5 Tax Deductions NZ Small Businesses Often Miss
Most small business owners leave thousands of dollars on the table each year by missing legitimate tax deductions. Here are five of the most commonly overlooked deductions every NZ business owner should know about — from home office expenses to vehicle use and professional development.
Key Deductions Covered:
- ✓ Home office expenses (a portion of rent/mortgage, power, internet)
- ✓ Vehicle and travel costs for business use
- ✓ Professional development, training, and subscriptions
- ✓ Business-related meals and entertainment (50% deductible)
- ✓ Equipment depreciation and capital allowances
1. Home Office Expenses
If you run your business from home — even part time — you may be able to claim a portion of your rent or mortgage interest, rates, power, and internet. The key is calculating the percentage of your home used exclusively for business. IRD has a specific formula, and getting it right can add up to a significant deduction.
2. Vehicle and Travel Costs
Business-related vehicle use is deductible — but you need to keep a logbook to substantiate your claim. You can claim the business percentage of fuel, insurance, repairs, and depreciation. Alternatively, IRD's mileage rate (currently 95 cents/km for the first 14,000km) can be used for the first 3 months if you don't have a logbook.
3. Professional Development & Subscriptions
Courses, conferences, industry memberships, and software subscriptions that are directly relevant to your business are all deductible. This includes professional association fees, trade journal subscriptions, and online learning platforms like LinkedIn Learning.
