Tax Tips For Your Side Hustle: How To Handle Side Hustle Taxes In Australia

A side hustle can put extra money in your pocket, but it also brings tax responsibilities that many people overlook. We regularly see locals across Mildura earning income from freelancing, ride-share driving, online sales, or weekend contracting, only to realise at tax time that the ATO expects its share. The good news is that side hustle taxes are manageable when you understand the rules around reporting side income, claiming legitimate deductions, and planning for PAYG instalments or GST. With the right structure in place from the start, you can grow your income without stepping into a tax headache.

Hobby Or Business? Why This Decision Changes Your Tax Obligations

Your first step is simple: decide whether your activity is a hobby or a business. This decision affects everything — from ABN registration to claiming business expenses deductions.

We have helped hundreds of small operators across regional Victoria with this exact question. Many people assume small income equals hobby. That is not how the ATO sees it.

The ATO’s Business Indicators

The ATO looks at your intention and behaviour, not just your income.

You are likely running a business if:

• You intend to make a profit
• You operate in a regular and repeated way
• You advertise or promote your services
• You keep records and issue invoices
• You behave in a business-like manner

For example:

Sarah in Mildura sells handmade candles at local markets. She tracks costs, prices for profit, advertises on Instagram, and attends markets monthly. Even if she earns AUD 8,000 a year, this is a business.

Now compare that with:

Mark restores old motorbikes for fun. He occasionally sells one to fund his next project. He does not advertise or plan for profit. That is likely a hobby.

The difference matters.

Hobby vs Business: Quick Comparison Table

Issue	Hobby	Business (Sole Trader)
Report income?	No	Yes
Claim deductions?	No	Yes
Need an ABN?	No	Usually yes
GST registration?	No	If turnover exceeds AUD 75,000
BAS lodgement?	No	If registered for GST

If you run a business, you must report side income in your tax return. You can then claim freelance tax deductions and small business tax tips that reduce your taxable income.

If it walks like a duck and quacks like a duck, the ATO will call it a business.

Sole Trader Tax Australia: Do You Need An ABN?

Most side hustles operate as sole traders. This is the simplest business structure in Australia.

You and the business are legally the same entity. Income goes into your personal tax return. You pay tax at individual marginal rates.

When You Need An ABN

You generally need an Australian Business Number (ABN) if you:

• Carry on an enterprise
• Issue invoices
• Work as a contractor
• Want to avoid PAYG withholding at 47%

Without an ABN, businesses paying you may withhold tax at the top marginal rate. That can hurt your cash flow quickly.

We recently assisted a local photographer who forgot to provide an ABN to a winery. The winery withheld nearly half the payment. We fixed it at tax time, but it created unnecessary stress.

Registering for an ABN is free through the Australian Business Register. It takes about 15 minutes online.

Reporting Side Income: What Must You Declare?

Many people assume income is only taxable if they receive a payment summary. That is not correct.

You must declare:

• Cash payments
• Bank transfers
• Digital platform payments (Uber, Airtasker, Fiverr, Etsy)
• Cryptocurrency payments
• Overseas income

The ATO uses data matching. Ride-share, food delivery, and marketplace platforms report income directly.

If you earn AUD 3,000 from design work on weekends, that amount must be included in your return. There is no minimum threshold where income becomes “tax-free” simply because it is small.

Separating Personal And Business Finances: Why It Matters

Mixing personal and business money creates confusion. It also increases the risk of missed deductions.

We always recommend opening:

• A separate bank account
• A separate debit card
• A separate savings account for tax

Even if you only earn AUD 500 per month, separation keeps things clean.

Here is a simple cash flow structure we suggest:

Account	Purpose
Business Account	All income deposited here
Expense Card	Pay business costs only
Tax Savings Account	Transfer 25–30% of profit
Personal Account	Owner drawings only

This system prevents the “tax bill shock” we see every year in July.

Record Keeping For Taxes: The ATO’s Five-Year Rule

In Australia, you must keep business records for five years.

This includes:

• Invoices issued
• Receipts for expenses
• Bank statements
• Logbooks for vehicle claims
• Home office records
• BAS statements

Digital copies are acceptable. We often see clients photograph receipts using apps like Xero or MYOB.

