"IFTA compliance should not require expensive software or a CPA on retainer. Every owner-operator deserves a free, accurate tool that gives them a clear quarterly tax picture in minutes — not hours."
Our Mission
IFTACalculators.com was built with a straightforward goal: give commercial truck drivers, owner-operators, and small fleet managers a completely free, accurate, no-signup IFTA quarterly tax calculator.
The trucking industry already deals with enormous complexity — hours of service rules, DOT compliance, fuel costs, maintenance, and more. The last thing a driver should have to worry about is whether their IFTA math is right. That is what this tool handles. Enter your miles and gallons per state, press calculate, and get a printable quarterly report in seconds.
We are not affiliated with IFTA, Inc., any government agency, or any trucking company. We are independent builders who believe that access to accurate tax calculation tools should be free and available to anyone.
What Makes This Calculator Different
The Team
IFTACalculators.com is maintained by a small independent team with backgrounds in web development, tax compliance software, and the transportation industry. We don't have a corporate parent or VC funding — just a commitment to keeping this tool free and accurate for the truckers who need it.
Data Sources & Accuracy
All IFTA fuel tax rates in this tool are sourced from the official IFTA, Inc. Tax Rate Matrix, published quarterly at iftach.org. We update rates after each quarterly release (January, April, July, and October).
The calculation methodology follows the IFTA Articles of Agreement, Section R1100, which defines the official 4-step formula for computing quarterly fuel tax liability. Surcharge calculations for Kentucky, Virginia, New York, and New Mexico follow the specific rules defined in each jurisdiction's IFTA program guidelines.
Important disclaimer: While we make every effort to maintain accuracy, this tool is for estimation purposes only. Tax rates change every quarter. Always verify current rates at iftach.org and consult a qualified tax professional before submitting your official IFTA return. We are not responsible for errors in your official filings.
Privacy & Data
IFTACalculators.com does not collect any of the data you enter into the calculator. All calculations happen entirely within your browser — nothing you type is ever sent to our servers. We do not require an account, do not store mileage or fuel data, and do not sell user information. See our full Privacy Policy for details.
