Helpful Information

Every tax year, employers in Canada who have paid out remunerations to employees throughout the year are required to fill out and issue T4 slips to their employees.

If you're new to payroll or the year-end process, here's some background on T4s and the requirements that go with them. Most amounts paid by an employer to an individual are referred to as "remuneration," and T4 slips cover the following types of remuneration:

  • Salary, wages (including pay in lieu of termination notice), tips or gratuities, bonuses, vacation pay, employment commissions, gross and insurable earnings of self-employed fishers, and all other remuneration (see Box 14 – Employment income, for a detailed list) you paid to employees during the year
  • Taxable benefits or allowances
  • Retiring allowances
  • Deductions you withheld during the year
  • Pension adjustment (PA) amounts for employees who accrued a benefit for the year under your registered pension plan (RPP) or deferred profit-sharing plan (DPSP)

All remuneration types that are included in Humi by default are automatically assigned to the corresponding boxes on the T4 slip. If you’ve requested a custom Income Type, you would have been asked to select the T4 box to which the remuneration needs to be assigned.


Benefits are reported in all required boxes on T4 slips

Taxable allowances and benefits may have additional T4 reporting requirements.

For example, in addition to reporting a housing allowance in Box 14 as employment income, it must be reported again in the T4 slip's "Other Information" section with code 30.

All benefits and deduction types that are included in Humi by default are automatically assigned to the corresponding boxes on the T4 slip. If you’ve requested a custom Benefit or Deduction, you would have been asked to select the T4 box to which the benefit needs to be assigned.

For more information about benefits reporting, see Step 2: Review Taxable Benefits


Verify YTD records are accurate

Employers who changed payroll providers and started using Humi Payroll mid-year were required to upload Year-To-Date (YTD) payroll records.

When T4 slips are prepared, the YTD amounts are added to the amounts processed through Humi Payroll to provide a full year's context on Payroll.

It's important to review and update the records if necessary to ensure they accurately represent payrolls processed through previous payroll providers.

Now that you've read those helpful tips, let's dive into this article where we'll explain the following steps to create and file your T4s:

  1. Run your T4s in Humi
  2. Review T4’s
  3. Finalize T4s in Humi
  4. Download the Tax Package from Humi
  5. Send T4s to employees


Part 1 - Run your T4s in Humi

We've made it simple to run your T4s in Humi. If you're unsure how to do this, check out this detailed article: How to generate employee T4s.


Part 2 - Review T4’s

In step 1, Humi totalled all the information in our system to create the T4s. This is your opportunity to look at those T4s and ensure everything is correct prior to submission.

Two boxes on the T4 must be filled in by a payroll administrator because the data is not based on payroll history during the year:

  • Box 45 Employer-offered dental benefits
  • Box 50 RPP or DPSP registration number

Humi’s made it easy to enter this information in the Year End Adjustment flow. If you skipped that step or missed an employee, Humi will show you a warning if you are missing this information on the T4, so you can enter it directly by Editing the T4.


Part 3 - Finalize T4s in Humi

By clicking Finalize and Submit you're telling Humi that you've verified all T4s are correct, and the T4s are now locked. By default, Humi files your T4s with the CRA.

If you would like to opt out of the filing service, you can select "I do not want Humi to submit to the CRA on my behalf" prior to Submitting the T4s.

  1. If Humi is filing your T4s, then proceed to Step 4 Download Tax Package.
  2. If you’ve opted out of Humi’s T4 filing service, then proceed to Part 3 (b) - File slips and summaries with the CRA


Part 3 (b) - File slips and summaries with the CRA

What's a T619?

The T619 is an electronic transmittal record of T4 and T4 Summary. This is to be downloaded and filed with CRA. In addition, the T619 can also be downloaded and viewed as a text file.

If you’ve opted out of Humi’s T4 filing service, then after you've finalized your T4s you'll need to download and upload the T619 file onto the CRA's online portal, Internet File Transfer Option.


How to File Online with the CRA

You can also file the T619 by logging into My Business Account and filing it from there.

The link to do so is also available in the banner just above the list of employee T4s in-app: Payroll > Records > Tax Forms > click into the Employer Package

Part 4 - Download the tax package from Humi

The Humi Payroll Tax Package provides two types of tax information for review and filing needs:

Employee T4‍s
T4 slips are summaries of employment earnings and annual deductions for individual employees. Humi will produce T4s for active and terminated employees, as long as the employees have been paid through Humi Payroll in the past.

The T4Summary shows the total of the information reported on all of the T4 slips you prepared for each employee for the calendar year.

You can find the T4 summary in the T4 module located below each Employee's T4s. It's important to note that our T4 summary is view-only and can't be downloaded. That's because the CRA doesn't require a T4 summary if your T4s are filed electronically.

If you do need a T4 summary, no worries! Just visit this link to grab a fillable T4 Summary in PDF format. Easy peasy!

Learn more from the CRA


Part 5 - Send T4s to employees

Once you’ve finalized the T4s, you can click "Send T4s to employees" to send the password-protected T4 email to all employees who require a T4.

On the "Tax package" page in Humi, click "Send T4s to employees" to send a secure PDF T4 file to each employee's email address which is based on the contact information saved in Humi.


Humi Tip

To ensure the email address in Humi, you can ask them to verify the email on their employee profile and update it if necessary.
