The Basics of Child Support in New Zealand

In New Zealand, child support is governed by the Child Support Act 1991. This legislation establishes a framework for assessing, collecting, and distributing child support payments. The primary purpose of child support is to ensure that both parents contribute financially to their child’s upbringing, even if they are no longer in a relationship.

The Inland Revenue Department (IRD) is responsible for administering the child support system. They use a formula to calculate the amount of child support a paying parent must provide, taking into account factors such as both parents’ income, the number of children, and the amount of care each parent provides.

Determining Income for Child Support Purposes

When assessing child support, the IRD considers the taxable income of both parents. This includes income from various sources, such as:

  • Wages and salaries
  • Self-employment income
  • Interest and dividends
  • Rental income
  • Bonuses and overtime pay

The IRD typically uses the income information from the most recent tax year to calculate child support obligations. However, if a parent’s income has changed significantly since their last tax return, they can request an administrative review to have their child support assessment updated.

How Bonuses and Overtime Affect Child Support Calculations

Bonuses and overtime pay are considered part of a parent’s taxable income and are therefore included when calculating child support. This means that if a paying parent receives a bonus or works overtime, their child support obligation may increase accordingly.

The Child Support Act 1991, Section 29, defines “income” for child support purposes as:

“…the taxable income of the person in the most recent tax year for which the person has filed a tax return with the Commissioner of Inland Revenue, unless the context otherwise requires.”

This broad definition of income ensures that all relevant sources of income, including bonuses and overtime, are taken into account when determining child support obligations.

Adjusting Child Support for Changes in Income

If a paying parent experiences a significant change in their income due to bonuses or overtime, they may request an administrative review of their child support assessment. The IRD can then adjust the child support payments to reflect the parent’s current financial situation.

It’s important to note that both increases and decreases in income can trigger a review. If a paying parent’s income decreases substantially, they may be eligible for a reduction in their child support obligations. Conversely, if their income increases significantly due to bonuses or overtime, the receiving parent can request a review to ensure that the child support payments are adjusted accordingly.
