Sole Trader Tax Deductions Australia: The Complete List for 2026

Running your own business in Australia means wearing every hat – accountant, marketer, salesperson, admin. But at tax time, there is one hat worth putting on properly: the one that saves you money.

Sole trader tax deductions in Australia reduce your taxable income. Every legitimate business expense you claim means less tax you pay to the ATO. And yet, thousands of Australian sole traders overpay each year because they miss deductions or lose the receipts to prove them.

This guide covers every major tax deduction category available to sole traders with an ABN for the 2025-26 financial year. We will keep each section brief and link to detailed guides where you need more depth. By the end, you will know exactly what you can claim, what you cannot, and how to keep records the ATO will accept.

Tax rules change. This guide reflects ATO rules current as of April 2026. Always consult a qualified tax professional for advice specific to your situation.

How Sole Trader Tax Deductions Work in Australia

As a sole trader, you report your business income and expenses in your individual tax return. There is no separate business tax return – everything flows through your personal return using the business and professional items schedule.

To claim a tax deduction, the expense must meet three ATO tests:

1. It was for your business, not personal use. A new laptop for client work qualifies. A gaming console does not.
2. It directly relates to earning your income. There must be a clear connection between the expense and your business activity.
3. You can prove it. You need records – receipts, invoices, bank statements – showing what you spent, when, and why.

If an expense is partly personal and partly business, you can only claim the business portion. Sarah, a freelance graphic designer in Brisbane, uses her phone 70% for business. She claims 70% of her phone plan as a tax deduction and keeps a four-week diary each year to support the split.

The Australian tax year runs from July 1 to June 30. You need to lodge your tax return by October 31 (or later if you use a registered tax agent). Sole traders who are registered for GST also need to lodge Business Activity Statements (BAS) – quarterly or monthly depending on your turnover.

Here is a breakdown of the main deduction categories.

Vehicle and Travel Deductions

If you drive for business – visiting clients, picking up supplies, attending meetings – your vehicle costs are deductible. The ATO gives you two methods to calculate your claim.

Cents per km method: Claim 88 cents per kilometre for the 2025-26 financial year, up to a maximum of 5,000 business kilometres. No receipts for fuel or servicing needed, but you must be able to show how you calculated your business kilometres.

Logbook method: Keep a logbook for at least 12 continuous weeks to establish your business-use percentage. Then apply that percentage to your actual car costs – fuel, registration, insurance, servicing, depreciation, and finance interest.

Ben runs a mobile dog grooming business in Perth. He drives to 8-10 clients per day and clocks well over 5,000 business kilometres each year. The logbook method saves him roughly $3,200 more per year than the cents per km method because his actual running costs are high and his business-use percentage is 85%.

Other travel costs you can claim:

• Airfares, trains, buses, and taxis for business trips
• Accommodation and meals during overnight business travel
• Tolls and parking fees for business journeys
• Rideshare fares (Uber, Didi) for business travel

You cannot claim the cost of travelling between home and your regular place of work. That is a private expense in the ATO’s view.

See our complete guide to ATO cents per km rates for a full breakdown of both methods, including how to set up a logbook.

Working from Home Deductions

Many sole traders work from home at least part of the time. The ATO offers two approaches for claiming home office expenses.

Fixed rate method: Claim 70 cents per hour you work from home. This rate covers electricity, phone, internet, stationery, and computer consumables. You can claim the decline in value of depreciating assets (like furniture and technology) separately on top of this rate.

Actual cost method: Calculate the actual work-related portion of each expense – electricity, heating, cooling, phone, internet, office furniture depreciation, and cleaning costs for your dedicated office. This takes more record keeping but can yield a higher claim if you have a dedicated workspace.

To claim home office expenses, you must have a dedicated work area (a room, a desk, a defined space) and records of the hours you work from home.

Read our work from home deduction guide for step-by-step instructions on both methods and which one suits your setup.

Office, Equipment, and Technology

This is one of the biggest deduction categories for sole traders. If you buy something for your business, it is almost certainly deductible.

Office Supplies and Consumables

• Stationery, printer ink, paper
• Postage and shipping costs
• Cleaning supplies for your workspace

Phone and Internet

Claim the business percentage of your mobile phone plan and home internet. If you have a separate business phone line, claim 100% of it. Keep a diary for at least four weeks each year to establish your business-use percentage.

Software and Subscriptions

• Accounting software (Xero, MYOB, QuickBooks)
• Design tools (Adobe Creative Cloud, Canva Pro)
• Project management (Asana, Trello, Monday)
• Cloud storage (Google Workspace, Dropbox Business)
• Industry-specific tools and SaaS subscriptions

These are fully deductible in the year you pay for them.

Computers, Equipment, and the $20,000 Instant Asset Write-Off

For assets costing less than $20,000, you can claim the full cost as an immediate deduction under the instant asset write-off. This applies to businesses with an aggregated turnover under $10 million and is currently active until June 30, 2026.

This covers laptops, desktops, tablets, printers, cameras, tools, and any other equipment you buy for your business. If the asset costs $20,000 or more, you depreciate it over its effective life instead.

Mia, a freelance photographer in Melbourne, bought a $4,500 camera body and a $2,800 lens in March 2026. She claimed the full $7,300 as an instant asset write-off that financial year instead of spreading the deduction over several years.

Professional Services and Insurance

Professional Services

• Accountant and tax agent fees
• Bookkeeper fees
• Legal advice and services related to your business
• Business consultant fees
• Debt collection fees

Your tax return preparation fee from the previous year is deductible this year. If your accountant charges $600 to prepare your 2024-25 return, you claim that $600 in your 2025-26 return.

