Income tax in Australia is one of the first things you need to understand as soon as you set foot in the country. The system revolves around a personal number called the TFN, combined with a tax-free threshold and the Medicare levy. Understanding it correctly early on helps you avoid incorrect withholding and gives you more peace of mind.

What is a TFN and why it is mandatory
A TFN (Tax File Number) is a personal identification number issued by the Australian Taxation Office. It is a unique 9-digit sequence that stays with you throughout your working and tax-paying life in Australia, even if you change jobs or move states.
Almost every income-related transaction requires a TFN: receiving wages, receiving compulsory retirement contributions (superannuation), opening an interest-bearing savings account, receiving government benefits, and filing a year-end tax return. A TFN is not a work permit; it is simply a tool for the tax office to identify you.
The most important point for newcomers: if you provide your TFN to your employer as soon as you start a job, you are taxed according to the normal tax scale. Conversely, if you do not have a TFN after a certain period, your employer is required to withhold your income at the highest rate. This is why you should apply for a TFN as early as possible.
How to apply for a TFN as a new resident
Applying for a TFN is completely free. You do not need to pay any intermediary service, and you should be wary of parties that charge fees for “fast processing”.
For visa holders with work rights who are already in Australia, the most common way is to apply online through the Tax Office’s registration system. This system can cross-check your visa and foreign passport information against the immigration database, so hard-copy documents are usually not required.
You need to prepare some basic information before applying:
- Passport number and current visa type
- Residential address in Australia to receive mail
- Date of entry and personal information matching your immigration record
After submitting, the TFN is usually sent to your registered address within a few weeks. For this reason, you should apply early and make sure your mailing address is stable. You can refer to the application guide for new residents on the website of Australian Taxation Office.
Once you have your TFN, keep it as confidential as your banking password. Only provide it to your employer, bank, super fund and the tax office. Never post your TFN on social media or send it through an unsecured channel, as exposure of your TFN can lead to identity fraud.
Tax residency status and the tax-free threshold
One easily confused point is that tax residency status differs from immigration visa status. You may hold a temporary visa but still be considered a tax resident, or hold a permanent visa but be taxed as a foreign resident, depending on how long you have lived in Australia and your degree of connection to the country.
This distinction matters because tax residents are entitled to an annual tax-free income threshold. The portion of income below that threshold is not taxed; only the amount above it is subject to progressive tax rates. Those considered foreign residents for tax purposes usually do not get this tax-free threshold and are taxed from the first dollar at a higher starting rate.
When you start a job, your employer will give you a TFN declaration form. On this form there is a question asking whether you want to claim the tax-free threshold. As a general rule, you should only choose to claim the tax-free threshold at one job, usually the one that is your main source of income. If you claim it at multiple jobs at the same time, you are likely to be under-taxed and have to make up the difference at year-end.
How income tax in Australia is calculated
Income tax in Australia is applied on a progressive scale: the higher your income, the higher the tax rate on the portion above each threshold. This is a common mechanism in many developed countries, aimed at distributing the tax burden according to ability to contribute.
For most salaried employees, tax is withheld at the source through the PAYG (Pay As You Go) mechanism. This means that each pay period, your employer withholds a portion and pays it to the Tax Office on your behalf. At the end of the financial year, you reconcile the total amount withheld against the actual amount payable; if too much was withheld, you get a refund, and if too little was withheld, you must pay the difference.
Australia’s financial year does not coincide with the calendar year. The financial year starts on 1 July and ends on 30 June of the following year. This is an important milestone because all reporting obligations are calculated according to this cycle. Because tax rates and thresholds may change from year to year, you should look up the current rates at official sources rather than relying on figures heard from acquaintances.
The Medicare levy and its relation to tax
In addition to income tax, most tax residents in Australia also pay a charge called the Medicare levy, calculated as a percentage of taxable income. This levy helps fund the public Medicare health system and is calculated separately from income tax, although it is usually combined when settling at year-end.
Those considered foreign residents for tax purposes usually do not have to pay the Medicare levy, since they do not have full access to the public health system. People with very low income may also be exempt or have this levy reduced. To understand the associated health benefits in more detail, you can refer to our article on health insurance in Australia for new residents.
Some people with high income who do not have suitable private health insurance may also have to pay an additional surcharge. This is why many families consider buying private insurance alongside Medicare. The percentages and thresholds that apply may be adjusted each year, so check the current rates before calculating.
Year-end tax return obligations
After the financial year ends on 30 June, you usually have a period of time to file your tax return for the past year. The return summarizes all income, amounts already withheld, and eligible deductible expenses.
Newcomers are often surprised to learn that some expenses directly related to work can be deducted, reducing taxable income. Typical examples include:
- Cost of tools, mandatory uniforms, or equipment used for work
- Study and skills-development costs directly related to your current occupation
- A portion of work-related travel expenses during working hours
To claim these amounts, you need to keep receipts and documentation. Many people choose to lodge their own return through the Tax Office’s online system, while others hire a registered tax agent, especially when their financial situation is complex. The cost of hiring a legitimate tax agent is also a deductible expense.
