T2201 Disability Tax Credit Application Form: What Changes on September 8, 2026

From September 8, 2026, the Canada Revenue Agency will no longer accept pre-2023 versions of Form T2201, the Disability Tax Credit Certificate. If a practitioner already completed an older copy for you, download the current version from canada.ca, confirm the form date, and check your submission route before you send anything.

Two CRA changes landed in 2026 and both affect how a T2201 reaches the agency. One closed a submission channel a lot of applicants had been using. The other retires every version of the form printed before 2023. Together they mean a file assembled last year may no longer be sendable the way you planned.

This guide covers what changed, who fills in which part of the form, how the online route differs from paper, and what the credit is worth once the CRA approves you. Every figure below comes from canada.ca, and nothing here promises approval, which is always the CRA decision.

What is changing for Form T2201 on September 8, 2026?

From September 8, 2026, the CRA stops accepting older versions of Form T2201. Only the 2023 version or later stays valid. Paper applicants must download the current form from the CRA form page and mail it to their tax centre. Check the version date on the form before your practitioner signs it.

That date is 13 days from August 26, 2026, which is short notice if a practitioner appointment sits between you and a signature. The risk is quiet rather than dramatic. A form printed in 2021 still looks like a T2201, still has a Part A and a Part B, and gives no warning that it belongs to a retired generation.

The second change came earlier in the year and it removed a route people had grown used to. Both are set out on the CRA tax tip page, Help speed up your disability tax credit application.

Can you still send a DTC application through submit documents?

No. Since July 14, 2026, the submit documents section of a CRA account can no longer be used to send Disability Tax Credit applications. The one exception is when the CRA has specifically asked you for more information. In that case only, the tool remains the right place to upload what the agency requested.

This matters because submit documents was the fallback for anyone who had a signed paper form and wanted to avoid the mail. That shortcut is gone. If your practitioner hands you a completed paper T2201 today, the mail route to your tax centre is the way it travels, and the form has to be a 2023 version or later.

The distinction to hold onto is between an application and a follow-up. An application is the first submission of the certificate. A follow-up is the CRA writing to you and naming what it still needs. Only the second one belongs in submit documents now.

What is the difference between Part A and Part B of Form T2201?

Part A is the applicant section. The person with the impairment, or a supporting family member claiming the credit, completes it. Part B is the certification section, and only a medical practitioner can complete it. The practitioner describes the effects of the impairment rather than simply naming a diagnosis.

That distinction between effects and diagnosis is where most weak applications are lost. A condition name tells the CRA nothing about how long it takes someone to dress, whether they can be left alone, or how often therapy is needed. The form asks about function, so the answer has to be about function.

Part A also decides who the credit follows. If the person with the impairment owes little or no tax, the amount can move to a supporting spouse, partner or family member, and that intention belongs in Part A rather than being sorted out later.

What should you gather before you start Form T2201?

Gather the current form, your identification details, the name of the practitioner who will certify Part B, and a plain record of how the impairment affects daily functions. Doing this before the appointment gives the practitioner something concrete to certify instead of a blank page and a short consultation.

If you would rather not assemble that on your own, our team walks Quebec families through it, and you can start an application with us instead of working from a blank form.

Should you apply online or on paper?

The online DTC application in a CRA account is processed faster than paper, so it is the default choice when you can use it. Paper applicants must download the latest 2023 or later Form T2201 and mail it to their tax centre. Both routes still need a practitioner to certify Part B.

Neither route removes the practitioner from the process. The difference sits in how the paperwork travels and how the file opens, not in who decides whether the impairment qualifies.

The current form always sits on the official Form T2201 page at canada.ca. Download it the day you need it rather than reusing a copy saved in a folder, since a saved copy is exactly how a pre-2023 version ends up in an envelope.

Who can certify Part B of Form T2201?

Only a medical practitioner can complete Part B. Which practitioner depends on the impairment category being certified, and Form T2201 sets out that mapping on the form itself. Check it before booking, because a certification signed by the wrong type of practitioner for that category may not be accepted.

Practitioners are allowed to charge for completing the form. That fee is a medical expense, claimable on line 33099 or line 33199 of the return, so keep the receipt with your tax papers rather than treating it as a sunk cost.

Give the practitioner the specifics before the appointment. How much longer a task takes than it would for someone without the impairment, what supervision is needed, how often therapy happens in a week. That is the vocabulary Part B is written in, and it is far easier to supply it than to expect it to be reconstructed in a fifteen minute visit.

How much is the disability amount worth once your T2201 is approved?

