Tax Basics for Immigrants in Australia

Filing your first tax return in Australia can feel overwhelming. The terminology is different, the system is different, and nobody warns you about the things that trip up newcomers. Many immigrants either overpay because they do not claim legitimate deductions, or they get into trouble because they did not understand their obligations.

This guide walks you through the Australian tax system step by step — from getting your Tax File Number to lodging your first return.

Getting Your Tax File Number (TFN)

Your Tax File Number is your unique identifier in the Australian tax system. You need it to:

• Start any job (your employer needs it to pay you correctly)
• Open a bank account (without a TFN, the bank withholds tax at the highest rate on your interest)
• Lodge your tax return
• Access government services like Centrelink or Medicare

You can apply for a TFN through the ATO website. If you are on a visa, you can apply online — it is free and takes about 28 days. Never pay anyone to get you a TFN. There are scam websites that charge for this free service.

The Australian Financial Year

The Australian financial year runs from 1 July to 30 June. This catches many immigrants off guard because most countries use the calendar year (January to December).

Your tax return for the 2024-25 financial year covers income earned from 1 July 2024 to 30 June 2025. You must lodge it by 31 October 2025 if you are doing it yourself, or you get an extended deadline if you use a registered tax agent.

Tax Brackets: How Much Tax Do You Pay?

Australia uses a progressive tax system. This means you do not pay the same rate on all your income — you pay increasing rates as your income increases. Here are the current tax brackets for 2024-25 as per the ATO:

Important: These rates are for Australian residents for tax purposes. If you are a non-resident (which has a specific tax definition — it is not the same as your visa status), you do not get the tax-free threshold and you pay higher rates from dollar one.

On top of income tax, most people pay the Medicare levy of 2% of their taxable income. This funds Australia's public health system.

Tax Residency: The Trap Nobody Warns You About

Your tax residency is not the same as your visa status. You can be on a temporary visa and still be considered a tax resident. The ATO looks at factors like:

• Where you live (your "domicile")
• How long you have been in Australia
• Whether your family is here
• Your intention to stay

Being a tax resident is usually better because you get the tax-free threshold ($18,200) and lower rates. If you are classified as a non-resident for tax purposes, you pay tax from the first dollar and at higher rates.

If you are unsure, use the ATO's residency tool or speak with a tax agent who understands immigration scenarios.

Common Deductions Immigrants Miss

A tax deduction reduces your taxable income, which reduces the amount of tax you pay. Many immigrants do not claim deductions they are entitled to because they do not know they exist.

Here are deductions you should know about:

Work-Related Deductions

• Home office expenses: If you work from home, you can claim electricity, internet, phone, and office furniture. The ATO offers a fixed rate of 67 cents per hour for the 2024-25 year.
• Work-related travel: Travel between two workplaces (not home to work) is deductible. If you travel for work to client sites, that counts.
• Uniforms and protective clothing: Occupation-specific clothing, sun protection, and safety gear.
• Professional development: Courses, workshops, and conferences related to your current job. Note: courses for a NEW career are generally not deductible (but there are exceptions — see our education tax deductions guide).
• Tools and equipment: Laptops, software, and tools you use for work. Items under $300 can be claimed in full; more expensive items are depreciated.
• Union fees and professional memberships: If you belong to a professional body relevant to your work.

Other Deductions

• Donations: Gifts of $2 or more to registered charities (called Deductible Gift Recipients or DGRs).
• Income protection insurance: Premiums for policies held outside super.
• Tax agent fees: If you pay a tax agent to prepare your return, the fee is deductible the following year.

What You Cannot Claim

• Travel from home to work (this is considered private, not work-related)
• Normal clothing (even if you wear it to work)
• Childcare costs
• Rent or mortgage for your home (unless you are running a business from home)

How to Lodge Your Tax Return

You have three options:

1. myTax (free): The ATO's online tool through myGov. Most salary and wage income is pre-filled by August. It is straightforward for simple returns.
2. Tax agent: A registered professional who prepares and lodges your return. Costs $100-$400 but gives you access to their expertise and extended lodgement deadlines.
3. Paper form: Still exists but almost nobody uses it.

For your first year in Australia, consider using a tax agent who understands immigrant tax situations. They can help you navigate residency questions, foreign income declarations, and deductions you might not know about.

Foreign Income: What You Must Declare

If you are an Australian tax resident, you must declare your worldwide income. This includes:

• Rental income from property overseas
• Interest from bank accounts in your home country
• Dividends from shares in overseas companies
• Any freelance or business income earned overseas

Australia has Double Taxation Agreements (DTAs) with many countries, which means you generally will not pay tax twice on the same income. You may receive a foreign income tax offset for tax already paid overseas. The ATO has a list of countries with DTAs.

Important: Not declaring foreign income is a serious offence. The ATO has data-sharing agreements with tax authorities in many countries. They will find out.

The Medicare Levy and Medicare Levy Surcharge

The Medicare levy is 2% of your taxable income and funds Australia's public health system. Most taxpayers pay it automatically.

If you earn over $93,000 as a single person and do NOT have private hospital insurance, you also pay the Medicare Levy Surcharge — an additional 1-1.5% of your income. This is the government's way of encouraging higher earners to take out private health insurance and reduce pressure on the public system. Details are on the ATO website.

Do I need to lodge a tax return even if I earned very little?

Yes, in most cases you should still lodge. Even if you earned below the tax-free threshold, lodging a return ensures you get back any tax that was withheld from your pay. It also keeps your ATO record clean. If you truly had zero Australian income, you may not need to lodge, but it is safer to check with the ATO.

What happens if I lodge late?

If you miss the 31 October deadline and owe money, the ATO can charge a Failure to Lodge (FTL) penalty of $313 for each 28-day period you are late, up to a maximum of five periods ($1,565). If you are owed a refund, there is technically no penalty — but it is best to lodge on time regardless.

Can I claim the cost of my migration or visa application?

No. Visa application fees, migration agent costs, and skills assessment fees are considered private expenses and are not tax-deductible.

Action Steps for Your First Tax Year

1. Get your TFN as soon as you arrive (it is free — do not pay anyone)
2. Give your TFN to your employer on your first day using the Tax File Number Declaration form
3. Give your TFN to your bank to avoid excess withholding on interest
4. Keep receipts for all work-related expenses throughout the year
5. Check your tax residency status — it affects everything
6. Declare all worldwide income including foreign bank interest
7. Lodge by 31 October or engage a tax agent for an extended deadline
8. Review your PAYG summary (now called the Income Statement) in myGov after 30 June

Getting your tax right from year one saves you headaches, penalties, and money. The Australian tax system is actually quite fair once you understand it — and the deductions available to you can put real money back in your pocket.
