The old disability tax credit form stops working on September 8

The Disability Tax Credit is the single most valuable form in the Canadian benefit system, and almost nobody talks about it as a form. That's a problem this month, because the CRA has changed which version of it counts.

Two dates that just changed the process

• July 14, 2026 — the "submit documents" section of your CRA account no longer accepts DTC applications or related documents, unless the CRA specifically asked you for more information on an existing case.
• September 8, 2026 — older versions of Form T2201 (anything printed before 2023) will no longer be accepted. A pre-2023 form submitted after that date isn't corrected or held; the application is rejected and you start over.

Both changes are about the same problem: incomplete and outdated applications clogging a queue that already runs slow. The fix on your side is small — but only if you catch it before you send anything.

If you downloaded a T2201 a few years ago, or your doctor's office keeps a stack of printed blanks, assume it's the wrong version. Check the form date before your practitioner signs it, not after.

The version that always works

The online DTC application in your CRA account is always the current version by definition, and it walks both you and your medical practitioner through only the sections that apply to you. It's the fastest route and the one the CRA is steering people toward.

If paper is the right call, download Form T2201 (2023 or later) fresh from Canada.ca, get it completed and signed by you and a medical practitioner, and mail it to your CRA tax centre.

What the form is actually worth

The DTC itself is a non-refundable credit. For 2026, the federal disability amount is $10,341, which at the new 14% bottom federal rate is worth about $1,448 off your federal tax — plus a provincial credit on top. Because it's non-refundable, it only helps if there's tax to reduce, though it can be transferred to a supporting spouse, parent, or other relative when the person with the disability doesn't need it all.

And once approved, you can go back: up to 10 prior years can be reassessed through a T1 adjustment request. Approvals frequently produce a four-figure retroactive refund.

The bigger reason to file it

The credit is the smaller half. DTC approval is the gate on:

• The Canada Disability Benefit — up to $204.20 a month for approved adults aged 18–64. No DTC, no benefit.
• The Registered Disability Savings Plan — the most generous matched savings account in the country, worth up to $70,000 in grants and $20,000 in bonds over a lifetime. On family income at or below $117,045 in 2026, a $1,500 contribution triggers the full $3,500 annual grant.
• The Child Disability Benefit, the disability supplement in the Canada Workers Benefit, and several deductions and credits keyed to DTC status.

Most of those are income-tested on family net income, so the household number matters more than the individual one — the household income percentile tool shows where a family sits, and the take-home pay calculator shows what a raise or extra hours actually clear once the clawbacks stack.

What to do this week

1. Check the form version before anyone signs it. Pre-2023 is dead on September 8.
2. Apply through your CRA account if you can — it can't be the wrong version.
3. Don't use "submit documents." Since July 14 it won't take a DTC application, and a file sent there may simply go nowhere.
4. Already approved? Nothing to do. This affects new applications and renewals, not existing certificates.

The takeaway

Nothing about who qualifies for the DTC changed — only which paper the CRA will read. But an application rejected on a technicality can cost months, and behind that form sit the CDB, the RDSP, and up to a decade of retroactive credit. If there's a T2201 sitting half-finished on a kitchen table, September 8 is the date to beat.
