You need to repay donation tax credits to us if a donee organisation returns your donation to you or an associated person.
You only need to return donation tax credits if your donation was returned on or after 26 August 2025.
If you did not claim and receive donation tax credits for your returned donation, you do not need to do anything.
Returning your donation tax credits
The easiest way to do this is in myIR.
Go to your donation tax credit account. Select ‘More’, then ‘Send a web message’.
In your web message, tell us the:
- name of the donee organisation that returned the donation
- date of the original donation receipt
- donation amount that was returned to you or an associated person
- date the donation was returned.
Other ways to do this
If you do not have myIR, you can give us the information by calling our general enquiries number.
What happens next
We will contact you if we need more information.
