GSTCal is a website that offers free Australian GST calculators and plain-English guides to goods and services tax. These Terms of Service explain how you may use the site, and what you can expect from GSTCal in return.

By accessing or using GSTCal, you agree to be bound by these Terms and by any local laws that apply to your use of the site. If you do not agree with any part of them, please stop using the site.

GSTCal is an informational website with calculators and guides about Australian goods and services tax (GST). We are not a government agency, a tax agent, an accountant or a financial adviser, and we do not provide personal financial, legal or tax advice.

GSTCal is intended for people aged 18 and older. If you are under 18, you may not use the site. By using it, you confirm that you meet this requirement and that you are legally able to enter into an agreement.

GSTCal grants you a limited, non-exclusive, non-transferable license to view the content on the site for your own personal, non-commercial use. This license does not transfer title to any material on the site. It ends automatically if you breach these Terms.

• Remove copyright, trademark, or other proprietary notices.
• Transfer the materials to another person or mirror them on any other server.

All content on GSTCal is owned by the site owner or its licensors. This includes text, images, graphics, logos, design, and software. It is protected by copyright, trademark, and other intellectual property laws. You may not reproduce, republish, or distribute any of it without our express written consent.

If you email us questions, feedback or corrections, you keep ownership of what you send. You allow GSTCal to use it to improve the site, such as fixing an error you reported. Please do not send us personal financial details, tax file numbers or information about other people.

GSTCal is free to use and is paid for by advertising shown through Google AdSense. Ads are supplied by Google and its partners, and an ad on this site is not a recommendation from GSTCal. If a page ever contains affiliate or sponsored links, the page says so, as explained in our Affiliate Disclosure.

GSTCal may link to external websites, such as the Australian Taxation Office and other government sites. We do not control these sites and do not endorse their content. We are not responsible for anything on a linked site, and you use those sites at your own risk.

Your use of GSTCal is also governed by our Privacy Policy, available on this site. Please read it to understand how information is collected and used.

The content on GSTCal, including every calculator result, is general information only. It does not take your personal circumstances into account, and it cannot tell whether a particular sale is taxable, GST-free or input-taxed.

Tax rules and thresholds can change. GSTCal does not provide financial, legal or tax advice. Confirm figures with the Australian Taxation Office or a registered tax agent before you rely on them.

All materials on GSTCal are provided “as is,” without warranties of any kind, express or implied. GSTCal makes no representations about the accuracy, completeness, reliability, or fitness of the content for any particular purpose.

The materials on GSTCal may contain technical or typographical errors, and tax rules can change. GSTCal does not warrant that any material is accurate, complete, or current.

We may change the materials at any time without notice. We are under no obligation to update them.

To the fullest extent permitted by law, GSTCal, its owner, and its agents are not liable for any direct, indirect, incidental, consequential, special, or exemplary damages. This applies to damages arising from your use of, or inability to use, the site, even if we have been advised of the possibility of such damages. This includes losses from relying on a calculator result or an explanation on the site.

Some jurisdictions do not allow certain limitations of liability, so these limits may not apply to you.

You agree to indemnify, defend, and hold harmless GSTCal, its owner, and its affiliates from any claims, damages, losses, or expenses, including reasonable legal fees. This covers claims arising from your use of the site, your violation of these Terms, or your violation of any third party’s rights.

GSTCal may terminate or restrict your access to the site at any time, without notice, and for any reason, including a breach of these Terms. Once access ends, your right to use the site stops immediately.

GSTCal is not liable for any failure or delay caused by circumstances beyond our reasonable control. These include acts of God, war, terrorism, natural disasters, internet outages, and government actions.

GSTCal may revise these Terms at any time without prior notice. If you keep using the site after changes are posted, you accept the revised Terms. Please check this page from time to time.

Any claim relating to GSTCal is governed by the laws in force in Australia.

If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions stay in full force and effect.

These Terms, together with the Privacy Policy and any other notices on GSTCal, make up the entire agreement between you and the site. They replace any prior agreements.

These Terms are effective from 8 November 2026.