Superannuation: retirement savings tied to income
When working in Australia, in addition to salary, your employer must also contribute an additional percentage into your compulsory retirement fund, called superannuation. This is money set aside for retirement, held in a separate fund in your name.
Although not a tax itself, super is closely tied to the income system and requires a TFN to function properly. If you do not provide your TFN to the fund, contributions may be taxed at a higher rate and it will be harder for you to track your account. Make sure you keep only one main super fund to avoid being charged multiple management fees in parallel.
Organizing your personal finances, from bank accounts to your retirement fund, should be done neatly from the start. You can read more in the article opening a bank account and managing finances in Australia for a fuller picture.
How tax residency is determined
Because tax residency status determines whether you are entitled to the tax-free threshold, understanding how it is determined is very important. The Tax Office does not just look at your visa type, but considers the overall circumstances of your life in Australia.
Factors commonly considered include:
- Whether you actually live in Australia or are only visiting briefly
- The length of time present in Australia within a financial year
- Whether you rent or buy a home, bring your family over, open accounts and settle in for the long term
- Intent to stay long-term, as shown through your job, contracts and daily life
A person who moves to Australia for long-term work, rents a home, brings their family and settles into a stable routine is likely to be considered a tax resident even while holding a temporary visa. Conversely, someone who comes for a short stay and then leaves may be taxed as a foreign resident. Since the line is sometimes unclear, if your circumstances are complex, you should seek advice to declare your status correctly from the start.
Declaring the wrong tax residency status can lead to overpaying or underpaying tax, requiring adjustment later. This is one of the points where newcomers most often get confused, so it is worth taking the time to understand it well.
Gross pay, net pay, and payslips
When starting a job in Australia, you should clearly distinguish between gross pay and net pay. Gross pay is the figure before tax is deducted, while net pay is the amount actually deposited into your account after tax has been withheld under the PAYG mechanism.
Each pay period, your employer usually provides a payslip that clearly states the relevant amounts. You should read these carefully and keep them, as they help with reconciliation at year-end. A complete payslip typically shows:
- Gross pay for the period and the year-to-date total since the start of the financial year
- The amount of tax withheld for the period
- The employer’s superannuation contribution
- Hours worked and the hourly rate, if applicable
The habit of checking payslips helps you catch errors early, such as not having your TFN applied and therefore being over-taxed, or your employer not paying enough super. Catching issues early is always easier to fix than letting them pile up until year-end.
The myGov system and linking with the Tax Office
Most transactions with the tax authority are now done online. Australians typically use an online government services account linked to the Tax Office to file returns, track refund status, and update personal information.
Once you have your TFN and are settled, you should set up an online account and link it to the tax authority. This helps you:
- Track income and amounts withheld as reported by your employer
- File your year-end tax return more conveniently, with much information pre-filled
- Check and manage super funds in your name
- Update your address and contact information promptly
For newcomers, getting familiar with this online system early will save a lot of time later on. Much of the year-end income information is already automatically reported by employers, so filing becomes simpler once you know how to use the system.
Notes to help newcomers avoid mistakes
Most tax troubles for newcomers stem from a few very basic mistakes:
- Not applying for a TFN early, resulting in wages being withheld at the highest rate
- Claiming the tax-free threshold at two jobs at the same time, resulting in under-taxation at year-end
- Confusing visa status with tax residency status
- Not keeping receipts for work expenses, missing out on legitimate deductions
- Keeping multiple super funds at once, incurring unnecessary management fees
If your family plans to move to Australia together, each working member needs their own TFN. Tax planning for the whole household should go hand in hand with overall settlement planning. You can also refer to the article bringing your family to Australia on a skilled visa to prepare in sync.
Summary
Australia’s tax system is fairly transparent but requires newcomers to be proactive: apply for a TFN early, understand your tax residency status correctly, claim the tax-free threshold at only one job, and keep records for settlement. Tax rates, thresholds and the Medicare levy may change from year to year, so depending on your goals and circumstances, you should check current information at official sources and consider consulting a tax accountant when needed.

Does applying for a TFN in Australia cost money?
No. Applying for a TFN is completely free through the Australian Taxation Office. You should be wary of parties charging fees for fast processing, as this is not a paid service.
I hold a temporary visa — am I entitled to the tax-free threshold?
You may be, if you meet the tax residency criteria. Tax residency status is based on how long you have lived in Australia and your degree of connection to the country, and does not entirely correspond to your visa type.
When does Australia’s financial year begin?
Australia’s financial year begins on 1 July and ends on 30 June of the following year, differing from the calendar year. All tax filing obligations are calculated according to this cycle.
Do foreign residents for tax purposes have to pay the Medicare levy?
Usually not, since they do not have full access to the public Medicare health system. Tax residents mostly have to pay this levy along with income tax.
Should I hire a tax agent to file my return?
It depends on the complexity. Simple cases can be filed online yourself. If you have multiple income sources or deductions, hiring a registered tax agent helps avoid mistakes, and this cost is also deductible.
