Claiming motor vehicle expenses

What you can claim for Motor Vehicle Expenses

If you have a vehicle expense that is partly for your business and partly for your private use, you can claim the proportion that relates to your business. 

Motor Vehicle Expenses can include:

  • Petrol
  • Repairs & maintenance
  • Insurance
  • Warrant of Fitness fees
  • Registration fees
  • Road user charges

Sole Trader & Partnership

If you are a sole trader or partnership, you can have a choice of two methods to claim motor vehicle expenses for business use of a motor vehicle. It is based on the actual costs incurred in business use of vehicle or an amount calculated using the kilometer rate method.

  • Actual Costs Method

Under the actual costs method, the motor vehicle expenses are calculated by multiplying the actual costs by the proportion of business use. You need to keep accurate records of all actual costs incurred including details of private and business-related expenses. You can work out the business use of your vehicle by keeping a logbook or you can claim up to 25% of all vehicle expenses. You could be asked the justify the percentage claimed.

  • Kilometer Rate Method

Under the kilometer rate method, the motor vehicle expenses are calculated by multiplying the IRD’s kilometer rate by the total kilometers travelled in the year by the proportion of business use.

From the 2019/2020 year, there are two tiers of kilometer rate that can be applied to calculate your motor vehicle expenses.

  • Tier one: The tier one covers your vehicle’s fixed and running costs. This rate will apply with respect to the first 14,000 km per year.
  • Tier two: The tier two only covers running costs. Once vehicle has travelled more than 14,000 km per year, tier two rate must be applied.

You can work out the business use of your vehicle by keeping a logbook for at least 90 consecutive days. If no logbook is kept, the use of Tier one rates is limited to the first 3,500kms. Your calculation can be used for up to 3 years if the proportion of business use does not change by more than 20%. After 3 years you will need to keep a logbook for another 90 days.


Company can use the same methods above for a sole trader & partnership if it is a close company (5 or fewer shareholders) and only one or two motor vehicles are used by shareholder-employees for their private use.

You can claim GST on the purchase price of the motor vehicle. If you do this, you can claim GST on the proportion that relates to your business. You could be required to adjust the GST claimed if the actual business use is different to the original GST claim.


"When I first found Consol accounting on Google I thought that they must be too good to be true. Then I talked to them on the phone and I was almost certain they were too good to be true. Luckily for us they weren’t. The customer service, price and ease of use make this company out of this world. I could not recommend them any more. They are utterly seamless to integrate and effective as can be. "

Curtis and Katie Hacon Director, FiTiki Limited

"I had put off finding an accountant for a while because of the cost and perceived hassle however after my first consult with Consol, I immediately wished I had connected with them sooner. Consol are responsive, affordable and easy to deal with. Being able to outsource this aspect of my business has allowed me to focus more energy on the parts of my work that I love. "

Dr Rebecca Herald Clinical Psychologist

"I have been most impressed with Consol accounting team since I made the switch last year. The ‘Switching over’ process was really simple, after the initial set up process I can track and log my company’s financial activity with ease and accuracy. By far the most efficient and helpful service I’ve had with accounting companies. Thank you"

Vivien Ye Aesthetic Nurse Specialist, Vivip Limited

"I started out in full-time private practice over a year ago and also registered as a limited company. I love doing my work and seeing my clients, but I soon discovered just how much time doing the financials could take up. In the first year, I worked on my own tax returns and company statements, but was unsure I had done them “right” and really wanted an accountant’s expertise and guidance. From my first phone call to Andrew Joo of Consol Accounting Limited, I could tell that this service would meet my needs. He has been quick to respond, patient with me, great at teaching lots and is a Xero master user. I find the system easy to use now, and feel encouraged to get the most out of my business and confident in knowing that I will meet my tax obligations. Compared to how long it took me to struggle at doing this on my own, there is clear value in getting the professionals to do my accounting."

Stefan Dyke Director, SLHE Consulting Limited

"I would genuinely recommend Consol for all your financial and accounting needs. I needed an accountant quickly to help me find my feet starting up a rapid business. I genuinely had hundreds of thoughts and questions and wanted to do things right first time ... it was all a bit daunting, exciting and a steep learning curve. Andrew Joo was so supportive as he instantly responded to all my needs and then coached me through a solution and helped me understand the minefields at first . It’s really easy now the business is booming and all my accounting is taken care of so I can enjoy the fruits of my labour. I still reach out occasionally and have the answer super quick.. thanks to Consol."

Karl Jones Director, Retail Resilience

"I had just started out in business and soon realised that someone was going to have to help me with my accounting and tax compliance functions. I was very conscious of the need to be vigilant about incurring any new costs, consequently I did a fair bit of research. I came up with the conclusion that I could get everything I wanted, under one roof, from Consol Accounting, at the most competitive rate I could find on the market. It was a win-win. After joining their team I discovered there were a lot of loose ends to sow-up before I could start functioning effectively, and focus solely on running the business side. Andrew, the Founder from Consol Accounting, was an absolute God-send. He was very personal and approachable, and made setting everything up from scratch so easy and so quickly. I’ve basically been running on auto-pilot each month ever since. Just as I had planned. Thanks for your service, guys, best decision I made."
