How to claim your tax credit

Keep it, or pass it on. But don't leave it.

I don't want to claim my rebate.

You didn’t donate to get a rebate - we get that. New Zealanders are generous with time and money by nature.

If it remains unclaimed after 4 years, though, it's gone.

Close to $250 million goes unclaimed in New Zealand every year, meaning IRD may have an estimated $1 Billion waiting to be claimed – is some of it yours?

If yes, this means your rebate will sit making no difference at all.

Rather than letting it sit unused, you can claim your rebate through your myIR account and choose to donate it back to ChildFund New Zealand at the end of the process.

You can also amend previous returns (generally up to four years) to add missed donations - do this by logging in, reviewing your returns, and adding forgotten expenses, income, or donations.

Remember, you can request past receipts from ChildFund New Zealand at any time.
