⚡ Key Takeaways
- Car deductions are one of the ATO’s top audit targets in 2026. ABC’s June 2026 tax coverage reports the ATO explicitly warning Australians that car and work-related travel expenses are a “repeat problem area” — with many people wrongly claiming home-to-work trips and private vehicle costs. [4]
- There are only two methods for employees: cents-per-kilometre (88c/km for 2025-26, maximum $4,400; rising to 91c/km and $4,550 from 1 July 2026) and the logbook method (12-week logbook, actual costs, business-use percentage). You cannot mix and match — pick one per car per year. [2][3]
- Home-to-work travel is not deductible — it is private travel, regardless of how far you commute or how many tools you carry. This is the most common car deduction error the ATO sees. [2][4]
- For someone legitimately driving 3,000–5,000 km a year for work, the cents-per-km method produces $2,640–$4,400 in deductions — worth $792–$1,628 in actual tax saved at a 30% marginal rate. Many people with genuine work travel under-claim because they’re afraid of getting it wrong. [5][7]
- The ATO car limit for 2025-26 is $69,674 — the maximum vehicle value used to calculate depreciation for business owners. Luxury Car Tax thresholds are $91,387 (fuel-efficient) and $80,567 (others). [1]
- Novated lease and employer-provided cars are dealt with under FBT — you cannot claim the running costs of a novated-lease vehicle as a work-related car deduction in your personal return. [2]
Car Tax Deductions Australia 2026: Are You Claiming Correctly?
By The Fine Print editorial team | Last updated: June 2026 | 12 min read | ⚠️ Not financial advice
Car expenses are one of the biggest legitimate work-related deductions available to Australian employees — and one of the most commonly misunderstood. The ATO has made vehicle claims an explicit focus area in 2026, because the errors run in both directions: people claiming home-to-work commutes and private costs they’re not entitled to, and people with genuine work travel not claiming the thousands of dollars they could. In 2026, the cents-per-km rate is rising, the car limit has been updated, and the ATO is watching. Here’s how to get your claim right.📋 What’s in This Guide

Who Can Claim Car Expenses — and What Qualifies
The ATO allows employees to claim work-related car expenses if they own or lease the car (not a novated lease or employer-provided vehicle), use it for work-related travel, pay the costs themselves without reimbursement, and have the required records to substantiate the claim. [2]Work-related travel that qualifies includes: driving between two different workplaces (e.g. your main job and a second job); travelling from your workplace to another location for work (client sites, meetings, field work); carrying heavy or bulky equipment that can’t be left at work and there’s no secure storage; and — in some limited circumstances — travelling directly from home to an alternate workplace (not your regular office). [2]⚠️ What you cannot claim: Ordinary home-to-work travel — regardless of distance, what you carry, or how inconvenient public transport is. Car expenses for a vehicle under a salary-sacrifice/novated lease arrangement (those are handled under FBT). Running costs for a car your employer pays for or reimburses. Private trips, errands, school runs and anything not directly connected to earning your income. The home-to-work exclusion is the #1 source of incorrect car claims and the ATO flags it every year. [2][4]
The Two Methods: Cents-Per-Km vs Logbook
Method 1: Cents-per-kilometre
