Your TFN and keeping it safe
A TFN is a unique number we issue to individuals. It is an important part of your tax and superannuation records, as well as your identity. It is also an important part of locating and keeping track of your superannuation savings. In the wrong hands, it could be used to commit fraud, so keep it safe. Make sure you protect your identity by keeping all your personal details secure, including your TFN.
We only issue one TFN to you during your lifetime – even if you change jobs, change your name, or move.
To find out more about how to protect your TFN and avoid identity crime, refer to Identity crime

Receiving interest, dividends and royalty payments
Non-resident withholding tax
If you are a foreign resident for tax purposes, you do not need a TFN if you only receive either:
- interest from an Australian bank account
- dividends from Australian shares
- royalty payments.
Your withholding tax is deducted at the tax rate applicable to your country of residence before you receive these payments. You do not need to declare this income on your Australian tax return.
However, you must:
- inform your investment bodies (for example, banks) that you are a non-resident
- provide an overseas address for statements.
For more information about withholding tax rates, phone +61 2 6216 1111 between 8.00am and 5.00pm (Australian Eastern Standard Time or Eastern Daylight-saving Time) Monday to Friday, and ask to be transferred to Personal tax enquiries.
TFN withholding tax
If you are a non-resident, you must not provide your TFN to investment bodies, unless your investment body is acting as your Australian superannuation fund manager.
It is not an offence not to quote a TFN to your superannuation fund, but if you do not supply it you may have more tax withheld than you need to.
If an investment body deducts TFN withholding tax from your interest, dividend or royalty payments, instead of non-resident withholding tax, you can apply for a refund of the difference. Do this by lodging an Australian tax return together with the statement showing tax has been deducted.
