |
| Sept 8 rejection risk | None | High if pre-2023 version used |
| Correction process | In-portal edits before submission | Mail resubmit or CRA request letter |
| Accessibility for low-tech users | Requires CRA My Account sign-in | Familiar, no digital account needed |
» What the DTC Is Worth in 2026 (Federal + Ontario)
A non-refundable tax credit reduces the income tax you owe. It does not act like a monthly benefit payment and it does not create a refund on its own. If the person with the disability has little or no taxable income, unused credit can generally be transferred on line 31800 of the T1 return to a supporting spouse, common-law partner, parent, grandparent, child, or sibling.
An additional supplement of about $6,032 is available for claimants under 18, which can add several hundred dollars more depending on the family situation. If approval comes through this year, up to 10 prior tax years may be reassessed through a T1 Adjustment Request, which can generate meaningful retroactive value where the impairment existed in those earlier years. DTC approval is also the gateway to the Registered Disability Savings Plan and other federal programs. For a broader view, see other CRA benefit payments in 2026.
» Step-by-Step Roadmap: Applying Before and After September 8
- 01Confirm the eligibility categoryThe DTC is available where impairment markedly restricts a basic activity of daily living (walking, feeding, dressing, mental functions, hearing, speaking, elimination, or vision) at least 90% of the time. It is also available where life-sustaining therapy is required at least 14 hours a week, which is how many type 1 diabetes and dialysis claimants qualify.
- 02Get the current formOpen the digital DTC application inside CRA My Account, or download the latest Form T2201 (2023 version or later) from Canada.ca. Do not use a copy printed before 2023.
- 03Complete Part APart A covers your personal information, the tax years you want considered, and consent for the CRA to contact your medical practitioner if more information is needed.
- 04Book the medical practitionerPart B is completed by a qualified medical practitioner, ideally through the CRA online portal. The description of how the impairment restricts daily activities matters more than the diagnosis itself. See our personal tax services for support in preparing the file.
- 05Submit through the correct channelSubmit through the digital DTC application, or mail the current paper form to your CRA tax centre. Do not use Submit Documents in CRA My Account for a new application after July 14, 2026.
- 06Request retroactive adjustmentsOnce approved, file Form T1-ADJ to reassess prior tax years where the impairment was already present, up to 10 years back. The CRA may issue refunds for prior-year tax you overpaid.
» Common Mistakes to Avoid Before the September 8 Deadline
Most rejections and delays come from a small set of avoidable errors. Reviewing this list before you submit typically saves weeks. For a broader look at how to prepare if the CRA takes a closer look, our guide on how to prepare if the CRA takes a closer look covers the mindset.
- »Printing Form T2201 months ago and assuming it is still valid. Always download a fresh copy from Canada.ca the same week you plan to submit.
- »Leaving Part B medical detail vague. Descriptions like patient has anxiety are rarely enough — the practitioner should describe frequency, duration, and the specific daily activity affected.
- »Using the wrong submission channel after July 14, 2026. The Submit Documents feature is closed for new DTC applications; use the digital DTC form or mail the current paper version.
- »Forgetting the 10-year retroactive adjustment. Once approved, request T1-ADJ for prior years where the impairment was already present.
- »Assuming a diagnosis is enough. The CRA decides eligibility based on functional restriction, not the condition name itself.
- »Not exploring transfer of unused credit to a supporting spouse, parent, or grandparent when the claimant has little or no taxable income.
» Frequently Asked Questions
If I already have a disability tax credit approval, do I need to reapply with the new T2201 form?
No. The September 8, 2026 rule applies only to new applications. If your DTC certificate is currently approved and within its stated period, no action is required. When the approval period ends or if you are asked to reapply, use the current form at that time.
What happens if I mail in an old Form T2201 after September 8, 2026?
The CRA generally returns the application unprocessed, and you have to start over on the current version. This typically adds several weeks of delay. To avoid this, download the latest form from Canada.ca just before submitting, or use the digital DTC application in CRA My Account.
How do I download the latest version of Form T2201 from the CRA website?
Visit canada.ca, search for Form T2201, and download the PDF dated 2023 or later. The current version is what the CRA accepts. Confirm the version date printed on the form before completing Part A or booking your medical practitioner.
Does ADHD or an anxiety diagnosis qualify me for the disability tax credit in Canada?
Sometimes. Eligibility is not decided by the diagnosis itself but by how the impairment restricts a basic activity of daily living, including mental functions like memory, problem-solving, and adaptive functioning. A thorough Part B description from a qualified medical practitioner is what typically drives approval.
How long does the CRA take to approve a T2201 application in 2026?
Processing generally takes several weeks to a few months. Digital applications through CRA My Account tend to be reviewed faster than paper submissions. The CRA may write to your medical practitioner for more information, which extends the timeline.
Can I still apply on paper, or do I have to use CRA My Account?
Paper applications remain available. The rule is not that paper is banned — it is that only the 2023 version (or later) of Form T2201 is accepted starting September 8, 2026. Download a fresh copy from Canada.ca and mail it to the CRA tax centre for your region.
How much money does the disability tax credit actually save me in Ontario for 2026?
For 2026, an approved adult Ontario claimant can typically reduce combined federal and provincial tax by roughly $1,980, made up of about $1,448 federal and $530 Ontario. Actual value depends on how much tax you owe, since the credit is non-refundable.
If I get approved this year, can I go back and claim the DTC for prior tax years I missed?
Often, yes. Once the CRA approves your certificate, you can generally request adjustments through Form T1-ADJ for up to 10 prior tax years where the impairment was already present. The CRA reviews each year and may issue refunds for any prior-year tax you overpaid.
