Taxes and Your Pension

Are you aware of how income tax is applied to your pension? Read on to learn more.

Calculation of Income Withholding Tax

The Income Tax Act specifies that pension income from employer-sponsored pension plans is taxable income.

To calculate the tax amount to be withheld, ATRF uses the formula specified by Canada Revenue Agency (CRA). We also use the information from the last federal and provincial Personal Tax Credits Return (TD1) and Request for Additional Income Tax forms we have received from you, if any.

Because income tax regulations and personal circumstances vary, ATRF does not provide taxation counselling. Please contact your tax adviser or the nearest District Taxation Office of CRA to obtain any tax law interpretations.

If you need to report any changes to us, refer to “Changing Tax Information” below.

Changing Tax Information

Income tax is deducted from each pension payment, with the amount based on the TD1 Canada Revenue Agency Personal Tax Credit Return (or Non-Resident Tax Return) and the TD1 submitted to ATRF with your pension election form.

The TD1 form (obtained from Canada Revenue Agency or can be submitted electronically through MyPension) may be filed with ATRF at any time if your circumstances change; for example, if you start receiving rental income. If you would like additional tax deducted (e.g., if taxable income from other sources does not have tax deducted at source), you can make the request using the Request for Additional Income Tax form.

To change your tax information, you may send a completed tax form to:

  • Alberta Teachers’ Retirement Fund Board
    500 Barnett House 11010 142 ST NW
    Edmonton, AB  T5N 2R1 Canada,
  • Fax it to: (780) 453-3547, or
  • Select the MyPension icon to sign in and make the change on our secure member site.

Income Tax Information Slips (T4A and NR4)

The Canada Revenue Agency (CRA) requires that all income tax information (T4A and NR4) slips are mailed by February 28 of each year. ATRF typically mails them in early February.

Use MyPension to Access Tax Slips

Pension recipients who are registered for MyPension are able to view/print their income tax information slips sooner by accessing the site in early January. Prior year tax slips can also be accessed at any time.

You can also update your communication preferences in MyPension to receive notifications when your tax information is available and indicate if you don’t want to receive a hard copy through the mail.


Your ATRF pension benefit is not affected if you apply for or start to receive Canada Pension Plan (CPP) and/or Old Age Security (OAS) benefits. This is true even if you are receiving the Advance & Reduction Option.

You can find more information about OAS and CPP on the Government of Canada website.
