Tax Slip FAQs

This is last year's information, but your 2021 tax slips will follow a similar process. Check back in January for more info!

1. How do I modify employee tax slips? 

You can update your employee’s tax slips in Modify Employee Tax Slip Data. For more information, go to Review, Modify, and Add Employee Tax Slips.

Before updating your employee’s tax slips, please ensure that you've finished extracting the tax slip data. If you extract after making changes to the employee’s tax slip data, your changes will be lost, and you’ll need to make those updates again.

2. What are boxes 57-60 on my employee’s T4s? 

This year, there are four additional boxes on your T4 slips to report employee earnings and taxable benefits during the federal response to COVID. All employers must populate boxes 57-60, regardless of whether your organization participated in any federal COVID relief program. Go to T4 Changes for Federal COVID-19 Response for more information.

3. What are the Review Listings? 

It's important to check your Review Listings to ensure your tax slip information for 2020 is accurate. These include a summary of the vital tax slip information for each group. You can also include the tax slip information for each employee in the group.

The Review Listings will include the tax slip boxes with an amount. Additionally, it displays any CPP, QPP, EI, and QPIP discrepancies of more than a dollar. Go to Print The Tax Slip Review Listings for more information.

4. How do I submit the transmission file to the CRA or MRQ? 

Once you’ve generated your transmission files, log into the CRA or MRQ website and follow the onscreen instructions to upload the files. The site will verify when the file is uploaded successfully. Make sure you have your web access codes and credentials on hand.

5. When should I amend vs cancel a tax slip? 

If you find an error in your tax slips after you’ve submitted them to the CRA or MRQ, you’ll need to create amended or cancelled tax slips. Typically, you’ll need to create an amended file, unless the CRA or MRQ recommends a cancelled file.

To create amended slips, go to Amending Tax SlipsTo cancel your tax slips, go to Cancelled T4/T4A or Cancelled RL1/RL2 for more information.

6. How can I deliver tax slips to terminated employees?
