Important: The Canada Revenue Agency (CRA) has changed how many Disability Tax Credit (DTC) applications are submitted in 2026. Applicants should use the current CRA online DTC process or the latest paper version of Form T2201 to avoid delays or rejection.

What changed for DTC applicants?

Since July 14, 2026, applicants generally cannot use the ordinary “Submit documents” function in CRA My Account to send a new Disability Tax Credit application. New applicants should instead use the dedicated online DTC application process through their CRA account or mail the current paper version of Form T2201.

This change applies to new DTC applications. Before submitting documents, confirm that you are using the correct process and the latest form available from the CRA.

The September 8, 2026 T2201 deadline

Beginning September 8, 2026, the CRA will reject T2201 forms created before 2023. This means applicants using an older copy of the form should replace it with the current version before submitting their application.

The September 8 deadline is especially important for applicants who have saved a T2201 form on their computer, received an older copy from a practitioner, or are reusing documents from a previous application. A form that is complete but outdated may still be rejected.

How to check which T2201 version you have

1. Open the saved PDF or paper copy of Form T2201.
2. Look for the form’s creation or revision date and version information.
3. Confirm that the form was created in 2023 or later.
4. If you cannot verify the version, download or request the latest T2201 form from the CRA.
5. Do not submit an older form simply because the information on it is still accurate.

How to apply through your CRA account

Applicants can generally apply online through the CRA’s dedicated DTC application process. Sign in to your CRA account, locate the Disability Tax Credit application service, and follow the instructions to complete the applicant section and provide the required medical information.

Review every answer before submitting. Save confirmation details and copies of any information uploaded or entered online for your records.

What your medical practitioner must complete

A medical practitioner must complete the relevant sections of Form T2201 based on the applicant’s impairment and restrictions. The practitioner’s section should describe the effects of the impairment, how long the restrictions have lasted or are expected to last, and the applicable impairment category.

Ask the practitioner to provide clear, specific information rather than relying only on a diagnosis. Incomplete or general answers can lead to requests for clarification and may delay the CRA’s decision.

Documents to prepare

• The applicant’s personal and tax information
• The current T2201 form, if applying by paper
• Information about the impairment and its functional effects
• Relevant medical records or supporting details requested by the practitioner
• Details about when the impairment began and how long it is expected to continue
• Confirmation records and copies of the submitted application

Mistakes that can delay a DTC decision

• Using the ordinary CRA Account “Submit documents” function for a new DTC application
• Submitting a T2201 form created before 2023 after September 8, 2026
• Leaving applicant or practitioner sections incomplete
• Providing a diagnosis without explaining day-to-day functional restrictions
• Using inconsistent dates or incomplete information
• Failing to keep proof of submission and copies of the completed form

What to do if CRA requests more information

Read the CRA request carefully and note the response deadline. Contact the relevant medical practitioner if additional clarification is needed, then submit the requested information through the method specified by the CRA.

Keep a copy of everything sent and proof of delivery or online submission. If the request is unclear, review the CRA’s official instructions or seek qualified tax assistance before responding.

Key takeaway

The Disability Tax Credit application process is changing in 2026. Since July 14, applicants generally need to use the dedicated CRA online DTC process or mail the current paper form, and from September 8, 2026, the CRA will reject T2201 forms created before 2023. Check your form version early and make sure all applicant and medical practitioner sections are complete.
