Your ATO Tax Checklist for Foreign Workers

Working in Australia as a foreign national means you have specific tax obligations to the Australian Taxation Office (ATO). Getting these right from day one protects you from penalties, ensures you don't pay more tax than you owe, and keeps your visa status secure. This checklist covers what you must do:

  1. Determine your tax residency status
  2. Apply for a Tax File Number (TFN)
  3. Declare all income to your employer
  4. Report foreign income if you earn it
  5. Lodge a tax return each financial year
  6. Claim deductions and offsets you're entitled to

Each of these steps has real consequences if missed. Let's work through them one by one.

Determine Your Tax Residency Status

The first and most important step is understanding whether you are an Australian resident for tax purposes. This is not the same as holding a permanent residency visa. Tax residency is determined by the ATO based on where you live and work.

You are considered an Australian resident for tax purposes if you meet any of these tests:

  • You have been in Australia for more than 183 days in the financial year (1 July to 30 June)
  • You have a permanent place of abode in Australia and intend to reside there
  • You are an Australian citizen or permanent resident (regardless of where you live)
  • You work in Australia on a long-term contract (typically two years or more)

If you are a tax resident, you pay tax on your worldwide income at the standard Australian tax rates. The first $18,200 of annual income is tax-free. Income above that is taxed at progressive rates: 19% on income between $18,201 and $45,000, 32.5% on income between $45,001 and $120,000, 37% on income between $120,001 and $180,000, and 45% on income above $180,000.

If you are not a tax resident (for example, you are on a short-term working holiday visa and have been in Australia for fewer than 183 days), you pay tax only on Australian-sourced income. You do not get the tax-free threshold. Instead, tax is withheld at 45% on your employment income unless you have a Tax File Number.

Contact the ATO directly if you are unsure. Call 13 28 61 (within Australia) or visit ato.gov.au to use their residency assessment tool.

Apply for a Tax File Number (TFN)

Every foreign worker in Australia must have a Tax File Number. This is a unique nine-digit number that the ATO uses to track your income, tax payments, and superannuation contributions.

Without a TFN, your employer is required by law to withhold tax at the highest marginal rate. For tax residents, this is 47%. For foreign residents, it is 45%. This means you lose nearly half your pay before you even see it. Getting a TFN immediately prevents this.

You can apply for a TFN in three ways:

  1. Online: Visit the ATO website at ato.gov.au/individuals/tax-file-number/ and complete the online application. You will need your passport and visa details. Most applications are processed within two weeks.
  2. In person: Visit an ATO office or a post office that offers ATO services. Bring your passport and visa. You will receive a TFN on the spot or within a few days.
  3. By mail: Download the TFN application form from the ATO website, print it, sign it, and mail it with a certified copy of your passport and visa to your nearest ATO office. This takes 4 to 6 weeks.

Once you have your TFN, give it to your employer immediately. Your employer must have your TFN before they can adjust your tax withholding. If you start work without providing a TFN, ask your payroll team to update their records as soon as you receive it.

Keep your TFN safe. Do not share it with anyone except your employer, your bank, and the ATO. If your TFN is lost or stolen, contact the ATO immediately on 13 28 61.

Declare All Income to Your Employer

Once you have a TFN, you must declare it to your employer. Your employer uses your TFN to calculate the correct amount of tax to withhold from your pay each week or fortnight.

When you start a new job, your employer will ask you to complete a Tax File Number Declaration form (also called a TFN declaration). This form tells your employer your TFN and confirms your tax residency status. Do not leave this form blank or provide incorrect information. If you do, your employer must withhold tax at the highest rate.

If your tax residency status changes during the year (for example, you reach 183 days in Australia and become a tax resident), tell your employer immediately. Provide an updated TFN declaration so your tax withholding is adjusted correctly.

Your employer must withhold tax from your pay each pay period. The amount depends on your tax residency status and the tax-free threshold claim you have made. If you have multiple jobs, only one employer can apply the tax-free threshold. Tell your primary employer (the one paying you the most) that you claim the threshold. Other employers must withhold tax at a higher rate.

Keep payslips from every job. These show how much tax has been withheld. You will need them when you lodge your tax return.

Report Foreign Income If You Earn It

If you earn income outside Australia while working here, you must declare it on your tax return. This includes income from rental property, freelance work, investments, or employment in another country.

As a tax resident, you pay tax on your worldwide income. This means Australian tax applies to foreign income as well. However, if you have already paid tax on that foreign income in the country where you earned it, you may be able to claim a foreign income tax offset. This offset reduces the Australian tax you owe by the amount of tax you paid overseas.

To claim a foreign income tax offset, you need to provide evidence of the tax you paid. Keep receipts, tax certificates, or official letters from the foreign tax authority. When you lodge your tax return, declare the gross foreign income and the tax you paid. The ATO will calculate the offset for you.

If you are working in Australia on the Pacific Australia Labour Mobility (PALM) scheme, you must declare that employment income on your tax return just like any other Australian income. The same tax rules apply.

Lodge a Tax Return Each Financial Year

You must lodge a tax return for every financial year you work in Australia, even if you have only worked for part of the year. The financial year runs from 1 July to 30 June. Tax returns are due by 31 October each year.

You can lodge your tax return online through the ATO's myTax portal, by mail, or through a registered tax agent. Most foreign workers find myTax the easiest option. You will need your TFN and your payslips.

When you lodge your return, declare all income you earned during the financial year. Include employment income, foreign income, and any other income. Claim any deductions you are entitled to, such as work-related expenses, professional fees, or home office costs. If you have paid tax on foreign income, claim the foreign income tax offset.

The ATO typically processes tax returns within 2 to 4 weeks. If you are entitled to a tax refund, it will be paid into your nominated bank account. If you owe tax, you will receive a bill. Pay any tax owing by the due date to avoid penalties and interest.

Claim Deductions and Offsets You Are Entitled To

As a foreign worker, you can claim deductions for work-related expenses. These reduce your taxable income and lower the tax you owe. Common deductions include:

  • Uniforms and protective clothing (if you must wear them for work and launder them yourself)
  • Tools and equipment you buy and use for work
  • Professional fees and subscriptions (for example, union fees or professional body membership)
  • Work-related travel (but not commuting to and from work)
  • Home office expenses if you work from home (a portion of rent, utilities, and internet)
  • Glasses and contact lenses if required for work
  • Training and education directly related to your job

Keep receipts and records for all deductions. The ATO may ask for evidence if you claim a large deduction or if your claim is unusual for your industry.

You may also be entitled to tax offsets. These are different from deductions. An offset reduces the tax you owe directly, rather than reducing your income. If you have paid tax on foreign income, you can claim a foreign income tax offset. If you have dependents or other circumstances, you may qualify for other offsets. Ask a tax agent if you are unsure.

What Happens If You Don't Comply

Failing to meet your ATO tax obligations can result in serious penalties. If you do not lodge a tax return, the ATO can issue a default assessment and charge you a penalty of up to 75% of the tax owing. If you provide false information, you may face criminal prosecution.

Penalties also apply if you do not provide your TFN to your employer. Your employer can be fined, and you may face back-tax bills with interest. If you are on a temporary visa, tax non-compliance can affect your visa status and future visa applications.

If you make a mistake on your tax return, contact the ATO as soon as you notice. The ATO is often willing to work with you if you correct the error voluntarily. Do not ignore ATO letters or bills.