Insurance Premiums

• Public liability insurance
• Professional indemnity insurance
• Income protection insurance (if replacing business income)
• Business asset insurance (equipment, stock, tools)
• Workers compensation (if you have employees)

You cannot claim the cost of life insurance or personal health insurance as a business deduction.

Marketing and Advertising

Every dollar you spend promoting your business is deductible:

• Website hosting, domain registration, and design fees
• Google Ads, Facebook Ads, Instagram promotions
• Business cards, flyers, brochures, and signage
• Social media management tools
• Email marketing platforms (Mailchimp, ConvertKit)
• SEO and content marketing costs
• Sponsorships and promotional events
• Photography and video production for marketing

If you pay a graphic designer to create your logo or a copywriter to build your website content, those costs are deductible too.

Training and Professional Development

You can claim education expenses that directly relate to your current business activity:

• Courses, workshops, and seminars related to your trade
• Industry conferences (including travel and accommodation)
• Professional membership fees and subscriptions
• Trade journals and industry publications
• Books and online courses that maintain or improve your current skills

The key word is “current.” You can claim a photography course if you are a working photographer. You cannot claim a photography course if you are a plumber looking to change careers – that is considered a new qualification, not maintaining existing skills.

Other Deductions Sole Traders Often Miss

• Bank fees and merchant charges – Transaction fees, monthly account fees on your business account, EFTPOS terminal costs
• Interest on business loans – Including interest on equipment finance and business credit cards (business portion only)
• Superannuation contributions – Contributions you make to your own super fund are tax deductible up to the annual cap
• Union and association fees – Industry body memberships, trade union dues
• Bad debts – If a client never pays an invoice you already declared as income, you can claim the bad debt as a deduction
• Repairs and maintenance – Fixing business equipment, maintaining tools, office repairs
• Cost of trading stock – Raw materials, goods you buy to resell, packaging

What You Cannot Claim

Not everything passes the ATO’s test. These are common mistakes:

• Private expenses disguised as business costs. Your morning coffee is not a business deduction just because you drink it before starting work.
• Entertainment expenses. Taking a client to dinner is generally not deductible (there are limited exceptions for fringe benefits tax purposes).
• Clothing – unless it is a compulsory uniform, protective gear, or occupation-specific (like a chef’s checked pants). Everyday work clothes, even if you only wear them for work, are not deductible.
• Fines and penalties. Speeding tickets, parking fines, and ATO penalties are never deductible.
• Private portion of mixed expenses. If your phone is 30% business, you cannot claim 100%.
• Capital expenses over the write-off threshold – These must be depreciated, not claimed in full immediately.
• Commuting costs – Travel between home and your regular workplace.

Getting this wrong can trigger an ATO review. When in doubt, check with your tax agent.

Record Keeping for Sole Traders

The ATO requires you to keep records for five years from the date you lodge your tax return. This applies to:

• Receipts and invoices for all business expenses
• Bank and credit card statements
• Vehicle logbooks and travel diaries
• Home office hour records
• Asset purchase records and depreciation schedules
• Income records (invoices you sent, payment confirmations)

Paper receipts fade. Email receipts get buried. The ATO accepts digital copies as long as they are a true and clear reproduction of the original.

> Tip: SparkReceipt’s expense tracker lets you scan paper receipts, forward email receipts, and organize everything by category – automatically. When your accountant asks for your records, export a clean report in one click.

See ATO record keeping requirements for the full list of what to keep and how long.

What you can claim without receipts – yes, there are situations where the ATO allows claims without a physical receipt. We explain when and how.

GST and BAS Basics

If your sole trader business turns over $75,000 or more per year, you must register for Goods and Services Tax (GST). For rideshare and taxi drivers, registration is required from the first dollar regardless of turnover.

Once registered, you:

• Charge GST (10%) on your goods and services
• Claim GST credits on your business purchases
• Lodge a Business Activity Statement (BAS) – usually quarterly

Your BAS reports the GST you collected from customers minus the GST you paid on business expenses. The difference goes to (or comes back from) the ATO.

Keeping clean records of every purchase with an ABN and a valid tax invoice is critical for claiming GST credits. Without the right documentation, you cannot claim the credit even if you paid the GST.

If your turnover is under $75,000, GST registration is optional. Some sole traders register voluntarily so they can claim GST credits on their purchases.

Frequently Asked Questions

How much can a sole trader earn before paying tax in Australia?

The tax-free threshold for individuals (including sole traders) is $18,200 for the 2025-26 financial year. You pay no tax on the first $18,200 of your total taxable income. Above that, standard individual tax rates apply.

Do sole traders need an ABN to claim tax deductions?

You need an ABN to operate as a sole trader, and your ABN is what identifies your business activity on your tax return. You claim sole trader deductions through the business section of your individual tax return. Without an ABN, you cannot access certain concessions like the instant asset write-off.

Can I claim tax deductions without receipts in Australia?

For expenses under $10, the ATO does not always require a receipt if you can show the expense was incurred (for example, through a bank statement). For everything else, you need written evidence. The ATO can disallow deductions if you cannot back them up with records.

What is the instant asset write-off for sole traders in 2026?

Sole traders with an aggregated annual turnover under $10 million can immediately deduct the full cost of eligible business assets costing less than $20,000 each. This applies to assets first used or installed ready for use by June 30, 2026.

Do I need to register for GST as a sole trader?

Only if your business turnover is $75,000 or more per year (or any amount for rideshare and taxi services). Below that threshold, registration is optional. If you do register, you charge 10% GST on your sales and can claim GST credits on your business purchases.

Can I claim the cost of my home office as a sole trader?

Yes. You can claim a portion of your home expenses (electricity, internet, phone, furniture depreciation) using either the fixed rate method (70 cents per hour) or the actual cost method. You need a dedicated work area and records of the hours you work from home.
