Understanding Business Expense Claims in NZ

Running a business involves a multitude of expenses, but there are ways to cut costs by claiming certain business-related expenses on your taxes. If you are a business owner, you have the opportunity to claim various expenses incurred in the process of generating income, which helps reduce taxable income and allows you to retain more of your hard-earned revenue.

Business Like can help you understand common business expense claims in compliance with IRD regulations to help you minimise expenses and improve your financial health.

A business expense claim is a deduction that business owners in New Zealand can apply to reduce their taxable income by the costs incurred in running their business. These expenses must be directly related to generating business income and are intended to reflect the operational costs necessary for day-to-day functions. When correctly claimed, business expense deductions help lower the total tax payable, allowing business owners to retain more of their revenue.

To make a claim, the expenses must be documented, reasonable, and directly connected to the business. The Inland Revenue Department (IRD) has guidelines on what constitutes a business expense, and keeping accurate records is essential to ensure compliance and maximise your deductions.
You can consult with expert chartered accountants at Business Like to ensure that you maximise business expense claims NZ and remain compliant with IRD regulations.



Common Business Expense You Can Claim in New Zealand


Vehicle Expenses

For vehicles used partly or fully for business purposes, you can claim a percentage of related expenses, including fuel, maintenance, insurance, registration, and depreciation. If your vehicle is used for both personal and business trips, the percentage of business use—determined by keeping a 90-day logbook—dictates the portion you can claim. 

For example, if you use the vehicle 60% for business, you can claim 60% of all associated costs. Alternatively, the IRD mileage rate (e.g., 79 cents per km) can be used for occasional business use of a personal vehicle.

Travel Expenses

Business-related travel expenses, such as flights, accommodation, and meals, are fully deductible. You can claim travel costs for trips between business locations, overseas business travel, and travel for asset or equipment purchases. However, commuting between home and a regular place of business isn’t deductible, unless your home is also your primary business base. 

Most travel expenses are deductible in the income year incurred, but prepaid travel expenses over $14,000 or for trips starting more than six months after your balance date may need to be spread across years.







How to Claim Business Expenses in New Zealand

Now that you’re familiar with common business expenses you can claim, the next step is understanding how to claim business expenses nz with the Inland Revenue Department (IRD). Follow these steps to ensure a smooth and compliant process.

  • Business expenses are claimed on your income tax return. Small businesses and sole traders include these deductions on their IR3 or IR4 forms. If you are using accounting software like Xero, categorise expenses appropriately to streamline this process.
  • If your business is GST-registered, you can also claim the GST portion of your business expenses. Be sure to keep GST invoices, and include these claims in your GST returns.
  • IRD mandates that businesses keep accurate records of all claimed expenses. Keep receipts, invoices, bank statements, and any other evidence of the transaction. For mixed-use expenses, like a vehicle or home office, maintain records that distinguish between business and personal use.
  • For complex expenses, like asset depreciation or tax planning, consider consulting an accountant. A professional can help ensure you’re maximising your deductions while staying compliant with IRD guidelines.
