The purpose of this legislation, known as the IRS Accountability and Taxpayer Protection Act, is to improve the procedures related to penalties imposed by the Internal Revenue Service (IRS). It aims to ensure that taxpayers are treated fairly and transparently when penalties are assessed against them. One of the key provisions of this act is that any penalty or disallowance period cannot be applied unless it has been personally approved in writing by the immediate supervisor of the IRS employee making the determination.
