Navigating the ins and outs of business expenses and tax deductions can feel overwhelming for many New Zealand business owners. However, understanding what expenses you can claim can significantly reduce your taxable income, ensuring you don’t pay more tax than necessary. Fortunately, the New Zealand tax system is clear about which business expenses are deductible, and with the help of professionals like GCOL Chartered Accountants, you can make sure you’re maximizing your claims. What Are Business Expenses in New Zealand? In simple terms, business expenses are the costs incurred in the day-to-day running of your business. These expenses are essential to generating your business income and are therefore deductible, meaning you can subtract them from your revenue to determine your taxable income. The New Zealand Inland Revenue (IR) Department has guidelines to help business owners understand what expenses are claimable. Here's a breakdown of the most common claimable business expenses: 1. Operating Expenses These are the costs involved in keeping your business running. Examples include: Rent and Utilities : The cost of renting office space or premises, as well as utilities like electricity and water, are claimable. Insurance : Premiums for business insurance (e.g., property, liability, and vehicle insurance) are deductible. Advertising and Marketing : Costs associated with promoting your business, such as online ads, print advertising, and marketing campaigns, can be claimed. Office Supplies : Items such as paper, pens, computers, and other office-related expenses are eligible for deduction. Bank Fees and Interest : Fees for business accounts and interest on business loans are deductible. 2. Vehicle and Travel Expenses If you use your vehicle for business purposes, you can claim a portion of the vehicle expenses, which may include: Fuel, Repairs, and Maintenance : If your vehicle is used for business, you can claim the costs proportionate to business use. Travel Expenses : Airfares, accommodation, and meals while traveling for business purposes are deductible. Remember, personal use of the vehicle or travel expenses cannot be claimed. You will need to apportion these costs based on business use. 3. Employee and Contractor Costs If you have employees or contractors, the following are claimable expenses: Salaries and Wages : Payments to employees, including bonuses, holiday pay, and KiwiSaver contributions, are deductible. Contractor Fees : If you hire independent contractors, their fees are also claimable. Training and Development : Costs associated with training and developing your team are deductible, so long as they are relevant to your business. 4. Depreciation Some business assets, such as equipment, vehicles, or buildings, lose value over time. Instead of claiming the full cost in one go, you can claim depreciation on these assets. The IRD provides depreciation rates for various asset types. 5. Professional Services If you hire professionals to assist with your business, their fees are claimable, including: Accountant and Legal Fees : Fees for financial advice, tax preparation, or legal assistance related to business activities can be deducted. Consulting Fees : If you engage business consultants for services such as market research or business planning, these expenses are also claimable. 6. Home Office Expenses Many small business owners or sole traders work from home. If this applies to you, you can claim a portion of your home-related expenses, such as: Mortgage Interest or Rent : If you work from home, you can claim a percentage of your mortgage interest or rent based on the portion of your home used for business. Electricity and Internet : You can also claim a portion of your electricity, phone, and internet costs based on the percentage of time you use them for business.
