Autism Disability Tax Credit Guide
A clear guide to DTC approval, Child Disability Benefit (CDB) top-ups, and RDSP (a long-term savings plan) grants for children and adults on the autism spectrum.
CRA Rules
CRA Daily Coping & Social Contact 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.
Autism is looked at under CRA mental functions rules (social contact, daily coping, communication, handling feelings). The CRA looks at the extra one-to-one help needed for daily routines, compared with children or adults the same age.
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
- Serious limit in social contact or daily coping (self-care, safety awareness, routines).
- Needs steady one-to-one watchful help, sensory help, or special routine help.
- Issues are present all year for at least 12 months in a row.
- Can open up to $3,480/yr Child Disability Benefit + up to $90,000 in government RDSP grants & bonds.

Avoiding a No
Why Autism claims get denied
Common mistakes doctors and applicants make on Form T2201 Part B (the medical part).
Sending Only a Diagnosis Report
Sending a school or clinic test report with no link to exact hours of daily help.
Doctor Leaving Out Caregiver Hours
Forms missing the long hours parents spend handling distress, sensory overload, and safety risks.
Thinking Level 1 Autism Cannot Count
Level 1 autism can count when planning, coping, and social limits make tasks take three times as long or seriously limit daily life.
Quick Self-Check
If 2 or more of these fit your life, applying for the DTC may be worth a look:
- ☑Does your child — or an adult — need one-to-one prompts or hands-on help with dressing, bathing, or safety?
- ☑Do social contact or communication barriers limit daily home or community tasks 90% of the time (almost always)?
- ☑Do sensory needs or fixed routines seriously disrupt each day?
- ☑Has the condition lasted more than 12 months?
Notes Your Provider Can Use
How a Registered Social Worker helps
We pull speech therapy notes, OT (occupational therapy) notes, and caregiver notes into a clear daily-life summary so your child's doctor or psychologist can fill in Part B correctly.
Common Questions
Common questions about Autism & DTC
How much past-year money can families get for an autistic child?
Parents can get past-year tax reviews and Child Disability Benefit money back for up to 10 past tax years — often $20,000 to $45,000+ in total, based on tax paid and the child's age.
Can Level 1 autism (once called Asperger's) qualify for the DTC?
Yes. The CRA looks at daily-life effects, not autism level. If daily coping, sensory handling, or goal setting is seriously limited, Level 1 can qualify.
What benefits can open up after an autism DTC approval?
Approval can open up the Child Disability Benefit, RDSP grants/bonds (up to $90,000), provincial help changes (such as ODSP/AISH), and caregiver tax credits.
