Box Truck Mileage and Fuel Reporting

Hello,
Hoping someone point me in the right direction. Been in trucking for several years and have my own authority. Up until recently I have only had a sleeper truck and have been reporting and filing my fuel and mileage to IFTA without issues. I have just purchased a box truck and use that mainly to run Amazon loads. My business is registered in NC and have been running the box truck in NC and VA so far.

My question is, should I be tracking and reporting the fuel purchases and mileage for the box truck to IFTA as well? I was under the impression I didn't need to because the gross weight of the truck is under 26,000 pounds. Just trying to make sure I am reporting correctly and understanding the do's and don'ts.

Any help with this or links to the information I need is greatly appreciated.

 

The truck does cross state lines on occasion. It has NC For Hire plates.
