A record of the changes can be found on the Change Log tab, which you can print.

Make a note of the day and time you start making these adjustments. This will come in handy when you recreate employee tax slips and files to submit to the CRA or RQ.

Step 7: Repeat Steps 4 to 6 for each employee you need to create an amended tax slip for in the tax slip group.

Step 8: Once you are finished making changes in this tax slip group, select Print Change Log. From here, you can save a copy of the changes for your records and the audit trail.

Step 9: Repeat Steps 3 to 8 for each tax slip group that needs an amended tax slip.

How to Validate the Tax Slip

Validate the tax slip groups with updated tax slips before creating your employees’ amended tax slips or the CRA or RQ transmission file.

If you need additional details on validating, go to Validate Your Tax Slips.

Step 1: Open Validate Tax Slip Data in the Avanti Desktop Application.
By default, this can be found in Canadian Payroll >> Tax Slip Processing.

Step 3: Select the Tax Slip Groups with amended tax slips.

Step 4: Select OK to start the validation. The Results will display any errors and warnings identified.

  • Errors that appear in red must be fixed before creating and saving the transmission file. If your file has errors, please make adjustments.

  • Warnings that appear in blue should be addressed, but they’re not required.

Additional Information
If you’re creating tax slips for a Corporation rather than a Sole Proprietorship or Partnership, you’ll see an Employer SIN missing for tax slip group 
warning. Please ignore this warning.

Great! You’re done validating the tax slips.

How to Generate the Tax Slip File

Step 1: In the Avanti Desktop Application, open the program for the tax slip file you amended.

  • Generate T4 XML Data

  • Generate T4A XML Data

  • Generate RL-1 XML Data

  • Generate RL-2 XML Data

By default, these can be found in Canadian Payroll >> Tax Slip Processing >> Generate Transmission Media.

Step 2: Select 2023 for Tax Year.

Step 3: In Data Type, select:

  • Replacement Data if you’re generating the file for the CRA.

  • Amended file if you’re generating the file for RQ.

Step 4: Select which tax slip data you’d like included in the file:

  • Modified on or After: Select to include all employees with tax slip data changed after the date and time you specify.

Step 5: Update the Data file name so you don’t overwrite the original file.

 for more details.

Step 8: If there are no errors, your transmitter file is created in Avanti. Determine whether you’d like to save a copy of the file to your network.

  • To save the file to your network, select Yes.

  • To save a file at a later time, select No. Congratulations! You’re all done creating your transmitter file.

Additional Information
If you’re not submitting the file to CRA or RQ immediately, we recommend selecting No and saving the file once you’re ready to submit. This will prevent accidental changes to the file.

Go to Create Tax Slip Transmission Files for CRA or RQ for details on creating the file at a later time.

Step 9: Navigate to a secure location, then select Save.

Step 10: Determine whether you’d like to update the transmitter date.

  • Select Yes to update the transmitter date with the current date and time.

  • Select No to leave the transmitter date blank.

Additional Information 
Setting the transmitter date will help prevent users from accidentally overwriting the transmitter file in Avanti. You’ll need to remove the transmitter date before Avanti will create a new transmitter file.

Congratulations! You’ve created your transmission files. You can transmit these to the CRA once you’ve confirmed your tax slips are correct.
