- There’s no separate TFN application for foreigners, foreign entities apply using the standard TFN application for organisations, with additional verification requirements.
- A TFN is only required when your entity has Australian tax obligations, such as earning income in Australia or needing to lodge a tax return.
- The application process is more structured and documentation-heavy, so getting your details accurate from the start is key to avoiding delays.
Navigating a TFN application for foreigners can be confusing, especially when you’re unsure whether you actually need one or how the process works in Australia.
If you get this wrong, it can delay your ability to meet tax obligations, receive income, or move forward with plans like starting a business as a foreigner. And with no clear “foreign TFN” category, many applicants end up following the wrong process altogether.
In this guide, we’ll explain:
- When a TFN is required for foreigners
- How the application process works
- What foreign entities need to apply correctly in Australia.
Before applying, map out your exact Australian activity (income, clients, or operations), this determines not just whether you need a TFN, but also whether you should be applying for an ABN alongside it.
What is a foreign entity in Australia?
In the Australian tax context, a foreign entity generally refers to a business or organisation that is not a resident of Australia for tax purposes.
This can include:
- Foreign companies registered outside Australia
- Foreign trusts with overseas control or beneficiaries
- Foreign partnerships where the partners are based overseas
In simple terms, if your entity is established or managed outside Australia but has dealings within Australia, it may be treated as a foreign entity for tax purposes.
This distinction matters because foreign entities have different tax obligations, including when and how they may need to apply for a TFN.
Does a foreign entity need a TFN in Australia?
Not every foreign entity needs a TFN but if you have tax obligations in Australia, you likely will.
A TFN is required when your entity needs to interact with the Australian tax system, particularly for reporting and compliance purposes.
In most cases, a foreign entity will need a TFN if it:
- Earns Australian-sourced income (e.g. services, investments, or business activities)
- Is required to lodge an Australian tax return
- Has a tax presence or ongoing operations in Australia
For example, this may apply if a foreign company:
- Provides services to Australian clients
- Holds Australian investments or property
- Operates or conducts business activities within Australia
If your entity falls into any of these categories, having a TFN becomes essential to report income correctly, meet ATO requirements, and avoid delays in compliance.
On the other hand, if your entity has no Australian income and no reporting obligations, a TFN may not be required.

TFN vs ABN for foreign entities: What’s the difference in Australia?
Foreign entities often confuse TFN and ABN but they serve completely different purposes in Australia’s tax system. Understanding this distinction is key to applying correctly and staying compliant.
Here’s how they compare in practice:
Aspect | TFN (Tax File Number) | ABN (Australian Business Number) |
Core role | Used by the ATO for tax reporting and identification | Used to identify your business in commercial activities |
Who needs it | Entities with tax obligations in Australia | Entities carrying on an enterprise in Australia |
Main use | Lodging tax returns and managing tax compliance | Invoicing, dealing with clients, and business transactions |
Tax impact | Required to report income and meet ATO obligations | Helps avoid withholding at the top tax rate if required |
Visibility | Private (used within ATO systems) | Public (shared on invoices and business documents) |
When required | When you need to interact with the ATO for tax purposes | When you are actively operating or trading in Australia |
A TFN is for tax compliance, while an ABN is for business operations.
Many foreign entities need one or both, depending on whether they are earning income, operating a business, or both.

