ABN Tax Return 2026: Complete Guide for Sole Traders

Q: Do I need receipts for ABN deductions?

Yes. You should keep receipts, invoices, bank records, platform statements, logbooks and other evidence to support both income and deduction claims. A deduction without records is a confident opinion, not a supported claim.

Quick answer

If you earn income through an ABN in Australia, you may need to include that income in your 2026 tax return.

That includes income from:

sole trader work
contracting
freelancing
rideshare driving
delivery work
consulting
trade work
personal services
side-hustle income
small business activity
platform income
cash jobs
online work

Having an ABN does not mean tax has already been taken out.

That is the bit that causes trouble.

Employees usually have tax withheld from wages. ABN workers often do not. So when tax time arrives, your ABN income, expenses, records and business deductions all need to be handled properly.

GoTax helps Australians complete ABN tax returns online, with returns checked by registered tax agents before lodgement.

What is an ABN tax return?

An ABN tax return is not a separate magical tax return form that floats around wearing a business hat.

For many people, it means your individual tax return includes your ABN income and business expenses.

This is common for:

sole traders
individual contractors
freelancers
self-employed workers
rideshare drivers
delivery drivers
personal trainers
consultants
tradies
cleaners
creatives
side-hustle operators

If you operate as a sole trader, your business income generally forms part of your individual tax return.

That means your personal income and ABN income are dealt with together.

Very convenient.

Also very easy to stuff up if you ignore the ABN section and hope it quietly disappears.

It won’t.

Who is this guide for?

This guide is for Australians who are individuals earning business or contractor income.

That includes people who say things like:

“I have an ABN but I also have a job.”
“I did some contractor work this year.”
“I drive Uber or delivery.”
“I freelance on the side.”
“I invoice clients.”
“I started a small business.”
“I got paid without tax taken out.”
“I am self-employed.”
“I have no idea what I can claim.”

That last group is large.

Possibly the largest business category in Australia.

This package is built for those people.

Choose the right GoTax path

Different ABN workers have different tax return needs.

Use the page that best fits your situation:

Your situation	Best GoTax page
You have an ABN and need to lodge	ABN Tax Return
You run a small sole trader business	Small Business Tax Return
You are a contractor	Contractor Tax Return
You are a freelancer	Freelancer Tax Return
You work for yourself	Self-Employed Tax Return
You drive rideshare or delivery	Rideshare Tax Return

This package will spread those topics properly.

Not every ABN worker is the same.

A freelancer, a rideshare driver and a brickie may all have an ABN.

Their tax records do not look the same.

Their gloveboxes may, but that is a separate issue.

Does having an ABN mean you must lodge a tax return?

If you have ABN income, you usually need to deal with it in your tax return.

The key issue is not simply whether you have an ABN.

The key issue is whether you earned income, carried on business activity, or had reportable business amounts.

You may need to lodge if you had:

ABN income
sole trader income
contractor income
freelance income
rideshare income
delivery income
business income
platform income
cash business income
income with no tax withheld
GST or business reporting obligations
PAYG instalments
business losses or deductions

The ATO does not ignore business income just because it was small.

There is no “tiny side hustle invisibility cloak”.

Disappointing, but fair.

Read the GoTax support article: Do I Need to Lodge a Tax Return with an ABN?

ABN income you must declare

ABN income is not just the money that arrived in your bank account with a nice neat invoice number.

It can include:

invoices paid by clients
cash jobs
platform payments
rideshare income
delivery income
marketplace income
consulting income
freelance income
labour-only contract income
trade income
online service income
commissions
tips connected to the business
grants or subsidies where assessable
income from multiple business activities

If you earned it through your ABN or business activity, check whether it needs to be declared.

“Cash” does not mean “optional”.

It means “annoying to reconcile if you did not keep records”.

The ATO receives information from many sources.

Banks, platforms and clients often leave a trail.

So does poor record keeping, just less usefully.

ABN income and PAYG wages can sit in the same return

Many people have both:

employee income, and
ABN income

Example:

Mia works part-time as an employee and does freelance design work through her ABN.

Her 2026 tax return may include:

Income type	Where it fits
Employee wages	Salary and wages section
Tax withheld	PAYG withholding credits
Freelance income	Business income / ABN income
Freelance expenses	Business deductions
Bank interest	Interest income
Other deductions	Personal or work-related deductions

The employee income may already have tax withheld.

The ABN income may not.

That is why ABN income can create a tax bill if nothing has been put aside.

The tax office is not being rude.

It is just catching up.

Why ABN workers often get a tax bill

ABN workers often receive income before tax is taken out.

That means the money landing in your account is not necessarily all yours to keep.

A shocking design flaw.

Common reasons ABN workers get a tax bill include:

no tax withheld from ABN income
not putting money aside
GST confusion
claiming too few deductions
claiming deductions incorrectly
missing PAYG instalments
income higher than expected
private expenses claimed as business expenses
HELP debt or Medicare adjustments
poor records

If you earn ABN income, you should think about tax as you go.

Waiting until July and hoping the numbers behave is not a strategy.

It is tax roulette in thongs.

What can ABN workers claim?

