Sales representatives are among the highest-mileage workers in Australia. Client meetings, territory rounds, product demonstrations, and conferences mean your car is essentially a mobile office. A well-documented sales representative car expenses tax deduction can deliver one of the largest refunds at tax time — but only if you claim correctly.
This guide covers what travel qualifies, how to handle car allowances, which method to choose, and the records the ATO expects.
What travel qualifies for sales reps
You can claim a deduction for car expenses when you use your own vehicle for work-related travel. For sales representatives, qualifying journeys include:
- Driving from your office or home base to client sites
- Travelling between client meetings during the day
- Attending trade shows, conferences, or product launches
- Visiting warehouses, distribution centres, or supplier premises
- Transporting product samples or demonstration equipment
Your regular commute from home to the office (and back) is not deductible unless your home qualifies as your base of operations — which it may if your employer does not provide you with a fixed workplace and you start and end your rounds from home.
Choosing a claiming method
Cents per kilometre
Claim 88 cents per business kilometre (2025–26 rate), capped at 5,000 km. Maximum deduction: $4,400. Most sales reps blow past 5,000 business kilometres within a few months, so this method rarely captures your full entitlement.
Logbook method
Complete a 12-week logbook to establish your business-use percentage, then apply it to your total car expenses (fuel, registration, insurance, servicing, depreciation). No kilometre cap applies.
For sales reps covering large territories, the logbook method routinely produces deductions of $8,000 to $15,000 or more per year. The 12-week recording period pays for itself many times over.
For step-by-step instructions on keeping a compliant logbook, see our ATO logbook requirements guide.
Handling car allowances
Many employers pay sales reps a car allowance — a set amount per kilometre, per week, or per year to cover vehicle costs. Here is how it works at tax time:
- Car allowances are assessable income. They appear on your income statement and you must declare them.
- You then claim your actual car expenses as a deduction. If your expenses exceed the allowance, you benefit from the difference. If they are less, the net effect is a small amount of extra taxable income.
- Reimbursements are different. If your employer reimburses the exact cost of each trip (receipt-based), that amount is generally not assessable income and no further deduction is available.
Always check whether your employer’s payment is classified as an allowance or a reimbursement — the tax treatment is very different. See our car allowance Australia guide for a detailed explanation.
What records sales reps need
For cents per kilometre: A trip log recording the date, kilometres, destination, and work purpose for each journey. An app like Tripbook captures this automatically and generates reports you can share with your accountant.
For the logbook method: A completed 12-week logbook, plus receipts for fuel, servicing, insurance, registration, and any other car expenses. You also need odometer readings at the start and end of the financial year.
For car allowances: Records of the allowance amount, how it was calculated, and how it appears on your income statement.
Keep everything for at least five years after lodging your return.
Other deductions for sales reps
- Phone and data — the business portion of your mobile plan
- Laptop, tablet, and accessories — if you use them for work and they cost under $300, claim immediately; over $300, depreciate
- Client entertainment — note that entertainment expenses are generally not deductible for employees, but check if your employer includes them in your package via FBT
- Product samples — if you purchase demonstration stock yourself
- Parking and tolls — work-related only
Common mistakes to avoid
Claiming the home-to-office commute when you have a fixed workplace. If your employer provides an office and you choose to drive to clients from home, only the travel beyond your normal commute distance may qualify.
Overlooking depreciation. Under the logbook method, the decline in value of your car is a significant expense. The ATO car cost limit for 2025–26 is $69,674 — this caps the depreciable amount for passenger vehicles.
Not reconciling allowances. Failing to declare your car allowance as income while claiming the deduction can trigger an ATO review. Both sides of the equation must appear in your return.
Claiming on your tax return
Sales rep car expenses are claimed at Item D1 — Work-Related Car Expenses if you are an employee. Choose your method, enter the figures, and ensure any car allowance is also declared as income.
If you are a self-employed sales agent or contractor, claim through your business schedule instead and review our contractor car expenses guide.
Consistently tracking every client visit and territory drive in Tripbook means your sales representative car expenses tax deduction is backed by solid data — exactly what the ATO expects.
