Corrections policy

1. Rectification of Material Errors

Material errors — defined as an incorrect statutory figure, a misstated regulatory rule, or a flawed calculation — are corrected directly on the affected page. Crucially, this is accompanied by a dated editorial note explicitly detailing what was changed and why. We strictly prohibit the practice of quietly deleting or rewriting a substantive mistake without a public record of the alteration.

Minor typographical, grammatical, or formatting adjustments that do not alter the substance or interpretation of the text are implemented without a formal correction note.

In instances where an error has impacted a calculator's output, we conduct a comprehensive audit to determine if the flawed underlying figure in the central tax-variable record has affected any other pages, ensuring all instances are corrected simultaneously.

2. Pre-emptive Correction via Status Labelling

Certain content on this site bears the 'Awaiting expert review' label because a qualified reviewer has not yet validated it (refer to the Expert Review Policy). We consider this label a form of pre-emptive correction: it communicates unambiguously that the content is a provisional working draft rather than a finalised, legally verified position.

Our editorial stance is conservative: we will always choose to over-label content as unreviewed rather than risk a reader mistakenly assuming a complex topic has received professional sign-off.

3. Submitting a Correction Request

We rely on our community to help maintain our standards. Please use the Contact and Complaints page to report issues. To expedite the process, include the specific page URL, the exact figure or claim you are challenging, and, where possible, a link to the authoritative public source that supports your correction.

We commit to acknowledging every correction request promptly and aim to either implement the fix or provide a detailed explanation of our reasoning within a reasonable timeframe.
