IFTA for Alberta carriers: records, returns and common mistakes
If your trucks cross provincial or state lines, IFTA decides how much fuel tax each jurisdiction gets. Here's who needs a licence, how the quarterly return works, the records that protect you in an audit, and the mistakes we see most.
Key takeaways
- You need IFTA if a qualified vehicle travels outside Alberta. Alberta-only carriers don't
- Returns are due quarterly (Apr 30, Jul 31, Oct 31, Jan 31), even in a quarter with no travel outside Alberta
- The return is only as good as your distance and fuel records by jurisdiction
Every province and state taxes the fuel used on its roads. When a truck fills up in Alberta and burns that fuel in Saskatchewan and British Columbia, those jurisdictions are owed their share. The International Fuel Tax Agreement (IFTA) sorts that out with one quarterly return, instead of a separate fuel tax account in every place you drive.
This article is part of our guide to the financial side of running a trucking company.
Do you need an IFTA licence?
You need one if you're based in Alberta and run a qualified motor vehicle outside the province. A qualified motor vehicle is used to carry people or property and has:
- two axles and a gross vehicle weight (or registered gross vehicle weight) over 11,797 kg (26,000 lb), or
- three or more axles, whatever the weight, or
- a combined truck and trailer weight over 11,797 kg.
In Alberta, IFTA is run by Tax and Revenue Administration (TRA), part of Alberta Treasury Board and Finance. You file one return with TRA, and it shares the money out to the other jurisdictions.
Alberta-only carriers don't need IFTA. If you only occasionally leave the province, you can buy a fuel tax trip permit for those trips instead. If you're crossing borders every month, the licence is simpler.
How the quarterly return works
Each quarter, for every jurisdiction you drove in, you report:
- The kilometres driven there (all of them, loaded and empty)
- The fuel bought there, tax-paid
Your fleet's overall fuel economy is used to work out how much fuel you burned in each jurisdiction. Each jurisdiction then gets tax on the fuel you burned there, with credit for the tax you already paid at the pump there.
Example: one quarter, one truck
An owner-operator based in Grande Prairie hauls lumber to Saskatchewan and back-hauls from BC. Over the quarter:
| Jurisdiction | Kilometres | Litres bought |
|---|---|---|
| Alberta | 18,000 | 9,500 |
| Saskatchewan | 9,000 | 1,200 |
| British Columbia | 6,000 | 1,800 |
| Total | 33,000 | 12,500 |
Fuel economy: 33,000 km ÷ 12,500 L = 2.64 km per litre (about 38 L/100 km).
| Jurisdiction | Fuel burned (km ÷ 2.64) | Fuel bought | Difference |
|---|---|---|---|
| Alberta | 6,818 L | 9,500 L | Bought 2,682 L more than burned → credit |
| Saskatchewan | 3,409 L | 1,200 L | Burned 2,209 L more than bought → tax owing |
| British Columbia | 2,273 L | 1,800 L | Burned 473 L more than bought → tax owing |
Each "difference" is multiplied by that jurisdiction's fuel tax rate for the quarter. The credits and amounts owing net out to one payment (or a refund) through TRA.
The pattern is common for Alberta carriers. Fuel tends to be bought at home and burned elsewhere, so you usually owe the other provinces and get a credit in Alberta.
Rates change every quarter
Fuel tax rates are published each quarter, and Alberta's own fuel tax is currently adjusted quarterly under its Fuel Tax Relief Program. Always use the official rate table for the quarter you're filing. Don't reuse last quarter's rates. We've left actual rates out of the example for that reason.
Deadlines
Returns are due on the last day of the month after each quarter:
| Quarter | Due |
|---|---|
| January–March | April 30 |
| April–June | July 31 |
| July–September | October 31 |
| October–December | January 31 |
You must file even if you didn't travel outside Alberta that quarter. A late return can cost a penalty of $50 or 10% of the unpaid tax, whichever is greater, plus interest.
The records that protect you
An IFTA audit tests your records, not your return. The return is only as good as what backs it up.
For distance, keep trip records for each vehicle and trip showing:
- dates, origin and destination, and the route
- kilometres driven in each jurisdiction
- odometer or hubometer readings at the start and end
- the unit number
ELD data and GPS reports are a big help, but make sure you can produce a per-trip, per-jurisdiction record from them. The ELD's hours-of-service view on its own isn't enough.
For fuel, keep receipts or fuel-card statements showing the date, seller, location, litres, fuel type, price, and the unit fuelled.
IFTA requires these records to be kept for four years from the return's due date or filing date, whichever is later, and longer if an audit is under way. Keep your tax records for at least six years anyway, for the CRA.
The mistakes we see most
- Leaving out deadhead kilometres. Every kilometre counts, loaded or empty.
- Fuel on the wrong unit. One driver uses another truck's card and two trucks' fuel economy goes wrong. Catch it in your month-end routine.
- Bulk fuel with no withdrawal log. If you fuel from your own tank in the yard, you need records of what went into which truck.
- Personal or non-qualified use mixed in. A pickup with a gooseneck might or might not be a qualified vehicle. Decide, and keep its records separately.
- Estimating distance from a map after the fact. Auditors look for actual trip records.
- Missing the nil return. "We didn't leave Alberta this quarter" still needs a return.
How IFTA connects to the rest of your books
The same per-jurisdiction fuel and distance records also feed your cost per kilometre, your fuel-card reconciliations, and the travel records behind meal claims on the road. Keeping them well once pays off in several places.
The bottom line
IFTA isn't hard. It's detailed, and it punishes a messy quarter. If you'd like the records kept monthly and the return prepared and filed for you, that's part of how we help carriers.
