Editorial Policy & Corrections

ANZ GST Calculator is designed as a practical utility site. Our editorial approach is to make calculator results understandable, traceable, and appropriately limited.

Accuracy

Calculators show the arithmetic used to produce a result wherever practical. Supporting explanations are checked against official New Zealand and Australian tax sources.

Source Preference

Government tax authorities are preferred for current GST rates, thresholds, filing requirements, and legal or administrative guidance. Third-party material may be used for context but is not treated as a substitute for official guidance.

Corrections

If you identify a wrong formula, outdated rule, misleading statement, broken link, or technical problem, please contact contact@anzgstcalculator.com. We investigate reported issues and correct published information when a change is warranted.

Change Transparency

Material calculator or methodology changes are reflected in the relevant page content and, where useful, accompanied by an updated date. We do not intentionally publish claims about services or calculations that the site does not actually provide.

Editorial Limitations

The site does not provide personalised tax, accounting, financial, or legal advice. A calculator result should be independently checked before it is used for an official filing or a material business decision.
