Sales Worker Tax Deductions 2025-26: Claim Rules and Examples

General information only. Speak with a registered tax agent for advice.

Sales workers who travel between clients, carry samples, and use their personal phone to close deals have genuinely above-average deduction potential. The ATO specifically publishes benchmark data for sales occupations, which means claims that sit well above peers will attract scrutiny. Every deduction must satisfy the same three rules: the expense must be work-related, not reimbursed, and backed by written evidence. Mixed-use expenses — car, phone, internet — must be apportioned.

What you can claim

Deduction	Typical range	Key rule
Car expenses — travel between client sites	$1,500–$7,000	Logbook method preferred for high-km reps. 88c/km (up to 5,000 km) suits lower-use roles. Travel from home to your first client can be claimable if you don’t have a fixed office base.
Mobile phone (work portion)	$300–$900	Keep a 4-week usage diary. Sales roles often justify 60–80% work use. Claim the plan cost plus any handset depreciation.
Internet (work portion)	$100–$400	Apportion based on actual work use at home. Typically 30–50% for hybrid workers.
Briefcase, laptop bag, or sample case	$50–$300	A bag used specifically to carry work materials, samples, or a laptop is deductible. A general-purpose backpack used daily is harder to justify.
Samples and demonstration materials	$100–$500	Items you personally purchase and carry for client demonstrations, not covered by your employer, qualify. Keep receipts and note the business purpose.
Home office expenses	$200–$800	67c/hour fixed rate for every hour genuinely worked from home. Or claim actual running costs. Keep a diary of WFH hours.
Professional development and sales training	$300–$1,000	Sales technique courses, product certification, industry conferences. Must be relevant to your current role — not a step toward a different career.
Professional memberships	$100–$400	Industry association fees (e.g., sales and marketing bodies) directly related to your current work.
Stationery and work materials	$50–$250	Items you buy yourself and are not reimbursed for: notepads, pens, printed proposals, folders.
Tools and equipment (work-specific)	$50–$500	Presentation gear, USB drives, portable chargers used for work. Items over $300 must be depreciated.
Tax agent fees	$150–$400	Fully deductible in the year you pay the invoice.

What you cannot claim

• Suits, business shirts, and general workwear. The ATO is firm: clothing worn to look professional is a private expense. Only a compulsory uniform with an employer logo qualifies. A “dress code” is not the same as a uniform.
• Client lunches and entertainment. Entertainment expenses are specifically denied under s 32-5 of ITAA 1997. Taking a client out for lunch to build the relationship is not deductible, even if it’s a normal part of your job.
• Parking at your regular office. Parking fees at your normal place of work are private. Parking at a client’s premises or an off-site meeting is deductible.
• Home-to-office commute. Travel from home to your primary office is never deductible, even if you make calls on the way or load samples into the car at home.
• Personal mobile plan costs. The private portion of your phone bill — personal calls, streaming, social media — must be excluded from any claim.

Worked example

Liam is a pharmaceutical sales representative in Brisbane earning $88,000 in base salary plus $12,000 commission (total $100,000) in 2025-26. He drives between medical practices five days a week and works from home on Friday afternoons.

Item	Amount
Car expenses (logbook, 68% work use, $11,000 total car costs)	$7,480
Mobile phone (70% work, $1,440 annual plan)	$1,008
Internet (35% work, $840 annual)	$294
Sales training and product certification	$650
Industry association membership	$220
Home office (67c × 150 hours)	$101
Briefcase and sample carrier	$180
Stationery and printed materials	$120
Tax agent fee	$275
Total deductions	$10,328

At Liam’s marginal rate of 32% (30% + 2% Medicare), these deductions reduce his tax by approximately $3,305.

ATO audit triggers

• High car claims with no logbook. Using the cents-per-kilometre method at the maximum 5,000 km without records to support the claim is a known audit trigger for sales workers.
• 100% phone claims. Claiming the entire cost of a mobile plan without apportionment implies no personal use — the ATO does not accept this for a standard phone plan.
• Entertainment claimed as “client meeting” costs. Restaurant receipts described as business meetings are specifically targeted by ATO data-matching through the hospitality industry reporting.
• Large deductions in commission-low years. If your commission drops but deductions spike, the ATO’s benchmarking tools will flag the pattern.

Records you need

• Logbook for any car claim — 12 consecutive weeks recording every trip: date, odometer start/end, destination, and reason.
• 4-week phone diary noting work calls and work-related data use to support your apportionment percentage.
• Receipts for all items over $300, and ideally for everything you claim.
• Confirmation from employer that expenses were not reimbursed, especially for samples, travel, and conference costs.
• WFH diary with dates and hours if using the fixed-rate home office method.

Key takeaways

• Car travel between client sites is your highest-value deduction — a 12-week logbook is worth completing if you cover significant distance.
• The entertainment deduction does not exist in Australia. Lunch with clients is a personal cost.
• Phone and internet claims must be apportioned — a defensible diary beats a round percentage.
• Keep all records for 5 years from the date you lodge your tax return.
