WASHINGTON - The Internal Revenue Service today released the 2010 version of its discussion and rebuttal of many of the more common frivolous arguments made by individuals and groups that oppose compliance with federal tax laws.

Anyone who contemplates arguing on legal grounds against paying their fair share of taxes should first read the 80-page document, The Truth about Frivolous Tax Arguments.

The document explains many of the common frivolous arguments made in recent years and it describes the legal responses that refute these claims. It will help taxpayers avoid wasting their time and money with frivolous arguments and incurring penalties.

Congress in 2006 increased the amount of the penalty for frivolous tax returns from $500 to $5,000. The increased penalty amount applies when a person submits a tax return or other specified submission, and any portion of the submission is based on a position the IRS identifies as frivolous.

IRS highlighted in the document about 40 new cases adjudicated in 2009. Highlights include cases involving injunctions against preparers and promoters of Form 1099-Original Issue Discount schemes and injunctions against preparers and promoters of false fuel tax credit schemes.
