TD1AB: 2026 Alberta Personal Tax Credits Return

TD1AB is the Alberta Personal Tax Credits Return. You complete it alongside the federal TD1 so your employer or payer can calculate how much Alberta income tax to deduct from each payment.

What is TD1AB?

TD1AB, the 2026 Alberta Personal Tax Credits Return, is a Canada Revenue Agency form your employer or payer uses to determine the Alberta portion of income tax to withhold from your pay or pension. You claim the Alberta personal amounts that apply to you, such as the basic personal amount and credits for a spouse, dependants, age or disability. It works together with the federal TD1 to set your total tax deducted at source.

TD1AB is a dynamic PDF that the CRA publishes in Adobe XFA format. It does not fill in a web browser, so it will not display in the in-browser editor or quick-fill form here. Download it and open it in Adobe Acrobat Reader to complete the fields, then print and sign it for your employer.

Who files TD1AB?

  • Employees working in Alberta starting a new job
  • Pensioners and payees in Alberta subject to tax withholding
  • Alberta workers whose personal credits change during the year
  • People who claim more than the basic personal amount in Alberta

How to fill out TD1AB

  1. Download the form and open it in Adobe Acrobat Reader, since it is a dynamic PDF that will not fill in a browser.
  2. Enter your name, date of birth, address and social insurance number.
  3. Claim the Alberta personal amounts that apply to you and total them.
  4. Complete the back page if you have more than one payer or want extra tax withheld, then sign the return.
  5. Give the completed TD1AB to your employer or payer; you do not send it to the CRA.
Worth knowing: TD1AB is a dynamic XFA PDF. Open it in Adobe Acrobat Reader to fill it. Give the signed return to your employer or payer, not the CRA.

Frequently asked questions

Do I need the federal TD1 as well?

Yes. TD1AB sets only the Alberta tax deducted. Complete it together with the federal TD1 so both the federal and provincial portions of tax are withheld correctly.

Where does the completed form go?

Give it to your employer or payer, who keeps it on file. You do not send TD1AB to the CRA. Fill in a new one whenever your personal credits change.