If the ATO reviews your return, documentation is your safety net.

As we tell clients, paperwork may feel dull, but it keeps you out of hot water.

Contractor vs Employee Tax: Know The Difference

Many side hustlers work as contractors. Others mistakenly believe they are contractors when legally, they are employees.

This distinction affects:

• PAYG withholding
• Super contributions
• Workers compensation
• Tax deductions

You Are Likely A Contractor If:

• You control how and when work is done
• You invoice for services
• You provide your own tools
• You carry business risk

You Are Likely An Employee If:

• The employer controls your hours
• You receive leave entitlements
• You are paid wages with PAYG withheld

Misclassification causes problems. We have seen cases where people missed super contributions because they assumed contractor status.

If unsure, seek advice early.

GST For Small Business: Do You Need To Register?

You must register for GST if:

• Your turnover exceeds AUD 75,000 per year
• You provide ride-sourcing services (regardless of income)

Turnover means gross income before expenses.

If registered for GST, you must:

• Charge 10% GST on taxable supplies
• Lodge BAS statements (usually quarterly)
• Claim GST credits on business purchases

Example: Ride-Share Driver In Mildura

Tom drives Uber part-time. He earns AUD 22,000 annually. Even though he is under the AUD 75,000 threshold, ride-sourcing rules require GST registration.

Tom must:

• Add GST to fares
• Lodge quarterly BAS
• Claim GST credits on fuel and vehicle expenses

Many new drivers do not realise this. The ATO does.

Freelance Tax Deductions: What You Can Legitimately Claim

Claiming deductions reduces your taxable income. That means you pay tax on profit, not turnover.

Many people leave money on the table because they do not understand what qualifies as a business expense deduction. The rule is simple:

The expense must be directly related to earning your income.

If it helps you generate side hustle income, it is usually deductible.

We often tell clients, “If you need it to do the job, and you paid for it yourself, we should be looking at it.”

Common Tax Write-Offs for Freelancers And Gig Workers

Here are deductions we regularly claim for clients across Mildura and regional Victoria:

Equipment and Tools

• Laptops and computers
• Cameras and lighting equipment
• Power tools
• Mobile phones
• Printers and scanners

If the asset costs less than the instant asset write-off threshold (check current ATO limits each year), you may claim the full amount immediately. Otherwise, you depreciate it over its effective life.

Software and Subscriptions

• Xero, MYOB, QuickBooks
• Canva Pro
• Adobe Creative Cloud
• Industry-specific apps

Professional Services

• Accountant fees
• Bookkeeper costs
• Legal advice
• Business insurance

Marketing

• Website hosting
• Domain registration
• Facebook and Google ads
• Business cards

Training and Education

• Courses related to your current business
• Webinars
• Industry conferences

If the course opens a new career path, it is not deductible. If it improves your existing income stream, it usually is.

Home Office Deduction: Working From Home The Right Way

Many side hustles operate from home. In Mildura, we see spare bedrooms converted into beauty rooms, sheds turned into workshops, and kitchen tables doubling as office desks.

The ATO allows a home office deduction, but the method matters.

Fixed Rate Method (Current ATO Rate)

For the 2024–25 income year, the fixed rate is 70 cents per hour worked from home.

This rate covers:

• Electricity and gas
• Internet
• Phone usage
• Stationery

You must keep:

• A record of hours worked
• Evidence of at least one bill per expense category

If you work 15 hours per week for 48 weeks:

15 × 48 = 720 hours
720 × 0.70 = AUD 504 deduction

It adds up.

Actual Cost Method

This method requires detailed calculations.

You calculate:

• Percentage of floor space used
• Percentage of time used for business
• Actual utility costs

This method may suit someone running a dedicated studio or consulting room at home.

We usually compare both methods and choose the higher deduction.

Home Office Checklist

• Do you have a dedicated workspace?
• Do you keep a diary of hours worked?
• Do you retain electricity and internet bills?
• Do you avoid claiming private usage?

If the answer is yes, you are on the right track.

Vehicle Expense Deduction: Cents Per Kilometre Or Logbook?

Vehicle claims are heavily reviewed by the ATO. Good records protect you.

