The Federal Register is the document that compiles all the federal rules and regulations that businesses are required to comply with. As of 2010 the Federal Register was 81,405 pages long. Federal regulations serve as a hidden tax on the economy. Costs imposed by regulation do not end up on any Federal budget, nor do they add to the national deficit. However, 81,405 pages of regulations strain the economy by creating huge costs that business are obligated to meet.
