This guide gives you basic information to fill out T4 slips for your employees. T4 slips are used to report an employee’s income, deductions and other information required by law.

What's new

The Canada Revenue Agency (CRA) has outlined major tax changes and improvements to services below. The CRA has noted changes to income tax rules, including those that were announced, but that were not yet law when this guide was published. If they become law as proposed, they will be effective for 2023 or as of the dates given. You will find more information about some of these changes throughout the guide.

Mandatory electronic filing of returns

The threshold for mandatory electronic filing of income tax information returns for a calendar year has been lowered from 50 to 5 for information returns filed after December 31, 2023. For the latest information about the penalty for not filing information returns over the Internet, go to What happens if you file using the wrong method. You may also subscribe to the CRA’s email distribution list about the electronic filing of information returns at Canada Revenue Agency electronic mailing lists.

Electronic remittance or payments above $10K

As of January 1, 2024, payments or remittances to the Receiver General of Canada should be made as an electronic payment if the amount is more than $10,000. Payers may face a penalty, unless they cannot reasonably remit or pay the amount electronically. For more information, go to Payments to the CRA.

Step 1 – Determine if you have to file a T4 slip

Most amounts paid to an individual by an employer are referred to as remuneration. You have to fill out a T4 slips to report the following:

You must also file a T4 slip if any of the following apply:

You have to report income on a T4 slip for the year during which it was paid, regardless of when the services are performed, or if the employee is deceased. For example, you pay your employee in January 2023 for income they earned in December 2022. You will have to report that income on their T4 slip for 2023 since that is the year it was paid.

Do not file a T4 slip if:

For more information on the T4A‑RCA return, go to T4A-RCA.

To see guides, forms, interpretation bulletins, and information circulars the CRA refers to throughout this guide, go to Forms and publications.

If your business amalgamates

The requirement to file a T4 slip will depend on whether or not the predecessor’s company(ies) remittance balance is transferred to the payroll deduction account of the successor company(ies).

Balance is moved to the successor’s Business number (BN)

If the remittance balance is moved to the successor’s payroll deduction account:

Balance is not moved to the successor’s Business number (BN)

If the remittance balance is not moved to the successor’s payroll deduction account:

If you have branch offices

If one of your branch offices has sent in CPP contributions, EI premiums, and income tax deductions under a separate account that only that branch uses, file the T4 information return of that branch as a separate return.

Retiring allowances

A retiring allowance (also called severance pay) is an amount paid to officers or employees when or after they retire from an office or employment, in recognition of long service, or for the loss of office or employment.

For information about what is and is not a retiring allowance, how to calculate deductions for retiring allowances, and how to determine the amount of retiring allowance that is eligible for transfer, go to Retiring allowances, and Income Tax Folio S2‑F1‑C2, Retiring Allowances.

If you paid a retiring allowance to a non‑resident of Canada, do not report it on a T4 slip. Instead, fill out an NR4 slip, Statement of Amounts Paid or Credited to Non‑Residents of Canada. For more information, go to Rendering services in Canada.

For more information, go to:

Deceased persons

If an employee died during the year, you have to file a T4 slip for any income you paid to the employee during the year.

Do not report any amounts you paid as a death benefit to a surviving spouse or common-law partner, or an heir on a T4 slip. Death benefits are reported on a T4A slip. For more information about reporting a death benefit, go to Distribute the slips.

Certified non‑resident employers

Certain certified non‑resident employers are not required to file a T4 slip to qualified non-resident employees. For more information, go to Non-resident employer certification.

Employees outside Canada

If you pay CPP on behalf of your employee who is working outside Canada, for all or part of the year, you have to prepare a T4 slip. For more information, go to Box 29 – Employment code and Box 10 – Province of employment.

Step 2 – Determine the due date

Due date

For most people, the 2023 T4 filing due date is February 29, 2024.

You have to give your employee their T4 slip and file your T4 return with the CRA on or before the T4 filing due date. The CRA considers your T4 return to be filed on time if it is received or if it is postmarked by the due date.

T4 returns filed by a service bureau

If a service bureau files a T4 return for you, you are still responsible for the accuracy of the information, for any balance owing, and for filing on time.