You can claim business travel such as:

• Visiting clients
• Picking up supplies
• Travelling between job sites

You cannot claim:

• Travel from home to a regular workplace
• Private errands

Method 1: Cents Per Kilometre

For the 2025–26 financial year, the rate is 88 cents per kilometre, up to 5,000 km.

Maximum claim:
5,000 km × 0.88 = AUD 4,400

You must:

• Be able to explain how you calculated kilometres
  
  
• Show that the travel was business-related

This method suits people with lower business travel.

Method 2: Logbook Method

You:

• Keep a 12-week logbook
• Record total kilometres
• Determine the business use percentage
• Apply the percentage to all vehicle expenses

Expenses include:

• Fuel
• Insurance
• Registration
• Repairs
• Depreciation

Example:

Emma is a mobile hairdresser in Mildura. Her logbook shows 65% business use.

Her annual vehicle costs total AUD 12,000.

12,000 × 65% = AUD 7,800 deduction.

The logbook method often produces higher deductions for mobile operators.

Internet And Phone Deductions

If you use your phone or internet for business, you can claim the business portion.

You must calculate:

• Total usage
• Business percentage

Example:

Monthly mobile bill = AUD 90
Business use = 40%
Annual deduction:
90 × 12 × 40% = AUD 432

Small amounts add up over time.

Claiming Equipment Expenses: Depreciation Explained Simply

If equipment costs more than the instant write-off threshold, you must depreciate it.

Depreciation spreads the deduction over several years.

Example:

Laptop cost = AUD 3,000
Effective life = 3 years

You claim part each year.

We calculate depreciation using ATO schedules. It ensures accuracy and avoids overclaiming.

Quarterly Estimated Taxes And PAYG Instalments

When you earn salary income, tax is withheld automatically. Side hustlers do not have that luxury.

If your side business makes a profit, you may need to pay tax during the year.

In Australia, this usually happens through PAYG instalments.

When PAYG Instalments Apply

The ATO may enrol you if:

• You earn over a certain amount of business income
• You have a tax bill above the threshold

You then pay tax quarterly.

BAS Lodgement: What You Need To Know

If you register for GST, you must lodge a Business Activity Statement (BAS).

Your BAS reports:

• GST collected
• GST paid
• PAYG instalments (if applicable)

Most small businesses lodge quarterly.

Missing BAS deadlines leads to fines. Even if you owe nothing, you must lodge.

We often handle BAS for clients because it reduces errors and stress.

Super Contributions For Self Employed

Employees receive compulsory super. Sole traders do not.

If you do not contribute voluntarily, you may fall behind.

You can:

• Make personal deductible super contributions
• Claim a tax deduction
• Reduce taxable income

Example:

Side hustle profit = AUD 30,000
Super contribution = AUD 5,000

Your taxable income reduces by AUD 5,000.

Super is not just retirement planning. It is also a tax planning tool.

Tax Planning For Freelancers: Avoid The July Shock

Every year, we see the same pattern. People focus on income. They forget tax.

Then July arrives.

The key is planning early.

Simple Tax Planning Strategy

1. Estimate annual profit
2. Set aside 25–30% for tax
3. Track expenses monthly
4. Review profit before 30 June
5. Consider super contributions before year-end

Profit And Loss Statement Snapshot

Item	Amount (AUD)
Income	40,000
Expenses	15,000
Net Profit	25,000

Tax applies to AUD 25,000, not 40,000.

Clear numbers create confidence.

Maximising Tax Refunds Without Risk

Maximising tax refunds does not mean stretching claims.

It means:

• Claiming every legitimate deduction
• Keeping clean records
• Structuring income correctly
• Planning before 30 June

The ATO data-matches aggressively. Honest claims backed by records keep you safe.

A side hustle can strengthen your cash flow and open new doors. Across Mildura, we see weekend gigs grow into steady income streams because the foundations were set early. The difference is not luck. It is structured. Register correctly, report all side income, separate your finances, and track your business expenses deductions carefully. Small habits done consistently keep you out of trouble.

Side hustle taxes do not need to feel overwhelming. When you monitor your profit, plan for PAYG instalments, watch your GST threshold, and keep clear records, tax becomes part of the routine rather than a shock in July. If you are unsure about your position, getting advice early often costs less than fixing mistakes later.
