Self-Employed Tax Rates In Australia: What Sole Traders Must Know

Being your own boss can be incredibly rewarding - you set your own hours, build your brand, and choose the work you say yes to. But with that freedom comes the responsibility to manage your own tax and compliance.

If you’re a sole trader, understanding how self‑employed tax works in Australia will help you set money aside, avoid surprises at tax time, and keep your business on track.

In this guide, we’ll explain how sole traders are taxed (and how this differs from employees), outline current tax rate settings and the Medicare Levy, walk through a simple step‑by‑step for calculating your tax, and cover the other obligations that commonly apply to self‑employed people.

Important: The information below is general information, not financial or tax advice. Tax rules change and everyone’s situation is different - speak with a registered tax agent for advice tailored to you.

What Does “Self‑Employed” Mean For Sole Traders?

In Australia, “self‑employed” usually means you run your own business rather than being engaged as an employee. Many people do this as a sole trader - you operate under your own name (or a registered business name), control decisions, and you’re personally responsible for the business’ tax and debts.

You might freelance, consult, sell products online, or provide a trade or professional service. If you’re issuing invoices and getting paid for your own work under an Australian Business Number (ABN), you’re generally working as a sole trader.

If you’re unsure whether you’re operating a business or doing a hobby, it’s worth reading what defines a business activity in Australia. And if you’ve been asked to work “under an ABN” and want to be sure you’re set up correctly, this overview of working under an ABN is a good starting point.

There’s also a key distinction between an employee and an independent contractor. If you’re not sure which applies, it’s wise to get employee/contractor advice before you commit - the category affects your tax, super and legal obligations.

How Are Sole Traders Taxed In Australia?

Sole traders don’t pay a separate “business tax rate.” Instead, your business profit (your income minus allowable expenses) is added to your other personal income for the year and taxed at individual marginal tax rates.

There’s also a 2% Medicare Levy for most Australians (subject to low-income thresholds and exemptions). In short: you calculate your business profit, add it to any other income (salary from a job, bank interest, rental income, etc.), then apply the individual rates for that financial year.

PAYG Withholding vs PAYG Instalments

This is a common source of confusion:

• PAYG withholding is what employers do - they withhold tax from an employee’s wages and send it to the ATO.
• PAYG instalments are different - if you’re a sole trader, the ATO may ask you to pay tax in advance during the year in instalments based on your last return or current estimates. These instalments go towards your final tax bill.

As a sole trader, you don’t have PAYG withholding taken out of your business income. Instead, you may be put into the PAYG instalments system so you’re pre‑paying some of your expected tax across the year.

Current Self‑Employed Tax Rates (And Medicare Levy)

For sole traders, the “self‑employed tax rate” is simply the resident individual tax scale for the year in question. These brackets are set by the government and can change from time to time.

• 2023–24: Sole traders were taxed under the standard resident individual rates for that year, plus the Medicare Levy for most taxpayers.
• From 1 July 2024 (2024–25): New individual tax rates apply following legislated changes. The tax‑free threshold remains, and marginal rates and thresholds have been adjusted. The Medicare Levy (2%) continues to apply to most taxpayers.

Always check the ATO’s current individual rates before you calculate or set aside money for tax - especially if you’re comparing 2023–24 to 2024–25 and later years. A small change in thresholds can shift your final tax by more than you expect.

Also keep in mind the Medicare Levy Surcharge (different to the 2% Levy) can apply if your income is above certain thresholds and you don’t have appropriate private hospital cover.

Step‑By‑Step: How To Work Out Your Sole Trader Tax

Here’s a practical way to approach your tax as a sole trader. Many people do this with a spreadsheet and accounting software, or with help from a tax agent.

1. Total up your business income. Add all the amounts you’ve invoiced and been paid for your work for the financial year.
2. Subtract allowable business expenses. You’re taxed on profit, not sales. Deduct eligible costs directly related to running the business (for example: tools and equipment, insurance, software, marketing, professional fees, bank fees, and business‑related travel). Keep invoices and records to substantiate each claim.
3. Calculate your net profit (or loss). Income minus expenses equals your business profit for the year. If you operated at a loss, special rules apply to whether you can offset that loss against other income - get advice before relying on it.
4. Add other personal income. Add your wage/salary from any job, bank interest, dividends, rental income, etc., to arrive at your total taxable income.
5. Apply the relevant individual rates for that year. Use the resident individual marginal rates for the correct financial year (and include the Medicare Levy if it applies to you).
6. Factor in offsets and credits. Depending on your circumstances, you may be eligible for tax offsets that reduce your tax payable.
7. Consider PAYG instalments. If the ATO has put you into PAYG instalments, your instalments through the year will be credited against your final tax when you lodge. If cash flow is tight or your income has changed, you can often vary instalments (talk to your tax agent before you do).

Tip: Set up a separate savings account and move a percentage of each payment you receive into it for tax and GST. That way, the money is ready when your BAS or tax bill falls due.

