Changing your income estimate

Changing your income estimate for child support assessments

If you choose to estimate your income for the child support assessment, you can change your estimation during the year, or even cancel it, if your income changes.

• To make a new estimate, fill in another Estimate of income for child support assessment 2005 (IR104) form. You must show that your income has fallen by at least 15% from your original taxable income.
• To cancel your estimation, use the online cancellation of income estimation for child support form or download a Cancellation of income estimation for child support (IR111) form to complete and post back to us.

Both forms are also available by calling INFOexpress.

If your income does change or you have made a mistake in your estimate, please contact us immediately on freephone 0800 221 221. You may face a penalty for seriously underestimating your income.
