What Is an Expense in New Zealand Accounting? Definition, Types & Tax Rules

Expense

Costs incurred in operating a New Zealand business, such as wages, rent, or utilities, which reduce taxable profit when recorded in accounts.

An expense in New Zealand accounting is a cost a business incurs in its operations to generate revenue. Expenses reduce taxable profit and appear in the profit and loss statement. Common expenses include wages, rent, utilities, advertising, and depreciation.

The Inland Revenue (IRD) allows deductions for business-related expenses, provided they are incurred in earning income.
