You can estimate your income for child support when you expect it to be at least 15% less than the income used to work out your current child support assessment.
Before you start
- your total income for the year so far, since 1 April and including any overseas income
- what you think your income will be for the rest of the year.
In myIR, select 'More...' from the child support account panel
Select 'Apply for a child support income estimation'

What happens next
If we accept your estimate, we'll reassess your child support and send you a new notice.
After the end of the tax year, we'll compare the income you estimated with what you actually earned. If necessary, we'll reassess your child support.
If we cannot accept your estimate, we'll send you a letter explaining why.
We may ask you for evidence to support your estimate. These could be payslips or a letter from your accountant or tax agent, for example.
If your estimate includes overseas income, you'll need to send us proof of the actual income you earned after the end of the New Zealand financial year (1 April to 31 March).
