Free IFTA Excel Spreadsheet & Trip Log Template
A ready-to-use quarterly IFTA workbook with automated SUMIF miles aggregation, fleet MPG calculation, and official Q3 2026 state tax rates pre-loaded.
The Pain of Manual IFTA Calculations in Excel
Managing quarterly IFTA compliance on a blank spreadsheet is tedious and notoriously error-prone. Every quarter, owner-operators and fleet managers have to manually research changing fuel tax rates across 48 contiguous states and 10 Canadian provinces.
To calculate taxes due by hand, you must write custom SUMIF formulas to sort mileage by state, calculate overall fleet MPG, divide miles into taxable gallons, and apply varying diesel rates alongside special jurisdiction surcharges. A single broken formula syntax or an outdated rate from a prior quarter can lead to miscalculated liabilities, penalties, interest charges, or an unexpected state audit.
Our free template solves the formula headaches with verified structure and pre-built math, while IftaDesk offers an instant, automated alternative.
What's Inside the Template Workbook
The downloadable .xlsx file includes three dedicated worksheets engineered to take you from daily trip logs to quarterly tax totals.
| Sheet Name | Core Purpose | Built-in Logic |
|---|---|---|
| Trip Log | Record daily odometer readings, routes, and fuel purchases | Total Miles calculation per trip (=Ending - Beginning) and bottom SUM totals for Miles and Gallons |
| Quarter Summary | Aggregate miles by jurisdiction and calculate estimated taxes due | SUMIF from Trip Log, MPG division (=Miles/MPG), VLOOKUP rate matching from Sheet 3, and Tax Due calculation (=Gallons*Rate) |
| State Tax Rates (3Q2026) | Official quarterly tax rates reference for all IFTA jurisdictions | Referenced by VLOOKUP in the Quarter Summary sheet for automated tax lookup |

Our Recommendation: Use Both Together
Excel spreadsheets are fantastic for keeping daily odometer logs and fuel receipt notes offline in your cab. But when the quarterly filing deadline arrives (April 30, July 31, October 31, January 31), reconciling multiple split-rate states and surcharge rules by hand is stressful.
Use our free spreadsheet to track daily miles, then enter your totals into IftaDesk to generate an audit-ready tax return summary in 3 minutes — 100% free with no registration required.
