Before you use this calculator

The calculator results are based on the information you provide at the time of calculation. You should use the results as an estimate and for guidance purposes only.

If you only maintain an invalid spouse or care for an invalid for part of the income year, you can't clam the full tax offset. Use the calculator to work out the invalid or invalid carer offset for each period and add the results.

Claiming the invalid or invalid carer offset

The offset for maintaining an invalid or invalid carer is only available in limited circumstances.

You can't claim this offset for maintaining an invalid or invalid carer who received their government invalid or carer payment for the full income year. This is because these payments reduce your offset to $0.

You can claim for your spouse only as an invalid or an invalid carer, not both.

You can't claim the offset if your adjusted taxable income (ATI) is more than the amounts in the table below.

For eligibility criteria and more information, see Offset for maintaining an invalid or invalid carer.

To calculate the offset you'll need to have the following details:
