I would like to continue the topic of transportation firms in USA and their taxes. As you should know, IFTA fuel tax is the most important for trucking firms in this country. There are many methods of dealing with IFTA filing (it's preparing documents connected with fuel tax). I think that the best option is to use an IFTA software placed on www.ifta.biz. This application will help you to calculate your tax very fast and without paying big money for that.
