The Government of Canada is urging all Canadians to file their income taxes on time to maintain eligibility for the Canadian Dental Care Plan (CDCP) and other income-tested federal benefits. As of June 2026, the Canada Revenue Agency (CRA) is also preparing to launch automatic tax filing services in fall 2026, a move that could significantly expand CDCP access among lower-income Canadians who currently fall through the cracks.
As of June 2026, the connection between tax filing and dental care access has become one of the most consequential administrative issues affecting dental practices across Ontario and the Greater Toronto Area. The CDCP — now open to all eligible Canadian residents regardless of age — uses household income reported on tax returns to determine both eligibility and co-payment levels. If a patient has not filed their taxes, they cannot access or renew their CDCP coverage, regardless of whether they would otherwise qualify.
Why Tax Filing Matters for CDCP Eligibility
The Canadian Dental Care Plan is an income-tested benefit. To qualify, applicants must have filed their tax return for the relevant assessment year and have an adjusted family net income below $90,000 CAD. The co-payment structure — which ranges from zero co-pay for incomes under $70,000 CAD to partial co-pay for incomes between $70,000 and $90,000 CAD — is calculated directly from the income figures on the applicant's tax return.
This means that non-filers are completely locked out of the program, even if their income would clearly qualify them for full coverage. According to the Government of Canada, adults aged 18 to 55 with household incomes below $70,000 CAD have the lowest levels of CDCP awareness and understanding — and they are also the demographic most likely to have unfiled tax returns.
Employment and Social Development Canada (ESDC) released a statement in April 2026 emphasizing that Canadians must file their income taxes to remain eligible for important income-tested benefits, including the CDCP, the Canada Child Benefit, the GST/HST credit, and provincial programs.
The Automatic Tax Filing Initiative
To address this gap, the CRA is preparing to roll out automatic tax filing services beginning in fall 2026. The initiative targets Canadians with straightforward tax situations — primarily those with single-source income from employment or government benefits — who have historically not filed returns. The CRA will use information it already holds (T4 slips, benefit records, financial institution data) to prepare and file returns on behalf of eligible individuals, with their consent.
This is a significant policy development for the dental sector. The CRA estimates that automatic filing could bring hundreds of thousands of non-filers into the tax system, many of whom would become eligible for the CDCP and other health-related benefits. For dental practices in Toronto, Mississauga, Brampton, Markham, and across Ontario that are already managing CDCP patient volumes, this represents a potential wave of newly eligible patients arriving in late 2026 and early 2027.
Pro Tip: Start preparing now for a potential increase in CDCP-eligible patients this fall. Review your CDCP billing workflows, ensure your front desk team is trained on CDCP preauthorization requirements, and consider adding a question about tax filing status to your new patient intake process.
What Ontario Dental Practices Can Do Now
Educate Patients About the Tax Filing Requirement
Many patients do not understand that tax filing is a prerequisite for CDCP coverage. Dental practices are uniquely positioned to communicate this, since they interact with patients who are already motivated to access dental benefits. A simple notice in your waiting room, on your website, or during appointment confirmation calls can make a meaningful difference.
Consider adding a line to your patient communications: "To maintain your Canadian Dental Care Plan coverage, you must file your income taxes each year. If you have not filed your 2025 return, visit canada.ca/taxes or contact the CRA at 1-800-959-8281."
Update Your Intake Process
When a patient presents CDCP coverage, your front desk team should verify that the patient's coverage is active and current. The renewal period for the 2025-2026 benefit year closed on June 1, 2026. Patients who missed the renewal deadline may have a coverage gap until their new application for the 2026-2027 benefit year is processed. New applications opened on June 2, 2026, and are processed on a rolling basis.
For patients who report that their CDCP coverage lapsed, direct them to the Government of Canada's CDCP application page. The 2026-2027 benefit year is now open to all eligible Canadians, with no age restrictions — a significant expansion from earlier program phases.
Prepare for Preauthorization Volume
CDCP preauthorization remains a significant administrative burden for dental practices. Recent data from Oral Health Group indicates that less than half of dental preauthorization requests submitted under the CDCP are approved on first submission. Practices that invest in accurate coding, thorough clinical documentation, and familiarity with the federal fee schedule will see higher approval rates and fewer claim delays.
Pro Tip: Designate one team member as your CDCP billing specialist. Having a single point of accountability for CDCP claims — from preauthorization submission to follow-up on denials — reduces errors and speeds up reimbursement. This is especially important for practices in the GTA that handle high CDCP patient volumes.
The Broader Access Picture
The CDCP now covers more than 6.3 million Canadians, with 3.4 million renewal applications received for the 2026-2027 benefit year as of June 1. Despite this progress, a utilization gap persists: a significant number of approved CDCP members have not yet visited a dentist. The reasons are complex — limited dental office capacity in some regions, patient awareness gaps, and administrative friction in the preauthorization process all contribute.
For dental practices, this utilization gap represents both a challenge and an opportunity. Practices that streamline their CDCP workflows, communicate proactively with patients about coverage requirements, and prepare for the fall influx of newly eligible patients from automatic tax filing will be best positioned to serve this growing patient population.
The CRA's automatic tax filing initiative represents a meaningful step toward closing the access gap. By removing the tax filing barrier for lower-income Canadians, the government is effectively expanding the pool of patients eligible for federally funded dental care. Ontario practices that recognize this trend early can adapt their operations accordingly.

Frequently Asked Questions
Q: Why do my patients need to file taxes to get CDCP coverage?
The Canadian Dental Care Plan is an income-tested benefit, meaning eligibility and co-payment levels are calculated from the adjusted family net income reported on tax returns. Without a filed return, the CRA cannot verify income eligibility, and the patient cannot access or renew their CDCP coverage.
Q: What is the CRA automatic tax filing initiative?
The Canada Revenue Agency is preparing to launch automatic tax filing services in fall 2026 for Canadians with straightforward tax situations who have not filed returns. The CRA will use information it already holds — such as T4 slips and benefit records — to prepare and file returns on behalf of eligible individuals with their consent. This is expected to help more Canadians access income-tested benefits including the CDCP.
Q: How should my dental practice prepare for more CDCP patients this fall?
Review your CDCP billing workflows, ensure your team is trained on preauthorization requirements and federal fee schedules, consider designating a CDCP billing specialist, and update your patient intake process to verify coverage status and inform patients about tax filing requirements. Practices in Ontario should also monitor the CRA's automatic filing rollout timeline for planning purposes.
