Why you must supply your TFN if you want to avoid excess tax

Supplying your Tax File Number (TFN) is essential if you want to avoid paying unnecessary taxes in Australia. Without a TFN, businesses and financial institutions are required to withhold tax at the highest rates on payments such as salaries, interest, or superannuation.

By providing your TFN, you ensure that you're only taxed at the appropriate rates. If you haven’t applied for your TFN yet, it's highly recommended to do so to avoid excess tax and other potential complications.

What is a TFN and why is it important?

Your Tax File Number (TFN) is a unique number issued by the Australian Taxation Office (ATO) for tax and superannuation purposes. It's linked to your personal details, including your name, date of birth, and other identity documents. You will use this number throughout your life for tasks like lodging your tax return, applying for government benefits, and managing superannuation accounts. You can apply for a TFN online through the ATO website or Australia Post if you are an Australian resident.

The Privacy (Tax File Number) Rule 2015 outlines how organisations should handle your TFN information, including its collection, storage, and disclosure. Even though strict regulations apply to how businesses and government departments, including the ATO, manage your TFN information, it’s essential that you also keep your records safe. Be sure to store documents containing your TFN securely and destroy any unnecessary records to prevent identity theft.

Why you need to supply your TFN

If you live in Australia or run a business here, having a Tax File Number (TFN) is crucial. Without one, you might face higher tax withholding rates, issues with accessing government benefits, and complications when lodging your tax return or applying for an Australian Business Number (ABN). Applying for a TFN is free, and you can do it online through platforms like Australia Post or Services Australia.

Not having a TFN can lead to financial issues. For example, employers and banks are required to withhold tax at the highest possible rates on your salary or interest payments if they don’t have your TFN. Resident employees without a TFN might have 47% of their unused leave withheld by their employer. Similarly, banks may withhold tax at the highest rate on interest payments without a TFN.

To avoid these unnecessary financial hurdles, make sure to apply for your TFN. It simplifies tax reporting, lowers withholding rates, and gives you access to various government benefits. If you haven’t got your TFN yet, it's important to get it sorted as soon as possible.

How to apply for a TFN

To apply for your Tax File Number (TFN), start by completing the online application form on the ATO website. Once you've submitted the form, print the application summary and gather the required identity documents for your interview.

Next, find a participating Post Office near you that accepts TFN applications. While it’s not necessary to book an appointment, you can schedule one if you prefer. You need to visit a participating Post Office within 30 days of printing your application summary, bringing along your summary and identity documents for the interview.

After the interview, your TFN should be mailed to the postal address on your application within 28 days. Be patient during the processing period and avoid lodging another application during this time.

Protecting your TFN and personal details

Keeping your Tax File Number (TFN) secure is essential to prevent identity theft and fraud. Your TFN should only be shared with trusted organisations, such as the Australian Taxation Office (ATO), employers, banks, and government agencies when required by law.

Certain situations where you may need to disclose your TFN include lodging a tax return, applying for government payments like pensions or benefits, starting a new job, or joining a superannuation fund. These organisations are permitted to use your TFN for purposes outlined by tax, superannuation, or personal assistance laws.

Where to find your TFN

Locating your Tax File Number (TFN) can be done in a few simple ways. You can access it online, check your physical records, or contact the relevant authorities for assistance.

One of the easiest methods is by logging into your myGov account and using ATO online services. Within your account, you can find your TFN in your profile, making it quick and convenient to retrieve whenever you need it.