For foreign entities, the real complexity isn’t the form, it’s how the ATO interprets your presence in Australia. The same activity can trigger different obligations depending on how your entity is structured and operating.
How to apply for a TFN as a foreign entity in Australia
Applying for a TFN as a foreign entity isn’t a simple online task and that’s where most businesses misstep.
There’s no separate TFN application for foreign entities. Instead, foreign companies, trusts, and partnerships apply using the standard TFN application for companies and other organisations (NAT 3799), the official ATO pathway for non-individual entities.
1. Which TFN application form should foreign entities use?
Foreign entities must use the TFN application for companies and other organisations (NAT 3799).
Foreign entities must apply using the same form as Australian entities, but with additional scrutiny.
In some cases,
- You may be able to apply for a TFN alongside an ABN, but this depends on your structure and registration pathway.
- If not, the TFN application is submitted separately using the organisation form.
2. What information and identity details do you need to provide?
The ATO doesn’t just register your entity, it verifies who controls it and how it operates.
You’ll need to provide:
- Full legal details of the entity (including country of incorporation)
- Nature of your activities in Australia
- Details of key individuals (directors, partners, trustees)
In many cases, this also involves:
- Certified copies of documents
- Overseas registration records
- Identity documents for applicant entity
This is where incomplete or inconsistent information often causes delays.
3. Is the TFN application process online or manual for foreign entities?
The TFN application process for foreign entities is typically manual, not fully online.
Foreign entities can apply for a TFN online through the ABR in many cases, including as part of an ABN application. However, depending on the entity type and circumstances, additional verification or documentation may still be required
Typically:
- The application is paper-based or agent-assisted
- It is reviewed manually by the ATO
- Additional information may be requested if required
Processing is not immediate, it’s realistic to allow several weeks, especially where overseas verification is involved.
4. Why getting your TFN application right the first time matters
Getting your TFN application right the first time is critical because errors or incomplete details can delay processing and create compliance issues with the ATO.
Applying for a TFN as a foreign entity isn’t just about completing a form, it’s about setting up your tax presence in Australia correctly.
If your application isn’t done properly, it can lead to:
- Delays in receiving your TFN
- Follow-ups or re-submissions
- Issues meeting your tax obligations on time
But when everything is accurate and complete from the start, the process becomes far smoother, and you’re set up to manage reporting and compliance without friction.
In short: this is a one-time setup that’s more detailed than it looks and getting it right upfront saves you time, effort, and complications later.
What documents are required for a foreign entity TFN application?
One of the biggest differences when applying for a TFN as a foreign entity is the level of documentation required. Unlike individual applications, the ATO needs to verify both the entity and the people behind it, which means you’ll need to provide more detailed information upfront.
Here’s what is typically required:
Entity registration and business details
You’ll need to provide documents that confirm your entity’s existence and structure, such as:
- Certificate of incorporation or registration
- Business registration details from your home country
- Registered business name and address
- Nature of your business activities (especially in Australia)
These documents establish that your entity is legitimate and operating as claimed.
Details of key individuals (associates)
The ATO requires information about the people who control or manage the entity, including:
- Directors (for companies)
- Partners (for partnerships)
- Trustees (for trusts)
For each individual, you may need to provide:
- Full name and date of birth
- Role within the entity
- Contact details
Proof of identity documents
Identity verification is stricter for foreign entities. You may be asked to provide:
- Certified copies of identity documents (e.g. passports)
- Documents that confirm identity and association with the entity
- Supporting records that match your registration details
Documents often need to be certified copies, not originals, and must meet ATO certification requirements.
Additional supporting information (if required)
Depending on your application, the ATO may request:
- Clarification of business activities in Australia
- Additional documents to verify overseas registration
- Further identification for associates
Can foreign entities apply for a TFN online in Australia?
In most cases, foreign entities cannot apply for a TFN through a simple online self-service process like individuals can.
There’s no myID-based application or instant online approval. Instead, the process typically involves:
- Completing the TFN application for companies and other organisations
- Submitting it via paper form or through a registered tax agent
- Undergoing manual review by the ATO
The reason is straightforward: the ATO needs to verify overseas entities and their associates, which requires additional checks that aren’t handled through standard online systems.
Are there any online TFN application options for foreign entities?
In some cases:
- You may apply for a TFN as part of an ABN registration through the Australian Business Register (ABR)
- This is the closest to an online pathway, but it still depends on your eligibility and structure
How long does it take to get a TFN for a foreign entity in Australia?
TFN applications for foreign entities are not processed instantly and that’s by design. Because the ATO needs to verify an overseas entity and its controlling individuals, the process involves manual checks and document validation, which naturally takes longer than individual applications.
- In most cases, it’s realistic to allow several weeks from the time a complete application is received.
- If your application is straightforward and all documents are clear, it may move faster.
- However, where additional verification is required, especially across jurisdictions, timelines can extend.
What typically affects processing time is not just the method of application, but the quality and consistency of the information provided.
- Incomplete forms, mismatched details between entity records and identity documents, or missing certified copies are some of the most common reasons applications are delayed.
- Similarly, if the ATO needs clarification on your business activities in Australia or the identity of key individuals, they may come back with follow-up queries, which can add to the timeline.
It’s also important to note that submitting multiple applications to “speed things up” has the opposite effect, it can create duplication in the system and slow down processing further.
- In practice, the fastest way to get your TFN is not by rushing the application, but by getting it complete and accurate the first time.
- Planning ahead and allowing for a realistic processing window ensures you’re not held up when it comes to meeting your tax obligations or moving forward with business activities in Australia.
A TFN is free to apply for, and you should never submit multiple applications, it can actually slow down the process instead of speeding it up.
When should a foreign entity apply for a TFN in Australia?
Timing matters more than most foreign entities realise. Applying too late can delay compliance, while applying too early without a clear requirement can create unnecessary admin.
In general, a foreign entity should apply for a TFN once it knows it will have tax obligations in Australia.
This typically means applying before:
- Lodging an Australian tax return
- Receiving Australian-sourced income that needs to be reported
- Formalising business or investment activities that bring the entity into the Australian tax system
For example, if your entity is about to:
- Start providing services to Australian clients
- Earn income from Australian investments or assets
- Establish an operational or reporting presence in Australia
That’s usually the right point to initiate your TFN application.
Waiting until after income is received or obligations arise can lead to:
- Delays in reporting
- Backdated compliance work
- Additional coordination with the ATO
In practice, the best approach is to apply as soon as your Australian tax obligations become clear, not after they’ve already started.

Frequently Asked Questions
Can a foreign entity apply for a TFN before earning income in Australia?
Yes. You can apply once it’s clear you will have tax obligations in Australia, rather than waiting until income is received.
What happens if entity details change after receiving a TFN?
You don’t apply for a new TFN. Instead, you must update the ATO with the new details (such as changes in structure, ownership, or contact information).
What happens if a foreign entity operates in Australia without a TFN?
You may face delays in lodging tax returns and meeting ATO obligations, which can lead to compliance issues.
