Investment Income, Dividends and Rentals: How They Affect CCS and FTB
Your taxable income and your Adjusted Taxable Income (ATI) for Centrelink purposes are not the same thing. Several income types that reduce your tax return — like investment losses — are added back when calculating CCS and FTB eligibility.
What is ATI and why does it differ from taxable income?
As explained in our guide on Adjusted Taxable Income (ATI), ATI is the figure Services Australia uses to test your eligibility for payments. While taxable income is what you pay tax on after deductions, ATI is designed to reflect your "actual" financial capacity by adding back certain tax-reducing items.
Investment income add-backs (the ones that catch families out)
Many families are surprised at balancing time because they didn't realize certain "losses" or "benefits" are treated as income for CCS and FTB purposes.
1. Rental property losses (Negative Gearing)
If you own a rental property and your expenses (interest, maintenance, depreciation) exceed the rent you receive, you claim a "net rental property loss" on your tax return. While this reduces your tax, the entire loss is added back to your ATI.
Example: If you claim a $15,000 rental loss, your CCS income appears $15,000 higher than your taxable income.
2. Total net investment losses
The same principle applies to financial investments like shares or managed funds. If your investment deductions exceed your investment income, the net loss is added back to your ATI.
3. Reportable fringe benefits
Salary-packaged amounts are a common trap. Even if a benefit is tax-exempt, like an EV novated lease, it often generates a Reportable Fringe Benefits Amount (RFBA). This amount is "grossed up" and added to your ATI. A $15,000 benefit can add nearly $28,000 to your ATI.
4. Reportable employer super contributions
Voluntary superannuation contributions (salary sacrifice) or personal contributions for which you claim a tax deduction are added back to your ATI. Compulsory employer contributions (the 12% Super Guarantee) are not included.
What is NOT added back?
Bank interest and dividends (whether franked or unfranked) are already counted as part of your taxable income. They don't require a separate "add-back" because they haven't been subtracted; however, they still increase your total ATI because they increase your taxable income.
A concrete example: The "Negative Gearing" Trap
Consider a couple with the following:
- Combined Salary: $120,000
- Rental property loss: -$18,000
- Taxable Income: $102,000
On their tax return, they only pay tax on $102,000. However, for CCS purposes:
- ATI: $120,000 ($102,000 + $18,000 loss added back)
For the 2025-26 financial year, an income of $102,000 would place the family in a higher subsidy bracket. But because their ATI is $120,000 (which is above certain thresholds), their CCS rate will be lower. This gap can easily result in a $3,000 to $5,000 difference in annual subsidy.
Why families don't notice until balancing
During the year, many families estimate their income based on what they think they "earn" or what they expect to see on their tax return. Centrelink pays the subsidy based on this estimate.
At the end of the year (balancing), the ATO sends your actual ATI to Services Australia. If you didn't account for rental losses or fringe benefits in your estimate, your actual ATI will be much higher than your estimate, triggering an automatic CCS debt.
How to get your ATI estimate right
To avoid a surprise debt, follow these steps when updating your estimate in myGov:
- Start with expected taxable income: Use your last tax return as a baseline.
- Add back rental/investment losses: Look at any negative gearing or investment losses you plan to claim.
- Add RFBA: Check your latest income statement or ask your employer for your expected Reportable Fringe Benefits Amount.
- Add voluntary super: Include any salary sacrifice amounts.
Use this total figure when running an estimate in our CCS Calculator.
Key Takeaways
- Taxable income ≠ ATI: Losses that reduce your tax are added back for Centrelink.
- Negative gearing hurts CCS: Rental losses increase your ATI dollar-for-dollar.
- Fringe benefits are "Grossed Up": The impact of salary packaging on ATI is often nearly double the actual benefit value.
- Check before balancing: If you have investments, always over-estimate your income slightly to create a safety buffer.
FAQ
If I have a positively geared property, does that add to ATI?
Yes, but it's already included in your taxable income. Since it's a profit, not a loss, there is no "add-back" needed—the profit itself just makes your taxable income higher.
Does salary sacrifice for a car affect ATI?
Yes. Most car leases result in a Reportable Fringe Benefit Amount (RFBA) appearing on your payment summary, which is added back to your ATI.
How do I find my RFBA amount?
It is usually listed on your final end-of-year income statement (formerly group certificate) in myGov. Your payroll department can also provide an estimate during the year.
