ATO Ute Logbook Rules 2026–27: 1-Tonne Dual-Cab Utes, Car Log Book Apps & Km Trackers

Short answer: Under ATO motor vehicle rules for 2026–27, whether you use the standard 12-week car logbook (or 91c/km rate) versus actual commercial vehicle costs depends on your ute’s payload capacity. A ute with a payload under 1 tonne is treated as a “car,” meaning you choose between the 91c/km cents-per-kilometre method (up to 5,000 km) or a 12-week ATO car logbook. A one-tonne-plus ute is an “other vehicle”—you cannot use 91c/km, and instead claim actual business costs backed by receipts and a representative ute logbook.

Almost every Australian sparkie, plumber, carpenter, landscaper, and builder drives a dual-cab or single-cab ute—a Toyota HiLux, Ford Ranger, Isuzu D-Max, Mitsubishi Triton, or Mazda BT-50. Yet thousands of sole-trader tradies make a costly mistake on their tax return: they assume every ute qualifies for the 91 cents per kilometre rate (or that every dual-cab ute is automatically “100% tax deductible with no logbook”).

In reality, the Australian Taxation Office (ATO) divides utes into two completely different legal categories based on the 1-tonne (1,000 kg) payload test. Below is how to check which rule applies to your ute in 2025–26 and 2026–27, when you need a ute logbook, and how to choose a car log book app or km tracker without 24/7 GPS battery drain.

Is my tradie ute a “car” or an “other vehicle” under ATO rules?

The ATO defines a car as a motor vehicle (including a four-wheel drive or light dual-cab ute) designed to carry a load of less than 1 tonne (1,000 kg) and fewer than 9 passengers. Any ute or van designed to carry a load of 1 tonne or more is classified by the ATO as an other vehicle (commercial vehicle).

To work out your ute’s payload (carrying capacity), use the official ATO formula from your manufacturer compliance plate or RedBook spec sheet:

$$\text{Payload Capacity (kg)} = \text{Gross Vehicle Mass (GVM)} - \text{Kerb Weight (Unladen Mass)}$$

Ute Payload Category	Examples (Check Your Exact Variant’s GVM − Kerb Weight)	Can You Use 88c / 91c per km?	Can You Use the 12-Week Car Logbook Method?	Does the $69,883 Car Depreciation Limit Apply?
Under 1,000 kg payload (“Car”)	Many high-spec dual-cab 4×4 utes (e.g., Ranger Raptor, some HiLux Rogue / SR5 or heavy canopy builds where kerb weight reduces payload below 1,000 kg)	Yes — up to 5,000 business km ($4,400 in 2025–26; $4,550 in 2026–27)	Yes — 12 continuous weeks valid for 5 years	Yes — capped at $69,883 ($6,353 max GST credit) unless exempt
1,000 kg or more payload (“Other Vehicle”)	Most single-cab cab-chassis utes, space-cab utes, and standard work-spec 4×2 / 4×4 dual-cabs rated at ≥ 1,000 kg payload	No — strictly prohibited	Actual Costs Method — apportion real expenses using a representative ute logbook / diary	No — commercial vehicles ≥ 1 tonne are outside the passenger car limit

For the passenger-car rules, see our 12-week ATO car logbook guide and ATO cents per kilometre guide (88c & 91c).

Do I still need a ute logbook if my ute carries 1 tonne or more?

Yes, if there is any private use at all. This is the #1 myth on Australian building sites. Many tradies hear about “exempt commercial vehicles” and assume a 1-tonne ute requires zero records and can be claimed at 100% even if they take it to the beach, do the school drop-off, or tow a boat on Sunday.

Here is what the ATO actually requires for a 1-tonne+ ute owned by a sole trader:

1. You can only deduct the business-use percentage of actual costs: Even for a 1-tonne+ ute, ATO motor vehicle deduction rules state you can only claim the percentage of fuel, registration, insurance, tyres, servicing, loan interest, and depreciation that relates to business travel.
2. How you prove your business-use percentage: While the formal 12-week statutory “car” logbook under Division 28 applies to cars under 1 tonne, the ATO explicitly advises keeping a ute logbook or representative diary (typically over 4 to 12 continuous weeks, plus start-of-year and end-of-year odometer readings) showing the date, odometer start/finish, kilometres, and job purpose so you can prove why you claimed 85% or 92% business use during an audit.
3. What about the “minor and infrequent private use” rule (PCG 2018/3)? Practical Compliance Guideline PCG 2018/3 is an FBT safe-harbour for eligible workhorse utes where travel is strictly between home and work (carrying bulky tools or driving an eligible commercial vehicle) and private travel is wholly minor, infrequent, and irregular (for example, no more than 1,000 km of total private travel in the year and no single return private journey exceeding 200 km). Even then, keeping an odometer and trip log is how you prove your private travel stayed within those tight boundaries.

When can a tradie claim ute travel between home and the job site?

Normally, driving from home to a regular workplace is private commuting. However, for a sole-trader tradie driving a ute, home-to-site travel is generally deductible as business travel in two common situations:

• Your home is your base of operations: You run your sole-trader business from home, store your materials and tools there, and drive directly to different customer job sites, quotes, and trade wholesalers each day.
• You transport bulky tools and equipment: You must carry heavy ladders, drop saws, compressors, conduit, or toolboxes that cannot be left securely on the building site overnight.