If your business stops operating, or a partner, or the sole proprietor dies

Fill out and file all T4 slips and the T4 Summary using electronic filing methods, or on paper, within:

If you are filling the T4 return by paper, mail the return to the address provided on the T4 Summary.

When an employee leaves

When an employee stops working for you, the filing due date does not change. For more information, go to When an employee leaves.

Exception

If the due date falls on a Saturday, Sunday, or public holiday recognized by the CRA, your T4 return is due the next business day. For more information, go to Payroll.

Late filing penalty

The CRA may charge you a penalty if you file your T4 information return late. The penalty is based on the number of T4 information returns you filed late. The amount of the penalty is calculated based on the below chart. The minimum penalty is $100.

For example, if you file 100 T4 returns and 100 T4A returns late, the CRA would assess two late filing penalties: one for the T4 returns and another for the T4A returns.

The late filing penalty is recalculated if T4 information returns are added or cancelled. The recalculation is based on the updated count of late T4 information returns and the number of days they are late. A new notice of assessment will be sent to you. For T4 information returns, the CRA has an administrative policy that reduces the penalty that it assesses so it is fair and reasonable for small businesses.

Penalties for failure to file returns on time
Number of T4 slips filed late Penalty per day
Maximum
penalty
1 to 5 N/A $100 set penalty
6 to 10 $5 $500
11 to 50 $10 $1,000
51 to 500 $15 $1,500
501 to 2,500 $25 $2,500
2,501 to 10,000 $50 $5,000
More than 10,000 $75 $7,500

Third-party civil penalties

Tax legislation contains various measures to encourage compliance, including penalties for a third-party who counsels others to file their returns based on false or misleading information, or who knowingly accepts false information provided by their clients for tax purposes.

Interest

If you do not pay an amount owing, the CRA may apply interest from the day your payment was due. The interest rate the CRA uses is updated every three months, based on prescribed interest rates. Interest is compounded daily. The CRA also applies interest to unpaid penalties. For the prescribed interest rates, go to Prescribed interest rates.

Cancel or waive penalties or interest

The CRA administers legislation, commonly called taxpayer relief provisions, that allows the CRA discretion to cancel or waive penalties or interest when taxpayers cannot meet their tax obligations due to circumstances beyond their control.

The CRA’s discretion to grant relief is limited to any period that ended within 10 calendar years before the year in which a request is made.

For penalties, the CRA will consider your request only if it relates to a tax year or fiscal period ending in any of the 10 calendar years before the year in which you make your request. For example, your request made in 2023 must relate to a penalty for a tax year or fiscal period ending in 2013 or later.

For interest on a balance owing for any tax year or fiscal period, the CRA will consider only the amounts that accrued during the 10 calendar years before the year in which you make your request. For example, your request made in 2023 must relate to interest that accrued in 2013 or later.

You or your authorized representative can make a request to cancel penalties or interest online using the CRA My Account, My Business Account or Represent a Client services by selecting "Request relief of penalties and interest" under "Related services." Alternatively, you can fill out Form RC4288, Request for Taxpayer Relief – Cancel or Waive Penalties and Interest, and send it online using My Account, My Business Account or Represent a Client by selecting the "Submit documents" service; or by mail to the designated office, as shown on the last page of the form, based on your place of residence.

For more information about how to submit documents online, go to Submit documents online. For more information about relief from penalties or interest and the related forms and publications, go to Cancel or waive penalties or interest.

Step 3 – Consider your T4 return filing method

All T4 returns should be filed electronically to avoid the delays that may occur in processing paper returns.

You must file T4 returns electronically if you file more than 5 T4 slips after December 31, 2023 or 50 T4 slips if you file before January 1, 2024.

If you have more than one payroll deduction account, you have to file a separate T4 return for each account.

Online

You can file T4 returns online using Web Forms or Internet File Transfer if you have a web access code.

You can file your T4 returns without a web access code using our online services at:

If you are already registered for the CRA’s online services, you can log in using your CRA user ID and password or the Sign‑In Partner option.

If you are not registered, you can register by selecting CRA register.

If you file T4 returns electronically, you must not send a paper copy of the T4 slips or T4 Summary to the CRA.

Web Forms

You can file up to 100 slips using Web Forms.

Web Forms lets you do all of the following:

If you are not using My Business Account (MyBA) or Represent a Client (RAC), you must log into Web Forms using both of the following:

Note

A security enhancement was added to the application to mask the first six digits of an employee’s SIN.

