How to fill out Form T2201, box by box
Tell us about the person with the disability
Person intending to claim the disability amount

If different from the person with the disability, enter the person intending to claim the disability amount. This person must be a supporting family member of the person with the disability (the spouse or common-law partner of the person with the disability, or a parent, grandparent, child, grandchild, brother, sister, uncle, aunt, nephew, or niece of that person or their spouse or common-law partner).
Enter the First name, Last name, Relationship and Social insurance number of that person, and mark Yes or No for Does the person with the disability live with you?
Indicate which of the basic necessities of life (Food, Shelter, Clothing) have been regularly and consistently provided to the person with the disability, and the years for which it was provided.
Provide details regarding the support you provide to the person with the disability (regularity of the support, proof of dependency, if the person lives with you, etc.).
If you and another person support the same dependant, you may split the claim for that dependant. However, the total amount of your claim and the other person's claim cannot be more than the maximum amount allowed for that dependant. If you want to provide more information than the space allows, or another supporting family member would like to add information about the support they provide, use a separate sheet of paper, sign it, and attach it to this form.
As the supporting family member intending to claim the disability amount, confirm the information is accurate and sign on the Signature line. This authorization will not result in automatic adjustments to your previous tax returns.
More rules for Form T2201
The disability tax credit (DTC) is a non-refundable tax credit that helps persons with disabilities or their supporting persons reduce the amount of income tax they may have to pay.
A person may be eligible for the DTC if they have a severe and prolonged impairment in physical or mental functions resulting in a marked restriction. A marked restriction means that, even with appropriate therapy, devices, and medication, they are unable or take an inordinate amount of time in one impairment category, all or substantially all (generally interpreted as 90% or more) of the time.
Mark Yes or No for Are you the person with the disability or their legal representative (or if the person is under 18, their legal guardian)? If no, or more than one person is claiming the disability amount, you will need to send a Form T1-ADJ for each year to be adjusted or a letter with the details of your request(s).
If eligibility for the disability tax credit is approved, would you like the CRA to apply the credit to your previous tax returns? Yes, adjust my previous tax returns for all applicable years. No, do not adjust my previous tax returns at this time.
Once the medical practitioner certifies the form, it is ready to be submitted to the CRA for assessment.

Your next steps. Step 1 - Ask your medical practitioner(s) to fill out the remaining pages of this form. Step 2 - Make a copy of the filled out form for your own records.
