How to Claim a Business Vehicle in New Zealand (2026 Guide)

Quick answer

A business vehicle in New Zealand is claimed either through Inland Revenue’s all-in kilometre rates or through the actual-cost method: the business share of running costs plus depreciation, with the share set by a 90-day logbook valid for up to three years. GST-registered businesses claim 15% on the purchase to the extent of business use. Company vehicles available for private use bring FBT, unless the work-related vehicle exemption genuinely applies.

Is a vehicle tax deductible in New Zealand?

Yes, at the business share, with the method decided per vehicle when it enters the business. Inland Revenue gives four routes for petrol, diesel, hybrid and electric vehicles: a logbook to set the business share, 25% of running costs without a logbook, the kilometre rates, or actual costs, and you stick with the one you choose for as long as you own the vehicle ^[1] . The kilometre-rate route needs no receipts: business kilometres times the tiered, fuel-type-specific rates, with depreciation and every running cost inside the rate. The actual-cost route claims the business percentage of real spend (fuel, insurance, registration, repairs, tyres) and adds depreciation on the vehicle at IRD’s published rate for its class. The percentage comes from a logbook kept at least 90 consecutive days, valid for up to three years unless business use changes by more than 20% ^[2] .

A vehicle bought on or after 22 May 2025 that is new, or new to New Zealand even if it was used overseas, can qualify for Investment Boost: 20% of its cost is deducted as an expense when it’s first available for use, and depreciation is claimed on the remaining 80% ^{[4] [5]} . Second-hand assets already used in New Zealand don’t qualify ^[5] .

Companies sit outside the choice: they claim actual costs, and the question moves to who uses the vehicle. A vehicle available to an employee for private use is a fringe benefit, FBT is payable per day of availability, and the well-known escape hatch is narrow: the work-related vehicle exemption for sign-written utes, vans, and similar vehicles whose private use is limited to home-to-work and incidental travel, restricted in writing and actually policed.

How much can you claim?

Worked example under actual costs: a builder’s $52,000 ute runs $9,400 of annual costs (fuel, insurance, repairs, registration) and depreciates at IRD’s rate for the class. His 90-day logbook shows 82% business use, so the year’s claim is 82% of running costs, $7,708, plus 82% of the depreciation. Had he adopted the kilometre rates when the ute entered the business, the whole claim would instead be his business kilometres through the 2025-26 tiers (diesel: $1.30 Tier 1, 38c Tier 2), covered in the fuel guide.

GST on vehicles

A GST-registered business claims the 15% GST on a vehicle purchase according to its intended taxable use, and adjusts in later periods if actual use diverges: a 100% claim on a vehicle that then does school runs invites exactly that adjustment. Running costs follow the same business-share logic from the logbook. The kilometre rates, being an income tax simplification, carry no GST claim; businesses wanting input tax on vehicle costs need the actual-cost records.

Record-keeping requirements

Seven years for everything: purchase documents, the 90-day logbook and each renewal, odometer readings, running-cost receipts, the depreciation schedule, and for FBT-exempt work vehicles, the written private-use restriction and evidence it is checked. The logbook drives both the income tax and GST apportionments, so it is the document a review reaches for first.

How to claim, step by step

1. Decide the method when the vehicle enters the business: kilometre rates or actual costs. The choice is per vehicle and endures.
2. For actual costs, run the 90-day logbook and set the business-use percentage; diary the three-year renewal.
3. Claim the business share of running costs and depreciation in the IR3 or company return, or apply the tiered rates to business kilometres instead.
4. If GST registered, claim input tax on the purchase and running costs at the business share.
5. For a company vehicle, decide the FBT position honestly: available for private use means FBT, unless the work-related vehicle exemption is documented and real.
6. On sale, account for depreciation recovered if the vehicle sells above book value.

Common mistakes

• Claiming depreciation on top of the kilometre rates.
• A 100% GST claim on a vehicle with obvious private use.
• Treating a sign-written double-cab as automatically FBT-exempt without the written restriction the exemption requires.
• Letting the logbook lapse past three years.
• Forgetting depreciation recovery when the vehicle sells for more than book value.

Software that helps

• Driversnote produces the 90-day logbook and tracks the business percentage the whole claim rests on.
• ExpenseFlow captures the purchase invoice and running costs, applies the 15% GST treatment to the business share, flags vehicle spend for apportionment, and syncs approved transactions to Xero or QuickBooks Online.
• Xero holds the fixed-asset register for the depreciation schedule and the disposal entry.
