- A partnership needs a TFN for tax reporting and an ABN to operate, both play different but essential roles in staying compliant and getting paid without issues.
- You can apply for both TFN and ABN together through a single ABN application, making setup faster and reducing the risk of delays or duplicate processes.
- Partnerships don’t pay tax directly, income is reported at the partnership level but taxed in each partner’s individual return, so accurate setup and reporting are critical.
TFN and ABN for partnership is one of the most common areas of confusion when starting a business in Australia, especially when you’re unsure whether you need both, how they work together, or how to apply correctly.
If you get this wrong, it can lead to delays in registration, incorrect tax reporting, or even unnecessary withholding tax on your income. And with multiple partners involved, the stakes are higher.
In this guide, we’ll walk you through exactly what a partnership needs, including whether you need a TFN and ABN, how each one works, and how to apply for both in the simplest way possible.
Always request your TFN during the ABN application itself. Missing this step is one of the most common reasons partnerships face unnecessary delays and extra paperwork later.
Do partnerships need both a TFN and ABN in Australia?
Yes, a partnership needs both a TFN and an ABN, and they serve completely different purposes.
Even though a partnership isn’t a separate legal entity, the ATO treats it as a separate tax entity. That means the partnership must have its own Tax File Number (TFN) for tax reporting, in addition to each partner’s individual TFN.
At the same time, if the partnership is running a business or enterprise, it also needs an Australian Business Number (ABN). This is what you’ll use to operate commercially, such as issuing invoices, registering for GST, and dealing with other businesses.
How it works in practice
- Partnership TFN: Used to lodge the partnership tax return and report total income (the partnership itself doesn’t pay tax)
- Partner’s TFN: Each partner declares their share of income and pays tax individually
- Partnership ABN: Used for invoicing, GST, and day-to-day business operations
If you only register one and not the other, you’ll run into issues quickly:
- Without an ABN: clients may withhold up to 47% tax from payments
- Without a TFN, you generally can’t lodge a partnership tax return or report income correctly to the ATO
Your ABN lets your partnership operate, while your TFN keeps it compliant with the ATO.
How does a TFN work for a partnership in Australia?
A partnership TFN is used to report the partnership’s income to the ATO, not to pay tax.
This is a key distinction. Even though a partnership must register for its own TFN, it doesn’t pay income tax as a separate entity. Instead, the TFN is used to track the business’s total financial activity and correctly allocate profits (or losses) to each partner.
In practice, the partnership TFN is required to:
- Lodge the partnership tax return each year
- Report total income, expenses, and net profit or loss
- Show how that income is split between partners based on the partnership agreement
Once this return is lodged, the ATO uses the partnership TFN to link each partner’s share of income to their individual tax records.
That’s where your personal TFNs come in.
Each partner then:
- Declares their share of the partnership income in their own tax return
- Pays tax at their individual marginal tax rate
- Remains personally responsible for their portion of tax obligations
This structure is what makes partnerships unique, the business reports income, but the individuals pay the tax.
It also means accuracy matters. If the partnership TFN isn’t set up or used correctly, it can lead to:
- Inability to lodge a valid partnership tax return
- Mismatches between partnership income and individual tax returns
- Increased risk of ATO scrutiny or delays
In short, the partnership TFN acts as the ATO’s way of tracking your business activity, while ensuring each partner is taxed correctly on their share, making it a critical part of staying compliant from day one.
For most partnerships, the most efficient path is: Apply once through the ABN application and request your TFN at the same time
This reduces delays, avoids duplicate applications, and ensures your partnership is fully set up for both tax reporting and business operations from day one.
What’s the difference between a TFN and ABN for a partnership?
Both TFN and ABN are required for partnerships but they serve very different roles in how your partnership runs and stays compliant. Here’s how they compare in practice:
Aspect | Partnership TFN | Partnership ABN |
Core role | Used by the ATO to track your partnership’s income and reporting obligations | Used to identify your partnership as a business when dealing with clients, suppliers, and government |
What it’s used for | Lodging the partnership tax return and allocating income to each partner | Issuing invoices, registering for GST, and receiving payments without withholding |
Who interacts with it | Primarily the ATO and your accountant during tax time | Customers, suppliers, banks, and government agencies |
How it affects tax | Ensures income is correctly split and taxed in each partner’s personal return | Helps avoid PAYG withholding (generally at the top tax rate) if an ABN is not quoted when required |
Visibility | Private, not shared on invoices or public documents | Public, typically included on invoices and required to be quoted to avoid PAYG withholding on payments |
Timing of use | Mainly during tax reporting periods (e.g. lodging returns) | Used daily in business operations and transactions |
What happens if missing | You can’t lodge a valid partnership tax return or report income properly | Payments may be withheld, and you may not be able to trade or invoice correctly |
Both play a distinct but equally important role.
