Disability Tax Credit
The DTC reduces income tax that individuals with disabilities would otherwise pay and can be transferred (in full or part) to a supporting family member when the claimant’s income doesn’t qualify for the full benefit. Click below to learn more.
DTC Information
We stay current with the CRA’s ever-changing eligibility rules and have cumulatively obtained hundreds of thousands of dollars for our clients. Our fee is based per re-adjusted tax year (rather than by percentage of your refund), ensuring you’ll get more.
Once your disability is certified by a medical practitioner, we’ll submit your documents to the CRA, adjust your tax returns for up to 10 years (depending on medical certification), and claim any additional applicable tax credits.
The DTC is also a gateway for other programs such as the RDSP, CDB, and CWB disability supplement.
Contact us or visit the the CRA for more info.
Remote Tax Filing
We offer secure remote filing at no extra cost! PDF copies of your tax return are available by e-mail or through our online portal. Payment can be made via telephone or e-transfer. We charge a nominal mailing fee if you would like physical copies of your tax returns sent to you.
