Effective 20 September 2026. These terms apply to the free CalcGST tools and content, operated by Star Shop com (ABN 83 443 122 821).
General information and arithmetic
The tools apply the inputs and assumptions shown. They do not provide personalised tax, accounting or legal advice, establish your GST registration obligations, verify a transaction, lodge a BAS or guarantee that a document satisfies every applicable requirement. Check official guidance and seek appropriate advice for your circumstances.
Your documents and records
You are responsible for the accuracy of business details, customer information, quantities, prices, tax treatment and payment instructions. Review every document before use. A receipt should only be issued for a payment you have independently confirmed.
Local draft storage is a convenience, not a record-keeping or backup service. Save final documents securely outside the browser. We cannot restore deleted drafts or verify that a payment has occurred.
Appropriate use
Do not use the site to create misleading invoices, false receipts, impersonate a business or interfere with the service. Generated documents are provided for your legitimate business use. Our explanatory articles and branding remain the property of their respective owners.
Availability and limitations
We aim for reliable tools but cannot promise uninterrupted availability or error-free results in every environment. Features and content may be corrected, changed or withdrawn. Nothing in these terms excludes rights or remedies that cannot lawfully be excluded, including applicable rights under Australian Consumer Law.
Contact and corrections
Report problems or ask questions at hello@calcgst.au. Include a small, non-sensitive example where possible. Our privacy policy explains how inputs, drafts and enquiries are handled.
