Tax Services • Published 3/19/2018 Key Changes Brought by the Tax Reform Bill


On December 20, 2017, Congress approved the Tax Cut and Jobs Act which inititated sweeping changes to the U.S. Internal Revenue Code.  While many of the provisions are effective as of January 1, 2018 and are permanent, a number of provisions, especially on the individual side, sunset on or after December 31, 2025.  Below is a brief outline of several key changes that are likely the most relevant to individuals and private business owners.
