The purpose of this legislation, known as the Internal Revenue Service Math and Taxpayer Help Act, is to improve how the Internal Revenue Service (IRS) communicates with taxpayers regarding mathematical and clerical errors on their tax returns. The goal is to make these notices clearer and more informative, helping taxpayers understand the errors and how they can resolve them. Key provisions of the law require that any notice sent to a taxpayer about a math or clerical error must include specific details.
