## What’s Changed Under the Disability Supports Deduction
Starting with taxation years **2024 and after**, Canadian taxpayers with a disability will see **expanded eligibility** for the disability supports deduction (Line 21500). Changes include:
- Recognition of **alternative input devices**, such as specialised keyboards and mice for those with physical or mental impairments.

- Allowances for **digital pen devices** meant for computer use. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- Expenses tied to **memory or organizational aids**, where an individual’s mental functions are affected. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- For vision impairments: adding **navigation devices for low vision individuals**. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- For individuals facing severe impairments (blindness, profound deafness, severe autism, etc.), inclusion of goods/services related to **service animals**.

## Who Qualifies and the Rules to Claim
To benefit:
- You must have a **severe and prolonged impairment** in physical or mental functions. ([canada.ca](https://www.canada.ca/en/revenue-agency/programs/about-canada-revenue-agency-cra/federal-government-budgets/budget-2024-fairness-for-every-generation/disability-supports-deduction.html?utm_source=openai))
- Only the **person with the disability** can claim this deduction. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- Expenses must be incurred in 2024 or later. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- Don’t double-claim: if you already claimed an expense as a medical expense (Line 33099 or 33199), you cannot claim it again under Line 21500. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/disability-deductions-credits.html?utm_source=openai))
- Some expenses require certification from an eligible medical practitioner. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4064/disability-related-information.html?utm_source=openai))
## Practical Example
> Sarah is a software developer who has a serious hand-related impairment. She bought an alternative input device (specialised keyboard) in 2024, and also pays for organizational software to help with cognitive impairment.
>
> Under the new rules, Sarah can use **both** the keyboard and organizational aids under Line 21500, reducing her taxable income. She must ensure she obtains a medical practitioner’s note for the keyboard, and that the software isn't also claimed as a medical expense elsewhere. She’ll calculate the total of eligible items, complete **Form T929**, and file with her 2024 return.
## Action Steps for Eligible Taxpayers
1. **Review receipts/orders** from 2024 onward to identify eligible items (e.g., navigation devices, digital pen, service animal related costs).
2. **Gather medical certification** where required.
3. **Ensure no overlap** with medical expenses elsewhere.
4. **Use Form T929** to compute deduction and record totals.
5. **File in 2025** (for 2024 taxation year expenses).
6. **Stay updated**: watch for any finalized legislation or CRA guidance clarifying eligible amounts. The list may expand or be refined.
## Why This Matters
- These updates can significantly **lower taxable income** for taxpayers with disabilities.
- They recognize the real costs of accessibility tools and support services—costs which were frequently barriers to claiming deductions under older rules.
- Ensuring correct claims now helps avoid audits or re-assessments later.

This change places Canada ahead in recognizing disability-support costs as legitimate, tax-deductible support—essential for financial fairness and equity.
