TD1AB Form

What is Form TD1AB?

Form TD1AB is the Alberta Personal Tax Credits Return, published by the Canada Revenue Agency (CRA). The form states its purpose: "Your employer or payer will use this form to determine the amount of your provincial tax deductions." It is filled out based on the best estimate of the person's circumstances.

The blank on this page is the "2026 Alberta Personal Tax Credits Return", edition TD1AB E (26).

Who fills out Form TD1AB?

The form is for people who have income in Alberta when one of the situations it lists applies, for example when they have a new employer or payer, or when they want to change the amounts they claimed before. The CRA's page on Form TD1 says that all individuals in Alberta claiming more than the basic personal amount must fill out the provincial form TD1AB, and that a new TD1 form is not needed every year unless there is a change to the personal tax credit amounts.

What is on the form?

After the person's name, date of birth, address and social insurance number come the lines of the claim:

1. Basic personal amount
2. Age amount
3. Pension income amount
4. Disability amount
5. Spouse or common-law partner amount
6. Amount for an eligible dependant
7. Caregiver amount
8. Amount for infirm dependants age 18 or older
9. Amounts transferred from your spouse or common-law partner
10. Amounts transferred from a dependant
11. Total claim amount: lines 1 to 10 added together

The form prints the conditions for each of these amounts. Partial claims for the age amount, the caregiver amount and the amount for infirm dependants are worked out on a separate worksheet, Form TD1AB-WS, which the person keeps and does not give to the employer or payer.

Page 2 has sections for a person with more than one employer or payer at the same time and for a person whose total income for the year will be less than the total claim amount. To have more tax deducted at source, the form refers to the section "Additional tax to be deducted" of the federal Form TD1.

Signing and handing in

The person certifies that the information given on the form is correct and complete, signs and dates it, and gives it to the employer or payer. The CRA tells employers and payers to keep the completed forms with the individual's records and not to send the CRA a copy.
