Common finance and tax mistakes new arrivals to Australia make

Many of the financial mistakes new arrivals make in Australia happen not for lack of intelligence — but because the system differs from what is familiar. This list is not meant to judge, but so you do not have to learn each one the hard way.

1. Not lodging a tax return because you think there’s nothing to refund

Many people think: “I have no special deductions, so why lodge a return?” This is wrong on two points.

First, if you start working partway through the financial year, tax is withheld as if you were working all 12 months — but in reality you worked less, so you are often owed a refund.

Second, if you did not give your employer your TFN in time, tax is withheld at the highest rate — and lodging a return is the only way to get the excess back.

Not lodging a return when you are required to can also lead to penalties later.

2. Not keeping track of your super

Across different jobs, many people end up with three, four, even five small super accounts at different funds. Each account charges annual maintenance fees — money that quietly disappears over the years.

Checking and consolidating your super accounts through myGov is simple but has real value. For more, see the related guide on superannuation explained simply.

3. Not knowing whether you are a tax resident

Tax residency affects the tax rate you pay and the income you must declare. New arrivals often assume they are a “tax resident” because they live in Australia — but the determination is not automatic and not that simple.

Some people remain a tax resident of their home country for a period; some are a tax resident from the day they set foot in Australia. Getting it wrong can lead to under-declaring foreign income.

See the related guide on what tax residency in Australia means.

4. Confusing the Medicare levy with Medicare

Medicare is the public health system — those who are eligible can use it for doctor visits, public hospitals, and some other services. The Medicare levy is a charge on income tax to help fund this system.

A common mix-up: not being eligible for Medicare (on a temporary visa) but not applying for a Medicare levy exemption — so still paying the levy despite not being able to use the service.

See the related guide on the Medicare levy and who has to pay it.

5. Not building credit history from the start

Credit history matters more than many people realise when they first arrive — not just for bank loans, but also for renting a home and some financial services. New arrivals start with an empty record and have no way to “import” their credit history from their home country.

Building credit history is a long-term process — the earlier you start, the better off you are later.

See the related guide on why your credit history matters and why new arrivals should care.

6. Confusing gross pay with take-home pay

In Australia, wages are usually negotiated and advertised as gross — that is, before tax and super are deducted. Many new arrivals are surprised when their actual take-home (net) pay is significantly lower than the figure they negotiated.

The difference comes from: income tax, the Medicare levy, and how super is calculated (if the offer is a “total package including super” rather than “base salary plus super”). When comparing pay offers, ask clearly about the structure before you accept.

7. Not keeping receipts for work expenses

If you buy equipment, books, or work-related training with your own money, you may be able to deduct it when you lodge your tax return — but you need evidence. Many people forget to keep receipts during the year and miss the deduction when tax time comes.

A simple habit: photograph receipts as soon as you buy something, and save them in a dedicated folder. Do not rely on paper receipts, which fade and are easily lost.

8. Sharing your TFN too freely

A TFN is sensitive information, and not everyone who asks for it has a legitimate reason. A landlord, a recruiter during the interview stage, or an acquaintance offering to “help with your tax return” usually has no valid reason to know your TFN.

See the related guide on what the TFN is and why to understand it before working in Australia.
