Business vehicle expenses in NZ: records to keep
To claim business vehicle expenses in New Zealand, keep evidence of your business travel and the vehicle costs behind your claim. A logbook helps explain how much of a mixed-use vehicle belongs to the business.
The method determines the paperwork
Keep accurate records of both business and private vehicle use. Inland Revenue sets out the rules for actual costs and kilometre rates, and explains how a logbook can support the business share. Follow the current guidance for the vehicle and method you choose (see Inland Revenue — Claiming vehicle expenses).
Make the distance explainable
A useful working record connects a journey with its date, business purpose and distance. Keep the unit clear, especially if you work across borders or use several platforms. Save the source behind any total you transfer into a tax calculation.
A contractor might group travel by job or customer; a driver might check platform statements against their own journey record. Either way, the useful question at year end is whether you can trace the total back to the work that produced it.
Where platform statements fit
Keep the statement's distance exactly as printed, including its label and period. If the same distance appears on a weekly and annual statement, compare the periods before combining them. A clear record lets you identify the overlap.
In Bilbx, distance explicitly printed on a payout statement is saved with its label and unit. Use that evidence alongside your other vehicle records when checking the business travel behind a claim.
Keep expenses with the vehicle records
Store the receipts and supporting documents you will use for the method you choose. Mark the vehicle or job in a way that will still make sense months later. Our income record guide explains how to connect customer payments and project costs.
