When to use this guide
You can estimate your income if you expect to earn at least 15% less than the income we've used to work out your child support (or your taxable income if we've used the maximum income amount).
What you will need
You can either write a letter or complete our Estimate of income for child support assessment (IR104) form.
We need to receive this before the end of the child support year it applies for.
Please include:
- your estimate of how much you expect to earn for the whole child support year (1 April to 31 March)
- evidence to support your estimation - for example, payslips or, if you're self-employed, a letter from your accountant.
