The Canada Revenue Agency announced changes to how Canadians apply for disability tax credits, effective July 14, 2026. The shift to online applications aims to reduce processing delays and help eligible Canadians access tax relief faster. The DTC remains one of Canada’s most valuable but underused tax measures, with hundreds of thousands of eligible people never applying.
What’s Changing in July and September
Starting July 14, 2026, the CRA will stop accepting applications through the “submit documents” section in online accounts. Instead, applicants must use other online options or submit by mail. Older versions of paper applications will no longer be accepted starting September 2026. The CRA says it will contact applicants directly through online accounts or by mail if additional information is needed.
Why Online Applications Matter
The CRA urges taxpayers to apply online whenever possible. Online submission allows both applicants and their medical practitioners to access the form directly, which reduces delays. Paper applications take longer to process. By moving to digital channels, the CRA aims to validate information more quickly and process applications faster than traditional mail options.
What the Disability Tax Credit Covers
The DTC is a non-refundable federal tax credit that reduces income tax owed by people with severe, prolonged impairments or their supporting family members. The federal disability amount is up to $10,138, with an additional supplement of up to $5,914 for those under 18. Most provinces add their own disability amount on top. The credit can be claimed retroactively for up to 10 years, which can produce a meaningful one-time refund.
A Gateway to Other Programs
DTC approval unlocks access to several other government programs and benefits. If you have little or no tax payable, the credit can be transferred to a spouse, common-law partner, or other relative so the household still benefits. The CRA estimates hundreds of thousands of eligible Canadians have never applied for the credit, making it one of the most underused tax measures in Canada. Applicants can check eligibility and apply through CRA’s My Account portal.
Final Thoughts
The CRA’s shift to online disability tax credit applications takes effect July 14, 2026, with paper forms phased out by September. Eligible Canadians should apply online to access faster processing and potential retroactive refunds worth thousands of dollars.
