Thank you. This is just a discussion draft and not law, correct?

It is worth noting, however, that the Joint Committee on Taxation's Congressional Blue Book takes a contrary viewpoint to the IRS's Form 1040 instructions when it comes to the ability to take both the DPAD and the QBI deduction. The IRS indicated in informal phone conversations that it has taken its position due to the way the original transition rule for the DPAD operated back in 2005. In 2005, individuals were not allowed a DPAD deduction for a fiscal year that began in 2004 and ended in 2005. The allowance of the full DPAD in 2018 is to balance out that original rule. The positions in the Congressional Blue are not binding to the IRS, and to date, the IRS maintains its viewpoint that both of these deductions apply in 2018.
