Many accounting and finance practitioners have had difficulty understanding and applying the One Big Beautiful Bill Act (OBBBA)/H.R.1. Accounting and finance practitioners are still confused and challenged by many of the new and extended tax provisions that the H.R.1/OBBBA delivered. Mastering these crucial provisions requires multiple exposures to these challenging tax changes. This program is a four-hour review and analysis of the most important changes from the H.R.1/OBBBA that impact both individual and business taxpayers. This course affords accounting and finance practitioners an opportunity to gain a broader, deeper understanding of this wide-ranging set of new tax rules, to grasp what is new and what is a continuance of prior rules, and to develop deeper planning insights into the many changes that the H.R.1/OBBBA contains. To the extent that the Treasury has provided guidance relating to OBBBA changes, we will discuss that guidance. We will also point out areas where Treasury guidance would be useful and areas where guidance is expected.
