The International Fuel Tax Agreement (IFTA) is a tax collection agreement between the 48 contiguous US states and 10 provinces of Canada. It simplifies fuel tax reporting for motor carriers travelling both inside and outside California. Diesel fuel is subject to the use fuel tax under IFTA, and vehicles that operate on diesel fuel are considered qualified motor vehicles. IFTA taxes are calculated based on the number of gallons of diesel fuel purchased and the miles travelled in each jurisdiction. Carriers must maintain documentation to support claims of tax-exempt miles, and IFTA returns are due quarterly.

IFTA credentials are invalid in some jurisdictions
The International Fuel Tax Agreement (IFTA) is a tax collection agreement between the 48 contiguous states of the United States and the 10 provinces of Canada. It is designed to reduce the administrative burden of reporting motor fuel taxes in multiple jurisdictions.
However, it's important to note that not all jurisdictions are part of the IFTA. Alaska, Hawaii, and the District of Columbia in the United States, along with Canada's Northwest Territories, Nunavut, and Yukon Territory, as well as all the states and the Federal District of Mexico, are not members of IFTA. Carriers travelling in these jurisdictions must follow the specific reporting requirements mandated by these non-IFTA jurisdictions, even if they hold an IFTA license. For example, motor carriers travelling exclusively between Texas and Mexico are ineligible for an IFTA license and must instead obtain a Texas interstate trucker license or a fuel trip permit for each entry into Texas.
In California, if your vehicle's travel is restricted solely to the state, you are not required to hold an IFTA or Interstate User Diesel Fuel Tax License. However, if you do hold an IFTA license and travel in a non-IFTA jurisdiction, you must adhere to the procedures and filing requirements for fuel tax returns in those areas.
To maintain an active IFTA account, it is essential to renew your IFTA license and decals annually. Failure to renew or file IFTA tax returns may result in penalties, fines, or even suspension of your credentials. It is also important to carry a copy of your current, valid IFTA license when operating a qualified motor vehicle to avoid potential citations, fines, or vehicle seizures.
In summary, while IFTA simplifies fuel tax reporting across multiple jurisdictions, it is crucial to recognise the limitations of its validity. Carriers must be aware of the specific requirements and exemptions of each jurisdiction they operate in, especially those outside the scope of IFTA.

IFTA miles and taxable miles
IFTA, or the International Fuel Tax Agreement, is a tax collection agreement between the 48 contiguous US states and 10 provinces of Canada. It aims to reduce the administrative burden of reporting motor fuel taxes in multiple jurisdictions.
IFTA miles, or taxable miles, refer to the miles travelled by a qualifying vehicle in an IFTA jurisdiction. These include empty miles, personal conveyance miles, and miles covered while moving to mechanic shops or around yards. IFTA miles are used to calculate the fuel tax owed in each jurisdiction.
To calculate the IFTA tax, you must first determine the total miles driven in each jurisdiction. This can be done using trip logs, odometer readings, or GPS tracking. Next, calculate the overall fuel mileage by dividing the total miles driven by the total gallons purchased. Then, determine the fuel consumed per jurisdiction by dividing the total miles driven in that jurisdiction by the overall fuel mileage. Finally, apply the jurisdiction's tax rate to calculate the tax owed.
It is important to note that some jurisdictions, such as California, consider only the miles travelled under a valid California Fuel Trip Permit (CFTP) as tax-exempt miles for the purposes of the IFTA quarterly return. Additionally, certain miles travelled by motor carriers may be defined as tax-exempt by some IFTA jurisdictions. It is the responsibility of the carrier to know and understand what miles are considered tax-exempt in each jurisdiction.
IFTA tax returns are due quarterly, and failure to file and pay the applicable tax may result in penalties.

IFTA tax deductions
The International Fuel Tax Agreement (IFTA) is a tax collection agreement between the 48 contiguous US states and 10 provinces of Canada. It aims to reduce the administrative burden of reporting motor fuel taxes in multiple jurisdictions.
Firstly, it is important to understand what constitutes a qualified motor vehicle. A qualified motor vehicle is one that is used for the transportation of people or property and meets specific weight criteria. Recreational vehicles are explicitly excluded from this category. If your vehicle meets the definition of a qualified motor vehicle, you must obtain an IFTA license and fuel decals if travelling in jurisdictions that require them.
Secondly, you must keep detailed records of your fuel purchases and mileage. Your IFTA tax is calculated based on the number of gallons of fuel burned in each state and the miles travelled in each jurisdiction. You can then determine the tax owed to each jurisdiction. It is essential to maintain these records for at least four years, as required by IFTA and IRP guidelines.
Additionally, certain jurisdictions may have specific requirements for tax deductions. For example, California requires a California Fuel Trip Permit (CFTP) for miles to be considered tax-exempt for the purposes of the IFTA quarterly return. It is important to review the regulations for each jurisdiction in which you operate to ensure compliance with their specific rules.
Lastly, when claiming IFTA tax deductions, ensure that you have the necessary documentation to support your claims. For instance, a credit card receipt for fuel purchases must be provided, and it should not contain any alterations or erasures to be considered valid. By following these guidelines and staying informed about the specific requirements of each jurisdiction, you can effectively manage your IFTA tax deductions.

