Answering this question
This section will help you work out how much you can claim. You can use the Invalid and invalid carer tax offset calculator to answer this question. Write your offset amount at B item T6 on page 16 of your tax return.
You can only claim one tax offset for each person satisfying steps 1 to 5 above.
If the person you maintained was an invalid and a carer of an invalid during the income year, claim for the total time that the person was either an invalid or a carer of an invalid.
If you maintain more than one spouse at the same time, you can only claim the spouse you live with. If you do not live with any of your spouses or if you live with more than one spouse you can only claim for the spouse with the lowest tax offset.
Your claim will be reduced for any period that you or your spouse were:
- eligible for family tax benefit (FTB) Part B, or
- receiving parental leave pay.
Your claim will also be reduced for any period during the year that the person you maintained:
- was under 16 years old
- was not maintained by you
- was not an Australian resident, or
- did not receive the relevant pension, allowance or payment.
You can use the Invalid and invalid carer tax offset calculator to answer this question. Write your invalid and invalid carer tax offset at B item T6 on page 16 of your tax return.
Alternatively, for each invalid and invalid carer you have maintained:
- follow the steps in the worksheet table under Completing your tax return
- add together the offset you work out for each person you have maintained to get your maximum entitlement
- write your invalid and invalid carer tax offset total at B item T6 on page 16 of your tax return.
