Running a business in New Zealand comes with a mix of opportunities and responsibilities, and understanding business expenses is one of the most important aspects of managing your company finances. Knowing what expenses you can claim—and what you shouldn’t—can help you save money, remain compliant with the law, and avoid unnecessary penalties.

What Are Business Expenses?

Business expenses are costs incurred in the process of running your company. These are generally deductible from your taxable income, reducing the amount of tax your company needs to pay.

Common types of expenses include:

• Office rent and utilities
• Employee salaries and benefits
• Business-related travel and accommodation
• Marketing and advertising costs
• Professional fees, such as accounting or legal services
• Equipment, software, and tools used for business operations.

Claiming Business Expenses Correctly

In New Zealand, claiming expenses incorrectly can lead to tax penalties. The Inland Revenue Department (IRD) expects businesses to maintain clear records and only claim expenses that are wholly and exclusively for business purposes.

Do’s:

• Keep detailed receipts for every business expense
• Record the date, amount, and purpose of each expense
• Use separate business accounts to avoid mixing personal and company costs
• Consult with a qualified accountant for clarity

Don’ts:

• Claim personal or family expenses as business costs
• Overstate or fabricate expense amounts
• Fail to keep supporting documentation

Common Grey Areas

Some expenses can be partly for business and partly personal. For example:

• Home office costs: If you work from home, you can claim a portion of rent, utilities, or internet, but only the percentage used for business.
• Vehicle expenses: If you use a car for both personal and business trips, you must calculate the business portion accurately.

In these cases, it’s important to keep detailed logs to support your claims.

Why Accurate Expense Management Matters

Proper expense management:

• Reduces your taxable income, saving money legally
• Ensures compliance with New Zealand tax laws
• Protects you in case of an IRD audit
• Helps you track business profitability and make informed decisions

Failing to manage expenses correctly can lead to fines, audits, or even legal action.
