There is a lot to keeping track of the information required to make sure you are in compliance with the tax laws impacting your operation. You should keep a monthly financial statement, make quarterly tax deposits and file the required documents on time (e.g., estimated quarterly taxes, Heavy Road Use Form 2290, and annual income tax reports. In addition, there are things you need to consider the impact of longer term (e.g., should you incorporate?) and plan for according (e.g., your retirement). Given the hours of time and attention you already give to your driving, you may not have time to keep track of these requirements. In addition, as tax laws change, failure to accommodate those changes in your recordkeeping and reporting can result in you not making deductions that your should or finding yourself paying fines for misreporting.