IFTA license qualifications
IFTA, or the International Fuel Tax Agreement, is a tax collection agreement between the 48 contiguous states of the United States and the 10 provinces of Canada. It aims to simplify fuel tax reporting for interstate carriers by reducing the administrative burden of reporting motor fuel taxes in multiple jurisdictions.
IFTA qualifications and requirements vary depending on the state or province. Here are the general qualifications and requirements for obtaining an IFTA license:
Vehicle Requirements
A qualified motor vehicle for IFTA is one that is used, designed, or maintained for the transportation of persons or property. It must meet at least one of the following criteria:
- Have two axles and a gross vehicle weight (GVW) or registered GVW exceeding 26,000 pounds (11,797 kilograms).
- Have three or more axles, regardless of weight.
- Be used in combination with a trailer, resulting in a combined GVW or registered GVW exceeding 26,000 pounds.
Recreational vehicles, government-owned vehicles, and school buses are generally exempt from IFTA licensure. However, school buses may need an IFTA license if they meet the definition of a qualified motor vehicle and travel in jurisdictions that require it.
Operational Requirements
To qualify for an IFTA license, you must operate your qualified motor vehicle in two or more member jurisdictions. For example, if your base jurisdiction is California, your vehicle must travel in California and at least one other member state or province.
Registration and Record-Keeping
You must register your qualified motor vehicles in your base jurisdiction, which is typically where you maintain operational control and records for your vehicles. You must also maintain or make available these operational records in your base jurisdiction.
Licensing and Renewal
To obtain an IFTA license, you must apply through your base jurisdiction. The application process may vary, but it generally requires basic information about your business and operations. There is typically no fee for the license, which is valid from January 1 through December 31 of each year.
You must renew your IFTA license and decals annually, and you may do so online in some jurisdictions. Renewal fees may apply, and you must purchase new decals for each qualified motor vehicle in your fleet.
Fuel Tax Reporting
IFTA licensees are required to file a quarterly fuel tax return, even if they did not travel or purchase fuel during the reporting period. The return includes the total miles travelled and total gallons of fuel purchased in all participating jurisdictions. This information is used to calculate the tax liability for each jurisdiction.
To support your tax reporting, you must retain documentation for fuel deliveries and fuel tax exemptions. Proper receipts for fuel deliveries must be provided, and alterations or erasures may result in invalidation. All jurisdictions require documentation to support claims of tax-exempt miles.
Trip Permits
If your qualified motor vehicle travels only occasionally in multiple IFTA member jurisdictions, you may obtain a trip permit for each jurisdiction instead of an IFTA license. The number of trip permits is limited to ten per calendar year. Trip permits may also be issued as temporary vehicle licenses or for other purposes.
In summary, IFTA license qualifications include operating a qualified motor vehicle in multiple member jurisdictions, registering and maintaining records in your base jurisdiction, and regularly reporting fuel tax and mileage information. By understanding and meeting these qualifications, carriers can benefit from the simplified fuel tax reporting that IFTA offers.

IFTA tax reporting
The International Fuel Tax Agreement (IFTA) is a tax collection agreement between the 48 contiguous US states and 10 provinces of Canada. It aims to reduce the administrative burden of reporting motor fuel taxes in multiple jurisdictions.
IFTA tax reports should be filed quarterly and electronically using Webfile. Paper reports are accepted in cases of hardship when electronic filing is not possible. The due date is the last day of the month following the end of the calendar quarter. If this date falls on a weekend or holiday, the next business day is considered the due date.
The fuel tax report should list the miles travelled in all participating jurisdictions and the gallons of fuel purchased. This information is used to calculate the average fuel mileage, which is then applied to the miles travelled to determine the tax liability for each jurisdiction. Any fuel taxes due are then paid to the base jurisdiction that issued the license, and they will take care of transferring the funds accordingly.
To get a credit for tax-paid purchases, licensees must retain supporting documents as evidence. This can include a receipt, invoice, credit card receipt, or automated vendor-generated invoice. The documentation must include the date of purchase, fuel type, seller's name and address, vehicle registration number, purchaser's name, total cost, and gallons purchased.
IFTA tax reports include a combination of diesel/kerosene, gasoline, ethanol, propane, liquid natural gas, compressed natural gas, biodiesel, gasohol, methanol, A-55, E-85, and M-85.
