Corrections Policy
How MoneyToolkit handles possible errors, outdated sources, and unclear results.
Last updated: 28 July 2026
Report a possible error
Email contact@gstcalculate.com.au with the page URL and a short description of what appears incorrect. For calculator issues, include the inputs needed to reproduce the result, but do not send tax file numbers, ABN credentials, invoices containing customer details, bank information, or complete BAS records.
A link to an official source, legislation, regulator guidance, or other supporting evidence helps us investigate more quickly.
What happens next
- 1
Reproduce and verify
We check the page, calculation path, cited source, and relevant assumptions.
- 2
Assess materiality
We distinguish a factual or calculation error from a reasonable difference in assumptions or circumstances.
- 3
Correct the source and explanation
If a material error is confirmed, we update the calculation or text and review related pages that may rely on the same information.
- 4
Record meaningful changes
We update the page review date when the correction materially changes a result, threshold, benchmark, or conclusion.
A different estimate is not necessarily an error
Actual GST treatment can depend on registration, tax periods, invoice validity, supply classification, apportionment, special rules, and transaction facts the calculator cannot know. Verify material amounts in your records or with a registered tax or BAS agent.
Privacy when reporting
Send only the minimum information needed to reproduce the issue. We do not need identity documents, account numbers, tax file numbers, addresses, or complete financial records. See the privacy policy for more information.