In simple terms: your TFN keeps your partnership compliant with tax reporting, while your ABN allows you to operate, invoice, and get paid without disruptions.
How do you apply for a TFN and ABN for a partnership?
When setting up a partnership, you don’t need to go through separate processes for your TFN and ABN, you can apply for both at the same time through a single ABN application.
This is where many business owners get confused, especially when the application asks for a TFN upfront.
Can you apply for a TFN and ABN at the same time?
Yes. When you apply for an ABN for a new partnership through the Australian Business Register (ABR), you can request a partnership TFN as part of the same application.
- However, during the process, you may see a field asking for a TFN, along with a note saying your application could be delayed if it’s not provided.
Here’s the key point:
- If your partnership doesn’t already have a TFN, you can skip this field.
- It’s a standard question in the form, not a requirement for new partnerships.
As long as you follow the correct steps, your TFN request will still be processed alongside your ABN application.
How the combined application for TFN and ABN actually works
When you apply for a partnership ABN:
- You select “partnership” as your business structure
- Enter details for all partners
- Complete your business activity information
As part of this process, the system allows you to:
- Apply for an ABN
- Request a partnership TFN
- Register for GST (if required)
Once submitted:
- Your ABN may be issued immediately (if approved)
- Your TFN is processed separately by the ATO and sent to you later
Do you ever need to apply separately for TFN and ABN?
In most cases, no.
But you may need to apply for a TFN separately if:
- Your ABN was already set up without requesting a TFN
- Your initial application was incomplete or unsuccessful
In that case, you can apply using the ATO’s “TFN application for companies and other organisations” form.
Even though the process is straightforward, these are common issues:
- Assuming a TFN must be entered before applying: you can skip it for new partnerships
- Missing the TFN request during the ABN application: leads to extra admin later
- Expecting both numbers to be issued instantly: TFN takes longer
What are the common TFN and ABN mistakes partnerships make?
Even though the setup is fairly straightforward, a few common mistakes can quickly lead to delays, compliance issues, or even cash flow problems:
- Using a partner’s TFN instead of a partnership TFN: it might seem easier, but it can mess up how your income is reported
- Skipping the TFN request during ABN application: many people think they’ll sort it later, but it just adds extra admin
- Starting to invoice without an ABN: this can catch you off guard, as clients may withhold up to 47% of your payment
- Mixing personal and partnership income: especially common in early stages, but it increases the risk of ATO mismatches
- Expecting TFN and ABN to be issued together: ABN is often quick, but TFN usually takes longer
- Entering incorrect partner details: small errors here can delay or even reject your application
The good news? These are all easy to avoid once you know what to look for. Getting your setup right from day one saves time, avoids stress, and keeps your partnership running smoothly.
Your ABN impacts cash flow immediately. If you start invoicing without one, clients may be required to withhold tax at the top rate, which can delay payments and create avoidable admin.
What are the tax obligations for a partnership after registration?
Once you’ve got your TFN and ABN set up, your partnership is officially ready to operate but there are a few ongoing tax obligations you need to stay on top of.
At a high level, the partnership is responsible for reporting income, while the partners are responsible for paying tax on their share.
Here’s how that works in practice:
- The partnership must lodge an annual partnership tax return with the ATO
- This return reports total income, expenses, and net profit (or loss)
- The partnership then distributes that income between partners based on the partnership agreement
- Each partner must include their share in their individual tax return and pay tax accordingly
If your partnership is registered for GST, you’ll also need to:
- Lodge Business Activity Statements (BAS)
- Report and pay GST (if applicable)
Depending on your setup, you may also have additional obligations, such as:
- PAYG withholding if you have employees
- Superannuation contributions for staff
The key thing to remember: even though the partnership doesn’t pay income tax itself, it still has clear reporting responsibilities and missing these can lead to penalties or compliance issues.
Getting your structure right is just the first step. Staying compliant is what keeps your business running smoothly long-term.

Frequently Asked Questions
Do you need to register for GST as a partnership?
Not every partnership needs to register for GST, but once your annual turnover reaches $75,000 or more, it becomes mandatory.
If you’re below this threshold, registration is optional. Some partnerships still choose to register to claim GST credits on business expenses.
Once registered, you’ll need to:
- Add GST to invoices
- Lodge BAS regularly
What if I don’t have a TFN when applying for an ABN?
You can skip the TFN field during the ABN application if your partnership doesn’t already have one. The TFN can still be requested as part of the process.
Do I need a new TFN and ABN if the partnership structure changes?
Yes. If there are significant changes such as adding/removing partners or changing the structure, you may need to cancel and re-register for a new ABN and TFN.
