Return preparers must be ready for how the Tax Cuts and Jobs Act has modified many common features of individual and business returns.

Tax practitioners have known and discussed the tax law changes for 2018 returns for more than a year since the Dec. 22, 2017, passage of the law known as the Tax Cuts and Jobs Act (TCJA), P.L. 115-97. But even forearmed with that knowledge, CPAs now face a daunting task putting those new and revised provisions into practice.

While the Service has issued proposed regulations upon which taxpayers may rely in many areas, such as the new Sec. 199A qualified business income (QBI) deduction described later, those proposed regulations and many others still leave unanswered questions.
