File a quarterly fuel or road tax return
Open the return or refund of a scheme and period, read the lines and warnings, export it to Excel and mail it automatically every period.
Updated 18 October 2026
The Fuel & road taxes page prepares the return of every enabled scheme for any period. It has three tabs: Returns, Miles per jurisdiction and Rates.
Open a return
- Open the side menu (☰, top right) and choose Fuel taxes.
- On the Returns tab, choose the Scheme. Schemes are grouped as Fuel tax returns, Distance taxes and Fuel tax refunds.
- Choose the Year and the Quarter (or the Month for a monthly scheme).
- For a fuel tax return, choose the Fuel type.
- Read the return and its warnings (see below).
The heading shows the period, the filing due date and the state of the rates: Final rates, Preliminary rates or Rates missing. When no scheme is enabled yet, the page says so and links to the settings.
Read a fuel tax return
At the top you see Total miles, Total gallons, Fleet MPG and the result: Net due, or Net credit when you paid more tax at the pump than you owe. The calculation follows the IFTA rules:
- Fleet MPG = all miles of your qualified vehicles ÷ all gallons they bought.
- Per jurisdiction, Taxable gallons = its Taxable miles ÷ fleet MPG.
- Net taxable gallons = taxable gallons − Tax-paid gallons bought there.
- Tax due = taxable gallons × the Tax rate; the Credit = tax-paid gallons × the rate. A Surcharge due (for example in Kentucky and Virginia) is charged on all taxable gallons, without credit.
- Net = tax due + surcharge due − credit.
Per jurisdiction lists the member jurisdictions. Miles in places outside the scheme, such as Alaska or Mexico, are listed separately under Miles outside the scheme: they count in the total miles and fleet MPG, but are not a line on the return. Per vehicle shows each vehicle with Qualified (and why: set on vehicle, by axles, by registered weight or by maximum weight), Miles, Gallons, MPG and GPS gap miles.
Read a distance tax return
A distance tax return lists each vehicle that drove in the jurisdiction with its Weight (the charged weight), Distance, the rate and the Tax. Depending on the scheme you also see Axles, Method (the weight band and rate table used), Vehicle type (New Zealand), Euro class and Tonne-km (Switzerland). The rate column follows the scheme: per mile or km, Rate per tonne-km or Rate per 1,000 km. Under the table you see the legal basis, the date the rates took effect, the confidence of the research and the Rate source.
Read a fuel tax refund
At the top you see Refundable litres, Total refund and, when they apply, Related aids, Refund + aids and Litres above cap.
- Per jurisdiction: the eligible litres bought in each jurisdiction, the Refundable rate on the purchase date and the Refund.
- Related temporary aids: each aid with its jurisdiction, litres, rate, amount and status.
- Per vehicle: whether the vehicle is Eligible, its litres, the litres Above cap, the GPS distance where a cap per km applies, the refund and aid, and in Notes why a vehicle is not eligible or which data is missing.
Check the warnings
Read the warnings before you file. The most common ones:
| Warning about | What to do |
|---|---|
| Distance across GPS gaps | Check the vehicle's trips in that period. The distance is counted along a straight line. |
| A vehicle bought fuel but has no GPS positions | Its distance is missing. Check its board computer or tracking. |
| Whether a vehicle qualifies is unknown | Fill in its axles or registered weight in Fuel & road taxes on the vehicle. |
| Fuel transactions without a vehicle, without a member jurisdiction, or with a unit that cannot be converted | Correct the transactions. Until then they are left out, or no credit is taken for them. |
| No rate for a jurisdiction, or preliminary rates | Wait for the final rates or add a rate override in the settings. |
| Registered weight or axles missing | The maximum weight or the lowest axle count is used. Fill in the vehicle data. |
| Rates for part of the period, or an excise rate, are missing | The refund is incomplete. Check the official rates and add a rate override. |
| A vehicle is not eligible, or its eligibility is unknown | Fill in its registered weight, Vehicle category (UNECE) or emission standard. |
| A refund cap is reached | Fuel above the cap is not refunded. |
| Vehicle type, emission class or trailer weight missing | Fill in the RUC vehicle type (New Zealand), the Emission standard or the Gross weight of the usual trailer on the vehicle. |
| The period has not ended yet | The return covers the days so far. |
Export and file
- Open the return of the scheme and period.
- Click Export to Excel. The file holds the lines, the vehicles, the warnings and your licence number.
- Transfer the figures to the return in the portal of your base jurisdiction or tax authority, and file it before the due date.
IFTA returns are due on the last day of the month after the quarter: 30 April, 31 July, 31 October and 31 January; a due date on a weekend moves to the next working day. New York, Kentucky, New Mexico and Connecticut use the same days; quarterly Oregon filers file by the end of the second month after the quarter. Some schemes have no filing date in Transportial: the Spanish and Portuguese refunds are settled from fuel-card data, Australian fuel tax credits are claimed on your business activity statement, and New Zealand's road user charges, the Swiss heavy vehicle charge and the Icelandic kilometre charge are prepaid or invoiced by the authority. The page shows the due date of the period you opened when there is one.
Most tax authorities expect a return every period, also when you drove no miles there.
Send the return automatically
A message automation can email the return as an Excel file every quarter, for example to your accountant.

- Enter a File name and save the automation.
See Write the message and add attachments for the rest of the message.
