Each company must register with the Internal Revenue Services International Fuel Tax Department and stay up to date. Your registration must be renewed every year and fuel taxes must be files each quarter. Fuel tax reports due at the end of each fiscal quarter must include all miles traveled and list of gallons purchased at the time. (Kentucky, New Mexico, New York and Oregon must be computed differently). We can calculate your IFTA reports to safeguard you from a suspended license or high penalties.