Internet file transfer (XML)

You can use third-party software to submit an XML file of up to 150 MB online (third-party software will automatically create the XML file). If you are not using commercial software you must create your own XML file.

For help with filing or amending a T4 return using Internet File Transfer, contact one of the following:

If you are not using MyBA or RAC, you must sign in the Internet file transfer application using both of the following:

For more information about filing T4 returns using Web forms or Internet file transfer, as well as, getting your web access code, go to Filing Information Returns Electronically (T4/T5 and other types of returns) - Overview.

Note

If you are filing multiple slips electronically for the same return type, tax year and account number, group all slips together under one summary and file as one return. File original and amended slips in separate returns. For more information on filing information returns using the Internet, go to Filing Information Returns Electronically (T4/T5 and other types of returns) - Overview.

On paper – 1 to 5 T4 slips

The CRA encourages you to file your T4 return electronically. However, if you have 5 slips or less, you can file on paper.

For a paper version of our forms and publications, go to Forms and publications or call 1-800-959-5525.

Fill out one copy of each T4 slip you need to fill out for each employee and include it with your T4 Summary when you file. Enter the information for two different employees on one sheet.

The T4 return is mailed to the address provided on the T4 Summary.

You must keep a copy of the T4 slips and summary for your records. For more information about how to keep adequate books and records, go to Keeping records.

The CRA accepts customized versions of the T4 slip. For information, go to Customized forms.

T4 Summary sent without T4 slips

A complete return must be filed including the slips. If a T4 Summary is sent without the T4 slips, the following apply:

Failure to file electronically

If you file more than 5 information returns for a calendar year, you must file the returns electronically. After filing the original return, slips can be amended, added, or deleted in paper, or electronic format. For more information, go to Choose the filing method to amend, add, replace, or cancel T4 slips.

If you do not file electronically when you are required to do so, the penalty the CRA assesses is based on the number of information returns filed in an incorrect format. Each slip is an information return.

The penalty is calculated per type of information return. For example, if you file 6 NR4 slips and 6 T4 slips on paper, the CRA would assess two penalties of $125, one per type of information return.

Failure to file information returns over the Internet
Number of information
returns (slips) by type
Penalty
 
                                                         6 to 50                                         $125
51 to 250 $250
251 to 500 $500
501 to 2,500 $1,500
2,501 or more $2,500

Step 4 – General guidelines for T4 slips and T4 summaries

When filling out T4 slips:

How to report foreign income in Canadian dollars

Report all T4 amounts in Canadian dollars as per the Income Tax Act (ITA) requirements.

Bank of Canada

In general, the foreign currency amount should be converted using the Bank of Canada exchange rate in effect on the day it arises. For more information, go to Exchange rates.

Other acceptable sources

The CRA will also generally accept a rate for that day from another source if it is:

Other sources for rates that the CRA generally accepts include Bloomberg L.P., Thomson Reuters Corporation, and OANDA Corporation.

For more information, including circumstances where an average rate may be used to convert foreign currency amounts, go to Income Tax Folio S5-F4-C1, Income Tax Reporting Currency.

Filling out T4 slips based on the employment situation

Step 5 gives you instructions for how to fill out the identification area for all situations.

Step 6a gives you instructions for how to fill out the boxes and other information on T4 slips in most situations.

Step 6b gives you instructions for how to fill out the boxes and other information on T4 slips in the following special situations:

Other information

The “Other information” area at the bottom of the T4 slip has boxes for you to enter codes and amounts that relate to:

The boxes are not pre‑numbered. Enter the codes and amounts that apply to the employee. For more information, go to Identification and pre-numbered boxes.

Example
Box – Case
Amount – Montant
 

40

 

2400

98

If more than six codes apply to the same employee (overflow T4 slips)

If you have more than six “Other information” codes to enter, use an additional T4 slip, but do not repeat the amount already included in box 14. Do not repeat all the data on the additional slip. Enter only:

Salary overpayments

If you make an overpayment of salary, wages, or other remuneration to an employee, how you correct this will often depend on the reason the employee was overpaid and the year in which the employee repaid the amount.