What should you look for in a car log book app or km tracker in Australia?

When tradies search the App Store or Google for a car log book app, ute logbook, km tracker, or drivers note (Driversnote), they usually compare three types of apps:

Feature / Requirement	Always-On Background GPS Apps (e.g., Driversnote, MileIQ, Everlance)	ATO myDeductions (ATO App)	On-Device Job & Odometer Logbook (Keel)
Records Odometer Start & End Readings?	Often relies on GPS distance unless you manually enter odometer checks	Yes	Yes — built around exact odometer spans + job reasons
Battery Drain & 24/7 Location Tracking?	High — tracks every weekend family trip in the background	Optional GPS or point-to-point	Zero background GPS drain — log trips intentionally in 1 line
Links Each Trip to a Customer Quote / Invoice?	No — separate from your invoicing and job costing	No — cannot issue ABN Tax Invoices or quotes	Yes — every ute trip links directly to the customer job (Job #042)
Captures Fuel & Servicing Tax Invoices (1B GST)?	Mileage focus; limited BAS GST reporting	Annual myTax upload only	Yes — on-device Vision OCR captures fuel & servicing dockets with 10% GST
Pricing Model (AUD)	~$15 to $25+/month subscription after low free-trip cap	Free	Free core app; optional one-time Lifetime or statutory pack

What must every entry in an ATO ute logbook or car log book app show?

Whether your ute is under 1 tonne (requiring a 12-week car logbook) or 1 tonne and over (using a representative diary to apportion actual costs), record these five items for every trip:

1. Date of the journey (start and finish date);
2. Odometer reading at the start and end of the trip (not just GPS kilometres—the ATO specifically checks that trip kilometres reconcile with your dashboard odometer);
3. Total kilometres travelled;
4. Specific business reason for the trip (e.g., “Reece Plumbing Burwood to 18 Station St, Box Hill — hot water replacement Job #109”, never just “Business”); and
5. Opening and closing odometer readings on 1 July and 30 June of every financial year.

Worked example: 1-tonne dual-cab ute claim for 2026–27

Liam is a GST-registered carpenter driving a dual-cab 4×4 cab-chassis ute with a 1,080 kg payload (GVM 3,200 kg minus kerb weight 2,120 kg). Because the payload is over 1 tonne, he uses the Actual Costs Method:

• Annual odometer (1 July 2026 – 30 June 2027): 28,000 km total.
• Ute logbook result: 25,200 km business travel (quotes, Bunnings/timber yard pickups, and job sites) = 90% business use.
• Actual running costs (GST-exclusive): Diesel fuel $5,600 + Rego & CTP $1,150 + Comprehensive commercial ute insurance $1,850 + Servicing & all-terrain tyres $2,100 + Loan interest $1,900 + Depreciation/write-off $7,400 = $20,000.
• Deductible ute claim on tax return: $20,000 × 90% = $18,000 (nearly four times the $4,550 cents-per-km cap!), plus 90% of the GST credits on eligible tax invoices at Label 1B on his quarterly Simpler BAS.

Frequently asked questions

Can I use the 91 cents per km rate for a 1-tonne tradie ute in 2026–27?

No. The ATO cents per kilometre method (88c/km in 2025–26 and 91c/km in 2026–27) is legally restricted to “cars”—vehicles designed to carry a load of less than 1 tonne and fewer than 9 passengers. If your ute has a payload capacity of 1,000 kg or more, you must claim the business percentage of your actual running costs backed by receipts and a trip log.

How do I check if my dual-cab ute has a 1-tonne payload for the ATO?

Subtract your ute’s Kerb Weight (unladen mass, including a full tank of fuel and standard factory equipment) from its Gross Vehicle Mass (GVM). If the result is 1,000 kg or more, the ATO classifies it as an “other vehicle” (commercial vehicle). Many high-trim dual-cab 4×4 utes have payloads between 820 kg and 960 kg, which makes them “cars” that can use the 12-week car logbook or 91c/km method.

Do I need a logbook for a dual-cab ute if I am a sole trader?

Yes, whenever the ute has any private use. Even if your ute has a payload over 1 tonne, you can only deduct the business-use portion of fuel, registration, insurance, servicing, and depreciation. Keeping a representative ute logbook with odometer readings and job reasons is how you prove your business-use percentage if the ATO reviews your return.

Why do tradies switch from background GPS apps like Driversnote to an odometer logbook?

Background GPS mileage trackers run location services 24/7, which drains your iPhone battery on site and records every private weekend drive to the shops or footy, forcing you to sort hundreds of personal trips at tax time. An intentional odometer logbook lets you record work trips in one line and link each trip directly to the customer job and invoice.

Does the ATO accept a digital car log book app instead of a paper book?

Yes. The ATO accepts electronic logbooks and km trackers provided they capture every required detail—specifically the vehicle details, start and end dates, opening and closing odometer readings for each trip and for the financial year, kilometres travelled, and a specific business reason in English—and can be exported and kept for five years.

Can I claim fuel for my ute without keeping fuel dockets?

Under both the passenger car logbook method and commercial vehicle actual-cost rules, the ATO prefers tax invoices for fuel (and you must hold valid tax invoices over $82.50 incl. GST to claim the 10% GST credit on your quarterly BAS). For income tax, if a fuel receipt is missing, fuel and oil can be estimated from your annual odometer readings, fuel consumption rate, and average retail fuel prices.
