Black Out Your TFNYou Are Allowed To
Your tax file number is for life and only a handful of organisations may legally ask for it. A real estate agent is not one of them. Redacted in your browser. Nothing uploaded.

The OAIC says this in plain words
The Office of the Australian Information Commissioner states: “If a document you’ve been asked to supply includes your TFN, you’re allowed to cross out or remove your TFN before you hand over the document.”
The Privacy (Tax File Number) Rule 2015 governs how TFN information may be collected, stored, used and disclosed. The list of organisations that may ask for your TFN is short: your employer once you have been hired, your bank or financial institution, your superannuation fund, your registered tax agent, and government agencies administering payments you are entitled to.
Nobody else has a legal right to ask. The OAIC also advises keeping TFN information in a safe place and destroying what you no longer need, precisely to prevent identity theft.
There can be financial consequences for withholding your TFN from an organisation that IS entitled to it, such as being taxed at the highest marginal rate on interest. That is a reason to give it to your bank, not to an agent processing a rental application.
Where Your TFN Turns Up
Check each of these before you attach a file.
Cover these
- Payslips, often near your employee number
- Superannuation statements

- Employment onboarding paperwork
- Bank interest statements
Leave these visible
- Your name
- Your employer
- Pay period or tax year
- Gross and net income figures
- Fund or account name, without the number
How It Works
Under a minute, and the file never leaves your device.
Open the document
Drop the payslip, statement or PDF in. Your browser handles it locally.
Cover the TFN
Draw over all nine digits. Do not leave a partial number visible.
Export and send
Download the flattened copy and share that instead of the original.
Your documents never leave your browser
A TFN is issued once and used for the rest of your life. You cannot change it the way you would change a leaked password, so every unnecessary copy is a permanent exposure rather than a temporary one.
RedactID does not add another copy. There is no upload step, because the redaction runs in the page you are already looking at. We never receive your file, so we cannot lose it.
How that actually worksCommon Questions
Am I allowed to cross out my TFN?
Yes. The OAIC states directly that if a document you have been asked to supply includes your tax file number, you are allowed to cross out or remove your TFN before you hand the document over.
Who can legally ask for my TFN?
A short list: your employer once you have accepted the job and are completing a Tax File Number Declaration, your bank or financial institution so it applies the right tax rate to interest, your superannuation fund, your registered tax agent, and government agencies administering payments you are entitled to. A landlord, a real estate agent, a recruiter before hiring you, or anyone contacting you out of the blue has no legal right to it.
What happens if I refuse to give my TFN?
To an organisation that is entitled to it, there can be financial consequences. Without a TFN your employer may withhold tax at the highest marginal rate, your bank may do the same on interest, and it can affect some payments. That is a reason to provide it where it is legitimately required, and no reason at all to provide it elsewhere.
Is a TFN like a US Social Security number?
Similar risk profile. It is a permanent identifier issued once and used for life, so it cannot be rotated like a password if it leaks. That permanence is why the ATO warns against sharing it in reply to unexpected emails or messages, and why scams targeting TFNs are common.
Does RedactID see my document?
No. Redaction runs in your browser on your own device. The file is not uploaded, not stored, and never reaches our servers.
Can the black box be removed later?
No. RedactID flattens the redaction into the exported file, so the covered pixels are gone. Drawing a black rectangle in a PDF viewer often leaves the text underneath selectable, which is how redaction failures happen.
Asked for a document that shows your TFN?
Cover it before you send. It takes under a minute.
