Is this guide for you?
Use this guide if you are a payroll software provider or a company which develops its own in-house payroll solution.
This guide has the formulas you need to determine federal, provincial (except Quebec) and territorial income taxes, Canada Pension Plan (CPP) contributions and employment insurance (EI) premium deductions. The formulas also let you calculate payroll deductions for income sources such as commission, pension, bonuses and retroactive pay increases.
The formulas used in this guide to calculate statutory deductions have been approved for purposes of the Income Tax Act, the Canada Pension Plan, the Employment Insurance Act, as well as their related regulations and any amendments proposed to these acts.
For more information on income amounts that are subject to payroll deductions, see the publication T4001, Employers’ Guide – Payroll Deductions and Remittances.
If you have questions about the formulas in this guide, contact your tax services office or tax centre. For the address and telephone numbers of your tax services office or tax centre, see the listings in the government section of your telephone book or visit canada.ca/taxes.

Payroll Deductions Online Calculator
For your payroll deductions, you can use our Payroll Deductions Online Calculator (PDOC). The calculator includes an option to help you make sure that enough Canada Pension Plan contributions and employment insurance premiums have been withheld for full-year employees.
It calculates payroll deductions for the most common pay periods, as well as the applicable province (except Quebec) or territory. The calculation is based on exact salary figures.
PDOC is available at canada.ca/pdoc.
Payroll Deductions Tables
Using the following links, you can download the publications T4032, Payroll Deductions Tables and T4008, Payroll Deductions Supplementary Tables. You can also choose to print only the pages or information that you need. For more information on payroll, see our webpage at canada.ca/payroll.
What's new for July 1, 2023?
This guide reflects some income tax changes recently announced which, if enacted as proposed, would be effective July 1, 2023.
At the time of publishing, these proposed changes were not law. Please refer to the 117th edition for any sections that have not been reproduced. We recommend that you use PDOC, the publication T4032 Payroll Deductions Tables, or the publication T4008 Payroll Deductions Supplementary Tables and the formulas in this guide for withholding, starting with your first payroll in July 2023.
Federal Changes
At the time of publishing, there were no federal changes announced.
Provincial and territorial tax changes
You will find below the provincial and territorial tax changes effective July 1, 2023. The current figures for the most commonly used rates, amounts and claim codes can be found in Chapter 8.
Please note that there is no change for Alberta, British Columbia, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Saskatchewan, Yukon or Outside Canada. For information on Quebec provincial tax, refer to Revenu Québec.
Manitoba
Basic Personal Amount
- On March 7, 2023, the Government of Manitoba announced an increase to the basic personal amount, effective January 1, 2023. Subject to approval by the Government of Manitoba, the basic personal amount will increase from $10,855 to $15,000.
- Since employees have received a lower basic personal amount for the first six months of the year, a prorated basic personal amount of $19,145 will apply for the remaining six months commencing with the first payroll in July.
- The Option 2 personal amounts will not be prorated.
Changes in the guide
A note was added to the LCF and LCP formulas to also allow for users to calculate the labour-sponsored funds credit on an annual basis.
Upcoming Guidance for January 2024
As per Canada Pension Plan Regulations Subsection 5.1 (1), for the year 2024 and each subsequent year, pensionable earnings up to the second earnings ceiling are subject to the second additional CPP contributions.
The new formulas and factors for 2024 were initially published in Appendix 2 of the 116th Edition of the T4127; they have been reproduced in Appendix 1 of this guide. Examples illustrating the new factors have been added in Appendix 2 in order to allow users to test their systems ahead of the legislated implementation, in January 2024. A theoretical Year’s Additional Maximum Pensionable Earnings (YAMPE) and maximum contribution have been used based on the 2023 Year's Maximum Pensionable Earnings (YMPE).

