What is IFTA?

So what is IFTA, exactly?

IFTA is the International Fuel Tax Agreement.  Through IFTA, member jurisdictions act cooperatively to collect and administer taxes related to motor fuel usage.

The purpose of IFTA is to establish and maintain the concept of one fuel use license for interstate carriers and one administering base jurisdiction for each license holder. An IFTA license allows a taxpayer to file one tax report that covers all member jurisdictions.

How does IFTA work?

The IFTA operating principle:

  • Fuel tax owed is calculated based on where the fuel was consumed.
  • Tax credit is determined by where the fuel was purchased.
  • IFTA finds the difference between fuel consumed and fuel purchased for each jurisdiction.

IFTA Rates – Each member jurisdiction sets its own tax rate (and you can access all jurisdictions IFTA rates from 2010 to today in eTrucks).

Filing deadlines for each quarter – April 30th for Quarter 1, July 31st for Quarter 2, October 31st for Quarter 3, and January 31st for Quarter 4. Late filing will result in late penalties and/or interest rates.

Penalties – A penalty of $50 or 10% of delinquent taxes, whichever is greater, will be charged for failing to file a tax return, filing a late tax return, and underpaying taxes due.

Interest Rates – The current IFTA annual interest rate is 6% (increasing to 7% in 2019). Your base jurisdiction, for itself and on behalf of other jurisdictions (states/provinces) will charge interest on all delinquent taxes due to each jurisdiction, except IFTA taxes already collected by other jurisdictions according to IFTA procedures.
