The Canada Revenue Agency (CRA) allows various other medical conditions to qualify for the Disability Tax Credit (DTC) if they are severe, prolonged (lasting at least 12 consecutive months), and significantly affect daily living. This category covers conditions that do not directly fit into specific functional categories like walking, hearing, or vision but still impose substantial challenges.

Examples of qualifying conditions include severe migraines, fibromyalgia, postural orthostatic tachycardia syndrome (POTS), interstitial cystitis, lymphoedema, chronic fatigue syndrome (CFS/ME), multiple chemical sensitivity (MCS), complex regional pain syndrome (CRPS), and post-concussion syndrome. The CRA focuses on how the condition impacts daily activities, rather than solely on the diagnosis.

The DTC offers tax relief, access to programs like the Registered Disability Savings Plan (RDSP), and potential retroactive tax refunds for up to 10 years. A qualified healthcare professional must complete Form T2201 to verify the severity of the impairment.

6 Key Signs of Other Qualifying Medical Conditions

1. Chronic Pain Disorders – Conditions like fibromyalgia or CRPS causing persistent, widespread pain that limits movement and daily activities.
2. Neurological & Cognitive Challenges – Disorders like post-concussion syndrome or multiple chemical sensitivity that impact memory, focus, and cognitive abilities.
3. Severe Fatigue & Weakness – Chronic fatigue syndrome or POTS causing extreme exhaustion and limited endurance, even with minimal activity.
4. Frequent & Unpredictable Episodes – Severe migraines or fainting spells that interrupt daily routines and require extended recovery time.
5. Bladder or Pelvic Pain Syndromes – Conditions like interstitial cystitis leading to chronic pelvic pain and urinary urgency affecting daily life.
6. Swelling & Mobility Limitations – Lymphoedema causing persistent swelling and heaviness in limbs, leading to reduced mobility and discomfort.

If you or a loved one is living with a chronic or rare medical condition that impacts daily functioning, you may be eligible for the Disability Tax Credit. A healthcare provider can assist with completing the necessary forms to help access valuable tax benefits and support programs.
