About Tax Savings for New Zealand Sole Traders

Commonly Missed Deductions

  • Home office expenses: Claim NZ$5/week using the flat-rate method — no complex calculations needed. Alternatively, claim the actual business proportion of rent/mortgage interest, power, internet, and insurance. Many sole traders forget to claim this consistently.
  • Motor vehicle expenses: Use the IR kilometre rate method (NZ$1.04/km for the first 14,000km in 2024/25) for simplicity, or the logbook method for higher-use vehicles. Business travel to client sites, suppliers, and professional events is deductible. Keep a mileage log.
  • Professional development: Courses, webinars, industry conferences, and trade publications directly related to your current work are all deductible. Many sole traders forget smaller online courses purchased throughout the year.
  • Phone and internet: The business portion of your personal phone and internet bill is deductible. Track your usage pattern and claim the business percentage — even 30-40% of a NZ$120/month combined bill adds up to NZ$500+ per year.

Tax Planning Tips

  • Provisional tax management: If you expect your residual income tax to exceed NZ$5,000, set aside approximately 28-35% of each payment received. Pay provisional tax on time to avoid use-of-money interest charges from Inland Revenue.
  • GST registration timing: Once your turnover approaches NZ$60,000, plan your GST registration carefully. Once registered, you can claim back GST on business purchases — which can be a significant benefit if you have substantial business expenses.
  • Year-end timing: The NZ tax year ends 31 March. Consider timing large business purchases before year-end to maximise deductions in the current tax year. Sole traders can use the low-value asset threshold (NZ$1,000) to immediately expense qualifying equipment.

Frequently Asked Questions

How much should a NZ sole trader set aside for tax?

A good rule of thumb is to set aside 28-35% of your net business income. At lower income levels (under NZ$48,000), you can set aside around 28%. As your income grows into higher tax bands, increase this to 33-35% to cover income tax and ACC Levy.

What is the km rate for vehicle expenses in NZ?

For 2024/25, the Inland Revenue kilometre rate is NZ$1.04 per kilometre for the first 14,000 business kilometres. Above 14,000km, the rate is NZ$0.38/km. The km rate covers all vehicle running costs including petrol, insurance, registration, and repairs.

Can I claim the low-value asset threshold immediately?

Yes. From 17 March 2021, New Zealand sole traders can immediately deduct the full cost of business assets costing NZ$1,000 or less (excluding GST if you are GST-registered). Assets costing more than NZ$1,000 must be depreciated over time.