For the 2025 tax year the disability amount is $10,138 for someone 18 or older. Children under 18 can add a supplement of $5,914, for a combined $16,052. The federal non-refundable rate is about 15%, so the adult amount reduces federal tax by roughly $1,500.

Non-refundable is the word that trips people up. The credit lowers tax owed, and anything left over is not paid out as a refund. That is why transferring an unused amount to a supporting person often matters more than the headline figure.

Approval can also reach backwards. The retroactive window runs up to 10 years, and the amounts differ by year, as set out on the CRA page on claiming the disability tax credit.

The under 18 supplement is reduced if, in the same year, someone claimed child care expenses on line 21400 or attendant care expenses on line 33099 or line 33199 for the child, or the child claimed attendant care expenses on line 21500 or line 33099. Provincial and territorial amounts exist as well and vary by province, so treat the federal figures above as one part of the picture.

Our retroactive DTC calculator is the quickest way to see what a 10 year window could be worth in your situation before you commit to the paperwork.

What happens if you send an old version of Form T2201 after September 8, 2026?

The CRA will not accept it. From September 8, 2026, only the 2023 version of Form T2201 or later stays valid, so an older certificate cannot be processed as an application. The practical cost is a repeat visit to your practitioner, because Part B has to be certified again on the current form.

None of the amounts above are reachable while the certificate itself is being turned away over a version number. The people most exposed are the ones furthest along: someone who printed the form in the spring, waited weeks for an appointment, and now holds a signed certificate. Look at the form before you seal the envelope.

If you are unsure which version you are holding, the safest move is also the cheapest one. Download a fresh copy from canada.ca, compare it against what you have, and only then decide whether the signature you already collected still counts.

What happens after the CRA approves your T2201?

Approval unlocks two things. You claim the disability amount on your return, on line 31600 for yourself or line 31800 when a dependant transfers it. Approval is also required to open and maintain a Registered Disability Savings Plan, which is the step most families underuse after a successful application.

Several benefits sit behind the same approval. The child disability benefit pays up to $3,480 a year, or $290.00 a month per eligible child, from July 2026 to June 2027, and requires eligibility for both the Canada child benefit and the DTC. That amount begins to be reduced once adjusted family net income passes $82,847, by 3.2% of the excess for one eligible child and 5.7% for two or more.

The Canada Disability Benefit is a separate and newer program. From July 2026 to June 2027 the maximum is $204.20 a month, based on the 2025 return, up from $200 a month in the previous period. A fixed $150 lump sum supplemental payment starts in Fall 2026 to help offset the cost of obtaining the DTC, and no application is needed for it. The Canada workers benefit disability supplement is worth up to $843 for the 2025 tax year.

The savings plan is the part worth acting on early, since contributions attract government grants and bonds over time. If approval has already landed, opening an RDSP is the natural next move rather than something to revisit at year end.

Frequently asked questions

Where do I download the current version of Form T2201?

Download it from the CRA form page on canada.ca, which always carries the current version. Check the version date printed on the form before your practitioner completes Part B, because from September 8, 2026 the CRA no longer accepts any version printed before 2023.

What happens if I submit an old version of Form T2201 after September 8, 2026?

The CRA will not accept it, so the application does not move forward. You would need to download the current form and have a medical practitioner certify Part B again. If your practitioner completed an older copy this summer, check the version date now rather than after you mail it.

Can I still upload my DTC application through submit documents in my CRA account?

No. Since July 14, 2026 the submit documents section can no longer be used to send Disability Tax Credit applications. The only exception is when the CRA has specifically asked you for more information. In that situation, upload exactly what the agency requested and nothing else.

How far back can a Disability Tax Credit claim go?

The retroactive window runs up to 10 years. If the CRA approves your certificate for earlier years, you can ask to adjust those returns. For the 2016 tax year the disability amount was $8,001, and it has risen each year since, reaching $10,138 for the 2025 tax year.

Do I need the Disability Tax Credit to open an RDSP?

Yes. DTC approval is required to open and maintain a Registered Disability Savings Plan, so the T2201 is the gateway document for that account. Families often treat the credit as the finish line when it is really the step that unlocks the savings plan behind it.

Can I claim the fee my practitioner charged for completing the form?

The fee a medical practitioner charges to complete Form T2201 can be claimed as a medical expense on line 33099 or line 33199 of your return. Keep the receipt. Bear in mind that medical expenses are subject to the usual thresholds, so the fee is not refunded directly.

Is the disability amount refundable?

No. The DTC is a non-refundable credit, so it reduces tax owed but any excess over your tax bill is not paid out. That is why a transfer to a supporting spouse, partner or family member matters when the person with the impairment owes little tax.
