Redacting Tax File Numbers on Mortgage Documents

Tax file numbers should not appear on documents shared with lenders. A clean redaction workflow protects client privacy and keeps the broker aligned with obligations under the Privacy Act 1988 and the Privacy (Tax File Number) Rule 2015.

Why TFNs should not be shared

Tax file numbers are protected information under the Privacy Act 1988 and the Privacy (Tax File Number) Rule 2015 issued by the Office of the Australian Information Commissioner. Credit providers do not require TFNs to assess a home loan. Leaving TFNs on payslips, tax returns, or notices of assessment when sending to a lender creates a privacy risk without any assessment benefit.

Documents that typically show a TFN

Payslips sometimes show the last four digits of a TFN. Tax returns and notices of assessment display the full TFN. Some employer issued payment summaries also show the number. Any of these documents should be redacted before they leave the broker office.

Redacting effectively

Effective redaction means the TFN cannot be recovered from the document. Simply covering the number with a black rectangle in a PDF viewer is not enough because the underlying text often remains. Use a tool that genuinely removes the text layer or flattens the rectangle into the document image.

Key takeaways

  • Treat every TFN as protected information
  • Review payslips, tax returns, and NOAs for TFN data
  • Use redaction that removes the underlying text layer
  • Confirm redacted files before sharing with a lender
