What you need first:
- All of your fuel receipts for your truck or fleet for the current due quarter
- A list of the miles driven in each jurisdiction during the current due quarter. (to instantly purchase and download a state-by-state mileage and route calculator, see this link first and double-check your mileage before doing your IFTA.)
How to use the simple free calculator:
- Click the “Free Fuel Tax Calculator” link
- Enter a name for your truck or company and then press the “Enter” key on your keyboard
- Click the “Add miles” tab at the top, and then the “Add Miles” button to perform a new mileage entry
- Select the jurisdiction and add the taxable and non-taxable mileage numbers for that jurisdiction and then save by either pressing the “Enter” key on your keyboard, or by clicking the “Save” button
- REPEAT step 4 for all of the jurisdictions in which your truck or fleet drove
- Click the “Add Diesel Fuel” tab
- Click the “Add diesel purchase” button
- Select the jurisdiction and add the paid fuel amount in gallons for that jurisdiction and then save by either pressing the “Enter” key on your keyboard, or by clicking the “Save” button
- REPEAT step 8 for all of the jurisdictions in which you bought fuel
- Click the “Final Report” button at the bottom of the page to view your work at any time
- With the “Final Report” screen open, you now can use the totals and the amounts to write into your state IFTA form, or to double-check your own calculations. (with any member account on the site you can print or email this report on this step. Printing and email is not available on the free calculator though.)
- To do a fresh report, click on “Start Over” at the bottom. BUT BEWARE that any numbers you have entered will be lost if you start over or if you leave the calculator page.
- TIP: Your total tax due is always updated at the top-right as you perform each entry.
- TIP: NOTE that your truck or fleet MPG is always shown on the page and in the final report. If the MPG is not logically matching what you believe that your truck or fleet average should be, then you have likely forgotten to put in all of your entries for miles/kilometers or all of your fuel purchases!
