Physical & Cumulative Functions
Chronic Pain, Fibromyalgia & Arthritis Disability Tax Credit Guide
Learn how chronic pain, fibromyalgia, arthritis, and mobility limits meet CRA physical or cumulative restriction rules.
CRA Rules
CRA Walking, Dressing & Cumulative Restrictions Rules
How the Canada Revenue Agency (CRA) (the federal office that handles taxes and benefits) reviews who may qualify under Section 118.3 of the Income Tax Act.
Physical impairments (arthritis, fibromyalgia, spinal injuries, neuropathy) qualify under specific physical activities (walking, dressing, feeding, eliminating) OR under 'Cumulative Restrictions' where 2 or more activities combined equal a 90% restriction.
CRA staff do not approve DTC forms based on diagnosis names alone. They look for clear notes showing that daily-life limits are severe and lasting (at least 12 months in a row).
Main Rules to Meet
- Marked restriction in walking (takes three times as long or requires mobility aids to walk 100 meters).
- OR marked restriction in dressing, feeding, or preparing meals.
- OR Cumulative Restrictions: 2 or more daily activities restricted at least 90% of the time when combined.
- Condition must be severe and prolonged (12+ consecutive months).

Avoiding a No
Why Chronic Pain & Physical Impairments claims get denied
Common mistakes doctors and applicants make on Form T2201 Part B (the medical part).
Only Checking One Activity Box When Cumulative Fits Better
Failing to use the 'Cumulative Restrictions' section when walking AND dressing are both moderately impaired.
Not Quantifying Walking Distance and Time
Stating 'has trouble walking' without specifying that walking 100 meters takes 15 minutes or causes severe pain.
Assuming Fibromyalgia Isn't Recognized by CRA
CRA recognizes fibromyalgia when functional limitations in walking, dressing, or cumulative areas are documented.
Quick Self-Check
If 2 or more of these fit your life, applying for the DTC may be worth a look:
- ☑Does walking 100 meters take three times as long as average or require a cane, walker, or frequent rests?
- ☑Does dressing, bathing, or meal prep require physical assistance or adaptive equipment?
- ☑Do pain and fatigue combined restrict multiple daily activities 90% of the time?
- ☑Has chronic pain persisted for at least 12 consecutive months?

Common Questions
Common questions about Chronic Pain & Physical Impairments & DTC
Does Fibromyalgia qualify for the Disability Tax Credit in Canada?
Yes. Fibromyalgia qualifies when chronic pain, fatigue, and mobility restrictions markedly impair walking, dressing, or cumulative daily activities 90% of the time.
What are 'Cumulative Restrictions' under CRA rules?
Cumulative Restrictions allow you to qualify if you have moderate restrictions in 2 or more daily activities (e.g. walking AND mental functions/fatigue) that together equal a marked 90% restriction.
Can I qualify if I use a cane or walker?
Yes. Using mobility aids or taking three times as long to walk 100 meters is primary evidence of a marked restriction in walking under CRA rules.
