Centrelink Adjusted Taxable Income Calculator
Build family assistance ATI from taxable income and add-backs, then check whether your current income estimate may be too low or high.
01 —FAMILY INCOME COMPONENTS
Enter combined amounts for you and your partner where Services Australia assesses family income.
This may differ from the RFBA on an income statement for some employer types. Check RFBA impacts.
02 —ATI AND ESTIMATE GAP
Awaiting input
Enter combined taxable income and the current family income estimate.
What this estimate includes
- The result separates ATI additions from deductible child maintenance.
- The estimate comparison flags a gap of at least $100.
- Family ATI may need both partners’ amounts; this calculator models the entered person or combined inputs only.
Frequently asked questions
Is adjusted taxable income the same as taxable income?
No. Family assistance ATI starts with taxable income, adds specified amounts such as reportable super contributions and net investment losses, then subtracts deductible child maintenance expenditure.
Why should I compare ATI with my current family income estimate?
Services Australia balances payments using actual income. A materially low estimate can contribute to an overpayment, while a high estimate may reduce fortnightly payments and later produce a top-up.
Should I enter the RFBA from my income statement as adjusted fringe benefits?
Not automatically. Family assistance rules can adjust reportable fringe benefits differently depending on the employer. Confirm the applicable amount before entering it.
