Section A

What's new as of January 1, 2021

The major changes made to this guide since the last edition are outlined.

This guide reflects some income tax changes recently announced which, if enacted as proposed, would be effective January 1, 2021. At the time of publishing, some of these proposed changes were not law. We recommend that you use the new payroll deductions tables in this guide for withholding starting with the first payroll in January 2021.

The federal Basic Personal Amount has been changed to the following:

  • Where NI ≤ $151,978, BPAF = $13,808
  • Where $151,978 < NI < $216,511, BPAF = $13,808 - (NI - $151,978) × ($1,387 / $64,533)
  • Where NI ≥ $216,511, BPAF = $12,421

For 2021, employers can use a BPAF of $13,808 for all employees, while payroll systems and procedures are updated to fully implement the proposed legislation.

If the employer uses a BPAF of $13,808 for its employees, employees with net income above $151,978 can ask for additional tax to be deducted, by completing the form TD1.

The federal income tax thresholds have been indexed for 2021.

The federal Canada employment amount has been indexed to $1,257 for 2021.

The Northwest Territories income thresholds and personal amounts have been indexed for 2021.

Claim codes

You may have to ask your employees or your pensioners to complete a federal and a territorial personal tax credits return using a federal Form TD1 and a territorial Form TD1.

The total personal amount an employee claims on a TD1 form will determine which claim code you use. For 2021, the claim amounts that correspond to the federal claim codes are not the same as the claim amounts that correspond to the territorial claim codes. See Chart 1 and Chart 2.

The claim codes and corresponding amounts do not appear on either the federal or the territorial TD1 form.

Explanation of claim codes

Claim code 0

This code represents no claim amount. If the federal claim code is “0” because the employee is a non-resident, the territorial claim code must also be “0.” This code may also be used if the employee indicated they have more than one employer or payer at the same time and have entered “0” on the front page of Form TD1 for 2021.

Claim codes 1 to 10

You match the total claim amount reported on your employee's or pensioner's TD1 forms with the appropriate claim codes. Then, you look up the tax for the employee's pay under the claim code in the federal and territorial tax tables for the pay period.

Indexing of claim codes amounts

The credits that apply to each federal and territorial claim code have been automatically increased in the tax tables by the indexing factor for the current year. If your employee did not complete the federal and territorial TD1 forms for 2021, you continue to deduct income tax using the same claim code that you used last year.

Due to the December 9, 2019 announcement, legislative changes to the Federal Basic Personal Amount, the Claim Code Chart cannot be produced with ranges, as was previously done. Accordingly, the Federal Claim Code Chart will not be produced with this edition.

Employment income from all sources

On the federal and Territorial TD1 forms, under the heading "Income from other employers or payers," employees can indicate that their expected employment income from all sources will be less than their total claim amount. If an employee states that his or her total expected income will be less than the "Total claim amount" of the TD1 forms, do not deduct any federal or Territorial tax.

However, as an employer, if you know that this statement is false, you must deduct federal and Territorial tax from the salary. Deduct tax according to the claim code that applies to the "Total claim amount" of the TD1 forms.

It is a serious offence to knowingly accept a Form TD1 that contains false or deceptive statements. If you are not sure a statement is true, contact your tax services office for advice.