Chapter 4 – Option 1 – Tax Formulas
Step 1 – Formula to calculate annual taxable income (A)
As the formula to calculate the annual taxable income (A) and the explanatory variables have not changed, they have not been reproduced.
Step 2 – Formula to calculate basic federal tax (T3)
As the formula to calculate the basic federal tax (T3) and the explanatory variables have not changed, they have not been reproduced.
Step 3 – Formula to calculate the annual federal tax payable (T1)
As the formula to calculate the annual federal tax and the explanatory variables have not significantly changed, only the changes have been reproduced.
T1 = Annual federal tax deduction, except for employees in Quebec, outside Canada, and in Canada beyond the limits of any province or territory
= T3 – (P × LCF)*
* If the result is negative, enter $0.
Only for employees in Quebec:
T1 = [(T3 – (P × LCF))* – (0.165 × T3)]*
* If the result is negative, enter $0.
Only for employees outside Canada and in Canada beyond the limits of any province or territory:
T1 = [T3 + (0.48 × T3) – (P × LCF)]*
* If result is negative, enter $0.
LCF = The lesser of:
(i) $750;
(ii) 15% of the amount deducted or withheld for the pay period for the acquisition, by the employee,
of approved shares of the capital stock of a prescribed labour-sponsored venture capital corporation
Note:
If the shares are invested in a registered retirement savings plan (RRSP), the amount invested can be used to determine the annual taxable income amount. If you want to calculate the credit on an annual basis, (P x LCF) is replaced by LCF, where LCF is 15% of the amount deducted or withheld for the year for the acquisition, by the employee, of approved shares of the capital stock of a prescribed labour-sponsored venture capital corporation. The maximum LCF credit for the whole year cannot exceed $750.
Step 4 – Formula to calculate annual basic provincial or territorial tax (T4)
As the formula to calculate the annual basic provincial or territorial tax and the explanatory variables have not significantly changed, only the changes have been reproduced.
T4 = (V × A) – KP – K1P – K2P* – K3P – K4P
If the result is negative, T4 = $0.
* For employees that are transferred from Quebec to a location outside Quebec, replace K2P with K2RP
Manitoba
K1P = 0.1080 × TCP
Where:
TCP = The total of personal non‑refundable tax credits amounts reported on Form TD1MB. If Form TD1MB
is not filed, TCP is $19,145.
Step 5 – Formulas to calculate the annual provincial or territorial tax deduction (T2)
As the formula to calculate the annual provincial or territorial tax and the explanatory variables have not significantly changed, only the changes have been reproduced.
T2 = T4 + V1 + V2 – S – (P × LCP)
If the result is negative, T2 = $0.
Only for employees in Quebec:
T2 = $0
Only for employees outside Canada and in Canada beyond the limits of any province or territory:
T2 = $0
Where:
T4 = (V × A) – KP – K1P – K2P – K3P – K4P
V and KP are based on 2023 values for A. See the Rates (R, V), income thresholds (A), and constants (K, KP) for 2023 Table 8.1 in Chapter 8.
Note:
If you want to calculate the LCP credit on an annual basis, (P x LCP) is replaced by LCP. The maximum LCP credit for the whole year cannot exceed the maximum labour-sponsored funds tax credit for the province or territory.
Step 6 – Formula to calculate the estimated federal and provincial or territorial tax deductions (T) for the pay period
As the formula to calculate the estimated federal and provincial or territorial tax deductions for the pay period and the explanatory variables have not changed, they have not been reproduced.

Chapter 4 – Option 1 – Tax Formulas
This chapter only includes the formulas to be impacted or added due to the CPP Regulation Amendment. Based on the 2023 YMPE, the theoretical YAMPE and maximum contribution were calculated and are used for illustrative purposes only.
Step 1 – Formula to calculate annual taxable income (A)
A = Annual taxable income
= [P × (I – F – F2 – F5A – U1)] – HD – F1
If the result is negative, T = L.
Only for employees paid by commission:
A = I1 – F* – F2* – F5A – U1* – HD – F1 – E
If the result is negative, T = L.
* Estimated deduction amounts for the year. For registered retirement savings plan (RRSP) contributions included in F, you will need to find out from your employee paid by commission the estimated or expected annual deduction. We recommend that you caution employees not to exceed their RRSP contribution limit for the year.
F5 = C × (0.0100/0.0595) + C2
Only for employees in Quebec:
F5Q = C × (0.0100/0.0640) + C2
Only for employees paid by commission:
F5* = (0.0100 × (I1 – $3,500.00)**, maximum $631.00 × (PM/12)) + (0.04 × (I1 – ($66,600.00 × (PM/12)))**, maximum $184.00 × (PM/12))
* Estimated annual amount
** If the resulting amount is negative, enter $0.
Only for employees in Quebec:
F5Q * = (0.0100 × (I1 – $3,500.00)**, maximum $631.00 × (PM/12)) + (0.04 × (I1 – ($66,600.00 × (PM/12)))**, maximum $184.00 × (PM/12))
* Estimated annual amount
** If the resulting amount is negative, enter $0.
Chapter 5 – Option 2 – Tax Formulas based on cumulative averaging
Formula to calculate annual taxable income (A)
A = Projected annual taxable income
= [S1 × (I – F – F2 – F5A – U1)] + (B1 – F4 – F5B) – HD – F1
If the result is negative, A = $0.
F5 = C × (0.0100/0.0595) + C2
Only for employees in Quebec:
F5Q = C × (0.0100/0.0640) + C2
Chapter 6 – Canada Pension Plan (CPP)
For the following formulas, round the resulting amount to the nearest $0.01.
Note:
This chapter also outlines the Quebec Pension Plan (QPP) formulas. In addition, the term "location outside Quebec" refers to a province or territory outside Quebec.
To determine second additional CPP contributions for employees receiving salary or wages
C2 = The lesser of:
(i) $184.00 × (PM/12) – D2*;
(ii) (PIYTD + PI – W) × 0.04
W = The greater of:
(i) PIYTD;
(ii) YMPE × (PM/12)
If the result is negative, C2 = $0.
* For employees employed in Quebec, use D2Q instead of D2
To determine second additional CPP contributions – only for employees paid by commission
C2 = The lesser of:
(i) $184.00 × (PM/12) – D2*;
(ii) (GYTD + G – W) × 0.04
W = The greater of:
(i) GYTD;