You may need to correct overpayments in the following situations:

Employee did not perform their duties

Report the overpayment on the employee’s T4 slip. For more information, go to When the employee did not perform their duties

Clerical, administrative, or system error

Election for repayment of net salary

If your business is actively operating and you did not issue a T4 slip with the salary overpayment amount removed, you may elect to have your employee repay the net amount of the salary overpayment.

You must make the election in prescribed manner within three years of the year the salary was overpaid. At the time of the election, the employee must have repaid, or arranged to repay, the net amount. Your employer’s share of Canada Pension Plan (CPP) contributions and employment insurance (EI) premiums is not refundable. For more information, go to Correct deduction errors.

To make the election, choose any following action:

Repayment of gross salary

If you do not elect to have your employee repay the net amount of the salary overpayment or do not meet the conditions noted above, the employee must repay you the gross amount of the salary overpayment.

Reporting salary overpayment

For more information about an employee who repays you:

Giving your employees their T4 slips

You must give employees their T4 slips by the last day of February following the calendar year to which the slips apply. If you do not, the CRA may charge you a penalty of $25 per day for each T4 slip that is not given to an employee. The minimum penalty is $100. The maximum penalty is $2,500.

Methods of giving T4 slips

You may give T4 slips using any of the following methods:

Email

You must receive written consent from employees before sending T4 slips by email. 

Employer's electronic portal

You have to make the T4 slips accessible to your employees on a secure portal and with a secure printer. If your employees requests the T4 slips on paper, you must give them paper T4 slips.

Paper

If you choose paper, you must provide your employees with two copies of the T4 slip in person or by mail.

For security purposes, the employer’s payroll account number in box 54 should not be printed on these copies.

Unable to give T4 slips

If T4 slips are returned as undeliverable, you should keep the copies with the employee’s file.

If an employee’s address is known to be incorrect, T4 slips must not be sent to that address. You should do the following:

For more information, go to Distribute the slips.

When an employee leaves

When an employee stops working for you, the CRA suggests you calculate the employee’s earnings for the year to date and give the employee a T4 slip. Include the information from that T4 slip in your T4 return when you file it (usually on or before the last day of February of the following year). You must also issue a Record of Employment (ROE). For more information on the methods of use and when to issue the ROE, go to Access Record of employment on the web.

ZZ Other
Enter ZZ if an employee worked in a country other than Canada or the United States, or if the employee worked in Canada beyond the limits of a province or territory (for example, on an offshore oil rig).
Employee reporting to your establishment

If your employee reports to your business establishment in person, the province or territory to enter in box 10 is the one where that establishment is located. There is no minimum amount of time the employee has to report to that place.

Employee not reporting to your establishment

If your employee does not have to report to your business establishment in person (for example, the employment contract says the employee works from a home office), the province or territory to enter in box 10 is the one where your employee’s salary and wages are paid. This will normally be the location of your payroll department or payroll records.

Box 12 – Social insurance number

Enter the employee’s social insurance number (SIN), as provided by the employee.

If you cannot get a SIN from your employee, you still have to file their T4 slip without the SIN, on or before its due date. For more information, go to Social insurance number (SIN).

If your employee had a SIN beginning with a nine (9) and later in the year received a permanent SIN, use the permanent SIN in box 12. Do not prepare two T4 slips. If you do not have the employee’s SIN, enter nine zeros.

Penalty for failure to get an employee’s SIN

If your employee does not give you their SIN within three days of starting to work, you must be able to show that you made a reasonable effort to get it. If you do not, you may have to pay a penalty of $100 for each SIN you did not try to get. 

Step 6a – Fill out the remaining information on T4 slips for employees in most situations

Before you enter amounts, go to Step 4 – General guidelines for T4 slips and T4 Summaries.

If the employee is in a special situation, go to Step 6b – Fill out the remaining information on T4 slips for workers in special situations.

Box 14 – Employment income

Report your employee’s total income before deductions, including:

Note

Director’s fees paid to non-resident directors for services rendered in Canada must also be reported in box 14. However, a non-resident director is not considered to be employed in Canada when they do not attend any meetings or performs any other functions in Canada. For more information, go to Directors' fees.

Other amounts to report in box 14

These amounts include:

Employment codes

Do not report an amount in box 14 if you are using employment code 11, 12, 13, or 17 in box 29.

Do not report an amount in box 14 if you, as the employer, are paying CPP on behalf of detached employees under employment code 16 and no other type of income is reported.

