Effective date: July 23, 2026 | Site: iftacalculation.com
By using iftacalculation.com (the "Site"), you agree to these Terms of Service. If you do not agree, please do not use the Site.
1. What This Site Is
The Site provides a free calculator that estimates International Fuel Tax Agreement (IFTA) quarterly fuel tax liability based on figures you enter (miles driven and fuel purchased by jurisdiction) and publicly available quarterly tax rate data.
2. Not Tax, Legal, or Financial Advice
The Site is an estimation tool only. It is not a substitute for your official IFTA quarterly return, professional tax preparation, or advice from a licensed accountant or tax professional. Tax rates change quarterly and jurisdictions may apply rules not reflected in this calculator (exemptions, weight-distance taxes, trip permits, etc.). Always verify current rates at iftach.org and confirm your filing with your base jurisdiction before submitting an official return.
3. No Warranty
The Site and its calculations are provided "as is" and "as available," without warranties of any kind, express or implied, including but not limited to accuracy, completeness, or fitness for a particular purpose. Tax rate data is sourced from official and quasi-official public sources and is believed accurate as of its last-verified date, but errors and delays in reflecting rate changes can occur.
4. Limitation of Liability
To the fullest extent permitted by law, IFTA Calculation and its operators are not liable for any direct, indirect, incidental, or consequential damages — including penalties, interest, or other losses — arising from your use of, or reliance on, the Site or its calculations.
5. Your Data
Trip figures you enter are processed locally in your browser and are not transmitted to or stored on our servers. See our Privacy Policy for details on cookies and advertising.
6. Third-Party Links and Advertising
The Site may display links or advertising for third-party products and services (for example, fuel cards or IFTA filing services), including ads served through Google AdSense. We are not responsible for the content, accuracy, or practices of any third-party site linked from or advertised on the Site. Any commercial relationship (such as an affiliate link) does not constitute an endorsement of quality or fit for your specific needs — please evaluate any third-party offer independently.
7. Intellectual Property
The design, text, and code of the Site are owned by IFTA Calculation unless otherwise noted. Publicly sourced tax rate data remains the property of the respective issuing jurisdictions and IFTA, Inc.
8. Changes to the Site or Terms
We may update these Terms, the calculator, or tax rate data at any time without prior notice. Continued use of the Site after changes constitutes acceptance of the updated Terms.
9. Governing Law
These Terms are governed by the laws of the jurisdiction in which IFTA Calculation is operated, without regard to conflict-of-law principles.