The simpler option. You claim a set rate per kilometre of genuine work-related travel, up to a maximum of 5,000 km per car. For 2025-26, the rate is 88 cents per km — giving a maximum deduction of $4,400. From 1 July 2026, the rate rises to 91 cents per km, lifting the maximum to $4,550 for 2026-27 returns. [2][3]No receipts are required, but you must be able to explain and justify how you calculated your work kilometres. The ATO accepts diaries, calendars, job records, calendar entries, and similar documents. “I drove 5,000 km for work” without any supporting evidence is not enough — the ATO’s data-matching and risk models flag automatic 5,000 km claims as a recurring problem. [2][5]💡 Who cents-per-km suits best: Employees who do occasional work travel — visiting client sites, attending off-site meetings, driving between two workplaces — but whose total work kilometres are under 5,000 a year. It’s low-admin, no receipts required, and produces meaningful deductions: 3,000 km × 88c = $2,640; 5,000 km × 88c = $4,400. At a 32.5% marginal rate, that’s $858–$1,430 in actual tax saved. [5]
Method 2: Logbook method
The more complex — but potentially more valuable — option. You keep a 12-week logbook of all trips in the car (work and private), calculate what percentage of total kilometres were for work purposes, and apply that percentage to your actual running costs for the full year. Running costs include fuel or electricity, servicing and repairs, registration, insurance, tyres, depreciation (or lease costs), and interest on a car loan. [6][8][9]The 12-week logbook must be continuous, cover a period representative of your usual travel patterns, and record for each business trip: the date, purpose, start and end odometer readings, and kilometres driven. A logbook is valid for five years if your work-use pattern doesn’t change significantly — but you must still keep fuel and maintenance receipts each year to substantiate your actual costs. [6][10]💡 Who logbook suits best: People with high annual work kilometres (over 5,000 km, since cents-per-km caps at that), high running costs (expensive car, lots of fuel), or a high work-use percentage where applying that percentage to actual costs beats the cents-per-km calculation. It requires more admin but can produce significantly larger deductions — particularly for tradespeople, sales reps, and healthcare workers who regularly drive to multiple sites. [7][6]
2025-26 and 2026-27 Rates, Car Limits and GST Caps
- Cents-per-km rate 2025-26: 88c/km, max 5,000 km, max deduction $4,400. Use this rate for the return you’re lodging now.
- Cents-per-km rate 2026-27: 91c/km from 1 July 2026, max 5,000 km, max deduction $4,550. This applies to your 2026-27 return lodged from July 2027.
- ATO car limit 2025-26: $69,674 — the maximum car value for calculating depreciation for business use.
- Luxury Car Tax thresholds 2025-26: $91,387 for fuel-efficient vehicles; $80,567 for all others.
- Maximum GST credit 2026-27: $6,353 (1/11 of the $69,883 car limit) — even if the car costs more and the GST component is higher, the credit is capped. [11]
Common Mistakes the ATO Flags Every Year
The ATO and independent accounting firms consistently identify the same errors in car claims. Knowing them in advance is the most effective way to avoid an audit or an amended assessment. [12][4][2]⚠️ The four most common car deduction errors:
- Claiming home-to-work travel as a work deduction. It isn’t. The daily commute is private travel even if your employer is far away, you start work early, or there’s no public transport. The only exception is where home is your primary place of business and you’re travelling to another work location — that’s a specific situation that needs to be established properly.
- Automatically claiming 5,000 km without a reasonable basis. The ATO’s risk models flag this. If 5,000 km is your genuine figure, document it. If it isn’t, scale back.
- Claiming for vehicles that aren’t “cars” under the rules. Many one-tonne utes and trucks are classified as “non-car” work vehicles under the ATO definition, and different rules (and potentially more generous deductions) apply. If you drive a ute, check whether it qualifies as a car under ATO rules before applying the cents-per-km or logbook method.
- Using the logbook method without a valid 12-week logbook. You cannot estimate your business-use percentage without completing a compliant logbook. If you don’t have one and want to use logbook for 2025-26, you cannot apply the method retroactively.