For more information, go to Box 29 – Employment code.

How to report retiring allowances

Do not include retiring allowances in box 14. Report the amount using the appropriate code in the “Other information” section.

For more information, go to:

Canadian Forces personnel and police officers

Certain Canadian Forces personnel and police officers can claim a deduction from net income for the amount of employment income earned in certain circumstances (including taxable allowances). See Code 43 – Canadian Armed Forces personnel and police deduction.

Emergency volunteers

If you are a government, municipality, or public authority and you hired emergency volunteers (such as firefighters, ambulance technicians, or search and rescue volunteers), do not include in box 14 the first $1,000.

Report the exempt amount (up to $1,000) in the “Other information” area of the T4 slip, using code 87.

However, if you paid the individual other than as a volunteer for the same or similar duties, include the total amount in box 14. For more information, go to Emergency services volunteers.

Employees with power saws or tree trimmers

If you are an employer in the forestry business, you may have employees who, according to their contracts, have to use their own power saws or tree trimmers at their own expense.

Report in “Box 14 – Employment income” the rental payments you made to employees for the use of their own power saws or tree trimmers.

Do not reduce the amount reported in box 14 by the cost or value of saws, trimmers, parts, gasoline, or any other materials the employee supplies.

Employee salary overpayments if your employee does not repay you

When an employee does not repay a salary overpayment, report the overpayment in box 14 and the corresponding deductions in the appropriate boxes.

Employee salary overpayments if your employee repays you

How to report and correct an overpayment of employment income depends on whether the overpayment was the result of:

If you let your employee repay an overpayment in instalments, you may have to calculate a taxable interest benefit. For more information, go to Loans – interest-free and low-interest.

Clerical, administrative, or system error

If you already filed your T4 slip for the year the salary overpayment was made, go to Employee salary overpayments.

If your business is actively operating and you did not issue a T4 slip with the salary overpayment amount removed, you may elect to have your employee repay the net amount of the salary overpayment.

You must make the election within three years of the year the salary was overpaid. At the time of the election, the employee must have repaid, or arranged to repay, the net amount.

To make the election, choose any following action:

To determine the net amount, start with the gross amount and subtract the income tax, CPP, and EI that you withheld on the salary overpayment.

If you withheld Quebec Pension Plan (QPP) contributions or provincial parental insurance plan (PPIP) premiums on the salary overpayment, go to Guide TP-1015.G-V, Guide for Employers: Source Deductions and Contributions, or visit Revenu Québec.

Repayment of net salary (election)

If your employee repays or arranges to repay the salary overpayment before you file their original T4 slip, do not report the overpayment or corresponding deductions (income tax, CPP, or EI) on the T4.

However, if the amount of an employee’s corrected earnings are at or above the maximum annual pensionable earnings, include on their T4 slip the CPP contributions you withheld on the overpayment.

Also, if an employee’s corrected earnings are at or above the maximum annual insurable earnings, include on their T4 slip the EI premiums you withheld on the overpayment.

Repayment of gross salary (no election)

The employee must repay the gross if the election was not made or they did not meet the conditions.

If the employee repays you or arranges to repay, prepare an amended T4 slip for your employee. Use the CPP contributions, EI premiums, and income tax deductions from the employee’s original T4 slip, but reduce the employment income in box 14 by the amount of the salary overpayment.

You may also have to amend the EI insurable earnings in box 24 and CPP/QPP pensionable earnings in box 26 to agree with the reduced employment income you will report in box 14.

When the employee did not perform their duties

The employee or former employee should repay the gross overpayment if all the following conditions are met:

The following are examples of an employee that was paid when they did not work or fulfill the terms of their contract and received payments they were not entitled to:

Include the salary overpayment and the deductions withheld on the overpayment on the employee’s T4 slip.

Whether your employee repays you in the same year or a different year, do not amend their T4 slip. Give your employee a letter confirming the tax year when the overpayment was included in their income, as well as the date, reason, and amount of repayment you received. With that letter, the employee will be able to claim a deduction on line 22900 of their income tax and benefit return in the year the amount was repaid.

Your share of the CPP contributions and EI premiums is not refundable.