Chapter 7 – Employment Insurance (EI)
As the formula to calculate the employment insurance premiums and the explanatory variables have not changed, they have not been reproduced.
Chapter 8 – Rates and amounts
This chapter only includes the table to be impacted by the CPP Regulation Amendment. Based on the 2023 YMPE, the theoretical YAMPE and maximum contribution were calculated, and are used for illustrative purposes only.
| CPP/QPP | Year's Maximum Pensionable Earnings (YMPE) | Year’s Additional Maximum Pensionable Earnings (YAMPE) | First Additional Employee and Employer Contribution Rate | Maximum First Additional Employee and Employer Contribution | Second Additional Employee and Employer Contribution Rate | Maximum Second Additional Employee and Employer Contribution* | Year’s Additional Maximum Pensionable Earnings (YAMPE) Before Rounding |
|---|---|---|---|---|---|---|---|
| CPP (Canada except QC) | 66,600.00 | 71,200.00 | 0.0100 | 631.00 | 0.04 | 184.00 | 71,262.00 |
| QPP (QC) | 66,600.00 | 71,200.00 | 0.0100 | 631.00 | 0.04 | 184.00 | 71,262.00 |
* All self-employed workers pay both the employer and employee portions of CPP contributions.
Appendix 2: Example Scenarios
This appendix provides example scenarios that illustrate the impact of the second additional CPP contribution formulas. Note that the theoretical 2023 rates and amounts are used for illustrative purposes.
Note:
Rate ratios imbedded in the formulas are part of the calculation and should not be rounded. The results from formulas are rounded as each parenthesis is resolved (rounding rules for CPP exemption and CPP contribution apply).
Scenario 1
An employee is earning $3,000 per pay period. There are 26 pay periods in the year since this employee is getting paid biweekly.
C, C2, and F5 calculations for the 23rd pay period are as follows:
PI = $3,000.00
PIYTD = $66,000.00
PM = 12
P = 26
D = $3,750.78*
D2 = $0*
* Please see Table 1 for CPP contributions and year-to-date contributions for each pay period.
C = The lesser of:
(i) $3,754.45 × (PM/12) – D
= $3,754.45 × (12/12) – $3,750.78
= $3.67
(ii) 0.0595 × [PI – ($3,500.00/P)]
= 0.0595 × [$3,000.00 – ($3,500.00/26)]
= $170.49
C = $3.67
C2 = The lesser of:
(i) $184.00 × (PM/12) – D2
= $184.00 × (12/12) – 0
= $184.00
(ii) (PIYTD + PI – W) × 0.04
= ($66,000.00 + $3,000.00 – $66,600.00) × 0.04
= $96.00
C2 = $96.00
W = The greater of:
(i) PIYTD;
= $66,000.00
(ii) YMPE × (PM/12)
= $66,600.00 × (12/12)
= $66,600.00
W = $66,600.00
F5 = C × (0.0100/0.0595) + C2
= $3.67 × (0.0100/0.0595) + $96.00
= $96.62

Scenario 2
An employee is earning $3,000 per pay period. There are 24 pay periods in the year since this employee is getting paid semimonthly. The province of employment is Ontario until the 12th pay period. From the 13th pay period, the province of employment is Quebec until the 23rd pay period. For the 24th pay period, the province of employment is Ontario.
C2, and F5 calculations for the 24th period are as follows:
PI = $3,000.00
PIYTD = $69,000.00
PM = 12
P = 24
DQ = $1,846.44*
D = $2,037.84*
D2Q = $96.00*
D2 = $0*
* Please see Table 2 for CPP and QPP contributions, and year-to-date contributions for each pay period.
C2 = The lesser of:
(i) $184.00 × (PM/12) – [(D2Q × (0.04/0.04)) + D2]
= $184.00 × (12/12) – [($96.00 × (0.04/0.04)) + $0]
= $88.00
(ii) (PIYTD + PI – W) × 0.04
= ($69,000.00 + $3,000.00 – $69,000.00) × 0.04
