National Payroll Institute Updated PF1 Exam Questions and Answers by paul

The CRA form used to adjust payroll income tax withholdings at source for employees who earn commission income and have commission expenses is Form TD1X – Statement of Commission Income and Expenses for Payroll Tax Deductions. The CRA explains that an employee completes TD1X if they receive commission income (or salary plus commission) and want the employer to adjust tax deductions to take commission expenses into account.

This is different from:

TD1, which is the Personal Tax Credits Return used to claim basic/personal credits and determine standard withholding (not commission-expense adjustments).

T777, which is used to claim employment expenses on the employee’s personal tax return (not to reduce payroll withholding at source).

TP-1015.R.13.1-V, which is a Quebec form used to request a reduction of Quebec income tax withholding in specific situations (not the CRA commission-expense at-source form).

Operationally, payroll should keep the TD1X on file and apply it to income tax withholding calculations until the employee updates or replaces it.

The Northern residents deductions (often referred to as the “prescribed zone” deduction on the personal tax return) are not limited to the three territories. While all places in Yukon, Nunavut, and the Northwest Territories are in a prescribed northern zone (Zone A), the rules also designate prescribed northern and intermediate zones in parts of several provinces (for example, parts of British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, and others).

The governing framework is in the Income Tax Regulations, which define prescribed zones using geographic descriptions (latitudes/longitudes) covering areas in multiple provinces, as well as the territories.

From a payroll/HR communications perspective, the key is that this deduction is generally claimed by the individual on their income tax return (it does not change the employer’s province-of-employment withholding rules). Employees who believe they qualify should verify their community’s zone status using CRA’s prescribed zone lists before claiming the deduction.

Step 1 — Gross Taxable Earnings (GTE)

Salary per pay: 49,500 ÷ 24 = $2,062.50

Taxable car allowance: $50.00

Group term life taxable benefit:

Coverage = 2 × 49,500 = 99,000

Monthly premium = (99,000 ÷ 1,000) × 0.62 = 99 × 0.62 = 61.38

Semi-monthly benefit = 61.38 ÷ 2 = $30.69

GTE = $2,143.19

Step 2 — Pensionable Earnings (PE)

PE = $2,112.50 (2,062.50 + 50.00)

Step 3 — Insurable Earnings (IE)

IE = $2,112.50

Step 4 — Net Taxable Income (CRA) (NTI)

RPP = 5% × 2,062.50 = $103.13

Union dues = 2% × 2,062.50 = $41.25

NTI (CRA) = 2,143.19 − 103.13 − 41.25 = $1,998.81

Step 5 — Net Taxable Income (RQ)

$0.00

Step 6 — CPP (base CPP)

Period exemption = 3,500 ÷ 24 = $145.83

Contributory = 2,112.50 − 145.83 = $1,966.67

CPP = 1,966.67 × 5.95% = $117.02

CPP = $117.02

Step 6B — 2nd CPP (CPP2)

CPP2 = $0.00

Step 7 — EI premium

EI = 2,112.50 × 1.63% = $34.43

EI = $34.43

Step 8 — QPIP

$0.00

Step 9 — Federal income tax (CC1, semi-monthly)

$156.10

Step 10 — Alberta income tax (CC1, semi-monthly)

$73.20

Step 11 — Total deductions

Statutory: 117.02 + 34.43 + 156.10 + 73.20 = $380.75

Other: RPP 103.13 + Union 41.25 + United Way 20.00 + Social club 5.00 = $169.38

Total deductions = $550.13

Step 12 — Net pay

Cash pay (salary + car allowance) = 2,062.50 + 50.00 = $2,112.50

Net pay = 2,112.50 − 550.13 = $1,562.37

Bonuses and incentives are treated as taxable remuneration, so they are generally subject to the same core statutory deductions as regular earnings: CPP/QPP, EI, and income tax (and in Quebec, QPIP also applies when the remuneration is subject to EI). The CRA specifically notes that you must deduct EI premiums from bonuses/retroactive pay (up to the annual maximum), and the CRA’s guidance for bonuses/irregular amounts uses tools (PDOC/formulas) that calculate CPP contributions, EI premiums, and income tax on these payments.

In Quebec payroll, remuneration that is subject to EI premiums is generally also subject to QPIP premiums, so bonuses/incentives that are EI-insurable are typically QPIP-insurable as well.

In the Northwest Territories and Nunavut, there is also a statutory territorial payroll tax that employers must withhold/remit where applicable, and the NWT guidance explicitly lists bonuses as part of employment income subject to payroll tax.
