On April 21, 2017, President Trump issued Executive Order No. 13789, ordering the Secretary of the Treasury to
immediately review all significant tax regulations issued by the Department of the Treasury on or after January 1, 2016, and, in consultation with the Administrator of the Office of Information and Regulatory Affairs, Office of Management and Budget, identify in an interim report to the President all such regulations that:
(i) impose an undue financial burden on United States taxpayers;
(ii) add undue complexity to the Federal tax laws; or
(iii) exceed the statutory authority of the Internal Revenue Service.
The interim report is due June 21, 2017. A report recommending specific actions is due September 18, 2017, with actions to be taken within 180 days thereafter. The reason for the issuance of Executive Order 13789 is stated therein as follows:
The Federal tax system should be simple, fair, efficient, and pro-growth. The purposes of tax regulations should be to bring clarity to the already complex Internal Revenue Code (title 26, United States Code) and to provide useful guidance to taxpayers. Contrary to these purposes, numerous tax regulations issued over the last several years have effectively increased tax burdens, impeded economic growth, and saddled American businesses with onerous fines, complicated forms, and frustration. Immediate action is necessary to reduce the burden existing tax regulations impose on American taxpayers and thereby to provide tax relief and useful, simplified tax guidance.
