What is the primary use of the IRS Publication 17?

The primary use of IRS Publication 17 is to provide guidance for individual taxpayers on how to file their tax returns. This publication serves as a comprehensive resource that covers a wide range of topics relevant to individual taxpayers, including who must file, how to report income, what deductions and credits may be applicable, and the general filing process. By presenting this information in an accessible format, Publication 17 aims to help taxpayers navigate the complexities of the tax system and ensure they comply with tax laws while maximizing potential refunds or minimizing liabilities.

The other options address important aspects of taxation but do not define the main purpose of Publication 17. While it does touch on tax deductions and credits, as well as some filing nuances for business-related activities, its primary focus remains squarely on assisting individual taxpayers. Tax rates and rules specific to businesses are addressed in other IRS publications or documents, which means they are not the central focus of Publication 17.