Example

In September 2023, Peter became ill and could not work. You continue to pay his regular salary. In February 2024, he begins to receive payments from a wage‑loss replacement plan and repays you the amount of salary he received from September 2023 to February 2024. Do not make any adjustments to his 2023 T4 slip or to his current‑year pay records to reflect the amount of repayment. Instead, Peter can claim a deduction for the repayment on his 2024 income tax and benefit return by providing a copy of the letter you gave him confirming the date and the amount he repaid you and the year the amount was included in income.

Boxes 16 and 17 – Employee’s CPP/QPP contributions

Report the amount of CPP or QPP contributions you deducted from the employee’s pensionable earnings.

Do not report any amount in either box 16 or box 17 if your employee did not contribute to either plan.

Box 16 – Province of employment other than Quebec

Report their CPP contributions in box 16 if box 10 shows their province or territory of employment is other than Quebec.

If you report an amount in box 16, you have to report pensionable earnings in box 26.

Do not report these amounts in box 24:

More than one T4 slip for the same employee

When you give the same employee more than one T4 slip for the year, you should report the insurable earnings amount for each period of employment in box 24 of each T4 slip.

Example

An employee earned $32,000 working in Ontario from January 2023 to June 2023 and earned $32,000 working in Quebec for the remainder of the year with the same employer. In addition to any other boxes that need to be filled out, report the amount in boxes 14 and 24 as follows:

Box 26 – CPP/QPP pensionable earnings

You must report an amount in box 26.

Report the total amount of pensionable earnings paid to your employee using box 26. This is the amount you used to calculate your employee's CPP/QPP contributions that you reported using box 16 and box 17, up to the maximum pensionable earnings for the year ($66,600 for 2023), even if you did not withhold CPP/QPP contributions on all or any of those earnings. In many cases, boxes 14 and 26 will be the same amount.

Report “0” if there are no pensionable earnings and there is no amount in boxes 16 or 17.

For T4 slips filed for calendar year 2024 and after, report the total amount of pensionable earnings using box 26. This is the amount you used to calculate your employee's CPP/QPP contributions that you reported using box 16, box 16A, box 17 and box 17A, up to the maximum pensionable earnings and additional maximum pensionable earnings for the year.

Non‑cash taxable benefits (including security option benefits)

If you give pensionable non‑cash taxable benefits, report their value in box 26, even if the employee received no other remuneration. For example, if your employee is on an unpaid leave of absence and you continue to provide benefits during the leave period, report the benefit in box 26.

CPP

Do not report these amounts in box 26:

a)    Remuneration paid to the employee:

b)    Amounts paid to the employee for employment, benefits, or other payments described in Retiring allowances, where no CPP contributions had to be deducted

c)  Amounts for a clergy member’s residence from which you did not deduct CPP contributions (if the clergy member gets a tax deduction for the residence, CPP contributions are not required). For more information regarding the clergy deduction, see Clergy Residence in the Determine if a benefit is taxable.

Subtract any of the amounts noted above from the amount in box 14, and enter the difference in box 26. Do not change the amount in box 14.

QPP

Fill out box 26 if you deducted QPP from the employees’ earnings, regardless of their province or territory of residence.

More than one T4 slip for the same employee

When you give the same employee more than one T4 slip for the year, you should report the pensionable earnings amount for each period of employment in box 26 of each T4 slip.

Example

An employee earned $35,000 working in Ontario from January 2023 to June 2023 and earned $35,000 working in Quebec for the remainder of the year with the same employer. In addition to any other boxes that need to be filled out, report amounts in boxes 14 and 26 as follows:

  • Ontario T4 slip – box 14 = $35,000 and box 26 = $35,000
  • Quebec T4 slip – box 14 = $35,000 and box 26 = $31,600 (calculated as the maximum pensionable earnings for 2023 of $66,600 – $35,000 already reported on T4 slip with Ontario as province of employment = $31,600) on the Quebec T4 slip

For more information, go to Guide TP‑1015.G‑V, Guide for Employers: Source Deductions and Contributions, or Guide IN‑253‑V, Taxable Benefits, or visit Revenu Quebec.

Box 26 greater than box 14

The T4 slip will still be processed even though box 26 is more than box 14.

The following examples show how to fill out boxes 14 and 26 of the employee’s T4 slip when you provide a benefit or earnings to an employee that is only taxable in Quebec.

