The Inland Revenue Department (IRD) has updated its guidance on the Square Metre Rate method for calculating home office expenses. This simplified approach allows self-employed individuals, contractors, freelancers, and small business owners to claim eligible home office deductions without tracking individual utility expenses. The method covers household running costs such as electricity, internet, insurance, and water while requiring rent, mortgage interest, and council rates to be calculated separately. Understanding the latest IRD home office expense rules can help New Zealand taxpayers maximise deductions and remain compliant with tax regulations.
Home-based businesses continue to play an important role in New Zealand’s economy. To simplify expense claims, Inland Revenue provides a Square Metre Rate method that reduces administrative work while allowing eligible taxpayers to claim legitimate business expenses.
This approach is particularly beneficial for sole traders, consultants, freelancers, contractors, and self-employed professionals who operate from a dedicated workspace within their homes.
The Square Metre Rate is a simplified calculation method approved by Inland Revenue for home office expense claims.

The method helps reduce compliance costs while maintaining consistency in tax reporting.

The calculation combines the IRD square metre rate with the business-use portion of occupancy expenses.
10 × $55.60 = $556
10% × $10,400 = $1,040
$556 + $1,040 = $1,596