Business Owners: Instant Write-Offs, Depreciation and Car Limits
For self-employed people and business owners, car expenses are deducted differently — through the business, not as an individual employee deduction. If the car is used for both business and private purposes, only the business portion is deductible, and you need evidence of that percentage (a logbook, or a reasonable basis). [13][1]The most common business owner errors with car expenses involve: claiming full instant asset write-offs or depreciation on cars that exceed the $69,674 car limit (you can only depreciate up to the limit, not the full purchase price); not apportioning for private use (the car that drives kids to school cannot be 100% business-deductible); and misunderstanding how EVs and commercial vehicles are treated — electric vehicles may have different depreciation treatment and the GST rules differ between passenger vehicles and commercial ones. [13][14][11]✅ Three Moves to Claim Correctly — and Keep the ATO Off Your Back
Action 1: Choose the right method for your situation right now
Do this calculation before you lodge: multiply your genuine work kilometres (excluding home-to-work travel) by 88c and see what you get. Then estimate what the logbook method might produce — your total annual car costs multiplied by an honest estimate of your business-use percentage. If the logbook number is materially higher and you have (or can start) a valid logbook, that method is worth pursuing. If your genuine work kilometres are under 5,000 and your costs are modest, cents-per-km is simpler and produces a clean, documentable claim. The key point is to make the choice deliberately — not just default to whichever seems easiest, because the easier one might be leaving significant deductions unclaimed. [2][5][6]Action 2: Fix your logbook and records before 30 June if you need them
If you intend to use the logbook method for your 2025-26 return and don’t currently have a valid 12-week logbook, you need to act immediately — the logbook must cover 12 continuous weeks, and ideally those weeks should fall within the income year you’re claiming for. Start the logbook now, even if it extends into the 2026-27 year; there are rules about how a logbook spanning two years can be used. The logbook needs to record for every business trip: the date, purpose of the trip, start odometer, end odometer, and kilometres. Keep every receipt for fuel, servicing, registration, insurance and repairs — you’ll need these to calculate your actual running costs. Use a logbook app (several are ATO-compliant and auto-calculate business-use percentages) or a pre-printed paper logbook. [8][10][9]Action 3: Audit your claim against the ATO “can’t claim” rules before lodging
Before you finalise any car deduction, run through the ATO’s checklist of what you cannot claim: remove any home-to-work trips; remove school runs, shopping and personal errands; if the car is novated-leased, remove all running costs (those are an FBT matter, not a personal deduction); and don’t claim 5,000 km unless you can explain and substantiate that number. If you’re unsure whether a trip qualifies, the ATO’s guidance says it needs to be “directly related to earning your income” — not just tangentially connected to your work. When in doubt, scale back the claim rather than pad it. The ATO’s data-matching and risk-scoring for car claims in 2026 means inflated or unusual claims are more likely to trigger a review than in previous years. [4][2][15]❓ Frequently Asked Questions
What is the cents-per-km rate for 2025-26?
88 cents per km for 2025-26, maximum 5,000 km, maximum deduction $4,400. Rising to 91c/km and $4,550 from 1 July 2026. No receipts needed, but you must be able to justify your work km count. [2][3]Can I claim my daily commute?
No. Home-to-regular-workplace travel is private and not deductible. Qualifying work travel includes driving between two workplaces, visiting client sites, and carrying bulky tools with no secure storage at work. [2][4]How does the logbook method work?
Keep a 12-week logbook of all trips, calculate your business-use percentage, then apply that to your actual annual running costs (fuel, rego, insurance, servicing, depreciation). Valid for 5 years if use doesn’t change. Requires all running-cost receipts. [6][9][10]Can I claim a novated lease car?
No — novated lease cars are handled under FBT, not as a personal work-related car deduction. Claiming running costs for a novated-lease vehicle in your personal return is an error the ATO regularly flags. [2]⚖️ The Fine Print Verdict
Car deductions used to be the lazy way to pump up a tax refund — stick in 5,000 km, collect the cheque. In 2026, they’re one of the fastest ways to land on the ATO’s radar. The game has shifted from “How much can I claim?” to “Can I prove every kilometre I’m claiming?” — and most people’s logbooks and habits haven’t caught up. The good news is that if you genuinely drive for work, the correct claim can be worth $1,000–$2,000 in real tax savings. The bad news is you need records to get there. Start now: document your kilometres, decide on your method, and audit your claim against the ATO’s rules before you lodge. The people who get caught aren’t always the fraudsters — they’re often just the ones who were sloppy with paperwork.
👉 Know your method. Document your kilometres. Remove what you can’t prove. And if you have genuine work travel — don’t leave money on the table by under-claiming.