Example 1- Quebec taxable benefit, unpaid leave

Marion works for her employer in Quebec and is on an unpaid leave of absence. Her employer pays $750 in premiums to an employer‑paid private health benefit plan on her behalf. Since the benefit is not taxable outside of Quebec, it is not income. When preparing Marion’s Quebec T4 slip, her employer will leave box 14 blank. Since the premiums are QPP pensionable, her employer will report $750 in box 26, the QPP contributions withheld on the benefit in box 17, and fill out any other boxes on her T4 slip as applicable.

Example 2- Quebec taxable benefit, other earnings

During 2023, Julien received wages of $25,000 plus an $875 benefit that is only taxable in Quebec. When preparing Julien’s Quebec T4 slip, his employer will report $25,000 in box 14, $25,875 in box 26, and fill out any other boxes on his T4 slip as applicable.

Example 3-Benefit is taxable both federally and in Quebec

Stephane works for his employer in Quebec and did not receive any cash earnings. However, his employer gave him a non‑cash housing benefit valued at $1,100. When preparing Stephane’s Quebec T4 slip, his employer will report $1,100 in boxes 14 and 26, and fill out any other boxes on his T4 slip as applicable.

For more information, go to CPP/EI Explained.

PPIP (Provincial parental insurance plan)

Leave box 28 blank if you reported an amount in box 55 or 56. Enter an “X” or tick in the “PPIP” box only if you did not have to withhold PPIP premiums from the earnings for the entire period of employment in the province of Quebec.

However, if you make contributions to union pension funds, enter the union’s plan number instead (the union is required to give that number to you).

If an employee is a member of more than one plan, enter only the number of the plan under which the employee has the largest PA.

Box 52 – Pension adjustment

If you have a registered pension plan (RPP) or a deferred profit sharing plan (DPSP), report, in dollars only, the amount of your employee’s pension adjustment (PA) for the year.

If you have to fill out more than one T4 slip for the employee because they worked in more than one province or territory, report the PA proportionately on each T4 slip. If you cannot apportion the PA, report the total amount on one slip.

If your employee participates in one or more RPP or DPSP, calculate their PA using the total amount of all pension credits accumulated by the employee under all these plans for the year.

If your employee is on a leave of absence and is still accruing pensionable service or credits under the plan, you must report the PA on a T4 slip. This is true even if the employee has no employment income in the tax year. Administrators of multi‑employee plans (MEPs) should report the PA for the employee on leave on a T4A slip.

Do not report any amount in box 52 if the employee participated in your RPP or DPSP and one of the following applies:

Special rules concerning the PA

CPP and EI overdeductions

After a T4 has been filed, to resolve a CPP and EI overdeduction:

Send Form PD24 no later than:

The CRA will credit the excess CPP and EI to the employee when they file their income tax and benefit return.

CPP and EI underdeductions

After a T4 has been filed, if you discover that you under-deducted CPP and EI from your employee (or you received a notice of assessment), you are responsible for remitting both the employee's portion and your portion of the balance due.

You can recover your employee’s portion from later payments you make to the employee. The following conditions must be met:

If you should have made a deduction in a previous year and you recovered it through an additional deduction in the current year, do not report the recovered amounts on the current year’s T4 slip.

The recovered amount does not affect the current year-to-date CPP or EI.

Employee salary overpayments

After a T4 has been filed, if you discover that you made a salary overpayment because of a clerical, administrative, or system error, amend the T4 slip for the year of the overpayment.

Employee repaying the net amount

If your business is actively operating and you included the salary overpayment amount on the original T4 slip, you may elect to have your employee repay the net amount of the salary overpayment.

You must make the election within three years of the year the salary was overpaid. At the time of the election, the employee must have repaid, or arranged to repay, the net amount.

To make the election, amend the T4 slip to:

After the CRA processes the amended T4, your payroll account will be credited an amount for the income tax, CPP contributions, and EI premiums remitted on the salary overpayment made in error (including your share of CPP contributions and EI premiums). The correct amount will be shown on your statement of account. You can then use the credited amount to reduce your next payroll remittance to the CRA.

Example 1 – Annual pensionable and insurable earnings are below the maximum

In 2023, your employee earned $36,000. In 2024, after you filed their original 2023 T4 slip, you discovered you overpaid them by $1,000 because of a system error. From the overpayment, you had deducted income tax of $100, CPP contributions of $59.50, and EI premiums of $16.30.

