Corrections Policy

If you find an error — a calculation, a reference value, a translation or a broken export — please tell us using the “Report an issue” link on any page.

• Reports about regulatory values and calculations are prioritised.
• When we correct a reference value, we create a new ruleset version rather than editing the old one, and record the change in our change log. Saved projects keep their original version until you choose to update them.
• Significant corrections to guides are noted on the page with the date of the change.