ABN deductions depend on your actual business activity.

The general idea is simple:

You may be able to claim expenses that are directly connected to earning your business income.

Common ABN deduction areas include:

tools
equipment
software
phone
internet
home office
vehicle expenses
business insurance
advertising
website costs
accounting and tax agent fees
platform fees
payment processing fees
training
subscriptions
stationery
protective clothing
business bank fees
contractor costs
materials and supplies

But there is a catch.

There is always a catch.

Private expenses are not automatically deductible just because you have an ABN.

An ABN does not turn your entire life into a business expense.

It just gives the ATO more categories to question.

Read the GoTax guide: ABN Tax Deductions Guide: What You Can Claim

Business vs private use

Many ABN expenses have mixed use.

That means part business, part private.

Examples include:

Expense	Possible issue
Mobile phone	Business and personal use
Internet	Work, streaming, family use
Car	Business trips and private driving
Laptop	Client work and personal use
Home office	Business space and household use
Tools	Business work and private projects
Software	Business and personal use

You need to claim only the business-related part.

Example:

You pay $1,200 for phone and internet during the year.

You reasonably calculate 40% business use.

Potential business claim:

$1,200 × 40% = $480

Not $1,200.

Not “I used it for work once, therefore all of it”.

Tax law remains allergic to wishful maths.

ABN car expenses

Car expenses are a major ABN tax issue.

They are also a major source of creative fiction.

ABN workers may be able to claim business-related vehicle use, but private use needs to be separated.

Common business travel may include:

travel to client sites
travel between jobs
delivery driving
rideshare driving
travel to buy business supplies
travel between business locations
work-related site visits
mobile service calls

Private travel may include:

school drop-offs
groceries
weekend driving
private errands
commuting that is not genuinely business travel
personal trips mixed into business days

ABN workers may need to consider:

logbook records
business kilometre records
odometer readings
fuel and servicing records
private-use percentages
GST treatment, if registered
whether the vehicle is a car for tax purposes

If you drive for rideshare or delivery, your car may be central to your income.

Use the dedicated GoTax page: Rideshare Tax Return

For the broader car deduction rules, read: Logbook vs Cents per Kilometre 2026

Home office for ABN workers

ABN workers often claim some form of home office expense.

This can be legitimate, but it needs care.

You may need to consider:

electricity
internet
phone
office equipment
software
desk and chair
stationery
occupancy costs in limited cases
business-use percentage
private-use percentage
whether the home is genuinely used for business

Home office claims are different depending on your facts.

A freelancer working from a dedicated home workspace is not the same as someone answering two client emails from the couch.

The couch is not a business premises.

It is a snack platform with cushions.

Freelancers should use: Freelancer Tax Return

Self-employed workers should use: Self-Employed Tax Return

Contractors and personal services income

Contractors need to be careful.

Some contractor income may be personal services income, often called PSI.

Broadly, PSI is income mainly produced from your personal skills or efforts.

This matters because PSI rules can affect deductions and how income is treated.

Contractors should watch for:

labour-only arrangements
one main client
being paid for personal skill or effort
limited business structure
no real business assets
no ability to delegate
working much like an employee
sham contracting concerns

You can still be a genuine contractor and have PSI issues.

The words on the invoice do not decide everything.

Calling yourself “Chief Independent Strategic Solutions Consultant” also does not decide everything.

Although it may improve your LinkedIn profile.

Use the GoTax contractor page: Contractor Tax Return

Freelancers and creators

Freelancers often have messy income and useful deductions.

That includes people in:

design
writing
photography
marketing
consulting
web development
social media
content creation
admin support
bookkeeping support
virtual assistant work
tutoring
coaching

Freelancer income may come from:

invoices
platforms
retainers
one-off projects
subscriptions
digital product sales
commissions
overseas clients

Freelancer deductions may include:

laptop
software
internet
phone
home office
subscriptions
website costs
advertising
training
business insurance
equipment
platform fees
accounting and tax costs

Freelancers need records because the income often arrives from multiple places.

Your inbox is not a bookkeeping system.

It is a digital compost heap with search.

Small business sole traders

A sole trader small business can be simple.

It can also be a drawer full of receipts and three bank accounts arguing with each other.

Common sole trader businesses include:

trades
cleaning
consulting
tutoring
beauty services
fitness
delivery work
creative services
home-based services
market stalls
online selling
professional services

Sole traders should keep clear records of:

sales
invoices
cash received
bank deposits
business expenses
private-use calculations
vehicle records
home office records
GST records, if registered
PAYG instalments
equipment purchases
business loans
insurance
tax agent fees

Use the broad GoTax page: Small Business Tax Return

Do you need GST for your ABN?

GST is separate from income tax.

That is important.

You can have an ABN without being registered for GST.

You may need to register for GST if your GST turnover reaches the required threshold.

For many businesses, the key threshold is $75,000.

Rideshare drivers have special GST issues, so do not assume the ordinary small-business approach applies neatly to every platform activity.

If you are registered for GST, your records need to handle:

GST on sales
GST credits on purchases
BAS reporting
tax invoices
business/private apportionment
timing issues
GST-inclusive and GST-exclusive amounts

GST is where “I’ll sort it out later” becomes a lifestyle choice.

