Generate T4 and T4A

Updated March 18, 2026 19:27

The Avionté application tracks and organizes employee data used to generate T4 and T4A reports for submission to the Canada Revenue Agency (CRA).

Setup

Before generating data and reports, Supplier Property values such as registration numbers or contact names can be edited in two ways: Avionté Admin Tools or the Generate T4/T4A window itself. Both areas communicate with each other, so a change in one location is saved to the other.

Setup - Admin Tools

The values in the T4/T4A Generator are auto-populated based on Supplier Properties in Admin Tools. These values are typically set when a supplier is created but can be edited at any time by a user with Admin rights.

Navigate to Start Page > Actions Menu > Admin Tools > Category = Employer > Employer > Detail tab.
Enter "T4" into the Property column's filter cell. This narrows the list to only Supplier Properties with "T4" in the title.
Mouse-over a cell in the Value column to reveal an Edit button.
Click Edit. A Value editor displays.
Click on the text to edit.
Click OK to save the change.
The edit appears in the Value column. Click Save to save the Supplier Property.
A confirmation window displays. Click OK.

The updated value is also saved to the corresponding field in the Generate T4/T4A window.

T619, Electronic Transmittal

The first element in the XML file will always be the T619 if the T4 Transmitter Account Number is entered.

- rpt_tcd
- trnmtr_nbr

- trnmtd_addr/ (including addr_l1_txt, addr_l2_txt, cty_nm, prov_cd, and pstl_cd)
Fields Updated — These fields have been renamed for clarity:
- TransmitterName/l1_nm (previously trnmtr_nm/l1_nm)
- TransmitterCountryCode (previously trnmtd_addr/cntry_cd)
New Field Added: T4 Transmitter Account Number
Based on a new Supplier Property: "T4 Transmitter Account Number". This field appears in the XML if it matches one of the following formats:
- bn15 — 15 alphanumeric characters
- bn9 — 9 numeric characters
- trust — 1 alpha + 8 numeric characters
- nr4 — 3 alpha + 6 numeric characters
New Field Added: T4 Transmitter Rep. ID
Based on a new Supplier Property: "T4 Transmitter Rep. ID". This field appears in the XML if it matches the following format:
- TransmitterRepID — 7 alphanumeric characters (Representative Identifier). Required if logged in using the Represent a Client (RAC) application.

Note: If a Transmitter Account Number value does not match one of the accepted formats, an error will be triggered.

The Generate T4/T4A window displays. Click into any field to edit the properties.