In 2024, your employee agreed to repay you the net amount of the salary overpayment. You should amend their 2023 T4 slip to reduce each of the following amounts by $1,000:

  • total employment income in box 14
  • EI insurable earnings in box 24
  • CPP pensionable earnings in box 26

You should also reduce:

  • the amount of income taxes deducted in box 22 by $100
  • the CPP contributions in box 16 by $59.50
  • the EI premiums in box 18 by $16.30

You can reduce your next payroll remittance to the CRA by the following amounts:

  • $100 of income tax deducted on the salary overpayment
  • $59.50 of CPP contributions deducted on the salary overpayment
  • $16.30 of EI premiums deducted on the salary overpayment
  • your $59.50 share of CPP contributions
  • your $22.82 share of EI premiums

Example 2 – Annual pensionable and insurable earnings are above the maximum

In 2023, your employee earned $70,000. In 2024, after you filed their original 2023 T4 slip, you discovered you overpaid them by $20,000, because of a system error.

In 2024, your employee agreed to repay the net amount of the salary overpayment. You should amend their 2023 T4 slip to reduce:

  • total employment income in box 14 by $20,000
  • CPP contributions in box 16 by $987.70 (the $16,600 difference between the maximum pensionable earnings and the corrected earnings multiplied by the 5.95% employee CPP contribution rate)
  • EI premiums in box 18 by $187.45 (the $11,500 difference between the maximum insurable earnings and the corrected earnings multiplied by the 1.63% employee EI premium rate)
  • income taxes deducted in box 22 by $2,200 (the amount deducted on the salary overpayment of $20,000)
  • EI insurable earnings in box 24 by $11,500 (maximum insurable earnings of $61,500 minus corrected earnings of $50,000)
  • CPP pensionable earnings in box 26 by $16,600 (maximum pensionable earnings of $66,600 minus corrected earnings of $50,000)

You can reduce your next payroll remittance to the CRA by the following amounts:

  • $2,200 of income tax deducted on the salary overpayment
  • $987.70 of CPP contributions deducted on the salary overpayment
  • $187.45 of EI premiums deducted on the salary overpayment
  • your $987.70 share of CPP contributions
  • your $262.43 share of EI premiums

Employee repaying the gross amount

Employees should repay the gross amount of a salary overpayment if either of the following apply:

In this situation, the employer must prepare an amended T4 slip for the employee. Use the CPP, EI, and income tax deduction amounts from the employee’s original T4 slip, but reduce the employment income in Box 14 by the amount of their salary repayment. If necessary, amend the insurable earnings in Box 24 and pensionable earnings in Box 26 to agree with the reduced employment income that will be reported in Box 14.

To recover the employer portion of any CPP or EI overcontribution, fill out Form PD24, Application for a Refund of Overdeducted CPP Contributions or EI Premiums, and send it no later than:

For further instructions on which boxes may need to be amended, including examples how to adjust EI/CPP contributions and deductions when annual insurable/pensionable earnings are below or above the maximum, go to Correct deduction errors.

Example

In 2023, your employee earned $36,000. In 2024, after you filed the original T4 slip, you discover you overpaid them by $500 because of a calculation error. You do not elect to have them repay the net amount, and they agree to repay you the gross amount in 2024.

You should amend their 2023 T4 slip to reduce the total employment income in box 14, as well as the CPP pensionable and EI insurable earnings in boxes 26 and 24 by $500. Do not adjust the amount of CPP contributions, EI premiums, or income tax deducted in boxes 16, 18, and 22.

Changes to the pension adjustment

If you have to recalculate the pension adjustment (PA) for an employee, you have to report an amended PA for each year after 1989 that is affected.

You do not have to report an amended PA if the difference is less than $250, unless an employee or the CRA asks you to report the amended PA.

For the years in which you did not previously report a PA for the employee, you have to file an amended T4 slip showing the correct PA. If you previously reported a PA for the employee in a particular year, you have to show the total PA that applies for that year on an amended T4 slip.

For information on recalculating a PA, go to Pension Adjustment (PA). For information on calculating and reporting PSPAs, go to Guide T4104, Past Service Pension Adjustment Guide.