A bad one.

Read: Do I Need GST for My ABN?

What records do ABN workers need?

ABN records are the backbone of the return.

You should keep records of:

invoices issued
income received
bank deposits
platform statements
receipts
supplier invoices
equipment purchases
car records
logbooks
odometer readings
home office calculations
phone and internet bills
insurance
software subscriptions
business loan interest
GST records, if registered
payroll or contractor payments, if relevant
tax agent fees
business bank fees
payment processing fees

ATO record keeping is not decoration.

It is how you prove the return.

A deduction without records is just a confident opinion.

Can you claim startup costs?

New ABN workers often spend money before the first proper income arrives.

That may include:

business registration costs
website setup
domain name
insurance
business cards
tools
equipment
software
training
advertising
professional advice
licences
subscriptions

Some costs may be deductible.

Some may need to be depreciated.

Some may be capital or private.

Some may just be a bad idea with a logo.

The key is to identify what the cost was for and whether it relates to starting or carrying on the business.

Common ABN tax mistakes

ABN mistakes are usually predictable.

Avoid these:

Mistake	Why it hurts
Not declaring ABN income	The ATO may data match it
Forgetting cash income	Cash is still income
Claiming private expenses	Private costs are not business deductions
No records	Weakens deductions
Mixing personal and business spending	Creates messy calculations
Ignoring GST	Can create compliance issues
Not putting tax aside	Can lead to a tax bill
Claiming car use without records	High review risk
Copying last year	Business facts change
Thinking ABN means everything is deductible	It does not

The most dangerous sentence in ABN tax is:

“I’ll just claim it.”

That sentence has caused more tax trouble than most people realise.

Right up there with:

“My mate said.”

ABN tax return checklist

Before lodging your 2026 ABN tax return, check:

all ABN income included
cash income included
platform income included
invoices reconciled
bank deposits checked
expenses recorded
private use removed
business-use percentages calculated
car records kept
logbook checked
phone and internet apportioned
home office calculated
equipment records kept
GST reviewed
PSI considered, if relevant
tax agent fees included
PAYG instalments included
bank details correct
old estimates not copied blindly

If that list feels annoying, good.

It is doing its job.

Annoying before lodgement is better than painful after lodgement.

Frequently asked questions

Do I need to lodge a tax return if I have an ABN?

If you earned ABN income, had business activity, or have reportable business amounts, you may need to include that information in your tax return. Having an ABN by itself is not the only issue. The income and activity matter.

Is an ABN tax return separate from my personal tax return?

For many sole traders, ABN income is included in the individual tax return. The business income and expenses are reported as part of that return.

What income do I need to declare with an ABN?

You may need to declare invoices, cash jobs, platform income, rideshare income, delivery income, freelance income, consulting income, contractor income and other business income.

Can I claim expenses with an ABN?

You may be able to claim expenses directly related to earning your business income, such as tools, equipment, phone, internet, software, car expenses, home office costs and business insurance. Private use must be removed.

Does having an ABN mean everything is tax deductible?

No. An ABN does not turn private expenses into business deductions. The expense must relate to earning assessable income and records should be kept.

Do I need receipts for ABN deductions?

Yes, you should keep receipts, invoices, bank records, platform statements, logbooks and other evidence to support income and deduction claims.

Do I need GST if I have an ABN?

Not always. GST is separate from having an ABN. GST registration generally depends on turnover and business type. Rideshare and some activities can have special GST issues.

Can I lodge an ABN tax return online?

Yes. GoTax helps ABN workers, sole traders, contractors, freelancers, self-employed workers and rideshare drivers complete tax returns online.

Can GoTax help with contractor tax returns?

Yes. GoTax has a dedicated Contractor Tax Return service page for contractors and ABN workers.

Can GoTax help with freelancer tax returns?

Yes. GoTax has a dedicated Freelancer Tax Return page for freelancers and independent workers.

What records do ABN workers need to keep for their tax return?

ABN workers should keep records of invoices issued, income received, bank deposits, platform statements, receipts, supplier invoices, equipment purchases, car records, logbooks, odometer readings, home office calculations, phone and internet bills, insurance, software subscriptions and GST records if registered.

What are common ABN tax mistakes to avoid?

Common ABN tax mistakes include not declaring cash income, forgetting platform income, claiming private expenses as business deductions, keeping no records, mixing personal and business spending, ignoring GST obligations, not putting tax aside, claiming car use without records, and assuming everything is deductible.

Can I claim home office expenses with an ABN?

You may be able to claim home office expenses if you genuinely use part of your home for business purposes. Deductible costs may include electricity, internet, phone, office equipment, software and stationery for the business-use portion. Only the business-use percentage can be claimed.

What is personal services income and how does it affect ABN workers?

Personal services income, or PSI, is income mainly produced from your personal skills or efforts rather than business structure or assets. PSI rules can affect which deductions are available and how income is treated. Contractors working mainly for one client on a labour-only basis are commonly affected. A registered tax agent can help assess your PSI position.
