Other Employer Reports & Processes

This page provides process information on the Bi-weekly I3 Deemed Contributions Report, Monthly New Buyback Report, and Annual I7 Pension Adjustment Report and Amended PAs.

Go to Summary of Employer Reports for a list of all employer reports.

Bi-weekly Deemed Contributions Report (I3)

The I3 deemed contributions report contains “deemed” contributions for each plan per member on Long Term Disability (LTD) during the pay period being reported. Deemed contributions are contributions that participating employers contribute on behalf of members on LTD or, for WSIB only, Short Term Disability (STD) on and after Day 41.

The I3 deemed contribution report is sent by WTW to each participating employer bi-weekly via DataLink and includes:

    • Accrual in deemed contributions for each pay period based on a year-to-date calculation, where
    • Amounts can reflect retroactive deemed contributions with respect to a current or prior calendar year (i.e., it is possible that a negative amount will be passed following a data change (e.g., return to work date received late), and
        • Applies to the following statuses:
          • STD – Day 41 (for WSIB only)
          • LTD – Paid-Accruing
          • LTD Accruing – Accruing – Partial Return

Refer to Contribution Remittance for details on how you remit the deemed employee and/or employer contributions to the pension plan fund.

Monthly New Buyback Report

The Buyback Report contains buyback information for each plan per member who completed a purchase (or “buyback”) of eligible pensionable service during the reporting period. The Buyback Report is sent by WTW to each participating employer monthly via DataLink and includes:

    • Employee and Employer buyback contributions amount by plan
    • Contribution amount for Box 20 of the T4 for a member who purchased service during the tax reporting year

You must add/update the amount in the Box 20 column to Box 20 (Registered Pension Plan (RPP) contributions) of the T4 tax slip for the applicable reporting year.

Refer to Contribution Remittance for details on how you remit the employer contribution portion to the pension plan fund.


Update Box 20 of the member’s T4 tax slip on your payroll system with the information provided in the Buyback Report.

Annual Pension Adjustment Report (I7)

A Pension Adjustment (PA) reflects the value of the pension benefit the member accrues in the Plan for a year. An employer must report all current service PAs by the end of February in the year following the benefit accrual.

On an annual basis you will receive the PA amounts for members which you need to report on the employee’s T4 tax slip. In mid-January, an I7 PA report will be provided to each employer via DataLink. Each employer is responsible for importing the PA amount into their pay system. The report will contain the following information:

  • Year
  • Member’s SIN
  • Member’s First Name
  • Member’s Last Name
  • Member’s PA
  • SWA ID Number (SWA members only)

Amended PAs

A member’s PA will need to be amended whenever the member’s entitlement to a benefit is changed for a prior tax-reporting year. There are special events that could give rise to the amendment of a member’s PA:

  • A purchase (or “buyback”) of pensionable service made before April 30th for a period of absence that happened in the same tax year
  • Grievance settlement or reinstatement
  • LTD settlement
  • Incorrect/inaccurately calculated PA

Note: Any prior year retroactive earnings will be included in the PA for the year in which it is paid (an amended PA is not required).

On an annual basis, you may receive an amended PA amount/report for members where the amount will need to be reported on amended T4 tax slip. In mid-April, as per the Annual Consolidated Processing Calendar, if required, a I7 PA report with the amended PA amount will be provided to each employer via DataLink. Each employer is responsible for importing the file, or entering the amounts, into their payroll system and issuing the amended T4 tax slip to the members.
