Corrections policy

Clear corrections are part of making utility tools dependable: material changes should be reviewed, tested and explained.

What counts as a correction

A correction may be needed when a formula, rounding rule, example, instruction, limitation, source attribution or accessibility statement is inaccurate or materially unclear. Spelling and layout fixes that do not change meaning may be corrected without a public method-version change.

How material issues will be handled

  1. Record the report without collecting unnecessary personal information.
  2. Reproduce the issue against the current formula specification and test cases.
  3. Check the relevant primary or Australian source where one exists.
  4. Correct the page, method or code and rerun its regression checks.
  5. Update the visible version or review date when the meaning or result changes.

Reporting an issue

Use the contact form. A useful report includes the page address, inputs used, result observed and result expected. Sensitive personal or project data should not be included.
