Earnings Apportionment Tool (EAT) 107-03020010



This document outlines how to use the Earnings Apportionment Tool (EAT). EAT has not been updated post Changing the Social Security Income Assessment Model (CAM) that applies from 7 December 2020. EAT still apportions the employment income to a customer's entitlement period.

Scope and function

EAT is a spreadsheet that:

  • accepts actual verified employment income
  • apportions the employment income to a customer's entitlement period
  • transfers the actual and apportioned employment income to the customer's Centrelink record

EAT as a support tool

EAT does not calculate debts, but helps record one-off employment income. Use EAT to:

  • download actual employment income from the customer's record, and
  • the Debt Explanation tool (ADEX) to explain how the employment income was assessed

There are limits on which debts can be calculated on the Centrelink system. See the ADEX training module.

Business integrity requirements

Upload the EAT sheet for combined debts raised for more than $10,000.

If using online workflows, there will not be an EAT sheet to upload. For prosecution referrals, the sheet in its original form is required. These can be uploaded using the Document Upload Facility when saved as an XLSX file type.

The Resources page has links to the EAT tool, user guide and Digital Image Deletion Request form, common errors, and FAQs.