What About Superannuation And Paying Yourself?

Sole traders don’t pay themselves a wage from their business like an employee - you typically draw funds from the business bank account as the owner. For a clear overview of options and pitfalls, see how to legally pay yourself as a business owner. While you’re not required to pay yourself super by law as a sole trader, voluntary contributions can be a smart way to save for retirement (and some contributions may be deductible - ask your tax agent).

Other Taxes And Obligations To Watch

Depending on your turnover, industry and whether you hire help, other obligations can apply alongside your income tax.

GST (Goods And Services Tax)

• You must register for GST if your GST turnover is $75,000 or more in a 12‑month period. Some industries (like ride‑sourcing) have special rules, so check the ATO if you’re unsure.
• Once registered, you add 10% GST to most taxable sales, lodge Business Activity Statements (BAS) monthly or quarterly, and claim GST credits for eligible business purchases.

If you’re new to BAS, good recordkeeping will make lodgements far less stressful. Many sole traders use accounting software so invoices, expenses and GST are tracked automatically.

ABN And Business Name

If you’re running an enterprise, you’ll generally need an ABN. If you trade under a name that’s not your personal name, you’ll also need to register a business name. Not sure whether you need an ABN? This overview on running a business without an ABN explains the risks of invoicing without one.

Hiring People

If you bring on staff, you’ll have Fair Work obligations, superannuation and (if relevant) payroll tax and workers compensation considerations. If you engage help as contractors instead, make sure the arrangement is genuine contracting - incorrect classification can be costly. When in doubt, get employee/contractor advice before you hire.

Taking Payments And Terms

Clear payment terms help cash flow and reduce disputes. If you’re taking direct debits or recurring card payments, make sure your processes align with direct debit laws in Australia.

Smart Compliance For Sole Traders: Records, Registrations And Contracts

Your legal and admin setup doesn’t have to be complicated. Focus on getting the core elements right from day one so you can spend more time on your clients and growth.

Keep Strong Records

• Track income and expenses (including receipts and invoices) for at least five years.
• Use a business bank account to keep personal and business money separate.
• Diary BAS and tax lodgement due dates to avoid penalties and interest.

Register What You Need

• ABN for your enterprise and GST if you hit the threshold.
• Business name if you’re trading under a name that isn’t your own.

Protect Your Business With The Right Documents

• Customer Contract: Sets out your scope, deliverables, fees, payment terms, IP ownership, cancellations and liability limits. This is essential for services and project work.
• Privacy Policy: Required if you collect personal information and best practice for any website or online form. It should explain what you collect, why, and how you store and use it.
• Website Terms and Conditions: The rules for using your site, protecting your IP and setting limits on your liability for information published online.

These documents reduce risk, prevent misunderstandings and help you get paid. They’re most effective when tailored to your actual services, pricing model and risk profile.

Know When To Get Help

If you’re unsure whether you’re “in business”, planning to scale, or considering a new income stream, getting advice early can save you time and money. This includes legal guidance on your contracts and compliance, and tax guidance from a registered tax agent on the best way to structure your finances and claim deductions.

Common Questions From Sole Traders

Do part‑time or side‑hustle earnings get taxed differently?

No. All your income for the year is added together and taxed at your marginal rate. If you have both a job and a sole trader business, keep good records for each so your return is accurate.

What deductions can I claim?

Generally, you can claim expenses that are directly connected to earning your business income (for example, professional fees, software, marketing and a reasonable portion of home office running costs if you work from home). Keep receipts and apportion shared expenses between private and business use.

What happens if I underpay my tax?

The ATO can apply interest and penalties. If you can’t pay on time, contact the ATO early to set up a payment plan. Staying on top of BAS and keeping money aside each month helps you avoid a crunch at year‑end.

Do I need a company?

Not to start as a sole trader. Many people begin as a sole trader for simplicity, then consider a company later for liability and growth reasons. If you’re weighing up structures, think about risk, profits, and long‑term plans - and get tailored advice if you’re unsure.

Key Takeaways

• Sole traders don’t have a separate “self‑employed tax rate” - your business profit is added to your other income and taxed at individual marginal rates, plus the Medicare Levy for most taxpayers.
• Know the difference between PAYG withholding (for employees) and PAYG instalments (for sole traders pre‑paying tax). Instalments are credited against your final bill when you lodge.
• Tax brackets can change from year to year (including changes from 1 July 2024), so always apply the correct rates for the financial year you’re lodging.
• Register for GST if your turnover reaches $75,000, keep strong records, and diarise BAS and tax due dates to avoid penalties.
• Protect your business with clear client terms, a Privacy Policy and Website Terms - these documents set expectations, reduce disputes and support healthy cash flow.
• If you’re uncertain about deductions, GST, or whether you’re a contractor vs employee, get professional advice early - it’s far cheaper than fixing mistakes later.
