Line 30400 - Amount for an eligible dependant

Line 30400 - Amount for an eligible dependant

You can claim this amount if, at any time in the year, you supported an eligible dependant and their net income from line 23600 of their return (or the amount that it would be if they filed a return) was less than the amount at line 30000 for your basic personal amount (plus $2,687 if they were dependent on you because of a physical or mental infirmity).

If you did not claim an amount on line 30300 of your return, you may be able to claim this amount for one dependant if, at any time in the year, you met all the following conditions:

• You did not have a spouse or common-law partner or, if you did, you were not living with them, supporting them or being supported by them

• You supported the dependant in 2025

• You lived with the dependant (in most cases in Canada) in a home that you maintained

In addition, the dependant must also be one of the following persons by blood, marriage, common-law partnership or adoption:

• your parent or grandparent

• your child, grandchild, brother, or sister under 18 years of age

• your child, grandchild, brother, or sister 18 years of age or older with a mental or physical infirmity

  Notes
  If your dependant usually lives with you when not in school, the CRA considers that dependant to live with you for the purposes of this amount.

  For the purposes of this amount, your child is not required to live in Canada, but they must still have lived with you. For example, you were a deemed resident living in another country with your child. (For more information about deemed residents, see page 4.)

  Situations where you cannot claim the amount for an eligible dependant

  Even if all of the conditions have been met, you cannot claim this amount if:

• The person you want to claim this amount for is your spouse or common-law partner (You may be able to claim an amount for them on line 30300 of your return)

• Another person is claiming the spouse or common-law partner amount on line 30300 of their return for this dependant

• Another person in your household is making this claim (each household is allowed only one claim for this amount, even if there is more than one dependant in the household)

• Another person is claiming the amount on line 30400 of their return for this dependant. If you and another person can both claim this amount for the same dependant (such as in the shared custody of a child) but cannot agree on who will claim the amount, neither of you can make the claim

• You had to pay child support in 2025. You cannot claim an amount at line 30400 for a child you had to make support payments for, except in the following situations:

  • You were separated from your spouse or common-law partner for only part of 2025 because of a breakdown in your relationship and you did not claim any support payments to your spouse or common-law partner on line 22000 of your return. (In this case, you may be able to claim the amount for an eligible dependant on line 30400 of your return, plus any allowable amounts for that child on line 30425 and line 31800 of your return, if any.)

  • You and another person had to make support payments for the child in 2025. Claim an amount on line 30400 only if you and the other person paying support agree that you will be the one making the claim. For more information, go to canada.ca/taxes-support-payments.

Completing your return

Complete Schedule 5, Amounts for Spouse or Common-Law Partner and Dependants, to calculate your claim and give certain details about your dependant.

You can claim the corresponding provincial or territorial non-refundable tax credit that you are entitled to on line 58160 of your provincial or territorial Form 428.

How to claim the Canada caregiver amount

If the eligible dependant is 18 years of age or older and dependent on you because of a mental or physical infirmity, you may be entitled to claim an amount up to a maximum of $8,601 on line 30425.

If the eligible dependant is under 18 years of age at the end of the year and dependent on you because of a mental or physical infirmity, you may claim either:

• $2,687 on line 30500 of your return for each eligible dependant who is your (or your spouse's or common-law partner's) child (see line 30500 on page 33)

• $2,687 in the calculation of line 30400 if the eligible dependant does not meet the definition of child below A child includes a person who is one of the following:

• your (or your spouse's or common-law partner's) biological or adopted child

• your child's spouse or common-law partner

• under your custody and control, and who is wholly dependent on you for support, even if they are older than you

Claims made by more than one person

You cannot split this amount with another person. Once you claim this amount for a dependant 18 years of age or older, no one else can claim this amount or an amount on line 30425 of the return for that dependant.

If you and another person can both claim this amount for the same dependant (such as in the shared custody of a child), but cannot agree on who will claim the amount, neither of you can make the claim.

Supporting documents

The CRA may ask for a signed statement from a medical practitioner showing when the infirmity began and what its duration is expected to be.

For children under 18 years of age, the statement should also show that the child is dependent on others for significantly more assistance in attending to personal needs and care than other children of the same age. Due to the mental or physical infirmity, the dependence on others is expected to last for a long and continuous period of indefinite duration. For more information and examples, see Income Tax Folio S1-F4-C2, Basic Personal and Dependant Tax Credits.

You do not need a signed statement from a medical practitioner if the CRA already has an approved Form T2201, Disability Tax Credit Certificate, for a specified period.
